Intel 335 Series 180GB SSD

Intel has had a prominent role in the consumer solid-state drive (SSD) market since it launched its 80GB X25-M solid-state drive back in 2009. The chip giant has followed up with refreshed devices at regular intervals, most recently with the SSD 335 Series. The 180GB 335 Series drive we're reviewing today is the second SKU to launch; Intel shipped a larger 240GB model last December. This new drive is a decent performer, but its reliance on older controller technology leave it wedged in the middle of the pack.

There's not much difference between the new SSD 335 Series drives and the 330 Series, which launched a little over a year ago. Both the 330 and 335 families use the SandForce SF-2281 controller. Both offer SATA 6G support, a three-year warranty, and the same base performance specs (500MBps sequential read and 450MBps sequential write). The older drive uses 25nm MLC NAND, while the newer 335 Series is based on Intel's 20nm NAND. SSDs aren't known for drawing much power, but the 335 is specced as having a maximum power draw of 350mW, with idle power consumption of 275mW. That's significantly less than the SSD 330 Series, which was specced for 850mW under load and 600mW in idle.

Save for the reduced power consumption, the shift to 20nm NAND is mostly an advantage for Intel, rather than a direct benefit to consumers. The 20nm NAND is significantly smaller than 25nm NAND, which means Intel can fit more memory chips on a given silicon wafer. The shift to smaller manufacturing geometries (also called nodes) is one reason why the price of SSDs has dropped precipitously in the past few years. The new 20nm NAND chips (shown to scale in the image above), are just 40% the size of the 34nm NAND Intel was using four years ago.

Intel drives tend to carry a fair amount of additional (overprovisioned) Flash. The 180GB SSD 335 actually contains 192GB of RAM; the additional 12GB is rotated into use as blocks of the original 180GB wear out and need to be retired. One of the downsides to using NAND built on a smaller process is that the memory can't handle as many program/erase cycles. Despite this trend, Intel rates the SSD 335 is as robust as the previous SSD 330 family.

We compared the 180GB Intel SSD 335 against the Samsung 840 Pro Series 256GB and the OCZ Vector Series VTR1-25SAT3-256G. Our review unit was tested using an Asus P877V-Deluxe motherboard with 8GB of DDR3-1600 and an Intel Core i7-3770K CPU. The P877-V Deluxe offers multiple SATA controllers from Intel and Marvell; all of the drives were connected to Intel's 6G SATA port.

Of principle interest here is whether the 335's older SandForce controller can keep up with newer options from OCZ and Samsung. The SF-2281 controller has mostly been popping up in budget drives of late, and SandForce is expected to launch a new SF-3000 controller series later this year.

The performance figures for AS-SSD and SiSoft Sandra tests reflect a drive's performance in a particular type of data workload. Sequential read/write tests measure an SSD's capabilities when reading or writing a large block of contiguous data. A single large movie or ISO image will test a drive's sequential performance (assuming that the target drive isn't badly fragmented). In AS-SSD, the Intel 335's sequential read speeds weren't far off the OCZ Vector and Samsung 840 Pro (465MBps compared to 509 MBps and 518 MBps, respectively), but sequential write performance was significantly lower. The Intel 335 managed 252MBps, while the OCZ Vector clocked in at 495MBps and the Samsung 840 Pro scored 481MBps.

The 4K read/write tests ascertain the performance of an SSD or HDD when reading and writing small chunks of data. These small read/writes are vital to the everyday performance of a storage solution. The "64 Threads" test in AS-SSD means that the benchmark program spins off 64 separate 4K read/write tasks. This stretches the controller's ability to manage such workloads, but also provides a more realistic performance metric?an operating system is constantly reading and writing data to multiple services and programs simultaneously. The Intel 335 lagged behind the OCZ and Samsung drives at 203MBps read and 214MBps write. The OCZ Vector logged read/write speeds of 359MBps and 304MBps with the 840 Pro at 381MBps read, 299MBps write.

The random read/write performance data from SiSoft Sandra that we also quote is a measure of a drive's sustained performance when reading and writing a contiguous block of information to a randomly chosen location. These metrics are important because they collectively measure the different types of storage tasks an SSD or HDD performs, even if they don't represent user workloads.

SiSoft Sandra again shows the Intel 335 competing well in read performance (485MBps, while the OCZ Vector and Samsung 840 Pro both tie at 530MBps). Write performance is the drive's weak spot -- the Intel 335's SF-2281 controller turns in 225MBps in random write performance. That's less than half the OCZ Vector's 509MBps random write or the Samsung 840 Pro's 507MBps.

Finally, there's PCMark 7, which is a different type of test. The benchmark uses real storage workloads created by recording traces of hard drive activity when playing games, loading music or video, or copying files. These traces are used to measure the performance of storage products in comprehensive real-world scenarios.

The difference between SSDs in PCMark 7 tends to be much smaller than what we see in other synthetic tests. The Intel 335 scored a 5214, compared to a 5419 for the OCZ Vector and a 5588 for the Samsung 840 Pro. The gap between the Intel SSD 335 and the other drives is roughly ~7%.

Right now, the Intel 335 Series 180GB is selling for about $175, or just under $1 per GB. That compares fairly well to the cost-per-GB of an OCZ Vector ($269 for 256GB at NewEgg) or the Samsung 840 Pro ($249 for 256GB at NewEgg). The OCZ and Samsung options, however, are significantly faster than the Intel 335 Series. The SF-2281 controller has migrated to budget SSDs for a reason; it was cutting edge when it debuted in 2011, but its performance has been surpassed by other products.

