Nonreciprocal interactions go nonlinear

Matter and energy from Science Daily Feed - Thu, 07/25/2024 - 12:47pm
Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.

Researchers explore the interplay between high-affinity DNA and carbon nanotubes

Matter and energy from Science Daily Feed - Thu, 07/25/2024 - 12:47pm
Single-walled carbon nanotubes (SWCNTs) hold promise for biomedicine and nanoelectronics, yet the functionalization with single-stranded DNA (ssDNA) remains a challenge. Researchers using high-affinity ssDNA sequences identified through high-throughput selection. They demonstrated the effectivity and stability of these constructs using molecular dynamics simulations. Machine-learning models were used to accurately predict patterns that govern ssDNA-SWCNT binding affinity. These findings provide valuable insights into the interactions between ssDNA and SWCNTs.

Artificial blood vessels could improve heart bypass outcomes

Matter and energy from Science Daily Feed - Thu, 07/25/2024 - 12:47pm
3D-printed blood vessels, which closely mimic the properties of human veins, could transform the treatment of cardiovascular diseases. Strong, flexible, gel-like tubes -- created using a novel 3D printing technology -- could improve outcomes for heart bypass patients by replacing the human and synthetic veins currently used in surgery to re-route blood flow, experts say.

Space-trekking muscle tests drugs for microgravity-induced muscle impairment

Space and time from Science Daily Feed - Thu, 07/25/2024 - 12:47pm
A gentle rumble ran under a researcher's feet as a rocket carrying her research -- live, human muscle cells grown on scaffolds fixed on tiny chips -- lifted off, climbed, and disappeared into the sky to the International Space Station National Laboratory. These chips would help her better understand muscle impairment, often seen in astronauts and older adults, and test drugs to counter the condition.

A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine

Matter and energy from Science Daily Feed - Thu, 07/25/2024 - 12:47pm
Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.

Next-gen cooling system to help data centers become more energy efficient

Computers and Math from Science Daily Feed - Thu, 07/25/2024 - 12:46pm
Artificial intelligence (AI) is hot right now. Also hot: the data centers that power the technology. And keeping those centers cool requires a tremendous amount of energy. The problem is only going to grow as high-powered AI-based computers and devices become commonplace. That's why researchers are devising a new type of cooling system that promises to dramatically reduce energy demands.
