Cancer, while always dangerous, truly becomes life-threatening when cancer cells begin to spread to different areas throughout the body. Now, researchers at the University of Missouri have discovered that a molecule used as a communication system by bacteria can be manipulated to prevent cancer ... Read More
Researchers say that a vaccination they have developed to fight a brain-based, wasting syndrome among deer and other animals may hold promise on two additional fronts: protecting US livestock from contracting the disease, and preventing similar brain infections in humans. Read More
Oil reservoirs are scattered deep inside the Earth like far-flung islands in the ocean, so their inhabitants might be expected to be very different, but a new study led by Dartmouth College and University of Oslo researchers shows these underground microbes are social creatures that have exchang...

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
Banana lovers take note: The world's supply of the fruit is under attack from a fungus strain that could wipe out the popular variety that Americans eat. "It's a very serious situation," said Randy Ploetz, a professor of plant pathology at the University of Florida who in 1989 originally discove... Read More
These days, antibiotics are no silver bullet. In fact, if you get them in the hospital, you may end up with an additional infection. Like the bug Clostridium difficile, or C. diff — which infects more than 300,000 Americans a year and kills some 14,000. C. diff flourishes in the post-antibiotic,... Read More
Soon, we'll have smarter, more effective vaccines. What does that mean for the future of disease?
An unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth on the outer edges of the mold colony, where spores have not yet developed, surrounding the red/pink grainy spore formation in the center of the colony. This sample grew at ...

Researchers have identified the evolutionary origins of human herpes simplex virus (HSV) -1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans -- H...

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
If you pull up a soybean or bean plant and shake off the dirt, you might see odd swellings or bumps, like rheumatic finger joints, on its roots. Inside the cool, soil-covered bumps are bacteria that are making nitrogen with the help of an enzyme, something chemical factories can do only with the... Read More
Throughout the animal kingdom, mothers transfer microbes to their young while giving birth. Different species of tadpoles acquire specific skin bacteria from mother frogs even though they all live in the same pond with the same bacterial background. Emerging chicken eggs get inoculated with micr... Read More
In a new study, published this week by the journal Royal Society Open Science, a British scientist reports the riddle of the "missing" plastic as solved: It sits in deep waters, broken down into tiny fibers and embedded in the sediment of the most remote places on Earth.

In 2012 I wrote a story for Nature about a strange illness called Kawasaki Disease whose cause has eluded scientists for over 50 years. The diseases causes inflammation of the blood vessels in small children that leads to fever, rashes and reddening, and even coronary aneurysms that can cause he... Read More
Colorectal cancer develops in what is probably the most complex environment in the human body, a place where human cells cohabitate with a colony of approximately 10 trillion bacteria, most of which are unknown. At the 2014 American Association for Cancer Research Annual Meeting in San Diego, re... Read More
Yeast cells can sometimes reverse the protein misfolding and clumping associated with diseases such as Alzheimer’s, according to new research from the University of Arizona.
The new finding contradicts the idea that once prion proteins have changed into the shape that aggregates, the change i... Read More
The test would quickly diagnose patients in remote locations where disease spread has been rampant.
Rutgers researcher David Alland, working with the California biotechnology company Cepheid, has received a grant of nearly $640,000 from the National Institutes of Health to develop a rapid tes... Read More
One of the food industry’s major recurring challenges, detecting highly carcinogenic toxins that occur naturally in our most common crops, could soon be solved by groundbreaking research that exploits aflatoxins’ fluorescent properties.
Aflatoxins are present in a wide... Read More
Vincent, Dickson, and Daniel provide the solution to last week's case study, present a new one, and discuss how immune suppression by nematodes increases tuberculosis fatality in African buffalo.
These clinical isolates are from Medinipur Medical College. Read More