That doesn't mean the Intel 335 is devoid of strong points. Intel has over-provisioned the drive by about 6.7%, which is fairly high for consumer hardware. The company has a reputation for high-quality NAND flash, and the included SSD toolbox software interfaces well with Windows and can auto-optimize an OS installation to run on solid state storage as well as manually triggering the TRIM command.

When push comes to shove, however, the Intel 335 Series 180GB SSD is in a bit of a no-man's land. There are budget drives, like Samsung's 840, that offer a lower cost per GB. There are higher-performing drives for the same cost per GB. If you can grab one of the 180GB or 240GB drives on sale, or if you're fond of Intel-branded products, then the Series 335 180GB SSD is a good option. Other buyers will find newer hardware a better deal.

After Exiting From Crashpadder, Founder Hopes Pact Will Be The ?Zappos Of Coffee'

You can't really keep a good entrepreneur from continuing to launch companies. That appears to be the case once again with Stephen Rapoport. Rapoport previously built and sold the apartment-sharing site Crashpadder to Airbnb, but has since got itchy feet once again after exiting a few months ago. And what started out as a hobby business to keep him interested before the next big thing has turned into a much bigger project.

DAMASCUS, Syria (AP) ? Suicide bombers targeted security compounds in Damascus and a car bomb exploded in a pro-regime district there Sunday, killing at least eight people, the latest in a surge of civil war violence in the capital.

In northern Syria, a car bomb killed 12 soldiers in Aleppo, according to the Britain-based Syrian Observatory for Human Rights, which relies on a network of activists in Syria for information. It had no other details, and the government did not comment.

The state-run news agency SANA said three suicide bombers blew themselves up while trying to break into the Rukneddine police station in northern Damascus, killing five people and wounding several others. SANA said three would-be suicide bombers also tried to break into the Criminal Security Branch in the southern Bab Mousalla area but were caught by security forces before they could detonate their explosives.

Activists confirmed the death toll.

SANA said a car bomb exploded in Mazzeh 86 district in the capital, killing three people, including a 3-year-old boy. Residents of the district are mostly Alawites, an offshoot Shiite sect that President Bashar Assad's family belongs to. The opposition forces fighting against Assad's regime are mostly Sunni Muslims.

Nobody immediately claimed responsibility for the Damascus explosions, but they bore the hallmarks of al-Qaida-linked groups that have joined forces with rebels fighting to oust Assad.

The attacks in Syria's two largest cities came as government forces pressed an offensive on the outskirts of the capital.

SANA carried a statement by the Interior Ministry saying that the Damascus attacks were a "new escalation by terrorist groups," a term used by the government to refer to the rebels.

More than 93,000 people have been killed in Syrian conflict that started in March 2011 as peaceful protest against Assad's rule. In the past year, the war has taken on sectarian overtones.

The conflict has increasingly spilled across Syria's borders.

In neighboring Lebanon, clashes erupted between Lebanese military and supporters of hard-line Sunni cleric Sheik Ahmad al-Assar, a security official said. Three Lebanese soldiers were killed, he said speaking anonymously in line with regulations.

The fighting broke out in the predominantly Sunni southern port city of Sidon after al-Assir's supporters opened fire on an army checkpoint.

The military issued a statement confirming that three soldiers died in the shooting, including two officers. It said the shooting was unprovoked.

Heavy fighting with machine guns and rocket-propelled grenades caused panic in the city, which until recently had been largely spared the violence hitting other areas. Many people who were spending the day on the beach hurried home, while others living on high floors came down or fled to safer areas. Gray smoke billowed over parts of the city.

The clashes centered on the Bilal bin Rabbah Mosque, where al-Assir preaches. The cleric, a virulent critic of the Shiite militant Hezbollah group, is believed to have hundreds of armed supporters in Sidon. Dozens of al-Assir's gunmen also partially shut down the main highway linking south Lebanon with Beirut.

By Sunday evening, the army appeared poised to move against al-Assir and his supporters, who have been agitating for months. Lebanon's state-run National News Agency said the army have surrounded the mosque, sealing off access to it from all directions and neutralized hostile fire from neighboring buildings.

The NNA report said Assir was believed to be hiding inside the mosque with several of his followers.

The cleric and his followers support Sunni rebels in the Syria conflict, and he has threatened to clear apartments in Sidon where Hezbollah supporters live.

Sunday's clashes in Sidon deepened tensions in Lebanon. on edge since the Syrian conflict began more than two years ago.

Lebanese President Michel Suleiman called an emergency meeting of the security cabinet for Monday. NNA also reported sporadic shooting in the volatile city of Tripoli in the north, and the army announced additional force deployments in around Beirut.

The violence came a day after an 11-nation group that includes the U.S. met in the Qatari capital of Doha to coordinate military aid and other forms of assistance to the rebels.

Syria's al-Thawra newspaper, the mouthpiece of the government, assailed the Friends of Syria meeting.

"It's clear that the enemies of Syria are rushing to arm the terrorists to kill the chances for holding the Geneva conference," the newspaper said, referring to a U.S.-Russia initiative for bringing Assad's government and rebels together to negotiate an end to the crisis.

The Syrian paper pledged that the army would "continue the showdown to eliminate terrorism and restore security and stability."

Switched On: Touchy subjects

Each week Ross Rubin contributes Switched On, a column about consumer technology.

In 2002, the first LCD-based iMac succeeded the translucent PowerPC G3-based models that the original Bondi Blue iMac begat. The new generation was much more striking than the one that had placed Apple on the comeback trail. The iMac G4 mounted the display on a balanced arm similar to a Luxo lamp while the motherboard resided in a hemispherical base. This allowed the display to be adjusted to a wide range of heights and angles and each of the two main sections to be "true to itself."

