Small Things Considered co-blogger Merry Youle has a post about the diversity of life in McKelvey Valley, a broad, glacially-carved pass just west of McMurdo Sound in Antarctica. Her writing is inspired in part by a recent paper from the University of Hong Kong (See Read More
Genetic modification techniques have revolutionized the way life sciences firms discover and produce drugs and vaccines. They’re also poised to transform how the world produces liquid fuel.
Advances in microbial science are powering the second generation of biofuel companies, ones that are lo... Read More
Tomorrow is the start of my new virology course at Columbia University. The course, Biology W3310, is aimed at advanced undergraduates and will be taught at the Morningside Campus of Columbia University. Read More
German researchers have worked out how the malaria parasite is able to burrow through the skin and into our body.
The study of sporozoites — the highly mobile stages of the malaria parasite — is published in the January issue of the journal Cell Host & Microbe.
"We show that sporozoite mot... Read More
Plasma jets capable of obliterating tooth decay-causing bacteria could be an effective and less painful alternative to the dentist's drill, according to a new study published in the February issue of the Journal of Medical Microbiology.
Firing low temperature plasma beams at dentin -- the fib... Read More
Why does an apple a day keep the doctor away? New research published in the open access journal BMC Microbiology contributes to our understanding of why eating apples is good for you.
Microbiologists from the National Food Institute at the University of Denmark fed rats on a diet that was ric... Read More
Retroviruses such as HIV and HTLV-1 don't hit-and-run, they hit-and-hide. They slip into host cells and insert their own DNA into the cell's DNA, and from this refuge they establish an infection that lasts a lifetime.
But that infection might be much less troublesome and much more manageable ... Read More
Zebrafish need Prozac like they need a bicycle, yet recording how various molecules affect their behaviour may be the perfect way to discover treatments for mental illness and neurological diseases.
Most brain drugs are variations on 50-year-old medicines, says Randall Peterson of Massachuset... Read More
As the dreaded autumn wave ends and official deaths remain relatively low, the backlash against the H1N1 pandemic response is in full swing. Claims range from a massive overreaction by health authorities to a conspiracy cooked up by big pharma. But while swine flu may have boosted profits for va... Read More

A recent New York Times article described how China is stepping up efforts to lure home the top Chinese scholars who live and work abroad. The nation is already second only to the United States in the volume of scientific papers published, and it has, as Thomas Friedman pointed out, more student... Read More
A new study by a research team at Uppsala University shows how new functions can develop in an enzyme. This can explain, for example, how resistance to toxins can occur so simply. The findings are now being published in the Journal of Biological Chemistry.
Every biological being needs a large... Read More
Bodies piling up in Haiti pose a negligible infection risk to the public and don't need to be instantly buried or disinfected, the World Health Organization said on Monday in a report on the earthquake (PDF). Instead, relief workers should focus on treating the living.
"It is important to con... Read More
Toxoplasma gondii (Fig. 1) is a protozoan parasite that can be transmitted directly from cats to humans through faecal contamination of food, or indirectly from cats to livestock and then to humans through undercooked meat. Around 30% of humans in the United Kingdom are infected, and as such, ha... Read More
The Micro eGuide has a great series of really short tutorial videos that teach basic lab procedures. Here is the first in the series that demonstrates how to practice plate streaking. Read More
A new study from Zambia suggests that halting breastfeeding early causes more harm than good for children not infected with HIV who are born to HIV-positive mothers. Stopping breastfeeding before 18 months was associated with significant increases in mortality among these children, according to ... Read More
Heat-loving bacteria found in the Arctic seabed have their origins in oil springs and the depths of the Earth's crust. This is the finding of a project supported by the Austrian Science Fund FWF, which used molecular biology to study "misplaced" bacteria such as these. The possibility that molec... Read More
