Packed cells may help explain why some cancerous tumors stay put while others break off and spread through the body.

Persistent anxiety can contribute to respiratory disorders, gastrointestinal problems, and heart disease. Treating anxiety with psychotherapy, medications, or a combination can reduce or relieve physiological distress.

Tactical Robotics’ Cormorant drone design allows it to navigate tight areas where a helicopter’s blades would get caught on the environment. The remote-controlled military drone can transport two injured people from a battle zone. The Israeli-based company believes the drone could one day also be used to inspect bridges, deliver medical supplies and spray crops.

It would include lots of data about law-abiding citizens, including their faces and voices.

A new report details a proposed biometrics strategy for the United Kingdom in which all collected biometrics are stored in one database.

Elon Musk Wants You to Watch ‘Do You Trust This Computer?’ in Memory of Stephen Hawking, and It’s Free.

Because “nothing will affect the future of humanity more than digital super-intelligence,” Elon Musk thinks you should watch Chris Paine’s artificial-intelligence movie “Do You Trust This Computer?” And, wouldn’t you know it, the film is streaming for free until later tonight.

Cerebral small vessel disease (SVD) is one of the most commonly associated causes of age-related dementia and stroke. New research, led by the University of Edinburgh, may have finally uncovered the mechanism by which SVD causes brain cell damage, as well as a potential treatment to prevent the damage, and possibly even reverse it.

SVD is thought to be responsible for up to 45 percent of dementia cases, and the vast majority of senior citizens are suspected of displaying some sign of the condition. One study strikingly found up to 95 percent of subjects between the ages of 60 and 90 displayed some sign of SVD when examined through MRI scans.

The new research set out to examine early pathological features of SVD and found that dysfunction in endothelial cells are some of the first signs of the disease’s degenerative progression. These are cells that line small blood vessels in the brain and, in early stages of SVD, they secrete a protein that impairs production of myelin, a compound essential for the protection of brain cells.

A team of scientists, looking to figure out how hardy little creatures known as archaea thrive in boiling, volcanic pools of sulfuric acid like they were hot tubs, may have uncovered the key to an anti-aging drug. By manipulating a so-called “super hero” protein common to both archaea and humans, the researchers found a way to “trick” cells into acting younger by keeping the DNA repairing process running much longer than usual.

In previous studies, the researchers examined how archaea have managed to survive in such harsh conditions for billions of years. Eventually they determined that a protein called ssB1 was responsible by helping the organisms repair damage to their DNA. The team says the real eureka moment came when they discovered that we humans have our own versions of this protein, hSSB1.
