Nitrogen isotope analysis reveals Southern Hemisphere waters dominated Indonesian Throughflow for 800,000 years

A research team with scientists from MARUM—Center for Marine Environmental Sciences at the University of Bremen studied the hemispheric origin of Indonesian Throughflow (ITF) and found a high Southern Hemispheric contribution over the past 800,000 […]

AI model accurately predicts the spread of wildfires in real time

Phys.org

USC researchers are developing a computational model that combines satellite data and physics-based simulations to forecast a wildfire’s path, intensity, and growth rate. If you’ve ever been evacuated from your home during a wildfire, you’ll […]

Ocean eddies move far less carbon than expected, study suggests

Phys.org

The biological carbon pump moves carbon from near the ocean’s surface to deeper regions, maintaining the upper ocean’s ability to absorb carbon from the atmosphere. One component of this system is driven by eddies, or […]

Lost millennium of Galapagos deep-sea corals linked to major Pacific climate shift

Phys.org

Scientists have discovered that deep-water corals in the Galapagos region vanished for more than 1,000 years before eventually recovering. The findings reveal that deep-water coral ecosystems may be more susceptible to climate change than previously […]

Why climate models and ocean observations diverge, and what it means for rain and drought

Phys.org

Scientific models have predicted that climate change will drive oceans in the Northern Hemisphere to warm faster than oceans in the Southern Hemisphere. However, observational data over the last 70 years show the opposite—that Southern […]

Total solar eclipse quiets seismic noise for cities within its path

Phys.org

A seismic hush fell over U.S. and Canadian cities that were in the “path of totality” during the 8 April 2024 total solar eclipse, according to new research presented at the 2026 SSA Annual Meeting.This […]

Atlantic current shows two-decade decline across four deep-ocean monitoring sites

Phys.org

A paper published in the journal Science Advances is adding to the growing body of research showing that the Atlantic Meridional Overturning Circulation (AMOC) is weakening. In this new study, instead of relying mainly on […]

Earth’s tectonic elevator hauls ancient buried microbes back to the seafloor to revive and spread

Phys.org

In subduction zones, the sites of the world’s largest earthquakes, tectonic activity may generate a “pump” that transports long-buried subseafloor microbes back toward the seafloor, according to research presented at the 2026 SSA Annual Meeting.This […]

Taiwan landslide’s hidden motion comes into focus as fiber optics track deep slip

Phys.org

Placed within a borehole drilled deep through the layers of a landslide, a fiber optic cable captured tiny, periodic stick-slip events that offer a unique glimpse at the complex movements within the landslide’s shear zone.This […]

Machine learning detects more than 60,000 earthquakes during 2025 Santorini sequence

Phys.org

The seismic crisis that gripped the Greek island of Santorini and its neighbors in 2025 contained more than 60,000 earthquakes, according to a unique machine learning study that identified the earthquakes as they occurred between […]

Early deliveries can lower product ratings by 0.2 stars, analysis of 11 million reviews finds

When it comes to package delivery, early isn’t always better. A new study published in Production and Operations Management by researchers at the University of Iowa’s Tippie College of Business finds that when a package [...]
Examining threats to monetary sovereignty in the digital era

The world is undergoing a fundamental change to how money works, and New Zealand should choose its response wisely, an Otago researcher cautions. New University of Otago—Ōtākou Whakaihu Waka research co-authored by Dr. Murat Ungor [...]
What we lose when AI does our shopping

Americans spend a remarkable amount of time shopping—more than on education, volunteering or even talking on the phone. But the way they shop is shifting dramatically, as major platforms and retailers are racing to automate [...]
