A massive decade-long study of Western Equatorial Africa's gorillas and chimpanzees has uncovered both good news and bad about our nearest relatives. The good news: there are one third more western lowland gorillas and one tenth more central chimpanzees than previously thought.



Researchers study how early humans thrived through volcanic winter

Wed, 25 Apr 2018 16:39:34 EDT

UTA researcher Naomi Cleghorn has participated in a Nature paper that describes how humans thrived in South Africa through the Toba volcanic eruption about 74,000 years ago, which created a decades-long volcanic winter.



Will warm-water events in the Gulf of California reduce seabird populations?

Wed, 25 Apr 2018 16:33:30 EDT

Oceanic warm-water events in the Gulf of California have increased in frequency during the last three decades, passing from a historic mean of one or two warm anomalies per decade to five events in the 2007-2016 period. This can lead to massive failures in seabird nesting, as anomalously warm waters accumulate in the ocean's surface, preventing the upwelling of colder, nutrient-rich waters from the ocean bottom, which in turn deprives seabirds of their food.



What happens when sea levels rise and coastal land gets flooded?

Wed, 25 Apr 2018 14:00:13 EDT

Due to climate change, sea levels are expected to rise and flood large, low-lying areas in many regions of the world. The big question is how we should cope—should we built dykes or let the sea in?



Many low-lying atoll islands could be uninhabitable by mid-21st century

Wed, 25 Apr 2018 14:00:13 EDT

Sea-level rise and wave-driven flooding will negatively impact freshwater resources on many low-lying atoll islands in such a way that many could be uninhabitable in just a few decades. According to a new study published in Science Advances, scientists found that such flooding not only will impact terrestrial infrastructure and habitats, but, more importantly, it will also make the limited freshwater resources non-potable and, therefore, directly threaten the sustainability of human populations.



Ultrahigh-pressure laser experiments shed light on super-Earth cores

Wed, 25 Apr 2018 14:00:06 EDT

Using high-powered laser beams, researchers have simulated conditions inside a planet three times as large as Earth.



Weather associated with sentiments expressed on social media

Wed, 25 Apr 2018 14:00:02 EDT

Sentiments expressed on Facebook and Twitter may be associated with certain weather patterns, according to a study published April 25, 2018 in the open-access journal PLOS ONE by Patrick Baylis from the Vancouver School of Economics, Canada, Nick Obradovich from the Massachusetts Institute of Technology, and colleagues.



Projectile cannon experiments show how asteroids can deliver water

Wed, 25 Apr 2018 14:00:02 EDT

Experiments using a high-powered projectile cannon show how impacts by water-rich asteroids can deliver surprising amounts of water to planetary bodies. The research, by scientists from Brown University, could shed light on how water got to the early Earth and help account for some trace water detections on the Moon and elsewhere.

Entanglement observed in near-macroscopic objects

Wed, 25 Apr 2018 13:00:09 EDT

Perhaps the strangest prediction of quantum theory is entanglement, a phenomenon whereby two distant objects become intertwined in a manner that defies both classical physics and a common-sense understanding of reality. In 1935, Albert Einstein expressed his concern over this concept, referring to it as "spooky action at a distance."



Next step towards quantum network based on micromechanical beams

Wed, 25 Apr 2018 13:00:08 EDT
