Russian scientists have now poured 60 tonnes of freon and kerosene down the four-kilometre bore hole that plunges through the ice above Lake Vostok in Antarctica. This will stop the hole freezing up during the long Antarctic winter. When summer comes, the Russian team will return to drill the la... Read More
Aaron J. Shatkin was well known for his work on reoviruses beginning in the 1960s in his laboratory at the Roche Institute of Molecular Biology in Nutley, NJ and then at Rutgers University. He was among the first to appreciate that virus particles contained many different enzymes, such as RNA po... Read More
Buried under the seafloor for 86 million years, a bacterial community lives so slowly it's still surviving on a "lunch box" from dinosaur days, a new study says. (See marine-microbe pictures.)
It's been known since the 1990s that microbes can live trapped in ocean sediments for millions of ye... Read More
Scientists may have hit gold in their fight against dengue. They have located a human antibody that can neutralise and kill its virus within two hours.
Significantly, they have also identified a way to reproduce this antibody in large quantities, potentially opening the door to a cure for den... Read More
Children younger than 10 likely will be the most susceptible if a variant of the influenza A (H3N2) virus -- dubbed A (H3N2)v -- develops the ability to transmit easily among humans, researchers found.
Since August 2011, there have been 12 cases of infection with the variant -- which contains... Read More
After a decade of research, ContraFect Corporation, a small biotech company based in Yonkers, N.Y., is preparing to test bacteriophages—viruses that infect and destroy bacteria—in people as a potential alternative to overused antibiotics for treating and preventing bacterial infections. The firs... Read More
Jamie Henzy, a postdoctoral researcher at Boston College, has authored a post on Small Things Considered that explores the shady world of the deltaretrovirus genus.
"Among retroviruses, the deltaretrovirus genus is something of a shady bunch, its members lurking in the shadows, causing troubl... Read More
Scientists at the University of Texas Health Science Center San Antonio are investigating a potential new drug that could improve learning and memory during aging -- thanks to Easter Island?
The drug, called rapamycin, comes from isolated bacterial products in the soil of the Polynesian islan... Read More
Russian scientists said overnight a probe to a pristine lake deep under the ice of Antarctica could bring revelations on the evolution of the planet Earth and possibly even new life forms.
A Russian team drilled down to the surface of Lake Vostok, which is believed to have been covered by ice... Read More
They live on your skin, up your nose, in your gut - enough bacteria, fungi and other microbes that collected together could weigh, amazingly, a few pounds.
Now scientists have mapped just which critters normally live in or on us and where, calculating that healthy people can share their bodi... Read More
Scientists may have pinpointed a potential way to prevent the flu by identifying a protein that amps up the immune system, according to a new animal study.
The synthetic protein, called EP67, is able to trigger an immune response to the "threat" of the flu virus within a couple of hours in mi... Read More
With NASA’s Curiosity Rover safely on Mars and ready to search for signs of life, back on Earth attempts are underway to engineer bacteria that could thrive on the Red Planet.
A team of undergraduates from Stanford and Brown Universities are busy applying synthetic biology to space exploratio... Read More
The anti-vaccination movement continues to grow, despite the retraction and thorough discrediting of the 1998 scientific study that spurred much of its growth. The stubborn persistence of anti-vaxxers shows how difficult it is to dispel misinformation once that information is out there, even af... Read More
Researchers from the Translational Genomics Research Institute, the Technical University of Denmark, and elsewhere used whole-genome sequence typing to retrace the evolutionary history of a methicillin-resistant Staphylococcus aureus strain currently found in livestock back to its antibiotic-sus...

Forget needles in haystacks. Try finding the tip of a needle in a virus. Scientists have long known that a group of viruses called bacteriophages have a knack for infiltrating bacteria and that some begin their attack with a protein spike. But the tip of this spike is so small that no one knew w... Read More
Beer discovered two years ago onboard a shipwreck from the mid-1800s could possibly be recreated using living bacteria discovered in the brew, Finnish researchers announced last Thursday.
According to Terhi Kinnunen of Reuters, Annika Wilhelmson from VTT Technical Research Centre of Finland s... Read More
Insects have been around for almost 400 million years. That’s plenty of time for evolution to fashion countless horrific deaths for them. Case in point: some insects die because a little worm vomits glowing bacteria inside their bodies.
The worm is Heterorhabditis bacteriophora, a microscopic... Read More
Squishing a stack of virus sheets generates enough electricity to power a small liquid crystal display. With increased power output, these virus films might one day use the beating of your heart to power a pacemaker, the researchers behind them say.
Piezoelectric materials build up charge whe... Read More
Hi Dr Racaniello,
I am a long time listener of TWIV and really enjoy the informal scientific discussions. I listen to TWIV while working in the lab and am trying to catch up on TWIM and TWIP episodes too.
I have been dill... Read More
Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.
The scientists and other experts said the work was a giant step toward... Read More
