Photonic crystals used to make optical RAM

This photonic lattice created at Sandia National Laboratories acts like a crystal in guiding light because of its tiny, regularly placed silicon “logs.” Japanese researchers have shown how to use photonic crystals like this as optical RAM. Sandia National Labs Most high-speed networking is done using optical fibers. The hardware on each end of these fibers has to convert the optical signals to electronic ones in order to figure out a packet’s destination and will often return it to optical form before sending it on toward its destination. Researchers at the Japanese telecom NTT find all that converting a bit wasteful and are working on ways to avoid it. They’ve recently published a paper that includes a description of a working 115-bit optical Random Access Memory device, made of a carefully structured series of photonic crystals, each of which can store light of a different wavelength. Photonic crystals are made of layered semiconductors, with the precise structure (the thickness and spacing of the layers) determining how they interact with light—it’s possible to make photonic crystals that selectively block or transmit a narrow frequency range.

Prosecutors: ex-LulzSec hacker “Sabu” helped authorities stop 300+ cyberattacks

The much delayed sentencing of former LulzSec hacker-turned-FBI informant Hector “Sabu” Monsegur is set to take place next week. But before any decisions are made public, new court documents  (PDF) show Monsegur has helped the feds disrupt more than 300 attacks against targets ranging from the US military to NASA, Congress to private companies. “The amount of loss prevented by Monsegur’s actions is difficult to fully quantify, but even a conservative estimate would yield a loss prevention figure in the millions of dollars,” the document stated. The tale of Sabu’s arrest and LulzSec’s fall: FBI still needs Hector “Sabu” Monsegur, sentencing delayed (again) “Literally” the day he was arrested, hacker “Sabu” helped the FBI LulzSec leader “Sabu” worked with FBI since last summer FBI names, arrests Anon who infiltrated its secret conference call Inside the hacking of Stratfor: the FBI’s case against Antisec member Anarchaos All the latest on the unmasking of LulzSec leader “Sabu,” arrests Stakeout: how the FBI tracked and busted a Chicago Anon Doxed: how Sabu was outed by former Anons long before his arrest Anonymous attacks security firm as revenge for LulzSec arrests “Everything incriminating has been burned”: Anons fight panic after Sabu betrayal Monsegur assisted in high-profile hacks of security firm HBGary and others as a member of LulzSec, a sect of Anonymous. He began cooperating with the FBI in June 2011 after his arrest at the Jacob Riis public housing complex in New York City. His work for the feds began immediately . Eventually Monsegur  helped the government build cases  against numerous Anonymous hackers, including Stratfor hacker Jeremy Hammond . He apparently also assisted the government in its  investigation of Wikileaks . According to the  New York Times , prosecutors filed the new documents because they are asking Judge Loretta A. Preska for leniency in light of Monsegur’s “extraordinary cooperation.” Sentencing in Monsegur’s case is currently scheduled for Tuesday in a Federal District Court in Manhattan. But while some of the other hackers in the LulzSec saga have faced steep penalties (for example, Hammond is serving a 10-year sentence), the government has asked for Monsegur to only be sentenced to time served— just seven months .

Airbnb gives up customer data to NY attorney general

Airbnb Home renting company Airbnb announced Wednesday that under pressure from the New York attorney general’s office, it will hand over the anonymized personal data of its New York hosts to the state. New York Attorney General Eric Schneiderman subpoenaed three years’ worth of data in 2013 in an effort to suss out whether Airbnb users are running “illegal hotels” and to determine if Airbnb’s business model and platform comply with the law. Schneiderman stated his suspicions in April that Airbnb hosts in New York operate residences or parts of their homes like hotels—but without the fire, safety, and tax regulations normally applied to hotels. Airbnb hosts could also be in violation of a 2010 law that prohibits New Yorkers from renting entire apartments for less than 29 consecutive days. Schneiderman claimed that Airbnb sells itself to investors as a hotel network, but it attempts to keep that pitch out of the public sphere for fear of incurring legal hotel status. The New York Supreme Court rejected Schneiderman’s subpoena request on May 13, “but the judge’s ruling also made it clear that he would accept a new, narrower subpoena and require Airbnb to turn over personal information about hosts if the Attorney General’s Office made some changes to their demands,” wrote Airbnb in its blog post Wednesday.

California approves test of self-driving cars on public roads

Terrence Lui On Tuesday, the California Department of Motor Vehicles (DMV)  officially approved rules to allow the testing of autonomous vehicles on public roads. The rules will take effect September 16, 2014. The move has been a long time coming , with the DMV promising back in December 2013 that it would post regulations for public use of self-driving cars  and then holding a public hearing in January to address concerns about them. These new rules will set a statewide standard for all manufacturers. (Although Google has been running pilot programs in Mountain View and elsewhere, it’s not the only company pursuing an automated vehicle—Nvidia told Ars last week that Audi has plans to incorporate a “cruise control for stop-and-go traffic” feature in one of its cars come 2015.) Bryant Walker Smith, a fellow at the Center for Automotive Research at Stanford (CARS), told Ars that the new rules could change how manufacturers proceed with their testing. “The DMV has a really, really difficult task, and I was impressed with the thoughtfulness of their approach,” he said. “I would say that anyone who is reading these documents will have to read very closely.” Read 6 remaining paragraphs | Comments

Wi-Fi networks are wasting a gigabit—but multi-user beamforming will save the day

