Facelifts can sag. Botox is temporary. But modern science has a new way to return youth to weathered faces: the rock abrasion tool (RAT). If your dermatologist hasnt heard of it, ask your local Mars scientist.
Billions of years of exposure to the sun, atmosphere and extremely fine Martian dust has given Mars rocks a weathered "rind," or exterior layer. The RAT, part of the science-instrument package carried by the two Mars rovers, Spirit and Opportunity, uses a diamond-tipped robotic grinding tool to scrape away this weathered exterior, revealing a fresh surface.
"Clearing away the dust and a weathered layer gives the science instruments access to the part of the rock that hasnt changed since it was formed billions of years ago," says Cornell University alumnus Paul Bartlett. An employee of New York engineering firm Honeybee Robotics, Bartlett has been working on the RAT since the first concept drawings from Cornell professor of astronomy Steven Squyres arrived in his fax machine three years ago.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
