Microsoft: No More 'Patch Tuesday' For Windows 10 Home Users

Slashdot - Tue, 05/05/2015 - 6:35pm
citpyrc writes: According to the Register, Microsoft is making some changes to how it rolls out updates in Windows 10. Home users will receive updates as they come out, rather than queueing them all up on "patch Tuesday." Business users will have the option to set their own update cycle, so they can see if any of the patches accidentally break anything for home users before trying them out. There will also be an optional peer-to-peer updating mechanism for Windows 10. Microsoft announced a service called Advanced Threat Analytics, which employs various machine learning techniques to identify malware on a network. As a premium service, top-dollar customers can pay for Microsoft to monitor black-hat forums and alert the company if any of its employees' identities are stolen.

Who benefits from a catheter -- and who doesn't? New guide aims to protect patients

Science Daily - Tue, 05/05/2015 - 6:25pm
What's the only thing worse than having a urinary catheter when you're in the hospital? Having one and getting a urinary tract infection -- or worse -- as a result. Now, a new detailed guide gives doctors and nurses information to help decide which hospital patients may benefit from a urinary catheter -- and which ones don't.

Researchers observe the moment when a mind is changed

Science Daily - Tue, 05/05/2015 - 6:25pm
Researchers studying how the brain makes decisions have, for the first time, recorded the moment-by-moment fluctuations in brain signals that occur when a monkey making free choices has a change of mind. This basic neuroscience discovery will help create neural prostheses that can withhold moving a prosthetic arm until the user is certain of their decision, thereby averting premature or inopportune movements.

Redesigned systems may increase access to MRI for patients with implanted medical devices

Science Daily - Tue, 05/05/2015 - 6:25pm
New technology may extend the benefits of magnetic resonance imaging to many patients whose access to MRI is currently limited. A redesign of the wire at the core of the leads that carry signals between implanted medical devices and their target structures significantly reduces the generation of heat that occurs when standard wires are exposed to the radiofrequency (RF) energy used in MRI.

Astronomers unveil farthest galaxy, more than 13 billion years in the past

Science Daily - Tue, 05/05/2015 - 6:25pm
Astronomers have pushed back the cosmic frontier of galaxy exploration to a time when the universe was only 5 percent of its present age. Age and distance are vitally connected in any discussion of the universe. The light we see from our Sun takes just eight minutes to reach us, while the light from distant galaxies we see via today's advanced telescopes travels for billions of years before it reaches us -- so we're seeing what those galaxies looked like billions of years ago.

Compact light source improves CT scans

Science Daily - Tue, 05/05/2015 - 6:24pm
The recently developed Compact Light Source (CLS) -- a commercial X-ray source -- enables computer tomography scans that reveal more detail than routine scans performed at hospitals today. The new technology could soon be used in preclinical studies and help researchers better understand cancer and other diseases.

Extreme Exoplanet Volcanism Possibly Detected On 55 Cancri E

Slashdot - Tue, 05/05/2015 - 5:52pm
astroengine writes: Using data from NASA's Spitzer Space Telescope, astronomers have revealed wild atmospheric changes on a well studied exoplanet — changes that they suspect are driven by extreme volcanic activity. Over a period of two years, the team, led by University of Cambridge researchers, noted a three-fold change in temperature on the surface of 55 Cancri e. The super-Earth planet orbits a sun-like star 40 light-years away in the constellation of Cancer. It is twice the size of Earth and 8-times our planet's mass. 55 Cancri e is well-known to exoplanet hunters as the "diamond planet" — a world thought to be carbon-rich, possibly covered in hydrocarbons. But this new finding, published in the arXiv pre-print service, has added a new dimension to the planet's weird nature. "This is the first time we've seen such drastic changes in light emitted from an exoplanet, which is particularly remarkable for a super-Earth," said co-author Nikku Madhusudhan, of Cambridge's Institute of Astronomy, in a press release. "No signature of thermal emissions or surface activity has ever been detected for any other super-Earth to date."

Molecular link between high glucose, metabolic disease may offer new strategies to control diabetes

Science Daily - Tue, 05/05/2015 - 5:17pm
Scientists say they've discovered a cause-and-effect link between chronic high blood sugar and disruption of mitochondria, the powerhouses that create the metabolic energy that runs living cells. The discovery sheds light on a long-hidden connection and, they say, could eventually lead to new ways of preventing and treating diabetes.