Alas, the design had its limits. It's difficult to imagine today's ample 27-inch iMac displays balancing off such a mount. Furthermore, after the switch to Intel, processor thermals improved to help enable the slim iMac of today. The idea of efforts being true to themselves (at least until nearly compromise-free convergence is possible), however, has stayed a hallmark of Apple. For example, the company would resist adding video to the iPod for years after competitors had the feature.

Senate sets Monday vote in key test for immigration bill

WASHINGTON (Reuters) - Senate Democratic Leader Harry Reid on Friday set a vote for Monday on a border-security deal that is expected to push a landmark U.S. immigration bill to passage by the end of next week.

The Democratic-controlled Senate is expected to pass the White House-backed bill with broad bipartisan support, sending it to the Republican-led House of Representatives, where it faces more resistance. Reid scheduled the vote after negotiators completed writing the deal into the form of an amendment.

The deal, reached on Thursday in a bid to ease border security concerns and build Republican support, would double the number of federal agents on the U.S.-Mexican border to about 40,000 and provide them more high-tech surveillance equipment, including manned and unmanned aerial vehicles.

Reid hailed the accord, saying it "would put to rest any remaining critical concerns about border security," which had been a major stumbling block.

The bill faces a major challenge in the House, where many Republicans oppose its provisions for a pathway to citizenship for up to 11 million illegal immigrants in the United States.

Critics complain that the pathway amounts to "amnesty" for lawbreakers and would attract more illegal immigrants. Backers disagree, saying it would bring illegal immigrants out of the shadows and integrate them into American society.

House Speaker John Boehner has said he will not bring any immigration bill to the floor of his chamber for consideration unless it has the support of most of his fellow Republicans.

NEW YORK (AP) ? U.S. stock futures are rising, shaking off a jolt delivered to global markets by the Federal Reserve.

Dow Jones industrial futures are up 93 points to 14,794. S&P futures have added 12.1 points to 1,596. Nasdaq futures are up 17.25 points to 2,897.25.

The S&P slumped 2.5 percent Thursday, its biggest loss since November 2011, and the Dow plunged 356 points after Fed Chairman Ben Bernanke outlined plans to wind down the government's economic stimulus efforts.

There are no economic indicators due Friday, and it appears that many investors think Thursday's sell-off was an overreaction.

Still, Hong Kong's Hang Seng index has not recovered from an uptick in a measure of interbank stress in China, which could signal trouble ahead for the world's second largest economy.

Watchdog faults background check of NSA leaker

WASHINGTON (AP) ? A government watchdog testified Thursday there may have been problems with a security clearance background check conducted on the 29-year-old federal contractor who disclosed previously secret National Security Agency programs for collecting phone records and Internet data ? just as news media disclosed more information about those programs.

Appearing at a Senate hearing, Patrick McFarland, the U.S. Office of Personnel Management's inspector general, said USIS, the company that conducted the background investigation of former NSA systems analyst Edward Snowden, is now under investigation itself.

McFarland declined to say what triggered the inquiry of USIS or whether the probe is related to Snowden. But when asked by Sen. Jon Tester, D-Mont., if there were any concerns about the USIS background check on Snowden, McFarland answered: "Yes, we do believe that there may be some problems."

Meanwhile, new details emerged about the scope of two recently disclosed NSA programs ? one that gathers U.S. phone records and another that is designed to track the use of U.S.-based Internet servers by foreigners with possible links to terrorism.

Two new documents published Thursday by The Guardian newspaper ? one labeled "top secret" and the other "secret" ? said NSA can keep copies of intercepted communications from or about U.S. citizens indefinitely if the material contains significant intelligence or evidence of crimes.

McFarland declined after the Senate hearing to describe to reporters the type of investigation his office is conducting. Sen. Claire McCaskill, D-Mo., said she was told the inquiry is a criminal investigation related "to USIS' systemic failure to adequately conduct investigations under its contract."

"We are limited in what we can say about this investigation because it is an ongoing criminal matter," said McCaskill, chairwoman of the Senate subcommittee on financial and contracting oversight. "But it is a reminder that background investigations can have real consequences for our national security."

McCaskill's panel conducted the hearing jointly with Tester's subcommittee on efficiency and effectiveness of federal programs.

USIS, based in Falls Church, Va., said in a statement that it has never been informed that it is under criminal investigation. USIS received a subpoena from the inspector general's office in January 2012 for records, the statement said. "USIS complied with that subpoena and has cooperated fully with the government's civil investigative efforts," according to the company.

USIS declined to comment on whether it conducted a background investigation of Snowden. The company said it performs thousands of background investigations each year for OPM and other government agencies. "These investigations are confidential and USIS does not comment on them," the USIS statement said.

The background check USIS performed on Snowden was done in 2011 and was part of periodic reinvestigations that are required for employees who hold security clearances, according to McFarland and Michelle Schmitz, the assistant inspector general for investigations at OPM.

Schmitz said the investigation of USIS commenced later in 2011.

Booz Allen Hamilton, the company where Snowden was working at the time of the disclosures, fired him for violations of the firm's code of ethics and firm policy. The company said he had been a Booz Allen employee for less than three months.

Snowden worked previously at the CIA and probably obtained his security clearance there. But like others who leave the government to join private contractors, he was able to keep his clearance after he left and began working for outside firms.

Of the 4.9 million people with clearance to access "confidential and secret" government information, 1.1 million, or 21 percent, work for outside contractors, according to a January report from the Office of the Director of National Intelligence. Of the 1.4 million who have the higher "top secret" access, 483,000, or 34 percent, work for contractors.

