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.

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.

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.
In the frigid depths of the Juan de Fuca tectonic plate off ... Read More
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.

An abundant type of bacteria that resides in the intestines is critical for keeping the immune system of the colon in check, according to a study published online today (December 23) in ScienceExpress.
The results add to the growing body of literature that commensal microbes in the gut are key ... Read More
It takes a lot more than doctoring to fight a polio outbreak in West Africa, particularly when distrust and cultural barriers cripple vaccination campaigns.
This week, a team of Michigan State University communications experts is heading for Nigeria to find better ways to get the crucial publ... Read More
It's that time of year again, when hidden bacteria lurks among us! It seems everybody has a cold, the flu or at least, a case of the sniffles.
And if you ride public transportation, you may wonder, as we did, just how germ-contaminated some of the handrails are. And if you're a parent, when y... Read More
