New study suggests link between environmental toxins and early onset puberty in girls
Although scientists have speculated over the negative effects of environmental toxins for years, new data suggest that certain environmental toxins may disrupt the normal growth and hormonal development of girls.   view more (2008-02-07)

Detecting poisons in nectar is an odour-ous task for honeybees
Though many spring flowers have bright advertisements offering sweet rewards to honeybees, some common flowers have not-so-sweet or even toxic nectars.   view more (2007-04-02)

Prevention is better than cure
The Institute of Biology is calling on the International Community to strengthen the Biological and Toxins Weapons Convention. In a statement to be presented to the Fifth Review Conference of the Parties to the Biological and Toxins Weapons Convention (BTWC), the Institute warns that the current... view more (2001-11-20)

Molecular structure reveals how botulinum toxin attaches to nerve cells
Botulism is a life-threatening disease caused by exposure to botulinum neurotoxins, which are among the most potent toxins known. These neurotoxins are produced by Clostridium botulinum, a bacterium found in soil and food.   view more (2006-12-14)

New service to help monitor toxic species in marine waters
University of Liverpool scientists have launched a new website to help environmental agencies and marine industries identify harmful organisms in UK coastal waters.   view more (2006-01-25)

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)

Success for fishy scientist
Scallops, oysters and mussels - the best of fare Scotland`s kitchens have resulted in a top Parisian award for a researcher from the University of Dundee. Matthew Gubbins is not a chef but a scientific expert on toxicity in shellfish. Matthew (26) has scooped the Daniel Jouvance award for his work... view more (2002-07-18)

'Red tide toxins' leave beachgoers breathless
The ecological phenomenon, known as Florida red tide, can be harmful for people with asthma. Florida red tides, an annual event in areas along the Gulf of Mexico, are blooms of the ocean organism, Karenia brevis (K brevis), that are concentrated along shorelines and produce highly potent... view more (2007-01-09)

Structures of marine toxins provide insight into their effectiveness as cancer drugs
Vibrantly colored creatures from the depths of the South Pacific Ocean harbor toxins that potentially can act as powerful anti-cancer drugs, according to research findings from University of Wisconsin-Madison biochemists and their Italian colleagues.   view more (2005-09-27)

Nonvenomous Asian snakes 'borrow' defensive poison from toxic toads
Most snakes are born with poisonous bites they use for defense. But what can non-poisonous snakes do to ward off predators?   view more (2007-01-31)

Scientists discover possible link between oxidative stress and non-hereditary degenerative disease
The irreversible neurological degeneration associated with Parkinson's and Alzheimer's diseases may be the consequence of oxidative stress-the imbalance of antioxidants and pro-oxidants in cells.   view more (2006-04-28)

Vaccine could cut complications after surgery
A vaccine has been developed, which could prevent inflammation and illness caused by certain bacterial infections following major surgery, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick. Dr Elliott... view more (2002-04-03)

What Makes The Scorpion`S Sting Deadly Poisonous?
Even the scorpion`s exterior warns that this is a dangerous animal. And it proves to be true, as nothing good comes out when small animals and even human beings meet with this arthropod species: its sting causes a sharp pain, some tropical scorpion`s sting is often fatal for the victim. The... view more (2002-03-15)

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)

Gene-expression profiling of the effects of liver toxins
Gene-expression data from liver tissue or whole blood can be used to classify histopathologic differences in the effects of hepatotoxins. It is hoped that these findings, published in BioMed Central's open access journal, Genome Biology, will lead to a more precise way of defining the potential... view more (2008-06-20)

Advances in C. difficile research
New research into the toxins, virulence, spread and prevention of the superbug Clostridium difficile is reported in the June special issue of the Journal of Medical Microbiology. These findings will play a crucial role in providing us with ammunition in the fight against a sometimes deadly pathogen.   view more (2008-06-02)

New designer toxins kill Bt-resistant insect pests
A new way to combat resistant pests stems from discovering how the widely used natural insecticide Bt kills insects.   view more (2007-11-02)

Bird fall-out measures radioactive fall-out
Jim Clapp (University of Ulster) will reveal how bird droppings can be used to measure radioactive fall-out in the environment. Solid urate spheres found in bird excretions can be screened for man-made pollutants such as radioactive caesium, providing a new non-invasive way to monitor the... view more (2004-03-30)

Plastics suspect in lobster illness
The search for what causes a debilitating shell disease affecting lobsters from Long Island Sound to Maine has led one Marine Biological Laboratory (MBL) visiting scientist to suspect environmental alkyphenols, formed primarily by the breakdown of hard transparent plastics.   view more (2008-08-15)

Children's diet not the main cause of ADHD
Food may not be the major cause of hyperactivity in children. Genetics, brain function and parental actions such as smoking may be just as important.   view more (2008-05-30)

Study reveals molecular basis of botulism toxin's deadly activity
In the study, the scientists reveal the mysterious structural basis of the remarkably strong interaction that botulinum toxins form with nerve cells, a union so robust that a single toxin molecule can completely incapacitate a nerve cell.   view more (2006-12-18)

Mouse genome will help identify causes of environmental disease
Research on the DNA of 15 mouse strains commonly used in biomedical studies is expected to help scientists determine the genes related to susceptibility to environmental disease.   view more (2007-07-30)

Researchers discover how infectious bacteria can switch species
Scientists from the Universities of Bath and Exeter have developed a rapid new way of checking for toxic genes in disease-causing bacteria which infect insects and humans.   view more (2008-10-09)

Doubling of deaths from liver cancer in 30 years
Deaths from liver cancer have almost doubled in the past 30 years, shows research in Gut. A relatively rare type of liver cancer arising from the bile ducts - intrahepatic cholangiocarcinoma - accounts for virtually all of the increase. The research team analysed deaths coded by liver tumour... view more (2001-05-16)

Toxic shock: immune system's anthrax link
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.   view more (2007-08-24)
