A Symbiosis Between Agriculture and Solar Power
A growing population requires more food and energy, which compete for limited space…unless they don’t.
Eavesdropping on the Vibrations of Earth’s Magnetic Bubble
A NASA-funded crowdsourced science project has converted the unheard sounds resonating inside Earth’s magnetic shield into audible tracks, revealing an orchestra of whistles, wooshes, and chirps.
Carbon In, Carbon Out: Balancing the Ocean’s Books
Scientists have developed a consensus guide of standard protocols for how best to measure oceanic primary productivity, a key component in Earth’s carbon cycle.
Ice Cores Record Long-Ago Seasons in Antarctica
Researchers used ice core data to reconstruct seasonal temperatures throughout the Holocene. The results link especially hot summers with patterns in Earth’s orbit.
How to Bend Lightning with a Laser Beam
For the first time, scientists have redirected lightning using a laser beam. And that’s just the start of what’s possible.
What Electrons Can Tell Us About the Speed of Sand
A new sediment tracer uses the interactions between radiation, charge, and the Sun to uncover the hidden transport histories of sand grains.
Starry Nights Are Disappearing
Stars dim as the sky gets brighter, a result of expanding cities and bright LEDs. Simple low-tech changes can help preserve dark night skies.
Peeking at Peatlands: Satellite Data Fuel New Findings
Researchers are combining hard-to-get field measurements with satellite imagery to gain new insight into where peatlands are and how they work.
Coronal Dimmings Shine Light on Stellar CMEs
Coronal mass ejections from stars have eluded easy observation, so scientists are looking at what’s left behind.
