Researchers have found that a commonly used anti-fungal treatment increases susceptibility to severe influenza infection in mice. This treatment deactivates an important protein that protects against viral infections such as influenza.
Amphotericin B is an important anti-fungal treatment for ... Read More
What happens when you use tiny electromagnetic coils to shift the position of light-scattering bacteria? In the hands of a couple of science-minded artists, you get an intriguing "Living Mirror."
I have a new favorite artist: bacteria. Imprinted onto cell phones, it can look like flowers, or ... Read More
Boston researchers are reporting the return of the HIV virus in two patients who had become virus-free after undergoing bone marrow transplants, dashing hopes of a possible cure that had generated widespread excitement.
The rebound of the virus shows its persistence, and that it can hide in p... Read More
Several African nations could strike a major blow against malaria by sacrificing the efficacy of some older drugs. Can they make it work?
It is September in southeastern Mali, and Louka Coulibaly is standing in the shade of a squat, concrete building, giving instructions to a dozen men and wo... Read More
HIV has reappeared in the blood of two Boston patients who scientists had hoped had been cured of their infections.
This disappointing development, reported by The Boston Globe's Kay Lazar, is yet another cautionary tale of how researchers can never afford to underestimate the human immunodef... Read More
Some time ago, we asked this Talmudic Question: Can you think of a place on Earth where there is free water but no microbes? (A sterile flask of nutrient broth in a lab, the insides of the body, or an IV bag in a hospital don't count.) Someone answered that perhaps deep in Antarctica there would... Read More
From cow burps to tree hiccups and melting permafrost, the potent greenhouse gas methane is produced in myriad ways. Now we can add another one to the list: electricity-generating microbes. The finding could one day allow us to control the generation of methane.
Methanosaeta microbes are one ... Read More
Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and min... Read More
Bacteria may lack a true immune system, but this does not leave them defenseless against bacteriophage viruses and other pathogens. A system of genomic sequence elements called clustered regularly interspaced short palindromic repeats (CRISPR) and various CRISPR-associated proteins (Cas) help to... Read More
From a bacteria’s perspective the environment is one big DNA waste yard. Researchers have now shown that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome. This discovery may have major consequences – both in connection with resi... Read More
Bacterial proteins could alter precipitation patterns and climate-change models.
Proteins can help grow teeth and bones in the body, crops in the ground, and even ice in the atmosphere. Some proteins have an uncanny knack for kick starting ice formation at unusual temperatures, and they have ... Read More
Doses of a human gut microbe helped to reverse behavioral 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 prev... Read More
Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.
The finding, by infectious disease researchers at the University of Adelaide and The University of Queensland, opens the way for further work to des... 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
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
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
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.
