Physicists help design, build cargo X-ray scanners

(Phys.org) —Two SLAC physicists with decades of particle accelerator experience helped a Silicon Valley company design and build X-ray devices that scan cargo containers for nuclear materials and other hazards. A version ...

Building quantum states with individual silicon atoms

(Phys.org) —By introducing individual silicon atom 'defects' using a scanning tunnelling microscope, scientists at the London Centre for Nanotechnology have coupled single atoms to form quantum states.

New freeform standards to support scanning CMMs

The National Physical Laboratory (NPL), the UK's National Measurement Institute, has developed a new range of three dimensional standards for verifying freeform coordinate measurement machines (CMMs). The standard allows ...

Black Hat presentation shows iris-scanning breach

(Phys.org) -- A research team from Universidad Autonoma de Madrid and West Virginia University have troubling findings for those who think iris scanning is one of the safest methods of biometric security. Their reverse-engineered, ...

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.

Hidden beauty of the nano-cosmos

When researchers receive prizes, it is usually to honour their scientific work. However, the photographs from the scanning electron microscope, taken by Siddhartha Pathak during his postdoctoral time at Empa in Thun, Switzerland, ...

New software to end 'naked' airport scans

In the face of an outcry over so-called "naked" body scans at airports, US authorities on Wednesday announced plans for a new scanning system that eliminates "passenger-specific images."
