Scientists report landmark “evolutionary double-bind” strategy to overcome treatment resistance in prostate cancer

Researchers found that radiation-resistant cancer cells are vulnerable to NK cell-mediated killing due to increased expression of specific cellular membrane proteins, creating an 'evolutionary double-bind'. The combination of radiation therapy and NK cell-based immunotherapy was more effective in suppressing both sensitive and resistan...

Prussian blue goes from pigment to purification

Scientists at the University of Chicago have created Prussian blue analogs that can achieve 99.9% lithium purification, opening up new opportunities for separating industrial waste ions from environmental streams. The unique structure of Prussian blue analogs allows for selective filtering and purification.

SMART study reveals strategic flight connections key to attracting global business and investment

A new study by SMART has identified a strong statistical association between global air connectivity and patterns of multinational corporations' investments. The research found that few layovers meant more subsidiaries, with cities having better flight connections to influential hubs outperforming those with less-connected destinations.

University of Liège scientists reveals similarities between auroras on Ganymede and Earth

Astronomers have found that the fundamental physical processes generating auroras are common to different celestial bodies, including the largest moon in the solar system. Observations of Ganymede's auroras reveal locally fragmented patches similar to those on Earth and Jupiter, suggesting a universal mechanism for aurora formation.
