Sharks may face serious challenges in feeding themselves as ocean acidification threatens to erode their teeth, crucial tools for hunting and survival. Shark jaws carry multiple rows of teeth that continuously replace lost or damaged ones, but rapidly acidifying oceans could outpace this natural renewal, leaving predators with impaired feeding ability and potentially destabilizing marine ecosystems. Ocean acidification results from increased absorption of carbon dioxide, which lowers pH levels. Scientists project that by 2300, oceans could drop from an average pH of 8.1 to 7.3, creating profound implications for marine life. To study the effects, researchers placed 60 naturally shed…
A new study in the Colorado Rockies shows that wild bumblebees actively select flowers to meet their nutritional needs, balancing protein, fats, and carbohydrates. Over eight years, researchers tracked eight species of bees and analyzed the pollen they collected, finding significant variation in nutrient content among flower species. Protein levels ranged from 17% to 86%, and seasonal changes meant spring flowers were richer in protein while late-summer blooms contained more fats and carbohydrates. The study also revealed that coexisting bee species occupy distinct nutritional niches. Larger-bodied bees with longer tongues favored protein-rich pollen, while smaller bees with shorter tongues preferred…

Surgeons in China have successfully transplanted a genetically modified pig lung into a brain-dead human recipient, marking a first in xenotransplantation.

The Procedure and Findings The left lung came from a Chinese Bama Xiang pig with six genetic modifications aimed at reducing the risk of rejection. It was transplanted into a 39-year-old male recipient, who was brain-dead. The lung remained viable over 216…
