Machine learning provides the underlying oomph to many of Google’s most-loved applications. In fact, more than 100 teams are currently using machine learning at Google today, from Street View, to Inbox Smart Reply, to voice search.

But one thing we know to be true at Google: great software shines brightest with great hardware underneath. That’s why we started a stealthy project at Google several years ago to see what we could accomplish with our own custom accelerators for machine learning applications.

The study, published in the journal Nature, relies on data on past ice levels of the Totten Glacier in East Antarctica to evaluate the rate of melting. Without intense efforts to stem man-made global warming, the glacier’s melting process could cross the point of no return within the next 100 years, according to report. The result would add more than 6.6 feet (2 meters) of sea level rise over the coming several centuries, in addition to several feet of rise from other sources.

“The evidence coming together is painting a picture of East Antarctica being much more vulnerable to a warming environment than we thought,” said study author Martin Siegert, an Imperial College London researcher, in a press release. “This is something we should worry about.”

CHARLOTTESVILLE, Va., May 17, 2016 — A gene that scientific dogma insists is inactive in adults actually plays a vital role in preventing the underlying cause of most heart attacks and strokes, researchers at the University of Virginia School of Medicine have determined. The discovery opens a new avenue for battling those deadly conditions, and it raises the tantalizing prospect that doctors could use the gene to prevent or delay at least some of the effects of aging.

“Finding a way to augment the expression of this gene in adult cells may have profound implications for promoting health and possibly reversing some of the detrimental effects with aging,” said researcher Gary K. Owens, PhD, director of UVA’s Robert M. Berne Cardiovascular Research Center.

Hmmmmm.

“We had analysts crawling all over that,” says Chappell of the Hold Security cache. “Quickly it was clear that a lot of those were from previous breaches.”

Anyone using this tool would have had a rapid assessment of their potential exposure. If breached data turns out to be new, the next task is to understand how it might have ended up in the hands of criminals. There are several sources for breached data including straight database theft but also phishing attacks and malware campaigns, each with its own dynamics and set of business implications.

“Instant responders are in a horrible position. They have to work out whether it [the breach] is genuine or not — Google is not effective,” says Chappell.

New graphene transistor makes for a faster processor.

Scientists have developed a new type of graphene-based transistor and using modelling they have demonstrated that it has ultralow power consumption compared with other similar transistor devices. The findings have been published in a paper in the journal Scientific Reports. The most important effect of reducing power consumption is that it enables the clock speed of processors to be increased. According to calculations, the increase could be as high as two orders of magnitude.

“The point is not so much about saving electricity — we have plenty of electrical energy. At a lower power, electronic components heat up less, and that means that they are able to operate at a higher clock speed — not one gigahertz, but ten for example, or even one hundred,” says the corresponding author of the study, the head of MIPT’s Laboratory of Optoelectronics and Two-Dimensional Materials, Dmitry Svintsov.

The oldest space dust yet found on Earth suggests that the ancient atmosphere of Earth had significantly more oxygen than previously thought, a new study finds.

Although oxygen gas currently makes up about one-fifth of Earth’s air, there was at least 100,000 times less oxygen in the primordial atmosphere, researchers say. Oxygen easily reacts with other molecules, which means it readily gets bound to other elements and pulled from the atmosphere.

Previous research suggests that significant levels of oxygen gas started permanently building up in the atmosphere with the Great Oxidation Event, which occurred about 2.4 billion years ago. This event was most likely caused by cyanobacteria — microbes that, like plants, photosynthesize and release oxygen. [Infographic: Earth’s Atmosphere Top to Bottom].
