Researchers say two of the four known varieties of the HIV-1 virus originated in western lowland gorillas in Cameroon. Unlike a variety that jumped to humans from chimpanzees and caused the global AIDS pandemic, the gorilla-derived version has remained in Africa, they say.
Researchers Discover How Bacteria 'Steal' Genetic Information
Bacteria can bulk up immunity to invading viruses by "stealing" and using the invader's genetic information, researchers say. Finding could lead to treatment for human diseases and genetic condition.
Light Imaged As Particle And Wave For The First Time
Einstein was right, experiment shows; light can be both a particle and a wave -- at the same time. Scientists use advanced electron microscope to capture an image of light's dual nature.
Stunning Cryo-Transmission Electron Microscopy Image Reveals Innards Of Ultra-Small Bacteria
Scientists say they've taken a first look at ultra-small bacteria, the existence of which has generated lots of debate. The tiny bacteria is thought to be as small as life on Earth can be.

Parasite Found To Be Carried By Florida Snails Is Rare But Can Be Deadly
Parasite found in invasive snails in Florida is a threat to both humans and animals, scientists say. Spread of the parasite in Florida is more extensive than previously thought, they find.
Alaskan Village Faces Relocation Because Of Climate Change
Shrinking sea ice from global warming threatens residents of small Alaskan village. Talks of relocation generate debate over who would pay the moving costs.
New Electrolyte Solves Problem Of Limited Battery Power
