Static Electricity Defies Simple Explanation

sciencehabit writes: “If you’ve ever wiggled a balloon against your hair, you know that rubbing together two different materials can generate static electricity. But rubbing bits of the same material can create static, too. Now, researchers have shot down a decades-old idea of how that same-stuff static comes about (study). ‘[The researchers] mixed grains of insulating zirconium dioxide-silicate with diameters of 251 micrometers and 326 micrometers and dropped them through a horizontal electric field, which pushed positively charged particles one way and negatively charged particles the other. They tracked tens of thousands of particles—by dropping an $85, 000 high-speed camera alongside them. Sure enough, the smaller ones tended to be charged negatively and the larger ones positively, each accumulating 2 million charges on average. Then the researchers probed whether those charges could come from electrons already trapped on the grains’ surfaces. They gently heated fresh grains to liberate the trapped electrons and let them “relax” back into less energetic states. As an electron undergoes such a transition, it emits a photon. So by counting photons, the researchers could tally the trapped electrons. “It’s pretty amazing to me that they count every electron on a particle, ” Shinbrot says. The tally showed that the beads start out with far too few trapped electrons to explain the static buildup, Jaeger says.'” Read more of this story at Slashdot.

Can Thunderbolt Survive USB SuperSpeed+?

Lucas123 writes: “The USB SuperSpeed+ spec (a.k.a. v3.1) offers up to 10Gbps throughput. Combine that with USB’s new C-Type Connector, the specification for which is expected out in July, and users will have a symmetrical cable and plug just like Thunderbolt but that will enable up to 100 watts of power depending on the cable version. So where does that leave Thunderbolt, Intel’s other hardware interconnect? According to some analysts, Thunderbolt withers or remains a niche technology supported almost exclusively by Apple. Even as Thunderbolt 2 offers twice the throughput (on paper) as USB 3.1, or up to 20Gbps, USB SuperSpeed+ is expected to scale past 40Gbps in coming years. ‘USB’s installed base is in the billions. Thunderbolt’s biggest problem is a relatively small installed base, in the tens of millions. Adding a higher data throughput, and a more expensive option, is unlikely to change that, ‘ said Brian O’Rourke, a principal analyst covering wired interfaces at IHS.” Read more of this story at Slashdot.

Physician Operates On Server, Costs His Hospital $4.8 Million

Hugh Pickens DOT Com (2995471) writes “Jaikumar Vijayan reports at Computerworld that a physician at Columbia University Medical Center (CU) attempted to “deactivate” a personally owned computer from a hospital network segment that contained sensitive patient health information, creating an inadvertent data leak that is going to cost the hospital $4.8 million to settle with the U.S. Department of Health and Human Services (HHS). The error left patient status, vital signs, laboratory results, medication information, and other sensitive data on about 6, 800 individuals accessible to all via the Web. The breach was discovered after the hospital received a complaint from an individual who discovered personal health information about his deceased partner on the Web. An investigation by the HHS Office for Civil Rights (OCR) found that neither Columbia University nor New York Presbyterian Hospital, who operated the network jointly, had implemented adequate security protections, or undertook a risk analysis or audit to identify the location of sensitive patient health information on the joint network. “For more than three years, we have been cooperating with HHS by voluntarily providing information about the incident in question, ” say the hospitals. “We also have continually strengthened our safeguards to enhance our information systems and processes, and will continue to do so under the terms of the agreement with HHS.” HHS has also extracted settlements from several other healthcare entities over the past two years as it beefs up the effort to crack down on HIPAA violations. In April, it reached a $2 million settlement with with Concentra Health Services and QCA Health Plan. Both organizations reported losing laptops containing unencrypted patient data.” Read more of this story at Slashdot.

Single Gene Can Boost IQ By Six Points

ananyo (2519492) writes “People are living longer, which is good. But old age often brings a decline in mental faculties and many researchers are looking for ways to slow or halt such decline. One group doing so is led by Dena Dubal of the University of California, San Francisco, and Lennart Mucke of the Gladstone Institutes, also in San Francisco. Dr Dubal and Dr Mucke have been studying the role in ageing of klotho, a protein encoded by a gene called KL. A particular version of this gene, KL-VS, promotes longevity. One way it does so is by reducing age-related heart disease. Dr Dubal and Dr Mucke wondered if it might have similar powers over age-related cognitive decline. What they found was startling. KL-VS did not curb decline, but it did boost cognitive faculties regardless of a person’s age by the equivalent of about six IQ points. If this result, just published in Cell Reports, is confirmed, KL-VS will be the most important genetic agent of non-pathological variation in intelligence yet discovered.” Read more of this story at Slashdot.

