Recently a well-respected UI consulting firm (the Nielsen Norman Group) published their analysis of academic studies on the question of whether Dark Mode or Light Mode was better for reading? Cosima Piepenbrock and her colleagues at the Institut für Experimentelle Psychologie in Düsseldorf, Germany studied two groups of adults with normal (or corrected-to-normal) vision: young adults (18 to 33 years old)…

Researchers discover a unique orbital texture in single-layer of 3-D material
New physical behavior, such as Mott insulating behavior, unconventional superconductivity and quantum spin liquid behavior, occurs when electrons inside a material interact with each other. When electrons are confined to lower dimensions such as 2-D planes, these effects can become even stronger. …
A new twist on quantum communication in fiber
New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting implications for secure data transfer across optical fiber networks. The team have demonstrated that multiple quantum patterns of twisted light can be transmitted across a conventional fiber link that, paradoxically, supports only one pattern. The implication…
3D TV Tells You Everything About This Decade’s Tech
You don’t need special glasses to see what it looks like when smart people run out of ideas. From a column: The breakout hit of the Consumer Electronics Show in 2010 was a television set. Hard to believe now, maybe, but it’s true; for one shining moment, the Toshiba Cell TV was the most exciting new thing in tech. Its name…
Get ready for the Venus-Saturn conjunction
Venus and Jupiter had a spectacular conjunction last month. Soon, Saturn and Venus will meet in the west after sunset. Guy Ottewell offers insights and charts to prepare you for this encounter between worlds. Source: https://earthsky.org/astronomy-essentials/venus-saturn-conjuction-12-10-2019-ottewell…
Adiabatic shortcuts: Short and sweet in the quantum world
Completing a task slowly and carefully may provide us with a high-quality product. It can be summed up by the popular adage “easy does it.” But what if a high price has to be paid for slowness? Time is a scarce resource and, what is more, a good result is not guaranteed, since we may be easily disturbed or interrupted by…
Elon Musk Unveils ‘Cybertruck’ Electric Pickup Truck
At an event in Los Angeles, California, Elon Musk unveiled the company’s first electric pickup truck, called the Cybertruck. The design is unlike any other vehicle on the road today, consisting of a stainless steel alloy body with sharp corners and tall rugged wheels. The truck will come in three versions with 250-500 miles of range, depending on the model. It…
Extending electron paramagnetic resonance (EPR) spectroscopy to nanoliter volume protein single crystals
Biochemists can use electron paramagnetic resonance (EPR) on protein single crystals to determine the ultimate electronic structure of paramagnetic protein intermediates and investigate the relative magnetic tensor to a molecular structure. The method is, however, withheld by typical protein crystal dimensions (0.05 to 0.3 mm) that do not provide sufficient signal intensity during protein crystallography. In a new study on Science…
The whole picture of a distant supercluster in three dimensions
Using the Subaru Telescope and Gemini-North Telescope, a team of astronomers has revealed that the supercluster CL1604, a distant supercluster located about 7.3 billion light-years away, is a large-scale 3-D structure extending over about 160 million light-years in the north-south direction. This is more than two times more extended than previously known. Until now, astronomers saw merely the “tip of the…
Some Corals Grow After ‘Fatal’ Warming
An anonymous reader quotes a report from Phys.Org: For the first time ever, scientists have found corals that were thought to have been killed by heat stress have recovered, a glimmer of hope for the world’s climate change-threatened reefs. The chance discovery, made by Diego K. Kersting from the Freie University of Berlin and the University of Barcelona during diving expeditions…
