DNA-like material could bring even smaller transistors
Computer chips use billions of tiny switches, called transistors, to process information. The more transistors on a chip, the faster the computer. A material shaped like a one-dimensional DNA helix...
MLB players react to possible change in playoff format
Major League Baseball is considering several substantial rule changes to its playoff format. Several players said they are opposed to the potential postseason transformation.
Artificial atoms create stable qubits for quantum computing
Quantum engineers from UNSW Sydney have created artificial atoms in silicon chips that offer improved stability for quantum computing.
Using sound and light to generate ultra-fast data transfer
Researchers have made a breakthrough in the control of terahertz quantum cascade lasers, which could lead to the transmission of data at the rate of 100 gigabits per second—around one...
Atom or noise? New method helps cryo-EM researchers tell the difference
Cryogenic electron microscopy, or cryo-EM, has reached the point where researchers could in principle image individual atoms in a 3-D reconstruction of a molecule—but just because they could see those...
New method offers more stable, efficient electrocatalytic reactions
Northwestern University researchers have developed a more efficient and stable method to conduct electrocatalytic reactions.
New threads: Nanowires made of tellurium and nanotubes hold promise for wearable tech
Wearable tech and electronic cloth may be the way of the future, but to get there the wiring needs to be strong, flexible and efficient.
New Threads: Nanowires Made of Tellurium and Nanotubes Hold Promise for Wearable Tech
Wearable tech requires both strength and flexibility. A new nanowire design -- a boron nitride nanotube (BNNT) filled with tellurium atomic chains -- holds promise for electronics triggered by light...
First CMV-22B Osprey plane delivered to U.S. Navy
The U.S. Navy announced the delivery of its first tiltrotor CMV-22B Osprey-variant aircraft on Monday.
Straightforward path to linear alkylbenzenes identified
Nickel catalyst provides a route to the cleaning product chemicals with high yields and selectivity
Chemists develop safer hydrogenation processes
Safe and environmentally-friendly hydrogen gas on demand could be on the horizon following a new "hydrogenation" chemical process in development at The City College of New York. Led by Mahesh...
Chemistry technique is 'warp drive' for creating better synthetic molecules for medicine
In a study with implications for the future of drug discovery, Scripps Research scientists showed they were able to turn simple chemicals into unique 3-D structures resembling those found in...
The science behind a firework’s big ka-boom
Bang bang (Alessandro Rustighi/)Even the most elaborate fireworks show starts with a single crack, as black powder shoots shell from mortar. That launch sets off a cascade of whooshes, zips, and bangs that...
But what about flow? The effect of hydrodynamics on liquid-liquid transitions
For a long time, the liquid state of pure substances was believed to be a continuous state in which the component atoms or molecules are all equivalent. However, it has...
DNA-like material could bring even smaller transistors
A material shaped like a one-dimensional DNA helix might further push the limits on a transistor's size. The material comes from a rare earth element called tellurium.
Chemists develop safer hydrogenation processes
Safe and environmentally-friendly hydrogen gas on demand could be on the horizon following a new 'hydrogenation' chemical process. The research uniquely bypasses the need for an external source of hydrogen...
Argonne engineers streamline jet engine design
Argonne scientists are combining one-of-a-kind x-ray experiments with novel computer simulations to help engineers at aerospace and defense companies save time and money.
Look: Sophia Lillis appears in bloody 'I Am Not Okay with This' poster
Sophia Lillis and Wyatt Olef star in a Netflix adaptation of the Charles Forsman graphic novel "I Am Not Okay with This."
Is it hemp or marijuana? New scanner gives instant answer
Hemp is technically legal in Texas, but proving that hemp is not marijuana can be a hurdle, requiring testing in a licensed laboratory. Now, a team of researchers have created...
Dissecting a lightning strike, from flash to boom
It shot me down (Alessandro Rustighi/)Most lightning just bounces around within its cloud of origin. But the rogue charges that escape are enough to dazzle observers, inspire awe and fear (which is fair—the...
Honeywell nets $3.5B deal for new Air Force navigation system sustainment
Honeywell Inc. was awarded a contract worth up to $3.5 billion for development and sustainment of the Air Force's new Embedded GPS Inertial Navigation System Modernization, including the 1st system...
When Electrons Follow New Interaction Rules, Superconductivity Ensues
Researchers used a scanning tunneling microscope to "see" the electron interactions and pairings at the heart of twisted bilayer graphene's novel properties.
Creating the Heart of a Quantum Computer
Quantum computers have the potential to solve problems that conventional computers can't. To use quantum computers on a large scale, we need to improve the technology in qubits. The DOE's...
Not everything is ferromagnetic in high magnetic fields
High magnetic fields have a potential to modify the microscopic arrangement of magnetic moments because they overcome interactions existing in a zero field. Usually, high fields exceeding a certain critical...
'Reverse fuel cell' converts waste carbon to valuable products at record rates
Fuel cells turn chemicals into electricity. Now, a University of Toronto Engineering team has adapted technology from fuel cells to do the reverse: harness electricity to make valuable chemicals from...
A thermometer that can be stretched and deformed by water
Recent outbreaks of the novel coronavirus have emphasized the importance of quarantine and prevention more than ever. When monitoring changes in our body, body temperature is measured first, so it...
