The discovery of room-temperature superconductors would open a huge range of applications and new technologies. There are no physical laws that rule out such materials, according to a recent perspectives article by a group of scientists including Warren Pickett, Distinguished Professor Emeritus of physics and astronomy at UC Davis.
In a new paper appearing in the Proceedings of the National Academy of Sciences, Vermeij and his research colleague Tracy Thomson catalogued the features of various mollusks in the fossil record and found that early mollusks evolved a unique physical trait once every 2 million years. That frequency began declining roughly 444 million years ago to about one new feature every 9 million years.
New research from the University of California, Davis, the Chinese Academy of Sciences and Texas A&M University reveals that massive emissions, or burps, of carbon dioxide from natural earth systems led to significant decreases in ocean oxygen concentrations some 300 million years ago.
University of California, Davis, researchers have developed a new, neuroplasticity-promoting drug closely related to LSD that harnesses the psychedelic’s therapeutic power with reduced hallucinogenic potential. The research highlights the new drug’s potential as a treatment option for conditions like schizophrenia, where psychedelics are not prescribed for safety reasons.
The extent to which “civilization” heightens or lessens the likelihood of violent conflict throughout human history has remained one of the most enduring questions among anthropologists. But a new collaborative study of archaeological groups from the Andes region of South America suggests that being part of a centrally organized state society is only part of the equation.
A new study published in the Proceedings of the National Academy of Sciences shows that there is an association between how songs sound and their place in our emotional lives. Sourcing songs from across the globe, Manvir Singh and his fellow researchers found that people from different types of societies can successfully identify a song’s type by how it sounds, regardless of the language of its words.
