Researchers investigate new suspect in West Nile deaths of pelicans
(AP) -- Radio advertisers who for years complained about the low-tech way of tracking listeners are getting what they asked for and more: Electronic ratings are delivering more accurate counts, but are also upending basic assumptions about the industry.
Researchers use remote sensing technology to go back in time on the Ethiopian Plateau
Veterinary entomologist Greg Johnson of Montana State University said earlier this year that he considered the possibility that lice were transmitting West Nile virus to pelicans. He became suspicious after collecting very few mosquitoes in 2006, but seeing pelicans continue to die at a high rate. Johnson discovered previously that the Culex tarsalis mosquito is the primary carrier of West Nile...
Former Astronaut's Son Buys Space Ticket
The cliffs that rise above the Blue Nile contain 750 million years of exposed geologic history. But it`s what`s happened in the past 6 million years that intrigues Dr. Mohamed Abdelsalam, an associate professor of geology at the University of Missouri-Rolla, and his research colleagues.
Neuroscientists connect neural activity and blood flow in new brain stimulation technique
(AP) -- The millionaire son of a retired astronaut is about to follow his father into orbit, after buying a seat on a Russian rocket.
NASA's Ion Engine Breaks Performance Record
Neuroscientists at the University of California, Berkeley, have for the first time measured the electrical activity of nerve cells and correlated it to changes in blood flow in response to transcranial magnetic stimulation (TMS), a noninvasive method to stimulate neurons in the brain.
Playing video games reduces sex differences in spatial skills
An ion engine prototype developed at NASA's Glenn Research Center has now accumulated more than 12,000 hours of operation and processed over 245 kilograms of xenon, setting a record for most propellant throughput ever demonstrated by an ion engine.
Women have a poorer quality of life after a stroke than men, study reveals
University of Toronto researchers have discovered that differences between men and women on some tasks that require spatial skills are largely eliminated after both groups play a video game for only a few hours. The research, to be published in the October issue of Psychological Science, suggests that a new approach involving action video games can be used to improve spatial skills that are...
Drug Trials Go Unwatched, Study Says
A new University of Nottingham study has found that women have a poorer quality of life than men following a stroke.
Microsoft Excel Fails Math Test

'Dead time' limits quantum cryptography speeds
(AP) -- Microsoft Corp.'s Excel 2007 spreadsheet program is going to have to relearn part of its multiplication table.
Measurements from the edge: magnetic properties of thin films
Quantum cryptography is potentially the most secure method of sending encrypted information, but does it have a speed limit" According to a new paper by researchers at the National Institute of Standards and Technology and the Joint Quantum Institute, technological and security issues will stall maximum transmission rates at levels comparable to that of a single broadband connection, such as a...
Improving doctor-patient communication yields significant health benefits
Materials researchers at the National Institute of Standards and Technology, together with colleagues from IBM and the Massachusetts Institute of Technology, have pushed the measurement of thin films to the edgeliterallyto produce the first data on how the edges of metallic thin films contribute to their magnetic properties. Their results may impact the design of future nanoscale electronics.
Surprise in the organic orchard -- a healthier worm in the apple
A UCSF research team has developed a simple tool that can improve the effectiveness of communication between doctors and patients about prescribed medications and result in dramatic improvements in health and safety.
Recovery from acid rain 'much slower than expected'
Insects can catch more than a cold from certain viruses. Some viruses can be lethal to pest species - turning their insides to soup - without harming beneficial insects or other organisms. Hence they are used as an environmentally friendly means of biological crop protection worldwide. The proverbial worm in the apple, the codling moth caterpillar, has been controlled in European orchards for...
Mysterious energy burst stuns astronomers
Acid rain was one of the world`s worst pollution problems of the 1970s and 1980s, affecting large areas of upland Britain, as well as Europe and North America.
Water forms floating 'bridge' when exposed to high voltage
Astronomers studying archival data from an Australian radio telescope have discovered a powerful, short-lived burst of radio waves that they say indicates an entirely new type of astronomical phenomenon.
Babies raised in bilingual homes learn new words differently than infants learning one language
While it's one of the most important and abundant chemical compounds on Earth, water is still a puzzle to scientists. Much research has been done to uncover the structure of water beyond the H2 O scale, which is thought to be responsible for many of water`s unique properties. However, the nature of this structure, governed by hydrogen bonds, is currently unknown.
Congress OKs Expanded Kids' Health Care
Infants who are raised in bilingual homes learned two similar-sounding words in a laboratory task at a later age than babies who are raised in homes where only one language is spoken.
DNA damage response confers a barrier for viral tumorigenesis
(AP) -- Setting up a veto fight with President Bush while handing Democrats another campaign issue, Congress passed legislation to expand a popular children's health program.
Gamers Spend About $170M on 'Halo 3'
Kaposi`s sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi`s sarcoma (KS). KSHV infection is endemic in sub-Saharan Africa where KS is nowadays the most common malignancy, due to widespread infection with KSHV and human immunodeficiency virus (HIV). Importantly, KS also occurs in HIV-negative individuals. Researchers at the University of Helsinki, Finland, have...
