New cooling system works on gravity instead of electricity
Scientists at KAUST in Saudi Arabia have developed a gravity-powered cooling system that extracts water from the air without using electricity.
Magnifying deep space through the “carousel lens”
Researchers at the University of San Francisco, USA, have discovered the Carousel Lens, an unprecedented galaxy alignment that bends light, aiding cosmological studies of dark matter and energy.
Scientists use magnetic nanotech to safely rewarm frozen tissues for transplant
Researchers at the Universities of California and Minnesota sprinkled magnetic nanoparticles onto frozen animal tissue and applied a varying magnetic field to safely heat them up.
Discovering the physics behind 300-year-old firefighting methods
From American Institute of Physics 26/01/24 Today, water pressure technology is ubiquitous, and any person who showers, waters a garden, or fights fires is benefiting from the technology devised to harness it. In the 17th and 18th centuries, though, a steady stream of water not punctuated by pressure drops was a major breakthrough. In 1666, […]
Mesmerising Dzhanibekov Effect
From Superinnovators 24/01/24 The Dzhanibekov Effect, also known as the tennis racket theorem, is a phenomenon in classical mechanics that occurs during the rotation of an object with three distinct momenta of inertia. When such an object, like a T-handle, wingnut or tennis racket, is tossed in the air with a spin around its intermediate […]
Chinese professor unveils ‘Harry Potter’ invisibility cloaking
From Superinnovators 04/12/23 Chinese Academy of Sciences Prof. Chu Junhao unveiled his invisibility cloak technology on 28th October at a Super Science Night event hosted by Chinese video-sharing platform Bilibili. Using a panel with a lenticular grating of tiny cylindrical convex lenses, Chu made his lower body appear invisible, while the background remained visible. This […]
Discovery of structural regularity hidden in silica glass
From Tohoku University 30/11/23 Glass is a fundamental material used in insulation and in the screens of computers and smartphones. Despite its long history, the disordered atomic structure of glass is still not fully understood by scientists. This lack of understanding makes it difficult to control glass’s structural properties and design efficient materials. A research […]
Physicists trap electrons in a 3D crystal for the first time
From Massachusetts Institute of Technology 16/11/23 Electrons move through a conducting material like commuters at the height of Manhattan rush hour. The charged particles may jostle and bump against each other, but for the most part they’re unconcerned with other electrons as they hurtle forward, each with their own energy. But when a material’s electrons […]
Which radio waves disrupt the magnetic sense in migratory birds?
From University of Oldenburg 29/08/23 While radio waves emitted by radio and television broadcasting and CB radio can disrupt the magnetic compass of migratory birds, those used in mobile communication networks do not because the frequencies are too high to affect their sense of orientation. This was the key finding of a new study published […]