Finally, Hi-Def Streaming Video of the ISS’s View of Earth

An anonymous reader writes with a snippet from ExtremeTech: “After being continuously inhabited for more than 13 years, it is finally possible to log into Ustream and watch the Earth spinning on its axis in glorious HD. This video feed [embedded at ExtremeTech] comes from from four high-definition cameras, delivered by last month’s SpaceX CRS-3 resupply mission, that are attached to the outside of the International Space Station. You can open up the Ustream page at any time, and as long as it isn’t night time aboard the ISS, you’ll be treated to a beautiful view of the Earth from around 250 miles (400 km) up.” Read more of this story at Slashdot.

Meet Ununseptium, Best Contender Yet For Element 117

From Motherboard comes this description of what may turns out to be the newest entry on the periodic table, newly synthesized element 117, created by researchers at the GSI Helmholtz Centre for Heavy Ion Research of Darmstadt, Germany, and described in results published this week in Physical Review Letters. From the article: “Element 117 has been temporarily given the very literal name ununseptium (one-one-seven in Latin), and will only honored with a real name once the the International Union of Pure and Applied Physics and Chemistry (IUPAPC) confirms its synthesis at the GSI accelerator. Ununseptium is 40 percent heavier than lead, making it on par with the heaviest atoms ever observed. … Its properties seem to confirm that the existence of the so-called “island of stability”—a theory suggesting that the half-lives of superheavy isotopes will lengthen as their atomic numbers increase further away from uranium. Any element with an atomic number greater than 103 is considered superheavy (or in the ‘transactinide class, ‘ if you prefer the scientific jargon). Transactinides can only be observed artificially in a laboratory, and synthesizing them is no easy task.” Note: that “real name” process isn’t a mere formality; just a few years ago, another attempt to synthesize a 117th element looked promising enough to be declared done, but could not be confirmed with the IUPAPC’s tests.

Stanford Bioengineers Develop ‘Neurocore’ Chips 9,000 Times Faster Than a PC

kelk1 sends this article from the Stanford News Service: “Stanford bioengineers have developed faster, more energy-efficient microchips based on the human brain – 9, 000 times faster and using significantly less power than a typical PC (abstract). Kwabena Boahen and his team have developed Neurogrid, a circuit board consisting of 16 custom-designed ‘Neurocore’ chips. Together these 16 chips can simulate 1 million neurons and billions of synaptic connections. The team designed these chips with power efficiency in mind. Their strategy was to enable certain synapses to share hardware circuits. … But much work lies ahead. Each of the current million-neuron Neurogrid circuit boards cost about $40, 000. (…) Neurogrid is based on 16 Neurocores, each of which supports 65, 536 neurons. Those chips were made using 15-year-old fabrication technologies. By switching to modern manufacturing processes and fabricating the chips in large volumes, he could cut a Neurocore’s cost 100-fold – suggesting a million-neuron board for $400 a copy.” Read more of this story at Slashdot.

AMD Beema and Mullins Low Power 2014 APUs Tested, Faster Than Bay Trail

MojoKid (1002251) writes “AMD has just announced their upcoming mainstream, low-power APUs (Accelerated Processing Units), codenames Beema and Mullins. These APUs are the successors to last year’s Temash and Kabini APUs, which powered an array of small form factor and mobile platforms. Beema and Mullins are based on the same piece of silicon, but will target different market segments. Beema is the mainstream part that will find its way into affordable notebook, small form factor systems, and mobile devices. Mullins, however, is a much lower-power derivative, designed for tablets and convertible systems. They are full SoCs with on-die memory controllers, PCI Express, SATA, and USB connectivity, and a host of other IO blocks. AMD is announcing four Beema-based mainstream APUs today, with TDPs ranging from 10W – 15W. There are three Mullins-based products being announced, two quad-cores and a dual-core. The top of the line-up is the A10 Micro-6700T. It’s a quad-core chip, with a max clock speed of 2.2GHz, 2MB of L2, and a TDP of only 4.5W. In the benchmarks, the A10-6700T quad core is actually able to surpass Intel’s Bay Trail Atom platform pretty easily across a number of tests, especially gaming and graphics.” Read more of this story at Slashdot.
