When a new disease emerges, scientists and physicians hope something that’s already in the medicine cabinet can be used to treat it.
A new study suggests for the novel coronavirus, that may be the case.
Scientists from the U.S. National Institute of Allergy and Infectious Diseases are repo... Read More
As the death toll from China's bird flu outbreak rose to 22 with news of another victim in eastern Zhejiang Province, the World Health Organization warned the H7N9 virus was one of the most lethal that doctors and medical investigators had faced in recent years.

A modified strain of Salmonella could be used to efficiently deliver antigens, the key ingredients of vaccines, into human cells, a study suggests.
Salmonella bacteria use nanoscopic needles to inject their own proteins into host cells, enabling them to survive and replicate inside those cell... Read More
For the second time in a matter of weeks, a group of researchers reported a link between the food people eat and bacteria in the intestines that can increase the risk of heart attacks.
Two weeks ago, the investigators reported that carnitine, a compound found in red meat, can increase heart d... Read More
There’s been a recent surge in cases of the avian influenza A (H7N9) viral infection in China. As of this morning, there have been over a hundred reported cases and more than twenty deaths. The virus’ relatively sudden appearance in April, usually considered the end of flu season in the northern... Read More
Those of you with an interest in virology, or perhaps simply sensationalism, have probably seen the recent headlines proclaiming another laboratory-made killer influenza virus. From The Independent: ‘Appalling irresponsibility: Senior scientists attack Chinese researchers for creating new strain... Read More
Researchers use a protein-lipid complex found in human breast milk to increase the activity of otherwise-ineffective antibiotics against drug-resistant pathogens. A protein-lipid complex that naturally occurs in human breast milk can increase the sensitivity of methicillin-resistant Staphylococc... Read More
Thanks to a rare bacteria that grows only on rocks in the Swiss Alps, researchers at The University of Texas at Austin and the Pasteur Institute in France have been the first to identify how alcohol might affect key brain proteins.
It’s a major step on the road to eventually developing drugs ... Read More
Researchers have confirmed that the A H7N9 bird flu virus, which began in February 2013, was transmitted from chickens at a wet poultry market to humans, according to a new study published in the The Lancet.
Wet markets, which are common in Asian countries, are live animal markets.

Through the serendipity of science, researchers at the University of Pittsburgh have discovered a potential treatment for deadly, drug-resistant bacterial infections that uses the same approach that HIV uses to infect cells.
The National Institutes of Health-supported discovery will be descr... Read More
To infect its host, the respiratory pathogen Pseudomonas aeruginosa takes an ordinary protein usually involved in making other proteins and adds three small molecules to turn it into a key for gaining access to human cells. In a study to be published May 7 in mBio, the online open-access journal... Read More
It's easy to forget just how far medicine has progressed. While we may worry about the spread of infectious diseases like avian flu or meningitis today, those pathogens have nothing on fearsome pandemics in the distant past like the Plague of Justinian, which killed over 100 million people from ...

The microbial population in the air of the New York City subway system is nearly identical to that of ambient air on the city streets. This research, published ahead of print in the journal Applied and Environmental Microbiology, establishes an important baseline, should it become necessary to m... Read More
There’s no question that variation in size and shape has conferred selective advantages over the course of evolutionary time. One of the most obvious examples is the long neck and legs of the giraffe, which allow it to snatch foliage that is unreachable by vertically challenged competitors. The ... Read More
In its native state, according to the CDC, the H5N1 flu virus is highly contagious and is especially deadly to birds. Fortunately, few people have contracted this strain of flu as it's quite deadly in people as well. Luckily, there have been very few cases of transmission of the virus between pe... Read More
It's a chemical that's been in U.S. households for more than 40 years, from the body wash in your bathroom shower to the knives on your kitchen counter to the bedding in your baby's basinet.
But federal health regulators are just now deciding whether triclosan — the germ-killing ingredient fo... Read More
A new federal report blames a combination of problems for a mysterious and dramatic disappearance of U.S. honeybees since 2006.
