- Cigarette after Valentine snuggle deadlier for some
02-13-2008 · EurekAlert!
The proverbial cigarette after a Valentine's Day snuggle can prematurely end a love affair, as new evidence emerges that a common defect in a gene significantly increases a smoker's risk of an early heart attack. Researchers say that as much as 60 to 70 percent of the population has a gene defect that delivers a one-two punch to smokers; heavy smokers with this common gene variant experienced a heart attack around the age of 52.

- Genetic technology reveals how poisonous mushrooms cook up toxins
11-12-2007 · EurekAlert!
Scientists have identified genes that produce the poison of the death cap mushroom -- a unique pathway previously unknown in fungi.Reported in today's Proceedings of the National Academy of Sciences. The work not only solves a mystery of how some mushrooms make the toxin -- but also sheds light on the underlying biochemical machinery. It might be possible one day to harness the mushroom genes to make novel chemicals that would be useful as new drugs.

- Bacterial response to oxidation studied as toxin barometer
03-26-2007 · EurekAlert!
Many environmental toxins in water, such as pesticides, heavy metals, and PCBs, kill through oxidative stress mechanisms. Gram negative heterotrophic bacteria react in a way that may make them useful as biosensors.

09-03-2007 · EurekAlert!
Arthritis of the knee may be the first sign of a type of lung cancer that is hard to treat in heavy smokers, suggests research published ahead of print in the Annals of the Rheumatic Diseases. The researchers reviewed the case notes of all patients with rheumatic disorders, diagnosed at one tertiary referral centre over six years.

- Brain scans reveal cause of smokers' cravings
03-19-2007 · EurekAlert!
Within the mind of every smoker trying to quit rages a battle between the higher-order functions of the brain wanting to break the habit and the lower-order functions screaming for another cigarette, say researchers at Duke University Medical Center. More often than not, that cigarette gets lit.

- Fishing for alternatives
03-31-2007 · EurekAlert!
Cultured fish cell lines and organs such as gills, heart, liver and intestines are being used to investigate the effects of toxins on fish such as freshwater trout and carp in a move to cut down the number of experiments carried out on live fish. Fish Biologists will be presenting new culture methods to help replace the use of live fish for safety testing of chemicals in line with a European Commission directive to replace the use of animals in ecotoxicology.

In a Lowell, Mass., cemetery on Memorial Day 1868, a photograph captured mourners in heavy winter clothing gathered under leafless trees near the graves of two brothers killed in the Civil War. At the same spot on Memorial Day 2005, cemetery visitors wore light spring clothes. The trees were in full flower.

- Snake venoms share similar ingredients
12-19-2007 · EurekAlert!
Venoms from different snake families may have many deadly ingredients in common, more than was previously thought. A study published in the online open access journal BMC Molecular Biology has unexpectedly discovered three-finger toxins in a subspecies of the Massasauga Rattlesnake, as well as evidence for a novel toxin genes resulting from gene fusion.
