Using NCAR computer models of climate and vegetation, Benjamin Felzer found which plant types ancestors would have walked among during the last glacial maximum. The model reveals a global picture of vegetation 21,000 years ago, with significant changes in central Asia and Africa.
A recent study published in the journal Stroke found that patients who receive primary care from a neurologist after a stroke have better survival rates and less disability. This is in contrast to those cared for by generalists, where death rates are higher despite similar short-term costs.
Researchers at Scripps have discovered a previously unknown relationship between a protein in eggs and a protein on white blood cells, potentially leading to new treatments for leukemia. The protein structure reveals a molecular cavity that can be modified to alter signal transmission and eliminate leukemia cells.
A new study suggests the Yucatan asteroid impact was particularly deadly to North America due to its oblique angle, spreading energy northwest. The severe extinction intensity was highest downrange of the impact in North America.
Researchers Ebersole and Miller analyzed fossil data and found no regional differences in extinction rates during the Late Permian mass extinction event. They also discovered that environmental zones and latitude had little impact on the severity of the extinction, suggesting a global cause.
Scientists are installing a network of 250 Global Positioning System (GPS) receivers to continuously measure the movement of earthquake faults in southern California. The data will enable researchers to forecast future earthquake hazards and prioritize mitigation activities.
A team of scientists from the US, France, Italy, CAR, and Congo conduct a rare study of the African atmosphere, exploring biomass burning, rainforest-savanna boundaries, and global air chemistry. The EXPRESSO project collects chemical data to understand how vegetation and fires interact with the atmosphere.
