Physicists ‘teleport’ logic operation between separated ions

Quantum computing concept (stock image). Credit: © Siarhei / Adobe Stock Physicists at the National Institute of Standards and Technology (NIST) have teleported a computer circuit instruction known as a quantum logic operation between two separated ions (electrically charged atoms), showcasing how quantum computer programs could carry out tasks in future large-scale quantum networks. Quantum…

A rose inspires smart way to collect and purify water

Rose with raindrops. Credit: © Acik / Adobe Stock The rose may be one of the most iconic symbols of the fragility of love in popular culture, but now the flower could hold more than just symbolic value. A new device for collecting and purifying water, developed at The University of Texas at Austin, was…

Comet inspires chemistry for making breathable oxygen on Mars

Oxygen element in periodic table. Credit: © andriano_cz / Adobe Stock Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason -- we humans need molecular oxygen (O2) to breathe, and space is essentially devoid of it. Even on other planets with thick atmospheres, O2 is hard to…

Major step forward in the production of ‘green’ hydrogen

Hydrogen element from periodic table. Credit: © concept w / Adobe Stock The first thermodynamically reversible chemical reactor capable of producing hydrogen as a pure product stream represents a "transformational" step forward in the chemical industry, the authors of a new study claim. The novel reactor, described in the academic journal Nature Chemistry, avoids mixing…

Could gold be the key to making gene therapy for HIV,...

Gold element in periodic table. Credit: © andriano_cz / Adobe Stock Scientists at Fred Hutchinson Cancer Research Center took a step toward making gene therapy more practical by simplifying the way gene-editing instructions are delivered to cells. Using a gold nanoparticle instead of an inactivated virus, they safely delivered gene-editing tools in lab models of…

Table scraps can be used to reduce reliance on fossil fuels

Food waste. Credit: © laboko / Adobe Stock Wasted food can be affordably turned into a clean substitute for fossil fuels. New technology developed by researchers at the University of Waterloo engineers natural fermentation to produce a biodegradable chemical that can be refined as a source of energy. The chemical could also be used to…

Quantum rebar: Quantum dots enhance stability of solar-harvesting perovskite crystals

Solar panels (stock image). Credit: © vegefox.com / Adobe Stock University of Toronto Engineering researchers have combined two emerging technologies for next-generation solar power -- and discovered that each one helps stabilize the other. The resulting hybrid material is a major step toward reducing the cost of solar power while multiplying the ways it can…

Simple test can tell if you’re stressed out

Stress concept. Credit: © boygostockphoto / Adobe Stock Stress is often called "the silent killer" because of its stealthy and mysterious effects on everything from heart disease to mental health. Now researchers at the University of Cincinnati have developed a new test that can easily and simply measure common stress hormones using sweat, blood, urine…

Phase transitions: The math behind the music

Sound word cloud. Credit: © CrazyCloud / Adobe Stock Next time you listen to a favorite tune or wonder at the beauty of a natural sound, you might also end up pondering the math behind the music. You will, anyway, if you spend any time talking with Jesse Berezovsky, an associate professor of physics at…

Geometry of an electron determined for the first time

Quantum computing concept (stock image). Credit: © metamorworks / Adobe Stock Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved…

‘Neural Lander’ uses AI to land drones smoothly

Drone (stock image). Credit: © Denis Rozhnovsky / Adobe Stock Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground as the ground grows ever closer during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous…

Exotic matter uncovered in the sun’s atmosphere

Credit: © Peter Jurik / Adobe Stock Scientists from Ireland and France have announced a major new finding about how matter behaves in the extreme conditions of the Sun's atmosphere. The scientists used large radio telescopes and ultraviolet cameras on a NASA spacecraft to better understand the exotic but poorly understood "fourth…

Origami-inspired materials could soften the blow for reusable spacecraft

Origami shapes (stock image). Credit: © elettaria / Adobe Stock Space vehicles like SpaceX's Falcon 9 are designed to be reusable. But this means that, like Olympic gymnasts hoping for a gold medal, they have to stick their landings. Landing is stressful on a rocket's legs because they must handle the force from the impact…

Unexpected observation of ice at low temperature, high pressure questions water...

Ice crystals (stock image). Credit: © Images By Jefunne / Adobe Stock Through an experiment designed to create a super-cold state of water, scientists at the Department of Energy's Oak Ridge National Laboratory used neutron scattering to discover a pathway to the unexpected formation of dense, crystalline phases of ice thought to exist beyond Earth's…

Scientists break record for highest-temperature superconductor

Lanthanum (periodic table symbol). Credit: © concept w / Adobe Stock University of Chicago scientists are part of an international research team that has discovered superconductivity -- the ability to conduct electricity perfectly -- at the highest temperatures ever recorded. Using advanced technology at UChicago-affiliated Argonne National Laboratory, the team studied a class of materials…

Producing electricity at estuaries using light and osmosis

Example of an estuary, in Maine (stock image). Credit: © mandritoiu / Adobe Stock Most renewable power technologies are weather dependent. Wind farms can only operate when there's a breeze, and solar power plants rely on sunlight. Researchers at EPFL are working on a method to capture an energy source that's constantly available at river…

Original kilogram replaced — new International System of Units (SI) entered...

Calibration weight (stock image). Credit: © djama / Adobe Stock In addition to Ampere, Kelvin, Mol and Co., the kilogram also is now defined by a natural constant. In concrete terms, this means that the original kilogram, which has been the measure of all things for 130 years, has now served its purpose in Paris.…

Big energy savings for tiny machines

Molecular model concept (stock image). Credit: © alice_photo / Adobe Stock Inside all of us are trillions of tiny molecular nanomachines that perform a variety of tasks necessary to keep us alive. In a ground-breaking study, a team led by SFU physics professor David Sivak demonstrated for the first time a strategy for manipulating these…

Artificial photosynthesis transforms carbon dioxide into liquefiable fuels

Carbon dioxide molecules illustration (stock image). Credit: © Ted Reinhard / Adobe Stock Chemists at the University of Illinois have successfully produced fuels using water, carbon dioxide and visible light through artificial photosynthesis. By converting carbon dioxide into more complex molecules like propane, green energy technology is now one step closer to using excess CO2…
