Scientists Discover Secret Weapon That Allows Pythons to Digest Bones

gizmodo.com Ellyn Lapointe 2026-02-02 15:00:40

Pythons are notorious for their eating habits. After suffocating their prey with their lithe bodies, these large snakes swallow the animal whole. Now, researchers have shed new light on the cellular mechanisms that allow them to digest entire skeletons. The study, presented July 9 at the Society for Experimental Biology Annual Conference in Belgium and published in the Journal of Experimental Biology, investigated the intestinal cells of Burmese pythons. Adult males can grow to be 10 to 16 feet

Particle Lenia Deluxe Edition

Particle Lenia Deluxe Edition. Lenia is a family of cellular automata that produces lifelike behaviors and patterns, first described in the seminal paper by Bert Wang-Chak Chan. This project is heavily inspired by the original Particle Lenia research by Alexander Mordvintsev et al., which implemented a particle-based version of Lenia in Python and JAX. Recognizing the importance of scale (number of particles) for simulation dynamics and iteration times for rapid pattern exploration, I ported th

New study offers clues about what makes someone cool

news.ycombinator.com Christina Caron 2026-02-07 20:59:49

Is there a secret sauce that helps explain why people as different as David Bowie, Samuel L. Jackson and Charli XCX all seem so self-assured and, well, cool? A new study suggests that there are six specific traits that these people tend to have in common: Cool people are largely perceived to be extroverted, hedonistic, powerful, adventurous, open and autonomous. The study, which was published on Monday in the Journal of Experimental Psychology: General, surveyed nearly 6,000 participants from

'Sticky thinking' hampers decisions in depression

news.ycombinator.com Unknown 2026-02-23 21:01:57

Though low mood is the best-known symptom of depression, indecisiveness and biased thinking are also common. But these problems, which can lead to delays in making important choices — and being more likely to make poor ones — receive less attention, write the authors of a recent paper in Emotion. Many of the theories that have been put forward to explain difficulties with decision-making are based on work suggesting that depressed people are not as responsive to rewards, or punishments, as thos

Study shows gaming can reduce stress, even the violent kind

techspot.com Alfonso Maruccia 2026-02-27 12:33:00

Editor's take: Violent video games have long been blamed as the source of many societal problems. However, an increasing number of studies continue to show that gaming poses no significant threat to society or human health, and the latest adds an interesting new perspective to the ongoing debate. A recently published study aims to dispel yet another myth about video games, showing that both violent and non-violent gaming sessions can effectively reduce stress levels.

Cancer-targeting nanoparticles are moving closer to human trials

technologyreview.com Anne Trafton 2026-03-02 08:00:00

In the original production technique, layers with different properties can be laid down by alternately exposing a particle to positively and negatively charged polymers, with extensive purification to remove excess polymer after each application. Each layer can carry therapeutics as well as molecules that help the particles find and enter cancer cells. But the process is time-consuming and would be difficult to scale up. In the new work, the researchers used a microfluidic mixing device that al

Verlet Integration and Cloth Physics Simulation (2022)

Physics simulation in games (or simply game physics) is a vast topic, and in this post we'll cover only a tiny part of it; yet certainly an interesting one! Let's understand what Verlet integration is by implementing a simple 2D cloth simulation with C++. Physics in games is always fun, isn't it?

Bottom of the Bottle French government scientists have discovered something startling about the microplastic content in glass and plastic bottles.

Drinks in glass bottles contain more microplastics than those in other container

news.ycombinator.com Unknown 2026-03-07 03:01:34

The aim of the ANSES study was to determine the level of microplastic contamination in drinks such as water, soda, iced tea, wine and beer; it also sought to establish the impact of their containers on this level. For most of the drinks studied, the level of microplastics was found to be higher in glass bottles than in other containers. For example, on average, in glass bottles of cola, lemonade, iced tea and beer, there were around 100 microplastic particles per litre. This number was five to 5

MIT brain scans suggest that using GenAI tools reduces cognitive activity

Why it matters: As the use of generative AI becomes increasingly common in education, law, politics, media, and other fields, many worry that reliance on the technology may reduce cognitive independence. A recent study from MIT strongly supports this concern, indicating that the use of digital tools significantly alters brain activity.

Scientists Discover Bizarre Signals Coming From Ice in Antarctica

Electric Cooler vs. Ice Cooler: I Went Camping With Both to See Which Is Better

I've observed that the electrification of any product brings with it a higher price for interested buyers. Case in point, everything from cars to bikes to coolers, once electrified, costs a lot more than their legacy counterparts. With that said, the benefits of a tool powered by electricity can't be understated.

Scented products cause indoor air pollution on par with car exhaust

Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications. When you hear or see the words ‘air pollution,’ you most likely think of things like factories and car exhaust. That’s pollution that is out there – outside your house.