OPM's Federal Investigative Services division performs almost all the background investigations for federal agencies and nearly 75 percent of the investigators who perform background checks are contractors, according to information on the agency's website.

At the hearing, McFarland called for much closer oversight of the investigators who conduct background checks. He said that 18 background investigators and record searchers have been criminally convicted since 2006 for fabricating information in background reports.

McFarland's office is actively working on 11 fabrication cases and another 36 cases involving background investigators are pending, according to data he provided to the subcommittees.

Of the 18 investigators who were criminally convicted, 11 were federal employees and seven were contractors. Of the 47 active and pending cases, six involve federal employees and 41 involve contractors, according to McFarland.

The new documents revealed by The Guardian were signed by Attorney General Eric Holder. They include point-by-point directions on how an NSA employee must work to determine that a person being targeted has not entered the United States. If NSA finds the target has entered the U.S., it will stop gathering phone and Internet data immediately, the documents say.

If supervisors determine that information on a U.S. person or a target who entered the U.S. was intentionally targeted, that information is destroyed, according to the documents.

But if a foreign target has conversations with an American or a U.S.-based person whom NSA supervisors determine is related to terrorism, or contains significant intelligence or evidence of crimes, that call or email or text message can be kept indefinitely. Encrypted communications also can be kept indefinitely, according the documents.

Administration officials had said the U.S. phone records NSA gathered could only be kept for five years. A fact sheet those officials provided to reporters mentioned no exceptions.

The documents outline fairly broad authority when the NSA monitors a foreigner's communications. For instance, if the monitored foreigner has been criminally indicted in the U.S. and is speaking to legal counsel, NSA has to cease monitoring the call. The agency, however, can log the call and mine it later so long as conversation protected by attorney-client privilege is not used in legal proceedings against the foreigner.

The NSA had no comment when asked about the newly revealed documents.

Four microphones, computer algorithm enough to produce 3-D ...

Blind people sometimes develop the amazing ability to perceive the contours of the room they're in based only on auditory information. Bats and dolphins use the same echolocation technique for navigating in their environment.

At EPFL, a team from the Audiovisual Communications Laboratory (LCAV), under the direction of Professor Martin Vetterli, has developed a computer algorithm that can accomplish this from a sound that's picked up by four microphones. Their experiment is being published this week in the Proceedings of the National Academy of Sciences (PNAS). "Our software can build a 3D map of a simple, convex room with a precision of a few millimeters," explains PhD student Ivan Dokmani?.

Randomly placed microphones

As incredible as it may seem, the microphones don't need to be carefully placed. "Each microphone picks up the direct sound from the source, as well as the echoes arriving from various walls," Dokmani? continues. "The algorithm then compares the signal from each microphone. The infinitesimal lags that appear in the signals are used to calculate not only the distance between the microphones, but also the distance from each microphone to the walls and the sound source."

This ability to "sort out" the various echoes picked up by the microphones is in itself a first. By analyzing each echo's signal using "Euclidean distance matrices," the system can tell whether the echo is rebounding for the first or second time, and determine the unique "signature" of each of the walls.

The researchers tested the algorithm at EPFL using a "clean" sound source in an empty room in which they changed the position of a movable wall. Their results confirmed the validity of the approach. A second experiment carried out in a much more complex environment ? an alcove in the Lausanne Cathedral ? gave good partial results. New tests using more microphones are very likely to yield improved results.

Mobile localization in buildings

The team's initial conclusions already point to interesting potential applications. "Architects could use this to design rooms ? for example concert halls or auditoriums ? based upon the specific acoustics they would like to create," says Dokmani?.

Applications in forensic science are also on the horizon: based on several recordings of the same setup, audio waves could yield information on elements in the room that cannot be seen. In the same vein, analyzing a telephone call from a person who is moving around a room could allow investigators to identify where the person is calling from.

Finally, it might be possible to implement this algorithm in mobile devices and use them to deduce location information inside buildings ? a place where GPS signals do not penetrate well. "There are already many applications, and we foresee many more. This is only the beginning!" concludes Dokmani?.

Seattle Shows Dramatic Increase in Apartments As Baby Boomers ...

Building apartments is incredibly popular, with an unprecedented 6,796 new apartments coming onto the Seattle market in 2013. Some critics think overbuilding is a real threat, since that?s what happened in the condo market just a couple of years ago. An influx of apartments is great news for renters, but for developers and investors, nailing profits can get more challenging. At the moment, apartment demands are high, but there?s some worry that a revival of single-family homes might come out of nowhere.

According to Seattle economic researcher Dick Conway, there are hints that single-family homes might come back in high demand. Conway says it?s impossible to guess whether apartments or homes will be more in demand in a few years. However, rents are slated to increase 30 percent in the coming five years according to Dupre + Scott Apartment Advisors. On the other hand, salaries are increasing only three to four percent per year, making affording rent a challenge.

The 2013 Record-Breaking Year

In Seattle, 77 new apartment projects are in the works which equals nearly 7,000 new units in 2013 alone. They likely won?t all be built, but even making the 60 percent mark will make it a record-breaking year. Overall, there are over 9,000 units expected to be built in the coming three years. It?s a bull market for apartments in Seattle, one that hasn?t been seen since the 1980s. However, it mortgage rates remain low, it will be more affordable to own rather than rent?which means investment properties will be highly desirable.

It?s estimated that people spend about 12.4 percent of their income on mortgage payments in the Seattle area. Back during the housing boom, people were paying nearly 21 percent of their income. Even though rent is slated to skyrocket, experts don?t think that will turn off young people who just aren?t interested in owning property.

