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 / Gene discovery opens new path for disease-resistant rice breeding
Bacterial blight (BB) is a serious plant disease that mainly affects rice plants, especially in warm, humid regions. Due to the severity of BB, discovering and applying BB-resistance genes is strategically important for ensuring ...
Phys.org / Laser method unlocks 3,000-Kelvin thin-film synthesis for quantum materials
Thin films might not come up in conversation every day, but they are all around us. Take the metallic plastic films of chip bags, for example, or the anti-reflective coatings on eyeglasses. Even the coatings on pills that ...
Phys.org / Cancer's hidden switch may sit in the cell membrane, forcing growth receptors into permanent overdrive
Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do more than simply provide ...
Phys.org / Temperature shifts change plant proteins that power photosynthesis
Humans adjust to changes in temperature by putting on a sweater or taking off layers. Plants adjust to temperature changes, in part, by switching the way they express the protein that performs the critical first step of photosynthesis, ...
Phys.org / Sex pheromone of a sandgrain-sized insect deciphered
Parasitic wasps of the genus Trichogramma are among the smallest insects in the world—yet they play an important role in natural ecosystems and agricultural landscapes as natural antagonists of pest species. Research teams ...
Phys.org / Closing the carbon cycle: Unraveling the roles of light and heat in CO₂ photocatalysis
Rising carbon dioxide (CO2) emissions from human activities are the largest contributor to global warming. According to the International Energy Agency (IEA), global CO2 emissions reached an all-time high of 37.8 gigatons ...
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.
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 / Titan's lakes may spawn 10-foot waves in gentle winds, new model suggests
On a calm day, a light breeze might barely ripple the surface of a lake on Earth. But on Saturn's largest moon, Titan, a similar mild wind would kick up 10-foot-tall waves. This otherworldly behavior is one prediction from ...
Phys.org / Laser-plasma accelerator drives free-electron laser for record 8 hours
For the first time, researchers have demonstrated that a laser-plasma accelerator can reliably drive a free-electron laser for more than eight hours. Published in Physical Review Accelerators and Beams, the result was achieved ...
