Two steps ahead—neutrons help explore future HIV treatments

Human immunodeficiency virus (HIV) is a quick learner. As fast as researchers get effective anti-viral drugs into clinical trials, the virus evolves, deploying potent resistance mutations that render the medicine useless ...

New approach yields high-purity radium for medical applications

Producing radium isotopes to treat cancer could get easier. Researchers developed a method to recover medical radium isotopes. The process begins with the dissolved proton-irradiated thorium target solution. The process then ...

Similar-looking ridges on Mars have diverse origins

Thin, blade-like walls, some as tall as a 16-story building, dominate a previously undocumented network of intersecting ridges on Mars, found in images from NASA's Mars Reconnaissance Orbiter.

Rip in crust drives undersea volcanism, says study

Scientists analyzing a volcanic eruption at a mid-ocean ridge under the Pacific have come up with a somewhat contrarian explanation for what initiated it. Many scientists say undersea volcanism is triggered mainly by upwelling ...
