Quantum gauge theories are mathematical constructs that are typically used by physicists to describe subatomic particles, their associated wave fields and the interactions between them. The dynamics outlined by these theories are difficult to compute, yet effectively emulating them in the lab could lead to valuable new insight and discoveries. …

Is Tech’s ‘Free’ Business Model For K-12 CS Education Good Or Bad?
theodp writes: The challenges of competing against free have long been noted. In the K-12 Computer Science education space, those who build a better mousetrap will still face the formidable challenge of competing with free offerings from tech giants such as Microsoft, which on Tuesday highlighted a new collaboration marrying tech-backed nonprofit Code.org’s free CS Discoveries curriculum and Microsoft OneNote for…
Whoa. It’s been 30 years since our 1st and last visit to Neptune
On today’s date – August 25, 1989 – Voyager 2 passed only 4,950 kilometers (3,000 miles) above Neptune’s north pole. It was its closest approach to any planet in its Grand Tour of the outer solar system. Source: https://earthsky.org/space/voyager-2-neptune-flyby-august-25-1989…
Would you have believed the Great Moon Hoax?
It sounds preposterous today. But – beginning on today’s date in 1835 – a newspaper claimed a famous astronomer had found life on the moon, including bat-men and unicorns. The Great Moon Hoax was widely read and believed. Source: https://earthsky.org/human-world/great-moon-hoax-august-25-1835…
Wow! What if 1 in 4 sunlike stars has an Earth?
According to a new study by astronomers, based on data from the Kepler Space Telescope, 1 in 4 sunlike stars should have a planet that’s approximately Earth-sized, orbiting in the star’s habitable zone. Source: https://earthsky.org/space/earth-like-exoplanets-orbit-one-in-four-sun-like-stars…
Snow algae thrives in some of Earth’s most extreme conditions
A new study found snow algae in tall ice structures high in the Chilean Andes. Researchers don’t entirely understand how the algae are able to bloom. Source: https://earthsky.org/earth/snow-algae-thrives-extreme-conditions…
Astronomers see a new type of pulsating star
At Palomar Observatory near San Diego, a dedicated telescope spends its nights surveying the heavens. A recent analysis of its data revealed 4 stars that change in brightness, over just minutes. Source: https://earthsky.org/space/pulsating-star-hot-subdwarf-pulsator…
IAU approves 2nd round of names for Pluto features
New Horizons provided what will be the only close-up images of Pluto many of us will see in our lifetimes. The new feature names from the International Astronomical Union recognize the mission’s forerunners in Earth and space mythology and history.

Physicists Overturn a 100-Year-Old Assumption On How Brain Cells Work
An anonymous reader quotes a report from ScienceAlert: A study published in 2017 has overturned a 100-year-old assumption on what exactly makes a neuron “fire,” posing new mechanisms behind certain neurological disorders. To understand why this is important, we need to go back to 1907 when a French neuroscientist named Louis Lapicque proposed a model to describe how the voltage of…
