+ - 204 Vaccine Could Protect Soldiers from Post-Traumatic Stress Disorders

Submitted by Hugh Pickens DOT Com
Hugh Pickens DOT Com (2995471) writes "PTSD affects about 7.7 million American adults, including soldiers and victims of crimes, accidents, or natural disasters. About 40 to 50 percent of patients recover within five years but the rest never get better. Now Discovery Magazine reports that medical researchers say they have discovered a possible “vaccine” for post-traumatic stress disorder that could protect soldiers serving in war by regulating ghrelin, a hormone produced during stressful situations, that primes the brain for PTSD. “You would get a shot, and for a year it would lower your ghrelin levels,” says Ki Gossens, assistant professor of brain and cognitive sciences at MIT, and lead author of the paper in the journal Molecular Psychiatry. “When you were deployed and exposed to the stress of combat, your ghrelin levels would go up and the vaccine would combat that. That should reduce the incidence of PTSD." Gossens says that ghrelin operates alongside the brain’s other “fight or flight” neurochemical system, which is controlled by the hormones cortisol and adrenaline. That signaling route is known as the hypothalamus-pituatary-adrenal pathway, or HPA. “What we are suggesting is that the ghrelin pathway operates in parallel,” Gossens said. “We think the emotional disorders (such as PTSD) following trauma exposure are the result of elevated ghrelin rather than HPA." Gossens believes that since many ghrelin-related anti-obesity drugs have already passed federal human safety trials, it would give them a leg up on developing some kind of vaccine for PTSD."

+ - 185 NSA Director Keith Alexander Is Reportedly Stepping Down->

Submitted by Daniel_Stuckey
Daniel_Stuckey (2647775) writes "Keith Alexander will step down by April or May of next year. What's more, the agency’s deputy director Chris Inglis also plans to retire by the end of next year, anonymous US officials told Reuters today.

Though the news comes in the midst of a global public backlash over the NSA's widespread surveillance programs, it's worth pointing out that Alexander had revealed his plans to retire before Edward Snowden leaked details of PRISM in June. Officials didn’t give a reason for his departure."

Submitted by colinneagle
colinneagle (2544914) writes "The timing for this study is interesting, given the arrests of two teenagers believed to have bullied a 12-year-old classmate until she committed suicide, but Microsoft found that 94% of parents said they allow their kids unsupervised access to at least one device or online service like email or social networks. The average age at which most children are allowed access to at least one online service, such as email or social media, was 8 years old, while 40% allow children under the age of 7 to access a computer unsupervised."

Submitted by rjmarvin
rjmarvin (3001897) writes "$7 million in federal grant money originally tasked with terrorism prevention is now being used to fund construction of a new data center http://sdt.bz/64221 in Oakland to electronically gather and analyze data around the clock from a variety of sensors and databases, displaying selected info on a bank of giant monitors. The center will mine massive data streams, helping the police department tap into 911 calls, port and traffic cameras, license plate readers, gunshot sensors, social media posts and commuters’ electronic toll payments. It takes the buzzwords "Big Data" and "surveillance state" to a whole new level."

Submitted by DeviceGuru
DeviceGuru (1136715) writes "Suitable Technologies is offering $50 rentals of its Beam mobile telepresence robot, allowing 50 robotics enthusiasts to remotely attend the RoboBusiness conference in Santa Clara, Calif. on Oct. 23-25. The Ubuntu- and ROS-based Beam will be available to the first 50 applicants, letting them explore the show at up to 1.5 meters/sec and interact with others via video conferencing. The bots will be allowed everywhere on the show floor as well as in conference rooms, and the show will be open late to accommodate remote users from distant time zones. The Beam is a good choice for remotely exploring conferences, saving users the cost and time of traveling to an event, says Suitable Tech; for example, RoboBusiness registration costs $1,595, not including hotel and travel. A list of the conference's keynotes, which include one by Christ Urmson, director of Google's Self-Driving Cars project, is available here."

skaterperson (875923) writes "Nearly three hundred people gathered around 9PM, stopping traffic and packing a street corner to watch a crowdfunded video on the NSA spying programs, projected high on the side of a building from a bike-mounted projector & sound system. Now the video's live and we can all watch it. One impression was just impossible to avoid: tons of people care about this issue, perhaps more than any issue in the Internet freedom space. The mission is to reach reach them all and build a movement, and no doubt they can take apart the NSA’s mass spying operation piece by piece."

A key new measurement of Mars’ atmosphere by NASA’s Curiosity rover provides the most definitive evidence yet of the origins of Mars meteorites while at the same time providing a way to rule out Martian origins of other meteorites."

Submitted by dryriver
dryriver (1010635) writes "The Guardian reports: British Prime Minister David Cameron has encouraged a Commons select committee to investigate whether the Guardian has broken the law or damaged national security by publishing secrets leaked by the National Security Agency whistleblower Edward Snowden. He made his proposal in response to a question from former defence secretary Liam Fox, saying the Guardian had been guilty of double standards for exposing the scandal of phone hacking by newspapers and yet had gone on to publish secrets from the NSA taken by Snowden. Speaking at prime minister's questions on Wednesday, Cameron said: 'The plain fact is that what has happened has damaged national security and in many ways the Guardian themselves admitted that when they agreed, when asked politely by my national security adviser and cabinet secretary to destroy the files they had, they went ahead and destroyed those files. 'So they know that what they're dealing with is dangerous for national security. I think it's up to select committees in this house if they want to examine this issue and make further recommendations.' There are as many as four committees that might take up David Cameron's suggestion, including the culture select committee, the home affairs select committee, the defence select committee and the intelligence and security select committee."

+ - 194 Report: Indonesia Now Top IP Source for Security Attacks

Submitted by curtwoodward
curtwoodward (2147628) writes "China has long been the top source of IP addresses used in security attacks, as monitored by Internet traffic firm Akamai's "State of the Internet" report. But earlier this year, malicious hackers found a new favorite country: Indonesia. Attacks originating from Indonesian IP addresses topped the list in the second quarter, representing 38 percent of all global attacks seen by Akamai, which handles about a third of Web traffic. Akamai also says that reports of DDoS attacks on its customers are growing very quickly, with a more than 50 percent rise in one quarter. The question now is whether that jump in DDoS activity is tied to periodic global unrest, or is the beginning of a new trend."

+ - 242 Uneven Enforcement Suspected at Nuclear Plants->

Submitted by mdsolar
mdsolar (1045926) writes "The number of safety violations at U.S. nuclear power plants varies dramatically from region to region, pointing to inconsistent enforcement in an industry now operating mostly beyond its original 40-year licenses, according to a congressional study awaiting release.

Nuclear Regulatory Commission figures cited in the Government Accountability Office report show that while the West has the fewest reactors, it had the most lower-level violations from 2000 to 2012 — more than 2½ times the Southeast's rate per reactor.

The Southeast, with the most reactors of the NRC's four regions, had the fewest such violations, according to the report, a copy of which was obtained by The Associated Press.

The striking variations do not appear to reflect real differences in reactor performance. Instead, the report says, the differences suggest that regulators interpret rules and guidelines differently among regions, perhaps because lower-level violations get limited review."
