Phys.org / Megafire kills Joshua trees, but not fungi
When the Dome Fire tore through the Mojave Desert in 2020, it reduced 1 million Eastern Joshua trees to blackened skeletons. Scientists expected the underground ecosystem to be equally devastated. Instead, they found it thriving.
Phys.org / Red dwarf stars detected 'eating' Earth-like planets
Astronomers have found some of the strongest evidence yet that stars can swallow their own planets. A new study, published in Monthly Notices of the Royal Astronomical Society, supports the long-held belief that young stars ...
Tech Xplore / People prefer to talk to chatbots that share similar personality traits to their own, research shows
It's well understood that people tend to be naturally drawn to those with bubbly and extroverted personalities. And those outgoing and gregarious types may naturally consider themselves people-persons and gravitate toward ...
Phys.org / 'Feathered dragon' has some of the longest tail feathers ever found on a fossil bird
Birds have all kinds of fancy decorations for attracting mates—male peacocks have a fan of feathers accented with shimmering blue eye-spots, birds of paradise do courtship dances that highlight their fluffy plumes, and female ...
Tech Xplore / It looks like a sea urchin, but this strange 20-legged machine is rewriting what robots can do
Symmetry is everywhere in nature, from the bilateral form of vertebrates to the radial geometry of starfish. For decades, roboticists have tried to copy these shapes and their abilities with bodies that look like humans, ...
Phys.org / Humans reshape predator-prey rules across food webs, creating a challenging new world for wildlife
The relationship between predators and prey in the wild is underscored by an evolutionary arms race spanning millions of years, but new research has found modern human activity is reshaping the rules.
Phys.org / Moon base missions face an unseen threat, and these simulations show where it could strike first
Researchers have developed a novel virtual model for simulating how astronauts in future moon base operations might interact with each other and with their environment, with preliminary simulations revealing potential opportunities ...
Tech Xplore / Energy crunch fuels car pool growth
Rising fuel prices triggered by the Middle East war are driving a sharp increase in carpooling, with a ride-sharing platform reporting a surge in new users seeking cheaper ways to travel.
Phys.org / Mineral clues in Gale Crater track ancient Mars climate change
While NASA imagery has shown evidence of ancient rivers and lakes on Mars that transitioned to dry dunes, uncertainty remains over the timing of the environmental changes that may have contributed to these shifts.
Phys.org / New ammonia-making method could upend one of industry's dirtiest processes
As our world's population grows, so does the demand for ammonia—a key ingredient in fertilizer. The International Renewable Energy Agency estimates that ammonia production must quadruple by 2050 to feed the increase in global ...
Tech Xplore / Sodium-ion batteries could become a low-cost rival to Tesla's batteries
A popular sodium-ion battery designed by the company Hina and used in cars and large-scale energy storage systems in China matches performance parameters and production quality of Tesla's lithium-ion batteries, finds new ...
Medical Xpress / Endocannabinoid drop links to severe acute pancreatitis, offering possible treatment target
A study led by researchers from the Respiratory and Immune Repair (REPAIR) group at the Germans Trias i Pujol Research Institute (IGTP), in collaboration with researcher Daniel Closa from IIBB-CSIC, Enrique de-Madaria from ...
