Multistep mechanism of nanostructure formation in liquid crystal
Most of our daily commodities, such as plastics, alloys and processed foods, are provided as solids, and they are often processed by a controlled cooling process from a liquid mixture to a solid. Liquid crystals, solutions, polymers, and biomaterials.....»»
New research underscores the close relationship between Saharan dust and hurricane rainfall
Giant plumes of Sahara Desert dust that gust across the Atlantic can suppress hurricane formation over the ocean and affect weather in North America. But thick dust plumes can also lead to heavier rainfall—and potentially more destruction—from la.....»»
Stress granules found to play an unsuspected role in blood vessel formation
The behavior of the cells that make up our blood vessels is crucial to our well-being. Conditions such as inflammation, oxygen deprivation and viral infection can stress these cells and disrupt the formation of new, often pathological, blood vessels......»»
Next generation biosensor reveals gibberellin"s critical role in legume nitrogen-fixation
Researchers at the University of Cambridge have demonstrated that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size. They identified the speci.....»»
380-million-year-old rocks provide insights into past climate and geothermal energy
Rocks undergo changes over millions of years. Yet it is possible to extract information from them about the climate at the time of their formation......»»
Spontaneous supercrystal discovered in switching metal-insulator
A supercrystal formation previously unobserved in a metal-insulating material was discovered by a Cornell-led research team, potentially unlocking new ways to engineer materials and devices with tunable electronic properties......»»
Discovery of Piezo1"s new signaling mechanism may aid search for better pain and itch treatments
The human body's sense of touch is so important it can be found throughout the body, not just on the skin. Two tiny sensors of touch, Piezo1 and Piezo2, signal the lightest pressures and can be found monitoring the circulatory system, telling the bod.....»»
New liquid single nucleotide polymorphism chip can enhance rubber tree breeding
A research team developed and validated a liquid single nucleotide polymorphism (SNP) chip named "HbGBTS80K," which includes 80,080 SNPs evenly distributed across 18 chromosomes. This SNP chip effectively distinguished 404 rubber accessions into four.....»»
Researchers zero in on the underlying mechanism that causes alloys to crack when exposed to hydrogen-rich environments
When deciding what material to use for infrastructure projects, metals are often selected for their durability. However, if placed in a hydrogen-rich environment, like water, metals can become brittle and fail. Since the mid-19th century, this phenom.....»»
How mantle hydration changes over the lifetime of a subduction zone
Because of interactions with Earth's hot mantle, water-logged oceanic plates release water as they slide beneath less dense overriding plates in subduction zones. This water rises and hydrates the mantle above it, contributing to the formation of vol.....»»
Blue Origin shows off landing mechanism for New Glenn rocket
Blue Origin is aiming to land the first stage of its new rocket in late September, the New Glenn......»»
Scientists uncover the molecular mechanism behind pineapple peel coloration
Pineapple peel coloration, especially the red hue, significantly enhances its commercial and aesthetic value. However, the genetic mechanisms driving this trait are not well understood, complicating breeding efforts for red-skinned varieties......»»
Scientists identify brain circuits tied to the behavior of schooling fish
A flock of migrating geese glides through the summer sky in an unmistakable "V" formation… a thundering herd of bison rumbles across the plains as a formidable group... and a massive school of sardines swims mesmerizingly in unison......»»
Scientists develop dual-functional, high-efficiency antimicrobial nanozyme
A research team led by Prof. Gao Lizeng from the Institute of Biophysics of the Chinese Academy of Sciences proposed a bactericidal mechanism based on nanozymes that simulate antimicrobial peptides (AMPs) and antimicrobial enzymes (AMEs) according to.....»»
Grain boundaries weaken in planetary interiors, research suggests
Mantle convection and associated plate tectonics of planets like the Earth are governed by the deformation of mantle rocks. This deformation occurs through the motion of defects in the crystal lattices of minerals. Thus, the physical properties of th.....»»
Former OpenAI researcher’s new company will teach you how to build an LLM
Karpathy's Eureka Labs will pair human-made curriculum with an AI-powered assistant. Enlarge (credit: Getty Images) On Tuesday, former OpenAI researcher Andrej Karpathy announced the formation of a new AI learning platfo.....»»
Geophysics research finds microplastic pollution increases sea foam height and stability
From cloud formation to sea temperatures, sea foam plays many roles in the dynamic interactions that occur at the surface level of the world's oceans......»»
New analysis of Cassini data yields insights into Titan"s seas
A new study of radar experiment data from the Cassini-Huygens mission to Saturn has yielded fresh insights related to the makeup and activity of the liquid hydrocarbon seas near the north pole of Titan, the largest of Saturn's 146 known moons......»»
Not just space rocks: Six things we"ve learned about Earth from meteorites and comets
Apart from the sun, its planets and their moons, our solar system has vast amounts of space rocks—fragments left over from the formation of the inner planets......»»
E. coli variant may cause antimicrobial resistance in dogs, humans
Researchers studying antimicrobial-resistant E. coli—the leading cause of human death due to antimicrobial resistance worldwide—have identified a mechanism in dogs that may render multiple antibiotic classes ineffective......»»
Scientists develop new tool that could lead to noninvasive "liquid biopsies"
Biopsies are clinical tools commonly used to diagnose a variety of diseases or to monitor tissue for abnormal growth or even rejection of a transplant. During biopsies, tissue samples are removed from the body so they can be examined more closely, bu.....»»