Aurich Lawson Wi-Fi equipment based on the new 802.11ac standard—often called Gigabit Wi-Fi —has been on the market for nearly two years. These products offer greater bandwidth and other improvements over gear based on the older 802.11n specification, but they don’t implement one of the most impressive features of 11ac. It was simply too complicated to deploy all the upgrades at once, hardware makers say. As a result, 11ac networks actually waste a lot of capacity when serving devices like smartphones and tablets. This shortcoming should be fixed over the next year with new networking equipment and upgrades to end-user devices. Once everything is in place, Wi-Fi networks will be better able to serve lots of devices at once, particularly the mobile devices that every single person in the US seemingly has in his or her hands every minute of the day.The soon-to-be-deployed technology is called MU-MIMO (multi-user, multiple-input and multiple-output), which is like a wireless “switch” that sends different data to different receivers at the same time. It’s powered by multi-user beamforming, an improvement over the single-user beamforming found in first-generation 11ac products. MU-MIMO will let wireless access points send data streams of up to 433Mbps to at least three users simultaneously, for a total of 1.3Gbps or more. First-generation 11ac equipment without MU-MIMO could send those streams of data simultaneously, but only to one device—and only if that device was capable of receiving multiple streams. Many computers could handle the influx of data, but smartphones and tablets generally couldn’t. That meant they could only receive one stream (occasionally two) because of power limitations.

Urine and the bladder are not sterile, contain bacteria

Gray’s Anatomy No, urine is not sterile, according to a study presented this week by researchers from the Stritch School of Medicine at Loyola University. Instead, the bodily excretion does contain a diverse array of bacteria that can vary depending on bladder condition. Up until now, the types of bacteria present have been hard to detect because they don’t grow in urine cultures. That urine is not sterile is not actually news; the same medical school reported findings in 2012  suggesting that urine can contain bacteria when drawn directly from the bladder. But the study may surprise many due to the deeply entrenched belief , even in the medical community, that urine is bacteria-free and thus safe to use in a number of activities, from drinking to rinsing wounds in a pinch. A commonly traded rule of thumb is that, while the initial part of a stream of urine contains bacteria washed from the urethra, the “mid-stream” is safely sterile. This is not so, or at least it’s not entirely reliable information. The two studies, from 2013 and 2012, looked only at samples from women. The 2013 study compared samples from women with and without overactive bladder disorder (OAB) and found different types of bacteria in both types of samples, including Streptococcus and Staphylococcus. The authors of the study suggested that the presence of certain types of bacteria in women with OAB could be causing their symptoms, and treating their presence could help with their condition.

Intel CEO: Delayed next-gen Broadwell CPUs will be here for holidays

One of the few looks we’ve gotten at a Broadwell CPU so far. Intel New CPUs and chipsets from Intel normally go hand-in-hand, but earlier this month when the company announced its 9-series chipsets , all we got was a slightly faster clock speed bump to Haswell . News of truly new CPUs based on the upcoming “Broadwell” architecture was nowhere to be found, and we’ve generally heard very little about Broadwell aside from an announcement of a  delay  into the second half of 2014. There are many months in the second half of 2014, but Intel CEO Bryan Krzanich got a little more specific in a statement to Reuters today . “I can guarantee for holiday, and not at the last second of holiday,” said Krzanich. “Back to school—that’s a tight one. Back to school you have to really have it on-shelf in July, August. That’s going to be tough.” This means we’ll most likely see Broadwell chips (and, more importantly, new devices from OEMs that can use Broadwell chips) sometime between September and early December.

“Stains of deceitfulness”: Inside the US government’s war on tech support scammers

Aurich Lawson / PCCare247 Sitting in front of her PC, the phone in her hand connected to a tech support company half a world away, Sheryl Novick was about to get scammed. The company she had reached, PCCare247, was based in India but had built a lucrative business advertising over the Internet to Americans, encouraging them to call for tech support. After glimpsing something odd on her computer, Novick did so. “I saw some sort of pop-up and I don’t know if there’s a problem,” she told a PCCare247 tech named Yakeen. He offered to check the “management part” of her computer for possible problems. Read 61 remaining paragraphs | Comments

Shocker: Cable TV prices went up four times the rate of inflation

The Federal Communications Commission today issued a report on average cable TV prices in the US , and to the surprise of no one, it turns out they went up a lot. “Basic cable service prices increased by 6.5 percent [to $22.63] for the 12 months ending January 1, 2013. Expanded basic cable prices increased by 5.1 percent [to $64.41] for those 12 months, and at a compound average annual rate of 6.1 percent over the 18-year period from 1995-2013,” the FCC said. The basic cable increase was four times the rate of inflation as measured by the Consumer Price Index (CPI) for the 12-month period, and substantially above inflation for the 1995-2013 measurement.

Apple releases OS X 10.9.3 with improved 4K support, restored USB sync

Fire up your updaters—there’s a slightly newer and better version of OS X in town. Andrew Cunningham Following its usual months-long testing process, Apple released OS X version 10.9.3 to the general public today. The third major update to the operating system provides the usual blend of security patches, bug fixes, new (and restored) features, and future-proofing enhancements. As was discovered shortly after the first 10.9.3 beta was released, the new update improves 4K display support specifically on the 2013 Mac Pro and the 15-inch 2013 Retina MacBook Pro. When those computers are connected to a 4K display, they should be able to display images in OS X’s HiDPI “Retina” scaling mode by default, and they should support the faster 60Hz refresh rate on compatible monitors. “Retina” mode will make on-screen images larger and sharper, while the refresh rate increase will make UI animations, videos, and games look and feel smoother and more responsive (provided the GPU is capable of rendering them at 60 frames per second in the first place). Though the 13-inch 2013 Retina MacBook Pro has the hardware it needs to drive similar 4K displays—a Thunderbolt 2 port with DisplayPort 1.2 support and one of Intel’s Iris 5100 GPUs—that specific computer is not mentioned in Apple’s release notes.
