I guess it doesn't sting, which is a plus - clearly we need no more stinging/biting/blood-sucking creatures on this earth - but my real wonder is what's next, and why rat heart muscle? Read More
How cool is that to be listening to you all reading my emails with Peter Sandman while I am stuck in traffic.
I loved the discussion and want to send a big thank you to Michael for joining in and giving us the missing perspective of what the NSABB ... Read More
Researchers at the College of Life Sciences have identified fexinidazole as a possible, much-needed, new treatment for the parasitic disease visceral leishmaniasis.
Leishmaniasis is named after William Leishman, a Glasgwegian doctor serving with the British Army in India, who first identified... Read More
Conventional wisdom says that in order for a species of insect to develop resistance to an antibiotic, several generations have to pass, whereby genes from those that have some natural resistance pass them on to their offspring. But sometimes conventional wisdom fails to take into account how so... Read More
We’ve all heard the claims of probiotic yogurts and their benefits for human health, but aside from improving our belly dancing skills, what exactly are probiotic bacteria doing?
An elegant study from the Jeffrey Gordon lab explored the effects of consuming fermented milk products (FMPs) cont... Read More
Some viruses that infect bacteria (bacteriophages) deliver their DNA into the host cell with an amazing injection machine. The tailed bacteriophages (such as T4, illustrated) store their DNA in a capsid attached to a long tail tube that is surrounded by a sheath. At the bottom of the tube is a b... Read More
In 1969 David Baltimore proposed that poliovirus RNA replication is coupled with packaging, in that only those genomes actively replicating will be selectively encapsidated. From an evolutionary standpoint, it is an ingenious requirement to ensure that only virus genomes capable of replication ... Read More
At first glance, the inaugural 1812 issue of the New England Journal of Medicine and Surgery, and the Collateral Branches of Science seems reassuringly familiar: a review of angina pectoris, articles on infant diarrhea and burns. The apparent similarity to today's Journal, however, obscures a fu... Read More
If you know anything about snakes you might be familiar with snake inclusion body disease, or IBD. This transmissible and fatal disease affects snakes of a variety of species but has been best studied in boas. The name comes from the presence of large masses (inclusions) in the cytoplasm of cell... Read More
New research shows that killer whales are inhaling bacteria, fungi and viruses once believed to be found only on land. Some of the pathogens are highly virulent. And some are even antibiotic-resistant.
The scientists followed the killer whales by boat, trying to catch the precise moment the a... Read More
