Under the dome: Fears Pacific nuclear 'coffin' is leaking

As nuclear explosions go, the US "Cactus" bomb test in May 1958 was relatively small—but it has left a lasting legacy for the Marshall Islands in a dome-shaped radioactive dump.

Comet inspires chemistry for making breathable oxygen on Mars

Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason—we humans need molecular oxygen (O2) to breathe, and space is essentially devoid of it. Even on other planets with ...

Scientists discover ancient seawater preserved from the last Ice Age

Twenty thousand years ago, in the thick of an Ice Age, Earth looked very different. Because water was locked up in glaciers hundreds of feet thick, which stretched down over Chicago and New York City, the ocean was smaller—shorelines ...

Solving geothermal energy's earthquake problem

On a November afternoon in 2017, a magnitude 5.5 earthquake shook Pohang, South Korea, injuring dozens and forcing more than 1,700 of the city's residents into emergency housing. Research now shows that development of a geothermal ...

Adding a carbon atom transforms 2-D semiconducting material

A technique that introduces carbon-hydrogen molecules into a single atomic layer of the semiconducting material tungsten disulfide dramatically changes the electronic properties of the material, according to Penn State researchers ...

Hubble spies curious galaxy moving a little closer

This Hubble image stars Messier 90, a beautiful spiral galaxy located roughly 60 million light-years from the Milky Way in the constellation of Virgo (the Virgin). The galaxy is part of the Virgo Cluster, a gathering of galaxies ...

Two decades of tie-ups and break-ups among EU carmakers

French auto giant Renault and Italian-US counterpart Fiat Chrysler are planning to announce an alliance, further reshaping Europe's auto sector which has already witnessed two decades of takeovers, alliances and break-ups.

WWII researcher: Sea wreck must be plane of US MIA pilot

Wreckage on the ocean floor near a Japanese island must be from a fighter-bomber that crashed in 1945 with an American pilot who is still listed as missing in action, according to a World War II researcher who recently visited ...

NASA's Mars 2020 mission drops in on Death Valley

On a test flight in Death Valley, California, an Airbus helicopter carried an engineering model of the Lander Vision System (LVS) that will help guide NASA's next Mars mission to a safe touchdown on the Red Planet. During ...

World celebrates centenary of confirmation of relativity

Celebrations are underway across the globe to commemorate 100 years since a UK-led expedition confirmed Einstein's general theory of relativity. The theory fundamentally changed our understanding of physics and astronomy, ...

Sea dragons captivate visitors at California aquarium

At first glance, it looks like a branch of kelp, but then an eye moves among its leafy appendages, and ridges of tiny, translucent fins start to flutter, sending the creature gliding through the water like something from ...
