Could Bt transgenic crops have nutritionally favourable effects on insects?
Researchers from Imperial College, England have just shown in a forthcoming article in the journal Ecology Letters, that insect larvae can use an engineered toxin (Cry1Ac) as a supplementary food source. They found that toxin-resistant larvae of the Diamondback Moth developed faster and had a greater pupal weight in the presence of the toxin.... view more... (2003-03-12)
Very long term effects of Botox still unknown
The use of botulinum toxin for facial cosmetic enhancement has established its new image as a glamour drug, but its unlicensed use is increasing dramatically for certain conditions, ahead of clear scientific evidence. Although negative side effects are few, its very long term effects are still unknown, warns a neurology expert in this week’s... view more... (2002-11-20)

Contraceptive pill produced from potato toxin
Dutch researcher Patrick Vronen from Wageningen University has investigated several methods for converting toxins in high-starch potatoes into a raw material for steroid hormones used, for example, in contraceptive pills. The molecular structure of the potato toxin solanidine, which is found in high-starch potatoes, is similar to that of... view more... (2003-06-24)
Pioneering research into health benefits of beauty treatment
Pioneering medical research is going on at the University of Leicester into the use of Botulinum toxin - commonly thought of as a beauty treatment - for bladder problems. view more (2007-03-07)
Tetanus toxin found to have therapeutic properties
A team of researchers from the Department of Biochemistry and Molecular Biology and the Institute of Neuroscience at the Universitat Autònoma de Barcelona has discovered that tetanus toxin, which causes tetanus, could be extremely useful as a therapy against psychological disorders such as depression, anxiety and anorexia, and to slow... view more...

NEW LOOK ENVIRONMENT AWARD FOR ENGINEERS LAUNCHED FOR 1999
The competition, the only award to recognise the achievements of individual engineers in their work to protect and enhance the environment, is reshaped for 1999 with a totally new class structure that mirrors current environmental concerns and Government initiatives. view more (1999-03-11)
Evolution mystery: Spider venom and bacteria share same toxin
Biology researchers at Lewis & Clark College and the University of Arizona have found evidence for an ancient transfer of a toxin between ancestors of two very dissimilar organisms-spiders and a bacterium. view more (2006-02-02)
Unexpected features of anthrax toxin may lead to new types of therapies
Surprising new insights about the acid pH levels required for anthrax toxin to invade the cells of the body may help accelerate development of medications for the treatment of anthrax, a disease caused by a spore-forming bacterium. view more (2005-08-30)
Curbing C. difficile's toxin production
As if being admitted to the hospital weren't bad enough, patients, once admitted, are at higher risk of becoming infected with a "superbug" bacterium, Clostridium difficile (C. difficile). view more (2007-09-06)
Highly concentrated botulinum preparation for cosmetic injections can result in severe illness
An examination of 4 cases of botulism following cosmetic injections to the face indicates that the adults received a highly concentrated, unlicensed preparation that resulted in toxin levels up to 40 times the estimated human lethal dose. view more (2006-11-22)

Penn researchers use honeybee venom toxin to develop a new tool for studying hypertension
Researchers at the University of Pennsylvania School of Medicine have modified a honeybee venom toxin so that it can be used as a tool to study the inner workings of ion channels that control heart rate and the recycling of salt in kidneys. view more (2008-09-18)
The first gene-encoded amphibian toxin isolated
Researchers in China have discovered the first protein-based toxin in an amphibian -a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison. view more (2009-08-18)
Study helps explain why botulinum toxin is so deadly
A pilot without a map can locate an airport by first finding a nearby landmark, like a big river, and then searching for the airport. view more (2006-12-14)
Bacteria pack their own demise
Numerous pathogens contain an 'internal time bomb', a deadly mechanism that can be used against them. After years of work, VIB researchers at the Vrije Universiteit Brussel (VUB) were able to determine the structure and operating mechanism of the proteins involved. view more (2009-07-31)
Plant pathogen yields substance to fight neuroblastoma
Drug treatment of neuroblastoma, a tumor of the nervous system in children, poses major problems. Therefore, scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have been searching for substances that are suitable as a basis for developing better drugs. Now they have found a candidate: HC-toxin, which is... view more... (2008-01-18)
Ricin's Deadly Action Revealed by Glowing Probes
A new chemical probe can rapidly detect ricin, a deadly poison with no known antidote that is feared to be a potential weapon for terrorists and cannot quickly be identified with currently available tests. view more (2008-08-07)
