The most detailed analysis to date of the spread of the H1N1 2009 pandemic influenza virus, known informally as ‘swine flu’, has found that short-range travel was likely the primary driver for the 2009 pandemic in the United States, in contrast with popularly accepted views on the way diseases s...

Mothers give a newborn baby a gift of germs -— germs that help to kick-start the infant’s immune system. But antibiotics, used to fight bacterial infection, may paradoxically interrupt a newborn’s own immune responses. A new animal study by neonatology researchers at The Children's Hospital of P...

Researchers at Bigelow Laboratory for Ocean Sciences dug into the last 70 years of peer-reviewed publications about protozoan parasites that infest bivalve mollusks and found that when an organism can be cultured in the laboratory, more papers and greater understanding result. Senior Research S... Read More
If you pull up a soybean or bean plant and shake off the dirt, you might see odd swellings or bumps, like rheumatic finger joints, on its roots. Inside the cool, soil-covered bumps are bacteria that are making nitrogen with the help of an enzyme, something chemical factories can do only with the... Read More
An experimental vaccine against human cytomegalovirus (CMV) infection, which endangers the developing fetus, organ transplant recipients, patients with HIV and others who have a weakened immune system, proved safe and more effective than previous vaccines developed to prevent infection by the ub...

Whooping cough was once one of the leading killers of babies around the world. Now that it's largely controlled with a vaccine, scientists have had a chance to figure out how the disease came into being in the first place. That story is told in a study published online this week in the journal m... Read More
The 'post-antibiotic' era is near, according to a report released today by the World Health Organization (WHO). The decreasing effectiveness of antibiotics and other antimicrobial agents is a global problem, and a surveillance system should be established to monitor it, the group says. There is ... Read More
Using an experimental technique new to the dengue field, the labs of Ralph Baric, PhD, and Aravinda de Silva, PhD, showed that a molecular hinge where two regions of a protein connect is where natural human antibodies attach to dengue 3 to disable it. The finding, published in the Proceedings of... Read More
Ever since a highway construction crew in Chile uncovered a fossil graveyard of some 40 prehistoric whales in 2010, with skeletons dating back more than five million years, scientists have wondered why so many giant animals died in one place. This week, a team of them proposed an answer: The hug... Read More
Methicillin-resistant S. aureus (MRSA) constitutes approximately 50% of clinical S. aureus isolates and is most commonly the result of production of a mutated pencillin-binding protein, PBP2a, which is able to carry out essential cell wall synthesis functions while maintaining a low-affinity for...

Banana lovers take note: The world's supply of the fruit is under attack from a fungus strain that could wipe out the popular variety that Americans eat. "It's a very serious situation," said Randy Ploetz, a professor of plant pathology at the University of Florida who in 1989 originally discove... Read More
Partial isolate of an unknown organism on trypticase soy agar exhibiting spreading and mounding in an irregular-rhizoid form with lobate margins. The colony exhibited an opaque yellow-orange pigment with a mucoid surface. This sample was obtained from a floor swab and incubated at 37°C. Read More
Making hydrogen easily and cheaply is a dream goal for clean, sustainable energy. Bacteria have been doing exactly that for billions of years, and now chemists at the University of California, Davis, and Stanford University are revealing how they do it, and perhaps opening ways to imitate them.

The instructions encoded into DNA are thought to follow a universal set of rules across all domains of life. But researchers report in the May 23 issue of Science that organisms routinely break these rules.
The finding has implications for the design of synthetic life: by designing organisms ... Read More
New research reveals the complex dynamic between gut bacteria and the immune system that keeps proteins from flagellin—bacterial tails—under control.
In healthy individuals, the only thing that separates the lining of the human gut from the some 100 trillion bacterial cells in the gastrointes... Read More
A graduate student came to my office recently to say that she was increasingly bothered by anxiety and the ‘terror’ of having to speak at laboratory meetings. She had also learned a month ago that she was expected to lecture to a class organized by her mentor. The thought of having to lecture to... Read More
Researchers have identified the evolutionary origins of human herpes simplex virus (HSV) -1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans -- H...
