Blind cavefish typically have skulls that bend slightly to the left. A study by UC suggests this orientation might help them find food as they navigate in a perpetual counter-clockwise direction around a cave.
Research based on more than 180 fossil insects preserved in the La Brea Tar Pits of Los Angeles indicate that the climate in what is now southern California has been relatively stable over the past 50,000 years.
Natural and man-made disasters threaten millions of people every year and cause billions of property damage. How much do we know about them? And how can we use that knowledge to save lives and money? A recent report, compiled by the European Commission's Science and Knowledge Service (JRC), seeks to answer these and other questions and to help prepare for the time when disaster strikes.
Over the past century, the Northeast has experienced an increase in the number of storms with extreme precipitation. A Dartmouth-led study finds that the increase in extreme Northeast storms occurred as an abrupt shift in 1996, particularly in the spring and fall, rather than as a steady change over several decades. The findings were published in an early online release of the American Meteorological Society's 'Journal of Hydrometeorology.'
Scientists have developed a simple metric to capture the directional agreement between ocean currents and warming, revealing how ocean currents affect the range shift of marine biota in a changing climate.
The Pope's 2015 encyclical on climate change did not directly influence people's beliefs about the seriousness of climate change or its effect on the poor, a study in Cognition has found. The papal message did, however, indirectly influence people's beliefs about climate change by raising the Pope's credibility on that issue, most strongly among liberals.
Wolves and other top predators need large ranges to be able to control smaller predators whose populations have expanded, according to a study appearing May 23 in Nature Communications. The results were similar across three continents, showing that as top predators' ranges were cut back and fragmented, they were no longer able to control smaller predators.
A team of scientists have traced the evolution of whale size through more than 30 million years of history and found that very large whales appeared along several branches of the family tree about 2 to 3 million years ago. Increasing ice sheets in the Northern Hemisphere during this period likely altered the way whales' food was distributed in the oceans and enhanced the benefits of a large body size, the scientists say.
A new study of 67 less-developed, malaria-endemic nations led by Lehigh University sociologist Dr. Kelly Austin, finds a link between deforestation and increasing malaria rates across developing nations.
Scientists analyzing 7.2 million-year-old fossils uncovered in modern-day Greece and Bulgaria suggest a new hypothesis about the origins of humankind, placing it in the Eastern Mediterranean and not -- as customarily assumed -- in Africa, and earlier than currently accepted. The researchers conclude that Graecopithecus freybergi represents the first pre-humans to exist following the split from the last chimpanzee-human common ancestor.
