Whether they admit it or not, many (if not most) scientists secretly hope to get a call in October informing them they've won a Nobel Prize.
But I've talked to a lot of Nobel laureates, and they are unanimous on one point: None of them pursued a research topic with the intention of winning th... Read More
Extreme adaptations of species often cause such significant changes that their evolutionary history is difficult to reconstruct. Zoologists have now discovered a new parasite species that represents the missing link between fungi and an extreme group of parasites. Researchers are now able to und... Read More
Humans are not the only primates ravaged by the deadly Ebola virus. Chimps and gorillas are also susceptible to the disease. The current Ebola epidemic, the biggest in human history, may have started with the butchering of an infected fruit bat. But it just as easily could have come from a chimp... Read More
Fecal transplants can be life-saving for people with stubborn bacterial infections, but they're not for the faint of heart. So doctors have come up with a way to make them more palatable – the frozen poop pill.
People infected with Clostridium difficile suffer debilitating diarrhea, but the b... Read More
From joint replacements to cardiac implants and dialysis machines, medical devices enhance or save lives on a daily basis. However, any device implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient the device is meant to hel... Read More
The Epstein–Barr virus and its relatives in the herpesvirus family are known for their longevity. They persist in host tissues for years, causing diseases like mononucleosis, Kaposi's sarcoma and herpes, and are notoriously difficult to kill. University of California, Los Angeles, biophysicist Z... Read More
Studying chromosome organization in bacteria. Over the last twenty years, molecular biologists developed and refined a downright cute method to study bacterial chromosome organization in live cells. Briefly, a cluster of binding sites for a DNA-binding protein is introduced at a chosen locus of ... Read More

The Liberian man who was diagnosed with Ebola virus infection after traveling to Dallas, Texas, was treated with an antiviral drug called brincidofovir. This drug had originally been developed to treat infections with DNA-containing viruses. Why was it used to treat an Ebola virus infection? Read More
The time before the symptoms of a viral infection appear is called the incubation period. During this time, viral genomes are replicating and the host is responding, producing cytokines such as interferon that can have global effects, leading to the classical symptoms of an acute infection (e.g....

In February 2014 I wrote about children in California who developed a poliomyelitis-like paralysis, also called acute flaccid paralysis or AFP. However, the cause of this paralysis was not known. The CDC has released its study of these cases and concludes “The etiology of AFP with anterior myeli... Read More
Two randomized trials in the October 8 issue of JAMA examine new vaccination strategies for the prevention and control of avian influenza, often referred to as “bird flu.” This is a theme issue on infectious disease.
In one study, Mark J. Mulligan, M.D., of the Emory University School of Medi... Read More
Viruses can convert their DNA from solid to fluid form, which explains how viruses manage to eject DNA into the cells of their victims. This has been shown in two new studies carried out by Lund University in Sweden.
Both research studies are about the same discovery made for two different vi... Read More
Multiple sclerosis (MS) is an electrical disorder, or rather one of impaired myelin, a fatty, insulating substance that better allows electric current to bolt down our neurons and release the neurotransmitters that help run our bodies and brains. Researchers have speculated for some time that th... Read More
Creating and maintaining a clean, sustainable water supply means delivering drinking water and collecting wastewater while dealing with pathogenic microorganisms and infrastructure challenges. It's not all challenges, however. Two speakers; Sudhir Murthy, PhD, PE, BCEE, Innovation Chief at DC... Read More
The HIV pandemic with us today is almost certain to have begun its global spread from Kinshasa, the capital of the Democratic Republic of the Congo (DRC), according to a new study.
An international team, led by Oxford University and University of Leuven scientists, has reconstructed the genet... Read More
Targets to eliminate tuberculosis by 2050 are more likely to be met if new vaccines are developed for adults and adolescents instead of for infants, according to new research.
Researchers at the London School of Hygiene & Tropical Medicine and the Stop TB Department at the World Health Organi... Read More