Why the Young Won?t Buy

Pulling together a down payment is challenging at best, especially since a minimum of 20 percent down often required. Just a few years ago, zero to five percent was required. Experts who are predicting a single-family boom couple that with easier mortgage financing. It?s allegedly the best time to buy an apartment in Seattle, and that news is catching the eyes of baby boomers. Right now renting is still cheaper than owning in Seattle, but with rents hovering at $1,400 for a small 650-square foot studio, that won?t remain for long.

The apartments might be small, but they?re often LEED-certified and luxurious (these aren?t the micro apartments popping up near Pike Place Market). The job growth in the area is strong, wages are relatively high and Seattle is a tech-rich city. Both young people and baby boomers are looking to live in smaller spaces while being close to downtown. However, as young people start thinking about families, they may be more inclined to give up city life for home ownership in the suburbs.

The surge in investment and banking is being taken advantage of by baby boomers. Whether they want to live in these swank apartment or snap them up and then rent them out (at 30 percent higher than the rental costs now), both are good moves. This will also benefit the economy as baby boomers aren?t retiring so much as changing how they?re impacting their communities. Going to Hard Money Lenders or other financial pros is a great way for boomers to learn new investment skills for their golden years.

Texas plant had history of thefts, tampering

By Selam Gebrekidan and Joshua Schneyer

NEW YORK (Reuters) - The Texas fertilizer plant that exploded two weeks ago, killing 14 people and injuring about 200, was a repeat target of theft by intruders who tampered with tanks and caused the release of toxic chemicals, police records reviewed by Reuters show.

Police responded to at least 11 reports of burglaries and five separate ammonia leaks at West Fertilizer Co over the past 12 years, according to 911 dispatch logs and criminal offense reports Reuters obtained from the McLennan County Sheriff's office in Waco, Texas through an Open Records Request.

Some of the leaks, including one reported in October 2012, were linked to theft or interference with tank valves.

According to one 2002 crime report, a plant manager told police that intruders were stealing four to five gallons of anhydrous ammonia every three days. The liquid gas can be used to cook methamphetamine, the addictive and illicit stimulant.

In rural areas across the United States, the thriving meth trade has turned storage facilities like West Fertilizer Co and even unattended tanks in farm fields into frequent targets of theft, according to several government and fertilizer industry reports issued over the past 13 years.

(AP Photo/Charles Dharapak) less? ?

The cause of the April 17 blast at the plant in the town of West is still being probed, and investigators have offered no evidence that security breaches contributed to the deadly incident. There also is no indication that the explosion had anything to do with the theft of materials for drug making. Anhydrous ammonia has been ruled out as a cause because the four storage tanks remained intact after the blast, said Rachel Moreno, a spokeswoman for the Texas Fire Marshal's Office.

MANY LEADS

Investigators are pursuing about 100 leads, including a call to an arson hotline and a tip that there had been a fire on the property earlier on the day of the explosion, according to Moreno. Authorities have not said whether either tip was credible. About 80 investigators from various state and federal agencies are contributing to the probe. They hope to determine by May 10 what caused the explosion, Texas Fire Marshal Chris Connealy said at a state legislative hearing on Wednesday.

A spokesman for the U.S. Department of Homeland Security (DHS), one of several state and federal agencies that monitor security at chemical plants, declined to answer questions about the breaches of security at West Fertilizer Co. State investigators also declined to comment.

Thefts of anhydrous ammonia are common in McLennan County, where burglars siphon fertilizer from trailer tanks into five-gallon propane containers, said McLennan County Chief Deputy Sheriff Matt Cawthon, who took up the position in January.

After reviewing crime reports from the past 12 years and speaking to deputies who responded to some of the break-ins, Cawthon said security was clearly lax at the plant.

The perimeter was not fenced, and the facility had no burglar alarms or security guards, he said. "It was a hometown-like situation. Everybody trusts everybody."

Chemical safety experts said the recurrent security breaches at West Fertilizer are troubling because they suggest vulnerability to theft, leaks, fires or explosions. Apart from anhydrous ammonia, the company stored tons of ammonium nitrate, a fertilizer that can be used in bomb-making. No thefts of that substance were reported to police.

"Regardless of what triggered this specific event, the fact that there were lots of burglaries and that they were after ammonia clearly shows this plant was vulnerable to unwanted intruders or even a terrorist attack," said Sam Mannan, a chemical process safety expert at Texas A&M University, who has advised Dow Chemical and others on chemical security.

NEW LAW

Owners of West Fertilizer, responding through a representative, declined to answer questions about specific instances of theft or the level of security at the plant. The company has encouraged its employees to share "all they know" with investigators, said Daniel Keeney, a spokesman for the company.

The current owners of West Fertilizer are Donald Adair, 83, and Wanda Adair, 78, who bought it in 2004. Calls to a number listed for previous owner Emil Plasek were not returned.

In a 2006 permit application with the Texas Commission on Environmental Quality (TCEQ), the company reported it would protect ammonia tanks against theft or tampering and conduct daily equipment inspections. A TCEQ spokesman would not comment about security measures. He said the agency's responsibility is to regulate emissions from the plant, not to oversee security.

Documents from the Texas Department of State Health Services show the West plant was storing 540,000 pounds of ammonium nitrate and 54,000 pounds of anhydrous ammonia in 2012. Ammonium nitrate was among the ingredients in the bomb used by Timothy McVeigh to blow up the Oklahoma City federal building in 1995, killing 168 people.

After that bombing, Congress passed a law requiring facilities that store large amounts of the chemical to report to the DHS and work with the agency to ensure proper security measures are in place to keep it out of criminal hands and protect against such attacks.

