Smart flies can match odd scents to sweet treats based on time of day

Science Daily - Thu, 28/05/2015 - 4:41pm
Flies might be smarter than you think. New research shows fruit flies know what time of day it is. What's more, the insects can learn to connect different scents with the sweet reward of sugar, depending on the hour: menthol in the morning and mushrooms in the afternoon.

Scientists discover key to what causes immune cell migration to wounds

Science Daily - Thu, 28/05/2015 - 4:41pm
Immune cells play an important role in the upkeep and repair of our bodies, helping us to defend against infection and disease. Until now, how these cells detect a wounded or damaged site has largely remained a mystery. New research has identified the triggers which lead these cells to react and respond in cell repair.

Public raises alarm about ineffectiveness of some Montagu's harrier conservation measures

Science Daily - Thu, 28/05/2015 - 4:40pm
A citizen science program reveals the protection measures for the Montagu's harrier in the cereal crop season in France to be ineffective if nests are not protected to decrease predation after harvesting. A new study proposes fencing off the nests as a way of mitigating the damage and optimizing conservation efforts in different areas.

Health factors influence ex-prisoners' chances of returning to jail

Science Daily - Thu, 28/05/2015 - 4:40pm
Ex-prisoners with a history of risky drug use, mental illness or poverty are more likely to end up back behind bars. Those who are obese, are chronically ill or have attempted suicide are more likely to remain in the community. These are some of the findings from an exploratory study into health-related factors that could be used to predict whether a person released from prison will end up in custody again.

Acquiring 'perfect' pitch may be possible for some adults

Science Daily - Thu, 28/05/2015 - 4:39pm
If you're a musician, this sounds too good to be true: psychologists have been able to train some adults to develop the prized musical ability of absolute pitch, and the training's effects last for months.

Sleep quality influences cognitive performance of autistic, neurotypical children

Science Daily - Thu, 28/05/2015 - 4:38pm
One night of poor sleep significantly decreases performance on intelligence tests in children with autism spectrum disorder (ASD) and also in neurotypical children (without ASD). The researchers observed the EEG measures of 13 autistic children and 13 neurotypical children (children with a mean age of 10 years old without an intellectual deficiency or sleep problem and who were not on medication) and found that disruptions in protective brain waves during sleep are associated with lower results on verbal IQ tests.

New target for treating drug-resistant melanoma found

Science Daily - Thu, 28/05/2015 - 4:38pm
A new study explains why some melanoma tumors are resistant to BRAF inhibitor treatment. Melanoma is the deadliest form of skin cancer, killing more than 8,000 people in the U.S. each year. Approximately 50 percent of melanoma tumors are driven by mutations in the BRAF gene, and patients with these tumors are prescribed BRAF inhibitors.

Bladder cells regurgitate bacteria to prevent UTIs

Science Daily - Thu, 28/05/2015 - 4:38pm
Bladder cells have a highly effective way to combat E. coli bacteria that cause urinary tract infections (UTIs), researchers have found. They do to the bacteria what we could do to having indigestion problems: vomiting to rid the stomach of harmful substances.

How a Scientist Fooled Millions With Bizarre Chocolate Diet Claims

Slashdot - Thu, 28/05/2015 - 4:11pm
__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."

A Tool For Analyzing H-1B Visa Applications Reveals Tech Salary Secrets

Slashdot - Thu, 28/05/2015 - 3:28pm
Tekla Perry writes: The golden age of engineers is not over,' says a French software engineer who developed a tool for mining U.S. Department of Labor visa application data, but, he says, salaries appear to be leveling off. Indeed, salary inflation for software engineers and other technical professionals at Google and Facebook has slowed dramatically, according to his database, and Airbnb and Dropbox pay is down a little, though Netflix pay is through the roof. The data also shows that some large companies appear to be playing games with titles to deflate salaries, and Microsoft is finally offering technology professionals comparable salaries to Apple and Google. There's a lot more to be discovered in this interactive database, and researchers are getting ready to mine it.

How Tesla Batteries Will Force Home Wiring To Go Low Voltage

Slashdot - Thu, 28/05/2015 - 2:47pm
CIStud writes with a story at CEPro suggesting that solar power and home batteries like Tesla's PowerWall "will force the reinvention of home wiring from primarily AC high voltage to DC home-run low voltage to reduce power conversion loss," writing "To avoid the 20% to 40% power loss when converting from DC to AC, home wiring will have to convert to home-run low-voltage, and eventually eliminate the need for high-voltage 110V electrical wiring." As a former full-time Airstream dweller, I can attest to the importance of DC appliances when dealing with batteries.

Astronomy: Link between mergers and supermassive black holes with relativistic jets

Science Daily - Thu, 28/05/2015 - 2:41pm
In the most extensive survey of its kind ever conducted, a team of scientists have found an unambiguous link between the presence of supermassive black holes that power high-speed, radio-signal-emitting jets and the merger history of their host galaxies. The results lend significant weight to the case for jets being the result of merging black holes.
