Single mutation gives virus new target

A mutation as minute as swapping just one amino acid can completely change the target that a virus will bind to on a victim cell — potentially shifting what kind of cell and eventually what kind of organism a virus could infect.

In a new study published online in the journal PLoS Pathogens, a... Read More

New Evidence for Role of Specific Virus Causing Type 1 Diabetes

Type 1 diabetes is a disease caused by the destruction of the insulin-producing cells in the pancreas. It is often diagnosed in childhood and requires life-long treatment with daily insulin injections. It is associated with an increased risk for long-term complications which decrease the quality...

Hitchhiking virus confirms saga of ancient human migration

A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome.

The virus under study, herpes simplex virus type 1 (HSV-1), usual... Read More

Antibiotics Can't Keep Up With 'Nightmare' Superbugs

We're used to relying on antibiotics to cure bacterial infections. But there are now strains of bacteria that are resistant to even the strongest antibiotics, and are causing deadly infections. According to the CDC, "more than 2 million people in the United States every year get infected with a ... Read More

In sub-Sahara, foot and mouth disease moves over short distances

You probably remember foot and mouth disease (FMD) from the 2001 outbreak in the UK that prompted the culling of over 10 million sheep and cattle, but the disease affects livestock all over the world. It's a particular problem in Africa, where wildlife that harbor the picornavirus that causes FM... Read More

Clay Can Kill Some Antibiotic-Resistant Bacteria (video)

Researchers have found that some clay can kill powerful bacteria like e-coli and even Methicillin-resistant Staphylococcus aureus, or MRSA, which can be resistant to many antibiotics. Read More

Research offers new insight in quest for single vaccine against multiple influenza strains

A study led by St. Jude Children’s Research Hospital scientists highlights a new approach for developing a universal influenza vaccine that could protect against multiple flu strains, including deadly pandemic strains. The research appears today in the advance online edition of the scientific jo... Read More

Flu Virus Wipes Out Immune System's First Responders to Establish Infection

Revealing influenza’s truly insidious nature, Whitehead Institute scientists have discovered that the virus is able to infect its host by first killing off the cells of the immune system that are actually best equipped to neutralize the virus.

Confronted with a harmful virus, the immune syste... Read More

Frontline Investigates the Rise of Deadly, Drug-Resistant Bacteria that Modern Antibiotics Can’t Stop - Press Release

FRONTLINE Presents
Hunting the Nightmare Bacteria
Tuesday, October 22, 2013, at 10 p.m. on PBS

Addie Rerecich was a happy 11-year-old girl who loved sports and talked a mile a minute. But when a mysterious pain in her hip landed her in the hospital in 2011, she began a downward spiral into ... Read More

‘Nightmare’ bacteria are real, and the U.S. needs to act fast

Last spring, Arjun Srinivasan, an associate director of the Centers for Disease Control and Prevention, delivered a presentation to state health officials with some alarming information. Before the year 2000, he said, it was rare to find cases of bacteria resistant to carbapenems, a class of pow... Read More

Why Scientists Are Trying Viruses To Beat Back Bacteria

Not all viruses are bad for us. Some of them might even help up us fight off bacterial infections someday.

Naturally occurring viruses called bacteriophages attack specific types of bacteria. So researchers at the University of Leicester decided to try and take advantage of phages' bacteria-d... Read More

Scientists Turn Dr. Frankenstein, Re-Write Bacteria’s Entire Genome

It may sound like science fiction, but researchers at Yale and Harvard have taken the first steps towards a Dr. Frankenstein-type reality, by fundamentally changing the genetic code of an organism.

The scientists were able to rewrite the genetic alphabet of the common bacteria E.coli, creatin... Read More

Much breast milk bought online is contaminated, analysis shows

Desperate for breast milk, some new mothers who can't nurse their babies are turning to online sources, typically strangers with ample supplies. But a new study finds that human milk bought and sold on the Internet may be contaminated — and dangerous.

Nearly 75 percent of breast milk bought t... Read More

The role of uncertainty in infectious disease modelling

The study found that many models provided only cursory reference to the uncertainties of the information and data, or the parameters used

Research by scientists at the University of Liverpool has found that greater consideration of the limitations and uncertainties in infectious disease model... Read More

A Bacterial Body Clock: Cryptic Periodic Reversals In Paenibacillus dendritiformis

As humans we live our lives in 24-hour increments—waking, eating, and sleeping at specific times dictated to us not solely by our discerning willpower, but also by the greater underlying persuasion of our circadian rhythm. Based on the earth’s rotation from day into night, we have internalized a... Read More
