Hidden Waves Wash Fluid Through The Brain While You Sleep : ScienceAlert

While you're peacefully dreaming, your brain is taking care of a few important maintenance tasks. A new study reveals more about the process that ejects waste material from the brain while we're snoozing.The brain produces these waste substances as it expends energy and sucks up nutrients during the day. Taking out the trash is the job of the glymphatic system, however we don't yet have a full picture of how this network of drainage channels functions.Researchers from Washington University in St Louis observed neurons…

Organoids made from amniotic fluid will tell us how fetuses develop

Researchers have known for decades that amniotic fluid holds fetal cells. That’s what allows doctors to diagnose conditions like Down syndrome and sickle-cell disease before birth via amniocentesis, in which a needle is used to take a sample of the fluid. The vast majority of these cells, 95% or more, are dead cells sloughed off by the fetus, says Mattia Gerli, a stem cell biologist at University College London and an author of a paper on the work published in Nature Medicine today. But what the researchers homed in on…

AMD Fluid Motion Frames (AFMF) is here to make games smoother

AMD has released a new Adrenalin Edition GPU driver. It carries version 24.1.1 and brings two big features, AMD Fluid Motion Frames (AFMF) and AMD Video Upscaling. What is AMD Fluid Motion Frames (AFMF)? AMD Fluid Motion Frames is a frame-generation feature. It generates frames in games to increase the frame rates to offer a smoother gaming performance. According to the company, when coupled with AMD FidelityFX Super Resolution 2 (FSR 2), AFMF increases the frame rates up to 97% on average in games at 1080p resolution,…

Asus talks about AMD Fluid Motion Frames for ROG Ally in an update to Armoury Crate SE

In a new post on X (previously known as Twitter), Asus has announced that it has started rolling out an update to Armoury Crate SE (ACSE) for the ROG Ally. Along with that, the company has also given an update about the AMD Fluid Motion Frames (AFMF) feature for the handheld gaming console. Starting with the update to ACSE, it bumps the software’s version to 1.4.10 and brings four significant improvements. Armoury Crate SE v1.4.10 for ROG Ally The biggest improvement is the addition of the Manual mode to the Operating…

Trailing-edge fringes could lead to low-noise fluid machinery

Credit: Pixabay/CC0 Public Domain Owls are fascinating creatures that can fly silently through some of the quietest places. Their wings make no noise while flying, enabling them to accurately locate their prey using their exceptional hearing ability while remaining undetected. This unique ability depends on many factors and has long been a hot research subject.…

Ax-3 Mission Launch Delayed – Space Station Crew Harvests Plants and Conducts Fluid Research

The orbital residents aboard the International Space Station also studied future piloting techniques and fluid physics rounding out the research schedule.NASA astronauts Loral O’Hara and Jasmin Moghbeli joined Commander Andreas…

Windshield Washer Fluid Is an Unexpected Source of Vehicle Emissions

In a study published in the ACS’ Environmental Science & Technology journal, researchers reported that windshield washer fluid alcohols represent a higher fraction of vehicle emissions than previously estimated. This source of pollution remains constant even as more drivers switch from gas to electric vehicles.A research study reveals that alcohols from windshield washer fluid contribute more significantly to vehicle emissions than previously thought. This holds true even with the increased adoption of electric…

Researchers determine quantitative composition of ultrahigh-pressure fluid in deep subduction zones

Credit: Prof. Xiao’s group In a study published in Proceedings of the National Academy of Sciences, Prof. Xiao Yilin's group from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) quantitatively determined, for the first time, the chemical composition of supercritical fluids in deep subduction zones. Through 3D imaging…

Physics Experiment Inspired by Earth’s Core Leads to Groundbreaking Discovery in Fluid Flow Turbulence

Physicists have discovered a new aspect of turbulent convection, demonstrating that it can cause a freely moving solid within the fluid to rotate in two directions, sometimes switching due to turbulence. This research, which has implications for understanding fluid flows from Earth’s core to boiling water, also highlights the key role thermal convection might play within the Earth and the potential for turbulence to be controlled by interaction with solids.Turbulent flows take on a surprising spin in an experiment…
