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.....»»
New approach enhances accelerator"s capability to uncover clues from supernovae in lunar dust
Researchers at the China Institute of Atomic Energy (CIAE) have significantly enhanced the method of detecting iron-60 (60Fe), a rare isotope found in lunar samples, using the HI-13 tandem accelerator. This achievement paves the way for detecting 60F.....»»
Dyson spheres: Astronomers report potential candidates for alien structures, and evidence against their existence
There are three ways to look for evidence of alien technological civilizations. One is to look out for deliberate attempts by them to communicate their existence, for example, through radio broadcasts. Another is to look for evidence of them visiting.....»»
Researchers reveal a new mechanism of hyaluronic acid with a specific molecular weight to improve host inflammation
Previous studies on the function of glycosaminoglycans have primarily focused on improving host physiological indices. However, little attention has been paid to the material basis and mechanism of their mediated improvement of host health by gut mic.....»»
Scientists develop technique to analyze RNA structures in ultra-high definition
Scientists at the University of Nottingham have developed a technique to analyze the atomic-level structure of RNA molecules with exceptional precision and speed, and are the first in the world to use the method to examine structural changes in RNA w.....»»
Droplets that swim toward dissolution could inspire fluid microbots
Researchers discovered that microscopic liquid droplets swim toward solvent conditions that favor their dissolution. This mechanism may underlie some transport processes within living cells, and could be exploited to develop fluid micro robots......»»
First topological quantum simulator device in strong light-matter interaction regime to operate at room temperatures
Researchers at Rensselaer Polytechnic Institute have fabricated a device no wider than a human hair that will help physicists investigate the fundamental nature of matter and light. Their findings, published in the journal Nature Nanotechnology, coul.....»»
New insights into the interaction of femtosecond lasers with living tissue
Nonlinear light microscopy has revolutionized our ability to observe and understand complex biological processes. However, light can also damage living matter. Yet, the mechanism behind the irreversible perturbation of cellular processes by intense l.....»»
Scientists develop novel approach to interrogate tissue-specific protein–protein interactions
Multicellular organisms, like animals and plants, have complex cells with diverse functions. This complexity arises from the need for cells to produce distinct proteins that interact with each other. This interaction is crucial for cells to carry out.....»»
Study sheds light on how antibiotic "Velcro" kills bacteria
A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface, similar to how both sides of Velcro form a bond......»»
A merger of microbes: Study shows low-nutrient conditions alter viral infection
This much we know: When viruses infect bacteria—a common occurrence in oceans, soils, even human guts—the interaction results in the creation of entirely new organisms called "virocells." But scientists are still learning about how this merger of.....»»
Previously unknown dormouse habitat identified
Bayreuth researchers have shown for the first time that the dormouse, which is strictly protected in Germany, not only uses woody structures as a habitat, but also reed beds. The study is published in the Journal of Vertebrate Biology......»»
Research team uncovers mechanism for spikelet development in barley
The inflorescence architecture of crop plants like barley is predominantly regulated by meristem activity and fate, which play a critical role in determining the number of floral structures for grain production......»»
Veeam fixes auth bypass flaw in Backup Enterprise Manager (CVE-2024-29849)
Veeam has patched four vulnerabilities in Backup Enterprise Manager (VBEM), one of which (CVE-2024-29849) may allow attackers to bypass authentication and log in to its web interface as any user. With no user interaction required for remote exploitat.....»»
Green infrastructure plans need to consider historical racial inequalities, say researchers
Urban planners increasingly are interested in green infrastructure projects for the health and climate benefits they bring to cities. But without attention to historical development patterns and existing power structures, such projects may not benefi.....»»
Math discovery provides new method to study cell activity, aging
New mathematical tools revealing how quickly cell proteins break down are poised to uncover deeper insights into how we age, according to a recently published paper co-authored by a Mississippi State researcher and his colleagues from Harvard Medical.....»»
Researchers introduce programmable materials to help heal broken bones
Natural materials like bone, bird feathers and wood have an intelligent approach to physical stress distribution, despite their irregular architectures. However, the relationship between stress modulation and their structures has remained elusive......»»
Satellite radar data uncover "vigorous melting" at Antarctica"s Thwaites Glacier
A team of glaciologists led by researchers at the University of California, Irvine used high-resolution satellite radar data to find evidence of the intrusion of warm, high-pressure seawater many kilometers beneath the grounded ice of West Antarctica.....»»
Phycologists discover what makes some brown algae shimmer and others not
Compartments of consistently sized, tightly packed microspheres are what makes some brown algae shimmer like opal. The Kobe University discovery not only sheds light on the mechanism behind the alga's structural coloration, it is also the first to sp.....»»
U.S. Supreme Court backs consumer finance watchdog agency"s funding mechanism
Many conservatives and their Republican allies have portrayed the CFPB as part of an overbearing "administrative state," the network of agencies responsible for the array of federal regulations affecting businesses and individuals......»»
Researchers uncover how jelly sea creatures might shape modern robotics
Scientists at the University of Oregon have discovered that colonies of gelatinous sea animals swim through the ocean in giant corkscrew shapes using coordinated jet propulsion, an unusual kind of locomotion that could inspire new designs for efficie.....»»
