Snake venom composition may change according to the victim

A snake's intended prey might affect the type and evolution of toxins in their venom, research published in the online open access journal BMC Evolutionary Biology shows.

Test for lung cancer looks for discomforting quiet among protective genes

When it is quiet – "almost too quiet" – in movies, it is a sign that something is about to go wrong for the good guys.

New DNA technique will speed up chemical compensation claims

A new DNA technique developed by scientists in the U.S. may help prove if people have had their health damaged by exposure to chemicals.

Solid state NMR spectroscopy reveals the workings of 'Mother Nature's Blowtorch'

Using atom-level imaging techniques, University of Michigan researchers have revealed important structural details of an enzyme system known as "Mother Nature's blowtorch" for its role in helping the body efficiently break down many drugs and toxins.

Novel insecticidal toxins from bacteria

A light-emitting strain of bacteria and a nematode worm, which work together to prey on soil-dwelling insects, use insecticidal toxins to kill their insect hosts.

Prevalence of algatoxin in the marine environment appears to be increasing

If ingested, for example in seafood, these toxins can lead to discomfort or even illness. The algatoxin yessotoxin (YTX), which is found in both mussels and scallops in Norway, may be a potential disease risk factor in the consumption of seafood. "We don't know the long-term effects of YTX on people", says Monica Suarez Korsnes of the Norwegian School of Veterinary Science (NVH).

Bacterial toxins and perforins have a common ancestor

Human immune proteins crucial for fighting cancer, viruses and bacterial infections belong to an ancient and lethal toxin family previously only found in bacteria, Australian researchers have found.

Traffic and childhood asthma

Children who carry variations in specific genes that metabolize vehicle emissions are more susceptible to developing asthma, particularly if they live near major roadways, a study led by researchers at the University of Southern California (USC) suggests.

Exhaust fumes increase risk for asthma in genetically susceptible children

Exhaust fumes heighten the risk of asthma in children who are already genetically susceptible to respiratory disease, indicates research published ahead of print in the journal Thorax.

Clemson scientists improve longevity of fluorescent nanoparticles

Clemson University chemists have developed a method to dramatically improve the longevity of fluorescent nanoparticles that may someday help researchers track the motion of a single molecule as it travels through a living cell.

Green tea for cancer prevention

Concentrated chemicals derived from green tea dramatically boosted production of a group of key detoxification enzymes in people with low levels of these beneficial proteins, according to researchers at Arizona Cancer Center.

Potential new ways to prevent smoking-related cellular damage

In the current issue of PLoS One, researchers show how a poorly understood and previously unsuspected mechanism may be the key to understanding how life-style associated forms of oxidative stress, such as exposure to cigarette smoke, damage cells in the lungs.

New tool for use in addressing lead poisoning

Lead in goat blood might not be on the top of your shopping list, but for U.S. medical personnel who each year perform more than 2 million human blood measurements, Standard Reference Material (SRM) 955c from the National Institute of Standards and Technology (NIST) can't be beat.

Immunity in social amoeba suggests ancient beginnings

Finding an immune system in the social amoeba (Dictyostelium discoideum) is not only surprising but it also may prove a clue as to what is necessary for an organism to become multicellular, said the Baylor College of Medicine researcher who led the research that appears in the journal Science.
