Ostrich relative lived in North America 50 million years ago
The new species is named Calciavis grandei -- with 'calci' meaning 'hard/stone,' and 'avis' from the Latin for bird, and 'grandei' in honor of famed paleontologist Lance Grande who has studied the fossil fish from the same ancient North American lake for decades.

Penn chemists establish fundamentals of ferroelectric materials
Chemists from the University of Pennsylvania are enabling the next generation of research into ferroelectric materials. In a new study, published in Nature, they demonstrate a multiscale simulation of lead titanate oxide that provides new understanding about what it takes for polarizations within these materials to switch.

From climate killer to fuels and polymers
Researchers have discovered a catalyst that performs highly selective conversion of the greenhouse gas carbon dioxide into ethylene -- an important source material for the chemical industry. In the journal Nature Communications, a team headed by Prof Dr Beatriz Roldan Cuenya from Ruhr-Universitšt Bochum describes how plasma-treated copper can be used for this purpose. The researchers have also decoded the mechanism underlying the improved behavior of the plasma treated catalyst.

Expanding Antarctic sea ice linked to natural variability
The recent trend of increasing Antarctic sea ice extent -- seemingly at odds with climate model projections -- can largely be explained by a natural climate fluctuation, according to a new study led by the National Center for Atmospheric Research.

Study finds that plant growth responses to high carbon dioxide depend on symbiotic fungi
Research by an international team of environmental scientists from the United Kingdom, Belgium and United States, including Indiana University, has found that plants that associate with one type of symbiotic fungi grow bigger in response to high levels of carbon dioxide, or CO2, in the atmosphere, but plants that associate with the other major type of symbiotic fungi do not.

UC Riverside anthropologist awarded NSF grant to excavate Maya households
An international team of researchers led by UC Riverside anthropologist Travis Stanton will begin excavating household sites in the ruins of Yaxuna, Coba and a rural community along a causeway on the YucatŠn Peninsula next summer in an effort to determine how life changed for tens of thousands of people who lived along what was the longest road in the ancient Maya world.

Ocean acidification affects predator-prey response
Ocean acidification makes it harder for sea snails to escape from their sea star predators, according to a study from UC Davis. The findings suggest that by disturbing predator-prey interactions, ocean acidification could spur cascading consequences for food web systems in shoreline ecosystems.

Findings show gender, not race, a factor in college engineering dropouts
Researchers from the University of Missouri and partner institutions are exploring how ethnic and gender variables affect retention rates, goal setting and satisfaction among engineering students. Preliminary findings in the middle of this five-year study found no differences in retention between Latino and white engineering students, but did show differences between men and women. Their study could help shape methods needed to retain students in engineering fields.

Researchers develop key power-splitting component for terahertz waves
One of the most basic components of any communications network is a power splitter that allows a signal to be sent to multiple users and devices. Researchers from Brown University have now developed just such a device for terahertz radiation -- a range of frequencies that may one day enable data transfer up to 100 times faster than current cellular and Wi-Fi networks.

Watching a forest breathe
For the first time, scientists traced carbon dioxide flows through a forest during photosynthesis and respiration, correcting long-standing assumptions about how plants exchange the greenhouse gas with the atmosphere on an ecosystem-wide level. The results could help make climate prediction models more accurate.

Men may face high lifetime risk of sudden cardiac death
One in nine men may be at higher risk of premature death due to sudden cardiac death - usually with no warning. One in 30 women may face the same risk. The study offers the first lifetime estimates for sudden cardiac death among Americans. High blood pressure and other cardiovascular risk factors were associated with a higher lifetime risk of sudden cardiac death -- a finding which could lead to screening methods for sudden cardiac death.

New study shows impact of man-made structures on Louisiana's coastal wetlands
As Louisiana's wetlands continue to disappear at an alarming rate, a new study has pinpointed the man-made structures that disrupt the natural water flow and threaten these important ecosystems. The findings have important implications for New Orleans and other coastal cities that rely on coastal wetlands to serve as buffer from destructive extreme weather events.
