Groundbreaking research led by a Swansea University academic has revealed a synthetic glycosystem – a sugar-coated polymer nanoparticle – that can block Covid-19 from infecting human cells, reducing infection rates by nearly 99%. The glycosystem is a specially designed particle that mimics natural sugars found on human cells. These sugars, known as polysialosides, are made of repeating units of sialic …

Off the volcanic ridges of the Eastern Pacific, deep beneath the surface where sunlight never reaches, a team of researchers has uncovered something extraordinary: a secret network of underwater caves crawling with giant tube worms—some nearly 20 inches long. The discovery, led by scientists from the Schmidt Ocean Institute in Palo Alto, California, revealed a previously unknown ecosystem lurking beneath …

Topline The majority of states along the U.S.-Canada border could have a shot at seeing the northern lights Monday night, according to the National Oceanic and Atmospheric Administration, which issued a similarly strong forecast for Tuesday night.

For beings of our size and lifespans, space is pretty big. So big, in fact, that to make it to our nearest star system you would need to factor in the fairly sizeable downside that you will die of old age before you get there. Humanity has focused on making our spaceships more speedy, as well as the possibility of …

A recent breakthrough in astronomical research, published in Nature Astronomy, has provided a detailed glimpse into the internal structure of an ancient galaxy, thanks to one of the strongest gravitational lensing events ever observed. The study, led by Seiji Fujimoto, reveals how natural magnification through gravitational lensing allows scientists to study distant galaxies with unprecedented clarity. The research, which combines …

An astronomical society journal has issued its first retraction in its 10-year history — for work done by a NASA researcher and a high school student. The duo set out to confirm an astrophysics law using calculations that assumed the law was true. The journal, Research Notes of the AAS, is published by the American Astronomical Society. It is not …

Astronomers using the Hubble Space Telescope have observed 3I/ATLAS, only the third known object from outside our Solar System to visit our neighborhood. This interstellar interloper is putting on quite a show as it approaches the Sun, revealing secrets about visitors from the depths of space. 3I/ATLAS is clearly active at 3.8 astronomical units as it approaches the Sun, showing …
