| Artificial intelligence successfully predicts protein interactions Posted: 16 Nov 2021 02:51 PM PST 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 to a wealth of new drug targets. |
| Research in mice shows how diet alters immune system function through a gut microbe Posted: 16 Nov 2021 02:50 PM PST 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 immune response to treat inflammatory conditions |
| New screening process could lead to next-generation therapeutics for a broad spectrum of diseases Posted: 16 Nov 2021 02:50 PM PST Researchers have 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 disorders. |
| Posted: 16 Nov 2021 12:23 PM PST Researchers have revealed a striking pattern following a functional screen of extracts from plants collected in Muir Woods National Monument, in coastal redwood forest land in California. They found plants with a long history of use by Native Americans as topical analgesics, were often also used as gastrointestinal aids. |
| Game theory and economics show how to steer evolution in a better direction Posted: 16 Nov 2021 11:48 AM PST 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, researchers bring the tools of economics and game theory to evolution management. |
| Synthetic biology yields easy-to-use underwater adhesives Posted: 16 Nov 2021 10:17 AM PST Researchers have used synthetic biology to bring together the best of spider silk and mussel foot protein in a biocompatible adhesive. |
| Unique fossil: Seeds sprouting from an amber-encased pine cone Posted: 16 Nov 2021 10:17 AM PST New research has uncovered the first fossil evidence of a rare botanical condition known as precocious germination in which seeds sprout before leaving the fruit. |
| Swapping spit helps ants share metabolic labor Posted: 16 Nov 2021 08:13 AM PST Ant colonies use fluids passed mouth-to-mouth to create a colony-wide metabolism, shows a new study. |
| Scientists identify second HIV patient whose body appears to have rid itself of the virus Posted: 15 Nov 2021 06:29 PM PST In 2020, an untreated HIV patient was identified with no intact copies of HIV genomes in more than 1.5 billion blood cells analyzed, suggesting the virus had been cleared from the patient's body. Researchers now report a second untreated person living with HIV who had no evidence of intact HIV genomes in more than 1.5 billion blood and tissue cells analyzed. |
| Posted: 14 Nov 2021 05:17 PM PST In a study with lab-grown mouse cells, researchers say they have found that a protein that helps form a structural network under the surface of the cell's 'command center' -- its nucleus -- is key to ensuring that DNA inside it remains orderly. |
