A new study suggests that ocean acidification may erode shark teeth, potentially undermining their ability to feed and threatening marine ecosystem stability. Sharks naturally lose and replace teeth in rows, but more acidic oceans could accelerate tooth damage faster than replacement rates allow. Researchers tested 60 naturally shed teeth from blacktip reef sharks in tanks simulating current ocean pH (8.1) and projected future levels (7.3). After eight weeks, the teeth in acidic water suffered double the damage, including root corrosion and altered serrations. Lead author Maximilian Baum, from Heinrich Heine University, warned that this could hinder sharks’ hunting efficiency, especially…

Wild bumblebees carefully choose different flowers to meet their nutritional needs, according to a new study. Over eight years, researchers in the Colorado Rockies observed eight species of wild bumblebees and mapped their pollen-based diets. By analyzing pollen samples in the lab, the team measured protein, fat, and carbohydrate levels, discovering that bees adjust their diets to match seasonal changes in nutrient availability. Protein levels in flowers varied widely, ranging from just 17% to as much as 86%. Spring flowers tended to offer protein-rich pollen, while late-summer blooms provided more fats and carbohydrates. Larger-bodied bees with long tongues preferred protein-heavy…

Heavy Tariffs Threaten Indian Trade The United States has introduced 50% tariffs on Indian goods, a measure expected to hit exports of clothing, jewelry, seafood, and other products. The steep duties are seen as a major setback for India’s export-driven industries and could strain trade relations between New Delhi and Washington. Call for Homegrown Production and Pride Prime Minister Narendra Modi has responded with an appeal for greater reliance on domestic products. Speaking during Independence Day celebrations, he urged citizens and small business owners to showcase “Made in India” goods, stressing that self-reliance should come from national pride rather than…

Surgeons in China have successfully transplanted a genetically modified pig lung into a brain-dead human recipient, marking the first reported case of its kind. The transplanted lung functioned for nine days without triggering hyperacute rejection or infection, though it did eventually show fluid buildup and progressive antibody-driven damage. The procedure, described in Nature Medicine, involved a lung from a Chinese Bama Xiang pig with six genetic modifications to reduce immune rejection. Challenges and Future Prospects Experts caution that while this represents an important step in xenotransplantation research, pig lungs face unique hurdles compared with other organs like kidneys and hearts.…
