A recent New York Times article described how China is stepping up efforts to lure home the top Chinese scholars who live and work abroad. The nation is already second only to the United States in the volume of scientific papers published, and it has, as Thomas Friedman pointed out, more student... Read More
A new study by a research team at Uppsala University shows how new functions can develop in an enzyme. This can explain, for example, how resistance to toxins can occur so simply. The findings are now being published in the Journal of Biological Chemistry.
Every biological being needs a large... Read More
Bodies piling up in Haiti pose a negligible infection risk to the public and don't need to be instantly buried or disinfected, the World Health Organization said on Monday in a report on the earthquake (PDF). Instead, relief workers should focus on treating the living.

Heat-loving bacteria found in the Arctic seabed have their origins in oil springs and the depths of the Earth's crust. This is the finding of a project supported by the Austrian Science Fund FWF, which used molecular biology to study "misplaced" bacteria such as these. The possibility that molec... Read More
Haiti’s next survival challenge lurks in its broken pipes, tainted wells and stagnant puddles: Water. If contaminated, it will spread disease. If stagnant, it will breed malarial mosquitoes. And if there’s no water at all, dehydration and death may follow.
“People can live without food for a ... Read More
And the debate rages on. We've posted several articles in recent months that have both said that strep is and isn't a cause for such disorders as OCD and/or tic syndromes like Tourette's.

Sludge from a distillery on Islay is set to be turned into green energy to power whisky production on the island.
Bruichladdich will next month install two anaerobic digesters – in which bacteria eat yeasty waste to produce methane – at a cost of about £300,000.
The methane gas will then be ... Read More

The flea’s mouthparts, perfectly adapted to puncturing the skin, slide in easily, and the tiny insect immediately begins sucking blood from its host.
But it doesn’t only suck blood – the flea’s saliva keeps blood from clotting. And riding along in that saliva are bacteria.
