Simulating microswimmers in nematic fluids
New research shows how control over self-propelled microswimmers could be achieved using exotic materials named 'nematic liquid crystals' - whose viscosity and elasticity can vary depending on the direction of an applied force......»»
TikTok keeps recommending live "simulated sex" videos to users
Have you seen the latest TikTok trend? You know, those livestreams.The live videos in question involve a user, typically a young, clothed woman, simulating sex. The problem with the videos is that they're being pushed to users who are not consenting.....»»
Running quantum software on a classical computer
Physicists have introduced an approach for simulating the quantum approximate optimization algorithm using a traditional computer. Instead of running the algorithm on advanced quantum processors, the new approach uses a classical machine-learning alg.....»»
DeepMind AI rivals average human competitive coder
After simulating 10 contests, with more than 5,000 participants, AlphaCode has ranks in the top 54%......»»
Study unveils a Moiré nematic phase in twisted double bilayer graphene
Moiré superlattices are systems in which two sheets of a material are placed on top of each other with a small angle misalignment, resulting in a characteristic pattern known as the Moiré pattern. In recent years, many physicists and material scien.....»»
Simulation models exercise, age effects on plaque formation in arteries
Plaque formation in the arteries carrying blood to the head and neck is a serious medical problem, potentially leading to strokes and heart attacks. In Physics of Fluids, engineers from China use fluid dynamics simulations to study the effect of exer.....»»
Study: Leidenfrost effect occurs in all three water phases: Solid, liquid, and vapor
But there's a much higher threshold of 550° C for levitation of an ice disk to occur. Slow-motion video of boiling ice, a research project of the Nature-Inspired Fluids and Interfaces Lab at Virginia Tech. Dash a few drops of water onto.....»»
An Injection of Chaos Solves a Decades-Old Fluid Mystery
In the 1960s, drillers noticed that certain fluids would firm up if they flowed too fast. Researchers have finally explained why......»»
Bioinspired veins provide structure, transport fluids in foamed polymers
Many lessons learned in life are learned from trees. Stand firm. Good things take time. Bend, don't break. But metaphors aside, our stately arboreal neighbors offer a wealth of scientific wisdom—and we have a lot to learn......»»
Simulating matter on the nanoscale with AI
In a paper published today in the scientific journal Science, DeepMind demonstrates how neural networks can be used to describe electron interactions in chemical systems more accurately than existing methods......»»
Physical features boost the efficiency of quantum simulations
Recent theoretical breakthroughs have settled two long-standing questions about the viability of simulating quantum systems on future quantum computers, overcoming challenges from complexity analyses to enable more advanced algorithms......»»
Recycling of tectonic plates a key driver of Earth"s oxygen budget
A new study co-led by a Cornell researcher has identified serpentinite—a green rock that looks a bit like snakeskin and holds fluids in its mineral structures—as a key driver of the oxygen recycling process, which helped create and maintain the s.....»»
New possibilities for life at the bottom of Earth"s ocean, and perhaps in oceans on other planets
In the strange, dark world of the ocean floor, underwater fissures, called hydrothermal vents, host complex communities of life. These vents belch scorching hot fluids into extremely cold seawater, creating the chemical forces necessary for the small.....»»
Swapping spit helps ants share metabolic labour
Ant colonies use fluids passed mouth-to-mouth to create a colony-wide metabolism, shows a study published in eLife......»»
Researchers anticipate, help prevent national security consequences of climate crises
Using novel data sets and computing systems, researchers at the Department of Energy's Oak Ridge National Laboratory are simulating how climate change affects the safety and security of the country. This research can help policy and decision makers a.....»»
Plant inspired silicone and saltwater composites have osmotically active response
A pair of researchers at the University of Illinois Urbana-Champaign have developed an artificial material that emulates the way that plants use fluids to defy gravity. In their paper published in the CellPress journal Matter, Amrita Kataruka and She.....»»
Fractured artificial rock helps crack a 54-year-old mystery
Princeton researchers have solved a 54-year-old puzzle about why certain fluids strangely slow down under pressure when flowing through porous materials, such as soils and sedimentary rocks. The findings could help improve many important processes in.....»»
Simulating chaotic interactions of three black holes
Dutch student Arend Moerman (Leiden University, the Netherlands) has defended his thesis research on the simulation of chaotic interactions of three black holes. The simulations, which he carried out together with researchers from Leiden and Oxford,.....»»
Mechanism and evolution process of supercritical fluid
Fluids are like the "blood" inside the solid Earth, playing an important role in the transportation of matter and energy. Due to the compositional difference, rocks that composed mainly of silicate and common fluids have a typically low level of misc.....»»
Researchers identify universal laws in the turbulent behavior of active fluids
Certain groupings of bacteria or cellular tissues form systems that are called active fluids. These can flow spontaneously without having to be forced from the outside, since their components are able to generate forces and move autonomously. When th.....»»
Life on Mars: simulating Red Planet base in Israeli desert
Inside a huge crater in Israel's sun-baked Negev desert, a team wearing space suits ventures forth on a mission to simulate conditions on Mars......»»
