Long-lived storage of a photonic qubit for worldwide teleportation

Scientists achieve long storage times for photonic quantum bits which break the lower bound for direct teleportation in a global quantum network.

New instrument identifies unexploded artillery shells

Society faces threats through the malicious use of chemical, biological, radiological, nuclear and/or explosive (CBRNE) materials. The detection of illicit trafficking or other criminal acts, as well as many security and safety applications, call for novel material analysis techniques and instruments. These detection systems should be non-destructive but still be able to detect and identify the threat objects, even from inside a shielding or masking enclosure. Active interrogation methods that use penetrative particle beams can reveal the presence of CBRNE materials.

Water without windows: Capturing water vapor inside an electron microscope

Scientists were able to demonstrate another way of viewing biological samples at high resolution, explains a new report.

NASA Establishes Advisory Group for National Space Council

NASA has established a new advisory group on behalf of the National Space Council that will represent the expertise, interests and perspectives of non-federal aerospace organizations to the National Space Council.

Hot vibrating gases under the electron spotlight

Scientists have studied the vibration of four gases using electron microscopy and spectroscopy. Combined with simulations, they measured the increased vibration at 1,000°C compared with room temperature. O2 and CH4 showed significant excitation, although the vibration of hot O2 was overestimated by the simulations. N2 and CO showed no increase in vibration, because of rigid bonds. The method can be used to design efficient gaseous reactions.

Scientists discover path to improving game-changing battery electrode

A comprehensive picture has now been gained of how the same chemical processes that give cathodes their high capacity are also linked to changes in atomic structure that sap performance.

Tripping the Light Fantastic

Gravitational waves usher in the era of multi-messenger astronomy.

Two holograms in one surface

A team at Caltech has figured out a way to encode more than one holographic image in a single surface without any loss of resolution. The engineering feat overturns a long-held assumption that a single surface could only project a single image regardless of the angle of illumination.
