A diverse range of life forms exists deep below Earth's surface, scientists have concluded, but they survive at an incredibly slow pace.
Long-lived bacteria, reproducing only once every 10,000 years, have been found in rocks 2.5km (1.5 miles) below the ocean floor that are as much as 100 mill... Read More
Everywhere you go, the trillions of microbes in your gut go too. And that's a comforting thought. Because according to a new study, a more diverse population of intestinal bacteria is linked to better health. The work is in the journal Nature. [Emmanuelle Le Chatelier et al, Richness of human gu... Read More
People who have less diversity in their intestinal microbiomes tend to be heavier and have more inflammation and metabolic dysfunction than those who have a more robust portfolio of gut bacteria, researchers found.
In an analysis of data from the European consortium MetaHIT, about a quarter o... Read More
What types of microbes do mothers transmit to their newborns and how universal is maternal microbial transmission throughout animals, including from your mother?
The sterile womb paradigm is an enduring premise in biology that human infants are born sterile. Recent studies suggest that infant... Read More
Based on a Twitter conversation with two microbiology educators, I share a story of how (through a survey) I encourage students to look deeply at their study strategies and promote "ownership" in their classroom experience. Read More
Researchers from the Perelman School of Medicine at the University of Pennsylvania demonstrate for the first time that the immune system influences the skin microbiome. A new study found that the skin microbiome -- a collection of microorganisms inhabiting the human body -- is governed, at least... Read More
This is one the most extraordinary and convoluted evolutionary tales that I have ever heard. It’s the origin story of a group of viruses called REVs. It’s the tale of how naturalists and scientists inadvertently created a bird virus out of a mammalian one through zoo-collecting and medical resea... Read More
A widespread die-off of bottlenose dolphins off the Mid-Atlantic Coast — the worst of its kind in more than a quarter-century — almost certainly is the work of a virus that killed more than 740 dolphins in the same region in 1987 and 1988, marine scientists said Tuesday.
Since the beginning o... Read More
A botulism scare that damaged New Zealand's international reputation for providing top quality and safe dairy products was likely a false alarm.
New Zealand government officials said Wednesday they had found no sign of botulism bacteria after retesting ingredients used in recalled milk produc... Read More
The international medical humanitarian organization Doctors Without Borders/Médecins Sans Frontières (MSF) has started a rabies intervention in the east of the Democratic Republic of Congo (DRC) after an alarming number of people were bitten by rabid dogs. With ten deaths already reported, the e... Read More
Mathematicians have found that by varying the timing of treatments, doctors may be able to increase the odds that a disease outbreak will die off suddenly.
Herding cats is a cakewalk compared with getting people to take flu vaccine shots in the last weeks of summer—work, school, limited pharm... Read More
With increasing attention toward generating cost-effective biochemical conversion methods for producing biofuels, it helps to follow the leaders who have perfected the process. The mere Reticulitermes flavipes, or eastern subterranean termite, a famous feaster of lignocellulosic plant materials ... Read More
“Implementation of infant rotavirus vaccination in 2006 has substantially reduced the burden of severe gastroenteritis among U.S. children younger than 5 years,” write Paul A. Gastanaduy, M.D., M.P.H., of the Centers for Disease Control and Prevention, Atlanta, and colleagues. “Whether indirect ... Read More
