Researchers have discovered why the parasite that causes the deadliest form of malaria only infects humans.
The team recently showed that the interaction between a parasite protein called RH5 and a receptor called basigin was essentially required for the invasion of red blood cells by the par... Read More
Originally discovered by accident in the 1980s, black silicon is silicon with a surface that has been modified to feature nanoscale spike structures which give the material very low reflectivity. Researchers have now found that these spikes can also destroy a wide range of bacteria, potentially ... Read More
Molecular biologists at the University of Wyoming have found a molecular mechanism that allows myxobacteria to recognize related strains that lead to the transient fusion of their outer membranes to exchange lipids and proteins.
Results of the study, led by Associate Professor Daniel Wall in ... Read More
Deep inside the dark, damp caves of Kartchner Caverns State Park lies something that sounds more suited to a fairy tale than to a rock formation.
The so-called Big Room holds the world’s largest formation of brushite moonmilk — sometimes called “elf’s milk” — a sparkling white, creamy-looking... 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
Bacteria grow faster if they feed each other. The division of labour is more efficient than a struggle through life without help from others – this is also true for microorganisms. Researchers from Research Group Experimental Ecology and Evolution at the Max Planck Institute for Chemical Ecology... Read More
Rewind Earth's story 3 or 4 billion years, to when life was emerging. The surface of our planet was starting to cool but still piping hot – possibly about 200 °C. Early, unstable continents may have been forming. Now imagine life doesn't emerge, and press play.
This is what a new computer mod... Read More
A fungus that decimates white pines has mutated and can now infect immune and resistant plants, say researchers.
This change is alarming to researchers, growers, loggers, and forest managers.
White pine blister rust (WPBR) infects white pines and Ribes, a plant genus that include gooseberr... Read More
There is much that should be remembered about those days of intensive exploratory work and much of it using very simple methods and instruments. There was a remarkable amount of sharing of current work and results without much concern for primacy, which was automatically recognized. Communicatio... Read More
Emergence of antibiotic resistance and extended spectrum β- lactamase (ESBL) among uropathogens in the pediatric unit of hospitals created serious health care concern. This study deals with antimicrobial susceptibility and ESBL analysis of uropathogenic Escherichia coli isolate... Read More
Prepare for a trip down the rabbit hole as Robert Lamb and Julie Douglas lead you on a scientific journey to the very limits of human understanding. “Stuff to Blow Your Mind” examines neurological quandaries, cosmic mysteries, evolutionary marvels and the technological advances. The link above i... Read More
St. Jude Children’s Research Hospital scientists have evidence that descendants of the H2N2 avian influenza A virus that killed millions worldwide in the 1950s still pose a threat to human health, particularly to those under 50. The research has been published in an advance online edition of the... Read More
In the perpetual darkness of a limestone cave, UA researchers have discovered a surprisingly diverse ecosystem of microbes eking out a living from not much more than drip water, rock and air. The discovery not only expands our understanding of how microbes manage to colonize every niche on the p... Read More
A group of Israeli researchers has succeeded in isolating a protein that kills bacteria, in what is a first step toward developing a substitute for antibiotics. The substance isolated by a Tel Aviv University team prevents bacteria from dividing, thus destroying them and combatting infections. “... Read More
Scientists were able to reliably predict the timing of the 2012-2013 influenza season up to nine weeks in advance of its peak. The first large-scale demonstration of the flu forecasting system by scientists at Columbia University’s Mailman School of Public Health was carried out in 108 cities ac... Read More
It is well known that aquatic birds are a major reservoir of influenza A viruses, and that pandemic human influenza virus strains of the past century derive viral genes from this pool. The recent discovery of two new influenza A viruses in bats suggests that this species may constitute another r... Read More
years of fighting the deadly and incurable virus, scientists think they may be able to find a way to really kill it. On Monday, the White House and the National Institutes of Health announced a new, $100 million effort to try to find a cure.
In the latest study, researchers tested a modified ... 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
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
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