West Fertilizer did not report to DHS, despite storing hundreds of times more ammonium nitrate than the amount that would require it do so. Companies are required to report if they store at least 2,000 pounds of fertilizer-grade ammonium nitrate, or 400 pounds of the substance when it's combined with combustible material.

A 2005 U.S. Centers for Disease Control and Prevention (CDC) study identified hundreds of cases in 16 states where anhydrous ammonia was stolen for use in meth production. Some illegal labs mix anhydrous ammonia with ephedrine or pseudoephedrine and sodium or lithium to make methamphetamine, the U.S. Department of Justice reported in 2001.

In dozens of instances, the CDC said, the thefts by meth makers siphoning ammonia from tanks caused injuries or forced evacuations because gas was released into the environment. However, cases of ammonia theft have become less frequent since 2006, when new laws restricted the sale of pseudoephedrine, which is found in some common cold drug remedies, according to The Fertilizer Institute, an industry association.

Police records show West Fertilizer began complaining of repeated thefts from the facility in June 2001, when burglars stole 150 pounds of anhydrous ammonia from storage tanks three nights in a row. Nearly a year later, a plant manager told police that thieves were siphoning four-to-five gallons of the liquefied fertilizer every three days.

Randy Plemons, who was chief deputy sheriff during the years when the thefts occurred, declined to discuss specifics of his agency's response to the repeated break-ins.

"Whenever we were notified of the burglaries and thefts we responded to those," he said. "I can't speak to every offense."

Company owners downplayed security risks in documents submitted to the Texas Commission on Environmental Quality in 2006, saying thefts had dropped to zero over the preceding 20 months as meth makers now had found a substitute for anhydrous ammonia available at garden nurseries or major retailers.

VERY STRONG ODOR

Yet burglars and trespassers continued to target the facility. Following a series of break-ins in late 2008 and early 2009, including one where a trespasser visited pornographic websites on a secretary's computer, police told plant manager Ted Uptmore - who has worked at the company for decades -- to install a surveillance system. Later documents show the company complied. Uptmore did not respond to phone calls seeking comment for this story.

The last record of tampering was in October 2012, when a 911 caller reported an odor "so strong it can burn your eyes." The firm dispatched Cody Dragoo, an employee often sent after hours to shut leaking valves and look into break-ins. That night, he shut off the valve but reported it had been tampered with.

Two weeks ago, Dragoo, 50, was among those killed in the blast while responding to the fire.

