Male contraception has long lagged behind female options, but Cornell researchers may have cracked the code. A compound called JQ1 successfully halted sperm production in mice by disrupting meiosis, with full fertility restored once treatment ended. If the results translate to humans, it could mark the first practical nonhormonal contraceptive option for men.
Read article →Researchers have developed a cutting-edge technique that uses RNA “barcodes” to map how neurons connect, capturing thousands of links with single-synapse precision. The method transforms brain mapping into a sequencing task, making it faster and more scalable than traditional approaches. In mice, it revealed surprising new connections between brain cells that were previously unknown. This could open the door to earlier detection and targeted treatment of neurological diseases.
Read article →Scientists have finally uncovered the missing link in how our bodies absorb queuosine, a rare micronutrient crucial for brain health, memory, stress response, and cancer defense. For decades, researchers suspected a transporter had to exist, but it remained elusive—until now. By identifying the gene SLC35F2 as the gateway into cells, this breakthrough opens new possibilities for therapies and highlights how diet and gut microbes profoundly shape human health.
Read article →The crew of Artemis II has captured a striking new "Earthset" image, echoing the legendary Earthrise photograph taken by Apollo 8 astronauts in 1966. In the 58 years separating the two shots, Earth's climate has undergone dramatic transformation — from rising global temperatures to accelerating ice loss. The juxtaposition serves as a stark visual reminder of how much the planet has shifted since that first iconic image helped spark the modern environmental movement.
Read article →Climate change may be reshaping life on Earth faster than previously understood, with new research showing that developmental disruptions caused by climate shock can be passed down through multiple generations. The study, published in Molecular Biology and Evolution, points to inherited changes in gene regulation — not just DNA mutations — as a key driver of this accelerated process. The findings suggest evolution itself may be getting a push from a warming planet, with consequences that extend well beyond any single generation.
