Science X / Ancient asteroid impact may explain Curiosity's first pure sulfur crystals on Mars
The bright yellow sulfur crystals discovered by NASA's Curiosity rover have puzzled scientists because sulfur on Mars is normally associated with mineral formations, not elemental deposits.
Phys.org / Frame-dragging observations validate Einstein yet again
More than a century after Albert Einstein first transformed our understanding of gravity, his general theory of relativity continues to withstand ever more demanding experimental tests. Now, an international team led by Ignazio ...
Medical Xpress / Rapid magnetic brain stimulation eases depression within days, but benefits fade within weeks
Despite decades of advances in mental health care, depression remains one of the world's most disabling conditions. Many people with major depressive disorder (MDD) fail to find lasting relief from antidepressants or psychological ...
Phys.org / Study reveals Hawaiian hotspot is getting hotter
Contrary to conventional geological thinking, the Hawaiian mantle plume has gotten hotter by about 250°C (480°F) over the past 47 million years. This discovery, led by Earth scientists at the University of Hawai'i at Mānoa, ...
Phys.org / Disturbance has a greater effect on giant kelp productivity than resource availability
Marine scientists at UC Santa Barbara have found that disturbances to giant kelp forests have a major influence on their net primary productivity (NPP)—an indicator of an ecosystem's health and its ability to support its ...
Tech Xplore / Engineers develop AI system to speed satellite tracking of wildfires
A new artificial intelligence system developed by West Virginia University engineers could help firefighters respond to wildfires sooner by enabling satellites to detect blazes and automatically adjust their positions for ...
Phys.org / Space cargo costs could fall more than 90% by 2040, study suggests
The expense of launching cargo into space will plummet over the next few years, with the cost of reaching orbit forecast to more than halve between now and the end of the decade, and fall by around 93% by 2040, according ...
Phys.org / Well-designed urban street plantings provide relief from summer heat
New research shows that improvements in tree, shrub and grass plantings along city streets in Queensland can substantially improve pedestrians' thermal comfort.
Phys.org / Lower-skilled workers could earn more in an AI world, research indicates
For anyone worried about AI's effects on jobs, here's good news: New research by Stanford economist Lukas Althoff concludes that artificial intelligence is likely to reshape jobs rather than eliminate entire occupations and ...
Phys.org / Underwater microphones detect dolphins in Sea of Japan bays about once every ten days
When residents of two coastal communities along the Sea of Japan reported observing dolphins in nearby waters, it caught the attention of some scientists. The marine environment has been changing rapidly in the Sea of Japan, ...
Medical Xpress / Unpaid caregivers shoulder more dementia costs than health systems in high-income Europe
Researchers found that 58% of total dementia-related costs are linked to unpaid care provided by family members, friends and other informal caregivers, highlighting the substantial burden of dementia beyond health care systems ...
Medical Xpress / Student-led study aims to improve diagnosis of early-onset dementia, a frequently misdiagnosed condition
Research led by a University of Sydney medical student could enable earlier and more accurate diagnosis of behavioral variant frontotemporal dementia—one of the most commonly misdiagnosed forms of early-onset dementia, which ...
