When it comes to compounding natural hazards like landslides, wildfires, flooding and extreme heat, where you live makes all the difference. New research from Portland State University underscores this disproportionate reality, finding that in Portland, the areas most vulnerable to multiple climate hazards are historically underinvested neighborhoods marked by lower median incomes, lower education levels and higher racial diversity.

A flash of light lasting a fraction of a millisecond could help create better materials for solar energy. Researchers used ultra-fast heating at rates of up to 10 million degrees Celsius per second to rearrange the atoms inside a semiconductor, producing a version that generated up to 50 times more electrical current from light than the same material in its ordinary form. Because the flash heats only the semiconductor coating and not the surface it sits on, the method works on transparent conducting glass, the see-through conducting surface used in touchscreens and solar cells, which conventional furnaces would ruin. The method could eventually help improve solar technologies and other advanced electronic devices.

What if the secret to drought-resistant crops isn't how much water plants use, but when they use it? A new study identifies a daily window that could help breeders develop tomatoes that better withstand drought without sacrificing yield.

As record-breaking heat grips communities worldwide and Australia prepares for an intense El Niño summer, new research provides the first global review linking high temperatures and heatwaves to poorer mental health in children and young people.
