An international team of biologists has discovered how specialized enzymes remodel the extremely condensed genetic material in the nucleus of cells in order to control which genes can be used. The discovery will be published in the print edition of the journal Nature on Feb. 4, 2016.
The Committee on Economic and Monetary Affairs of the European Parliament spent an hour and a half discussing bitcoin and virtual currencies on Monday, although more questions were asked than answered.

But a carbon nanotube coating (shown in clear jacket) replaces the tin-coated copper braid that serves as the outer conductor, ordinarily the heaviest component. Created by researchers at Rice University, the coating was tested by a collaborative group including NIST, which has more than 10 years of expertise in characterizing and measuring nanotu…bes. The coating, only up to 90 microns (millionths of a meter) in thickness, resulted in a total cable mass reduction of 50 percent (useful for lowering the weight of electronics in aerospace vehicles) and handled 10,000 bending cycles without affecting performance. And even though the coating is microscopically thin, the cable transmitted data with a comparable ability to ordinary cables, due to the nanotubes’ favorable electrical properties.

Everyone wants to build software that’s both usable and secure, yet the world is full of software that falters at this intersection. How does this happen? I experienced the disconnect firsthand, when the Chrome security team redid Chrome’s security UI to conform to best practices for usable security. In the process, we learned how hard it is to actually adhere to oft-cited wisdom about usable security when faced with real-world constraints and priorities. With a set of case studies, I’ll illustrate the limitations we encountered when trying to apply common wisdom to a browser with more than a billion users—and discuss what has actually worked for us in practice, which might work for other practitioners too.
Researchers at Harvard are working to identify the brain processes that make humans so good at recognising patterns. Their ultimate goals is to develop biologically-inspired computer systems for smarter AI. Computers inspired by the human brain could be used to detect network invasions, read MRI images, and even drive cars.

This just in: Aipoly Vision* — a free AI app that runs on your iPhone/iPad** (Android coming) and recognizes objects and colors — is now live on the App store, Aipoly Inc. co-founder Alberto Rizzoli just told me in an email.
Of course, I immediately downloaded the app, launched it on my iPhone 6s+, and tested it. It works spectacularly. Its voice names objects or colors in real time as a walk around and also displays objects’ names. I am blown away. Here’s a sample:

Not mentioned is that the roads become easier to replace instead of having to repave them.
The minister told a conference of transport authorities last week that the tenders for the “Positive Energy” initiative had already been issued and the tests on the panels would begin in the spring.
According to France’s Agency of Environment and Energy Management, 4m of solarised road is enough to supply one household’s electricity needs, apart from heating, and one kilometre will light a settlement with 5,000 inhabitants.
