Scientists May Have Found Molecular Gatekeeper Of Long-Term Memory

hackingbear writes: While the general steps of forming a long-term memory are clear, the details, such as how exactly the molecular signals get shuttled to the command center, which generally has tight security, are unclear. A new study, led by neuroscientist Yi Zhong of Tsinghua University in Beijing, may finally have that answer. In the tiny minds of fruit flies, a protein called importin-7 acts to shuttle the memory-triggering signal into the nucleus with its top-level clearance to the restricted area, researchers report in the Proceedings of the National Academy of Sciences. With genetic tweaking, the researchers dialed up and down the amount of importin-7 in the flies and then put them through the memory training and test. They found that cranking up levels of the shuttle protein strengthened the long-term memories of the flies, while turning it off weakened their memory. “The current work confirms that [importin-7] is indeed critical at the behavioral level in mediating [long-term memory] consolidation, ” the authors concluded.

DoD Announces New Bug Bounty Program Called Hack the Pentagon

Quince alPillan writes: Announcing what it calls “the first cyber bug bounty program in the history of the federal government, ” the Department of Defense says it’s inviting vetted hackers to test the security of its web pages and networks. Vetted hackers will need to pass a background check and will be attacking a predetermined system that is not a part of critical operations. This program is being put together by the Digital Defense Service, launched last fall. Read more of this story at Slashdot.

Israeli Troops Who Relied On Waze Blundered Into Deadly Palestinian Firefight

An anonymous reader writes: Israeli forces mounted a rescue mission in a Palestinian neighborhood after gun battles erupted when two soldiers mistakenly entered the area because of an error on a satellite navigation app, Israeli authorities said Tuesday.The clashes late Monday in the Qalandiya refugee camp outside Jerusalem left at least one Palestinian dead and 10 injured, one seriously. According to initial Israeli reports, the two soldiers said they had been using Waze, a highly touted Israeli-invented navigation app bought more than two years ago by Google. The smartphone app, which has a settings option to ‘avoid dangerous areas, ‘ relies on crowdsourcing to give users the fastest traffic routes. Read more of this story at Slashdot.

Scientists Achieve Perfect Efficiency For Water-Splitting Half-Reaction

Dthief writes: Splitting water is a two-step process, and in a new study, researchers have performed one of these steps (reduction) with 100% efficiency. The results shatter the previous record of 60% for hydrogen production with visible light, and emphasize that future research should focus on the other step (oxidation) in order to realize practical overall water splitting. The main application of splitting water into its components of oxygen and hydrogen is that the hydrogen can then be used to deliver energy to fuel cells for powering vehicles and electronic devices. The process involves exposing the water to a mass of platinum-tipped nanorods, with visible light driving the reaction. The 100% efficiency refers to the photon-to-hydrogen conversion efficiency, and it means that virtually all of the photons that reach the photocatalyst generate an electron, and every two electrons produce one H2 molecule. At 100% yield, the half-reaction produces about 100 H2 molecules per second (or one every 10 milliseconds) on each nanorod, and a typical sample contains about 600 trillion nanorods.

CompuLab Rolls out Fanless, High-End PCs With Unique Design

An anonymous reader writes: Israeli PC maker CompuLab has begun shipping the Airtop PC that allows assembling high-end PC components into a completely fanless design. Phoronix’s initial testing of the Airtop PC showed that it has a Core i7 5775C Broadwell processor, 16GB of RAM, 256GB SSD, and GeForce GTX 950 all while being fan-less thanks to the innovative design. The early results are quite positive for this uniquely designed PC but it comes at a cost premium of a fully-loaded system costing more than $2, 200 USD. Read more of this story at Slashdot.

Chinese ISPs Caught Injecting Ads And Malware In Their Network Traffic

Chinese Internet Service Providers (ISPs) have been caught red-handed for injecting advertisements as well as malware through their network traffic. Three Israeli researchers uncovered that the major Chinese-based ISPs named China Telecom and China Unicom, two of Asia’s largest network operators, have been engaged in an illegal practice of content injection in network traffic. Chinese ISPs had set up many proxy servers to pollute the client’s network traffic not only with insignificant advertisements but also malware links, in some cases, inside the websites they visit. If an Internet user tries to access a domain that resides under these Chinese ISPs, the forged packet redirects the user’s browser to parse the rogue network routes. As a result, the client’s legitimate traffic will be redirected to malicious sites/ads, benefiting the ISPs. Read more of this story at Slashdot.

Are CEOs Overpaid? Not Compared With College Presidents

schwit1 writes: For outrageous executive earnings, don’t look to Wall Street — look to academia. High pay for CEOs attracts annual attention and recitations about the immorality of capitalism, but when the focus is on average CEO pay, they make less than half the annual earnings of college presidents, according to CBS News. The average CEO earns $176, 840 annually, an amount that would make a university president into a pauper. In academia, college presidents earn $377, 261 annually. Americans outraged and indebted by high college costs will be quick to draw the parallel between a college president’s pay and their tuition bill. Correlation, though, doesn’t imply causation. College presidents aren’t always the highest-paid college employees — athletic coaches often earn more. Regardless, college presidents “are well into the 99th percentile of compensation for wage earners in the United States, ” Peter L. Hinrichs and Anne Chen noted for the Federal Reserve Bank of Cleveland. Read more of this story at Slashdot.

‘Moth Eye’ Graphene Breakthrough Could Create Indoor Solar Cells

A scientific breakthrough with the “wonder material” graphene has opened up the possibility of indoor solar cells that capture energy from indirect sunlight, as well as ambient energy from household devices. Researchers from the University of Surrey in the U.K. studied the eyes of moths to create sheets of graphene that they claim is the most light-absorbent material ever created. “We realized that the moth’s eye works in a particular way that traps electromagnetic waves very efficiently, ” Professor Ravi Silva, head of the Advanced Technology Institute at the University of Surrey, tells Newsweek. “As a result of our studies, we’ve been able to mimic the surface of a moth’s eye and create an amazingly thin, efficient, light-absorbent material made of graphene.” Read more of this story at Slashdot.

Google Unveils Neural Network With Ability To Determine Location of Any Image

schwit1 writes: Here’s a tricky task. Pick a photograph from the web at random. Now try to work out where it was taken using only the image itself. If the image shows a famous building or landmark, such as the Eiffel Tower or Niagara Falls, the task is straightforward. But the job becomes significantly harder when the image lacks specific location cues or is taken indoors or shows a pet or food or some other detail. Nevertheless, humans are surprisingly good at this task. To help, they bring to bear all kinds of knowledge about the world such as the type and language of signs on display, the types of vegetation, architectural styles, the direction of traffic, and so on. Humans spend a lifetime picking up these kinds of geolocation cues. So it’s easy to think that machines would struggle with this task. And indeed, they have. Today, that changes thanks to the work of Tobias Weyand, a computer vision specialist at Google, and a couple of pals. These guys have trained a deep-learning machine to work out the location of almost any photo using only the pixels it contains. Read more of this story at Slashdot.
