Antihydrogen was first produced in the lab in 1995 and in 2011 it was successfully trapped for longer periods. From there, one step at a time, physicists have been overcoming technical challenges to recently achieve a milestone: the laser cooling of antihydrogen.
A paper in Science Advances reports a new approach to simultaneously detecting the colour and polarization of light, based on the eyes of mantis shrimps.
A paper in Proceedings of the National Academy of Sciences reports on how an aquatic worm forms entangled blobs that move collectively, without the need for centralized control or even communication between the worms.
Two new maps of the sky were released in January 2021, as part of efforts to understand the distribution of ordinary matter and dark energy in the Universe.
An article in Physical Review Letters introduces a quantum algorithm for the simulation of high energy radiative processes in particle collisions, which cannot be fully captured in classical probabilistic simulations.
A paper in Communications Physics reports that cornstarch suspensions flowing down slopes form ripples like water does — but via a completely different mechanism, which involves their unusual rheology.
A Nature paper reports on the conversion of microwave-frequency quantum excitations of a superconducting qubit into photons at optical telecommunication frequencies, a step closer to realizing a working quantum transducer.
A paper in Proceedings of the National Academy of Sciences shows that the ridges on finger pads promote grip by acting as a microfluidic array that maintains optimal moisture levels and by deforming when wet to block sweat pores.
Understanding the first few minutes of the Universe has been hampered by uncertainty in the cross section of the so-called deuterium burning process. A paper in Nature reports a much-improved cross section, putting models of the early Universe on firmer footing.
In 2000, David DiVincenzo gave a set of basic criteria for building a quantum computer, which have guided research for the past 20 years. Today, despite not all the criteria having been cleared, additional complex requirements have emerged.
A report from the UK’s Science Council-supported Technician Commitment highlights the role played by technical staff in minimizing the disruption to research caused by COVID-19.
The first quantum error-correcting code was devised by Peter Shor 25 years ago. Ever since there have been numerous advances on both the theoretical and experimental fronts, and quantum error correction turned out to have unexpected applications.
