Scientists at the Event Horizon Telescope (EHT) have imaged the distant blazar J1924-2914 with unprecedented angular resolution, revealing previously unseen details of the source structure. Blazars are powerful active … Read more
Summary: Consciousness can not simply be reduced to neural activity alone, researchers say. A novel study reports the dynamics of consciousness may be understood by a newly developed conceptual and mathematical framework. source: Bar-Ilan University How do 1.4 kg of brain tissue create thoughts, feelings, mental images, and an inner world? The ability of the … Read more
The Fermi paradox, the “where is everybody?” puzzle, is a persistent question in the search for life in the universe. It asks why, if life is not exceedingly rare in the cosmos, it hasn’t shown up on our doorstep. Equally we might ask why we haven’t even heard from alien life, through radio signals or … Read more
Supercomputer simulations have probed primordial black holes and their effects on the formation of the first stars in the universe. Black holes can help stars form by seeding structures to form around them through their immense gravity. They also hinder star formation by heating the gas that falls into them. XSEDE-allocated Stampede2 simulations show these … Read more
Measurement with synchrotron-radiation monitors IOTA is equipped with synchrotron-radiation monitors at each main dipole. These stations, which use Blackfly-PGE-23S6M-C complementary metal–oxide–semiconductor (CMOS) cameras and have approximately unity magnification, are used to record direct transverse images of the beam distribution. For the OSC experiments, the M2R station was upgraded for higher resolution using two hardware improvements: … Read more
Credit: Pixabay/CC0 Public Domain UK scientists have created an “eternal engine” to keep the next generation of atomic clock ticking. Precision timing is essential for systems such as global navigation, satellite mapping, establishing the composition of exoplanets and the next generations of telecommunication. But atomic clocks are currently massive devices—weighing hundreds of kilograms—which need to … Read more
Artistic representation of chiral interactions in an ultracold cloud of atoms dressed with light. Image credit: ICFO/Scixel Researchers in Barcelona have created a peculiar new quantum simulation. The approach involves Bose-Einstein condensates – often referred to as the fifth state of matter – which have been used to study the intricate quantum properties of solid … Read more
