Airline’s decision to end monkey transports will worsen shortage in research
Air France announced last week it will stop transporting nonhuman primates. The decision will create additional problems for biomedical research, which already faces increasing difficulty getting monkeys. Air France was the last major airline still carrying nonhuman primates as cargo, as other companies have
increasingly refused to do
so over the past 2 decades....
Shapeshifting microrobots can brush and floss teeth
A shapeshifting robotic microswarm may one day act as a toothbrush, rinse, and dental floss in one. The technology, developed by a multidisciplinary team at the University of Pennsylvania, is poised to offer a new and automated way to perform the mundane but critical daily tasks of brushing and flossing. It's a system that could be particularly valuable for those who lack the manual dexterity to...
New head of U.S. aid program for HIV/AIDS vows to refocus attention on the other, ‘silent’ pandemic

Researchers uncover life's power generators in the Earth's oldest groundwaters
An international team of researchers has discovered 1.2-billion-year-old groundwater deep in a gold- and uranium-producing mine in Moab Khotsong, South Africa, shedding more light on how life is sustained below the Earth's surface and how it may thrive on other planets.
Scientists uncover novel aspects of HIV infection by monitoring sugars at the surface of individual immune cells
HIV researchers have long been trying to identify the specific cells that the virus prefers to infect and hide in. They know that HIV favors a special type of immune cells called memory CD4 T cells. But these cells come in many flavors, and it has been difficult to ascertain exactly what makes one type of memory CD4 T cell more attractive to HIV than another.
As 'Run 3' begins, CERN touts discovery of exotic particles
The physics lab that's home to the world's largest atom smasher announced on Tuesday the observation of three new "exotic particles" that could provide clues about the force that binds subatomic particles together.
NASA: Contact lost with spacecraft on way to test moon orbit
NASA said Tuesday it has lost contact with a $32.7 million spacecraft headed to the moon to test out a lopsided lunar orbit, but agency engineers are hopeful they can fix the problem.
