  • Three to share 2010 Shaw Prize in astronomy

    Updated: 2010-05-28 14:17:51
    Baltimore Sun: Three recipients will share the $1 million Shaw Prize in astronomy this year: Charles L. Bennett of Johns Hopkins University and Lyman A. Page Jr and David N. Spergel of Princeton University. From their work with the Wilkinson Microwave Anisotropy Probe experiment, they determined that the universe is 13.7 billion years old and that the type of matter that has been observed on Earth constitutes less than 5% of all matter in the universe—dark matter and dark energy make up the other 95%.

  • How effective is the screening of airline passengers?

    Updated: 2010-05-27 14:08:42
    Nature: Future Attribute Screening Technology (FAST) is an experimental program for assessing airline passengers and others for the intent to cause harm. The program, which is being funded by the US Department of Homeland Security, relies on remote sensors that can measure heart rate, face temperature, and other supposedly outward indications of "malintent." In a news feature, Nature's Sharon Weinberger examines whether these and other methods are effective.

Although not the smallest ever created , it is embedded in a single silicon crystal and is 10 times smaller than those used in contemporary computers . The ongoing goal of computer hardware development has been to make machines that are faster , cheaper , and able to

  • Apple surpasses Microsoft as world's most valuable tech company

    Updated: 2010-05-27 14:08:19
    New York Times: On Wednesday this week, for the first time in the two companies' history, Apple Inc's total value on NASDAQ overtook Microsoft Corp's. Apple is now the world's most valuable publicly traded tech company. Among US companies of any kind, only Exxon Mobil Corp is now worth more. Apple's recent success is attributed to its introduction of a series of innovative consumer products, starting with the iPod (2001) and followed by the iPhone (2007) and iPad (2010). Microsoft, however, is currently more profitable than its rival.

    Nature: Nuclear reactors around the world produce highly enriched uranium for civilian research. Compared with the HEU in nuclear arsenals, the total amount of civilian HEU is modest (about 100 tons), yet not so modest that its proliferation implications can be discounted. Pablo Adelfang, the head of reactor research at the International Atomic Energy Agency, discussed the danger recently with Nature's Declan Butler.
