It’s not hard to see that men are more likely to engage in risky behaviors than women, or that crime rates are many times higher among men, but this tendency to break the rules also extends to male scientists, according to a study to be published on January 22 in mBio®, the online open-access jo...

Poliovirus recently made the cover of Time magazine. Prompted by a reader question, I searched the Time archive to find out if there have been other virology-themed covers. I found fifteen in all, depicting poliovirus (3), herpesvirus (1), HIV/AIDS (4), influenza (5), and SARS coronavirus (2) (I... Read More
The mosquito that spreads the dengue virus is a homebody that infects visiting friends and relatives.
The Aedes aegypti mosquitoes that spread dengue fever tap into the domestic networks of humans, along with their bloodstreams, finds a study recently published in the Proceedings of the Natio... Read More
Viruses closely related to the new coronavirus that emerged last year in the Middle East have been discovered in specimens from a number of species of bats found widely throughout Europe and beyond, a new study shows.
The work suggests bats common to Europe, Russia, parts of Asia and Africa a... Read More
No one wants a hacking cough for days or weeks on end. But research shows that it generally takes about 18 days to get over a standard cough-based illness. Most of us grow impatient after a week or so and head to the doctor to get a prescription. The problem with that recourse, however, is that ... Read More
It’s always fascinating to me to see how seriously other parts of the world take the issue of antibiotic use in agriculture, given the long struggle in the United States to get the Food and Drug Administration to act and to get legislation through Congress. The European Parliament has voted down... Read More
A new technique designed to make current antibiotics more effective works by disabling select genes in bacteria.
Described in the journal Nature Biotechnology, the technique systematically identifies genes within E. coli bacteria that inhibit the production of molecules called reactive oxygen... Read More
Doctors don't clearly understand why some babies cry excessively and others don't, but a new study suggests abnormal gut bacteria could play a role.
The research identified a distinct bacterial "signature" in the guts of infants with colic, a term that describes babies who cry for more than ... Read More
Microorganisms may get a bad rap in a setting like a hospital, but in the world of research, they’re offering fascinating new insights into human health and disease.
One group of researchers, for example, has linked microbial changes in the gut to the dose-limiting gastrointestinal side effec... Read More
Last summer, we learned about fake poop made from soybeans that The Bill & Melinda Gates Foundation used to test high-tech commodes at their toilet fair.
Now, we've come across another type of artificial poop, and it's being created to help people with really bad cases of diarrhea.
This sy... Read More
In the search for alternatives to conventional antibiotics, researchers have identified an enzyme that kills the bacteria that causes strep throat.
The enzyme, PlyC, operates by locking onto the surface of a bacteria cell and chewing a hole in the cell wall large enough for the bacteria’s inn... Read More
Infectious bacteria have for the first time been caught performing "biological alchemy" to transform parts of a host body into those more suited to their purposes, by a team in Edinburgh.
The study, in the journal Cell, showed leprosy-causing bacteria turning nerves into stem cells and muscle... Read More
Why are women more prone to autoimmune diseases like lupus, multiple sclerosis and rheumatoid arthritis? A new study in mice points to a possible contributor: different types of bacteria that populate our guts.
It goes like this: Different mixes of bacteria reside in the innards of male and f... Read More
The mosquitoes that spread dengue fever tap into the domestic networks of humans, along with their bloodstreams, finds a study recently published in the Proceedings of the National Academy of Sciences (PNAS).
Like the housefly, the Aedes aegypti mosquito that spreads the dengue vir... Read More
A FORM of gene therapy developed by researchers at the Queensland Institute of Medical Research may provide hope to sufferers of HIV, preventing the virus from crippling the immune system by manipulating its genetic structure and turning HIV into a weapon against itself.
Dr David Harrich has ... Read More
Natural sensory system such as bacteria engineered to detect pollution and placed in a self-contained portable box could be the most effective way to track pollutants. Such devices are being developed as part of BIOMONAR, an EU-funded project which follows on from its predecessors, ECODIS and TO... Read More
“I’m the poet who does the impossible thing. I am the poet who aspires to have the biggest imagination in the room,” Christian Bök says bluntly. Yet his grandiose inventiveness has been focused on the most minuscule attempt at verse. After 11 years of working on what he’s dubbed “The Xenotext,” ... Read More
Anyone still laboring under the mistaken assumption that genes are the most important factor in determining destiny should take a look at research that is being reported in this week’s Science about a particular strain of mice that have a genetic predisposition to develop type 1 diabetes. It tur... Read More
A discovery about the way in which bugs spread throughout the body could help to develop stem cell treatments.
Researchers at the University of Edinburgh have found that bacteria are able to change the make-up of supporting cells within the nerve system, called Schwann cells, so that they tak... Read More