News from the Front in War on Cancer--Mission Not Accomplished

Janet Rowley noticed something odd about the glowing chromosomes revealed by her microscope. It was the early 1970s, the first years of the so-called "war on cancer," and she was using a new staining technique to examine cells from patients with chronic myelogenous leukemia (CML), a cancer of the blood that was almost always fatal. The technique highlighted bands within the chromosomes, and she could see an extra piece on the end of chromosome 9. That fragment was nearly the same size as a "missing" chunk of chromosome 22 that other researchers had detected a decade earlier. To Rowley, it looked as if the tips of these two chromosomes had swapped places, or translocated. During the next few years she found two other cases of chromosomal translocation in different forms of leukemia. The finds forever changed the way scientists thought about cancer. Shuffled chromosomes in leukemia established that broken, scrambled and messed-up genes cause cancer. The genetic code details when cells should grow, divide and eventually die. Cancer is a disease of misinformation?cells ignore the rules, growing despite multiple molecular signals telling them to stop and invading other tissues because they no longer respond to biological messages to stay put or even destroy themselves. In the past four decades scientists have identified thousands of genetic mistakes that either cause cancer or boost the risk of developing it. The effects of these typos are sometimes dramatic?the gene variants BRCA1 and BRCA2 can boost women's lifetime risk of developing breast cancer from 12 percent to 60 percent. Some errors are found only in cancer cells themselves; other changes can be passed from generation to generation. The latter are the mistakes that may be passed down and boost the risk of developing cancer?this is the inherited genetic risk, or the reason that people with a familial history of a disease may want to get tested earlier or more often. As researchers uncover more genetic mistakes and delve deeper into the human genome, it may be possible to pin down the exact probabilities conferred by inherited genetic risk. If clinicians could scan a healthy person's genes for variations that explain their probability of developing cancer, perhaps they could prevent or catch the disease before it became a problem: Spit into this vial and the doctor will tell you what will ail you in 20 years. Despite the plummeting cost of DNA sequencing technology, much of the information is a jumble of alphabet soup. Science can figure out what gene variants and markers a person has, but they can't tell exactly what it means for his or her health. It will take researchers years to untangle the genetics of cancer. Even large steps, heralded as a major advances, answer few questions and pose many more. This spring, a massive international collaboration doubled the number of known genetic regions associated with the risk of breast, prostate or ovarian cancers. The genetic markers are signpost that researchers can follow to better understand the biology of these cancers. Only a few of the 74 newly identified markers are shared by more than one type of cancer, underscoring cancer's complexity. Yet exactly how the findings can inform public health recommendations remains to be discovered. Each marker is associated with small modifications of risk, but the effects add up. The findings could lead to more accurate cancer screening and hint at ways cancers could be caught before the disease becomes aggressive. Only further study, however, will show where to draw the lines between risk percentages that tell patients "not to worry" or "get tested now." Reams of data
The impressive number of hits in the new work stems from the size of the research effort: 160 institutions around the world analyzed a pool of more than 200,000 individuals' genetic sequences. The international project is called the Collaborative Oncological Gene-environment Study (COGS). To find the dozens of new cancer risk regions, researchers combed the pooled genetic information for variations called single-nucleotide polymorphisms (SNPs). A SNP is change in a single letter of the DNA code, likely introduced as a "typo" during gene replication. If such a change happens within a gene, it can affect the structure of proteins. If it falls within a stretch of DNA that regulates genes, it can affect the amount of protein a cell produces. The COGS researchers put 211,000 SNPs of interest, which were previously identified in other studies, on a custom-made DNA array that looks a bit like a computer chip. Then they used the chip to scan the pooled genetic information to look for differences between people who had cancer and those who did not. If a particular SNP popped up more often in the group of people who had cancer, that SNP could be linked to increased risk for that cancer. Most of the SNPs the cancer teams identified are specific to one of the three cancers, but 17 are shared risk factors for all three. The new SNPs, combined with 75 previously known markers, explain a proportion of inherited genetic risk for these cancers: 28 percent for breast, 4 percent for ovarian and 30 percent for prostate cancer. The research was published as a collection of 13 papers in April in Nature Genetics, Nature Communications, PLoS Genetics, The American Journal of Human Genetics, and Human Molecular Genetics (Scientific American is part of Nature Publishing Group). Comparing genomes to uncover SNPs of interest is one way that researchers dig down to find the genetic basis of complex diseases. "We get little bits that we put together," says Stephen Chanock, chief of the Laboratory of Translation Genomics at the National Cancer Institute. Chanock was involved in several of the new studies. Complex diseases such as cancer spring from many gene variants that all contribute to the disease. These studies are helping researchers fill in the list of risky genetic markers. "What is emerging is the complicated genetic architecture of different diseases," he says. Following the signs
Rowley's swapped chromosomes eventually led researchers to find a way to treat CML. Now patients can take a pill that jams a monkey wrench into a process vital to the cancer's development. The drug, called imatinib (first marketed as Gleevec in the U.S.), often grants patients a normal life expectancy with minimal side effects. Few cancer treatments have met this high bar, but researchers still comb the genome for cancer's fingerprints and clues to what might stop the disease. Indeed, the COGS findings provide signposts for future research. For example, a handful of SNPs associated with prostate cancer risk fall within genes important for the binding of a cell to a surface. That surface could be another cell to facilitate communication or create a barrier through which pathogens cannot pass. Cell?cell adhesion is important for immune response and is also involved in tumor metastasis?tumor cells use cell adhesion to stick to a new location in the body. Understanding the mechanisms for cell?cell adhesion may offer insights for new treatments. In a number of regions the SNPs are involved in more than one type of cancer cluster. "In some cases we are beginning to understand why that is," said Doug Easton, a professor at the University of Cambridge and the lead author of the main breast cancer paper at a press conference before the papers were published. One of the COGS papers honed in on a genetic region that helps control the length of telomeres, which are protective caps on the end of DNA strands. The so-called TERT locus harbors SNPs relevant to both breast and ovarian cancer risk, making it a prime candidate for further study. The next step for the international cancer teams is an even larger study with a new chip called OncoChip, made by Signature Genomics. They plan to screen 600,000 SNPs of interest to see if they are involved five malignancies?ovarian, breast and prostate as well as colorectal and lung cancers. The larger numbers will give the researchers more statistical power to uncover less common gene variants. In addition researchers will map the already discovered variants to figure out which genes and biochemical pathways are involved. Studies of gene function are critical to characterize cancer biology, says Mathieu Lupien, a scientist at the Ontario Cancer Institute and assistant professor at the University of Toronto who was not involved in COGS. "Now we can move forward and understand why it is those genetic defects promote cancer," he says. Weighing the risks
Genetic markers may lead to better treatments, but researchers also hope to catch cancer before it starts. Clinicians already use cancer-risk calculators to group people into high- and low-risk categories based on lifestyle choices, environment and family history. The new SNPs could be additional indicators that make the stratification more accurate and efficient. High-risk groups could get targeted recommendations for avoiding risky behaviors or whether to get screened for a type of cancer. Currently, cancer screening is saddled with a lot of false positives, which means people who do not have cancer are told they are positive. Such results lead to unnecessary and even dangerous procedures?not to mention the anxiety felt by those who believe they have a potentially life-threatening disease. For example, screening for prostate, lung, colorectal and ovarian cancers in 68,436 people over a period of three years led to a least one false positive for 60 percent of men and 49 percent of women. Another study found that follow-up procedures (such as a biopsy) after a false positive cost an average of $1,024 for women and $1,171 for men. The challenge is figuring out where to draw the line for high-risk, says Ros Eeles, a professor of oncogenetics at the Institute of Cancer Research in London and one of the principal investigators involved in the main prostate cancer paper. "We could do the test and give a risk profile, but we don't know what you should do when you have the information," she says. Studies that retroactively profile genetic risk markers in patients could reveal where the lines should fall and what interventions are most effective. "We're not to the point of being able to predict an individual's risk," says Joe Gray, a professor at Oregon Health & Science University's Knight Cancer Institute and not involved in the COGS studies. A more thorough understanding of risk factors and better cancer screening could lead to a future where doctors can "prevent people from having cancer we don't know how to treat," he says. More information about how different genetic variants contribute to risk of disease could help refine the definition of high-risk groups. A well-tested SNP profile could sort out individuals at the top of the spectrum, where the benefits of screening would outweigh the risks. Once the genetic risk is understood, public health professionals can employ the same communication strategies used to counsel people about heart disease risk. "We do [stratified screening] all the time with cardiovascular risk," says Hilary Burton, director of the PHG Foundation based in England. Right now the evidence on breast cancer screening is "finely balanced between benefits and harm," she says. The newly identified SNPs can help tip the balance for some carefully identified individuals. The vision the researchers outline could be in the not-too-distant future. People in their 40s today might see safer, stratified risk screening for some cancers within their lifetimes, Cambridge?s Easton said in a press conference. Still, before all patients can receive the benefits of safe screening, researchers will need to address a gap common to current genome-based discoveries: The 200,000 people in the COGS pool are largely of European descent and live Australia, North America and Europe. Whereas the consortium did find some risk markers specific to people of Asian descent, other genetic groups such as African and indigenous populations in the Americas and Australia are underrepresented. "We are still very much in the discovery mode," Chanock says. Decades after uncovering the genetic basis of cancer, that is a sobering statement.

