Research points to a possible way to design anthrax toxin molecules that selectively attack tumor cells

Scientists have determined a three-dimensional (3-D) molecular image of how anthrax toxin enters human cells, giving scientists more potential targets for blocking the toxin, the lethal part of anthrax bacteria.

Eleven states oppose mercury emissions proposal

Attorneys General and top environmental officials from eleven states joined today in formally opposing a U.S. Environmental Protection Agency proposal that would allow coal-fired power plants to escape Clean Air Act mandates that require them to reduce mercury emissions that threaten public health – particularly the health of children and pregnant women.

Xenobiotic gets patent approval for toxin detection

XDS consultant (and former XDS laboratory director) Michael Chu and President George Clark combined their research skills to develop a rapid and relatively inexpensive methodology to quantify TEQs (Toxic Equivalence -- measures of toxicity adopted by the World Health Organization) for individual toxic chemical groups.

Significance of the discovery of anthrax toxin genes in a naturally occurring microbe other than Bacillus anthracis

Dr. Fraser discusses, for the first time, the significance of the discovery of anthrax toxin genes in a naturally occurring microbe other than Bacillus anthracis, the bacterium that causes anthrax.

Project aimed at eliminating anthrax as a potential weapon for terrorists

La Trobe University scientists are using their own unique peptide 'library' containing a thousand million molecular sequences in a project aimed at eliminating anthrax as a potential weapon for terrorists.

Australian scientists have developed a tool that acts as a pregnancy test for the detection of anthrax

Once a deadly disease associated with animals, anthrax is now used as a bioterrorist weapon. While infection can be controlled with antibiotics, in a bioterrorism attack people will not know they have been infected until symptoms develop, at which stage drugs are useless.

Over-the-counter cream protects against jellyfish stings

Two dozen volunteers bravely exposed their arms to jellyfish tentacles as part of a new Stanford University School of Medicine study to test a topical, over-the-counter cream designed to protect against stinging nettles. Fortunately for the volunteers, the cream appeared to be relatively effective.

Scientists have identified a compound that halts the activity of a deadly toxin called anthrax

University of Chicago scientists have identified a compound that halts the activity of a deadly toxin called anthrax lethal factor in laboratory tests. Nature Biotechnology will publish the findings online on May 16 and in the June issue of the journal's print edition.

New device lab-on-a-chip sensor to detect milk contamination

Whitaker investigator David Beebe, Ph.D., of the University of Wisconsin-Madison has developed a process to make on-demand, miniature sensors for a wide variety of poisons, including naturally occurring contaminants and intentionally introduced toxins.

Botox shows promise as an alternative treatment for benign prostatic hyperplasia

Injections of botulinum toxin A (botox) into the prostate are a promising alternative treatment for the millions of men who have benign prostatic hyperplasia (BPH), a condition commonly referred to as enlarged prostate, according to a study conducted by the University of Pittsburgh School of Medicine and Chang Gung Memorial Hospital in Taiwan.

Scientists closer to a potential vaccine or treatment for botulism

By deciphering the near atomic-level structure of the catalytic domain of botulinum toxin type E — one of seven neurotoxins that cause botulism, a disease that paralyzes victims by blocking nerve cells’ ability to communicate — scientists at the U.S. Department of Energy’s Brookhaven National Laboratory are one step closer to a potential vaccine or treatment.

Botox helps children with cerebral palsy

Botox, or botulinum toxin, offers a new, non-surgical option for improving the upper extremity function of children with cerebral palsy (CP), report researchers from Wake Forest University Baptist Medical Center. L. Andrew Koman, M.D., orthopedic surgeon at Brenner Children’s Hospital, and his team recently completed a study using Botox to treat muscle spasticity of the arm and hand in children with CP.

New use of Botox helps voice disorders

An injection that’s best known for smoothing wrinkles also helps restore the voices — and the confidence — of people with a voice disorder caused by spasms in their vocal cord muscles, a new University of Michigan study finds.

Research into link between oceans and human health

The National Science Foundation (NSF) and the National Institute of Environmental Health Sciences (NIEHS), one of the National Institutes of Health, have announced funding for four joint Centers for Oceans and Human Health (COHH). The centers will be located at the University of Washington, the University of Hawaii, the Woods Hole Oceanographic Institution in Massachusetts, and the University of Miami.

New research may help prevent anthrax, bubonic plague and typhoid fever

The mechanism used by the bacteria that cause anthrax, bubonic plague and typhoid fever to avoid detection and destruction by the body’s normal immune response, leading to life-threatening bacterial infections, has been identified by researchers at the University of California, San Diego (UCSD) School of Medicine.
