A study dating the age of more than 1 million single-letter variations in the human DNA code reveals that most of these mutations are of recent origin, evolutionarily speaking. These kinds of mutations change one nucleotide – an A, C, T or G – in the DNA sequence. Over 86 percent of the harmful protein-coding mutations of this type arose in humans just during the past 5,000 to 10,000 years.

Some of the remaining mutations of this nature may have no effect on people, and a few might be beneficial, according to the project researchers. While each specific mutation is rare, the findings suggest that the human population acquired an abundance of these single-nucleotide genetic variants in a relatively short time. (more…)

‘Visual Studio 11’ Beta and .NET Framework 4.5 Beta Make Software Development Fast, Collaborative and Focused

*New version of Microsoft’s flagship development environment simplifies common workflows, reduces user interface complexities and streamlines application lifecycle management, improving collaboration for developers and teams.*

REDMOND, Wash. — Designing software, creating code and then bringing a product to market is an incredibly complex affair — and it’s becoming more complex by the minute as software users demand greater integration between applications, across devices and among services. To help integrate cross-functional teams and help developers accomplish goals more efficiently, Microsoft will release code-named “Visual Studio 11” Beta and .NET Framework 4.5 Beta on Feb. 29.

“Visual Studio 11” is an integrated solution that helps individuals and development teams of any size to be productive and focused, to collaborate seamlessly with colleagues, and to turn their ideas into exceptional and compelling applications. (more…)

A U physicist will help determine if neutrinos can outrace light

Back in 2007, a physics experiment clocked elusive subatomic particles called neutrinos going faster than light.

That wasn’t supposed to happen. If the speed of light in a vacuum—denoted “c” by physicists—isn’t the universal speed limit, it would mean that Einstein put the wrong number in his famous E=mc² equation.

University of Minnesota physicist Marvin Marshak was part of the experiment, called MINOS. It clocked beams of neutrinos shot from Fermilab, a national physics lab near Chicago, to a detector 457 miles away in the Soudan Underground Laboratory in northern Minnesota. (more…)

Health benefits of walnuts have been known since time immemorial. Hippocrates and Avicenna mentioned them in the treatment of various diseases. In addition, the ancients thought that they stimulate mental activity. Anna Protsenko, a nutritionist, told MedPulse.ru.

“Walnuts contain a great deal of minerals,” the expert explains. “They include iron, copper, cobalt, potassium, sodium, phosphorus, magnesium, calcium, and iodine. Many of them are antioxidants.
