Under a magnification of 2500X, this colorized scanning electron micrograph (SEM) revealed the presence of a large number of Gram-negative Salmonella typhimurium bacteria that had been isolated from a pure culture. See PHIL 10984 for a black and white version of this image. Read More
A unique experiment at Rice University that forces bacteria into a head-to-head competition for evolutionary dominance has yielded new insights about the way Darwinian selection plays out at the molecular level. An exacting new analysis of the experiment has revealed precisely how specific genet... Read More
Smelly feet may be the price we have to pay for saving the planet. A new study reported by New Scientist has discovered that nanoparticles commonly found in antibacterial socks may be inadvertently raising levels of greenhouse gases.
Researchers are concerned that silver nanoparticles - anti... Read More

Scientists have identified a genetic basis for determining the severity of allergic asthma in experimental models of the disease.
The study may help in the search for future therapeutic strategies to fight a growing medical problem that currently lacks effective treatments, researchers from C... Read More
The question of where and how life on Earth started has been with humans ever since the earliest days. Numerous shamans, witches, alchemists, priests and scientists attempted to uncover the answer, but their ideas and proposals oftentimes failed to produce any evidence of what they were arguing ...

An apple a day keeps the doctor away, but can knowing its genetic secrets help feed the 9 billion people expected on this planet by 2050? Scientists hope so, especially considering they have added wheat this week to the list of crops that have had their genetic instruction set read.
Wheat, w... Read More
They say Ponce de Leon looked for the Fountain of Youth in Florida, but he might have saved himself some trouble by looking a bit closer to home. A study just released by mBio links an enzyme present in almost all organisms to the reduction of age-related products called Amadori-modified protei... Read More
As efforts continue to clean the oil that gushed from the blown-out well in the Gulf of Mexico, a team of scientists has found that nature's microbial helpers are hard at work too — and doing a better job than researchers had expected.
Data collected in May and June showed populations of carb... Read More
In order to minimize the risk of infection in mothers, women giving birth to babies by caesarean section should routinely receive antibiotics an hour before the surgery, according to a new recommendation issued Monday by a national doctor group.
Currently, women who undergo caesareans often r... Read More
While people across the country have been sickened by a recent outbreak of salmonella poisoning possibly linked to eggs from Iowa producers, a Purdue University food scientist believes the poultry industry could implement a rapid egg cooling technology to reduce future outbreaks.

A drug to treat the deadly Ebola virus is one step closer today, after a new treatment was used to save infected monkeys. Clinical trials have now been approved on a small group of human volunteers in the U.S. Ebola causes death in 90 per cent of human cases but is always fatal to apes.
The ... Read More
The brain can be a convenient hiding place for HIV, the virus that causes AIDS.
That's the finding of Swedish researchers who analyzed samples from about 70 HIV-infected patients who'd been taking anti-HIV drugs. The tests showed that about 10 percent of the patients -- a larger proportion th... Read More
Researchers have linked a second type of mouse virus to a baffling condition called chronic fatigue syndrome, but said their findings do not yet prove that any virus causes the symptoms.
They found evidence of murine leukemia virus, which causes cancer in mice, in 86 percent of chronic fatigu... Read More
After more than a decade of research, Scripps Research Institute scientists have pieced together the structure of a human adenovirus -- the largest complex ever determined at atomic resolution. The new findings about the virus, which causes respiratory, eye, and gastrointestinal infections, may ... Read More
Extracts of broccoli and banana may help in fighting stomach problems, research suggests. Laboratory studies show fibres from the vegetables may boost the body's natural defences against stomach infections. Trials are under way to see if they could be used as a medical food for patients with Cro... Read More
Ontario Premier Dalton McGuinty would be better off drinking from a dog bowl than the water cooler he shares with his colleagues at Queen’s Park, a Toronto Star investigation reveals.
The Star collected and analyzed bacteria samples swabbed from spouts of 20 public water fountains and free-st... Read More
