Hello Vince and Dick,
I just found your podcast and I love it! You have some wonderfully witty banter.
I am only on my 4th episode (that's what you call a podcast segment right?), and have a question pertaining to my original reason for ... Read More
A research team led by Blossom Damania, PhD, found that suppressing the TLK enzyme causes the activation of the lytic cycle of both EBV and KSHV. During this active phase, these viruses begin to spread and replicate, and become vulnerable to anti-viral treatments.
Kaposi’s sarcoma-associated ... Read More
Throughout her career, the famous biologist Lynn Margulis (1938-2011) argued that the world of microorganisms has a much larger impact on the entire biosphere—the world of all living things—than scientists typically recognize. Now a team of scientists from universities around the world has colle... Read More
Vibrio cholerae, the scourge of nations lacking clean water. Pseudomonas aeruginosa, the microbe that plagues people with cystic fibrosis. Acinetobacter species, opportunistic organisms that can infect vulnerable people. Escherichia coli, a culprit in food-borne illnesses.
When these bacteria... Read More
It’s not as exciting as El Dorado’s source of eternal youth, but nitric oxide-producing bacteria are extending the lifespan of the humble roundworm Caenorhabditis elegans.
The worm lacks the enzyme needed to produce nitric oxide. In animals which are capable of manufacturing nitric oxide, it ... Read More
Tengo el gusto de anunciarles que mi curso de virologia esta ahora disponible en Español.
Este trabajo se realizó bajo la dirección de la Dra. Susana López, virologa del Departamento de Genética del Desarrollo y Fisiología Molecular del Instituto de Biotecnología de la Universidad Nacional A... Read More
Echinococcus granulosus is a tapeworm parasite that in its larval form can cause hydatid disease, which is characterized by cysts forming within the victim's body. In order to complete its lifecycle, the tapeworm must infect two hosts, a carnivore and a herbivore.
The adult form of Echinococc... Read More
We tend to believe -- and quite rightly so -- that germs are a detriment to our economy. The billions of dollars spent each year to treat infections can overburden the budget of any healthcare institution and the pocketbooks of anyone without appropriate health insurance.
But pathogens only m... Read More
The discovery of new viruses that appear to be spread around the world's oceans hints at a war waging between such viruses and their prey: an abundant group of bacteria.
The bacteria, collectively known as SAR11, are the most abundant organisms known to inhabit seawater.
"They are everywhere... Read More
Scientists wondering why some children and not others survived one of China's worst food safety scandals have uncovered a suspect: germs that live in the gut.
In 2008, at least six babies died and 300,000 became sick after being fed infant formula that had been deliberately and illegally tain... Read More
Elaine Hsiao is a postdoctoral fellow in chemistry and biology at Caltech. She received her undergraduate degree in microbiology, immunology and molecular genetics from UCLA and her doctoral degree in neurobiology from Caltech with Professor Paul Patterson. She studied neuroimmune mechanisms und... Read More
If you were a science professor, and you received two equally strong applications for the position of laboratory manager, one from a female, one from a male, which one would you pick? The answer may surprise you.
It is well known that women are underrepresented in many fields of science. Whet... Read More

I suspect we think of large-scale confinement agriculture as a uniquely American issue. Possibly that’s because growth-promoter antibiotic use, which makes meat-raising efficient, originated in the United States; more likely, it’s because some of the largest firms in that sector — Smithfield and...

Depending on the strain, or genotype, of the human papillomavirus (HPV), the lesions it causes can range from relatively benign to cancer-causing. Differentiating between lesions caused by low-risk and high-risk viral genotypes, however, is difficult. Françoise Thierry at the A*STAR Institute of... Read More
Genetic system performs logic operations and stores data in DNA. Synthetic biologists have developed DNA modules that perform logic operations in living cells. These ‘genetic circuits’ could be used to track key moments in a cell’s life or, at the flick of a chemical switch, change a cell’s fate... Read More
Synthetic biology delivers combination therapies into an uncertain market. “It’s been a dream project — but it’s been a long dream,” says Jay Keasling, a biochemical engineer at the University of California, Berkeley. Seven years ago, he and his team genetically engineered yeast to produce artem... Read More
US outbreak foxes a leading web-based method for tracking seasonal flu. When influenza hit early and hard in the United States this year, it quietly claimed an unacknowledged victim: one of the cutting-edge techniques being used to monitor the outbreak. A comparison with traditional surveillance... Read More
An increasing number of bacteria is evolving antibiotic resistance. Much-feared representatives of this steadily growing group include Staphylococci strains. At this point, multi-resistant forms of the bacterium Staphylococcus aureus - the "hospital germ" known commonly by its acronym, MRSA - ca... Read More
