A quantum entanglement between two physically separated ultra-cold atomic clouds

Scientists have achieved, in an experiment, quantum entanglement between two ultra-cold atomic ensembles, called Bose-Einstein condensates, spatially separated from each other.

Tailor-made synthesis of cyclic chemicals by means of enzymes

Penicillin-based antibiotics contain a five-membered hydrocarbon cycle, additionally incorporating a sulfur and a nitrogen atom. Researchers have now succeeded in selectively synthesizing this important substructure with different residues on this cycle using a biotechnological method.

Self-propelled mindless tiny robots work together to move a corral

A team of researchers at the University of Bordeaux in France has found that tiny, mindless robots are able to work together to move a corral. In their paper published in the journal Physical Review Letters, the group describes their experiments and what they found.

Processes in the atomic microcosmos are revealed

Physicists have successfully generated controlled electron pulses in the attosecond range. They used optical travelling waves that are formed by laser pulses of varying wavelengths. The movements of electrons in atoms were revealed using attosecond free-electron pulses.

3-D images of cancer cells in the body: Physicists present new method

Medical physicists at Martin Luther University Halle-Wittenberg (MLU) have developed a new method that can generate detailed three-dimensional images of the body's interior. These can be used to more closely investigate the development of cancer cells. The research group published its findings in Communication Physics.

High School Students Building NASA Hardware Recognized at Intrepid Museum Event

Students and teachers who took part in NASA’s High school students United with NASA to Create Hardware (HUNCH) program will showcase their work during an event Saturday, May 19, at the Intrepid Sea, Air & Space Museum in New York City.

NASA Awards Protective Services Contract

NASA has selected Alutiiq Advance Security Solutions, LLC of Anchorage, Alaska, to provide protective services at several agency facilities.

Two cool: A pair of patents filed on breakthrough materials for next-gen refrigerators

Scientists at the research consortium CaloriCool are closer than ever to the materials needed for a new type of refrigeration technology that is markedly more energy efficient than current gas compression systems.

Carbon-recycling system: Two-electron chemical reactions using light energy, gold

Scientists are one step closer to building a carbon-recycling system that can harvest solar energy to efficiently convert CO2 and water into liquid fuels. By optimizing many parts of the system, the researchers say, they can now drive two-electron chemical reactions, a substantial advance over one-electron reactions, which are energy inefficient.

Explanation for puzzling quantum oscillations has been found

Experiments in a system of 53 trapped atoms, presented in 2017 researchers from Harvard and MIT, revealed completely unexpected periodic oscillations in the dynamics of the interacting atoms. Now, an international team of researchers has solved the mystery of these previously inexplicable oscillations.
