Programmed Cell Death Activates Latent Herpesviruses

Researchers have found that apoptosis, a natural process of programmed cell death, can reactivate latent herpesviruses in the dying cell. The results of their research, which could have broad clinical significance since many cancer chemotherapies cause apoptosis, was published ahead of print in ... Read More

Human antibodies that neutralize respiratory droplet transmissible H5N1 influenza viruses

There have been several outbreaks of highly pathogenic H5N1 avian influenza viruses affecting humans over the past decade, the causes of which have been limited to direct human contact with infected birds. Recent publications suggest that a very small number of coding mutations in the viral HA g... Read More

PRRS Virus Evolution Slows

Porcine reproductive and respiratory syndrome (PRRS) virus remains a very important disease of swine in the United States. At the University of Minnesota Veterinary Diagnostic Laboratory, hundreds of samples are routinely tested for this virus by polymerase chain reaction (PCR) every month. This... Read More

Multiple Mutations Often Needed to Make TB Bacteria Drug-Resistant

Tuberculosis (TB) drug resistance is not an all-or-none phenomenon, according to new research from Rutgers, The State University of New Jersey. Rather, TB-causing bacteria often accumulate mutations in a step-wise fashion, with the initial mutation having minimal impact but poising the bug to la... Read More

Chobani Pulls 'Fizzy,' 'Swelling' Yogurt Off Shelves

TWiM 63 Letters

Hugh writes:


Hi Vincent,


I really enjoyed hearing about Carl Woese in TWiM #50. You mentioned the controversy surrounding of Woese's 1977 discovery of Archea as a third domain of life, as it contradicted entrenched scientific beliefs. Although Archea soon foun... Read More

Victory in the Battle against Brucella: From bench to battlefield

After six years of focused research, Rice-Ficht, director of the Center for Microencapsulation and Drug Delivery at the Texas A&M Health Science Center (TAMHSC), her co-principal investigators and team are nearing completion on the first human Brucella vaccine. Brucella bacteria cause brucellosi... Read More

Your Gut Bacteria May Predict Your Obesity Risk

Bacteria in people's digestive systems -- gut germs -- seem to affect whether they become overweight or obese, and new research sheds more light on why that might be.

The findings, from an international team of scientists, also suggest that a diet heavy in fiber could change the makeup of the... Read More

Amazon Virus Moves Quicker than Dengue

An Amazon virus that causes symptoms similar to those of dengue had part of its action mechanism unraveled by researchers from UFRJ (Federal University of Rio de Janeiro).

Mammals harbor ~320,000 viruses. Could $6.3 billion discover them all?

What will the next big zoonotic virus be? Most emerging infectious diseases are zoonoses, and many, if not most, of them are caused by viruses, but right now we have little idea what viruses are out there in livestock and wildlife, let alone which one might be next in line to cause a human pande...

Japan producing vaccine against H7N9 bird flu

The Ministry of Health, Labor and Welfare announced on Monday that it will pursue the production of vaccine against the H7N9 avian flu virus that is still spreading across China. The ministry aims to develop the vaccine as soon as possible before the virus mutates and imposes further risk to hum... Read More

Some flu vaccines promise a little more protection

Flu vaccination is no longer merely a choice between a jab in the arm or a squirt in the nose. This fall, some brands promise a little extra protection.

For the first time, certain vaccines will guard against four strains of flu rather than the usual three. Called quadrivalent vaccines, these... Read More

Cracking bacteria's secrets may lead to new treatments

Scientists have found another chink in bacteria's armour, mapping for the first time the structure of a protein that plays an important role helping infection gain a foothold in the body.

Published today in Nature a group of international scientists from Monash University, the National Instit... Read More

Mtb Craves Sweets

Tuberculosis is an ancient disease that still affects millions of people, largely in developing countries. A startling statistic valued by fundraisers for tuberculosis research is that this devastating disease claims three lives every minute worldwide. Since a major factor underlying this import...

Gut Lecture

Over the many years that I taught microbiology to medical students, perhaps my least favorite lecture was the one on the “normal flora,” what we now call the microbiome. What used to make me grumpy was that I could talk only in vague generalities, rambling about the intestinal flora being an imm... Read More

Bacteria Supplemented Their Diet to Clean Up After Deep Water Horizon Oil

Bacteria living in the Gulf of Mexico beaches were able to 'eat up' the contamination from the Deep Water Horizon oil spill by supplementing their diet with nitrogen, delegates at the Goldschmidt conference will be told today, Friday 30th August.

Professor Joel Kostka will tell geochemists ga... Read More

Infrared light used to outwit sneaky, deadly bacteria

Researchers have devised a way to turn the tables on a sneaky strain of bacteria that can cause life-threatening diseases, based on a technique using infrared light.

Scientists at the University of Veterinary Medicine, Vienna said the technique lets them differentiate strains that can cause ... Read More

Dueling Infections: Parasitic Worms Limit the Effects of Giardia, and Vice Versa

If the idea of hookworms makes you shudder, consider this: Those pesky intestinal parasites may actually help your body ward off other infections, and perhaps even prevent autoimmune and other diseases.

Studying members of the Tsimane, an indigenous population in the lowlands of Central Boliv... Read More
