Could artificially dimming the sun prevent ice melt?      (via sciencedaily.com)     Original source 

With methods of so-called geoengineering, the climate could theoretically be artificially influenced and cooled. Researchers have now investigated whether it would be possible to prevent the melting of the West Antarctic ice sheet by artificially 'dimming the sun'. The results show that artificial influence does not work without decarbonization and entails high risks.

Webb reveals colors of Earendel, most distant star ever detected      (via sciencedaily.com) 

NASA's James Webb Space Telescope has followed up on observations by the Hubble Space Telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang. Webb's NIRCam (Near-Infrared Camera) instrument reveals the star to be a massive B-type star more than twice as hot as our Sun, and about a million times more luminous.

Improving urban planning with virtual reality      (via sciencedaily.com) 

What should the city we live in look like? How do structural changes affect the people who move around it? Cartographers use virtual reality tools to explore these questions before a great deal of money is spent on building measures. Using the Unity3 game engine, they recreate scenarios in 3D where people can experience potential changes through immersion. They were able to prove that the physical reaction to this experience is measurable.

Scientists detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation of more complex carbon-based molecules. Methyl cation was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula.

Einstein and Euler put to the test at the edge of the Universe      (via sciencedaily.com)     Original source 

The cosmos is a unique laboratory for testing the laws of physics, in particular those of Euler and Einstein. Euler described the movements of celestial objects, while Einstein described the way in which celestial objects distort the Universe. Since the discovery of dark matter and the acceleration of the Universe's expansion, the validity of their equations has been put to the test: are they capable of explaining these mysterious phenomena? A team has developed the first method to find out. It considers a never-before-used measure: time distortion.
