A newly identified fossil ape from northern Egypt is reshaping ideas about where the ancestors of modern apes first emerged。 Analyses place it closer to living apes than any known East African species of the same age, pointing to North Africa and the Middle East as a possible birthplace and crossroads for the ape lineage that eventually produced gi
A new analysis suggests the Sun holds far more silver than earlier estimates indicated。 More advanced models of the solar atmosphere raised the calculated amount by 55 percent, bringing it into much closer agreement with ancient meteorites。 The technique may also help scientists track the cosmic origins of silver and other heavy elements
The UK MET office recently redesigned their site, adding a lot of additional whitespace, scrolling, and animations。 This significantly reduced its usability for me, and left me wanting an ‘at a glance’ weather site。I made https://brolly
Cosmic expansion allows distant galaxies to move away faster than light, while still letting us see ancient light they emitted when they were much closer。 Eventually, accelerating expansion will push nearly every galaxy beyond our Local Group out of sight, making the Universe appear almost empty
Recycling, greener diets, and other personal climate choices do not seem to distract people from supporting major environmental reforms。 A four-year study of nearly 2,800 Australians found that these habits neither increased nor reduced later political engagement
Hi HN, I made some animations of the most important kinds of transistors using my semiconductor simulation, details of which are on the page。 I tried to make the visuals as realistic as possible while also aiming for clarity。 If you want to go beyond the charge carriers and look at, for example, the electric field, you can do so in the simulation s
The longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress。 The finding could open a new path toward treatments that mimic APOE2’s defenses in people at higher genetic risk for Alzheimer’s
Newer oral drugs related to semaglutide medications such as Ozempic reduced pleasure-driven eating in mice by quieting a deep brain reward circuit。 The finding could open new avenues for understanding food cravings and potentially treating substance use disorder
