Simple science summaries written by AI help people understand research and trust scientists, argues a professor of communication.

From @ConversationUS: "AI-generated summaries not only improved public comprehension of science but also enhanced how people perceived scientists."

With Halloween here, we're reminded of the superstition that black cats are bad luck. 🎃

This editor can personally attest that it's not true! One of my favorite pets was a lovely black cat named Felix: smart, funny and the best companion.

@ConversationUS looks at the human biases against all black or all white animals. "As two biologists who focus on human-wildlife interactions, what we find scary is how superstitions, lore and myths can shape your subconscious – particularly biases toward the animals people are trying to conserve and protect."

"A newly discovered 450-million-year-old fossil arthropod was found entirely preserved in pyrite — aka fool’s gold."

From @popsci: "The newly named species Lomankus edgecombei boasts a leg coming out of its head called a 'great appendage' that likely helped this extinct spider-like creature live in a very hostile world."

A colossal asteroid once boiled the oceans. It also did the unexpected.

@Mashable reports: "Scientists suspect the impact left behind a monstrous crater some 297 miles (487 kilometers) wide, and created rock formations that remain exposed today in South Africa — with telltale signs from the ancient collision."

Two teenagers have once again proved an ancient math rule.

From Science News: “Some people have the impression that you have to be in academia for years and years before you can actually produce some new mathematics,” says mathematician Álvaro Lozano-Robledo of the University of Connecticut in Storrs.

Scientists say skeletal remains found in a castle well belong to figure from 800-year-old saga.

From CNN: "The 800-year-old Sverris saga, which follows the story of the real-life King Sverre Sigurdsson, includes the tossing of the body of a dead man — later known as 'Well-man' — down a well during a military raid in central Norway in 1197."

There are many factors that can affect the Earth’s spin, and no two days are ever exactly the same length. Turns out, we have something to do with that. Scientists have discovered that so-called megastructures built by humans can slow the Earth’s rotation. @sciencefocus reports: https://flip.it/O29T2t

The Atlantic Ocean's most vital ocean current is showing troubling signs of reaching a disastrous tipping point. Earlier this week, 44 oceanographers from 15 countries published an open letter calling for urgent action in the face of the weakening circulation. “We don't really consider it low probability anymore,” oceanographer Stefan Rahmstorf told @LiveScience.

It pays to recognize the tiny details around us – especially for a pair of scientists who won first place in Nikon’s 50th Small World micrography competition. Augusta University neuroscientist Bruno Cisterna and cell biologist Eric Vitriol stained cellular components to capture an image of the precise moment brain tumor cells from mice interact, which revealed disruptions in support and transport structures that lead to neurodegenerative diseases like Alzheimer's. @ScienceAlert has explains: https://flip.it/yuGoq6

A first-of-its-kind, animated map has revealed fresh secrets about a mysterious, flowering "zombie star" lurking in the remnant of a supernova that lit up Earth's skies more than 800 years ago. Today, researchers know that what was once called a “guest star” was actually a powerful supernova, or exploding star, known as SN 1181. However, its origin remained a mystery until 2021. @LiveScience has more: https://flip.it/8XzuLw

“Most antibiotics inhibit a process,” said senior study author Dr. Walid A. Houry, a professor of biochemistry at the University of Toronto. “With this approach, we are dysregulating a process, and this allows us to develop this new class of compounds that we eventually hope to get into a clinic.”

Could one type of fiber provide weight loss benefits similar to that of Ozempic? Researchers at the University of Arizona and the University of Vienna say a form that is readily found in oats and barley, called beta-glucan, may control blood sugar and assist in weight loss. It worked on mice that were fed a high-fat diet, decreasing their fat content and body weight within 18 months. @ScienceAlert has more: https://flip.it/kd4te_

Hong Kong discovers dinosaur fossils for the first time.

From @AssociatedPress: "Experts have initially confirmed the fossils were part of a large dinosaur from the Cretaceous period, about 145 million to 66 million years ago, the government said in a statement. They will need to conduct further studies to confirm the species of the dinosaur."
