Chop off a salamander’s leg and a brand new one will sprout in no time. But most animals have lost the ability to replace missing limbs. Now, a research team at the Salk Institute for Biological Studies has been able to regenerate a wing in a chick embryo — a species not known to be able to regrow limbs — suggesting that the potential for such regeneration exists innately in all vertebrates, including humans.
Brain and behavior relationships may have changed in a profound way as larger, more complex insect societies evolved from smaller, simpler ones, according to a new study.
Recharging your laptop computer — and also your cell phone and a variety of other gadgets — might one day be doable in the same convenient way many people now surf the Web: wirelessly. Marin Soljac?ic? of the Massachusetts Institute of Technology will present research by himself and his colleagues Aristeidis Karalis and John Joannopoulos on the physics of electromagnetic fields, showing how wireless energy could power future gadgets. The MIT team is also working on demonstrating the technology in practice. The work will be described on Tuesday, November 14 in San Francisco, at the 2006 American Institute of Physics Industrial Physics Forum (IPF), which will be co-located with the Nanotechnology Topical Conference at the AVS 53rd International Symposium & Exhibition at the Moscone Center West.
A geologist at Washington University in St. Louis and his collaborator at Oxford University have interpreted data that Lewis and Clark collected during their famous expedition and found that the Missouri River has markedly narrowed and its water levels have become more variable over the past two hundred years.
Almost half of newly diagnosed breast cancer patients are found to have clinically significant emotional distress or symptoms of psychiatric disorders before treatment is begun, according to a new study published in the December 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society.
George Washington’s favorite foods were ice cream and fish. Abraham Lincoln enjoyed fruit salad, cheese and crackers. John F. Kennedy loved New England Clam Chowder, and George W. Bush is a big fan of Mexican food.
Just as clouds block the sun, they interfere with laser communications systems, but Penn State researchers are using a combination of computational methods to find the silver lining and punch through the clouds.
University of Cincinnati (UC) environmental health researchers have determined that firefighters are significantly more likely to develop four different types of cancer than workers in other fields. Their findings suggest that the protective equipment firefighters have used in the past didn’t do a good job in protecting them against cancer-causing agents they encounter in their profession, the researchers say.
Researchers investigating ways of prompting the immune system to recognise and kill tumour cells have found that a drug containing parts of the diptheria toxin appears to work well in patients with advanced melanoma, according to research presented at the 18th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics on Thursday.
A new study led by a UC Irvine economist debunks a popular argument against urban sprawl — that living farther from neighbors decreases social interaction. In fact, the data shows that suburban living is better for one’s social life.
