sciencehabit writes: NASA hopes to send the first round-trip, manned spaceflight to Mars by the 2030s. If the mission succeeds, astronauts could spend several years potentially being bombarded with cosmic rays—high-energy particles launched across space by supernovae and other galactic explosions. Now, a study in mice suggests these particles could alter the shape of neurons, impairing astronauts' memories and other cognitive abilities. In the prefrontal cortex, a brain region associated with executive function, a range of high-level cognitive tasks such as reasoning, short-term memory, and problem-solving, neurons had 30% to 40% fewer branches, called dendrites, which receive electrical input from other cells.

ferrisoxide.com writes: A paper co-authored by researcher fellow Dr. Fiona Ingleby and evolutionary biologist Dr. Megan Head — on how gender differences affect the experiences that PhD students have when moving into post-doctoral work — was rejected by peer-reviewed PLoS Onebecause they didn't ask a man for help.

A (male) peer reviewer for the journal suggested that the scientists find male co-authors, to prevent "ideologically biased assumptions." The same reviewer also provided his own ironically biased advice, when explaining that women may have fewer articles published because men's papers "are indeed of a better quality, on average," "just as, on average, male doctoral students can probably run a mile race a bit faster." PLoS One has apologized, saying, "We have formally removed the review from the record, and have sent the manuscript out to a new editor for re-review. We have also asked the Academic Editor who handled the manuscript to step down from the Editorial Board and we have removed the referee from our reviewer database."

Introduced in 2013, the cockpit iPads are used as an "electronic flight bag," replacing 16kg (35lb) of paper manuals which pilots are typically required to carry on flights. In some cases, the flights had to return to the gate to access Wi-Fi to fix the issue.

An anonymous reader writes: The Canadian government's unexpected budget decision to extend the term of copyright for sound recordings came as a surprise to most copyright watchers, but not the music industry lobby, which was ready with a press release within minutes. How did the industry seemingly know this was coming? Michael Geist reports that records show the extension is the result of backroom lobbying with monthly meetings between senior government officials and music industry lobbyists paving the way for copyright term extension without public consultation or debate.

An anonymous reader writes: With news that Canada intends to extend the term of copyright for sound recordings and performers, the recording industry is now pushing the change by arguing that works entering the public domain is not in the public interest. It is hard to see how anyone can credibly claim that works are "lost" to the public domain and that the public interest in not served by increased public access, but if anyone would make the claim, it would be the recording industry.

Mark Wilson writes: Bounty programs benefit everyone. Companies like Microsoft get help from security experts, customers gain improved security, and those who discover and report vulnerabilities reap the rewards financially. Or at least that's how things are supposed to work. Having reported a series of security problems to discount and deal site Groupon, security researcher Brute Logic from XSSposed.org was expecting a pay-out — but the site refuses to give up the cash. In all, Brute Logic reported more than 30 security issues with Groupon's site, but the company cites its Responsible Disclosure policy as the reason for not handing over the cash.

The Washington Post reports that the "supervolcano" beneath Yellowstone National Park (which, thankfully, did not kill us all in 2004, or in 2008 ) may be more dangerous when it does erupt than anyone realized until recently. Scientists have today published a paper documenting their discovery of an even larger, deeper pool of magma below the already huge reservoir near the surface. From the article: On Thursday, a team from the University of Utah published a study, in the journal Science, that for the first time offers a complete diagram of the plumbing of the Yellowstone volcanic system. The new report fills in a missing link of the system. It describes a large reservoir of hot rock, mostly solid but with some melted rock in the mix, that lies beneath a shallow, already-documented magma chamber. The newly discovered reservoir is 4.5 times larger than the chamber above it. There's enough magma there to fill the Grand Canyon. The reservoir is on top of a long plume of magma that emerges from deep within the Earth's mantle. ... “This is like a giant conduit. It starts down at 1,000 kilometers. It's a pipe that starts down in the Earth," said Robert Smith, emeritus professor of geophysics at the University of Utah and a co-author of the new paper. ... The next major, calderic eruption could be within the boundaries of the park, northeast of the old caldera. “If you have this crustal magma system that is beneath the pre-Cambrian rocks, eventually if you get enough fluid in that system, enough magma, you can create another caldera, another set of giant explosions," Smith said. "There’s no reason to think it couldn’t continue that same process and repeat that process to the northeast.”

HughPickens.com writes: The NYT reports that President Obama has offered an emotional apology for the accidental killing of two hostages held by Al Qaeda, one of them American, in a United States government counterterrorism operation in January, saying he takes "full responsibility" for their deaths. "As president and as commander in chief, I take full responsibility for all our counterterrorism operations," including the one that inadvertently took the lives of the two captives, a grim-faced Obama said in a statement to reporters in the White House briefing room. The White House earlier released an extraordinary statement revealing that intelligence officials had confirmed that Warren Weinstein, an American held by Al Qaeda since 2011, and Giovanni Lo Porto, an Italian held since 2012, died during the operation. Gunmen abducted Warren Weinstein in 2011 from his home in Lahore, Pakistan. They posed as neighbors, offered food and then pistol-whipped the American aid worker and tied up his guards, according to his daughter Alisa Weinstein.

The White House did not explain why it has taken three months to disclose the episode. Obama said that the operation was conducted after hundreds of hours of surveillance had convinced American officials that they were targeting an Al Qaeda compound where no civilians were present, and that "capturing these terrorists was not possible." The White House said the operation that killed the two hostages "was lawful and conducted consistent with our counterterrorism policies" but nonetheless the government is conducting a "thorough independent review" to determine what happened and how such casualties could be avoided in the future.

sciencehabit writes: In a decision that effectively recognizes chimpanzees as legal persons for the first time, a New York judge [Monday] granted a pair of Stony Brook University lab animals the right to have their day in court. The ruling marks the first time in U.S. history that an animal has been covered by a writ of habeus corpus, which typically allows human prisoners to challenge their detention. The judicial action could force the university, which is believed to be holding the chimps, to release the primates, and could sway additional judges to do the same with other research animals. Update: 04/21 21:39 GMT by S : Science has updated their article with news that the court has released an amended order (PDF) with the words "writ of habeas corpus" removed, no longer implying that chimps have legal personhood. The order still allows the litigation to go forward, but we'll have to wait for resolution.

