Glucagon receptor structures uncover new arrestin interaction mechanism
G protein-coupled receptors (GPCRs) are essential for cell signal transduction and constitute the largest drug target protein family. Upon agonist stimulation, these receptors activate multiple downstream transducers, including G proteins and arresti.....»»
When plants flower: Scientists ID genes, mechanism in sorghum
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Oklahoma State University have identified key genes and the mechanism by which they control flowering in sorghum, an important bioenergy crop. The findings, just p.....»»
New study finds the malaria parasite generates genetic diversity using an evolutionary "copy-paste" tactic
By dissecting the genetic diversity of the most deadly human malaria parasite—Plasmodium falciparum—researchers at EMBL's European Bioinformatics Institute (EMBL-EBI) have identified a mechanism of 'copy-paste' genetics that increases the genetic.....»»
Natural tech for "dimming" genes brings transformative potential to agriculture
Until the 1992 advent of a tomato that could delay softening, the fruit was picked green to withstand shipping. The delayed-softening trait was an example of the gene-silencing technique RNA interference, RNAi, before the underlying mechanism was und.....»»
Scientists use James Webb Space Telescope to uncover clues about Neptune"s evolution
A ring of icy rocks orbiting our sun just beyond Neptune may give us a glimpse of how Neptune—and other objects in the outskirts of our solar system—were formed......»»
How insects tell different sugars apart
Whereas humans have one receptor on their tongues that can detect all sorts of sweet things, from real sugar to artificial sweeteners like aspartame, insects have many receptors that each detect specific types of sugars. Yale researchers have now unc.....»»
Archaeologists uncover the heritage of a marginalized community
Archaeologists have excavated the former working-class neighborhood of Vaakunakylä near Oulu, west-central Finland and interviewed its previous inhabitants, revealing the rich heritage of this marginalized community......»»
James Webb Space Telescope captures the end of planet formation
The James Webb Space Telescope (JWST) is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars......»»
Researchers develop amphibian-inspired camouflage skin
Inspired by amphibians such as the wood frog, investigators designed and synthesized a new type of camouflage skin involving one-dimensional photonic crystal structures assembled in three-dimensional flexible gels......»»
Unlocking the mechanism of pineapple internal browning
Internal browning (IB) is a significant post-harvest issue in pineapples, impacting fruit quality and leading to substantial losses, yet its mechanism remains poorly understood. Studies have shown that the accumulation of phenolic compounds plays a k.....»»
Study elucidates regulation mechanism for electrocatalytic nitrate reduction
A research team led by Prof. Zhang Haimin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has conducted a systematic study on the regulation mechanism of heterostructure bimetallic phosphide electrocatalysts to improv.....»»
Molecular mechanism of transmembrane bilirubin transport by human ABCC2 transporter revealed
The metabolic process of bilirubin has been a focus of medical research since the abnormal accumulation of bilirubin has been found to be associated with a variety of diseases. Bilirubin is a substance produced by the breakdown of aging or damaged re.....»»
Printing the future: Tailoring chemistry for inorganic 3D micro-optics
In a recent publication in the journal Trends in Chemistry, researchers from the University of Twente delve into the potential of 3D printing ceramics in micro-optics. These tiny ceramic structures can potentially be used to generate light and store.....»»
X Video Spaces is now available, offering live video interaction
X live video is now available inside the Spaces feature. Previously, the group chat feature only supported live audio. However, the feature is somewhat different from the Periscope service which Twitter bought and later replaced with an integrated.....»»
Study finds drought fuels invasive species after wildfires
In a study recently published in the journal Ecology, University of California, Irvine scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems......»»
Scientists discover why ripe fruit is more susceptible to necrotrophic pathogens than unripe fruit
In a recent study published in Molecular Plant, researchers have elucidated the mechanism underlying the increased susceptibility to necrotrophs during fruit ripening and have developed a rapid strategy to improve tomato fruit resistance to necrotrop.....»»
Study reveals accelerated soil priming under climate warming
A first-of-its-kind study led by researchers at the University of Oklahoma highlights a crucial biosphere feedback mechanism and its effects on releasing soil carbon into the atmosphere......»»
Fluorescent protein outshines the competition when imaging cells
Delicate cellular structures and dynamic processes within cells that were hitherto unseen could be revealed by the next generation of a green fluorescent protein developed by chemists at RIKEN......»»
Researchers offer theoretical description of topological water wave structures
Topological wave structures are wave patterns that exhibit specific topological properties, or in other words, properties that remain unvaried under smooth deformations of a physical system. These structures, such as vortices and skyrmions, have attr.....»»
Live imaging reveals key cell dynamics in 3D organ formation in Drosophila
Animal development requires successive changes in cell and tissue structures. To form complex 3D organs, cell shapes must adapt to support tissue morphogenesis. However, our understanding of how cellular structure changes are coupled with dynamic tis.....»»
