Submission + - Scientists Halt Aging by Tweaking Activity in Almond-Sized Brain Region (counselheal.com)

An anonymous reader writes: Scientists have discovered for the first time that the body's aging switch may be located in the brain region that controls growth, reproduction and metabolism.
The latest study, published online in the journal Nature, revealed that the brain's hypothalamus, an almond-sized brain region located just above the brain stem deep in the brain, may be the body's "fountain of aging".
Experts believe the latest discovery could lead to new treatments for extending lifespan and combating age-related diseases

Submission + - Stoned Behind the Wheel: Driving Under the Influence of Pot Dr. Mohammad Speaks (marketwire.com) 1

maliburobert writes: Dr. Mohammad said, "In light of the recent changes in Marijuana-related law we are seeing across the United States, we seem to be moving in the wrong direction on several levels. Regardless of whether or not Marijuana is legal to purchase and consume, it is still a heavily addictive substance that poses significant threats to those who use it." Mohammad added, "While there are a multitude of health risks for Marijuana users, new research is surfacing that should terrify everyone, especially drivers. Marijuana use nearly doubles the chance of vehicular crashes, which is a horrific statistic considering the fact that global Marijuana use is dramatically rising. Lest we not forget the painful lessons we've learned from alcohol abuse and the massive toll it takes on innocent lives; just because Marijuana is becoming more acceptable, does not mean it is safe to operate vehicles under the influence."

Submission + - Energy Production Is As "Dirty" As Ever (singularityhub.com)

kkleiner writes: A recent report from International Energy Agency delivers some dire news: despite 20 years of efforts toward clean energy and a decade of growth in renewable energy, energy production remains as "dirty" as ever due to worldwide reliance on fossil fuels. With the global demand for energy expected to rise by 25 percent in the next 10 years, a renewed effort toward cleaner energy is desperately needed to avoid detrimental effects to the environment and public health.

Submission + - High school student faces Federal charges for scientific curiosity

SemperCogito writes: This petition at Whitehouase.gov (http://wh.gov/zx1m) explains:

Kiera Wilmot is a Florida high school student with a perfect behavior record and good grades. She was recently arrested, hauled from school in handcuffs, expelled, and now faces Federal charges — all because of shameful over-reaction by school officials and law enforcement.

Out of curiosity and the scientific spirit, she mixed some common household chemicals together, creating a vigorous reaction that blew the top off the container she used. No one was hurt — no damage was done. But instead of appluading her boldness of spirit and connecting her to a science teacher that could mentor it, she is being treated like a criminal!

This travesty of justice and education must be stopped. Reinstate her, and wipe her records clean. Then celebrate her!

Submission + - Perpetual Motion Test Could Amend Theory of Time

tocs writes: Nobel Prize-winning physicist Frank Wilczek wants to a build a perpetual motion machine . The concept uses Time Crystals, the idea that crystals can be extended into the fourth dimension, built of calcium ions to demonstrate the concept. If successful it might not lead to boundless energy but we could end up with machines that outlive the universe.

Submission + - Lessons Learned When Porting Source Engine to Linux 1

jones_supa writes: Here is a gem for all the programmers. Representatives from the team at Valve take a look at the difficulties they went through in porting the Source game engine to Linux. In the presentation, they mostly discuss about the methodologies of switching from DirectX to OpenGL while comparing the APIs and talking about the various tools they used to do the port. The developers found that OpenGL actually incurs less overhead than DirectX, and they note that with OpenGL you can bring the latest draft on any OS, including the still large base of Windows XP computers. A PDF compilation of the slides is also available.

Submission + - Ask Slashdot: Best OSS embedded development platform

AchilleTalon writes: As many of you may know, there is two main competitors on the Windows platform for embedded software developement, namely IAR and Keil. By embedded development, I mean development for microprocessors like the wellknown 8051 and the likes. I do not intent to mean mobile platforms which include a complete OS in first place.

I am seeking for alternatives to IAR and Keil in the OSS world. Even if I can find pieces of code here and there, I haven't found yet a fully integrated development platform. Does it exist? What do you use, you the serious embedded developers out there?

Submission + - Refuses to Decrypt -- Claims Fifth Amendment (jsonline.com)

jsrjsr writes: A West Allis, WI computer scientist is refusing to decrypt hard drives that the FBI claims contain child pornography. He has consistently refused to admit anything in the case, which a judge says has the effect of strengthening his claim of fifth amendment protection against incriminating himself.

Submission + - Researchers Link Roundup® Herbicide to Cancer, Autism, Parkinsonism 2

Freshly Exhumed writes: The journal Entropy has published a peer-reviewed paper by authors Anthony Samsel, an independent scientist and consultant, and Stephanie Seneff, a senior research scientist at MIT, that contradicts Monsanto's claims that its widely-used herbicide glyphosate (a.k.a. Roundup®) is safe and non-toxic. From the paper: 'Glyphosate, the active ingredient, is the most popular herbicide used worldwide. The industry asserts it is minimally toxic to humans, but here we argue otherwise. Residues are found in the main foods of the Western diet, comprised primarily of sugar, corn, soy and wheat. Glyphosate's inhibition of cytochrome P450 (CYP) enzymes is an overlooked component of its toxicity to mammals. CYP enzymes play crucial roles in biology, one of which is to detoxify xenobiotics. Thus, glyphosate enhances the damaging effects of other food borne chemical residues and environmental toxins.' tl:dr Dude it wrecks ya gut so whacked shizzle happens down there real easier.

Submission + - Solving the Mystery of Supercharged Lightning (sciencemag.org)

sciencehabit writes: The serendipitous flybys of two satellites near a tropical thunderstorm have given researchers an unprecedented look at terrestrial gamma-ray flashes—a mysterious, high-energy phenomenon that scientists first observed in 1991. First thought to be generated at high altitudes, researchers have recently pinned down the origin of the fleeting lightning-linked bursts—one of the most energetic surges of natural electromagnetic radiation on Earth—to altitudes below 20 kilometers, in the layer of the atmosphere where most weather happens. Now, analyses of data gathered in 2006 by two satellites—one carrying a down-gazing camera and the other a gamma ray detector—as well as a ground-based lightning detector in North Carolina, reveal that these flashes start out, as does most lightning, as a small channel of charged particles within the storm cloud. Besides shedding new light on how terrestrial gamma-ray bursts unfold, the new analysis suggests that the phenomena are about twice as common as previously suspected, the researchers say.

Comment Re:Barrel and slide/bolt too? (Score 1) 625

BTW, I don't know anyone who owns an AR16. In fact, I'd wager that no one anywhere owns an AR16.

The AR-16 was Eugene Stoner's last design for ArmaLite. It's possible that a prototype still exists somewhere. It was a selective-fire, gas-operated rifle in 7.62 NATO (similar to .308 Winchester).
