Scientists identify gene for childhood neuroblastoma

US scientists have discovered genetic faults that appear to be behind the majority of inherited cases of the childhood cancer neuroblastoma.

Scientists change one mice cell into another

NEW YORK - Talk about an extreme makeover: Scientists have transformed one type of cell into another in living mice, a big step toward the goal of growing replacement tissues to treat a variety of diseases.

Alien plant threatens rare Scottish moth

A rare Scottish moth, found only on two islands in the Hebrides, could fall victim to an invasive plant that is burying its habitat.

Bush endangered species plan criticized

The Bush administration's proposal to reinterpret the Endangered Species Act is being criticized by the Ecological Society of America.

Small, sustainable fishing being undercut

University of British Columbia researchers in Canada say small fisheries are undermined by ill-conceived eco-labeling initiatives and unfair fuel subsidies.

DNA packaging feat has evolutionary basis

A human cell squeezes two metres of DNA into the space of a chromosome, 10,000 times smaller than the genetic material in it. Single-celled algae and related organisms have evolved more than one way to do this .

Presidential Elections Will Force Stem Cell Showdown

It's often hard to evaluate the competing claims made for stem cells, which -- thanks to the necessity of destroying embryos to make embryonic stem cells -- have been the scientific centerpiece of the culture wars for nearly a decade.

Despite Breakthroughs, Embryonic Stem Cells Still Needed

The transformation of pancreas cells from one type to another has been hailed as a breakthrough: until now, such tricks required of scientifically -- and sometimes ethically -- tricky stem cells.

Golden Oldie: Mr. Fish Is 27

Five years ago, Edith had a problem: Her goldfish of 25 years, Mr. Fish, had dropsy, a disease characterized by a swollen or hollow abdomen and in most cases fatal. In her last attempt to save her pet, on a whim, Edith wrote a message on GoldfishConnection asking for help.

Researcher shows proteins have controlled motions

(PhysOrg.com) -- Iowa State University researcher Robert Jernigan believes that his research shows proteins have controlled motions. Most biochemists traditionally believe proteins have many random, uncontrolled movements.

Rare Earth Elements Excite Protein Probes

Seeing what's going on inside living cells at the molecular level may reveal biological mechanisms and ultimately lead to more effective medicines. While sophisticated microscopes allow scientists to take pictures of a single molecule, capturing images of single molecules in a living cell has been particularly challenging. The molecules must be "tagged" to made visible under the microscope.

Stem Cell Therapeutics Corp. (Calgary, AB)

Stem Cell Therapeutics Corp. (Calgary, AB) announces that it has been granted U.S. patent no. 7,393,830 entitled “Prolactin induced increase in neural stem cell numbers”, and Australian patent no. 2002325711 entitled “Prolactin induced increase in neural stem cell numbers and therapeutical use thereof”. These patents cover the use of prolactin alone, as well as in combination with other therapeutics. Prolactin is used alone or with anti-inflammatories in programs to treat multiple sclerosis, and in combination with EPO to treat neurodegenerative diseases.

Study of islands reveals surprising extinction results

It's no secret that humans are having a huge impact on the life cycles of plants and animals. UC Santa Barbara's Steven D. Gaines and fellow researcher Dov Sax decided to test that theory by studying the world's far-flung islands.