Patrick O'Neill writes: After years of relative neglect, Tor has been able to dedicate increasing time and resources to its hidden services thanks to funding in part by DARPA, as well as an upcoming crowdfunding campaign. DARPA's funding lasts 1-3 years and covers several projects including security and usability upgrades that close the gap between hidden services and the everyday Internet. "Next-generation hidden services may be run from multiple hosts to better deal with denial of service attacks and high traffic in general, a potentially big power boost that further closes the gap between the Dark Net and normal websites. ... Hidden services, which make up about 4 percent of the entire Tor network, have until recently been relatively neglected when it comes to funding and developing."

Mark Wilson writes Twitter has updated its privacy policy, creating a two-lane service that treats U.S. and non-U.S. users differently. If you live in the U.S., your account is controlled by San Francisco-based Twitter Inc, but if you're elsewhere in the world (anywhere else) it's handled by Twitter International Company in Dublin, Ireland. The changes also affect Periscope. What's the significance of this? Twitter Inc is governed by U.S. law; it is obliged to comply with NSA-driven court requests for data. Data stored in Ireland is not subject to the same obligation. Twitter is not alone in using Dublin as a base for non-U.S. operations; Facebook is another company that has adopted the same tactic. The move could also have implications for how advertising is handled in the future.

mpicpp writes The Florida mail carrier accused of landing a gyrocopter outside the U.S. Capitol on Wednesday was charged in federal court Thursday and has been barred from returning to the District of Columbia or flying any aircraft, officials said. Douglas Hughes, 61, was charged with violating aircraft registration requirements, a felony, and violating national defense airspace, a misdemeanor. If convicted, he could be sentenced to up to three years in prison for the felony and one year in prison for the airspace violation. U.S. Magistrate Judge Deborah A. Robinson also barred Hughes from the District of Columbia, except for court appearances, and said he must stay away from the Capitol, White House and nearby areas while he is there. He will also have to hand over his passport.

HughPickens.com writes: Aaron Kinney reports in the San Jose Mercury News that scientists have captured the first clear images of the USS Independence, a radioactivity-polluted World War II aircraft carrier that rests on the ocean floor 30 miles off the coast of Half Moon Bay. The Independence saw combat at Wake Island and other decisive battles against Japan in 1944 and 1945 and was later blasted with radiation in two South Pacific nuclear tests. Assigned as a target vessel for the Operation Crossroads atomic bomb tests, she was placed within one-half-mile of ground zero and was engulfed in a fireball and heavily damaged during the 1946 nuclear weapons tests at Bikini Atoll. The veteran ship did not sink, however (though her funnels and island were crumpled by the blast), and after taking part in another explosion on 25 July, the highly radioactive hull was later taken to Pearl Harbor and San Francisco for further tests and was finally scuttled off the coast of San Francisco, California, on 29 January 1951. "This ship is an evocative artifact of the dawn of the atomic age, when we began to learn the nature of the genie we'd uncorked from the bottle," says James Delgado. "It speaks to the 'Greatest Generation' — people's fathers, grandfathers, uncles and brothers who served on these ships, who flew off those decks and what they did to turn the tide in the Pacific war."

Delgado says he doesn't know how many drums of radioactive material are buried within the ship — perhaps a few hundred. But he is doubtful that they pose any health or environmental risk. The barrels were filled with concrete and sealed in the ship's engine and boiler rooms, which were protected by thick walls of steel. The carrier itself was clearly "hot" when it went down and and it was packed full of fresh fission products and other radiological waste at the time it sank. The Independence was scuttled in what is now the Gulf of the Farallones sanctuary, a haven for wildlife, from white sharks to elephant seals and whales. Despite its history as a dumping ground Richard Charter says the radioactive waste is a relic of a dark age before the enviornmental movement took hold. "It's just one of those things that humans rather stupidly did in the past that we can't retroactively fix.""

jyosim writes Studies have shown that as many as 90 percent of campus rapes are committed by repeat offenders. A new system is designed to help identify serial assaulters, by letting students anonymously report incidents in order to look for patterns. But some argue that having the ability to report someone with just the click of a button may not be a good thing. Andrew T. Miltenberg, a New York lawyer who represents young men accused of sexual misconduct, says though the system seems well intended, he is concerned about dangers it may pose to students who are accused. 'We're all guilty of pressing send on an angry text or email that, had we had to put it into an actual letter and proofread, we probably wouldn't have sent,' he says.

Hallie Siegel writes: Should robots be allowed to make life and death decisions? This will be the topic of heated debate at the United Nations (UN) Palais des Nations in Geneva next week (April 13-17th, 2015). As part of the Convention on Certain Conventional Weapons (CCW), experts from all over the world will gather to discuss 'questions related to emerging technologies in the area of lethal autonomous weapons systems.' The Open Roboethics Research Initiative will be presenting public views at the debate. Human rights groups are urging the UN to ban such weapons. A new report titled "Mind the Gap" details the accountability issues that need to be solved before going any further. "A key concern with fully autonomous weapons is that they would be prone to cause civilian casualties in violation of international humanitarian law and international human rights law. The lack of meaningful human control that characterizes the weapons would make it difficult to hold anyone criminally liable for such unlawful actions."
