Phys.org / Ancient charcoal reveals evidence of wildfires near the South Pole

A journey back in time to the Late Cretaceous: A swampy rainforest with conifers and tree ferns stretches as far as the eye can see, dinosaurs roam through the misty wetlands, and the climate is mild and warm. The average ...

Phys.org / New model measures economic risks solar storms pose to US power grid

In 1967, a solar storm nearly triggered World War III by jamming early-warning radar systems in the United States, causing U.S. leaders to think the Soviet Union was responsible. Though society averted catastrophe thanks ...

Phys.org / Two-color X-ray pulses capture the same nanoparticle at two moments in time

One big dream of ultrafast science has been to watch changes in nanoparticles or biomolecules on their natural timescale. Experimentally, this can be realized by taking two snapshots of the same object only femtoseconds apart. ...

Phys.org / Six unusual structures identified at Earth's core-mantle boundary with the help of deep learning

Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study ...
