Professional welders risk losing their sense of smell

Researchers at the University of Pennsylvania School of Medicine have found that professional welders who work in enclosed spaces with poor ventilation may be at risk for loss of sense of smell. The study appears in Neurology .

Chlamydomonas reinhardtii genome holds clues for renewable energy, the environment and human health

University of Minnesota researchers contributed to a national effort to sequence the genome of an ancient, one-celled organism that will help advance research in a broad range of areas, from biofuels to restoring the environment to understanding a variety of human diseases.

Dual action anthrax vaccine-antitoxin combination developed

The immune response generated in rats by the new agent protects against lethal toxin exposure after only one injection, and is faster and stronger than any currently available vaccine.

Fungus genome yielding answers to protect grains, people and animals

Why a pathogen is a pathogen may be answered as scientists study the recently mapped genetic makeup of a fungus that spawns the worst cereal grains disease known and also can produce toxins potentially fatal to people and livestock.

Ozone impairs the body's immune system

According to a new study not only does air pollution exacerbate heart problems but it also impairs the body's immune system.

New test detects the presence of biogenic amines

Researchers in California are reporting development of a fast, inexpensive test suitable for home use that could help millions of people avoid those 'out of the blue' headaches that may follow consumption of certain red wines, cheese, chocolate, and other aged or fermented foods.

Inhaled ozone impairs the body's first line of defense

As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body's first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria.

Sandia develops portable microfluidic platform to detect biotoxins

Of all the threat scenarios facing emergency responders around the country, the release and spread of a dangerous biotoxin in a large public space is one of the most troubling.

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.

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.
