Visual assistance for cosmic blind spots
A bit of imagination on the part of a measuring instrument wouldn't be a bad thing. It could help to add data from areas where the instrument is unable to measure.   view more (2009-11-24)

Just like old times: Generating RNA molecules in water
A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors.   view more (2009-11-23)

Research challenges for understanding landscape changes identified
Nine research challenges and four research initiatives that are poised to advance the study of how Earth's landscapes change were unveiled today in a new report by the National Research Council.   view more (2009-11-19)

Rosetta bound for outer Solar System after final Earth swingby
This morning, mission controllers confirmed that ESA's comet chaser Rosetta had swung by Earth at 8:45 CET as planned, skimming past our planet to pick up a gravitational boost for an epic journey to rendezvous with comet 67P/Churyumov-Gerasimenko in 2014.   view more (2009-11-16)

ESA spacecraft may help unravel cosmic mystery
When Europe's comet chaser Rosetta swings by Earth tomorrow for a critical gravity assist, tracking data will be collected to precisely measure the satellite's change in orbital energy. The results could help unravel a cosmic mystery that has stumped scientists for two decades.   view more (2009-11-13)

Teens less likely to wash hands when cooking, more likely to cross-contaminate raw food than adults
A Kansas State University study has shown that when preparing frozen foods, adolescents are less likely than adults to wash their hands and are more susceptible to cross-contaminating raw foods while cooking.   view more (2009-11-12)

A bubbling ball of gas
The Sun is a bubbling mass. Packages of gas rise and sink, lending the sun its grainy surface structure, its granulation. Dark spots appear and disappear, clouds of matter dart up - and behind the whole thing are the magnetic fields, the engines of it all.   view more (2009-11-12)

A Lightning Strike in Africa Helps Take the Pulse of the Sun
Sunspots, which rotate around the sun's surface, tell us a great deal about our own planet. Scientists rely on them, for instance, to measure the sun's rotation or to prepare long-range forecasts of the Earth's health.   view more (2009-11-12)

Theory about long and short-term memory questioned by UCL scientists
The long-held theory that our brains use different mechanisms for forming long-term and short-term memories has been challenged by new research from UCL, published today in PNAS.   view more (2009-11-10)

For young boys with cancer, testicular tissue banking may be option to preserve fertility
For parents of children with cancer, the hopeful news is that pediatric survival rates have steadily improved for decades. Among the bad news-treatments that enable survival often cause infertility.   view more (2009-11-10)

Computer predicts reactions between molecules and surfaces, with 'chemical precision'
Good news for heterogeneous catalysis and the hydrogen economy: computers can now be used to make accurate predictions of the reactions of (hydrogen) molecules with surfaces. An international team of researchers, headed by Leiden theoretical chemist Geert-Jan Kroes, published on this subject this week in the journal Science.    view more (2009-11-09)

Follow Rosetta's final Earth boost
ESA's comet chaser Rosetta will swing by Earth for the last time on 13 November to pick up energy and begin the final leg of its 10-year journey to comet 67P/Churyumov-Gerasimenko. ESA's European Space Operations Centre will host a media briefing on that day.   view more (2009-11-05)

Texas A&M prof to predict weather on Mars
Is there such a thing as "weather" on Mars? There are some doubts, considering the planet's atmosphere is only 1 percent as dense as that of the Earth.   view more (2009-11-05)

New theory on fairness in economics targets CEO pay
Chief executives in 35 of the top Fortune 500 companies were overpaid by about 129 times their "ideal salaries" in 2008, according to a new type of theoretical analysis proposed by a Purdue University researcher to determine fair CEO compensation.    view more (2009-11-04)

Precise picture of early Universe supports 'dark matter' theory

VERITAS telescopes help solve 100-year-old mystery: The origin of cosmic rays
Nearly 100 years ago, scientists detected the first signs of cosmic rays - subatomic particles (mostly protons) that zip through space at nearly the speed of light.   view more (2009-11-03)

'Ultra-primitive' particles found in comet dust
Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution.   view more (2009-11-03)

There's a speed limit to the pace of evolution, Penn biologists say
Researchers at the University of Pennsylvania have developed a theoretical model that informs the understanding of evolution and determines how quickly an organism will evolve using a catalogue of "evolutionary speed limits."   view more (2009-11-03)

New dinosaur species from Montana
A husband and wife team of American paleontologists has discovered a new species of dinosaur that lived 112 million years ago during the early Cretaceous of central Montana.   view more (2009-11-02)
