Microbes can tailor transcriptional responses to diverse environmental challenges despite having streamlined genomes and a limited number of regulators. We present data‐driven models that capture the dynamic interplay of the environment and genome‐encoded regulatory programs of two types of prok... Read More
We may think of ourselves as just human, but we’re really a mass of microorganisms housed in a human shell. Every person alive is host to about 100 trillion bacterial cells. They outnumber human cells 10 to one and account for 99.9 percent of the unique genes in the body.
Katrina Ray, a senio... Read More
This talk was given at a local TEDx event, produced independently of the TED Conferences. How can we possibly harness evaporation and say, run the engine of a car, lift heavy weights, and generate electricity? While investigating the mysterious wrinkles seen in the protective coats of bacterial ... Read More
Those of us who write about infectious diseases faced a conundrum last week, when the news broke that 60-year-old vials containing viable smallpox virus had been found on the National Institutes of Health campus. A responsible reporter always wants to talk to the experts in any subject. But when... Read More
The day we knew would come is finally here. The first locally acquired case of the tropical disease chikungunya was reported in the U.S. today.
The mosquito-borne viral disease first debuted in the Western Hemisphere last year and has since sprawled across the Caribbean, with cases in Puerto ... Read More
Read about Angelina Fanny Hesse, an unsung heroine of microbiology who helped make the isolation of bacteria possible in this Popular Science blog post by Christina Agapakis:
"In the earliest days of microbiology, scientists were stumped about how to isolate bacteria. That is, until the fami... Read More
The symbiosis between some plant species and nitrogen-fixing nodule bacteria is one of the most relevant cooperative relationships in the world. It shapes our global vegetation and, not least, the global nitrogen and carbon cycle. The foundations for this process were probably laid in just one e... Read More
EURAC and University of Vienna discover an opportunistic pathogen in an Iceman tissue biopsy
Ötzi’s human genome was decoded from a hip bone sample taken from the 5,300 year old mummy. However the tiny sample weighing no more than 0.1 g provides so much more information. A team of scientist... Read More
Cryptococcus gattii, a virulent fungus that has invaded the Pacific Northwest, is highly adaptive and warrants global "public health vigilance," according to a study by an international team of researchers. C. gattii, which likely originated in Brazil, is responsible for dozens of deaths in rece... Read More
A new theoretical framework outlined by a Harvard scientist could help solve the mystery of how bacterial cells coordinate processes that are critical to cellular division, such as DNA replication, and how bacteria know when to divide.
For decades, scientists have believed that cellular divis... Read More
Scientists may be able to entomb the malaria parasite in a prison of its own making, researchers report. As it invades a red blood cell, the malaria parasite takes part of the host cell's membrane to build a protective compartment. The parasite then starts a series of major renovations that tran...

Unlike any other life on Earth, these extraordinary bacteria use energy in its purest form – they eat and breathe electrons – and they are everywhere
STICK an electrode in the ground, pump electrons down it, and they will come: living cells that eat electricity. We have known bacteria to surv... Read More
The TWiV team reviews the discovery of old vials of smallpox virus at NIH, anthrax and influenza mishaps at CDC, the baby who was not cured of HIV, Cambridge Working Group, and sacking of NSABB members.

Bobbi Pritt joins Vincent and Dickson to talk about directing a clinical parasitology laboratory and her weekly case reports at Creepy Dreadful Wonderful Parasites.
Hosts: Vincent Racaniello and
HI, I am Dinesh Bhandari.
I am a thesis year student of Msc. medical microbiology from Tri-Chandra campus Nepal. Currently I am doing my research in Cryptosporidium parvum and Cyclospora cayetanensis infection among School children of kathmandu at Public health research laboratory, the Institu... Read More
The U.S. education policy world—the entire country, for that matter—is on a quest to increase the ranks of future innovators in science and technology. Yet the programs that get funded in K–12 education do not support students who are already good at and in love with science. These students have... Read More
When it comes to infecting humans and animals, bacteria need a helping hand.
Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More
The Centers for Disease Control plans to take measures to better protect lab workers and the rest of us from dangerous biological samples.
Twenty-one dead lab chickens piled up this spring at a government facility before its researchers could pinpoint why. The team had requested and received ... Read More
This is the time of the year of increased physical activity when we pay special attention to certain parts of the body, including the armpit. As is usually the case, our microbiota is involved because the odor associated with sweating is produced by microbial activity. The main culprits are skin... Read More
After studying 137 varieties of cheese collected in 10 different countries, researchers have been able to identify three general types of microbial communities that live on cheese, opening the door to using each as a 'model' community for the study of whether and how various microbes and fungi c...
