Triggering tumor antiviral immune response in triple negative breast cancer

A new study published in Cell reveals that RNA splicing therapeutics can activate antiviral immune pathways in triple negative breast cancers, triggering tumor cell death and signaling the body's immune response. The discovery highlights a novel mechanism for turning on the immune system in aggressive cancers.

Climate change doesn't spare the smallest

Research by University of Pennsylvania biologists Daniel Janzen and Winnie Hallwachs found that climate change has taken a toll on insects in the tropics. Insect biomass and species richness have been decomposing since the mid-1970s, with dramatic drops in moth numbers and species diversity.

Greenland melting likely increased by bacteria in sediment

Rutgers scientists found that bacteria cause sunlight-absorbing sediment to clump together and accumulate in meltwater streams on the Greenland ice sheet. This process can be incorporated into climate models for more accurate melting predictions.

New way to control electrical charge in 2D materials: Put a flake on it

Physicists at Washington University discovered a method to add electrical charge to graphene devices by layering alpha-RuCl3 flakes. This process allows for 'permanent' charge transfers without external electric fields, enabling control over the flow of electrical current.

Climate change is hurting children's diets, global study finds

A global study of 107,000 children found that higher temperatures are an equal or greater contributor to child malnutrition and low quality diets than poverty, sanitation, and education. Climate change is also associated with increased diet diversity in some regions, but this effect depends on the intensity and distribution of rainfall.
