Wind turbines could help capture carbon dioxide while providing power
Wind turbines could offer a double whammy in the fight against climate change. Besides harnessing wind to generate clean energy, turbines may help to funnel carbon dioxide to systems that pull the greenhouse gas out of the air (SN: 8/10/21). Researchers say their simulations show that wind turbines can drag dirty air from above a […]
Why dandelion seeds are so good at spreading widely
You don’t need a dandelion to know which way the wind blows. But it can help. On any given dandelion, some seeds are destined to go north, while others are fated to fly east, south or west, and every direction in between. In effect, each dandelion seed is programmed to release for a wind coming […]
Sound waves make stretchy connections for flexible electronics
Zapping liquid metal droplets with ultrasound offers a new way to make wiring for stretchy, bendy electronics. The technique, described in the Nov. 11 Science, adds a new approach to the toolbox for researchers developing circuitry for medical sensors that attach to the skin, wearable electronics and other applications where rigid circuit electronics are less […]

Muons from cosmic rays provide a new look inside cyclones
Particles raining down from space offer 3-D views inside swirling tropical storms. Muons created from cosmic rays that smash into Earth’s upper atmosphere have revealed the inner workings of cyclones over Japan, researchers report October 6 in Scientific Reports. The new imaging approach could lead to a better understanding of storms, the researchers say, and […]
Protons may be stretchier than physics predicts
Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New experiments seem to show that the quarks respond more than expected to an electric field pulling on them, physicist Nikolaos Sparveris and colleagues […]
