University of Michigan paleontologist Philip D. Gingerich and colleagues at the Egyptian Environmental Affairs Agency (EEAA) announced April 10 the successful excavation of an unusually complete and well-preserved skeleton of the 40 million-year-old fossil whale Basilosaurus isis.

The new skeleton is 18 meters (50 feet) long and was found in Wadi Hitan in the Western Sahara of Egypt. The first Basilosaurus fossil was found in 1905 but no full skeleton has been discovered until now.

UTMB scientists offer strongest evidence yet that infectious misformed proteins cause mad cow disease and other mysterious brain disorders

Researchers at the University of Texas Medical Branch at Galveston (UTMB) have produced the strongest proof yet that the mysterious and devastating brain diseases known as "transmissible spongiform encephalopathies" (TSEs) are transmitted by an infectious agent composed only of a malformed protein, and not a virus. TSEs, which can afflict both human beings and animals, include mad cow disease, new-variant Creutzfeldt-Jakob Syndrome, scrapie, kuru and chronic wasting disease.

In a genomics milestone, an international consortium of researchers has for the first time lifted the veil from a fungal plant pathogen by sequencing the genome – or set of all genes – of the most destructive enemy of rice: Magnaporthe grisea, the fungus that causes rice blast disease.

Howard Hughes Medical Institute researchers chiseling away at the problem of antibiotic resistance now have a detailed explanation of how the drugs' main cellular target in bacteria evolves to become resistant to some of these medications. The findings are already leading to new experimental antibiotics that are being engineered to circumvent resistance, which is a major worldwide health problem.

As the world prepared to observe Earth Day, World Wildlife Fund and its partners in the International Smart Gear Competition announced three new winning solutions to prevent the accidental maiming and killing of marine mammals, juvenile fish, and sea turtles that become ensnared by fishing nets and longlines--a problem known as bycatch--while also improving the efficiency of commercial fishing.

The power of a new technique to map connections among nerve cells in the brain has a UT Southwestern Medical Center scientist dreaming of solving the mysteries of sleep.

By tracking which nerve cells in the mouse brain stimulate others, researchers in Japan and at UT Southwestern found that a type of neuron responsible for keeping animals awake receives inhibitory signals from neurons active only during sleep, as well as reinforcing, positive signals from nerve cells that are very active during wakefulness.

The Food and Drug Administration (FDA) today announced a series of important changes pertaining to the marketing of the non-steroidal anti-inflammatory class of drugs, including COX-2 selective and prescription and non-prescription (over-the-counter (OTC)) non-selective NSAID medications. A list of these products is available on the Internet at http://www.fda.gov/cder/drug/infopage/cox2/default.htm.

Cancer patients may one day benefit from treatment with mixtures of customized antibodies. In a study published recently in the Proceedings of the National Academy of Sciences (USA), a team of Weizmann Institute scientists have demonstrated how the right combination might form a web that destroys the cancer cell's communication network, ultimately demobilizing the cell.
