Animals in the oceans surrounding Antarctica are under increasing threat. Fishery management organisations and governments need to do more to eliminate illegal fishing and regulate better legal fishing in Southern Ocean and adjacent areas according to Professor John Croxall speaking today (17 Feb) at a special symposium – Conserving Migratory Marine Organisms: Protecting animals with ocean-sized habitats organised by the American Association for the Advancement of Science (AAAS).

A cell type with the potential for making the four major types of human tissue has been found in the stomach and small intestine by a Medical College of Georgia researcher.

These VENT cells have been found in addition to the three sources of cells typically associated with gastrointestinal development, says Dr. Paul Sohal, MCG developmental biologist, who first identified these cells nearly a decade ago.

Identification of VENT – ventrally emigrating neural tube – cells within the

Researchers at the University of Pittsburgh Cancer Institute (UPCI), in collaboration with Johns Hopkins University School of Medicine have found that a recently discovered gene plays an essential role in mediating apoptosis, or cell death, in colorectal cancer cells. The results are published in the Feb. 18 issue of Proceedings of the National Academy of Sciences.

The gene, PUMA, or p53 up-regulated modulator of apoptosis, is controlled by p53 – a tumor-suppressing gene that prevents norma

While the vision-impaired Hubble Space Telescope needed optical doctoring from shuttle astronauts, vision researchers back on Earth were wondering if the human eye was clever enough to fix itself.

Now a neurobiology study at Cornell University suggests that internal parts of the eye indeed can compensate for less-than-perfect conditions in other parts — either developmentally (during the lifetime of one individual) or genetically (over many generations).

Results of the study, “I

Broad implications seen for treating Alzheimer’s and other human diseases

By teaching fruit flies to avoid an odor and isolating mutant flies that can’t remember their lessons, researchers at Cold Spring Harbor Laboratory in New York have identified dozens of genes required for long-term memory.

In the same study, using DNA chip technology, the scientists identified another large group of candidate memory genes that are either switched on or off in the fly brain during memo

Gaiker y Santa Ana de Bolueta Abrasión, S. A., have developed a novel, rapid and efficient method to reduce abrasion in industrial parts.

The considerable wear suffered by industrial parts and equipment and by extracting tools that come into contact with abrasive materials forces companies to make periodic maintenance breaks in normal activity, thus causing considerable losses in time and money.

Santa Ana de Bolueta Abrasión, S. A., together with Gaiker, have developed a novel metho
