Alzheimer's drug prescribed off-label could pose risk for some

Science Daily - Sat, 25/02/2017 - 3:21pm
Donepezil, a medication that is approved to treat people with Alzheimer's disease, should not be prescribed for people with mild cognitive impairment without a genetic test. Researchers discovered that for people who carry a specific genetic variation -- the K-variant of butyrylcholinesterase, or BChE-K -- donezpezil could accelerate cognitive decline.

Antibiotics used to treat cystic fibrosis increases risk of permanent hearing loss

Science Daily - Sat, 25/02/2017 - 3:21pm
A powerful class of antibiotics provides life-saving relief for people with cystic fibrosis; however, a new study for the first time reveals the levels at which high cumulative dosages over time significantly increases the risk of permanent hearing loss in these patients. The study suggests physicians who treat patients with cystic fibrosis may be able to consider alternative strategies for treating the symptoms of respiratory infections associated with CF.

Al Gore Sells $29.5 Million In Apple Stock

Slashdot - Sat, 25/02/2017 - 1:00pm
An anonymous reader quotes a report from AppleInsider: A U.S. Securities and Exchange Commission filing on Friday reveals Apple board member Al Gore this week sold 215,437 shares of Apple stock (APPL) worth about $29.5 million. Gore's stock sale, which was accomplished in multiple trades ranging from $136.4 to $137.12 on Wednesday, nearly matches a $29.6 million purchase of Apple shares made in 2013. When Gore bought the stock batch more than four years ago, he exercised Apple's director stock option to acquire 59,000 shares at a price of about $7.48 per share, costing him approximately $441,000. This was pre-split AAPL, so shares were valued at $502.68 each. Following today's sale, Gore owns 230,137 shares of Apple stock worth $31.5 million at the end of trading on Friday.

Arizona Bill Would Make Students In Grades 4-12 Participate Once In An Hour of Code

Slashdot - Sat, 25/02/2017 - 10:00am
theodp writes: Christopher Silavong of Cronkite News reports: "A bill, introduced by [Arizona State] Sen. John Kavanagh [R-Fountain Hills] would mandate that public and charter schools provide one hour of coding instruction once between grades 4 to 12. Kavanagh said it's critical for students to learn the language -- even if it's only one session -- so they can better compete for jobs in today's world. However, some legislators don't believe a state mandate is the right approach. Senate Bill 1136 has passed the Senate, and it's headed to the House of Representatives. Kavanagh said he was skeptical about coding and its role in the future. But he changed his mind after learning that major technology companies were having trouble finding domestic coders and talking with his son, who works at a tech company." According to the Bill, the instruction can "be offered by either a nationally recognized nonprofit organization [an accompanying Fact Sheet mentions tech-backed Code.org] that is devoted to expanding access to computer science or by an entity with expertise in providing instruction to pupils on interactive computer instruction that is aligned to the academic standards."

Scientists Teach Bees How To Play Soccer

Slashdot - Sat, 25/02/2017 - 7:00am
Clint Perry, a biologist who studies the evolution of cognition in insects at Queen Mary University of London, and his colleagues have released the results of a creative new experiment in which they essentially taught bumblebees how to play "bee soccer." "The insects' ability to grasp this novel task is a big score for insect intelligence, demonstrating that they're even more complex thinkers than we thought," reports Smithsonian. From the report: For the study, published in the February 23 issue of Science, researchers gave a group of bees a novel goal (literally): to move a ball about half their size into a designated target area. The idea was to present them with a task that they would never have encountered in nature. Not only did the bees succeed at this challenge -- earning them a sugary treat -- but they astonished researchers by figuring out how to meet their new goal in several different ways. Some bees succeeded at getting their ball into the goal with no demonstration at all, or by first watching the ball move on its own. But the ones that watched other bees successfully complete the game learned to play more quickly and easily. Most impressively, the insects didn't simply copy each other -- they watched their companions do it, then figured out on their own how to accomplish the task even more efficiently using their own techniques. The results show that bees can master complex, social behaviors without any prior experience -- which could be a boon in a world where they face vast ecological changes and pressures.

