UTSA criminology and criminal justice professors Michael R. Smith and Rob Tillyer working in collaboration with University of Cincinnati Professor Robin Engel examined racial and ethnic disparities in the use of force by the Fairfax County Police Department (FCPD). One of the nation's largest county police departments, the FCPD serves Fairfax County, Va., a major metropolitan county near Washington, D.C.

A 50% rise in the level of carbon dioxide (CO2) in the atmosphere could reduce rainfall in the Amazon as much as or even more than substitution of the entire forest by pasture. The rise in CO2 would reduce the amount of water vapor emitted by the forest, leading to a 12% annual drop in the volume of rainfall, while total deforestation would reduce rainfall by 9%.

For many years, researchers have been focused on developing technologies that can help us fight the imminent climate change crisis. They have one goal in common: Finding sustainable energy sources that can replace the environmentally toxic fossil fuels. Photocatalysts that drive an artificial process that replicates photosynthesis (in which solar energy is converted to useful materials) are promising in this regard, given that we are able to develop the technology needed for them. Crystalline materials... Читать дальше...

Billionaire entrepreneur Elon Musk said Tuesday he plans to invest up to 30 billion dollars to develop his ambitious Starlink satellite internet service.

This lobster tale begins a few years ago when the proprietor of a northeastern seafood restaurant publicly asserted that exposing lobsters to a little cannabis prior to cooking produced notable changes in their behavior and a less dramatic scene in the kitchen for all concerned, which was the Maine thing.

A process that uses heat to change the arrangement of molecular rings on a chemical chain creates 3D-printable gels with a variety of functional properties, according to a Dartmouth study.

Some regions of the human genome where the DNA can fold into unusual three-dimensional structures called G-quadruplexes (G4s) show signs that they are preserved by natural selection. When G4s are located in the regulatory sequences that control how genes are expressed, or in other functional but non-protein coding regions of the genome, they are maintained by selection, are more common, and their unusual structures are more stable, according to a new study. Conversely, the structures are less common... Читать дальше...

The story of halichondrin B, an inspirational molecule obtained from a marine creature, goes back to the molecule's discovery in an ocean sponge in 1986.

The Florida Aquarium has reached another major milestone in its mission to restore the coral reefs, thanks to crossbreeding and cryopreservation.

China has announced a temporary ban on its fishing fleet—the world's biggest—from catching squid in parts of the Pacific and Atlantic Oceans after overfishing pushed populations to the brink of collapse.

A baby gorilla has been born in the wild in Gabon from two parents who grew up in captivity in Europe, in a world-first that was hailed by conservationists of the endangered species on Tuesday.

Over the past few decades, roboticists have developed a variety of robots inspired by nature, humans and animals. To effectively mimic animals or humans, however, these robots should not only look like them; they should also move in similar ways.

Using the Keck I telescope, Japanese astronomers have identified a massive quiescent galaxy in a distant galaxy protocluster known as SSA22. The galaxy, designated ADF22-QG1, turns out to be the most distant quiescent galaxy in a protocluster to date. The finding is reported in a paper published June 21 on the arXiv pre-print repository.

A trio of researchers, one from Saint Louis University, the other two from the University of Chicago, has found that offering double-dose algebra instruction to struggling 9th grade students can lead to later benefits in college—but only if the students are paired with helpful peers. In their paper published in Proceedings of the National Academy of Sciences, Takako Nomi, Stephen Raudenbush, and Jake Smith describe their study that involved monitoring the achievements of students who took part in...

A team of researchers from Spain, France and the U.S. has found evidence of a glauconitic-like clay on Mars that suggests the planet once had habitable conditions. In their paper published in the journal Nature Astronomy, the group describes their study of clay minerals extracted from Gale Crater by Curiosity rover back in 2016 and what they found.
