A spin trio for strong coupling

Posted: 26 Jul 2018 01:11 PM PDT

To make qubits for quantum computers less susceptible to noise, the spin of an electron or some other particle is preferentially used. Researchers have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons.


New family photos of Mars and Saturn from Hubble

Posted: 26 Jul 2018 01:10 PM PDT

In summer 2018 the planets Mars and Saturn are, one after the other, in opposition to Earth. During this event the planets are relatively close to Earth, allowing astronomers to observe them in greater detail. Hubble took advantage of this preferred configuration and imaged both planets to continue its long-standing observation of the outer planets in the solar system.


Enduring ‘radio rebound’ powered by jets from gamma-ray burst

Posted: 26 Jul 2018 01:10 PM PDT

Astronomers using ALMA studied a cataclysmic stellar explosion known as a gamma-ray burst, or GRB, and found its enduring ‘afterglow.’ The rebound, or reverse shock, triggered by the GRB’s powerful jets slamming into surrounding debris, lasted thousands of times longer than expected. These observations provide fresh insights into the physics of GRBs, one of the universe’s most energetic explosions.


New two-dimensional material could revolutionize solar fuel generation

Posted: 26 Jul 2018 01:10 PM PDT

Scientists have obtained from hematite a new material with application as a photocatalyst, christened ‘hematene.’ The three-atom thick hematene is a ferromagnetic material, as opposed to the iron ore from which it was created.


Black holes really just ever-growing balls of string

Posted: 26 Jul 2018 01:10 PM PDT

Black holes aren’t surrounded by a burning ring of fire, after all, suggests new research.




Thin gap on stellar family portrait

Posted: 26 Jul 2018 01:10 PM PDT

A thin gap has been discovered on the Hertzsprung-Russell Diagram (HRD), the most fundamental of all maps in stellar astronomy, a finding that provides new information about the interior structures of low mass stars in the Milky Way Galaxy, according to a new study.


Galaxy outskirts likely hunting grounds for dying massive stars and black holes

Posted: 26 Jul 2018 01:09 PM PDT

Findings from a new study provide further evidence that the outskirts of spiral galaxies host massive black holes. These overlooked regions are new places to observe gravitational waves created when the massive bodies collide, the authors report.


High-precision on-site analysis of precious metals in metallurgical waste spills

Posted: 26 Jul 2018 01:08 PM PDT

Researchers report the application of a portable and efficient method for the on-site analysis of wastewaters for the quantitative analysis of their gold, platinum and palladium content.


A new catalyst for water splitting that is the best of both worlds

Posted: 26 Jul 2018 06:03 AM PDT

Taking water and ripping it apart into hydrogen and oxygen could form the basis of artificial photosynthetic devices that could ultimately power homes and businesses. However, catalysts, including those used to ‘split’ water, have either worked well but are expensive and unstable, or are affordable and stable, but don’t work as well. Now, researchers report a new catalyst that is really the best of both worlds.


Mapping mountaintop coal mining’s yearly spread in Appalachia

Posted: 26 Jul 2018 05:59 AM PDT

A new mapping tool shows, in more detail than ever before, the land laid bare by mountaintop coal mining in central Appalachia each year, going back more than three decades. The tool uses satellite imagery to identify and map the annual extent of mining activity across portions of Kentucky, Tennessee, Virginia and West Virginia. The researchers say the updated maps will make it easier to assess and mitigate mining’s environmental and health impacts.




Soundwave-surfing droplets leave no traces

Posted: 26 Jul 2018 05:58 AM PDT

Engineers have developed a way to manipulate, split and mix droplets of biological fluids by having them surf on acoustic waves in oil. The technology could form the basis of a small-scale, programmable, rewritable biomedical chip that is completely reusable for disparate purposes from on-site diagnostics to laboratory-based research.


New class of materials could be used to make batteries that charge faster

Posted: 26 Jul 2018 05:58 AM PDT

Researchers have identified a group of materials that could be used to make even higher power batteries. The researchers used materials with a complex crystalline structure and found that lithium ions move through them at rates that far exceed those of typical electrode materials, which equates to a much faster-charging battery.


An insect-inspired drone deforms upon impact

Posted: 26 Jul 2018 05:58 AM PDT

An origami-like drone is flexible enough to absorb shocks without breaking before returning to its initial shape. This new type of drone, which was inspired by insect wings, draws on the advantages of both stiff and flexible structures.


Excitons: Taking electronics into the future

Posted: 26 Jul 2018 05:58 AM PDT

Researchers have developed a transistor based on excitons — a type of particle most people have not heard of — that is able to function at room temperature. This breakthrough could lead to a new breed of faster, more energy efficient and smaller electronics.


Chemicals that keep drinking water flowing may also cause fouling

Posted: 26 Jul 2018 05:57 AM PDT

Many city drinking water systems add softening agents to keep plumbing free of pipe-clogging mineral buildup. According to new research, these additives may amplify the risk of pathogen release into drinking water by weakening the grip that bacteria — like those responsible for Legionnaires’ disease — have on pipe interiors.




Artificial enzymes perform reactions on living cells

Posted: 26 Jul 2018 05:57 AM PDT

Nature has evolved thousands of enzymes to facilitate the many chemical reactions that take place inside organisms to sustain life. Now, researchers have designed artificial enzymes that sit on the surfaces of living cells and drive reactions that could someday target drug therapies to specific organs.


Vibrations at an exceptional point

Posted: 26 Jul 2018 05:57 AM PDT

A team of researchers has developed a way to use a light field to trigger a mechanical movement that will generate an acoustic wave.


Team shatters theoretical limit on bio-hydrogen production

Posted: 26 Jul 2018 05:57 AM PDT

An engineered bacterium produced 46 percent more hydrogen per cell than a naturally occurring form of the same species. The research team’s highest reported yield — 5.7 units of hydrogen for every unit of glucose fed to the bacterium — easily surpassed the longstanding theoretical limit of 4 units.


Mars Express detects liquid water hidden under planet’s south pole

Posted: 26 Jul 2018 05:50 AM PDT

Radar data collected by ESA’s Mars Express point to a pond of liquid water buried under layers of ice and dust in the south polar region of Mars.


Scientists unlock the properties of new 2D material

Posted: 24 Jul 2018 04:36 PM PDT

A new two-dimensional material has become a reality, thanks to scientists. The research succeeded in the first experimental realization and structural investigation of single-layer vanadium disulphide (VS2).
