Fighting to keep Darwin in the classroom

...m," and, most recently, "intelligent design." The battle to keep religiously based explanations of the history of life—especially human life—out of the science curriculum continues unabated. And though a number of educational institutions and organizations have had notable success in combating intelligent...

Breakthrough vaccine to treat chemo-resistant ovarian cancer

...umber one priority is to help our patients win the battle against cancer," said Dr. Edgar Staren, Chief Medical Officer of Cancer Treatment Centers of America. "This vaccine therapy represents a promising new chapter in the fight against this devastating disease and brings hope to women everywhere." The ...

Scientists find genes involved in the battle between Hessian flies and wheat

Wheat has ways to battle the tiny, red wormlike insects that nibble on the plant's leaves and can destroy crops worldwide, but the Hessian fly larvae that survive eventually evolve methods to overcome plant defenses. Purdue University and USDA-Agriculture Research Service s...

LIAI scientists make important finding on cytomegalovirus transmission

...us building the body’s ability to more effectively battle the virus. "We used this approach to tip the balance in favor of the T cells that would reduce the virus," he said. The scientists got a stronger result by blocking the IL-10 receptor. "It significantly reduced the virus load in all the animals ...

Corals -- More complex than you?

..., we will gain new insights which will help in the battle against human disease, he adds. The richness of the coral genome ?unexpectedly loaded with genes, many of which were thought to have evolved much later?is also casting new light on evolution. It appears that all animals lose genes during evolut...

Amphibians in losing race with environmental change

...ese challenges, amphibians appear to be losing the battle ?of 5,743 known species of amphibians on Earth, 43 percent are in decline, 32 percent are threatened and 168 species are believed extinct. The impacts of changes are far more pervasive on amphibians than many other vertebrates, such as birds or mamma...

Technique monitors thousands of molecules simultaneously

... the polarity of things "The chip is an ongoing battle between active reagent and inactive reagent," Moeller said. "The active reagent is fine ?it does the chemistry I want it to do ?but as soon as it gets away from the turned-on electrode the reaction that inactivates it needs to take over." With an o...

Ancient retrovirus sheds light on modern pandemic

...retrovirus, or PtERV1. "This ancient virus is a battle that humans have already won. Humans are not susceptible to it and have probably been resistant throughout millennia," said senior author Michael Emerman, Ph.D., a member of the Human Biology and Basic Sciences divisions at the Hutchinson Center. "Ho...

Electric fish conduct electric duets in aquatic courtship

Cornell researchers have discovered that in the battle of the sexes, African electric fish couples not only use specific electrical signals to court but also engage in a sort of dueling "electric duet." The study is the first to compare electrical and behavioral displays in breeding and nonbreeding Brie...

Potent possibilities for parasite attack

...ved in interacting with the human host - where the battle between parasite and patient is fought and where rapid response is important to both. Remarkably, L. braziliensis, the most ancient Leishmania species sequenced, contains genes that could provide a working pathway for RNAi, an emerging mechanism f...

Progress toward an antitumor vaccine

... body to use its own weapon, the immune system, to battle cancer" In principle, by the same means used against infectious diseases: immunization. The production of a selective vaccine is not a trivial task, however. A team led by Horst Kunst at the University of Mainz has now found a way to bind a molecule ...

Newly discovered antibody may be body's natural defense against Alzheimer's

In an important advance in the battle against Alzheimer's disease, physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center have identified naturally occurring antibodies in human blood that may help to defend against this form of dementia as well as other neuro...

Breakthrough developments in rheumatoid arthritis reported

..., immune cells that are normally called on to wage battle against infection. In autoimmune diseases like rheumatoid arthritis, PTPN22 appears to put people at higher risk of a wayward T-cell response. The group has since gone on to use modern genetic methods to search for single nucleotide polymorphism...

CSIRO scientists join fight to save 'Tassie devil'

CSIRO scientists have joined the battle to save Australia’s iconic Tasmanian devils from the deadly cancer currently devastating devil populations. Researchers from CSIRO’s Livestock Industries’ Australian Animal Health Laboratory (AAHL), Textiles and Fibre Technology and Land and Water, ...
