Abe was then a young faculty member at nearby university and was an inspiring mentor to whom Elio gravitated straightaway. The story is a bit different for Stanley, who says: “It is f... Read More
British and Finnish scientists have found a way of generating renewable propane using a bacterium widely found in the human intestine and say the finding is a step to commercial production of a fuel that could one day be an alternative to fossil fuel reserves.
"Although we have only produced ... Read More
The Ebola virus outbreak entrenched in west Africa has become a real risk to the stability and security of society in the region, the top U.S. Centers for Disease Control and Prevention official said today after returning yesterday from a visit there.

IOHC2015 brings science and policy together aiming at the early recognition and control of emerging (infectious) diseases, now and in the years to come. Prevention at the source is the overall congress theme, as this is key in controlling (infectious) diseases that have a growing impact on human... Read More
Suzanne writes (re Aphids):
The best way to get rid of aphids in the garden (the ants in my yard love to herd them onto my okra) is a sharp stream of water from the hose. Aphids wash right off! They don't tend to come back right away, either.
Antigenic variation is a hallmark of influenza virus that allows the virus to evade host defenses. Consequently influenza vaccines need to be reformulated frequently to keep up with changing viruses. In contrast, antigenic variation is not a hallmark of poliovirus – the same poliovirus vaccines ... Read More
Vincent and Dickson discuss how infection of mice with helminths induces cytokines that reactivate a latent gamma-herpesvirus.
Dear Vincent and Dickson,
I just returned from the annual meeting of the International Society of Travel Medicine (ISTM) where I enjoyed many fantastic lectures and caught more Cutthroat Trout fly fishing the upper Snake River during one ev... Read More

But a new commentary by two leading HIV experts at Johns Hopkins argues th... Read More
About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don’t know what they do — even though these shifting cloud-like collections of proteins are believed to be crucial to the life of a c... Read More
Using magnetic fields, technique can detect parasite’s waste products in infected blood cells.
Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye... Read More
Scientists who work on genomics and are funded by the US National Institutes of Health (NIH) must post their data online so that others can build on the information, the agency has said in an update to its guidelines.
The change, which expands the remit of an earlier data-sharing policy, is ... Read More
A fast-sensitive “electronic-nose” for sniffing the highly infectious bacteria C-diff, that causes diarrhoea, temperature and stomach cramps, has been developed by a team at the University of Leicester.
Using a mass spectrometer, the research team has demonstrated that it is possible to ident... Read More
