New Visible Light Photocatalyst Kills Bacteria, Even After Light Turned Off

In the battle against bacteria, researchers at the University of Illinois have developed a powerful new weapon -- an enhanced photocatalytic disinfection process that uses visible light to destroy harmful bacteria and viruses, even in the dark.

Based upon a new catalyst, the disinfection proc... Read More

In sync: Squid, glowing companions march in genetic harmony

Most humans are blissfully unaware that we owe our healthful existence to trillions of microbes that make their home in the nooks and crannies of the human body, primarily the gut.

During evolutionary history, humans and bacteria have forged a mutually beneficial coexistence that provides the... Read More

Microbe Theater - Episode 9

How to make Surströmming, "soured herring," a northern Swedish delicacy consisting of fermented Baltic herring. Careful though, several major airlines have banned this canned delight by declaring it "potentially explosive" since the fermentation process in the can is ongoing.

Cryptic Life in the Antarctic Dry Valleys

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

Microbial research spawns new generation of biofuels

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

A new virology course at Columbia University

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

Malaria bug enters skin using sticky patches

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

Painless Plasma Jets Could Replace Dentist's Drill

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

Friendly Bacteria Love the Humble Apple

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

Early immune response needed for hit-and-hide cancer viruses

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 make good 'guinea pigs' for human drugs

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

Analysis: Swine flu is not just a hoax by big pharma

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

Will China Achieve Science Supremacy?

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

Minimal Changes Alter an Enzyme Dramatically

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

No health risk from Haiti dead bodies

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
