‘X particle’ from the dawn of time detected inside the Large Hadron Collider

Physicists at the world’s largest atom smasher have detected a mysterious, primordial particle from the dawn of time. About 100 of the short-lived “X” particles — so named because of their unknown structures — were spotted for the first time amid trillions of other particles inside the Large Hadron Collider (LHC), the world’s largest particle … Read more

Jaw-Dropping View of The Milky Way Reveals Mysterious Structures Dangling in Space

A new image of the heart of the Milky Way is revealing mysterious structures we’ve never seen before. Taken using the ultra-sensitive MeerKAT radio telescope in South Africa, the images show nearly 1,000 strands of magnetic filaments, measuring up to 150 light-years in length, in surprisingly neat and regular arrangements.   That’s 10 times the … Read more

Abandoned SpaceX Rocket Will Crash Into The Moon Within Weeks, Scientists Say

A chunk of a SpaceX rocket that blasted off seven years ago and was abandoned in space after completing its mission will crash into the Moon in March, experts say. The rocket was deployed in 2015 to put into orbit a NASA satellite called the Deep Space Climate Observatory (DSCOVR).   Since then, the second … Read more

Can We Gauge Quantum Time of Flight?

Scientific American January 2022 Measuring the time it takes particles to travel between two points may be the best test yet for Bohmian mechanics A deceptively simple experiment that involves making precise measurements of the time it takes for a particle to go from point A to point B could cause a breakthrough in quantum … Read more

Physicists Detect Mysterious X Particles in ‘Primordial Soup’ For The First Time

A mysterious particle thought to have existed briefly just after the Big Bang has now been detected for the first time in the ‘primordial soup’. Specifically, in a medium called the quark-gluon plasma, generated in the Large Hadron Collider by colliding lead ions. There, amid the trillions of particles produced by these collisions, physicists managed … Read more

Western Australia: Is it time for the state to open up and let covid-19 in?

Western Australia, which has remained largely covid-free, has cancelled its border reopening due to omicron fears, but there may be little to gain by holding out longer Health 21 January 2022 By Alice Klein Women wearing face masks in Perth, Australia Matt Jelonek/Getty Images Western Australia, which has mostly dodged the coronavirus by sealing itself … Read more

Spaceflight makes people anemic and it doesn’t get better with time

Being in space causes the human body to destroy about 50% more red blood cells, leading to a potentially dangerous condition known as anemia. The effects persist even after astronauts return to Earth, according to a new study. The study, led by researchers at the Ottawa Hospital and the University of Ottawa in Ontario, Canada, … Read more

We’re Facing a Myopia ‘Epidemic’, Scientists Say. Here’s Why

Scientists are warning of an emerging ‘epidemic‘ of myopia or near-sightedness, having observed sharp increases in the adult onset of myopia among late baby boomers. Based on data collected from 107,442 participants in the extensive Biobank program in the UK, people born in the late 1960s are 10 percent more likely to be near-sighted than … Read more

Telltale Tsunami Sounds Could Buy More Warning Time

Editor’s Note (1/18/22): On January 15 the eruption of a volcano near Tonga triggered a far-ranging tsunami. This story about detecting tsunamis created by earthquakes is being republished in light of this event. Buoys operate as today’s state-of-the-art tsunami-detection system. Seismic data can tell officials that an underwater earthquake has occurred, but strategically placed floating … Read more

Neutral atom quantum computer made fully programmable for first time

Most quantum computers are based on superconductors or trapped ions, but an alternative approach using ordinary atoms may have advantages Technology 18 January 2022 By Alex Wilkins Quantum computers use the properties of quantum physics to perform calculations ArtemisDiana/Shutterstock A quantum computer that uses ordinary atoms to perform calculations could be a rival to more … Read more
