Scientists reveal novel double-roaming mechanism in chemical reaction
Roaming, a novel mechanism in reaction dynamics, describes an unusual pathway that is quite different from the conventional minimum-energy path. It is facilitated by the initial frustrated dissociation to form radical products, and then the meanderin.....»»
AI and quantum mechanics team up to accelerate drug discovery
Drug discovery is much like working a jigsaw puzzle. The chemical compounds behind drug molecules must be shaped to fit with the proteins in our bodies to produce therapeutic effects. That requirement for a meticulous fit means the creation of new dr.....»»
The GALAH fourth data release provides vital data on one million stars in the Milky Way
For the past 10 years, Australia's ARC Center of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has been investigating star formation, chemical enrichment, migration, and mergers in the Milky Way with the Anglo-Australian Telescope (AA.....»»
Perseverance team revives SHERLOC instrument to help with Jezero crater discovery
In January 2024, the SHERLOC instrument aboard NASA's Mars 2020 Perseverance rover encountered a significant issue. A fault in the instrument's motor caused the dust cover and autofocus mechanism to become inoperative, putting the rover's SHERLOC Ram.....»»
Digging into neutrino research: LBNF-DUNE project moves forward with excavation of 800,000 tons of rock
As a kid, you may have tried to dig a hole in your backyard to reach China. Obviously, that didn't happen. But digging out a lot of ground can be quite productive. Instead of reaching another country, the scientists, engineers, and construction worke.....»»
Nobel Prize in medicine awarded for discovery of microRNAs, the molecules that control our genes
Two scientists, Victor Ambros (UMASS Chan Medical School in the US) and Gary Ruvkun (Harvard Medical School in the US), have won the 2024 Nobel prize in medicine or physiology......»»
Hurricane Helene"s reach was shocking, another example of how climate change "is here and now," scientists say
Many people were stunned to see the intense flooding and devastation caused by Hurricane Helene in western North Carolina communities, located inland and tucked thousands of feet above sea level in the Blue Ridge Mountains......»»
Unlocking heat management with quantum thermal transistors
Scientists are finding ways to use quantum effects to create groundbreaking thermal devices that can help cool electronic systems. The quantum thermal transistor is one of the most exciting innovations in this field. While the current works surroundi.....»»
Limestone and iron reveal puzzling extreme rain in Western Australia 100,000 years ago
Almost one-sixth of Earth's land surface is covered in otherworldly landscapes with a name that may also be unfamiliar: karst. These landscapes are like natural sculpture parks, with dramatic terrain dotted with caves and towers of bedrock slowly scu.....»»
Study of global primate populations reveals predictors of extinction risk
An international team of biologists, planetary scientists and conservationists has conducted a large-scale study of non-human primate populations around the world to gauge their risk of extinction due to climate change......»»
Using AI to figure out the chemical composition of paints used in classical paintings
A team of chemists and AI researchers at CNR, Istituto di Scienze del Patrimonio Culturale, has developed an AI model capable of determining the chemical composition of the paints used to make classical paintings......»»
Researchers reveal key mechanism in regulating DNA recombination
Meiotic recombination generates genetic diversity and promotes proper chromosomal segregation of parental chromosomes. This process requires a set of recombinases polymerized on single-stranded (ss) DNAs called the nucleoprotein filament to undergo h.....»»
Tip: You Can Change Pixel Buds Settings on Windows, Mac
Owning a pair of high-end earbuds in today’s world means you likely connect them to your phone and computer either simultaneously or with quick switching as you need it. That double device access allows you to jump from work life to phone life.....»»
Traces of antimatter in cosmic rays reopen the search for "WIMPs" as dark matter
One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes more than 85% of the matter in the universe), but we have never seen it directly and still do not know what it is......»»
Sentinel-2 data reveal significant seasonal variations in intertidal seagrass
With data from the Copernicus Sentinel-2 mission, researchers have revealed seasonal variations in intertidal seagrass across Western Europe and North Africa. As a key indicator of biodiversity, these new findings offer valuable insights for the cons.....»»
Cellular agriculture research manages to culture pork fat tissue on rye protein scaffolds
National University of Singapore (NUS) food scientists have developed a simple and scalable method for culturing pork fat tissue using protein scaffolds made from secalin, a protein extracted from rye......»»
Scientists develop novel method for strengthening PVC products
Researchers have developed a way to make one type of plastic material more durable and less likely to shed dangerous microplastics. Their study has identified a secure way to attach chemical additives to polyvinyl chloride (PVC). The work is publishe.....»»
A new era of solar observation: International team produces global maps of coronal magnetic field
For the first time, scientists have taken near-daily measurements of the sun's global coronal magnetic field, a region of the sun that has only been observed irregularly in the past. The resulting observations are providing valuable insights into the.....»»
Scientists offer a detailed look at the skeleton of an ancient predator that thrived in extreme conditions
Imagine a world on the brink of collapse: volcanic eruptions spewing toxic gases, oceans turning acidic, and up to 90% of Earth's species vanishing in the blink of an eye. This was the reality at the end of the Permian Period, around 252 million year.....»»
