One way to avoid getting sick while traveling is to only eat fruit that you peel yourself, since plants can filter out bacteria and prevent it from traveling throughout their tissues. Well, why not apply this principle to filtering water directly? A team of scientists have done just that, testi... Read More
Tel Aviv University researchers have developed a computational model that explains how bacteria move in a swarm, which can be applied to man-made technologies, including computers, artificial intelligence, and robotics.
Ph.D. student Adi Shklarsh of TAU has discovered how bacteria collectivel... Read More
The genome of Medicago, a close relative of alfalfa and a long-established model for the study of legume biology, has been sequenced by an international team of scientists, capturing around 94 per cent of its genes.
The research gives new insights into the evolution of the Papilionoid subfami... Read More
Bacterial cells are fundamentally different to the cells of multicellular animals such as humans. They are far smaller, with less internal organisation and no nucleus (they have DNA but it is not packaged safely within a membrane). Because of this bacteria are almost exclusively single-celled or... Read More
Although scientists have known for centuries that many bacteria produce hydrogen sulfide (H2S) it was thought to be simply a toxic by-product of cellular activity. Now, researchers at NYU School of Medicine have discovered H2S in fact plays a major role in protecting bacteria from the effects of... Read More
Whooping cough is a respiratory disease caused by Bordetella pertussis, which induces mucosal IgA antibodies that appear to be relevant in protection. Serum IgA responses are measured after pertussis infection and might provide an additional role in pertussis diagnostics. However, the possible i... Read More
Responding to experiments in the Netherlands and the United States in which scientists created a highly transmissible form of the potentially deadly H5N1 bird flu virus, the National Science Advisory Board for Biosecurity urged scientific journals not to publish details of the work out of fear t...

Think of the weirdest creatures you’ve even seen in a sci-fi film. Now think of this: there are far stranger, albeit smaller, critters living in your own home. And Rob Dunn at North Carolina State University wants you to go on safari to find them.
Research has been done on the diversity of b... Read More
The largest U.S. outbreak of measles to occur in 15 years -- affecting 214 children so far -- is likely driven by travelers returning from abroad and by too many unvaccinated U.S. children, according to new research.
The finding could highlight the dangers of a trend among some U.S. parents t... Read More
It's not unusual for a patient to change doctors. Doctors retire, families move, insurance changes.
And sometimes, patients get fired.
"Discharging parents from a practice is never easy," says Thomas Tryon, a pediatrician at Children's Mercy Hospitals and Clinics in Kansas City, Mo. "I nev... Read More
New research suggests a pattern of outpatient antibiotic overuse in parts of the United States - particularly in the Southeast - a problem that could accelerate the rate at which these powerful drugs are rendered useless, according to Extending the Cure, a project of the Center for Disease Dynam...

Preventing pathogenic bacteria from sensing nutrient starvation may present a new therapeutic approach to increasing antibiotic efficacy and preventing drug resistance, researchers claim. A team led by McGill University investigators has found that blocking an active mechanism used by bacteria t... Read More
University of California, Berkeley, scientists have shown that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial - able to kill bacteria - for as long as a week after treatment.
Devices able to produce such plasmas are cheap, whi... Read More

Infectious disease experts support 'Get Smart About Antibiotics Week,' Nov. 14-20
With antibiotic-resistant infections increasingly common, and a dangerous lack of new infection fighters in the drug development pipeline, it's more important than ever to use existing antibiotics appropriately.... Read More
Anyone who has taken high school biology has likely come into contact with a ciliate. The much-studied paramecium is one of 7,000 species of ciliates, a vast group of microorganisms that share a common morphology: single-celled blobs covered in tiny hairs, or cilia. These cilia — Greek for “eyel... Read More
What do monocytes, lymphocytes, and neutrophils all have in common? Well, yes, they are all leucocytes and part of our immune system, but what else? They all can be prompted to migrate to the site of infection by a specific class of cytokines known as chemotactic cytokines, or chemokines for sho... Read More
The superbug MRSA (methicillin-resistant Staphylococcus aureus) has provoked fear in doctors and patients alike because it is endowed with genetic characteristics that make it impervious to many antibiotics, and it can be deadly to boot. Less well known, however, is another class of bacteria tha... Read More
A new University of Minnesota study reveals that the release of treated municipal wastewater – even wastewater treated by the highest-quality treatment technology – can have a significant effect on the quantities of antibiotic-resistant bacteria, often referred to as "superbacteria," in surface ...

In 1952, two years before his untimely death at the age of 41, the mathematician Alan Turing wrote an influential paper entitled "The Chemical Basis of Morphogenesis." The paper tackled the problem of how limbs and other structural patterns arise in plants and animals that begin life as undiffer... Read More
