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
Triclosan – a synthetic antibacterial widely used in personal care products – is fueling the development of resistant bacteria in streams and rivers. So reports a new paper in the journal Environmental Science and Technology, which is the first to document triclosan resistance in a natural envir... Read More

Middle East Respiratory Syndrome (MERS) is viral respiratory illness first reported in Saudi Arabia in 2012. It is caused by a coronavirus called MERS-CoV. Most people w... Read More
Doses of a human gut microbe helped to reverse behavioural problems in mice with autism-like symptoms, researchers report today in Cell. The treatment also reduced gastrointestinal problems in the animals that were similar to those that often accompany autism in humans.
The work builds on pre... Read More
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
Rhinovirus C is believed to be responsible for up to half of all childhood colds, and is a serious complicating factor for respiratory conditions such as asthma. Together with rhinoviruses A and B, the recently discovered virus is responsible for millions of illnesses yearly at an estimated annu... Read More
Suppose that one day you have the misfortune to receive a strong dose of radiation in preparation for a medical procedure, say a bone marrow transplant. To your surprise, the physician prescribes that you eat a hefty serving of dark-colored mushrooms about an hour beforehand. Lest you think this... Read More
(upwave.com) -- Even if you're one of the many people who believe that exposing yourself to day-to-day germs is healthy for your immune system, it's still wise to take steps to protect yourself from the most infectious germs in your home. "Bugs like Escherichia coli (E.coli), salmonella and camp... Read More
People living near pig farms or agricultural fields fertilized with pig manure are more likely to become infected with methicillin-resistant Staphylococcus aureus (MRSA) bacteria, according to a paper published today in JAMA Internal Medicine1.
Previous research has found that livestock worke... Read More
Genomic analysis of transplant patients finds an opportunistic microorganism whose elevated presence could be used an indicator in treatment.
More than 260,000 Americans are alive today thanks to transplant operations that have replaced their failing kidneys, hearts, lungs or livers with hea... Read More
We live in a world run by microbes, the vast majority of which we have yet to identify or name. We can only refer to them collectively as the microbial dark matter (MDM). However you define a prokaryotic species, and however you tally them once identified, there is a huge gap between the 12,000 ... Read More
A new transcriptomics-based model accurately predicts how much isoprene the bacterium Bacillus subtilis will produce when stressed or nourished. This model marks a step toward understanding how changes in the bacteria's environment affect gene expression and, in turn, isoprene production. Isopre... Read More
Low birth weight infants are host to numerous microorganisms immediately after birth, and the microbiomes of their mouths and gut start out very similar but differentiate significantly by day 15 according to a study in mBio this week. Researchers from Stanford University and the University of Pi... Read More
Researchers at Lund University in Sweden have for the first time managed to measure the internal pressure that enables the herpes virus to infect cells in the human body. The discovery paves the way for the development of new medicines to combat viral infections. The results indicate good chance... Read More
Food transit through the small intestine affects the body's absorption of nutrients and, consequently, our health. The discovery that food transit time is regulated by a hormone indicates new ways to increase the intestinal absorption of nutrients, and thus potentially treat malnutrition.
One... Read More
New microfluidic technique quickly distinguishes bacteria within the same strain; could improve monitoring of cystic fibrosis and other diseases. There are good bacteria and there are bad bacteria — and sometimes both coexist within the same species.
Take, for instance, Pseudomonas aeruginos... Read More
Twitter clips human thoughts to a mere 140 characters. Animals’ scent posts may be equally as short, relatively speaking, yet they convey an encyclopedia of information about the animals that left them.
In the current issue of the Proceedings of the National Academy of Sciences, a Michigan St... Read More
Natural selection favours those with a greater capacity to generate genetic variation.
Some gamblers succeed by spiriting cards up their sleeves, giving them a wider range of hands to play. So do some bacteria, whose great capacity for genetic variability helps them evolve and adapt to rapidl... Read More
Researchers in Umeå and Uppsala have found that residues of the influenza drug Tamiflu in our environment can make the influenza virus in birds resistant. This can have serious consequences in the event of an influenza pandemic. With more than 14 million SEK from the Swedish Research Councils Fo... Read More
An experimental vaccine against human cytomegalovirus (CMV) infection, which endangers the developing fetus, organ transplant recipients, patients with HIV and others who have a weakened immune system, proved safe and more effective than previous vaccines developed to prevent infection by the ub...
