Scientists discover hidden math secret inside Chinese money plant leaves

One in four 2026 World Cup games could take place in very hot conditions as climate change has increased the risk of extreme heat in North America since the US hosted the 1994 tournament, researchers warned Thursday.

Scientists have finally cracked the mystery behind one of climate change’s strangest fingerprints: while Earth’s surface heats up, the upper atmosphere is rapidly cooling. Researchers at Columbia University discovered that carbon dioxide acts very differently high above the planet, where it actually helps radiate heat into space instead of trapping it. The team found that certain infrared wavelengths fall into a “Goldilocks zone” that becomes increasingly effective as CO2 levels rise, accelerati

Researchers in Japan traced a hidden medieval solar storm using ancient tree rings and centuries-old sky observations. The team linked reports of eerie red auroras with spikes of carbon-14 trapped in buried wood, revealing a powerful solar radiation event around 1200 CE. The findings suggest the Sun was far more active at the time, with unusually short solar cycles.

Scientists analyzing the genomes of thousands of people across Japan discovered evidence for a previously overlooked third ancestral group, challenging the long-accepted “dual origins” theory. The newly identified ancestry appears linked to the ancient Emishi people of northeastern Japan. Researchers also uncovered inherited Neanderthal and Denisovan DNA connected to conditions like diabetes, heart disease, and cancer.
