Observations made by NASA instruments onboard an Air Force satellite have shown that the boundary between the Earth’s upper atmosphere and space has moved to extraordinarily low altitudes.
MIT Engineers have developed carbon nanotubes into sensors for cancer drugs and other DNA-damaging agents inside living cells.

Archaeologists have recovered three lead bars which may originate from the third century before Christ, 39 meters under the sea off the north coast of Ibiza. One of the bars has Iberian characters on it. The lead originates from the mines of Sierra Morena in southern Spain.
HIV is so deadly largely because it evolves so rapidly. With a single virus as the origin of an infection, most patients will quickly come to harbor thousands of different versions of HIV, all a little bit different and all competing with one another to most efficiently infect that person’s cells. Now scientists have settled [...]

Researchers have devised a new research tool that could help unpick the complex cell interactions that lead to cancer and also allow social scientists to mine social networking sites such as Facebook for useful insights.
A growing number of adults know about the potential risk of swallowing magnets, but medical complications from magnets continue to be extensive worldwide and throughout childhood.
Data collected during several recent flybys of Titan by NASA’s Cassini spacecraft have put another arrow in the quiver of scientists who think the Saturnian moon contains active cryovolcanoes spewing a super-chilled liquid into its atmosphere. The information was released today during a meeting of the American Geophysical Union in San Francisco, Calif.

The first demonstration that a single adult stem cell can self renew in a mammal was reported by scientists. The transplanted adult stem cell and its differentiated descendants restored lost function to mice with hind limb muscle tissue damage.

Farming of fish in ocean cages is fundamentally harmful to wild fish, according to an essay in this week’s Conservation Biology. Using basic physics, the author explains how farm fish cause nearby wild fish to decline. The foundation of his paper is that higher density of fish promotes infection, and infection lowers the fitness of [...]

Researchers have discovered a direct link between disruption of a critical cellular housekeeping process and fatty liver disease, a condition that causes fat to accumulate in the liver. The findings might open new avenues for understanding and perhaps treating fatty liver disease, which is the most common form of liver disease in the Western world.
