Freshwater lakes across North America and Europe are becoming noticeably browner, reducing underwater visibility and reshaping fish populations。 Research found that several popular sport fish, including trout, bass, perch, and whitefish, tend to decline in darker waters。 Meanwhile, walleye and northern pike often become more abundant because they a
A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō。 The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long before humans arrived
Okies have dominated a competition with other senior living facilities for six seasons, but they’re not just there to win
Researchers found that a Chinese sodium-ion battery performs far better than expected, with production quality and design features comparable to Tesla’s batteries。 If engineers can improve cold-weather charging and energy density, sodium could become a cheaper and more abundant alternative to lithium for EVs and large-scale energy storage
TikZ is a widely-used LaTeX package for drawing figures in papers。 It uses commands like \draw[->] (0,0) -- (1,2); to draw lines, shapes, text, etc。 Academics usually code up their figures by hand, so there is lots of twiddling around with the coordinates and recompiling until things look nice
A newly proposed quantum sensing technique could make it much easier to identify one of physics’ newest and most intriguing classes of magnets: altermagnets。 These unusual materials, discovered only a few years ago, appear to combine the speed and efficiency of antiferromagnets with some of the useful electronic properties of traditional magnets, m
The global cobalt supply chain is more interconnected—and more vulnerable—than previously thought, with disruptions capable of triggering far-reaching cascades across multiple countries and industries。 Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn local shocks into
