An international team led by Prof. Dr. habil. Andrzej Niedzielski, an astronomer from the Nicolaus Copernicus University in Torun (Poland), has discovered yet another three extrasolar planets. These planets revolve around the stars that can be called elder sisters of our Sun. Source: https://phys.org/news/2021-03-elder-sisters-sun-planets.html…

World’s first video of a space-time crystal
A German-Polish research team has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of the scanning transmission X-ray microscope Maxymus at Bessy II at Helmholtz Zentrum Berlin, they were able to film the recurring periodic magnetization structure in a crystal. Published in the Physical Review Letters, the research project was a collaboration between…
Placing cosmological constraints on quantum gravity phenomenology
A description of gravity compatible with the principles of quantum mechanics has long been a widely pursued goal in physics. Existing theories of this ‘quantum gravity’ often involve mathematical corrections to Heisenberg’s Uncertainty Principle (HUP), which quantifies the inherent limits in the accuracy of any quantum measurement. These corrections arise when gravitational interactions are considered, leading to a ‘Generalized Uncertainty Principle’…

Poland Plans To Make Censoring of Social Media Accounts Illegal
Polish government officials have denounced the deactivation of Donald Trump’s social media accounts, and said a draft law being readied in Poland will make it illegal for tech companies to take similar actions there. From a report: “Algorithms or the owners of corporate giants should not decide which views are right and which are not,” wrote the prime minister, Mateusz Morawiecki,…
Microsoft, SolarWinds Face New Criticism Over Russian Breach of US Networks
After Russia’s massive breach of both government and private networks in the U.S., American intelligence officials “have expressed anger that Microsoft did not detect the attack earlier But new criticisms are also falling on SolarWinds: Some of the compromised SolarWinds software was engineered in Eastern Europe, and American investigators are now examining whether the incursion originated there, where Russian intelligence operatives…
The map of nuclear deformation takes the form of a mountain landscape
Until recently, scientists believed that only very massive nuclei could have excited zero-spin states of increased stability with a significantly deformed shape. Meanwhile, an international team of researchers from Romania, France, Italy, the USA and Poland showed in their latest article that such states also exist in much lighter nickel nuclei. Positive verification of the theoretical model used in these experiments…
Cyberpunk 2077 Bugs Hit CD Projekt
An anonymous reader shares a report: Numerous glitches reported by players as the long-awaited Cyberpunk 2077 game went live robbed creator CD Projekt of a stock surge on the back of encouraging advance-order sales figures. Poland’s biggest computer-games studio sold more than eight million copies of the futuristic title prior to its official release, mainly using higher-margin digital distribution. Excitement around…
Kilonovae: Ambushing the standard candle in its own nest
Gamma-ray bursts (GRBs) are the most luminous and explosive transient phenomena in the universe after the Big Bang. A powerful tool for characterizing and classifying GRBs to allow them to be used as tracers of the expansion history of the universe and to understand their mysterious and debated physical mechanisms has been recently presented by an international team of researchers led…
‘Extremely Aggressive’ Internet Censorship Spreads In the World’s Democracies
Researchers from the University of Michigan used their own automated censorship tracking system to collect more than 21 billion measurements over 20 months in 221 countries. They discovered that citizens in what are considered the world’s freest countries aren’t safe from internet censorship. From a press release: [Roya Ensafi, U-M assistant professor of electrical engineering and computer science who led the…
