A new look at Apollo samples supports ancient impact theory

New investigations of lunar samples collected during the Apollo missions have revealed origins from beyond the Earth-Moon system, supporting a hypothesis of ancient cataclysmic bombardment for both worlds.

Helium ions reveal how viruses attack bacteria

An interdisciplinary research consortium from the Nanoscience Center at University of Jyvaskyla in Finland (group leaders Dr. Lotta-Riina Sundberg and Prof. Ilari Maasilta) has found that bacteria and viruses can be imaged ...

Researcher hunts DNA on Mars

Astrobiologist alumna Alexandra Pontefract, PhD'13 (Geology), knows finding DNA on the Red Planet will be no easy feat. But it is possible. What's more, if DNA is found, it's not far-fetched to think it would be proof of ...

Amnesty: Satellite images show Aleppo devastation (Update)

Satellite images have laid bare the suffering inflicted on Syria's largest city, a London-based rights group said Wednesday, cataloguing hundreds of damaged or destroyed houses and more than 1,000 roadblocks.

How ion bombardment reshapes metal surfaces

To modify a metal surface at the scale of atoms and molecules — for instance to refine the wiring in computer chips or the reflective silver in optical components — manufacturers shower it with ions. While the process ...

Nano-hillocks: Of mountains and craters

In the field of nanotechnology, electrically-charged particles are frequently used as tools for surface modification. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the TU Vienna were at last able to reconcile ...

Image: A storm of comets around star Eta Corvi

(Phys.org) -- This artist's conception illustrates a storm of comets around a star near our own, called Eta Corvi. Evidence for this barrage comes from NASA's Spitzer Space Telescope, whose infrared detectors picked up indications ...
