Why boiling droplets can race across hot oily surfaces

When you're frying something in a skillet and some droplets of water fall into the pan, you may have noticed those droplets skittering around on top of the film of hot oil. Now, that seemingly trivial phenomenon has been analyzed and understood for the first time by researchers at MIT—and may have important implications for microfluidic devices, heat transfer systems, and other useful functions.

Neutrons help measure cell membrane viscosity—and reveal its basis

We now have a clearer picture of the lightning-fast molecular dance occurring within the membrane that encloses each cell in our body, revealed in part by neutron beams at the National Institute of Standards and Technology (NIST). The findings may have applications in drug development, and they also address long-standing fundamental mysteries about why cell membranes move as they do.

Shielding ultracold molecules with microwaves

Ultracold molecules are promising for applications in new quantum technologies. Unfortunately, these molecules are destroyed upon colliding with each other. Researchers at Harvard University, MIT, Korea University and Radboud University have demonstrated that these collisional losses can be prevented by guiding the interaction between molecules using microwaves in such a way that they repel each other and, therefore, do not come close to each other during collisions. Their paper will be published in Science on 13 August.

Engineers make critical advance in quantum computer design

Quantum engineers from UNSW Sydney have removed a major obstacle that has stood in the way of quantum computers becoming a reality. They discovered a new technique they say will be capable of controlling millions of spin qubits—the basic units of information in a silicon quantum processor.

Progress in algorithms makes small, noisy quantum computers viable

As reported in a new article in Nature Reviews Physics, instead of waiting for fully mature quantum computers to emerge, Los Alamos National Laboratory and other leading institutions have developed hybrid classical/quantum algorithms to extract the most performance—and potentially quantum advantage—from today's noisy, error-prone hardware. Known as variational quantum algorithms, they use the quantum boxes to manipulate quantum systems while shifting much of the work load to classical computers to let them do what they currently do best: solve optimization problems.

A complete platform for quantum computing

In a new groundbreaking work, researchers from DTU have now realized the complete platform for an optical quantum computer. The platform is universal and scalable, it all takes place at room temperature, and the technology is directly compatible with standard fiber optic networks. This puts DTU right at the forefront of the development.

Researchers develop new way to study neurodegenerative diseases

Some proteins in cells can separate into small droplets like oil droplets in water, but faults in this process may underlie neurodegenerative diseases in the brains of older people. Now, Rutgers researchers have developed a new method to quantify protein droplets involved in these diseases.

Electrically-tunable metasurfaces using dual epsilon-near-zero resonances

Image: Hubble peers into a dusty stellar nursery

Nestled among the vast clouds of star-forming regions like this one lie potential clues about the formation of our own solar system.

Growing crops on Mars? Probably not under the naked sun

If humans want to live on Mars for a longer period it will be necessary to grow their own crops over there. And what is more logical than growing the crops in a greenhouse on the surface, profiting from the sunlight, as seen in many scientific designs and Sci-fi movies? However, will this be possible giving the high amount of cosmic radiation at the Martian surface level? Wageningen University & Research and the Reactor Institute Delft (RID, TU Delft) have been investigating for some time now the effect of cosmic radiation on Martian surface on plant growth. This revealed that, just like humans, plants also need to be protected from the cosmic radiation.

Heat transfer experiment arrives at International Space Station

People who design spacecraft must prioritize two factors: reducing weight and managing extreme temperatures.

Faster path planning for rubble-roving robots

A new algorithm speeds up path planning for robots that use arm-like appendages to maintain balance on treacherous terrain such as disaster areas or construction sites, researchers at the University of Michigan have shown. The improved path planning algorithm found successful paths three times as often as standard algorithms, while needing much less processing time.

A holistic approach to materials for the next generation of electrical insulation

Our electrical infrastructure has remained largely unchanged since World War II, but advances in technology—specifically materials—opened doors we never would have thought possible in the past. These advances have set the stage to redesign our electrical infrastructure for the next 100 years and beyond.

How hackers can 'poison' open-source code

Cornell Tech researchers have discovered a new type of online attack that can manipulate natural-language modeling systems and evade any known defense—with possible consequences ranging from modifying movie reviews to manipulating investment banks' machine-learning models to ignore negative news coverage that would affect a specific company's stock.

NREL's thermoplastic blade research dives deep with verdant power's tidal energy turbines

National Renewable Energy Laboratory (NREL) researchers have been exploring the use of thermoplastic composite materials for wind turbines for several years, but they have only just begun to scrape the surface of how these materials perform underwater. For the first time in history, thermoplastic composite blades, which have the potential to revolutionize the marine energy industry, are being tested on a large-scale tidal power turbine.

New study on costs and benefits of new transportation technologies the most comprehensive to date

A new Argonne study offers the most complete understanding yet of the costs of owning and operating a vehicle and how those costs vary by powertrain, from the conventional to the cutting-edge.

Smart energy meter shows energy generation instead of consumption

An energy meter indicates that hundreds of watts are generated but in reality a small amount of power is consumed. This can happen using the combination of a dimmer and some household equipment, which together only consume about twenty watts. Depending on the actual setting of the dimmer, the energy meter gives the correct read-out, a consumption that is twenty times higher, or even hundreds of watts of generated power. Researchers from the University of Twente will present and explain this effect on the large online conference on electromagnetic compatibility, EMC 2021.
