Nonlinear polyatomic molecule, CaOCH3 laser-cooled to ~700 mK

A team of researchers at Harvard University has developed a way to cool nonlinear polyatomic molecules to extremely cold temperatures. In their paper published in the journal Science, the group describes their method and possible uses for it. Eric Hudson with the University of California, Los Angeles, has published a Perspective piece in the same issue describing the decades-long history of work involved in attempting to cool complex molecules, and also outlines the work by the team in California.

A phonon laser: Coherent vibrations from a self-breathing resonator

Lasing—the emission of a collimated light beam of light with a well-defined wavelength (color) and phase—results from a self-organization process, in which a collection of emission centers synchronizes itself to produce identical light particles (photons). A similar self-organized synchronization phenomenon can also lead to the generation of coherent vibrations—a phonon laser, where phonon denotes, in analogy to photons, the quantum particles of sound.

Computational modelling explains why blues and greens are brightest colous in nature

Researchers have shown why intense, pure red colors in nature are mainly produced by pigments, instead of the structural color that produces bright blue and green hues.

Astronomy and Space news

Carbon-rich exoplanets may be made of diamonds

As missions like NASA's Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists are increasingly able to piece together what these planets look like, what they are made of, and if they could be habitable or even inhabited.

Galactic census reveals origin of most 'extreme' galaxies

Astronomers have found that the key to understanding galaxies with "extreme" sizes, either small or large, may lie in their surroundings. In two related studies, an international team found that galaxies that are either "ultra-compact" or "ultra-diffuse" relative to normal galaxies of comparable brightness appear to reside in dense environments, i.e., regions that contain large numbers of galaxies. This has led the team to speculate that these "extreme" objects could have started out resembling normal galaxies, but then evolved to have unusual sizes through interactions with other galaxies.

The evolving chemistry of protoplanetary disks

Planets form from the gas and dust in disks that surround young stars. Chemicals in the disk that evaporate easily, called volatiles, include important molecules like water, carbon monoxide, nitrogen, as well as other simple organic molecules. The amount of volatile material that accumulates in a planet as it forms is a key factor in determining the planet's atmosphere and suitability for life, and depends on the details of the gas and ice reservoirs in the disk at the time of planet formation.

Martian Moons eXploration spacecraft to take ultra-high definition images of Mars via 8K camera

The Japan Aerospace Exploration Agency (JAXA) and Japan Broadcasting Corporation (NHK) have decided to jointly develop the Super Hi-Vision Camera that is capable of filming 4K and 8K images in space for JAXA's Martian Moons eXploration (MMX) mission. This would be the first time in history that 8K ultra-high-definition images of Mars and its moons are taken in proximity. By combining the actual flight data of the MMX spacecraft and the images taken by the Super Hi-Vision Camera, the exploration of the MMX spacecraft around Mars and its moons (the Martian system), 300 million kilometers from the Earth, will be recreated.

China is building a floating spaceport for rocket launches

In the near future, launch facilities located at sea are expected to be a lot more common. SpaceX announced that it is hoping to create offshore facilities in the near future for the sake of launching the Starship away from populated areas. And China, the latest member of the superpowers-in-space club, is currently building the "Eastern Aerospace Port" off the coast of Haiyang city in the eastern province of Shandong.

Are your devices spying on you? Australia's very small step to make the Internet of Things safer

From internet-connected televisions, toys, fridges, ovens, security cameras, door locks, fitness trackers and lights, the so-called "Internet of Things" (IoT) promises to revolutionize our homes.

AI tech to spot dangerous drivers

New license recognition technology could one day be used to detect dangerous drivers before problems arise.

Computer scientists use artificial intelligence to predict the frequencies of drug side effects

A new algorithm has been developed by academics at Royal Holloway, University of London, to predict the side effects of drugs before they hit the market by using the same principle by which movies are recommended to users.

Development of a multivalued optical memory composed of two-dimensional materials

The National Institute for Materials Science (NIMS) has developed a memory device capable of storing multiple values using both optical and voltage input values. This device composed of layered two-dimensional materials is able to optically control the amount of charge stored in these layers. This technology may be used to significantly increase the capacity of memory devices and applied to the development of various optoelectronic devices.

Study reviews impact of wind energy on local Indiana communities

Wind power electricity generation arrived on the Indiana landscape in 2008. Early projects were concentrated in areas with favorable wind conditions. But a recent study by Purdue researchers revealed that subsequent innovations in wind power technologies, such as taller turbines with larger capacities, have made it economically viable for other Indiana areas to host utility-scale wind farms.

Airlines, unions running out of time to get more federal aid

A couple hundred flight attendants and pilots rallied this week on Capitol Hill and tweeted at lawmakers, asking them for $25 billion in additional federal funds to prevent airline furloughs next month.
