The Arab region is heating at nearly twice the global average, UN weather experts warned on Thursday, after 2024 saw unprecedented heat, destructive storms and worsening water scarcity impact some of the world’s most vulnerable communities.Continue Reading
Experiments reveal that pond frogs can eat highly venomous hornets without suffering noticeable damage, even after repeated stings. Most frogs successfully consumed hornets, including the notorious Asian giant hornet. This unusual resilience suggests that frogs may have evolved mechanisms to block the effects of venom. Their resistance could help scientistsContinue Reading
Growing energy demand means the U.S. will almost certainly have to expand its electricity grid in coming years. What’s the best way to do this? A new study by MIT researchers examines legislation introduced in Congress and identifies relative tradeoffs involving reliability, cost, and emissions, depending on the proposed approach.Continue Reading
