Addie Rerecich was a happy 11-year-old girl who loved sports and talked a mile a minute. But when a mysterious pain in her hip landed her in the hospital in 2011, she began a downward spiral into ... Read More
It might sound strange to say that humans have forgotten what human-food is, but many scientists believe this is the case. For thousands of years, the environment in which humans lived evolved at a glacial pace—our nutrition and culture changed slowly, and our bodies adapted to it at a matching ... Read More
This is an 3D image of conidiophores of the filamentous fungus Neurospora crassa. Conidiophores are hyphae which differentiate to produce asexual structures named spores or conidia. The image taken using a confocal microscope shows conidiophores stained with a fluorophore which stains components... Read More
A UCLA-led team of researchers has found evidence that photosensitizing a virus's membrane covering can inhibit its ability to enter cells and potentially lead to the development of stronger, cheaper medications to fight a host of tough viruses.
The UCLA AIDS Institute study, published in th... Read More
Q) Dr. Tim Sandle, the well known researcher, professor, author and science communicator. It is much interesting for me to take an interview of an eminent person who is well known for the communicating science. Starting from your early childhood life, how you used to take science as that time?

A Virginia brewer soon plans to serve a beer made from yeast found hanging out on a 40-million-year-old whale fossil, the blog Symbiartic reports. Depending on your disposition, I imagine you're reacting in one of two ways right now, "Yecchh!" or "Cool!" The beer will be called Bone Dusters Pale... Read More
Many people have heard that human urine is devoid of germs, but a new study seems to question that idea.
"Doctors have been trained to believe that urine is germ-free," Dr. Linda Brubaker, dean of Loyola University Chicago Stritch School of Medicine, said in a university news release. "These ... Read More
Our vaccine unit here at NIH did a study of malaria vaccine with some promising results. I know Dickson has been a champion of conquering malaria.
Germaphobes, maybe you're on to something.
Sickness-causing bacteria and viruses can lurk on surfaces long after they're expelled in an infected person's sneeze or snot. Some can even stay on a surface for months, given the right conditions. While the ability of these microorganisms to actual... Read More
How long does it take to become a microbiologist?
I'd never heard of magnetotactic bacteria before and thought perhaps you guys might find this interesting. Not sure if you've mentioned these on TWIM before,... Read More
A new class of molecules called acyldepsipeptides—ADEPs—may provide a new way to attack bacteria that have developed resistance to antibiotics.
Researchers have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemica... Read More
For the millions of people forced to rely on a plastic tube to eliminate their urine, developing an infection is nearly a 100 percent guarantee after just four weeks. But with the help of a little bubble-blowing, biomedical engineers hope to bring relief to urethras everywhere.
About half of ... Read More
From ocean floors to office desks, bacteria coat nearly every inch of the Earth. Scientists have recently discovered bacteria are present high above the Earth, as well. Ten kilometers up, to be exact, in a region of our atmosphere known as the upper troposphere. In a place where freezing tempera... Read More

Many bacteria have a trick for surviving a water shortage: They dry up like raisins and turn into spores, protecting their essential genetic code. But moisten a spore and it swells right up again.
Those capabilities give bacterial spores some interesting potential as an energy source, as scie... Read More
Of all the public transit etiquette violations out there, the sneeze-and-touch at the height of cold and flu season is among the worst. Everyone who rides in a city has seen it: that sickly looking person across the train or bus who sneezes into a free hand then grabs the pole we all share. Rese... Read More
Serratia marcesens is a Gram-negative, rod-shaped bacterium that is commonly found in soil, water, on plants and in animals and thrives in damp conditions. This organism is well known for its production of the blood red pigment, prodigiosin. Production of prodigiosin can be influenced by several... Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More
