Organic aerosols in remote areas have shorter lives than scientists assumed
Scientists find the lifetime of organic aerosols in the upper atmosphere is on the order of 10 days, far shorter than scientists previously assumed.

NASA Solves How a Jupiter Jet Stream Shifts into Reverse
Speeding through the atmosphere high above Jupiter’s equator is an east–west jet stream that reverses course on a schedule almost as predictable as a Tokyo train’s. Now, a NASA-led team has identified which type of wave forces this jet to change direction.

High-resolution climate models present alarming new projections for U.S.
Researchers have developed new, high-resolution climate models that may help policymakers mitigate the effects of climate change at a local level.
Lava-filled blocks on Venus may indicate geological activity
A global view of some well-known deformation features on Venus’s surface may indicate it’s capable of crustal motion, and that motion might even be happening today, scientists report.
Proteins in shark teeth could hint at what they eat
Certain molecules found in shark teeth proteins could tell scientists how the predators are connected to other animals in the food web, according to new research.
Coastal erosion threatens archaeological sites along Greenland’s fjords
Hundreds of archaeology sites lie along the shores of Greenland’s fjords and coasts, revealing the entirety of the country’s ancestral cultures from as many as four thousand years ago. Coastal erosion, however, may soon drop many of those ancestral links into the ocean.
Subterranean Serendipity: Scientists stumble upon a new way to sample magma
Scientists have never directly observed magma beneath the Earth’s surface. But thanks to the discovery of easily accessible magma chambers, it may now be possible, report scientists at the 2017 American Geophysical Union Fall Meeting in New Orleans.

Earwax like ice cores: Unlocking the past hidden in whale earplugs
Data collectors are cruising around oceans worldwide, following blooms of productivity and accumulating decades of information—all from earwax. New research shows whale earplugs provide records of the animals’ movements and diets over the course of their long lives.
The continental U.S. is experiencing more flooding, and earlier in the year
The frequency of flooding in the continental U.S. is increasing, and seasonality of floods is shifting, according to new research.

Scientists capture Earth’s “hum” on ocean floor
Researchers have successfully quantified Earth’s vibrational “hum” using seismic instruments on the bottom of the ocean. A new study determined at the ocean bottom the frequencies at which the Earth naturally vibrates, and confirmed the viability of using ocean instruments to study the phenomenon.
