The continuing controversy surrounding the announcement of strange bacteria deep in a California lake that can apparently survive on arsenic and even incorporate the element into its DNA is being held up as a shining example for how the scientific process works.
The latest to point this out a... Read More
A virus previously thought to be associated with chronic fatigue syndrome is not the cause of the disease, a detailed study has shown. The research shows that cell samples used in previous research were contaminated with the virus identified as XMRV and that XMRV is present in the mouse genome.

Scientists from the Florida campus of The Scripps Research Institute have identified a molecular interaction between a structural hepatitis C virus protein (HCV) and a protein critical to viral replication. This new finding strongly suggests a novel method of inhibiting the production of the vir... Read More

The World Health Organisation’s annual report on malaria was published on December 14th. As with the report on AIDS, the picture is one of cautious optimism. Malaria is still a huge killer. Nearly 800,000 people, most of them children, succumb each year. But what was, only a decade ago, a desult... Read More

Bacteria are able to develop resistance to antibiotics by co-opting the DNA of their natural enemies—viruses.
The battle between bacteria and bacteria-eating viruses has been going on for millions of years, with viruses attempting to replicate themselves by—in one approach—invading bacteria c... Read More
When the medical journalist Annie Murphy Paul’s first son was a toddler, she started wondering how personality traits are passed from one generation to the next. So she did what any reporter would do: she delved into the scientific literature and talked to investigators.
Then, in the course ... Read More
Whitehead Institute researchers have determined that heat shock protein 90 (Hsp90) can create heritable traits in brewer's yeast (Saccharomyces cerevisiae) by affecting a large portion of the yeast genome. The finding has led to the conclusion that Hsp90 has played a key role in genome evolution... Read More
A particular type of ancient rock art in Western Australia maintains its vivid colours because it is alive, researchers have found.
While some rock art fades in hundreds of years, the "Bradshaw art" remains colourful after at least 40,000 years.
Jack Pettigrew of the University of Queensla... Read More
We humans have a unique talent for contaminating pristine environments. We put millions of tonnes of pollutants into the atmosphere every year. We poison our soils, lakes, rivers and streams with chemical and radioactive waste. We spill oil into our seas. We fill the Pacific and Atlantic oceans ... Read More
Researchers are trying to uncover the secrets of one of nature's most primitive immune systems by studying how bacteria incorporate foreign DNA from invading viruses into their own regulatory processes.
Thomas Wood of the Texas AnM University has shed light on how bacteria have throughout the... Read More
There is a thriving realm of mysterious microbes of potential importance to the global carbon budget hidden beneath the sea floor near where the Earth's crust is being pulled apart, according to new evidence from deep-sea explorers.

Let's be honest, chewing on the rock-hard roof of a gingerbread house that's been sitting around since the beginning of Advent is enough to make anyone a little queasy.
But there's another reason to steer clear of stale gingerbread if you bought a decorative cookie home at a Whole Foods Marke... Read More
A seemingly unremarkable ocean microbe turns out to be a multitasker — it can not only photosynthesize, but can also produce large amounts of hydrogen, opening up a potential way to make the gas cheaply for fuel.
The single-celled cyanobacterium Cyanothece 51142 can make hydrogen in air, Hima... Read More
The humanitarian coordinator for the United Nations in Haiti, Nigel Fisher, says a decline is taking place here in the mortality rate from cholera, which has killed more than 2,400 people and affected more than 100,000 in the Caribbean nation over the last two months.
