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......»»
Nematic transition and nanoscale suppression of superconductivity in an iron chalcogenide
In unconventional superconductors, electrons often exhibit a tendency towards spatial ordering within their atomic structure......»»

Researchers from Tohoku University have developed a new numerical method that paves the way for simulating landslide tsunamis......»»
Simulating sneezes and coughs to show how COVID-19 spreads
Researchers have published papers on the droplets of liquid sprayed by coughs or sneezes and how far they can travel under different conditions. Their findings reinforce the importance of wearing masks, maintaining social distancing, avoiding poorly.....»»
Low-temperature physics gives insight into turbulence
A novel technique for studying vortices in quantum fluids has been developed by Lancaster physicists......»»
Simulating sneezes and coughs to show how COVID-19 spreads
Two groups of researchers at Sandia National Laboratories have published papers on the droplets of liquid sprayed by coughs or sneezes and how far they can travel under different conditions......»»
Six typefaces that make use of the human body and bodily fluids
Here are six examples of typography informed by or made using the human body, including a sex-position typeface, wispy letters formed from strands of hair and letters traced from urine. Read more Here are six examples of typography informed.....»»
Deep under the ocean, microbes are active and poised to eat whatever comes their way
The subseafloor constitutes one of the largest and most understudied ecosystems on Earth. While it is known that life survives deep down in the fluids, rocks, and sediments that make up the seafloor, scientists know very little about the conditions a.....»»
NASA to participate in tabletop exercise simulating asteroid impact
JPL's Center for Near Earth Object Studies will lead the hypothetical impact scenario to see how international agencies respond to an actual impact prediction......»»
Reversal of blood droplet flight predicted, captured in experiments
Forensic science includes the analysis of blood backspatter involved in gunshot wounds, but scientific questions about the detailed role of fluids in these situations remained unresolved......»»
Research team discovers use of elasticity to position microplates on curved 2D fluids
A team of polymer science and engineering researchers at the University of Massachusetts Amherst has demonstrated for the first time that the positions of tiny, flat, solid objects integrated in nanometrically thin membranes—resembling those of bio.....»»
Underground noise reveals fracture pathways needed for energy production
Both oil production and geothermal energy need fluids to move through fracture channels within subsurface rocks. Yet accurately mapping and measuring fractures created for fluid flow is challenging, because what happens underground goes unseen......»»
A general-purpose force field for coarse-grained molecular dynamics
Simulating the interactions between atoms and molecules is important for many scientific studies. However, accurate simulations can take a long time, which limits their use. To speed up simulations without sacrificing too much detail, Siewert-Jan Mar.....»»
The collective movement of nanorobots observed in vivo
Nanobots are machines whose components are at the nano-scale (one-millionth of a millimeter), and can be designed in such a way that they have the ability to move autonomously in fluids. Although they are still in the research and development phase,.....»»
"We marry disorder with order": The effects of geometrical disorder on fluids and solids in mesoporous materials
We've all come across them before: those little bags of small balls that come packed together with new shoes or electrical goods. The balls are there to absorb moisture so as to protect the items from damage. "These materials act like a sponge," expl.....»»
Pioneering study gives new insight into formation of copper deposits
A groundbreaking study has given new insights into how copper deposit-forming fluids are transported naturally from their source deep underground towards the Earth's surface......»»
New mechanism found for generating giant vortices in quantum fluids of light
Anyone who has drained a bathtub or stirred cream into coffee has seen a vortex, a ubiquitous formation that appears when fluid circulates. But unlike water, fluids governed by the strange rules of quantum mechanics have a special restriction: as was.....»»
Small volcanic lakes tapping giant underground reservoirs
In its large caldera, Newberry volcano (Oregon, U.S.) has two small volcanic lakes, one fed by volcanic geothermal fluids (Paulina Lake) and one by gases (East Lake). These popular fishing grounds are small windows into a large underlying reservoir o.....»»
