+ - World's Most Powerful Laser Diode Arrays Deployed->

Submitted by Zothecula
Zothecula (1870348) writes "The High-Repetition-Rate Advanced Petawatt Laser System (HAPLS) under construction in the Czech Republic is designed to generate a peak power of more than 1 quadrillion watts (1 petawatt, 1015 watts). The key component to this instrument – the laser "pump" – will be a set of solid-state laser diode arrays recently constructed by Lawrence Livermore National Laboratory (LLNL). At peak power, this electronic assemblage develops a staggering 3.2 million watts of power and are the most powerful laser diode arrays ever built."

+ - Issue tracker for non-engineers?

Submitted by purplie
purplie (610402) writes "My non-technical spouse is an analyst in a small county government department, a handful of people plus some contractors for projects. Their project/task management is mouth-to-mouth, sticky notes, and emails, and it's driving them crazy.

I want to suggest something like an issue tracker. It would have to work for tasks both large (year-long investigations) and small (arranging catering for a meeting).

The issue trackers I'm familiar with with are too software-development-oriented, or make too many assumptions about your "agile" religion. Are there any good options for non-engineers?

They use mainly Windows and have iPads. I don't like web-based tools, but that might work better for them because they don't have administrative privs on their machines. Something that also incorporates a wiki might be nice. There will be resistance if it's not really easy to use."

+ - Britain's oldest human brain preserved for 2500 years by mud->

Submitted by hypnosec
hypnosec (2231454) writes "Oldest human brain in the UK is believed to have been preserved for over 2,500 years by mud, archaeologists have revealed. The brain was found inside a decapitated skull, with the jaw and two vertebrae still attached, at an Iron Age dig site near York, UK, in 2008. Based on radiocarbon dating of a sample of the jaw bone, researchers have determined that the person lived in the 6th century BC and is likely to be a man between 26 and 45 years old. A team of 34 experts have been working to study and conserve the brain since its discovery. An examination of the vertebrae in the neck shows that he was first hit hard on the neck, and then the neck was severed with a small sharp knife. York Archaeological Trust said the skull had been buried in wet, clay-rich ground providing an oxygen-free burial."

+ - Linux and multiple internet uplinks: a new tool

Submitted by Alessandro Zarrilli
Alessandro Zarrilli (4027561) writes "Linux is able do multipath routing since a long time: it means being able to have routes with multiple gateways and to use them in a (weighted) round-robin fashion. But Linux misses a tool to actively monitor the state of internet uplinks and change the routing accordingly. Without it, on a LAN perspective, it's like having a RAID0 on network: just one uplink goes down and all of your LAN-to-WAN traffic goes down too. Documentation and examples on the subject are lacking, existing solutions are few and deeply integrated in firewall/routing specific distributions. To address these issues, a new stand alone tool was just released: Fault Tolerant Router. It also includes a complete (iptables + ip policy routing) configuration generator."

+ - Global SIM card cyber 'heist' organised by US and UK spy agencies->

Submitted by Anonymous Coward
An anonymous reader writes "Intelligence agencies in the United States and the UK hacked into the SIM card database of a major manufacturer in order to steal encryption codes which allowed them to decode data from mobile phones, according to a US report. The Intercept claimed that the breach was revealed in a number of files provided by former US intelligence contractor and whistleblower Edward Snowden. The company targeted in the hacking is thought to be Gemalto, producer of around two million SIM cards for SPs such as AT&T, T-Mobile and Verizon, across 85 countries. The stolen codes allowed American and British spies to eavesdrop easily on calls, texts, and emails passing across mobile phone networks. The Intercept called the hack a “great SIM heist”, and the manufacturing firm has confirmed that it is taking the allegations “very seriously.”"

+ - LHC Season 2: A stronger machine->

Submitted by MaiqueSCP
MaiqueSCP (3575793) writes "In early 2013, after three years of running, the Large Hadron Collider (LHC) shut down for planned maintenance. Hundreds of engineers and technicians spent two years repairing and strengthening the accelerator in preparation for running at higher energy. Now the world’s largest and most powerful particle collider is ready to start up again. So what’s new?"

+ - Reverse Engineering the Nike+ FuelBand's Communications Protocol->

Submitted by Anonymous Coward
An anonymous reader writes "Security researcher Simone Margaritelli has reverse engineered the Bluetooth low-energy communications protocol for his Nike+ FuelBand SE, a wrist-worn activity tracker. He learned some disturbing fact: "The authentication system is vulnerable, anyone could connect to your device. The protocol supports direct reading and writing of the device memory, up to 65K of contents. The protocol supports commands that are not supposed to be implemented in a production release (bootloader mode, device self test, etc)." His post explains in detail how he managed this, and how Nike put effort into creating an authentication system, but then completely undermined it by using a hard-coded token. Margaritelli even provides a command list for the device, which can do things like grab an event log, upload a bitmap for the screen, and even reset the device."

