When astronauts launch into space, a microbial entourage follows. And the sheer number of these followers would give celebrities on Twitter a run for their money. The estimate is that normal, healthy adults have ten times as many microbial cells as human cells within their bodies; countless more... Read More
Frog-killing fungi, the methods bacteria use to evade antibiotics, and the hidden microbes deep inside an Antarctic lake: These are just a few of the topics covered in “Small Things Considered,” a microbiology blog run by Moselio Schaechter. Schaechter is former president of the American Society... Read More
Children hospitalized for pneumonia have similar outcomes, including length of stay and costs, regardless of whether they are treated with “big gun” antibiotics such as ceftriaxone or cefotaxime or more narrowly focused antibiotics such as ampicillin or penicillin, according to a Vanderbilt stud...

If you aren’t familiar with the TEDEd series of animated videos, you should be. The series pairs professional educators with top-notch animators to create short video “lessons” on a huge variety of topics in science, medicine and history. The latest episode features several of the early attempt... Read More
A newly discovered fungus that feasts on the skin of amphibians is threatening to decimate a species of salamander in the Netherlands, according to new research.
Fire salamanders are one of the most recognizable salamander species in Europe, and are characterized by their distinct yellow- and... Read More
The world’s only twin astronauts will take center stage in an upcoming NASA experiment that will analyze whether or not identical siblings remain the same biologically if one travels to outer space while the other remains on Earth.
According to the US space agency, astronaut Scott Kelly will ... Read More
The researcher Manuel Palacín, head of the Heterogenic and Multigenic Diseases lab at the Institute for Research in Biomedicine (IRB), in Barcelona, is among the world’s experts in HATs (heteromeric amino acid transporters).
In humans, there are eight HAT molecules. These are associated, for ... Read More
Five years after implementing a national initiative to reduce methicillin-resistant Staphylococcus aureus (MRSA) rates in Veterans Affairs (VA) medical centers, MRSA cases have continued to decline, according to a study in the November issue of the American Journal of Infection Control, the offi...

Owls are the natural predators of the rats carrying the deadly hantavirus, the Santiago Times newspaper reports. Long-tailed pygmy rice rats transmit the virus to humans as they come into contact with campers in the forest, while foraging for bamboo. But forest fires during Chile's summer months... Read More
Evolution is one of those enigmatic subjects we simply do not understand fully. We know it is a biological change at the genetic level that changes the overall nature of an organism. We're also sure that it requires a significant number of generations. Unfortunately, that means it is difficult t... Read More
Forty years ago, a beloved neighbor was bedridden for weeks at a time with a mysterious ailment. She knew only that it involved her liver and that she must never drink alcohol, which would make things worse.
It was decades before the cause of these debilitating flare-ups was discovered: a vir... Read More
A new way to attack flu viruses is taking shape in laboratories at Rutgers University, where scientists have identified chemical agents that block the virus’s ability to replicate itself in cell culture.
These novel compounds show promise for a new class of antiviral medicines to fight much-f... Read More
Finding that part of the story of Louis Pasteur's rabies vaccine is false, Héloïse Dufour and Sean Carroll explore how science fables are born, spread and die.
John Snow's ending of London's 1854 cholera outbreak, Joseph Lister's development of antiseptic surgery, Alexander Fleming's inventio... Read More
Here I remember a person who a great deal of influence on my views about microbiology in the classroom, and the laboratory: the late Abigail Salyers. RIP, Abigail. Read More
To know how many proteins assemble together at the nanoscale is fundamental for understanding protein function. Sometimes, proteins must be in an "oligomeric" state to be functional, although "oligomerization" of certain proteins can also lead to diseases. The ability to determine protein stoich... Read More
We’re driving on a dirt road and my interpreter, one of the friendliest guys I’ve ever met, is absorbed in a conversation with a health worker in our group. Cornfields and rice paddies paint the landscape chartreuse. Donkey carts and herds of goats swerve into the plants when we rumble past. The... Read More
By tinkering with their chemical structures, researchers at the University of California, San Diego School of Medicine have essentially re-invented a class of popular antimicrobial drugs, restoring and in some cases, expanding or improving, their effectiveness against drug-resistant pathogens in...

Scientists at Emory Vaccine Center have found a link between immunity induced by vaccination and an ancient way that cells adapt to scarcity, a link that could help researchers develop vaccines against challenging infections such as HIV or malaria.
Researchers studying immune responses to the... Read More
MY GLOBAL VIDEO CHALLENGE (HOW MY SCIENCE AFFECTS MY COMMUNITY.)
Sometimes I wonder why diseases like typhoid fever and malaria lingers in West Africa and antibiotic as well as anti-malaria usage rises to resistant levels, until I met this community during one of my outreach trips. It was unima... Read More
