Earlier this week, Yoshinori Ohsumi was awarded the 2016 Nobel Prize in Physiology or Medicine for his work on the underlying mechanisms of autophagy—the process by which cells break down and recycle their own contents. How does autophagy work? Here are the basics, as drawn for the article “How ... Read More
New research reveals that in pregnant women, Zika virus infection damages certain cells that affect placental formation and function. Furthermore, herpes simplex virus-2 (HSV-2) infection augments placental sensitivity to Zika virus by enhancing the expression of receptors that allow Zika virus ... Read More
Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for thousands of deaths around the world each year. However, because the bacteria are resistant to many different antibiotics, treatment options are limited, and often ineffective.
But until now scientists didn't know how MRSA ... Read More

The bad news for people who suffer from migraines is that the debilitating headaches may be caused by some of your favorite foods.
Everyone who gets migraines can identify the symptoms: increased sensitivity to light and noise, blurred vision and dull throbbing in the head.
A new study by ... Read More
One of the ultimate goals of Mars exploration is to bring samples from the surface to Earth, especially those that could be examined for evidence of life on the Red Planet.
Such an undertaking would be expensive and the samples risk contamination during their journey to Earth. So, one option ... Read More
Chemosynthetic symbionts are bacteria living inside or on the surface of animals, supplying their host with food that would otherwise be unavailable. It has long been known that these bacteria fix carbon and convert it into organic forms. Microbiologist Jillian Petersen and colleagues from the U... Read More
Scientists have tried to alter the human gut microbiota to improve health by introducing beneficial probiotic bacteria. Yet commercially available probiotics do not establish themselves in the gut. A study published September 29 in Cell Host & Microbe suggests that it is possible to alter the mi... Read More
In the new study, the scientists observed the virus's effects in animal models at two different points -- during early postnatal development, when the brain is growing rapidly, and at weaning, when the brain has largely reached adult size.
"In early postnatal Zika-infected models some brain a... Read More
The number of cases of Zika virus detected in Australia is now up to 76, with seven cases diagnosed this year in Far North Queensland.
The latest figures from the Federal Health Department show travellers arriving from countries such as Fiji, Tonga and Mexico have brought the virus to Austral... Read More
About 100 million years ago, a lowly amoeba pulled off a stunning heist, grabbing genes from an unsuspecting bacterium to replace those it had lost.
Now Rutgers and other scientists have solved the mystery of how the little amoeba, Paulinella, committed the theft. It engulfed the bacterium, k... Read More
Avid mushroom hunters will tell you that fire is essential for finding morels. These fungi, distinguishable for their dark, honeycomblike caps, pop out of the ground by the bushel in spring after a large wildfire.
This ecological knowledge is mostly anecdotal, shared among morel enthusiasts f... Read More
The TWiVome reveal the first eukaryotic genes found in a bacteriophage of Wolbachia, and how DNA tumor virus oncogenes antagonize sensing of cytoplasmic DNA by the cell.
Exciting new research in the medical journal MBio, the journal of the American Society for Microbiology, offers hope for sufferers of the debilitating illness known as Crohn’s Disease.
Crohn’s is an inflammatory bowel disease (IBD) that involves inflammation of the lining of the bowels and th... Read More
A study published today in Ecology Letters adds to a growing body of work examining the relationship between harmful algal blooms in the Gulf of Mexico and agricultural runoff. The article focuses on water chemistry, specifically the ratio of dissolved silica to dissolved inorganic nitrogen in 1... Read More

Yoshinori Ohsumi, a Japanese cell biologist and ASM member, was awarded the Nobel Prize in Physiology or Medicine on Monday for his discoveries on how cells recycle their content, a process known as autophagy.
In a series of experiments in the early 1990s, Dr. Ohsumi used baker’s yeast to ide... Read More
Currently, it is well established that prokaryotes possess cytoskeleton and organelles. This image depicts how magnetic organelles, magnetosomes, are properly partitioned and segregated by a mechanism that relies on the treadmilling of a dedicated cytoskeletal structure, the actin-like MamK fila...

A Biosecurity Research Institute study has found important results in the fight against Zika virus: Culex mosquitoes do not appear to transmit Zika virus.
Researchers at Kansas State University's Biosecurity Research Institute studied Culex species mosquitoes from across the country, includin... Read More
A new drug combination helped stave off a monkey version of HIV for nearly two years after stopping all treatments, raising hopes for a functional cure for HIV, U.S. researchers said on Thursday.
The treatment involved standard HIV drugs, known as antiretroviral therapy or ART, plus an experi... Read More
