California-based Aptera Motors “is rolling out the first mass-produced solar car this year,” reports the Washington Post, after successfully crowdfunding a restart of their development effort: It’s a three-wheel, ultra-aerodynamic electric vehicle covered in 34 square feet of solar cells. The car is so efficient that, on a clear day, those cells alone could provide enough energy to drive about 40…

Cosmic ray originated in cataclysmic event
Astronomers found a high energy neutrino – a cosmic ray – that apparently originated during a “tidal disruption event,” that is, when a supermassive black hole shredded a distant star. Source: https://earthsky.org/space/origin-cosmic-ray-when-black-hole-shreds-star…
Amazing gecko photos captured using X-rays from a particle accelerator
Incredibly detailed images of the intricate insides of a gecko were created using high-energy X-rays emitted by a synchrotron particle accelerator Source: https://www.newscientist.com/article/mg24933232-900-amazing-gecko-photos-captured-using-x-rays-from-a-particle-accelerator/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Merging boson stars could explain massive black hole collision and prove existence of dark matter
An international team of scientists led by the Galician Institute of High Energy Physics (IGFAE) and the University of Aveiro shows that the heaviest black hole collision ever observed, produced by the gravitational-wave GW190521, might actually be something even more mysterious: the merger of two boson stars. This would be the first evidence of the existence of these hypothetical objects, which…

We’ve spotted a neutrino blasted out by a black hole shredding a star
For the first time, researchers have detected a high-energy neutrino emitted when a black hole ripped up a star, confirming these cataclysmic events act as particle accelerators Source: https://www.newscientist.com/article/2268724-weve-spotted-a-neutrino-blasted-out-by-a-black-hole-shredding-a-star/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Scientists claim that all high-energy cosmic neutrinos are born by quasars
Scientists of the P. N. Lebedev Physical Institute of the Russian Academy of Sciences (LPI RAS), the Moscow Institute of Physics and Technology (MIPT) and the Institute for Nuclear Research of RAS (INR RAS) have studied the arrival directions of astrophysical neutrinos with energies more than a trillion electronvolts (TeV) and came to an unexpected conclusion: all of them are born…
Researchers detect galactic source of gamma rays that could produce very high-energy cosmic rays
IFIC researcher Francisco Salesa Greus, along with other members of the HAWC collaboration, have detected very high-energy photons from a galactic source that could produce cosmic rays. The detection of neutrinos through telescopes such as KM3NeT or IceCube would confirm the study. This finding has been published in The Astrophysical Journal Letters.

Could Earth’s Reversing Magnetic Poles Accelerate Climate Change?
A team of researchers from Sydney’s University of New South Wales and the South Australian Museum have investigated how the reversal of Earth’s magnetic pole about 42,000 years could have changed earth’s atmosphere. CNN reports: “Using the ancient trees we could measure, and date, the spike in atmospheric radiocarbon levels caused by the collapse of Earth’s magnetic field,” Chris Turney, a…
