Magnetic nanoparticles may reveal early traces of cancer

Nanoscale magnets offer a new way to find faint, early traces of cancer in patients, according to Rice University students working on a method to capitalize on the magnets' properties. Three Rice computational and applied ...

Asteroid impact enriches certain elements in seawater

Asteroid strikes upset the environment and provide clues via the elements they leave behind. Now, University of Tsukuba researchers have linked elements that are enriched in the Cretaceous–Paleogene (KPg) boundary clays ...

Which came first: Complex life or high atmospheric oxygen?

We and all other animals wouldn't be here today if our planet didn't have a lot of oxygen in its atmosphere and oceans. But how crucial were high oxygen levels to the transition from simple, single-celled life forms to the ...

The finer details of rust

Scientists at the Vienna University of Technology have been studying the behavior of iron oxide surfaces. The atomic structure of iron oxide, which had been assumed to be well-established, turned out to be wrong. The behavior ...
