Who says pollution clean-up has to pay for itself?

In a world searching for more sustainable ways to manage waste, the promise of turning "trash into treasure" is hard to ignore. Take nitrate pollution, for example. Every year, nitrogen fertilizers help feed billions of people. But not all of that nitrogen stays where it is

In biology of cells, octopus has another trick up its sleeve

The octopus is a biological oddity. It can use tools, open jars, and its complex nervous system supports as many neurons as a small primate. Now Harvard biologists have discovered a mysterious distinction in octopuses' core biology: Some octopuses have an unusual adaptation in

Two attosecond flashes capture electrons in motion

Electronic motion sets the stage for virtually every light-induced process in nature, from the first step of a chemical reaction to the flow of charge in a solid. Yet these processes unfold so rapidly that they can be observed only with flashes of light lasting a few hundred

ESCAPADE's cameras capture Earth and moon

In November 2025, NASA's Mars-bound ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft launched from Cape Canaveral with special cargo on board: two camera systems designed and built by faculty and students at NAU, with support from the University of

Black hole 'blast' reaches 300,000 light-years

A team of researchers has discovered that winds generated by supermassive black holes are 100 times more powerful than previously thought, carrying energy across distances of approximately 300,000 light-years. The discovery demonstrates that these explosive winds affect the

Why the hepatitis E virus cannot infect mice

Many viruses can infect both humans and animals, including hepatitis E virus. This virus is often transmitted to humans via contaminated meat products, such as by ingesting raw or undercooked pork or wild game. However, mouse liver cells are not a suitable host for hepatitis E

A successful, sustainable catalyst for ethanol dehydrogenation

Ethanol is an alcohol used in a vast number of industrial and household applications. When dehydrogenated—in this case, stripped of some of its hydrogen atoms—it yields another important compound: acetaldehyde, which is used to make resins, dyes, perfumes and synthetic flavors,

Your gut may help your brain decide what to remember

Signals traveling from the gut to the brain may help turn meals into lasting memories. Rats showed stronger memory activity after consuming nutritious foods, but not after drinking sweet liquids with little or no nutritional value. Blocking the vagus nerve erased this effect

Why are so many dead bumblebees appearing on sidewalks?

Bumblebees naturally have short lives, but extreme heat and human activity are making survival harder. Pesticides can poison bees or destroy the flowers they depend on, while habitat loss leaves them with fewer safe places to live and feed. Protecting native plants and using

New twist on the Einstein problem reveals unexpected physics

A shape that captured worldwide attention for solving a decades-old mathematical puzzle has returned to the spotlight. While the shape's properties allowed it to solve previous puzzles, little is known about its other associated properties, creating opportunities for further
