Optically trapped quantum droplets of light can bind together to form macroscopic complexes

Condensed matter systems and photonic technologies are regularly used by researchers to create microscale platforms that can simulate the complex dynamics of many interacting quantum particles in a more accessible setting. ...

Engineers build chemically driven wheels that 'morph' into gears to perform mechanical work

The gear is one of the oldest mechanical tools in human history and led to machines ranging from early irrigation systems and clocks, to modern engines and robotics. For the first time, researchers at the University of Pittsburgh ...

What tiny surfing robots teach us about surface tension

Propelled by chemical changes in surface tension, microrobots surfing across fluid interfaces lead researchers to new ideas.

Ironing out the difficulties of moving fluids in space

Fluid flows downhill—at least it does on Earth. Fluid movement becomes much more complicated in space, and that creates challenges for systems that rely on pumping fluids around for thermal control, engine propellants and ...

How cytoplasm 'feels' to a cell's components

Under a microscope, a cell's cytoplasm can resemble a tiny underwater version of New York's Times Square: Thousands of proteins swarm through a cytoplasm's watery environment, coming together and breaking apart like a cytoskeletal ...

Understanding oceanic earthquake precursors

Published on 14 September in Nature Geoscience, a study conducted by researchers from several institutes, including IFREMER (French Research Institute for Exploitation of the Sea), CNRS and IFSTTAR, offers the first theoretical ...

Physics of complex fluids: Ring polymers show unexpected motion patterns under shear

The shearing of fluids—meaning the sliding of fluid layers over each other under shear forces—is an important concept in nature and in rheology, the science that studies the flow behavior of matter, including liquids ...

Investigating the intestinal transport of mercury ions with a gut-on-a-chip device

The transport of mercury ions across intestinal epithelial cells can be studied for toxicology assessments by using animal models and static cell cultures. However, the concepts do not reliably replicate conditions of the ...

Swapping water for CO2 could make fracking greener and more effective

Scientists at the Chinese Academy of Sciences and China University of Petroleum (Beijing) have demonstrated that CO2 may make a better hydraulic fracturing (fracking) fluid than water. Their research, published May 30 in ...

How slippery surfaces allow sticky pastes and gels to slide

An MIT research team that has already conquered the problem of getting ketchup out of its bottle has now tackled a new category of consumer and manufacturing woe: how to get much thicker materials to slide without sticking ...