+ - What kind of stars actually gave rise to us?

Submitted by StartsWithABang
StartsWithABang (3485481) writes "You've heard the famous quote before, that "we are star stuff." This is true, of course, since only hydrogen and helium existed shortly after the Big Bang, so the elements must have been made in stars. But many of the ones we think of as necessary for life — including phosphorous, sodium, chlorine, magnesium, calcium, potassium, copper, and zinc — didn't come from a single generation of previous, massive stars. It took a slow-burning star like our own Sun to make dozens of elements that are abundant on Earth today."

+ - adds close to 2400 DOS games

Submitted by Bugamn
Bugamn (1769722) writes " added a new library of DOS games. The games are playable on the browser through EM-DOSBOX, a port of the DOS emulator. The games are provided without instructions, so some experimentation (or search for old manuals) might be necessary. The library does not mention any copyright concerns, although some of the games can be found for sale on sites such as Steam and GoG."

+ - Scientists discover "recipe" for making planet just like Earth->

Submitted by sciencehabit
sciencehabit (1205606) writes "Only a small number of worlds look anything like Earth: roughly the same size and at the right distance from their star for liquid water to be present. But are these Earth-like exoplanets really made from the same sort of stuff—a rocky surface, an iron core, and just a dash of water? A new study suggests that exoplanets, at least up to 1.6 times the mass of Earth, follow pretty much the same recipe as our home. Indeed, scientists have come up with the core ingredients to make such a world. So if we’re looking for life out there, we can probably ignore anything bigger than that."

+ - Disabled Dog is Now Able to Run, Thanks to 3D-Printed Prostheses->

Submitted by Zothecula
Zothecula (1870348) writes "Derby the dog faced a challenge right from Day One. Due to a congenital deformity, he was born with very small forelegs and no front paws. This resulted in his ending up in the care of Hillsborough, New Hampshire-based dog rescue group, Peace and Paws. Fortunately, he then proceeded into the foster home of Tara Anderson. She works for 3D printing company 3D Systems (3DS), and set about using her employer's technology to make him a set of prostheses. As a result, he's now able to run for the first time."

+ - Ron Wyden introduces bill to ban FBI 'backdoors' in tech products->

Submitted by Anonymous Coward
An anonymous reader writes "Senator Ron Wyden (D-OR) is trying to proactively block FBI head James Comey's request for new rules that make tapping into devices easier. The Secure Data Act would ban agencies from making manufacturers alter their products to allow easier surveillance or search, something Comey has said is necessary as encryption becomes more common and more sophisticated. "Strong encryption and sound computer security is the best way to keep Americans' data safe from hackers and foreign threats," said Wyden in a statement. "It is the best way to protect our constitutional rights at a time when a person's whole life can often be found on his or her smartphone.""

+ - Electric eel shocks like a Taser->

Submitted by Science_afficionado
Science_afficionado (932920) writes "After a nine month study, a Vanderbilt biologist has determined that the electric eel emits series of millisecond, high-voltage pulses to paralyze its prey just before it attacks. The high-voltage pulses cause the motor neurons in its target to violently contract, leaving it temporarily immobilized in the same fashion as the high-voltage pulses produced by a Taser. He documented this effect using high-speed video. The eel, which is nocturnal and has very poor eyesight, also uses closely spaced pairs of high-voltage pulses when hunting for hidden prey. He determined that the pulses cause the prey's body to twitch which produces water movements that the eel uses to locate its position even when it's hidden from view."

+ - SpaceShipTwo's Rocket Engine Did Not Cause Fatal Crash->

Submitted by astroengine
astroengine (1577233) writes "It wasn’t SpaceShipTwo’s hybrid rocket motor — which was flying on Friday with a new type of fuel — that caused the fatal crash, the head of the accident investigation agency said late Sunday. The ship’s fuel tanks and its engine were recovered intact, indicating there was no explosion. “They showed no signs of burn-through, no signs of being breached,” Christopher Hart, acting chairman of the National Transportation and Safety Board, told reporters at the Mojave Air and Space Port in Mojave, Calif. Instead, data and video relayed from the ship show its hallmark safety feature — a foldable tail section designed for easy re-entry into the atmosphere from space — was deployed early, causing the in-flight break-up."

+ - Physicists identify possible new particle behind dark matter->

Submitted by sciencehabit
sciencehabit (1205606) writes "Like cops tracking the wrong person, physicists seeking to identify dark matter—the mysterious stuff whose gravity appears to bind the galaxies—may have been stalking the wrong particle. In fact, a particle with some properties opposite to those of physicists' current favorite dark matter candidate—the weakly interacting massive particle, or WIMP—would do just as good a job at explaining the stuff, a quartet of theorists says. Hypothetical strongly interacting massive particles—or SIMPs—would also better account for some astrophysical observations, they argue."
