In these computers, trapped ions serve as quantum bits that are entangled in order to perform advanced computations.

Inducing plasma in biomass could make biogas easier to produce

Producing biogas from the bacterial breakdown of biomass presents options for a greener energy future, but the complex composition of biomass comes with a long list of challenges.

Evaporation critical to coronavirus transmission as weather changes

As COVID-19 cases continue to rise worldwide, it is increasingly urgent to understand how climate impacts the continued spread of the coronavirus, particularly as winter virus infections are more common and countries in the northern hemisphere will soon see cooler temperatures.

The results have recently been published in the renowned online journal Nature Communications.

Parylene photonics enable future optical biointerfaces

Carnegie Mellon University's Maysam Chamanzar and his team have invented an optical platform that will likely become the new standard in optical biointerfaces. He's labeled this new field of optical technology "Parylene photonics," demonstrated in a recent paper in Nature Microsystems and Nanoengineering.

Squeezed light makes Virgo's mirrors jitter

Quantum mechanics does not only describe how the world works on its smallest scales, but also affects the motion of macroscopic objects. An international research team, including four scientists from the MPI for Gravitational Physics (Albert-Einstein-Institut/AEI) and Leibniz University in Hannover, Germany, has shown how they can influence the motion of mirrors, each weighing more than 40 kg, in the Advanced Virgo gravitational-wave detector trough the deliberate use of quantum mechanics. At the core of their experiment published today in Physcial Review Letters is a squeezed-light source, developed and built at the AEI in Hanover, which generates specially tuned laser radiation and improves the detector's measurement sensitivity during observing runs.

Between relativistic and classical wave regimes, newly discovered memory effect alters the Doppler wave signature

Wave scattering appears practically everywhere in everyday life—from conversations across rooms, to ocean waves breaking on a shore, from colorful sunsets, to radar waves reflecting from aircraft. Scattering phenomena also appear in realms as diverse as quantum mechanics and gravitation. According to Pavel Ginzburg, professor at Tel Aviv University's School of Electrical Engineering, these phenomena become especially interesting when the waves in question encounter a moving object.

Astronomy and Space news

Can ripples on the sun help predict solar flares?

Solar flares are violent explosions on the sun that fling out high-energy charged particles, sometimes toward Earth, where they disrupt communications and endanger satellites and astronauts.

NASA plans for return to Moon to cost $28 billion

NASA on Monday revealed its latest plan to return astronauts to the Moon in 2024, and estimated the cost of meeting that deadline at $28 billion, $16 billion of which would be spent on the lunar landing module.

NASA technology enables precision landing without a pilot

Some of the most interesting places to study in our solar system are found in the most inhospitable environments—but landing on any planetary body is already a risky proposition. With NASA planning robotic and crewed missions to new locations on the Moon and Mars, avoiding landing on the steep slope of a crater or in a boulder field is critical to helping ensure a safe touch down for surface exploration of other worlds. In order to improve landing safety, NASA is developing and testing a suite of precise landing and hazard-avoidance technologies.

Insight-HXMT discovers closest high-speed jet to black hole

Insight-HXMT, China's first space X-ray astronomical satellite, has discovered a low-frequency quasi-periodic oscillation (QPO) above 200 kiloelectron volts (keV) in a black hole binary, making it the highest energy low-frequency QPO ever found. The scientists also found that the QPO originated from the precession of a relativistic jet (high-speed outward-moving plasma stream) near the event horizon of the black hole. These discoveries have important implications for resolving the long-running debate about the physical origin of low-frequency QPOs.

NASA's OSIRIS-REx to asteroid Bennu: 'You've got a little Vesta on you'

In an interplanetary faux pas, it appears some pieces of asteroid Vesta ended up on asteroid Bennu, according to observations from NASA's OSIRIS-REx spacecraft. The new result sheds light on the intricate orbital dance of asteroids and on the violent origin of Bennu, which is a "rubble pile" asteroid that coalesced from the fragments of a massive collision.

Water on exoplanet cloud tops could be found with hi-tech instrumentation

University of Warwick astronomers have shown that water vapor can potentially be detected in the atmospheres of exoplanets by peering literally over the tops of their impenetrable clouds.

Astrophysicists prove that dust particles in space are mixed with ice

The matter between the stars in a galaxy—called the interstellar medium—consists not only of gas, but also of a great deal of dust. At some point in time, stars and planets originated in such an environment, because the dust particles can clump together and merge into celestial bodies. Important chemical processes also take place on these particles, from which complex organic—possibly even prebiotic—molecules emerge.

Starspots: Revving up the variability of solar-like stars

In cosmic comparison, the Sun is a bore. While the brightness of some other stars with similar characteristics fluctuates strongly, the Sun's variations are much more moderate. Scientists from the Max Planck Institute for Solar System Research (MPS) in Germany, from the Turkish-German University and Boğaziçi University in Turkey, and from Kyung Hee University in South Korea, have now investigated how exactly sun- and starspots affect this behavior. In addition to the number and size of the spots, their distribution plays a crucial role. If groups of sunspots were to appear more frequently clumped together in so-called nests, the Sun's brightness variations could well keep up with those of its cosmic peers. The team reports on its results in today's issue of the Astrophysical Journal Letters.

Data sonification: Sounds from around the Milky Way

The center of our Milky Way galaxy is too distant for us to visit in person, but we can still explore it. Telescopes give us a chance to see what the Galactic Center looks like in different types of light. By translating the inherently digital data (in the form of ones and zeroes) captured by telescopes in space into images, astronomers create visual representations that would otherwise be invisible to us.

NASA's new Mars rover will use X-rays to hunt fossils

NASA's Mars 2020 Perseverance rover has a challenging road ahead: After having to make it through the harrowing entry, descent, and landing phase of the mission on Feb. 18, 2021, it will begin searching for traces of microscopic life from billions of years back. That's why it's packing PIXL, a precision X-ray device powered by artificial intelligence (AI).

The method, which has been tested by running simulations on a climate-control system for a 100-room building, is poised to deliver energy savings of around 20%.

When bots do the negotiating, humans more likely to engage in deceptive techniques

Recently computer scientists at USC Institute of Technologies (ICT) set out to assess under what conditions humans would employ deceptive negotiating tactics. Through a series of studies, they found that whether humans would embrace a range of deceptive and sneaky techniques was dependent both on the humans' prior negotiating experience in negotiating as well as whether virtual agents where employed to negotiate on their behalf. The findings stand in contrast to prior studies and show that when humans use intermediaries in the form of virtual agents, they feel more comfortable employing more deceptive techniques than they would normally use when negotiating for themselves.
