Phys.org / Space junk falls to Earth faster when sunspots peak, reshaping satellite collision forecasts
Solar emissions exert 'drag' on space junk orbiting Earth. From historical measurements across a period of 36 years, researchers have now shown that space junk begins to fall down much faster once the sun's activity across ...
Phys.org / On the ground or in the atmosphere? Swarm satellites help characterize and pinpoint destructive events
When solar storms strike Earth, they can disrupt power grids, rail systems, satellites, and even marine life. These effects arise because solar wind and geomagnetic activity disturb the magnetosphere–ionosphere system, generating ...
Phys.org / Radical shifts to sustainability call for a new kind of legal thinking, researchers argue
Individual environmental laws, such as those related to the climate or nature conservation, are not sufficient on their own to resolve environmental crises. A new international study led by the University of Eastern Finland ...
Phys.org / Archaeologists reveal secrets of prehistoric human-made island
Archaeologists from the University of Southampton have excavated and recorded a large timber platform hidden beneath what today appears to be a stone-built island, located in a Scottish loch. They used a technique called ...
Medical Xpress / Bariatric surgery more effective than GLP-1 drugs at preventing heart attacks, stroke and death in older adults
Metabolic and bariatric surgery offers significantly greater long-term protection against heart attack, stroke and death than widely used GLP-1 drugs in older adults with obesity and diabetes, according to a new real-world ...
Science X / The root of the problem: Ancient trees may have grown their roots backwards
Secrets about how giant trees grew in reverse can be found in fossil imprints of their roots. Micro-CT scanning shows that the roots were growing tip-to-tail like shoots.
Medical Xpress / Brain-based index may reveal Alzheimer's risk patterns in adults as young as 30
Over the past few decades, neuroscientists and medical researchers worldwide have been trying to leverage available health records, brain scans and other medical data to uncover biological markers associated with the onset ...
Phys.org / Astronomers map lifetime of over 100,000 molecular clouds across 66 galaxies
An international team of astronomers has analyzed the data from the James Webb Space Telescope (JWST) and Atacama Large Millimeter/submillimeter Array (ALMA) to investigate giant molecular clouds in nearby galaxies. The new ...
Phys.org / JWST pins down the origins of a planetary odd couple
Across the Milky Way galaxy, a planetary odd couple is circling a star some 190 light years from Earth. A normally "lonely" hot Jupiter is sharing space with a mini-Neptune, in a rare and unlikely pairing that's had astronomers ...
Phys.org / PEG400 reveals parasite-only pocket that could sharpen malaria treatment
Research published in The FEBS Journal may help overcome challenges to the treatment of malaria—a tropical disease caused by infection of red blood cells with Plasmodium parasites, which are transmitted through infected mosquito ...
Phys.org / With large DNA fragment assembly, scientists can design microbes that produce countless complex products
A review in Quantitative Biology demonstrates that scientists can now reliably build and combine very large pieces of DNA, making it much easier to redesign microbes such as yeast and bacteria to act as efficient "cell factories." ...
Phys.org / Colored microplastics could be making global warming worse
There's more bad news about microplastics. We already know they pose a risk to health and can pollute ecosystems, but now researchers have discovered that tiny plastic particles drifting in Earth's atmosphere could be a significant ...
