Scientists are reporting progress in the search for the first broad-spectrum drugs to combat human rhinoviruses (HRVs), which cause humanity’s most common infectious diseases. Their study on these potential drugs for infections that include the common cold appears in the journal ACS Medicinal Ch... Read More
The human intestinal tract, or gut, is best known for its role in digestion. But this collection of organs also plays a prominent role in the immune system. In fact, it is one of the first parts of the body that is attacked in the early stages of an HIV infection. Knowing how the virus infects c... Read More
For the first time the complex interplay between bacterial investment strategies and their outcomes has been recreated and analysed by researchers at the University of Sydney and University of Exeter.
The study is published today in the journal Ecology Letters.
Co-author Dr Tom Ferenci fro... Read More
Although the bursts of rainbow colors in this photograph are mesmerizing, microbes fight for their lives in the background. Chemist Michael P. Zach of the University of Wisconsin-Stevens Point, snapped this image of a salt sample he collected in a hot, arid valley near Death Valley National Park... Read More
For a while, Adam Martiny and some of his fellow scientists had suspected something was not right in how researchers understand the oceans. The object of their suspicion was something called the Redfield ratio, a principle stating that, when nutrients are not limiting, ocean microorganisms alway... Read More
On 4 July, good news arrived in the inbox of Ocorrafoo Cobange, a biologist at the Wassee Institute of Medicine in Asmara. It was the official letter of acceptance for a paper he had submitted 2 months earlier to the Journal of Natural Pharmaceuticals, describing the anticancer properties of a c... Read More
In 2008 researchers from the University of Southern Denmark showed that the drug thioridazine, which has previously been used to treat schizophrenia, is also a powerful weapon against antibiotic-resistant bacteria such as staphylococci (Staphylococcus aureus).
Antibiotic-resistant bacteria is... Read More
The pine-wood nematode is a major pest in the forests of China. The worm, which causes pine-wilt disease, has killed more than 50 million trees and resulted in economic losses of US$22 billion since 1982.
But now, after a study lasting almost a decade, a team of Chinese ecologists has made a ... Read More
This transmission EM of a thin section of a T2 phage infecting an E. coli cell was produced by Lee Simon in the late 1960’s. It is noteworthy for depicting a remarkably large number of properties of the phage and of the infection process. Can you figure out how many such characteristics are illu... Read More
After taking an in-depth look at the basic biology of a fungus that is decimating bat colonies as it spreads across the U.S., researchers report that they can find little that might stop the organism from spreading further and persisting indefinitely in bat caves.
Their report appears in the ... Read More
Scientists have taken an important step towards new malaria treatments by identifying a way to stop malaria parasites from multiplying.
In a study published in Nature Chemistry, they show that blocking the activity of an enzyme called NMT in the most common malaria parasite prevents mice from... Read More
When cells grow and proliferate, they need to produce large amounts of protein. All this protein is made by ribosomes, therefore rapid growth requires many ribosomes. Because ribosomes are expensive machines for the cell, the cell needs to use them efficiently. In a new study, published in PNAS,... Read More
Under favorable conditions, the microbe, a species of yeast called S. pombe, does not age the way other microbes do, the researchers said. Typically, when single-celled organisms divide in half, one half acquires the majority of older, often damaged cell material, while the other half acquires m... Read More
The cholera strain that transferred to Haiti in 2010 has multiple toxin gene mutations that may account for the severity of disease and is evolving to be more like an 1800s version of cholera, reports a new Northwestern Medicine study.
The strain, "altered El Tor," which emerged around 2000, ... Read More
We often ignore what we cannot see, and yet organisms below the soil's surface play a vital role in plant functions and ecosystem well-being. These microbes can influence a plant's genetic structure, its health, and its interactions with other plants. A new series of articles in a Special Sectio... 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
New research from the University of California, Davis suggests that blood clots may play an unexpected role in protecting the body from the effects of deadly bacteria.
Bacterial toxins, such as lipopolysaccharide (also known as endotoxin), can cause a variety of negative health effects includ... Read More
In the experiment, published this week in Nature Nanotechnology, the researchers slathered one side of a sheet of rubber with the bacterial spores. When the sheet dried it curled up, much like a leaf does after it falls from a tree. Increasing the humidity caused the sheet to straighten out agai... Read More
Red squirrels at a National Trust reserve in Merseyside have shown signs of resistance to the pox virus that has blighted the species, say researchers.
Scientists from the University of Liverpool have studied the squirrels at the Formby site for four years.
They found that 10% of its squir... Read More
Working with a nearly 200-year-old sample of preserved intestine, researchers at McMaster University and the University of Sydney have traced the bacterium behind a global cholera pandemic that killed millions – a version of the same bug that continues to strike vulnerable populations in the wor...
