Being able to look up at a clear, dark sky is becoming more and more rare in the rich world. Authors, artists, and even scientists have started to express concern about what our lack of daily exposure to a dark night time sky might mean for our psyche and our sense of place in the universe. Now a team has collected photometric data at 44 sites around the world in an attempt to quantify how dark the night sky actually is at different places on the globe. So where was the darkest place surveyed? The Canary Islands.

It just so happens that the lead researcher on the project, Dr. Miguel Alarcón is from that set of islands off the west coast of Africa. The paper he and his colleagues wrote, soon to be published in The Astronomical Journal, used a series of photometers, confusing called TESS (not to be confused with the Transiting Exoplanet Survey Satellite) to try to get a baseline of how dark the night sky is throughout the world.

A new way to form self-aligned ‘color centers’ promises scalability to over 10000 qubits for applications in quantum sensing and quantum computing.

Achieving the immense promise of quantum computing requires new developments at every level, including the computing hardware itself. A Lawrence Berkeley National Laboratory (Berkeley Lab)-led international team of researchers has discovered a way to use ion beams to create long strings of “color center” qubits in diamond. Their work is detailed in the journal Applied Physics Letters.

The authors includes several from Berkeley Lab: Arun Persaud, who led the study, and Thomas Schenkel, head of the Accelerator Technology and Applied Physics (ATAP) Division’s Fusion Science & Ion Beam Technology Program, as well as Casey Christian (now with Berkeley Lab’s Physics Division), Edward Barnard of Berkeley Lab’s Molecular Foundry, and ATAP affiliate Russell E. Lake.

You and two of your friends, Judit and Gary, are on a long-awaited trip in southern India. On a leg of your journey, you find yourselves on a luxurious train ride through the Deccan Plateau, about to meander through the breathtaking Western Ghats. Before the scenery captures your attention, your friends decide to entertain themselves with a game of chess, while you continue to devour Carl Sagan’s Contact.

Something went boom in outer space and sent radioactive stardust our way, and it’s just been found at the bottom of the ocean.

To survive 7000 metres below the surface of the sea, the Yap hadal snailfish has evolved advanced mechanisms for repairing its DNA and safeguarding its proteins.

ETH Computer scientists have developed a new AI solution that enables touchscreens to sense with eight times higher resolution than current devices. Thanks to AI, their solution can infer much more precisely where fingers touch the screen.

Quickly typing a message on a smartphone sometimes results in hitting the wrong letters on the small keyboard or on other input buttons in an app. The touch sensors that detect finger input on the touch screen have not changed much since they were first released in mobile phones in the mid-2000s.
