Looking for population shifts on satellite images could be a way to deliver vaccines and prevent or control disease outbreaks, a new study finds.
The findings, published in Scientific Reports, are based on analysis of satellite images, vaccine records, and measles case reports.
The researc... Read More
Aaron E. Carroll, professor of pediatrics at Indiana University School of Medicine, discusses the five-second rule about dropping food on the floor and still eating it. He reminds us that we touch lots of dirty surfaces everyday, from cell phone screens to money and even the kitchen sink sponge.... Read More
Daniel Haeusser, an Assistant Professor in the Biology Department of Canisius College in Buffalo, New York, discusses the misconception of assuming that photosynthesis exists as single process of strict coupling between energy conversion and carbohydrate production. Read More

A popular antibiotic called rifampicin, used to treat tuberculosis, leprosy, and Legionnaire’s disease, is becoming less effective as the bacteria that cause the diseases develop more resistance.
One of the mechanisms leading to rifampicin’s resistance is the action of the enzyme Rifampicin m... Read More
Cells never forget to take out the trash. It has long been known that cells tag proteins for degradation by labelling them with ubiquitin, a signal described as "the molecular kiss of death". Tim Clausen's group at the Research Institute of Molecular Pathology (IMP) in Vienna identified an analo... Read More
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
A Nutrient agar plate exposed to air for few minuts shows the truth of world well. after a overnight incubation at room temparature. A small but significant fungus colony prevents growth of large fungus colony.
Same thing happens in our world mannier times when small people (so c... Read More
Sharon and Scott join the TWiV team to talk about their work on dengue antibody-dependent enhancement of Zika virus infection, and identifying the virus in mosquitoes from Miami.
Happy bacteria couple drawn on TSA plate using a MRSA culture.
This picture illustrates how happy bacteria can become when people don't take all the antibiotic treatment correctly. Antibiotic resistance is a big problem nowadays. Read More
There is a growing popular and policy interest in the microbiome, and the possibilities of more nuanced or ‘probiotic’ ways of living with germs. To date however there has been limited public engagement with the science and technology of metagenomics. The project engages with the growing scienti... Read More
The natural presence of fatty acids in the human body leads to increased resistance of Staphylococcus aureus to a class of antimicrobials that target bacterial fatty acid biosynthesis. This discovery, based on research by INRA scientists in collaboration with with INSERM, Hôpital Cochin APHP, th... Read More
Colostrum is a thick, sticky, yellowish mammary secretion that all mammals provide to their newborns during the first 24-48 hours after delivery.
It has been reported that constituents from BC are 100-fold to 1,000-fold more potent than human colostrum. This means that even human infants can ... Read More
A new tool that uses a forest-like array of vertically-aligned carbon nanotubes that can be finely tuned to selectively trap viruses by their size can increase the detection threshold for viruses and speed the process of identifying newly-emerging viruses.
"Early detection is important becau... Read More
Researchers have discovered the strongest evidence yet linking the Zika virus to the paralytic illness Guillain-Barre syndrome. During the height of the viral epidemic the incidence of Guillain-Barre was 100 times the number of cases usually seen.
Guillain-Barre is a normally rare condition t... Read More
Laboratory tests show that a cold-tolerant mosquito known as Culex quinquefasciatus can be infected with Zika virus in the laboratory. If confirmed in the field, it would be a troubling development, suggesting the virus would be more difficult to control, and might be able to spread far north of... Read More
Dengue fever infects 390 million people each year, and kills as many as 25,000, according to the World Health Organization.
The disease could soon see these numbers decline as the Philippines start administering the world's first dengue vaccine to high-risk children.
The historic drug took... Read More
The TWiM team discusses the importance of neutrophils in microbial infections, and evidence that ancient bacteria had two cell walls.
Here's an interesting little historic snippet from The Lancet.
