Earth is flying through ancient supernova debris and scientists found the evidence in Antarctic ice

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.

Spring melt along Alaska’s Kuskokwim River caused ice jams and flooding.

Symbiosis, or the interaction of two unalike species, is common and often necessary for survival. In insects, symbiotic microbes often facilitate and promote the growth of hosts. Before the symbiotic collaboration can begin, however, hosts must acquire their symbionts. Sometimes, they are passed on from parents to offspring; other times, hosts must find their symbionts themselves—or face dire consequences if they fail to do so in a timely fashion, a new Frontiers in Microbiology study has shown.

Just a few hours before the Orion spacecraft crossed the sky en route to the moon on April 1, mechatronics engineer Rodrigo Trevisan Okamoto received confirmation he had been waiting for since the Artemis 2 mission was announced in 2023. The email from NASA stated that the crew of the first crewed mission to orbit the moon in half a century would carry a device developed by Okamoto and his team at Condor Instruments, a São Paulo-based startup.
