The feared Legionella pneumophila bacteria is responsible for legionellosis, an infectious disease that can lead to pneumonia. In order to infect us, this pathogen has developed a complex method enabling it to camouflage itself and go unnoticed in our cells, thus avoiding these acting against the infectious bacteria.

Online retail titan Amazon announced Thursday it is expanding sales of its Kindle tablet computers to "over 170 countries and territories around the world," and its Appstore in nearly 200 countries.

Few have explored the remote volcanic islands of the Galapagos archipelago, an otherworldly landscape inhabited by the world's largest tortoises and other fantastical creatures that inspired Charles Darwin's theory of evolution.

Harvard physicists have developed a novel technique that can detect molecular variants in chemical mixtures – greatly simplifying a process that is one of the most important, though time-consuming, processes in analytical chemistry. Source: Harvard University - Discipline: Chemistry

Scientists have reversed behavioral and brain abnormalities in adult mice that resemble some features of schizophrenia by restoring normal expression to a suspect gene that is over-expressed in humans with the illness. Targeting expression of the gene Neuregulin1, which makes a protein important for brain development, may hold promise for treating at least some patients with the brain disorder, sa Source: NIH/National Institute of Mental Health - Discipline: Neuroscience

Scientists find gene behind striking coloration

Researchers at Johns Hopkins have unraveled the molecular foundations of cocaine's effects on the brain, and identified a compound that blocks cravings for the drug in cocaine-addicted mice. The compound, already proven safe for humans, is undergoing further animal testing in preparation for possible clinical trials in cocaine addicts, the researchers say. "It was remarkably serendipitous that Source: Johns Hopkins Medicine - Discipline: Neuroscience

In the tropics at heights more than 10 miles above the surface, the prevailing winds alternate between strong easterlies and strong westerlies roughly every other year. This slow heartbeat in the tropical upper atmosphere, referred to as the quasibiennial oscillation (QBO), impacts the winds and chemical composition of the global atmosphere and even the climate at Earth's surface.

What is it about Oklahoma's geographical location that causes increased susceptibility to tornadoes? How can residents of ‘tornado valley’ better protect themselves against these rampant acts of Mother Nature?The Tree Health and Plant Biosecurity Expert Taskforce have just issued their first report with recommendations to combat what they call an “unprecedented threat” from non-native pests and diseases. The Veterinary Medicines Directorate has issued the pharmaceutical company MSD Animal Health a provisional licence to provide the new ‘Bovilis SBV’ vaccine to UK farmers. They will be the first in the EU to access the vaccine.Professor Hugh Griffiths, the winner of the Institution of Engineering and Technology's A F Harvey Prize, is receiving his prize tonight - £300, 000 to continue his work on bistatic radar and using FM radio waves and TV signals as radar. He joins Quentin Cooper in the studio. . .

Chinese scientists trace the rare white colouration in Bengal tigers to a single change in a gene that affects a host of animals, including humans.
