Privacy watchdogs to probe Clearview AI's facial-recognition technology
The federal privacy watchdog and three of his provincial counterparts will jointly investigate Canadian use of facial-recognition technology supplied by U.S. firm Clearview AI.
Department of Energy to Provide $100 Million for Solar Fuels Research
The U.S. Department of Energy (DOE) announced a plan to provide up to $100 million over five years for research on artificial photosynthesis for the production of fuels from sunlight.
Arthi Jayaraman: Then and Now
Arthi Jayaraman is a full professor of Chemical and Biomolecular Engineering and Material Sciences and Engineering in the College of Engineering at the University of Delaware.
Shaping the rings of molecules
Canadian chemists discover a natural process to control the shape of "macrocycles," molecules of large rings of atoms, for use in pharmaceuticals and electronics.
Creating the Heart of a Quantum Computer: Developing Qubits
To use quantum computers on a large scale, we need to improve the technology at their heart - qubits. Qubits are the quantum version of conventional computers' most basic form...
When plasmons reach atomic flatland
Researchers from the MPSD and the Lawrence Berkeley National Laboratory (LBNL) in the United States have discovered a significant new fundamental kind of quantum electronic oscillation, or plasmon, in atomically...
Sneaking up on tiny crystals with electron diffraction
Understanding the structure of proteins, the building blocks of life, is essential to obtain insight into their biological function. Due to their minute size and extreme fragility, these structures are...
Researchers develop high-capacity EV battery materials that double driving range
Dr. Hun-Gi Jung and his research team at the Center for Energy Storage Research of the Korea Institute of Science and Technology (KIST, President Lee Byung Gwon) have announced the...
A step towards controlling spin-dependent petahertz electronics by material defects
The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed...
Shaping the rings of molecules
Macrocycles are molecules made of large rings of atoms. Despite being relatively big and flexible, the molecules don't always stay "floppy"—they can actually lock themselves into specific shapes and geometries.
Scientists crack the mystery of liquid light interactions in organic materials
A team of scientists from the Hybrid Photonics Laboratory at the Skolkovo Institute of Science and Technology (Skoltech) and the University of Sheffield (UK) made a breakthrough in understanding nonlinear...
New method to isolate atomic sheets and create new materials
Researchers have invented a new method -- using ultraflat gold films -- to disassemble vdW single crystals layer by layer into monolayers with near-unity yield and with dimensions limited only...
A little good is good enough -- excuses and 'indulgence effects' in consumption
Ecofriendly materials, produced under good work conditions -- convincing arguments for most of us. But how do consumers really weigh compliance with such ethical standards? Not as much as they...
Scientists predict state of matter that can conduct both electricity and energy perfectly
Three scientists from the University of Chicago have run the numbers, and they believe there may be a way to make a material that could conduct both electricity and energy...
Black phosphorous tunnel field-effect transistor as an ultra-low power switch
Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department of...
Essential oil components can be tested as drug candidates
A research team at the VIB-KU Leuven Center for Microbiology and the KU Leuven Department of Biology showed that, contrary to generally held belief, most components of essential oils could...
Opening the window in your home will not flush out the chemicals in the air
A large team of researchers from across the U.S. and one in Canada has found that simply opening windows will not flush chemicals from the air in most homes. In...
Aerosol optical tweezers advance understanding of airborne particles
Two studies led by faculty in Carnegie Mellon University's Center for Atmospheric Particle Studies show how aerosol optical tweezing can allow scientists to scrutinize the components of the atmosphere with...
Green ammonia could slash farm emissions and power the ships of the future
For the past 100 years, a simple molecule has had an immensely positive impact on our world. Ammonia, which comprises three hydrogen atoms bonded to a single nitrogen atom, is...
Compact dark object search: Scanning Earth's core with superconducting gravimeters
Physics theory suggests that the universe is made up in great part by a type of matter that does not emit, absorb or reflect light, and hence cannot be observed...
A bioplastic that protects against UV radiation
Researchers at the University of Oulu's Research Unit of Sustainable Chemistry have developed a new synthetic bioplastic that, unlike traditional carbon-based plastics or other bioplastics, provides protection from the sun's...
10,000 times faster calculations of many-body quantum dynamics possible
How an electron behaves in an atom, or how it moves in a solid, can be predicted precisely with the equations of quantum mechanics. These theoretical calculations agree fully with...
How the universe could possibly have more dimensions
String theory is a purported theory of everything that physicists hope will one day explain … everything.
For 'blade runners' taller doesn't necessarily mean faster
The governing body for the Paralympics recently lowered the allowable height for sprinters who use prosthetic legs, or blades, during competition. The rules are based on the assumption that the...
Start your morning with a delicious dark roast coffee
Wake up better. (John-Mark Smith via Unsplash/)French roast, Italian roast, and espresso roast are all popular names for coffees, but what does that mean in terms of taste? Dark roast coffee is left...
VR headsets may finally look less ugly
HTC's Proton headset looks like something you might wear snowboarding. (HTC/)It’s hard to look cool while wearing a VR headset. Even as the electronic guts inside have evolved, the bulky devices still typically...
