University of Michigan researchers say they have identified what appears to be a crucial step in the chain of biological events leading to post-traumatic stress disorder.
Their findings support the idea that exposure to a traumatic event can trigger genetic changes that alter the body's immun... Read More
During my visit to Berkeley, CA to record TWiV #228, I met Deb Sklut, an artist who is inspired by the power of science. I recorded a brief conversation with Deb which you can view below. Her work can be found at SqueakySqueegeeArt.etsy.com. Read More
Global Viral Forecasting Founder Nathan Wolfe explains how his team is searching for humanity's next great plague... so we can stop it before it spreads.
This is an accurate visualization of the Bacteriophage T4 based on Cryo-EM datasets of the virus. The scope of the animation is to show the infection process of the T4 into an E. coli cell. All scientific data sets and motion based off of research from Michael Rossmann Laboratory (Purdue Univers... Read More
Without the awesome power of microbes, these wonders of the ancient world would never have been built! Everyone knows about the awesome number of stone blocks and huge manpower requirements, but few know the important role that yeast had to play in building the pyramids. Read More
Scientists fear the mosquito-borne virus, Chikungunya, which has infected tens of thousands of people in Papua New Guinea, could spread to Australia.
The virus, which originated in Africa, is similar to dengue and causes debilitating joint pain, rashes and fever.
Amid an outbreak of the vi... Read More
The bacteria that cause syphilis and Lyme Disease have something extraordinary in common: they manage to propel themselves through their environment in spite of the fact their tails are located inside their bodies.
For bacteria, they’re also unusually shaped and active. In this movie, you can... Read More
Biologists dissected tissue samples from an oarfish carcass found in California and discovered the creature was hosting quite a few parasites.
“Our findings say that these are actually majorly parasitized fish,” says Armand Kuris, professor of zoology at the University of California, Santa Ba... Read More

Plant genome research is already revolutionizing the field of biology. Currently, scientists are unlocking the secrets of some of the most important plants in our lives, including corn, cotton and potatoes. Secrets of Plant Genomes: Revealed! takes viewers on a lively, upbeat journey that explor... Read More
Public health crises of the past decade — such as the 2003 SARS outbreak, which spread to 37 countries and caused about 1,000 deaths, and the 2009 H1N1 flu pandemic that killed about 300,000 people worldwide — have heightened awareness that new viruses or bacteria could spread quickly across the...

It could be a breakthrough in the hunt for an "elixir of life". Organic molecules containing a heavy isotope of hydrogen seem to resist the kind of cell damage that happens with ageing. But hang on to your moisturiser for now: the effects have been demonstrated only in yeast cells.
Free radic... Read More

Alex Fiorentino describes how the Whitesides lab at Harvard is developing sophisticated medical diagnostic devices that are lightweight, disposable, cost pennies to make, and operate without power. They're made out of paper. Read More
If we could somehow rewind the history of life to the dawn of the animal kingdom, it would be unlikely that we humans would ever evolve, the evolutionary biologist Stephen Jay Gould argued. The history of life was shaped by too many flukes and contingencies to repeat its course.
Scientists ca... Read More
Membrane proteins are the “gatekeepers” that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of “force microscopes” that are available to researchers and the one-dimensional res...

Recent clinical tests demonstrate that antimicrobial copper is effective in significantly reducing the bacterial load in intensive care unit (ICU) patient rooms and on many individual objects in those rooms. Results from a U.S. Department of Defense-funded clinical trial assessing the ability of... Read More
