Pebbles on Mars likely traveled tens of miles down a riverbed, Penn study finds
A University of Pennsylvania-led team uses a new method to determine that rounded pebbles on Mars traveled roughly 30 miles down an ancient riverbed, providing additional evidence for the idea that Mars once had an extensive river system, conditions that could support life.

Fungi at root of plant drugs that can help, or harm, sick monarch butterflies
Previously, biologists discovered that butterflies use plant toxins as a drug to cure their offspring of parasitic infections. Now they've dug a little deeper and found that the fungi associated with the roots of milkweed plants change both the nutritional and medicinal chemistry of milkweed leaves.

Sixth sense: How do we sense electric fields?
A variety of animals are able to sense and react to electric fields, and living human cells will move along an electric field, for example in wound healing. Now UC Davis researchers have found the first actual 'sensor mechanism' that allows a living cell detect an electric field.

Climate models used to explain formation of Mars valley networks
The extensive valley networks on the surface of Mars were probably created by running water billions of years ago, but the source of that water is unknown. Now, a team of Penn State and NASA researchers is using climate models to predict how greenhouse warming could be the source of the water.

New optoelectronic probe enables communication with neural microcircuits
The burgeoning field of optogenetics makes it possible for scientists to control brain activity using pulses of light. Now, Brown University researchers have developed an optoelectronic device which opens the possibility of bidirectional communication with the brain. The new technology enables stimulation of neural microcircuits with millisecond precision according to predescribed space-time maps while monitoring changes in neural activity across the targeted microcircuits.

New Oregon approach for 'nanohoops' could energize future devices
When the University of Oregon's Ramesh Jasti began making tiny organic circular structures using carbon atoms, the idea was to improve carbon nanotubes for use in electronics or optical devices. Now he believes his technique might roll solo. In a new paper, his team shows that his cycloparaphenylenes can be made using a variety of atoms, not just those from carbon.

New study provides key insights into aspirin's disease-fighting abilities
Researchers at Boyce Thompson Institute have found a new explanation for how aspirin works in the body to reduce the risk of heart disease and certain cancers. Aspirin's active form, salicylic acid, blocks a protein called HMGB1, which triggers inflammation in damaged tissues. The new findings may explain the disease-preventing effects of a low-dose aspirin regimen and offer hope that more effective aspirin-like drugs may be developed for a wide variety of diseases.

Paleoclimate researchers find connection between carbon cycles, climate trends
Making predictions about climate variability often means looking to the past to find trends. Now paleoclimate researchers from the University of Missouri have found clues in exposed bedrock alongside an Alabama highway that could help forecast climate variability. In their study, the researchers verified evidence suggesting carbon dioxide decreased significantly at the end of the Ordovician Period, 450 million years ago, preceding an ice age and eventual mass extinction. These results will help climatologists better predict future environmental changes.

Engineers assist Bank of America Chicago Marathon with technology
A Northwestern University and Bank of America Chicago Marathon research team has custom-designed a data visualization system that provides a computer simulation of the race. Using data from the last seven Chicago Marathons and from runners in this year's race, the system can forecast where large concentrations of participants will be 20 minutes later, helping race officials plan accordingly. The simulation, course conditions, alerts and more will be displayed on large 'dashboards' in forward command during the Oct. 11 race.

Horn of Africa drying ever faster as climate warms
The Horn of Africa has become increasingly arid in sync with the global and regional warming of the last century and at a rate unprecedented in the last 2,000 years, according to new research. The scientists suggest that as global and regional warming continues, the eastern Horn of Africa -- which includes Somalia, Djibouti and Ethiopia -- will receive progressively less rain during the crucial 'long rains' season of March, April and May.

Caution: Shrinks when warm
Most materials swell when warm, and shrink when cool. But some weird materials do the opposite. Although thermal expansion, and the cracking and warping that often result, occurs everyday -- in buildings, electronics, and almost anything else exposed to wide temperature swings -- physicists have trouble explaining why solids behave that way. New research into a material that has negative thermal expansion may lead to a better understanding of why materials change volume with temperature at all.

The father effect
Inheritance is not just a matter of DNA. That's what a McGill University-led team has discovered. They believe that proteins known as histones, which have attracted relatively little attention until now, may play a crucial role in the process of transmitting a father's life experiences to his offspring and could play a determining role in the health of his children and grandchildren .
