FDA-approved drug may finally help immunotherapy defeat rare liver cancer

Researchers found that a rare liver cancer evades immunotherapy by luring immune T cells away from the tumor and trapping them in nearby fibrous tissue. An FDA-approved drug called AMD3100 freed those T cells to attack the cancer, significantly improving the effectiveness of immu

The 'water-saving' effect of vegetation under rising CO₂ may be overestimated

Climate warming is intensifying terrestrial water scarcity and drought risks worldwide. Meanwhile, rising atmospheric CO2 reduces plant stomatal conductance—the openness of leaf pores that governs both CO2 intake and water loss—and improves water-use efficiency, which has been wi

Researchers discover why fructose doesn't satisfy hunger like glucose

A new study found that fructose and glucose may look the same on a nutrition label, but the brain treats them very differently. In mice, glucose strongly reduced activity in hunger-promoting brain cells, while fructose had a much weaker effect. High-fructose corn syrup triggered

Novel crystal strategy delivers near-perfect zero thermal expansion from 11 K to 893 K

Almost every material expands when heated. Well-known examples include railroad tracks and concrete roadways, which feature visible expansion gaps to accommodate this effect. However, thermal expansion poses a far more acute challenge for extremely precise technologies, such as l

How coworkers shape careers: Learning and competition pull in opposite directions

New research, published by the Rockwool Foundation Berlin (RFBerlin), shows that co-workers can have powerful—but opposing—effects on the careers of young workers. While some colleagues foster learning and long-term success, others may hinder career progression through direct com
