Link identified between virus recognition, destruction in bacterial immune system

An immune system that helps bacteria combat viruses is yielding unlikely results such as the ability to edit genome sequences and potentially correct mutations that cause human disease.

University of Georgia researchers Michael and Rebecca Terns were among the first to begin to study the bact... Read More

Why some HPV infections go away and others become cancer

For people infected with the human papilloma virus (HPV), the likelihood of clearing the infection and avoiding HPV-related cancer may depend less on the body's disease-fighting arsenal than has been generally assumed. Read More

Teenager with stroke symptoms actually had Lyme disease

A Swiss teenager, recently returned home from a discotheque, came to the emergency department with classic sudden symptoms of stroke, only to be diagnosed with Lyme disease.

"Everything about her symptoms indicated stroke: speech deficits, poor comprehension and right-sided face and arm weak... Read More

Attention, All Scientists: Do Improv

Martha Furie stormed into the room and huffily sat down in a chair.

“Well, you know, I’ve been working really hard, studying Lyme disease,” she said, her voice tinged with disdain, to the woman sitting in the next chair. “It’s been a long process. It’s hard to talk about it.”

The other wom... Read More

Spherical nucleic acids set stage for new paradigm in drug development

A research team led by Northwestern University nanomedicine expert Chad A. Mirkin and Sergei Gryaznov of AuraSense Therapeutics is the first to show spherical nucleic acids (SNAs) can be used as potent drugs to effectively train the immune system to fight disease, by either boosting or dampening...

Ebola survivors offer clues to body's virus defences

The human body can mobilize a strong defense against Ebola virus, suggests a study of four people with the virus who were treated in the United States last year.

A team led by immunologist Rafi Ahmed of Emory University in Atlanta, Georgia, found that the people treated at Emory between Augus... Read More

The bioluminescent bacteria

Growth of the gram negative bacteria Vibrio fischeri expressing bioluminescence as a result of the symbiotic interaction with Euprymna scolopes. You can see the plate without shining and glowing in the dark. The Form is the mascot of the University of Puerto Rico at Rio Piedras campus. Read More

STOP SUPERBUGS BY TURNING UP THE HEAT

U. MINNESOTA (US) — One effective way to fight the spread of antibiotic-resistant bacteria, known as “superbugs,” may be to treat municipal wastewater solids at higher temperatures. Heating the solid waste to 130 degrees Fahrenheit (55 degrees Celsius) was particularly effective in eliminating ... Read More

Mental Health May Depend on Creatures in the Gut

The microbiome may yield a new class of psychobiotics for the treatment of anxiety, depression and other mood disorders.The ongoing exploration of the human microbiome promises to bring the link between the gut and the brain into clearer focus. Scientists are increasingly convinced that the vast... Read More

Common Parasite Could Manipulate Our Behavior

Look what the cat dragged in! The parasite Toxoplasma gondii, a common protozoan transmitted by cats, can effect mammalian brain cells in strange ways. In rodents, the parasite has been shown to inhibit fear and actually attract them to the smell of cat urine. Humans can be infected through c... Read More

New targets for rabies prevention and treatment

Researchers have identified genes that may be involved in determining whether an individual is sensitive or resistant to rabies virus infection. Read More

Protection Without a Vaccine

Last month, a team of scientists announced what could prove to be an enormous step forward in the fight against H.I.V.

Scientists at Scripps Research Institute said they had developed an artificial antibody that, once in the blood, grabbed hold of the virus and inactivated it. The molecule ca... Read More

Radical Vaccine Design Effective Against Herpes Viruses

Herpes simplex virus infections are an enormous global health problem and there is currently no viable vaccine. For nearly three decades, immunologists’ efforts to develop a herpes vaccine have centered on exploiting a single protein found on the virus’s outer surface that is known to elicit rob... Read More

Why China's Pollution Could Be Behind Our Cold, Snowy Winters

The other beta hemolytic streptococci are not sensitive to bacitracin. Isolated of Beatrice Rogolino M.Sc - photo Francesco d'Aleo... Read More

Chlorine use in sewage treatment could promote antibiotic resistance

Chlorine, a disinfectant commonly used in most wastewater treatment plants, may be failing to completely eliminate pharmaceuticals from wastes. As a result, trace levels of these substances get discharged from the plants to the nation's waterways. And now, scientists are reporting preliminary st... Read More
