Tracking System Bug Delays SpaceX's DSCOVR Launch

Slashdot - Sun, 08/02/2015 - 11:47pm
The SpaceX two-fer launch that was scheduled for today has been scrubbed. NBC News reports that the launch was postponed until Monday at the earliest due to a problem with the range-tracking system in Florida. That means an ambitious second attempt to land the Falcon 9 rocket's first stage on an oceangoing platform will also have to be delayed. ... Satellites such as the Advanced Composition Explorer and Solar and Heliospheric Observatory, which are already located at the L1 point, can provide up to an hour's warning of major storms. Both those satellites are well past their anticipated lifetimes, however, and DSCOVR is designed to provide a much-needed backup. SpaceX's two-stage Falcon 9 rocket will boost DSCOVR into a preliminary orbit, but it will take 110 days of in-space maneuvers to get the probe into the right position. This launch would mark the first time that SpaceX has sent a spacecraft so far, and it will be judged a success if DSCOVR reaches its intended orbit. The delayed launch could take place as soon as tomorrow (Monday) evening.

Silk Road Drug Dealer Pleads Guilty After Federal Sting

Slashdot - Sun, 08/02/2015 - 10:55pm
Ars Technica reports that A 26-year-old Columbus, Ohio man has pleaded guilty to selling drugs through the Silk Road website. David Lawrence Handel apparently obtained methylone and other drugs from a supplier in China, which he then sold to buyers on the online black market. Among those buyers were Maryland federal agents, who were making undercover purchases. Handel shipped the drugs to them through the US Postal Service, according to the United States Attorney’s Office for the District of Maryland. ... Handel faces up to 20 years in prison for drug trafficking and up to life for using and possessing a firearm. His sentencing is scheduled for May 15.

Free-As-In-Beer Electricity In Greece?

Slashdot - Sun, 08/02/2015 - 9:58pm
PolygamousRanchKid writes New Greek Prime Minister Alexis Tsipras will lay out his radical left-wing government's policies in a speech later on Sunday, firmly rejecting any more austerity forced on his debt-strapped country by its euro zone partners. In his first major speech to parliament as premier, Tsipras is expected to say that Greece wants no more bailout money, plans to renegotiate its debt deal and wants a "bridge agreement" to tide the country over until a new pact is sealed. A second part of the speech will touch on his government's social and fiscal policy over the longer term and is likely to repeat pledges for such things as a rise in the minimum wage and free electricity for poorer Greeks. Which gets me to thinking: with free electricity, wouldn't that be a great business opportunity, to build a cloud of servers in poorer Greeks' basements? Maybe that is the real plan behind the free electricity idea.

RMS Objects To Support For LLVM's Debugger In GNU Emacs's Gud.el

Slashdot - Sun, 08/02/2015 - 8:57pm
An anonymous reader writes with the news that Richard Stallman is upset over the prospect of GNU Emacs's Grand Unified Debugger (Gud.el) supporting LLVM's LLDB debugger. Stallman says it looks like there is a systematic effort to attack GNU packages and calls for the GNU Project to respond strategically. He wrote his concerns to the mailing list after a patch emerged that would optionally support LLDB alongside GDB as an alternative debugger for Emacs. Other Emacs developers discounted RMS' claims by saying Emacs supports Windows and OS X, so why not support a BSD-licensed compiler/debugger? The Emacs maintainer has called the statements irrelevant and won't affect their decision to merge the LLDB support.

'Virtual virus' unfolds the flu on a CPU

Science Daily - Sun, 08/02/2015 - 8:27pm
Combining experimental data from X-ray crystallography, NMR spectroscopy, cryoelectron microscopy and lipidomics, researchers have built a complete model of the outer envelope of an influenza A virion for the first time. The approach, known as a coarse-grained molecular dynamics simulation, has allowed them to generate trajectories at different temperatures and lipid compositions -- revealing various characteristics that may help scientists better understand how the virus survives in the wild or find new ways to combat it.

Promising peptide for TBI, heart attack and stroke

Drug detectives

Science Daily - Sun, 08/02/2015 - 8:27pm
Good drugs are hard to design: they must not only effectively treat a medical condition, but they must also do so without having side effects that outweigh their benefits. Sometimes, toxic side effects aren't discovered until late in development, when substantial time and money have already been invested. Now, researchers have devised a new drug screen that capitalizes on the tendency of toxic compounds to alter the properties of the lipid bilayer that encases cells.
