With the help of a tiny worm, Cornelia Bargmann is unpicking the neural circuits that drive eating, socializing and sex. Male sexual dysfunction is never pretty, even in nematodes. In normal roundworm courtship, a slender male will sidle up to a plump hermaphrodite, make contact, and then initia... Read More
Scientists are targeting disease-causing bacteria present on cows’ skin as an attempt to prevent them from contaminating beef meat, and from posing a threat to consumers’ health.
If you can't kill them, trap them. Such is the fate that scientists are reserving to pathogenic bacteria, such as ... Read More
In the mid-1990s, people in the United States and Canada began to notice something grotesque. The frogs in their local ponds were sprouting extra legs.
As news of the deformed frogs spread, the Minnesota state government set up a hot line for sightings, and soon they got hundreds of calls fro... Read More
Researchers in Australia have provided the final piece of a puzzle to develop a new anti-malarial drug, which targets the parasite that causes the disease and kills it with a salt overdose.
The drug, the first discovery in the fight against malaria in two decades, holds out fresh hope for con... Read More
A suffocating fungus that threatens amphibians around the world has skipped over the diverse frog population in West Africa.
Amphibians are one of the most threatened animal groups in the world; almost one third of all species are under acute threat. One of the main reasons for their decline ... Read More
A team of scientists and surgeons from Newcastle are developing a new nasal spray from a marine microbe to help clear chronic sinusitis. They are using an enzyme isolated from a marine bacterium Bacillus licheniformis found on the surface of seaweed which the scientists at Newcastle University w... Read More
A team of molecular biology students at the University of Surrey has created a series of 'artworks' by imprinting mobile phones onto a layer of bacteriological growth media.
Students in the undergraduate Practical and Biomedical Bacteriology class run by Simon Park were encouraged to imprint ... Read More
The new coronavirus that has emerged in the Middle East is well-adapted to infecting humans but could potentially be treated with immunotherapy, according to a study in mBio this week. The study indicates that the virus HCoV-EMC can penetrate the bronchial epithelium and evade the innate immune ... Read More
Harvard University is home to some of the world’s finest virologists. But apparently they do not communicate with the writers at Harvard Magazine, where a botched story on the avian H5N1 influenza virus has just been published. Read More
The UK's national synchrotron facility, Diamond Light Source, is now the first and only place in Europe where pathogens requiring Containment Level 3 -- including serious viruses such as those responsible for AIDS, Hepatitis and some types of flu -- can be analysed at atomic and molecular level ...

Performing sensitive biological experiments is always a delicate affair. Few researchers, however, contend with the challenges faced by Cheryl Nickerson, whose working laboratory aboard the International Space Station (ISS) is located hundreds of miles above the Earth, traveling at some 17,000 m...

Fungi living beneath the seafloor are widespread in ocean environments around the world, according to a new paper by scientists at the University of Delaware and Woods Hole Oceanographic Institution.
“They’re ubiquitous,” said co-author Jennifer Biddle, assistant professor of marine bioscien... Read More
High on the list of the exciting manners bacteria communicate with one another is quorum sensing (QS), a population-dependent gene regulation system that operates within a wide range of species. The general scheme of QS is as follows: at high population densities, signal molecules called autoind... Read More
DNA preserved in calcified bacteria on the teeth of ancient human skeletons has shed light on the health consequences of the evolving diet and behaviour from the Stone Age to the modern day.
The ancient genetic record reveals the negative changes in oral bacteria brought about by the dietary ... Read More
For every one of our own cells, our bodies play host to 10 other microbial cells: bacteria, fungus, viruses and other microscopic creatures that scientists are still working to discover and understand. In other words, we're outnumbered by these 100 trillion or so microbes -- many of them strange... Read More
Replacing missing gut bacteria in a mouse model of autism reverses adverse social behaviours and gut disorders associated with the condition.
Last year, Sarkis Mazmanian and Paul Patterson at the California Institute of Technology in Pasadena found that infecting pregnant mice with molecules ... Read More
Bacteria from a healthy person can be transplanted to an ill person to help them recuperate. Visiting Jamaican-born Prof Karen E Nelson, president J Craig Venter Institute, explained this was one of the strides being made in genomics, which is the study of the collective genetic material in an o...

BIRD FLU (H5N1) has receded from international headlines for the moment, as few human cases of the deadly virus have been reported this year. But when Dutch researchers recently created an even more deadly strain of the virus in a laboratory for research purposes, they stirred grave concerns abo... Read More
In our ongoing quest for alternative energy sources, researchers are looking more to plants that grow in the wild for use in biofuels, plants such as switchgrass.
However, attempts to “domesticate” wild-growing plants have a downside, as it could make the plants more susceptible to any number... Read More
