A new study confirming the existence of a massive plume of oil trapped deep underwater in the Gulf of Mexico defies notions that bacteria, while they are degrading the oil, will make as quick work of petroleum lingering in the water's cold depths as they have on the surface.
In a widely hail... Read More
The salmonella outbreak that led to the recall of 380 million eggs was preventable and will likely grow, federal officials said Thursday.
Hundreds of Americans likely have become ill from tainted eggs in recent months, according to estimates from the Centers for Disease Control and Prevention... Read More
HIV-1 in semen is different than HIV-1 in blood, possibly due to changes it undergoes in the genital tract, scientists have found.
In their study, the researchers sought to better understand the process by which HIV -- the virus that causes AIDS -- is transmitted. They compared the gene encod... Read More
The world of virology lost two notables in recent weeks, offering an opportunity to reflect on the differences they made -- and to look ahead at advances yet to come.
The names may be unfamiliar; what they wrought isn't.
Dr. Robert M. Chanock not only isolated the respiratory syncytial vir... Read More
Slipping beneath the waves on April 15, 1912, the R.M.S. Titanic famously disappeared from view until 1985, when it was rediscovered on the bottom of the North Atlantic.
Now, scientists say, the legendary liner—beset by metal-eating life-forms, powerful currents, and possibly even human negl... Read More
In another blow to the nation's $6-billion egg industry, a second Iowa producer issued a recall of 170 million eggs that could be contaminated with salmonella — bringing the total number to more than half a billion.
The eggs were produced by Hillandale Farms of New Hampton, Iowa, and package... Read More
Brushing your teeth is a regular ritual for most people, and normally that involves both a toothbrush and toothpaste to remove the gunk that builds up on our teeth and gums. The solar toothbrush looks to eliminate the paste, harnessing the power of the sun to kill off all that nasty bacteria.

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 new project... Read More
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
