Phys.org / Uranus's two outer rings show starkly different origins
Astronomers using the W. M. Keck Observatory on Maunakea, Hawaiʻi Island are revealing new insight into the composition and origins of Uranus's two outer rings. Using data from the Keck Observatory Archive (KOA), combined ...
Phys.org / Supercomputer simulation predicts time-resolved porosity in die casting
Aluminum die-cast components are widely used in automotive and precision machinery applications due to their combination of low weight and structural strength. However, internal defects known as porosity—voids formed by entrapped ...
Phys.org / Climate impact of bottom fishing depends on where and how the seabed is disturbed
Bottom fishing can release CO₂ from the seabed, but the consequences for the climate are not straightforward. New research, published in the Journal of Applied Ecology, shows that disturbing the seabed sets in motion multiple ...
Phys.org / eROSITA disentangles the solar system's X-ray glow from deep-space signals
Max Planck Institute for Extraterrestrial Physics scientists have been able to disentangle the X-ray glow originating in our solar system from similar emission reaching us from deep space, using data from the SRG/eROSITA ...
Phys.org / Industrial chemical leaks could push ozone layer recovery back by 7 years
The recovery of the ozone layer in Earth's stratosphere could be delayed by several years, according to an international study led by Swiss research institution Empa which included contributions from University of Bristol ...
Phys.org / Bird and tortoise fossil tracks on South Africa's coast: Latest findings are world firsts
The south coast of South Africa's Western Cape province is a rich source of fossil tracks and traces—clues suggesting what this environment may have been like many thousands of years ago.
Medical Xpress / Cough drops from several brands being recalled, FDA says
Several common cough drop brands are being pulled from shelves after officials raised concerns about how they were made.
Medical Xpress / One-third with inflammatory bowel disease have moderate-to-severe disability, review finds
Moderate-to-severe disability affects nearly one-third of patients with inflammatory bowel disease (IBD), according to a review published online in Inflammatory Bowel Diseases.
Phys.org / For regrowing human limbs, this salamander gene could hold the key
Investigating a common gene in three very different species—salamanders, mice and zebrafish—scientists have discovered the potential for a novel gene therapy aimed at eventually regrowing limbs in humans, according to new ...
Medical Xpress / Fat cells steer flies away from pathogen-tainted food through a newly revealed neural circuit
If humans or animals eat something that causes them to feel unwell, they subsequently avoid this food source. Until now, it has been unclear precisely how this avoidance learning takes place. A new study shows that communication ...
Phys.org / Massive Atlantic sargassum blooms traced to West Africa
Massive blooms of Sargassum seaweed that have inundated coastlines across the Atlantic since 2011 likely originate off the coast of West Africa—forming years before they are visible and overturning long-standing assumptions ...
Phys.org / Electric double layer emerges in new electrocatalyst interface model
Hydrogen is at the heart of the transition to carbon neutrality, as both an energy carrier and a reagent for green chemistry. However, large-scale production of hydrogen via electrolysis, as well as the production of many ...
