In addition to storing films, optical discs can be used to detect microorganisms, toxins, allergens and tumoral biomarkers. Blu-ray technology has allowed researchers to develop a way to find out if a sample contains Salmonella or toxic substances. This simple and cheap analytical system may be ... Read More

Using an experimental technique new to the dengue field, the labs of Ralph Baric, PhD, and Aravinda de Silva, PhD, showed that a molecular hinge where two regions of a protein connect is where natural human antibodies attach to dengue 3 to disable it. The finding, published in the Proceedings of... Read More
Ever since a highway construction crew in Chile uncovered a fossil graveyard of some 40 prehistoric whales in 2010, with skeletons dating back more than five million years, scientists have wondered why so many giant animals died in one place. This week, a team of them proposed an answer: The hug... Read More
The active ingredient in vinegar, acetic acid, can effectively kill mycobacteria, even highly drug-resistant Mycobacterium tuberculosis, an international team of researchers from Venezuela, France, and the US reports in mBio®, the online open-access journal of the American Society for Microbiolo...

Yeast aren’t the only microbes that help turn boring grapes into the delicious, seductive, complex, confusing, subtle, and totally splendiferous tonic known as wine. In addition to those well-known fermenters, a type of bacteria called Oenococcus oeni (for reasons that will be obvious to oenophi... Read More
In a surprising new finding, researchers have discovered that bacterial movement is impeded in flowing water, enhancing the likelihood that the microbes will attach to surfaces. The new work could have implications for the study of marine ecosystems, and for our understanding of how infections t... Read More
They have us surrounded. Even inside the spaces we build for ourselves — like homes and offices — we are a tiny minority. Invisible bacteria, fungi, and viruses outnumber us by orders of magnitude. We will always be outnumbered, but we may have a say in which microbes we’re surrounded by, accord... Read More
US doctors are warning of an emerging polio-like disease in California where up to 20 people have been infected.
A meeting of the American Academy of Neurology heard that some patients had developed paralysis in all four limbs, which had not improved with treatment.
The US is polio-free, b... Read More
Prokaryotes are by far the most successful superkingdom in terms of both biochemical diversity and the variety of environments conquered. Bacteria can be found living in all kinds of adverse conditions; from high alkaline lakes, to below freezing temperature, to hot volcanic vents which in some ... Read More
Scientists are revealing how microbes living on floating pieces of plastic marine debris affect the ocean ecosystem, and the potential harm they pose to invertebrates, humans and other animals. New research being presented here today delves deeper into the largely unexplored world of the “Plasti... Read More
Scientists have gotten close to pinning down the origin of Middle East Respiratory Syndrome, a dangerous respiratory disease that emerged in Saudi Arabia 17 months ago.
It turns out the MERS virus has been circulating in Arabian camels for more than two decades, scientists report in a study p... Read More
Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn’t used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease. In a new study in ACS’ Journal of Agricultural... Read More
If a sexually active woman wants to protect herself from unwanted pregnancy and HIV using a single method, she has always been limited to condoms. A new paper, released today in PLOS ONE details a first-of-its-kind device that provides an alternative.

Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year. University of Michigan ecologists and their colleagues are reporting the first har... Read More
One way to avoid getting sick while traveling is to only eat fruit that you peel yourself, since plants can filter out bacteria and prevent it from traveling throughout their tissues. Well, why not apply this principle to filtering water directly? A team of scientists have done just that, testi... Read More
