Observatory reveals key evidence of cosmic ray acceleration limit in W51 for first time
The Large High Altitude Air Shower Observatory (LHAASO) officially released the precise measurements of high-energy gamma radiation from the W51 complex, confirming it as a cosmic-ray accelerator boosting particles up to so-called ultra-high energies.....»»
Shedding light on the mechanism of yeast DNA repair
DNA damage is a cellular phenomenon that introduces structural abnormalities in double-stranded DNA. External factors, such as radiation or chemical agents, as well as internal factors, such as blocked DNA replication, can generate double-strand brea.....»»
NASA study tallies carbon emissions from massive Canadian fires
Stoked by Canada's warmest and driest conditions in decades, extreme forest fires in 2023 released about 640 million metric tons of carbon, NASA scientists have found. That's comparable in magnitude to the annual fossil fuel emissions of a large indu.....»»
Climate change feedbacks lead to surge in natural methane emissions
Attempts to cut greenhouse gases made tougher by increased emissions. Enlarge / A view of the Pantanal wetlands in Brazil. New research shows a large chunk of global methane emissions are from rotting vegetation in tropical wetla.....»»
Efforts to modernize the Columbia River Treaty provide an opportunity to right the wrongs of the past
The Columbia River Treaty is a landmark water-management agreement, ratified in 1964, by the United States and Canada which aimed to co-ordinate water management within the Columbia River Basin, particularly through the construction of four large dam.....»»
Nanotubes boost: Liquid-phase synthesis unlocks efficient production
Single-walled carbon nanotubes (SWCNTs) are known for their remarkable properties, which make them essential in many advanced technologies. Yet, creating these nanotubes efficiently and on a large scale has been a persistent challenge......»»
Towards a large materials model for AI-driven materials discovery
Following the success of large language models, the concept of large materials models as deep-learning computational models for materials design has attracted great interest. Nevertheless, the task of acquiring large materials models appears to be qu.....»»
Investigating adaptive strategies of high and low nucleic acid prokaryotes

Two strategies to protect your business from the next large-scale tech failure
The CrowdStrike event in July clearly demonstrated the risks of allowing a software vendor deep access to network infrastructure. It also raised concerns about the concentration of digital services in the hands of a few companies. A prescient Reddit.....»»
Test of a prototype quantum internet runs under New York City for half a month
To introduce quantum networks into the marketplace, engineers must overcome the fragility of entangled states in a fiber cable and ensure the efficiency of signal delivery. Now, scientists at Qunnect Inc. in Brooklyn, New York, have taken a large ste.....»»
Researchers identify effective materials for protecting astronauts from harmful cosmic radiation on Mars
Researchers have identified specific materials, including certain plastics, rubber, and synthetic fibers, as well as Martian soil (regolith), which would effectively protect astronauts by blocking harmful space radiation on Mars. These findings could.....»»
NASA"s DART impact permanently changed the shape and orbit of asteroid moon, new study shows
When NASA's Double Asteroid Redirection Test (DART) spacecraft collided with an asteroid moon called Dimorphos in 2022, the moon was significantly deformed—creating a large crater and reshaping it so dramatically that the moon derailed from its ori.....»»
Finally, a MacBook Pro rival that has what it takes
The Apple MacBook Pro 16 is arguably the best large laptop you can buy today. But it's also expensive and macOS-only. That's where the Asus ProArt P16 comes in......»»
Researchers demonstrate metasurfaces that control thermal radiation in unprecedented ways
Researchers with the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have experimentally demonstrated that metasurfaces (two-dimensional materials structured at the nanoscale) can precisely control the optical properties of t.....»»
