Fungal and bacterial pathogens are quite capable of infecting plants, animals and humans despite their immune systems. Fungi penetrate leafs, stalks and roots, or skin, intestines and lungs, to infect their hosts. Researchers from Wageningen UR (University & Research centre) discovered, together... Read More

A drug to treat inflammation plays a surprising role reducing the level of infection caused by an opportunistic bug that is deadly for AIDS and cancer patients and others with weakened immune systems.
The drug, sulfasalazine, spurs the body to get rid of the fungal evaders by enhancing the bo... Read More
For Africans wondering whether the malaria drugs they've bought are real, there may soon be a quick way of finding out: sending a text message.
Across the continent, more than 30 percent of malaria medicines are estimated to be fake, and many look identical to the real thing.

A massive oil plume from the Deepwater Horizon blowout may survive for longer than expected against the petroleum-eating microbes in the Gulf of Mexico, according to a new study.
Researchers took a "forensic snapshot" in late June that showed higher-than-expected oxygen levels in the plume fr... Read More
Researchers may have found a new form of chlorophyll, the pigment that plants, algae and cyanobacteria use to obtain energy from light through photosynthesis. Preliminary findings published August 19 in Science suggest that the newly discovered molecule, dubbed chlorophyll f, has a distinct che... Read More
The U.S. government released a new plan on Thursday for cutting red tape and working more closely with companies to prepare for the next big biological disaster -- be it a flu pandemic or nuclear attack.
The plan from the Health and Human Services Department directly addresses many of the com... Read More
A new compound may offer an effective drug candidate against the deadly tropical infection, Chagas’ disease say researchers from Brazil. They report their findings in the August 2010 issue of the journal Antimicrobial Agents and Chemotherapy.
Chagas’ disease is an infection caused by the par... Read More
A naturally occurring virus in mosquitoes may serve as a “late-life-acting” insecticide by killing older adult mosquitoes that are responsible for the bulk of malaria transmission. The researchers from Johns Hopkins University and the Johns Hopkins Malaria Research Institute, Baltimore, Maryla... Read More
Highly pathogenic avian influenza virus (H5N1) may persist on feathers fallen from the bodies of infected domestic ducks and contribute to environmental contamination. Researchers from the National Institute of Animal Health, Tsukuba, Ibaraki, Japan report their findings in the August 2010 issu... Read More
The human genome is riddled with dead genes, fossils of a sort, dating back hundreds of thousands of years — the genome’s equivalent of an attic full of broken and useless junk.
Some of those genes, surprised geneticists reported Thursday, can rise from the dead like zombies, waking up to ca... Read More
In May, days after a group of high school students in the Bay Area nibbled on custard-filled pastries at a catered prom dinner, several of them started to complain about aching stomachs. Around the same time, some college students celebrating their graduation used the same catering company — and... Read More
The oldest evidence of a fungus that turns ants into zombies and makes them stagger to their death has been uncovered by scientists.
The gruesome hallmark of the fungus's handiwork was found on the leaves of plants that grew in Messel, near Darmstadt in Germany, 48m years ago.
The finding ... Read More
Following up a pioneering 2007 proof-of-concept study, a University of Utah biochemist and colleagues have developed a promising new anti-HIV drug candidate, PIE12-trimer, that prevents HIV from attacking human cells.
Michael S. Kay, M.D., Ph.D., associate professor of biochemistry in the Uni... Read More
Conventional thinking says that animal immune systems have evolved to defend against harmful microorganisms, but a new Cornell study examines the role of friendly bacteria in shaping animal immunity.
All animals are colonized by bacteria -- in fact, humans have 10 times as many bacteria as ce... Read More
Mosquitoes that carry the Plasmodium parasite cause some 300 million cases of malaria every year, claiming one million lives. That's a lot of carnage generated by an insect smaller than a pinky fingernail—but if enterprising researchers have their way, their blood-thirsty assault won't continue... Read More
Before you make breakfast, check the egg carton. Does it bear the name Lucerne, Albertson, Mountain Dairy, Ralph’s, Boomsma’s, Sunshine, Hillandale, Trafficanda, Farm Fresh, Shoreland, Lund, Dutch Farms or Kemps?
If so, those scrambled eggs may have to wait.

A cheap and effective filtering device developed by a South African university could provide safe drinking water to millions of people, drastically reducing the incidence of waterborne illnesses such as cholera and other diarrhoeal diseases.
The device resembles a teabag in both size and shap... Read More
