Scientists are reporting dramatic new real-world evidence supporting the idea that hand washing can prevent the spread of water-borne disease. It appears in a new study showing a connection between fecal bacteria contamination on hands, fecal contamination of stored drinking water, and health in... Read More

The field of biosensing has recently found an unlikely partner in the quest for increased sensitivity: coffee rings. The next time you spill your coffee on a table, look at the spot left after the liquid has evaporated, and you'll notice it has a darker ring around its perimeter that contains a ... Read More
Particular parvoviruses normally infect rodents, but they are also infectious for human cells. However, they do not cause any disease symptoms in humans. Most importantly, these viruses have an astonishing property: They kill infected tumors cells without causing any damage to healthy tissue. Th... Read More
A new hip-hop show about evolution is scientifically accurate, and even more fun than a lecture.
Extremely low birthweight infants (ELBW) who received feedings supplemented with probiotics had better weight gain than infants who were not given the supplements, according to a randomized, controlled, double-blind study presented May 1 at the Pediatric Academic Societies (PAS) annual meeting i...

A group of college students has turned a salad spinner into a rudimentary centrifuge that medical clinics in developing countries could use to manually separate blood without electricity. They built it for about $30—including the spinner—using plastic lids, cut-up combs, yogurt containers, and a... Read More

Industrial manufacturing - a process that's given us products ranging from Model T's autos to cheap transistor radios - may have gotten a toehold in the research lab now. Given the commercial potential inherent here, I wouldn't be surprised to see an IPO from the developers of this technology i... Read More
A start-up company has broken ground on a Texas pilot plant that is supposed to produce ethanol and diesel in a radical new way: with an organism that sweats fuel. Read More
Here's an interesting blog post that compares E.coli's transcriptional regulatory network to Linux:
"We refer to DNA as “the book of life”; some geeks refer to it as the “operating system of life”. Just like in a computer’s operating system, DNA contains all the instructions on how to “execut... Read More

The cellular arrangement of purple bacteria could be adapted for use in solar panels and other energy conversion devices to offer a more efficient way to garner energy from the sun, according to a physicist at the University of Miami.
Purple bacteria were among the first life forms on Earth. ... Read More
The results are not finalized, but Texas AgriLife Extension Service wheat specialists and Texas AgriLife Research wheat breeders believe the crop is being damaged this year by a new or different race of stripe rust.
Because this winter and early spring were cooler and wetter than normal, cond... Read More
Hong Kong is an affluent subtropical city with a well-developed healthcare infrastructure but an intermediate TB burden. Declines in notification rates through the 1960s and 1970s have slowed since the 1980s to the current level of around 82 cases per 100 000 population. We studied the transmiss... Read More
In the depths of a former copper mine in Northern California dwell what may be the smallest, most stripped-down forms of life ever discovered.
The microbes — members of the domain of one-celled creatures called Archaea — are smaller than other known microorganisms, rivaled in size only by a m... Read More
Fetuses aren't as defenceless as they seem - they may be armed to fight off viruses long before birth.
It was thought that fetal immune cells were too immature to be useful and that fetuses and newborns relied on antibodies provided by their mothers. Now David Vermijlen at the Institute for M... Read More
Aphids can be a gardener’s nightmare. But they may be an evolutionary biologist’s dream. Because they’re pioneers in the history of life on Earth. For one thing, they’re now the only known animals to produce the chemical pigments called carotenoids, which help in cell repair and immunity. It’s t... Read More
