Crowding can speed up enzyme reactions—until protein droplets become too packed

Our cells are a hotbed of activity, with reactions churning away to keep us alive. But the cytoplasm, where many metabolic reactions take place, is not uniform. Instead, proteins and other molecules cluster together into membraneless compartments, creating distinct, crowded micro
Our cells are a hotbed of activity, with reactions churning away to keep us alive. But the cytoplasm, where many metabolic reactions take place, is not uniform. Instead, proteins and other molecules cluster together into membraneless compartments, creating distinct, crowded microenvironments for reactions.

Television gains ground in streaming platform era, study shows
A University of Alicante (UA) study of 325 fiction series released in Spain between 2020 and 2024 has concluded that video-on-demand (VOD) platforms have not replaced traditional television. Instead, the two distribution models are developing new ways of collaborating and sharing

New calculations reveal hidden pathways that let chemical reactions produce different products
Chemical reactions are often understood as molecules crossing a high-energy saddle point, known as a transition state, before following a downhill pathway toward a product. Conventional quantum chemical calculations typically trace this single pathway to determine how a reaction

Asteroids venturing near white dwarfs don't break directly into dust, study reveals
When asteroids travel too close to white dwarfs, the dense remnants of stars that have exhausted their nuclear fuel, powerful gravitational forces can tear them apart. However, new research from Planetary Science Institute (PSI) suggests that these asteroids don't immediately bre

Measuring multiple reactions on a single electrode with extraordinary sensitivity
A reaction on a single electrode can tell scientists a remarkable amount about the chemical nature and number of analytes involved. The challenge comes when they want to distinguish many reactions on the same electrode. After more than a decade of trying to overcome that limitati
