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.
food allergies

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.
power grid

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.
heart

Most U.S. adults have hearts older than their actual age

July 30, 2025
Most U.S. adults have a “heart age” several years older than their chronological age — sometimes by more than a decade. And that gap is wider among men and among those with lower incomes or education or who identify as Black or Hispanic, according to a new study led by Northwestern Medicine.
25 years of SuperAger research

What makes a SuperAger?

July 29, 2025
Over 25 of researching SuperAgers, the scientists have seen some notable lifestyle and personality differences between SuperAgers and those aging typically — such as being social and gregarious — but “it’s really what we’ve found in their brains that’s been so earth-shattering for us."
robotic limb artificial muscle

‘Bone-ified muscles’ could be robots’ next flex

July 27, 2025
A new soft actuator moves and stiffens like biological muscle. The muscles, or actuators, are constructed from low-cost, 3D-printed rubbers. Engineers integrated three actuators as ‘muscles’ into a human-sized robotic leg with 3D-printed rigid ‘bones’ and elastic ‘tendons.'
landslides

Identifying landslide threats using hydrological predictors

July 25, 2025
Current methods to predict landslides rely primarily on rainfall intensity. New model combines various water-related factors with machine learning. When applied to more than 600 landslides in California, model identified the conditions that caused 89% of the events.