Fasting Diet 'Regenerates Diabetic Pancreas'

Slashdot - Sat, 25/02/2017 - 3:30am
According to a new study published in the journal Cell, a certain type of fasting diet can trigger the pancreas to regenerate itself. Of course, the researchers advise people not to try this without medical advice. BBC reports: In the experiments, mice were put on a modified form of the "fasting-mimicking diet." It is like the human form of the diet when people spend five days on a low calorie, low protein, low carbohydrate but high unsaturated-fat diet. It resembles a vegan diet with nuts and soups, but with around 800 to 1,100 calories a day. Then they have 25 days eating what they want -- so overall it mimics periods of feast and famine. Previous research has suggested it can slow the pace of aging. But animal experiments showed the diet regenerated a special type of cell in the pancreas called a beta cell. These are the cells that detect sugar in the blood and release the hormone insulin if it gets too high. There were benefits in both type 1 and type 2 diabetes in the mouse experiments. Type 1 is caused by the immune system destroying beta cells and type 2 is largely caused by lifestyle and the body no longer responding to insulin. Further tests on tissue samples from people with type 1 diabetes produced similar effects.

Appeals Court: You Have the Right To Film the Police

Slashdot - Sat, 25/02/2017 - 2:05am
An anonymous reader quotes a report from Ars Technica: A divided federal appeals court is ruling for the First Amendment, saying the public has a right to film the police. But the 5th U.S. Circuit Court of Appeals, in upholding the bulk of a lower court's decision against an activist who was conducting what he called a "First Amendment audit" outside a Texas police station, noted that this right is not absolute and is not applicable everywhere. The facts of the dispute are simple. Phillip Turner was 25 in September 2015 when he decided to go outside the Fort Worth police department to test officers' knowledge of the right to film the police. While filming, he was arrested for failing to identify himself to the police. Officers handcuffed and briefly held Turner before releasing him without charges. Turner sued, alleging violations of his Fourth Amendment right against unlawful arrest and detention and his First Amendment right of speech. The 2-1 decision Thursday by Judge Jacques Wiener is among a slew of rulings on the topic, and it provides fresh legal backing for the so-called YouTube society where people are constantly using their mobile phones to film themselves and the police. A dissenting appellate judge on the case -- Edith Brown Clement -- wrote Turner was not unlawfully arrested and that the majority opinion from the Texas-based appeals court jumped the gun to declare a First Amendment right here because one "is not clearly established."

ZeniMax Files Injunction To Stop Oculus From Selling VR Headsets

Slashdot - Sat, 25/02/2017 - 1:25am
ZeniMax, the parent company of Fallout and Skyrim developer Bethesda, has filed for an injunction against virtual-reality company Oculus over the recent stolen technology case. The company had accused Oculus of stealing VR-related code, and was subsequently awarded $500 million by a Dallas court earlier this month. ZeniMax has now filed additional papers against Oculus, requesting that Oculus' products using the stolen code be removed from sale. GameSpot reports: Specifically, ZeniMax is seeking to block sales of its mobile and PC developer kits, as well as technology allowing the integration of Oculus Rift with development engines Unreal and Unity, reports Law360. If the injunction isn't granted, ZeniMax wants a share of "revenues derived from products incorporating its intellectual properties," suggesting a 20 percent cut for at least 10 years. ZeniMax argues the previous settlement of $500 million is "insufficient incentive for [Oculus] to cease infringing." Oculus, meanwhile, says that "ZeniMax's motion does not change the fact that the [original] verdict was legally flawed and factually unwarranted. We look forward to filing our own motion to set aside the jury's verdict and, if necessary, filing an appeal that will allow us to put this litigation behind us," the virtual reality company stated.
