3D TV, Without the Glasses
If you're thinking about buying a 3D TV, you might want to wait a while. Researchers have developed new 3D technology that doesn't need any special glasses to work its magic. The new technology could advance the development of 3D on mobile devices, too.
Bioethics Panel Gives Yellow Light to Anthrax Vaccine Trial in Children
A U.S. bioethics committee has said that the country may consider testing the anthrax vaccine in children. The panel advises that the vaccine be tested in progressively younger age groups and includes the caveat (警告) that testing should only take place if risks are "minimal."
Evolution via Roadkill
We usually think of evolution happening over thousands or millions of years, but it can be surprisingly speedy—literally. In just 3 decades, highway-dwelling swallows (燕子)have evolved shorter wingspans (翼展) to better dodgeoncoming cars.
Patients Should Get DNA Information, Report Recommends
Would you want to know if you were at risk for cancer? What about a fatal heart condition? A group of genetics experts, along with the influential American College of Medical Genetics and Genomics, have recommended that anyone whose genome is sequenced for any medical reason must be told about their genetic susceptibility to serious health problems, regardless of whether they want to know.
Congress Completes Work on 2013 Spending Bill
This week, the U.S. Congress passed a bill to fund the government until the end of the fiscal(财政的) year, and research agencies now know how much to spend in 2013. The so-called continuing resolution retains the sequester and its $85 billion cut in discretionary spending. The bill throws NASA's planetary programs a lifeline and gives the National Science Foundation a bit of a boost, but the National Institutes of Health's funding stays flat at 2012 levels—bad news for biomedical research.
Making Moonshine Safe to Drink
Home-brew drinkers in developing countries often risk blindness or even death from methanol poisoning when they drink. Now, scientists have made a reusable wireless chip that can analyze a drink's methanol content and warn users of any danger. In 2 years, they hope to develop a product that can send results directly to a cell phone.
