Hacking Your Body Through a Nerve In Your Neck 30

agent elevator writes: IEEE Spectrum has a feature (part of its Hacking the Human OS issue) on the future of vagus nerve stimulation, a device-based therapy with the potential to treat a ridiculously wide variety of ailments: epilepsy, depression, stroke, tinnitus, heart failure, migraines, asthma, the list goes on. One problem is that, because it required an implant (a bit like a pacemaker), it was never anybody's first-choice therapy. But now there's a non-invasive version, a device you just hold to your neck twice a day for a few minutes. It's being trialed first for migraines and cluster headaches (which sound horrible). If it works, vagus nerve stimulation could compete directly with drug treatments on cost and convenience and it would let doctors find new ways to hack human physiology.

ClockEndGooner writes: A study conducted by the Netherlands Organization for Applied Scientific Research found that low frequency and long wavelength jet engine droning noise was significantly reduced in the fall after farmers plowed their fields near Amsterdam's Schiphol Airport. The remaining furrows "had multiple ridges to absorb the sound waves, deflected the sound and muted the noise." This led to the development of the Buitenschot Land Art Park, a buffer park featuring "land art" that has significantly reduced aircraft noise without requiring cuts in the number of allowed flights in and out of the airport. The land art park has also provided neighbors with additional recreational paths and sports fields in the same space.

Florida Hospital Shows Normal Internet Lag Time Won't Affect Remote Robotic Surgeries 104

Lucas123 writes: Remote robotic surgery performed hundreds or even thousands of miles away from the physician at the controls is possible and safe, according to the Florida Hospital that recently tested Internet lag times for the technology. Roger Smith, CTO at the Florida Hospital Nicholson Center in Celebration, Fla., said the hospital tested the lag time to a partner facility in Ft. Worth, Texas and found it ranged from 30 to 150 milliseconds, which surgeons could not detect as they moved remote robotic laparoscopic instruments. The tests, performed using a surgical simulator called a Mimic, will now be performed as if operating remotely in Denver and then Loma Linda, Calif. The Mimic Simulator system enables virtual procedures performed by a da Vinci robotic surgical system, the most common equipment in use today; it's used for hundreds of thousands of surgeries every year around the world. With a da Vinci system, surgeons today can perform operations yards away from a patient, even in separate but adjoining rooms to the OR. By stretching that distance to tens, hundreds or thousands of miles, the technology could enable patients to receive operations from top surgeons that would otherwise not be possible, including wounded soldiers near a battlefield. The Mimic Simulator was able to first artificially dial up lag times, starting with 200 milliseconds all the way up to 600 milliseconds.

Crowdfunded, Solar-powered Spacecraft Goes Silent 309

from the have-you-tried-turning-it-off-and-then-on-again dept.
Last week saw the successful launch of the Planetary Society's LightSail spacecraft, the solar-powered satellite that runs Linux and was crowdfunded on Kickstarter. The spacecraft worked flawlessly for two days, but then fell silent, and the engineering team has been working hard on a fix ever since. They've pinpointed the problem: a software glitch. "Every 15 seconds, LightSail transmits a telemetry beacon packet. The software controlling the main system board writes corresponding information to a file called beacon.csv. If you're not familiar with CSV files, you can think of them as simplified spreadsheets—in fact, most can be opened with Microsoft Excel. As more beacons are transmitted, the file grows in size. When it reaches 32 megabytes—roughly the size of ten compressed music files—it can crash the flight system." Unfortunately, the only way to clear that CSV file is to reboot LightSail. It can be done remotely, but as anyone who deals with crashing computers understands, remote commands don't always work. The command has been sent a few dozen times already, but LightSail remains silent. The best hope may now be that the system spontaneously reboots on its own.

Ask Slashdot: What Happens If We Perfect Age Reversing? 565

ourlovecanlastforeve writes: With biologists getting closer and closer to reversing the aging process in human cells, the reality of greatly extended life draws closer. This brings up a very important conundrum: You can't tell people not to reproduce and you can't kill people to preserve resources and space. Even at our current growth rate there's not enough for everyone. Not enough food, not enough space, not enough medical care. If — no, when — age reversal becomes a reality, who gets to live? And if everyone gets to live, how will we provide for them?

New submitter hamsterz1 writes: U.S. Officials say that the military mistakenly sent live anthrax to laboratories in nine states and an air base in South Korea, after apparently failing to properly inactivate the bacteria. Four lab workers in the United States and up to 22 overseas have been given precautionary medical treatment. The CDC is investigating the incident and Pentagon spokesman Colonel Steve Warren says, "Out of an abundance of caution, [the Defence Department] has stopped the shipment of this material from its labs pending completion of the investigation."

An anonymous reader writes: According to a Tuesday story in the UK edition of the International Business Times, Neil deGrasse Tyson, the celebrity astrophysicist and media personality, advocates a space race between the United States and China. The idea is that such a race would spur innovation and cause industry to grow. The Apollo race to the moon caused a similar explosive period of scientific research and engineering development.

Black Hole Plays Pool With Plasma 43

the monolith writes: The Hubble Space Telescope is revealing that there is a pool game in progress, with a long shot being played out on a cosmic scale. It appears that the first recorded shot was observed in 1992, while subsequent canon shots were recorded between 1994 an 2014. In actuality, the shots are plasma, the current player is a black hole, and the playing surface is galactic space itself. The BBC has a story on the observations and interpretations, while the journal Nature has the paywalled in-depth article. The current score is unknown, and one can only hope that there were no life forms involved in the collision.

