No-sort plastic recycling is near

September 2, 2025
Northwestern University chemists have introduced a new plastic upcycling process that can drastically reduce — or perhaps even fully bypass — the laborious chore of pre-sorting mixed plastic waste.

For bees, diet isn’t one-size-fits-all

August 26, 2025
New study tracked eight bumble bee species in the wild across eight years. Bee species occupy two distinct diet groups: one prefers protein and another prefers fat and carbs.
NIH Baby Toolbox

A new tool to track infant development, starting at just 16 days old

August 25, 2025
Developmental scientists and medical social science experts at Northwestern University have spearheaded the creation of the most recent NIH Toolbox, providing the newest nationally standardized assessment of cognitive, language, motor and social-emotional skill development in infants aged 16 days to 42 months.

‘Root beer FLOAT’ burst’s home is located with extraordinary precision

August 21, 2025
Newly detected fast radio burst (FRB) is one of the brightest ever observed. Astronomers used the CHIME telescope array to triangulate the burst’s location. FRB traced to the outskirts of a star-forming region in a nearby galaxy using powerful optical telescopes. Location is accurate within just 42 light years, the most precise localization yet for a non-repeating FRB.
A still from a visualization of the star's likely explosion

First-of-its-kind supernova reveals inner workings of a dying star

August 20, 2025
For the first time, astrophysicists detected a supernova embedded in a wind rich with silicon, sulfur and argon. Observations suggest the massive star lost its outer hydrogen and helium layers long before exploding. Discovery offers direct evidence of the long-theorized inner shell structure of massive stars.

Clean hydrogen’s iridium problem? Solved in an afternoon

August 19, 2025
For decades, researchers around the world have searched for alternatives to iridium, an extremely rare, incredibly expensive metal used in the production of clean hydrogen fuels. New material rivals iridium for water splitting reaction at a fraction of the cost.
