Strange coral-like growths at the bottom of Pavilion Lake in British Columbia have been out of the reach of scientists until now with the addition of new submersible technology. The growths might hold the key to life beyond Earth.
Climate Change Could Severely Impact California's Unique Native Plants

California's endemic plants -- those found nowhere else in the world -- could disappear from their natural ranges as a result of global warming and associated changes in rainfall, according to a new study. In general, plants will move northward and towards the coast, and in southern California, upward into mountain refugia, highlighting the need to protect these refugia and corridors between them. One big question remains: Can plants migrate fast enough to escape warming's effects?
Extreme Weather Events Can Unleash A 'Perfect Storm' Of Infectious Diseases, Research Study Says

Scientists have found the first clear example of how climate extremes, such as the increased frequency of droughts and floods expected with global warming, can create conditions in which diseases that are tolerated individually may converge and cause mass die-offs of livestock or wildlife.
New Invention Effectively Kills Foodborne Pathogens In Minutes

Researchers have developed an effective technology for reducing contamination of dangerous bacteria on food. The new antimicrobial wash rapidly kills Salmonella and E. coli O157:H7 on foods ranging from fragile lettuce to tomatoes, fruits, poultry products and meats. It is made from inexpensive and readily available ingredients that are recognized as safe by the US Food and Drug Administration.
To Find Out What's Eating Bats, Biologist Takes To Barn Rooftops

Bloodsucking pests like bat fleas and bat flies may not sound very appealing to the rest of us, but to many biologists they are considered among the most successful creatures evolution has ever produced. Researchers aim to provide a clearer picture of how potential disease vectors adapt to bats. This work may shed light on White Nose Syndrome, which has killed tens of thousands of bats in the northeastern U.S. and which some feel may parallel the Colony Collapse Disorder that has devastated honey bee colonies in recent years.
Newly Identified Role For 'Power Plants' In Human Cells Could Lead To Targeted Therapies
21:47 24-06-2008; source: www.sciencedaily.com
Scientists have determined that human cells are able to shift important gene products into their own mitochondria, considered the power plants of cells. The finding could eventually lead to therapies for dozens of diseases. The gene products, known as tRNAs, assemble amino acids for the production of proteins within mitochondria. If the mitochondrial tRNA genes are defective or missing, and proteins are not manufactured, the mitochondria are unable to generate adequate energy.
