Researchers cast doubt on long-held theory of how bacteria become drug-resistant

Researchers have disproved a long-held theory about how some bacteria survive antibiotics and opened the door to new treatments to fight drug-resistant bugs, a study released Thursday said. Using a technique called microfluidics, scientists revealed that — contrary to the explanation that has held for more than 50 years —…

Startling discovery debunked: bacteria can’t survive on arsenic

Startling discovery debunked: bacteria can't survive on arsenic Nearly two years ago, a team of biologists claimed to have discovered new bacteria that not only could survive in an environment rich in arsenic, it could fold the toxic element into the very heart of its biochemistry – substituting to small…

Studies suggest that microbes can control our minds

An increasing amount of evidence is coming to light suggesting that human moods, emotions and perceptions can be influenced by the type and number of microscopic life forms inhabiting our gut, according to an article in Scientific American magazine. Scientists say a time may even come when we treat mental…

Study: Pneumonia bug gained drug resistance by swapping genes

PARIS, France — Bugs that cause childhood pneumonia and meningitis have evolved to evade vaccines by swapping bits of their genome with other bacteria, according to a study published Sunday. The findings, published in Nature Genetics, show how quickly these life-threatening pathogens can disguise themselves with borrowed genetic decoys, and…
