Beetles under climate stress lay larger male eggs: Wolbachia infection drives adaptive reproduction strategy in response to rising temperature and CO₂

Researchers found that azuki bean beetles infected with Wolbachia bacteria produce larger eggs yielding exclusively male offspring when exposed to elevated temperature and carbon dioxide. This adaptive reproduction strategy enhances the survivability of their offspring.

Education exports help offset U.S. trade deficit—but new tariff and visa policies threaten gains

A new study finds that US universities rely heavily on international students to offset the country's trade deficit, but new tariff and visa policies may reverse this trend. The researchers estimate that a 25% drop in Chinese students from 2017-18 to 2018-19 resulted in $1.1 billion in revenue loss for US universities.
