Nanocrystal ‘painted’ films may someday help relieve summer heat
The rainbow palette and cooling powers of new plant-based films comes from their microscopic surface patterns of tiny crystals.
Scientists Say: Food web
All the species in an ecosystem and the feeding relationships between them get summed up with this handy picture.
Scientists Say: Virus
A virus must take over a living cell's machinery to make more viruses.
Scientists Say: PFAS
Non-stick coatings, stain-resistant cloth and other common materials leach long-lived PFAS into soil and water.
A new solar-powered gel purifies water in a flash
The unusual, fruit-inspired structure of this material provides quick filtration that could satisfy people's daily water needs.
Scientists Say: Accretion Disk
Cosmic swirls of gas, dust and plasma, accretion disks reveal the shadowy silhouettes of black holes and more.
Sea life may suffer as plastic bits alter metals in water
This interplay between plastics and metals could affect how each affects the environment — and suggests opportunities for controlling their risks.
Microplastic pollution aids viruses and prolongs their infectivity
The tiny plastic bits give these germs safe havens. That protection seems to increase as the plastic ages and breaks into ever smaller pieces.
Explainer: What is a hydrogel?
These unusual materials have a host of unusual properties. You can even make a starch-infused version in your kitchen.
Sea creatures’ fishy scent protects them from deep-sea high pressures
TMAO’s water-wrangling ability protects a critter’s critical proteins — including muscle — from crushing under deep ocean pressures.
No trees were harmed to 3-D print this piece of wood
How clever! Scientists used print-speed adjustments to control how flat, 3-D printed shapes morph into complex wooden objects.
No sun? No prob! A new process might soon grow plants in the dark
Teamwork makes green-work! Collaborating scientists came up with an electrifying farming trick that could make sunlight optional.
