The discovery of Nube, a faint and extended dwarf galaxy, challenges existing astrophysical models. Its unique characteristics might provide new insights into the universe and the nature of dark matter. (Artist’s concept.) Credit: SciTechDaily.comA group of astrophysicists led by Mireia Montes, a researcher at the Instituto de Astrofísica de Canarias (IAC), has discovered the largest and most diffuse galaxy recorded until now. The study has been published in the journal Astronomy & Astrophysics, and has used data…

Contains spoilers for "Fantastic Four" #17 by Ryan North, Carlos Gomez, Jesus Aburtov, and VC's Joe Caramagna In the latest "Fantastic Four" comic, Marvel's First Family is going on an archaeological dig. However, what Susan Storm finds will lead to significant questions about her potential fate. Within 2022's "Fantastic Four" series, the titular superteam's stories have leaned heavily into its science fiction elements. Each arc feels like an episode of the "Twilight Zone" that's set in the Marvel…

This illustration shows that a pair of intense THz laser pulses drives spin waves in an antiferromagnetic material, which radiate nonlinear emissions at the sum- and difference-frequencies.

Bewilderingly rapid changes are happening in the technology and reach of computer systems. There are exciting advances in artificial intelligence, in the masses of tiny interconnected devices we call the “Internet of Things” and in wireless connectivity. Unfortunately, these improvements bring potential dangers as well as benefits. To get a safe future we need to anticipate what might happen in computing and address it early. So, what do experts think will happen, and what might we do to prevent major problems?To answer…

Fliteboard, a leading manufacturer of electric hydrofoil surfboards, announced the launch of its new sub-brand FLITElab* (there’s no more info below, that asterisk is frustratingly part of the name). The announcement coincides with the launch of FLITElab*’s first product, the AMP board, which can help surfers catch a wave, both assisted and electricity-free. While Flitboard’s product line has largely served the wider electric hydrofoil board market that covers everything from lake and river surfing…

Their achievements are often forgotten or not recognized when people are choosing who inspires them, researchers have found. Most people said their family and friends,…

A research team has developed a machine learning model to address variability in quantum devices caused by material imperfections. By analyzing electron flow, the team inferred internal disorder patterns, improving predictions of quantum device performance and guiding material optimization. Credit: SciTechDaily.comA study led by the University of Oxford has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the ‘reality gap’: the…

A new study reveals that sea squirt oocytes use internal friction to undergo developmental changes post-conception, drawing an interesting parallel to a potter shaping clay. Ascidians, or sea squirts, serve as key models for understanding vertebrate development, sharing similarities with humans. Credit: SciTechDaily.comScientists examine how friction forces propel development in a marine organism.As the potter works the spinning wheel, the friction between their hands and the soft clay helps them shape it into all kinds…

Researchers at NIST studied the emission of VOCs from live Christmas trees and their interaction with ozone. They found that monoterpenes are the primary VOCs emitted, which decrease over time and react with ozone to form low levels of formaldehyde. The study concludes that Christmas trees have a minimal impact on indoor air quality for most people. Credit: SciTechDaily.comLive Christmas trees release chemicals called volatile organic compounds (VOCs).Some of those VOCs can react with ozone, a reactive gas, to produce…
