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

A century of Toxoplasma gondii research

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

Plate Streaking Practice

Zambian Study Finds Longer Breastfeeding Best for HIV-Infected Mothers

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

Molecular Genealogy in the Arctic Sediment

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

Contaminated water a concern in Haiti

Haiti’s next survival challenge lurks in its broken pipes, tainted wells and stagnant puddles: Water. If contaminated, it will spread disease. If stagnant, it will breed malarial mosquitoes. And if there’s no water at all, dehydration and death may follow.

“People can live without food for a ... Read More

From Throat to Mind: Strep Today, Anxiety Later?

And the debate rages on. We've posted several articles in recent months that have both said that strep is and isn't a cause for such disorders as OCD and/or tic syndromes like Tourette's. However it appears that the final word is still unclear. Here's a new article claiming, "the case for strep ... Read More

Many have had H1N1 flu, many have had a shot -- and many remain vulnerable

An estimated 18% of Americans have fallen ill with H1N1 flu, but about 20% have been vaccinated against the strain, according to new estimates released today by the U.S. Centers for Disease Control and Prevention.

The new numbers show that most of the U.S. population remains susceptible to fa... Read More

Fading H1N1 scare leaves vaccine surplus

The influenza pandemic that swept the globe and fueled concern that millions would die has led to an unprecedented glut of vaccine as fewer people than expected have sought immunization.

Governments worldwide are left with surpluses of H1N1 vaccine due to sagging demand. Many are selling or d... Read More

How do bacteria survive these low temperatures?

The bacteria whether pathogenic or not, must adapt their growth to environmental changes, such as variations in temperature Researchers at CNRS (Lab Architecture reactivity and RNA), of the University of Camerino (Italy) and Dusseldorf ( Germany) have discovered that it is the structure of RNAte...
