Nearly half of consumers ignore use-by-dates on food

NEARLY half of consumers ignore use-by dates on food with experts warning they are putting their health at risk, a report has revealed.

Dr Wayne Anderson, food science and standards director, said food may be badly contaminated even if it appeared good enough to eat.

"We would caution peop... Read More

Hospitals 'need friendly bacteria'

Lessons learned from Florence Nightingale could prevent the spread of harmful bugs by allowing "friendly" bacteria into hospitals, an expert has claimed.
Sterile conditions in wards and operating theatres may be doing more harm than good by wiping out organisms that keep dangerous microbes at b... Read More

Antibiotics with a side of steak

We’re in a sad and weird place in biomedical science. In the 1940’s we got penicillin, in the following 30 years another 13 different classes of antibiotic were introduced. Since 1970 the number of new classes has dropped to a worrying 2. Since then we have found new ways to arrange the deckcha... Read More

FDA Gives Nod to New Leukemia Treatment‎

The FDA has approved a new compound for the treatment of acute lymphoblastic leukemia (ALL) patients who are allergic to asparaginase derived from Escherichia coli.

The agency gave the okay to asparaginase Erwinia chrysanthemi (Erwinaze) as a replacement for E. coli-derived asparaginase or pe... Read More

Raw Oysters Spike U.S. Rise in Bacterial Infections

Raw oysters, so good with hot sauce, increasingly can carry something even more unsettling to the stomach: A bacteria linked to vomiting, diarrhea and pain.

Infections with vibrio, a saltwater-based bacteria that can pool in shellfish, jumped 75 percent last year from 2006-2008, the U.S. Cent... Read More

Bacteria swarms could inspire new generation of smart robots

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

Genome Sequence Sheds New Light On How Plants Evolved Nitrogen-Fixing Symbioses

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

Bacteria with bodies – multicellular prokaryotes

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

Targeting Bacterial Gas Defenses Allow for Increased Efficacy of Numerous Antibiotics

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

Serum IgA Responses against Pertussis Proteins in Infected and Dutch wP or aP Vaccinated Children: An Additional Role in Pertussis Diagnostics

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

A Public Policy Expert Looks at the Bird Flu Threat

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...

Unvaccinated behind largest U.S. measles outbreak in years

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

Project Seeks Your Tiny Squatters

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

Refuse vaccines and risk dismissal by doctor

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

First-Of-Its-Kind 'Drug Resistance Index' For Superbugs Reveals Worrying Pattern Of Antibiotic Use In The Southeastern United States

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...

Blinding Bacteria to Nutrient Deficiency Boosts Sensitivity to Antibiotics

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

Sterilizing With Ionized Plasmas Kills Microbes For A Week

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

Small Things Considered: Virus Hacks Intercellular Communications Network

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
