University of Illinois geologist Lijun Liu and his team have created a computer model of tectonic activity so effective that they believe it has potential to predict where earthquakes and volcanoes will occur. Liu, along with doctoral student Jiashun Hu, and Manuele Faccenda from the University of Padua in Italy, published a research paper in the journal of Earth and Planetary Science Letters focusing on the deep mantle and its relationship to plate tectonics.
Viruses are thought to frequently kill their host bacteria, especially at high microbial density. A state called lysogeny, in which viruses lie dormant but don't kill their hosts, has been thought to be relatively rare , mostly occurring at low bacterial concentrations. A new study suggests lysogeny might be much more common than previously believed. These findings could lead to a better understanding of degraded coral reef ecosystems and how to preserve them.
Evidence from the age of the dinosaurs to today shows that chemical weathering of rocks is less sensitive to global temperature, and may depend on the steepness of the surface. The results call into question the role of rocks in setting our planet's temperature over millions of years.
UNLV research in Russia challenges widely held understanding of past climate history; study appears in latest issue of top journal Nature Geoscience.
Over the week of May 15, extreme rainfall drenched northeastern Australia and NASA data provided a look at the record totals.
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.
Falling sulfur dioxide emissions in the United States are expected to substantially increase rainfall in Africa's semi-arid Sahel, while bringing slightly more rain to much of the US, according to a new study in the Journal of Geophysical Research: Atmospheres.
Researchers have found that carbon particles released into the air from burning trees and other organic matter are much more likely than previously thought to travel to the upper levels of the atmosphere, where they can interfere with rays from the sun -- sometimes cooling the air and at other times warming it.
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.
A new study has found that children, especially boys, whose mothers were exposed to higher levels of outdoor particulate air pollution at the same time that they were very stressed were most likely to develop asthma by age six. The study was presented at the 2017 American Thoracic Society International Conference.
