A new approach to liquid-repelling surfaces

"Omniphobic" might sound like a way to describe someone who is afraid of everything, but it actually refers to a special type of surface that repels virtually any liquid. Such surfaces could potentially be used in everything ...

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 ...
