Two separate research groups are reporting groundbreaking measurements of the fluid flow that surrounds freely swimming microorganisms. Experiments involving two common types of microbes reveal the ways that one creature's motion can affect its neighbors, which in turn can lead to collective mot... Read More
William C. Patrick III made enough germs to kill everyone on earth many times over. Then, after putting aside those living weapons, he worked for nearly four decades to build defenses against them, to protect the United States from biological attack.
A scientist, Dr. Patrick made germ weapons... Read More
Wouter Roos and Gijs Wuite, respectively FOM researcher and FOM workgroup leader at VU University Amsterdam, discuss recent developments in the area of 'physical virology' in the journal Nature Physics. This new and rapidly growing discipline studies viruses, which can be viewed as 'natural nano... Read More
There are many ways of fighting disease, but Brian Allan from Washington University has suggested a most unusual one – a spot of weeding. Allan’s research shows that getting rid of a plant called the Amur honeysuckle might be one of the best ways of controlling an emerging human disease called ... Read More
Urinary tract infections, pneumonia and other common ailments caused by germs that carry a new gene with the power to destroy antibiotics are intensifying fears of a fresh generation of so-called superbugs.
The gene, NDM-1, which is apparently widespread in parts of India, has been identifie... Read More
Like a household wire carries electrons from wall socket to appliance, bacteria can conduct electricity along tiny wire-like appendages, researchers report in the Oct. 11 Proceedings of the National Academy of Sciences.
A community of bacteria connected by these gangly nanowires could act as ... Read More
Last year, a team of Argonne scientists led by Lorraine LaFreniere injected iron microparticles underneath fields long-polluted with carbon tetrachloride near Centralia, Kansas. The researchers coated the microparticles with organic material, which served as bait for bacteria that created the co... Read More
Advocates for seeding regions of the ocean with iron to combat global warming should be interested in a new study published today in Geophysical Research Letters. A Canada-US team led by University of Victoria oceanographer Dr. Roberta Hamme describes how the 2008 eruption of the Kasatochi volca... Read More
Common frog (Rana temporaria) populations across the UK are suffering dramatic population crashes due to infection from the emerging disease Ranavirus, reveals research published in the Zoological Society of London's (ZSL) journal Animal Conservation.
Using data collected from the public by t... Read More
The bacterium Campylobacter jejuni is a major cause of food poisoning in humans. It is normally transmitted from contaminted chicken meat, as it is frequently found in the intestines of chickens, where it apparently does not result in any symptoms. Campylobacter jejuni is well adapted to life... Read More
Corn that's been genetically engineered to resist attacking borers produces a "halo effect" that provides huge benefits to other corn planted nearby, a new study finds. Since the borers that attack the genetically modified crops die, there are fewer of them to go after the non-modified version.

India has the highest number of child deaths, under the age of five. Nearly all were preventable, if basic hygiene practices were followed.
But since sanitation facilities are lacking in many parts of the country, scientists are looking at alternative ways to combat diseases in children - inc... Read More
China's Ministry of Health on Saturday issued guidelines urging full preparations at medical institutions nationwide for treating the multi-drug resistant NDM-1 bacteria.
According to the guidelines, it is likely that the bacteria is mainly transmitted through close contact, with key vulnerab... Read More
With antibiotic-resistant bacteria killing more Americans every year in U.S. hospitals than died during the decade-long Vietnam War, David M. Shlaes says it's time for federal regulators to rethink policies that have encouraged major companies to abandon antibacterials research.
And the 62-ye... Read More
Researchers Dr. Steven E. Schutzer of UMDNJ-New Jersey Medical School and Dr. Claire M. Fraser-Liggett of the Institute for Genome Sciences, University of Maryland, and their collaborators have made a major achievement toward better understanding Lyme disease, by determining the complete genetic...

Scientists have managed to alter the cell wall of Staphylococcus aureus bacteria to "trick" them into accepting small molecules and embedding them.
The development could lead to ways of combating staph infections that can cause pneumonia and a wide range of skin infections. A dangerous antibi... Read More
Swine flu no longer represents a major threat in the United States because so many people are immune to the virus that caused last season's pandemic, health officials said.
Of the 310 million people in the United States, 59 percent are believed to be immune to pandemic H1N1 flu, the researche... Read More
Yi-Cheng Su knows how much people enjoy eating a briny, cold, fresh raw oyster.
But as tasty as the cocktail sauce-doused treat can be, shellfish can carry bacteria that will wreak havoc upon your digestive tract — at least for a few days — and has even been known to be a killer.
So Su, an... Read More
Could an immune reaction to a virus cause autism? We still don’t know the answer to that question, but a new study shows that, in mice, infecting a pregnant mother with an artificial virus can spark a chain of events that leads to autism-like disorders in her offspring.
The study, just rel... Read More
Researchers at the Institute for Genomic Biology at the University of Illinois have developed a way to harness the prodigious quantities of both genomic and metabolic data being generated with high-throughput genomics and other techniques. They have developed an algorithm that automatically inte... Read More
