We summarize the week's scientific breakthroughs every Thursday.
- Climate
Greenland’s frozen hinterlands are bleeding worse than we thought
An inland swath of the Northeast Greenland Ice Stream is accelerating and thinning. It could contribute much more to sea level rise than estimated.
- Earth
Catastrophic solar storms may not explain shadows of radiation in trees
Tree rings record six known Miyake events — spikes in global radiation levels in the past. The sun, as long presumed, might not be the sole culprit.
- Climate
Wind turbines could help capture carbon dioxide while providing power
Turbulent wakes from wind turbines can concentrate CO2 from cities and factories, making it easier to remove the greenhouse gas from the atmosphere.
- Earth
Particles from space provide a new look inside cyclones
Cosmic rays that smash into the atmosphere make muons that are sensitive to changing air pressure inside storms.
- Climate
Here’s what happened to the Delaware-sized iceberg that broke off Antarctica
The powerful pull of currents in the Southern Ocean probably pulled apart the largest remnant of a massive iceberg that split off Antarctica in 2017.
- Earth
Landslides shaped a hidden landscape within Yellowstone
Scientists have used lasers to get a detailed view of the national park’s topography, and they’ve spotted more than a thousand landslides.
- Microbes
How fungi make potent toxins that can contaminate food
Genetically engineering Aspergillus fungi to delete certain proteins stops the production of mycotoxins that can be dangerous to human health.
- Environment
Heat waves in U.S. rivers are on the rise. Here’s why that’s a problem
In recent years, heat waves in U.S. rivers have gotten more frequent, causing trouble for fish, plants and water quality.

50 years ago, scientists found a new way to clean up oil spills
In the 1970s, researchers added chemicals to the list of oil spill cleanup methods. Soon, they may add microbes.
- Animals
Tree-climbing carnivores called fishers are back in Washington’s forests
Thanks to a 14-year reintroduction effort, fishers, or “tree wolverines,” are once again climbing and hunting in Washington’s forests after fur trapping and habitat loss wiped them out.
- Climate
Climate change could turn some blue lakes to green or brown
As temperatures rise, more than 1 in 10 of the world’s blue lakes could change color, reflecting holistic shifts in lake ecosystems.
- Earth
50 years ago, scientists dug into Pangaea’s past lives
In 1972, scientists wondered whether Pangaea was Earth’s only supercontinent. Fifty years later, we know it wasn’t the first and it won’t be the last.
