chime frb rbfloat outrigger array

‘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.
soil water organic trapped

How organic matter traps water in soil — even in the driest conditions

August 11, 2025
For the first time, Northwestern University scientists have uncovered the molecular mechanisms that enable organic matter to boost soil’s ability to retain water — even in desert-like conditions. Findings could lead to drought-resistant soils or explain how water might persist on other planets.

Asthma drug shows promise in blocking food allergy reactions

August 7, 2025
A drug already FDA-approved for asthma was found to nearly eliminate life-threatening allergic reactions to food allergens in mice — a breakthrough that could lead to new protection for millions of people living with food allergies, reports a new Northwestern Medicine study.

Clean energy is here. Getting it to EVs isn’t

August 6, 2025
Renewable energy is growing, but it’s often remote from EV charging stations. Delivering clean energy through the current grid is limited by grid congestion. Without grid upgrades, EVs will still rely on fossil fuel-generated energy. Smart, targeted upgrades could solve grid congestion to unlock EVs’ potential.
