Scientists have modified mosquitoes to produce sperm that will only create males, pioneering a fresh approach to eradicating malaria. Since 2000, increased prevention and control measures have reduced global malaria mortality rates by 42 per cent, but the disease remains a prevalent killer espec... Read More
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...

Life: Magnified is an exhibit of scientific images showing cells and other scenes of life magnified by as much as 50,000 times. The exhibit is on display at Washington Dulles International Airport's Gateway Gallery from June through November 2014.
Here we feature high-resolution versions of a... Read More
Scientists in Cork carried out a study in conjunction with the Irish Rugby Football Union which revealed that exercise and associated dietary changes influence gut microbial diversity.
The scientists at the Science Foundation Ireland-funded Alimentary Pharmabiotic Centre (APC) at University C... Read More
The use of viruses that kill bacteria as a tool for treating infections are under study again by Western researchers and governments.
For decades, patients behind the Iron Curtain were denied access to some of the best antibiotics developed in the West. To make do, the Soviet Union invested h... Read More
Scientists believe they have an explanation for the axiom that stress, emotional shock, or overexertion may trigger heart attacks in vulnerable people. Hormones released during these events appear to cause bacterial biofilms on arterial walls to disperse, allowing plaque deposits to rupture into... Read More
Pathogens entering our body only remain unnoticed for a short period. Within minutes our immune cells detect the invader and trigger an immune response. However, some viruses have developed strategies to avoid detection and elimination by our immune system. Researchers have now been able to show... Read More
Scientists say that culling a small number of badgers risks increasing the spread of TB infection to cattle.
The research suggests that some farmers who have allegedly killed badgers on their property could be making things worse for themselves and neighbours.
The findings also indicate th... Read More
Have you ever wondered why mozzarella bubbling and stretching between pizza slices is so different from the earthy flavors of blue-veined gorgonzola? The diversity of cheeses we love are created by encouraging and manipulating the growth of specific microbes. The American Socie... Read More

This educational drama was created by the International Health Board (later the International Health Division of the Rockefeller Foundation) in order to teach Southern rural communities in the United States about hookworm. Shown at fairs and other public events, "Unhooking the Hookworm" provides... Read More
Several wounded Battle of Shiloh soldiers sat in the mud for two rainy days and nights waiting for the medics. As dusk fell the first night, some of them noticed something very strange: their wounds were glowing, casting a faint light into the darkness of the battlefield. Even stranger, when the... Read More
The Norwegian Institute for Agricultural and Environmental Research, Bioforsk, has tested and implemented a set of methods for the detection of fecal pollution in Norwegian watercourses. The methods, which combine microbial and molecular biological techniques, can give answers as to whether the ... Read More
As is our custom at this time of year, we go over the material that has appeared in this blog over the last six months. Seems like a lot of stuff, but it’s the result of the work of quite a number of dedicated people, all of whom deserve our gratitude.

You could call it Seth Bordenstein’s “Frankenstein” moment. A little over a year ago, Bordenstein, a biologist at Vanderbilt University in Nashville, Tennessee, and his then-graduate student, Robert Brucker, mated two incompatible species of wasp in the lab, creating a hardy hybrid that lived wh...

A vaccine matched to a newly emerged pandemic influenza virus would require a production time of at least 6 months with current proven techniques, and so could only be used reactively after the peak of the pandemic. A pre-pandemic vaccine, although probably having lower efficacy, could be produc... Read More
The Twivsters discuss how reverse transcriptase encoded in the human genome might produce DNA copies of RNA viruses in infected cells.
For the first time, doctors have used DNA-sequencing technology to diagnose and treat a boy in an emergency. It's a big step for DNA sequencing—that the technology is able to work so quickly, and to help a patient directly. As useful as DNA sequencing is for research and genetic counseling, befo...

Babies who are exposed to both bacteria and allergens in the first year of life are less likely to develop asthma and allergies, a study finds.
It's the latest wrinkle in the hygiene hypothesis — the notion that exposure to bacteria trains the infant immune system to attack bad bugs and ignor... Read More
