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...

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.

Life experience shapes dogs' interaction with humans

 It's an everyday scene. Pooch wants a tasty-looking piece of cake that's sitting on the table. What does he do? He gazes longingly at the titbit, ogles his master or mistress, and glances back at the cake. This "conversation" with humans gets him what he wants.

Serotonin found to be an important factor in calcium homeostasis in dairy cows

Maternal physiology of dairy cows shifts at the onset of lactation to adapt to the immense nutrient demands by the mammary gland, resulting in altered tissue metabolism. Research over the last decade has focused on understanding the shift in calcium metabolism, with an emphasis on the relationship of serotonin with calcium during the transition period and lactation. In a new review in the December...

Game theory and economics show how to steer evolution in a better direction

Human behavior drives the evolution of biological organisms in ways that can profoundly adversely impact human welfare. Understanding people's incentives when they do so is essential to identify policies and other strategies to improve evolutionary outcomes. In a new study publishing November 16th in the open access journal, PLOS Biology, researchers led by Troy Day at Queens University and David...

Rice varieties with a high endosperm lipid content reduce starch digestibility and increase γ-oryzanol bioaccessibility

According to the Healthy China Initiative, the incidence rate of diabetes is 12.8% in China, with about 150 million patients, and the incidence rate of dyslipidemia is 18.6%, with about 160 million patients. Common rice has a relatively high percentage of digestible starch and is therefore considered as a kind of food with a high glycemic index (GI). Breeding new varieties of rice rich in...

Synthetic biology yields easy-to-use underwater adhesives

Several marine organisms, such as mussels, secrete adhesive proteins that allow them to stick to different surfaces under sea water. This attractive underwater adhesion property has inspired decades of research to create biomimetic glues for underwater repair or biological tissue repair. However, existing glues often do not have the desirable adhesion, are hard to use underwater, or are not...

Janitorial culture of abuse documented by Worker Institute

Experiences of workplace sexual assault and harassment are widespread in the janitorial industry, according to a new report by the ILR School's Worker Institute, with women janitors more likely than men to experience unwanted sexual behavior, to be targeted by supervisors and to switch jobs due to harassing behavior.