How a Scientist Fooled Millions With Bizarre Chocolate Diet Claims 246

__roo writes: Did you know chocolate helps you lose weight? You can read all about this great news for chocoholics in the Daily Star, Daily Express, Irish Examiner, and TV shows in Texas and Australia, and even the front page of Bild, Europe's largest daily newspaper. The problem is that it's not true. A researcher who previously worked with Science to do a sting operation on fee-charging open access journals ran a real—but obviously flawed—study rigged to generate false positives, paid €600 to get it published in a fee-charging open access journal, set up a website for a fake institute, and issued press releases to feed the ever-hungry pool of nutrition journalists. The doctor who ran the trial had the idea to use chocolate, because it's a favorite of the "whole food" fanatics. "Bitter chocolate tastes bad, therefore it must be good for you. It's like a religion."

Ways To Travel Faster Than Light Without Violating Relativity 213

Posted by samzenpus
from the greased-lightning dept.
StartsWithABang writes: It's one of the cardinal laws of physics and the underlying principle of Einstein's relativity itself: the fact that there's a universal speed limit to the motion of anything through space and time, the speed of light, or c. Light itself will always move at this speed (as well as certain other phenomena, like the force of gravity), while anything with mass — like all known particles of matter and antimatter — will always move slower than that. But if you want something to travel faster-than-light, you aren't, as you might think, relegated to the realm of science fiction. There are real, physical phenomena that do exactly this, and yet are perfectly consistent with relativity.

BarbaraHudson writes: ABC is reporting that gene tests for risk of specific diseases are not as accurate as we'd like to think, with different labs giving different interpretations. Over 400 gene variants that could help one make medical decisions regarding breast and ovarian cancer or heart disease have different interpretations from different labs according to the study. "The magnitude of this problem is bigger than most people thought," said Michael Watson, executive director of the American College of Medical Genetics and Genomics, one of the study's authors. Researchers caution consumers to be careful when choosing where to have a gene test done and acting on the results.

Eloking writes: Professor Jun-Ichi Hayashi from the University of Tsukuba in Japan has discovered the regulation of two genes involved with the production of glycine are partly responsible for some of the characteristics of aging. With this finding he has been able to "flip the switches on a few genes back to their youthful position, effectively reversing the aging process." The Professor's findings cast doubt on the mitochondrial theory of aging, which proposes that the accumulation of mutations in the mitochondrial DNA are responsible for aging.

hypnosec writes: Scientists say the ozone layer is in good shape thanks to the Montreal Protocol, which has helped us avoid severe ozone depletion. Research suggests that the Antarctic ozone hole would have been 40% bigger by now if not for the international treaty. "Our research confirms the importance of the Montreal Protocol and shows that we have already had real benefits. We knew that it would save us from large ozone loss 'in the future', but in fact we are already past the point when things would have become noticeably worse," lead author Professor Martyn Chipperfield, from the School of Earth & Environment at the University of Leeds, said in a press release.

A Ph.D Thesis Defense Delayed By Injustice 77 Years 129

Posted by samzenpus
from the better-late-than-never dept.
Taco Cowboy writes: A story about a 102-year old lady doing her PhD thesis defense is not that common, but when the thesis defense was delayed by a whopping 77 years, that gotta raise some eyebrows. Ingeborg Syllm-Rapoport studied diphtheria at the University of Hamburg in Germany and in 1938, the 25-year old Protestant-raised, German-born Ingeborg submitted for her doctorate thesis defense. She was denied her chance for her defense because her mother was of the Jewish ancestry, making her an official "cross-breed". As such the Nazi regime forbid the university from proceeding with her defense, for "racial reasons".

She became one of the thousands of scholars and researchers banished from German academe, which at the time included many of the world's most prestigious research institutions, because of Jewish ancestry or opposition to Nazi policies. Many of them ended up suffering or dying in concentration camps. Rudolf Degkwitz, Syllm's professor, was imprisoned for objecting to euthanizing children. Syllm, however, was able to reach the United States and earned her medical degree from the old Women's Medical College of Pennsylvania in Philadelphia. Eventually she married a fellow physician named Samuel Mitja Rapoport, had a family, and moved back to Germany in the 1950s, where she achieved prominence in neonatology. Syllm-Rapoport, who is now 102 years old, might have remained just a doctor (if a very accomplished one) had not the present dean of the Hamburg medical school, Uwe Koch-Gromus, heard her story from a colleague of her son, Tom Rapoport, a Harvard cell biologist.

Determined to do what he could to mitigate this wrong, Koch-Gromus arranged Syllm-Rapoport's long-delayed defense. Despite failing eyesight, she brushed up on decades of developments in diphtheria research with the help of friends and the Internet. Koch-Gromus called the 45-minute oral exam given by him and two colleagues on 13 May in her Berlin living room "a very good test. Frau Rapoport has gathered notable knowledge about what's happened since then. Particularly given her age, she was brilliant."

Prospects and Limits For the LHC's Capabilities To Test String Theory 147

from the proving-it-maybe dept.
StartsWithABang writes: The Large Hadron Collider has just been upgraded, and is now making the highest energy collisions of any human-made machine ever. But even at 13 TeV, what are the prospects for testing String Theory, considering that the string energy scale should be up at around 10^19 GeV or so? Surprisingly, there are a number of phenomenological consequences that should emerge, and looking at what we've seen so far, they may disfavor String Theory after all.