Traktor DJ gets remixed for iPhone, brings big features to small pockets (video)

Traktor DJ for iPad showed us what can be done when you resist the urge to simply shrink your existing software or just slide it under a touch interface. Since its iOS debut, the folk at Native Instruments have spent the last couple of months cautiously considering how best to transplant the same waveform-based interface over to the iPhone. Today, you can find out. You get everything you find in the iPad version, like three band EQ, filters, hot cues and effects --along with the same key, tempo and timbre matching utilities, plus library sharing with the full-fat desktop version. The UI isn't the only thing getting downsized, either: this iPhone-friendly version costs just $4.99 (compared to $20 on the iPad). That should leave enough change to drop a few on party rock anthems.

The World's Toughest Material Is Built of Knots

A scientist from the University of Trento in Italy claims to have made the world's toughest material. But this isn't some kind of exotic super material?it's just made from strands of fiber with knots tied in them.

The material, created by Nicola Pugno, is formed from strands of Endumax polymer fiber with a simple slip knot tied into them. For those who missed out on a youth in scouting, a slip knot's incredibly simple: it's just a loop of rope passed through a bight?that's a u-shaped section of the same rope?and you probably tie one without thinking about it. But how the hell does that give rise to a super-tough material?

Before diving into exactly how it works, it's worth pointing out what toughness actually is. Crucially, it's not strength?that's a measure of how much force a material can handle before it breaks. Toughness is instead a measure of how much energy a material can absorb So, glass is strong, not tough; rubber is tough, not strong; steel is a bit of both. For some perspective, kevlar is considered incredibly tough, and can handle 80 joules per gram before breaking.

So, Pugno took those Endumax fibers?which usually exhibit a toughness of 44 joules per gram without a knot?and tied his slip knots. Then he loaded them up, and found that they could absorb an astronomical quantity of energy before breaking. The reason? Well, when loaded, the knot dissipates large quantities of energy through friction as it's pulled. Once the knot slips open, the fiber fails?but by that point it's absorbed 1,070 joules of energy per gram.

For comparison, that's more than the theoretical values calculated for graphene, which we think can only withstand 1,000 joules per gram. So Pugno's material could?could?be the toughest material in the world. He also theorizes that a knotted thread of graphene could absorb 100,000 joules per gram, which is just insane.

But easy there, tiger. There are caveats. First, it's not clear how a single fiber with a knot tied in it translates to a real, practical piece of material: a sheet of kevlar contains thousands of fibers, each of which would need knots tied in them somehow. Second, this work is preliminary?it's not yet appeared in a peer-reviewed journal?so it's not clear that it's 100 percent reproducible.

But hey, let's assume it is, and that manufacturing techniques could cope. If that's the case, we have something pretty special on our hands here. [arXiv via Extreme Tech]

Massive Mobile Advertising Ecosystem - Business Insider

We are in the post-PC era, and soon billions of consumers will be carrying around Internet-connected mobile devices for up to 16 hours a day.?Mobile audiences have exploded as a result.

Mobile advertising should be a bonanza, similar to online advertising a decade ago. However, it has been a bit slow off the ground, and its growth trajectory is not clear cut.

In a recent report from?BI?Intelligence?on the mobile advertising ecosystem, we?explain the complexities and fractures, and examine the central and dynamic roles played by mobile ad networks, demand side platforms, mobile ad exchanges, real-time bidding, agencies, brands, and new companies hoping to upend the traditional banner ad.

Here's the dynamics surrounding the mobile advertising ecosystem:

• Mobile advertising is relatively tiny:?U.S. mobile ad revenue was $1.2 billion last year, a tiny fraction of overall U.S. ad spend.?And most "mobile ads" were simply search and display ads viewed on mobile.??According to BI Intelligence estimates, mobile advertising is on track to hit $3.2 billion this year.?
• Why??Mobile CPMS are low, and ads are oftentimes intrusive.?Ad spending has therefore not caught up with time spent on mobile.?These will remain significant challenges to mobile ads.
• Also, the mobile ad ecosystem is very complex:?The mobile ad ecosystem is not as strictly delineated as the desktop ecosystem.?In mobile advertising, the rules of the road change with different combinations of device, wireless operator, and operating system.
• And there are few shared protocols or standards: Mobile lacks the technical consensus that enables ad targeting, delivery, and measurement to work fairly seamlessly across the desktop world.?As the mobile ad industry matures it will likely become more streamlined and simple, but for now there are innumerable actors interacting with one another and attempting to find a niche.
• The display ad category presents a dynamic and complicated future:?Google?dominated the paid search category, which accounted for?62 percent of mobile global ad spend last year. But, mobile ad networks, demand side platforms, mobile ad exchanges are all part of a dynamic ecosystem that is constantly evolving and trying to grow non-search mobile related advertising. New companies are also testing out and finding some success with mobile native ad formats.?
