Pohřbí nová pozorování rivala temné hmoty, modifikovanou dynamiku MOND?

Modifikovaná newtonovská dynamika (MOND) se déle než čtyři desetiletí pokouší zaujmout místo životaschopné alternativy standardního kosmologického modelu s temnou hmotou. V poslední době ale dochází k vývoji, který je pro MOND spíše studenou sprchou. Temná hmota je sice stále temná, ale vesmír vysvětluje obstojně. http://www.osel.cz/13473-pohrbi-nova-pozorovani-rivala-temne-hmoty-modifikovanou-dynamiku-mond.html

Projekt Hephaistos má sedm kandidátů na nekompletní Dysonovy sféry

Pokud jsou v Mléčné dráze technologicky vyspělé civilizace, mohli bychom nalézt stopy jejich aktivity. Vědci v projektu Hephaistos pátrají po nekompletních Dysonových sférách, které by měly vyzařovat infračervené záření středních vlnových délek. Z 5 milionů zdrojů záření vybrali 7 slibných kandidátů. Jde o červené trpaslíky se zvláštním zářením. Stojí za pozornost, ať to jsou Dysonovy sféry nebo ne. http://www.osel.cz/13472-projekt-hephaistos-ma-sedm-kandidatu-na-nekompletni-dysonovy-sfery.html

Algorithms can remove bias blind spots, study shows

Algorithms are a staple of modern life. People rely on algorithmic recommendations to wade through deep catalogs and find the best movies, routes, information, products, people and investments. Because people train algorithms on their decisions – for example, algorithms that make recommendations on e-commerce and social media sites – algorithms learn and codify human biases.

This clever, “poisonous” new software is helping artists defend their work from AI

Since ChatGPT debuted in late 2022, sparking a frenzy of artificial intelligence development, artists have faced a dilemma. In order to build an audience for their work, they need to share it online. But by sharing it online, they risk having it used by tech companies, which train their AI models on the art without the artist’s consent, and without compensation.

Nano Nuclear wants to reinvent the nuclear power business—but it could take a while

Nuclear energy is responsible for 19% of U.S. electricity production, fourth in line behind natural gas, coal, and renewable energy sources such as wind. All three of those other sources seem to have a better future than the stagnant nuclear power business, which has seen only three new reactors built in the past 20 years.

This week, a two-year-old company, Nano Nuclear Energy, is expected to go public on Nasdaq with a plan to solve what ails the nuclear power business.

Where the human brain (still) has an edge over AI

In 1928, the Scottish scientist Alexander Fleming returned from a two-week vacation and realized he had made a significant oversight. In his haste to leave for his holiday, he had left a messy pile of petri dishes on his workstation. As he began to dispose of the dishes, something unusual caught his eye: a mold had formed around the bacteria in one of the petri dishes.

Upon closer examination, Fleming made a startling discovery. The mold wasn’t just growing—it was actively inhibiti

Russia is at the center of a U.N. debate over banning nuclear weapons in orbit

Russia went toe to toe with the rest of the world on Monday at the U.N. General Assembly, where officials overwhelmingly condemned Moscow’s veto last month of a measure reaffirming that nuclear weapons would not be placed in orbit.

The meeting gave member nations an opportunity to present their views on the weaponization of space and, more specifically, to respond to Russia’s unilateral veto of a joint proposal from the U.S. and Japan that was cosponsored by 65 nations. In a surpri
