New study looks to define evangelicals and how they affect polling

The way the evangelical movement is defined has profound implications for where evangelicals fit into the political spectrum, according to a study by sociologists at Rice University and the University of Texas-Austin.

"In this election year, there is much debate over whether Sen. Obama can shave off enough evangelical votes to carry certain swing states, said Rice's D. Michael Lindsay, one of the researchers. "That depends a great deal on which poll you are looking at and, more importantly, how the survey defines the evangelical population."

Scientists detect cosmic 'dark flow' across billions of light years

WASHINGTON -- Using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), scientists have identified an unexpected motion in distant galaxy clusters. The cause, they suggest, is the gravitational attraction of matter that lies beyond the observable universe.

"The clusters show a small but measurable velocity that is independent of the universe's expansion and does not change as distances increase," says lead researcher Alexander Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Md. "We never expected to find anything like this."

New ways to use biomass

Alternatives to fossil fuels and natural gas as carbon sources and fuel are in demand. Biomass could play a more significant part in the future. Researchers in the USA and China have now developed a new catalyst that directly converts cellulose, the most common form of biomass, into ethylene glycol, an important intermediate product for chemical industry. As reported in the journal Angewandte Chemie, the catalyst is made of tungsten carbide and nickel on a carbon support.

Culture greatly shapes young people's drinking habits

WASHINGTON, DC, 23 September 2008 – Whether young people get drunk as a purposeful behavior or as an unintended consequence depends on what country they live in, according to new research on young people in seven countries. The research finds that young people's views on alcohol and drunkenness were influenced more by culture than by factors such as age and sex.

The research, sponsored by the International Center for Alcohol Policies (ICAP), also finds striking similarities about drinking among young people in different parts of the world including:

Is it better to stand in line or leave and come back?

If there's one thing that separates humankind from the animals, it's that human beings wait in lines. To make a deposit at the bank, to pay for groceries, even to vote -- we've all learned to queue, one behind the other. And we've learned, if not to like it, then at least to grin and bear it.

Is the salad bar safe? Produce concerns linger after summer scares

COLUMBIA, Mo. – Widespread reports had most people afraid to eat tomatoes this summer and when tomatoes were vindicated, eating peppers became a fear. A University of Missouri food safety expert says there is only so much that can be done to assure produce is safe to eat.

Controlling light with sound: new liquid camera lens as simple as water and vibration

Troy, N.Y. – New miniature image-capturing technology powered by water, sound, and surface tension could lead to smarter and lighter cameras in everything from cell phones and automobiles to autonomous robots and miniature spy planes.

Researchers at Rensselaer Polytechnic Institute have designed and tested an adaptive liquid lens that captures 250 pictures per second and requires considerably less energy to operate than competing technologies.

National survey finds information tech and business alignment a struggle for American companies

HOBOKEN, N.J. - The Society for Information Management (SIM) has released an important part of its annual survey results, reporting that IT executives continue to identify lack of IT and business alignment as the top concern for companies. Other top concerns include a deficiency in business skills training for IT professionals, and the need for greater emphasis on strategic planning in IT. HR considerations were among one-third of the top ten concerns.

New tool for 'right first time' drug manufacture

A technology which provides high quality images of the crystallisation process marks the next step towards a 'right first time' approach to drug manufacture, according to engineers at the University of Leeds.

Developed in collaboration with industrial scientists at Perdix and Malvern Instruments, the new process analytical technology (PAT) tool characterises particle shapes using a probe which collects images of the crystallization process. The tool will enable pharmaceutical companies to monitor and optimise these processes.

Carbon Disclosure Project: 'World's largest corporations seek clarity on climate change regulation'

Global corporations view climate change as a driver of risk and opportunity and have cited clear regulation as key to managing the impacts, in this year's findings from the Carbon Disclosure Project (CDP), which includes exclusive data from 1550 of the world's major companies on greenhouse gas emissions and climate change related strategies.

Research pushes back history of crop development 10,000 years

Researchers led by Dr Robin Allaby of the University of Warwick's plant research arm Warwick HRI have found evidence that genetics supports the idea that the emergence of agriculture in prehistory took much longer than originally thought.

Bats pick up rustling sounds against highway background noise

Listening for faint rustling noises made by tasty beetles on a quiet day is simple for bats hunting with their exquisitely sensitive hearing. So try imagining what it must be like trying to locate rustling treats just metres from a roaring highway. It would seem to be almost impossible to pick out a centipede's footsteps as a juggernaut hurtles past; or is it? How animals that locate their prey by sound alone cope in our increasingly noisy world puzzles Björn Siemers from the Max Planck Institute for Ornithology in Germany.

UCLA study of satellite imagery casts doubt on surge's success in Baghdad

By tracking the amount of light emitted by Baghdad neighborhoods at night, a team of UCLA geographers has uncovered fresh evidence that last year's U.S. troop surge in Iraq may not have been as effective at improving security as some U.S. officials have maintained.

BOSS: The Baryon Oscillation Spectroscopic Survey

The Sloan Digital Sky Survey (SDSS) uses a 2.5-meter telescope with a wider field of view than any other large telescope, located on a mountaintop in New Mexico called Apache Point and devoted solely to mapping the universe. We now know that some three-quarters of the universe consists of dark energy, whose very existence was unsuspected when telescope construction began in 1994 and still controversial when the first Sloan survey started in 2000.

Scientists find 'redesigned hammer' that forged evolution of pregnancy in mammals

New Haven, Conn. — Yale researchers have shown that the origin and evolution of the placenta and uterus in mammals is associated with evolutionary changes in a single regulatory protein, according to a report in Proceedings of the National Academy of Sciences.
