Scouring the genomes and body-wide microbial communities of 93 people, researchers have discovered a link between the composition of the microbiome and genetic variation in innate immunity, phagocyte function, and other immune pathways. The research was presented by University of Minnesota popul... Read More
A combination of two well-known antiviral drugs protects monkeys against MERS and could potentially be used to save humans from the lethal disease, scientists said on Sunday.
Researchers at the National Institute of Allergy and Infectious Diseases gave the drugs, ribavirin and interferon, to ... Read More
Clumps of proteins twisted into aberrant shapes cause the prion diseases that have perplexed biologists for decades. The surprises just keep coming with a new report that the simple clusters of proteins responsible for Mad Cow and other prions diseases may, without help from DNA or RNA, be capab... Read More
Mealybugs only eat plant sap, but sap doesn't contain all the essential amino acids the insects need to survive. Luckily, the bugs have a symbiotic relationship with two species of bacteria -- one living inside the other in a situation unique to known biology -- to manufacture the nutrients sap ... Read More
Imagine swimming to the bottom of the sea, the water growing impossibly deep and dark the farther you travel. At these depths, beyond the reach of the sun, live strange new sources of light. Fish, jellyfish, and even bacteria light up these midnight waters.
According to new research in PLOS O... Read More
A new study shows that common mutant forms of the deadly JC polyomavirus are not responsible for the pathogen’s main attack, which causes a brain-damaging disease in immunocompromised patients called progressive multifocal leukoencephalopathy. But that finding raises the ominous question of what... Read More
Vaccines, including those used in protecting against influenza, do not put a person at increased risk of Guillain-Barré syndrome despite wide-spread concerns, according to a Kaiser Permanente study published in the journal Clinical Infectious Disease.
The retrospective study spanned 13 years ... Read More
In 2008, François-Henri Boissel was leading a charmed life. He was a young, successful investment banker working in Tokyo, Japan. And then the market crashed.
He thought of sticking it out, waiting until things improved, but then he remembered a conversation he’d had with his father, Jean-Pie... Read More
Hollywood has amplified the idea of a zombie apocalypse for a long time, and the stories have grown increasingly popular in pop culture, particularly due to TV shows like ‘The Walking Dead‘ and movies like ‘World War Z.’
However, when you take science fiction out of the equation and add real-... Read More
Why are these scientists in hazmat suits smiling? They're standing in a field that they are about to spread with raw manure – four different kinds of raw manure, to be exact.
Michele Jay-Russell, a University of California, Davis food safety scientist, posted the above picture on Twitter last... Read More
Each year, more than two million people in the United States develop antibiotic-resistant infections, and at least 23,000 of them die as a result, says the first-ever national snapshot of the issue. That toll only rises when other conditions exacerbated by these infections are included in the co... Read More
The toxoplasma parasite can be deadly, causing spontaneous abortion in pregnant women or killing immune-compromised patients, but it has even stranger effects in mice.
Infected mice lose their fear of cats, which is good for both cats and the parasite, because the cat gets an easy meal and th... Read More
A pair of commentaries to appear in an upcoming issue of the journal Antimicrobial Agents and Chemotherapy highlight a debate within the public health community surrounding Centers for Disease Control and Prevention (CDC) recommendations for treatment of exposed individuals during last year’s fu...

McMaster University researchers are about to launch Canada’s first tuberculosis (TB) vaccine clinical trial with a vaccine totally designed, manufactured and tested within McMaster.
"The exciting thing for McMaster is that this is translational research that has gone from the basic science wh... Read More
- The laboratory of Dr. Abrescia has described for the first time how the virus PRD1 uses lipids and proteins that are part of its structure to generate a nanotube used to translocate its genome and to penetrate and infect cells.
- The finding could boost new strategies to fight against bact... Read More
A tag team of two bacteria, one of them genetically modified, has a good chance to reduce or even eliminate the deadly disease African trypanosomiasis, or sleeping sickness, researchers at Oregon State University conclude in a recent mathematical modeling study.
African trypanosomiasis, cause... Read More
What is wrong with this paragraph from today’s New York Times that describes the origin of the Middle East Respiratory Syndrome (MERS) coronavirus:
Health officials confirmed Wednesday that bats in Saudi Arabia were the source of the mysterious virus that has sickened 96 people in the Middle ... Read More
Researchers have discovered why the parasite that causes the deadliest form of malaria only infects humans.
The team recently showed that the interaction between a parasite protein called RH5 and a receptor called basigin was essentially required for the invasion of red blood cells by the par... Read More
In the past year a group of synthetic proteins called CRISPR-Cas RNA-guided nucleases (RGNs) have generated great excitement in the scientific community as gene-editing tools. Exploiting a method that some bacteria use to combat viruses and other pathogens, CRISPR-Cas RGNs can cut through DNA st... Read More
We have the dubious privilege of observing a new disease in the midst of being born. The disease could go on to spread around the world, stall out as a minor, local blight, or disappear altogether. Scientists have been observing its emergence for a year now, and while they know more than they di... Read More
