Universal donor immune cells

Researchers at the Weizmann Institute have developed a new form of adoptive cell transfer that overcomes limitations of current therapies. This approach uses a donor pool of immune T cells prepared in advance, which are outfitted with receptors to specifically target and destroy tumors.

Eat, prey, rain

Researchers developed a model that mimics three predator-prey modes to understand cloud-rain interactions, finding that aerosols affect cloud formation and precipitation. The study provides new insights into the complex relationships between clouds, rain, and aerosols, shedding light on climate patterns and human-induced changes.

Soft spheres settle in somewhat surprising structure

Researchers at Penn State have discovered that particles in liquids don't always settle at the bottom based on size or speed. Instead, they arrange themselves in a way that achieves the lowest energy state, often resulting in a layered structure with larger particles at the bottom and smaller ones above.
