Artificial intelligence successfully predicts protein interactions

Researchers used artificial intelligence (AI) and evolutionary analysis to produce 3D models of eukaryotic protein interactions. The study identified more than 100 probable protein complexes for the first time and provided structural models for more than 700 previously uncharacterized ones. Insights into the ways pairs or groups of proteins fit together to carry out cellular processes could lead...

Research in mice shows how diet alters immune system function through a gut microbe

Research in mice demonstrates how diet alters a gut microbe molecule that, in turn, prompts immune cells to downregulate inflammation. The study elucidates molecular mechanism behind long-standing belief that diet, microbiota, and immunity influence one another in myriad ways. If affirmed in larger animals and humans, the findings could inform the design of small-molecule drugs that regulate...

Invention lets people pay for purchases with a high-five

Imagine your car starting the moment you get in because it recognizes the jacket you're wearing. Consider the value of a hospital gown that continuously measures and transmits a patient's vital signs. These are just two applications made possible by a new 'body area network'-enabling fabric.

Team develops new screening process; could lead to next-generation therapeutics for a broad spectrum of diseases

A new study led by University of California, Irvine researchers developed a high-throughput screen methodology to identify compounds affect a key G protein coupled receptor (GPCR) rhodopsin (Rh). GPCRs mediate many important physiological functions and are considered to be one of the most effective therapeutic targets for a broad spectrum of diseases, ranging from diabetes to immune system...

Artificial intelligence successfully predicts protein interactions

UT Southwestern and University of Washington researchers led an international team that used artificial intelligence (AI) and evolutionary analysis to produce 3D models of eukaryotic protein interactions. The study, published in Science, identified more than 100 probable protein complexes for the first time and provided structural models for more than 700 previously uncharacterized ones. Insights...

Bucket brigades and proton gates: Researchers shed new light on water's role in photosynthesis

Photosystem II is a protein in plants, algae and cyanobacteria that uses sunlight to break water down into its atomic components, unlocking hydrogen and oxygen. A longstanding question about this process is how water molecules are funneled into the center of Photosystem II, where water is split to produce the oxygen we breathe. A better understanding of this process could inform the next...

Studying learner engagement during the COVID-19 pandemic

While massive open online classes (MOOCs) have been a significant trend in higher education for many years now, they have gained a new level of attention during the COVID-19 pandemic. Open online courses became a critical resource for a wide audience of new learners during the first stages of the pandemic—including students whose academic programs had shifted online, teachers seeking online...

Researcher works for diversity and inclusion in sciences, one journal at a time

A University of Rhode Island researcher and colleagues who study invasive species have published a series of articles in the journal Biological Invasions aimed at identifying and addressing concerns about diversity, equity and inclusion in the journal, which they believe will lead to a better understanding of invasive species around the world.

How thinking like a watershed system can help save Narragansett Bay

The Narragansett Bay, which covers almost 150 square miles along the coast of Rhode Island and Massachusetts, is New England's largest estuary, and it is under threat from both changing patterns of land use in New England and global climate change. Recently, researchers at the University of Massachusetts Amherst published the results of a new study that connects land use, the coast and the...

Russia admits to anti-satellite missile test but denies ‘dangerous behavior’

US officials accuse Moscow of ‘irresponsible’ behavior after it conducts test that threatened lives of astronauts onboard the ISSRussia has admitted to destroying one of its satellites during a missile test but rejected US accusations that it had endangered the International Space Station.US officials on Monday accused Moscow of “dangerous and irresponsible behavior” after it conducted an...

Sports leagues can fight climate change with lockdown-era schedules, research shows

The past two North American pro-sports seasons have been exceptional in many ways: Fewer games played, more regional travel and more same-city "baseball-style" series with consecutive matchups between the same home and visiting teams. It was an unusual experience for everyone involved, but a good one for the environment, writes Concordia researcher Seth Wynes.
