New recipes for origin of life may point way to distant, inhabited planets      (via sciencedaily.com)     Original source 

Life on a faraway planet -- if it's out there -- might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. Scientists have now exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life. Their ingredient list could focus the search for life elsewhere in the universe by pointing out the most likely conditions -- planetary versions of mixing techniques, oven temperatures and baking times -- for the recipes to come together.

Novel ligands for transition-metal catalysis of photoreactions      (via sciencedaily.com) 

Transition metals exchange electrons with supporting ligands to form complexes that facilitate reaction catalysis in several industries, like pharmaceutical production. Both the metal center and the ligand moiety have pivotal roles in enabling catalysis. While numerous transition metal-catalyzed photoreactions have been developed, only a few new ligands have been reported. Researchers from Chiba University have now developed novel ligands to create transition metal complexes, defining new reaction capabilities.

Laser-based ice-core sampling for studying climate change      (via sciencedaily.com) 

Researchers have developed a new laser-based sampling system for studying the composition of ice cores taken from glaciers. The new system has a 3-mm depth-resolution and is expected to help reconstruct continuous annual temperature changes that occurred thousands to hundreds of thousands of years ago, which will help scientists understand climate change in the past and present.

Snaps supersonic outflow of young star      (via sciencedaily.com) 

Herbig-Haro (HH) objects are luminous regions surrounding newborn stars, formed when stellar winds or jets of gas spewing from these newborn stars form shock waves colliding with nearby gas and dust at high speeds. This image of HH 211 from NASA's James Webb Space Telescope reveals an outflow from a Class 0 protostar, an infantile analog of our Sun when it was no more than a few tens of thousands of years old and with a mass only 8% of the present-day Sun (it will eventually grow into a star like the Sun).

Electrons from Earth may be forming water on the Moon      (via sciencedaily.com) 

Planetary scientists have discovered that high energy electrons in Earth's plasma sheet are contributing to weathering processes on the Moon's surface and, importantly, the electrons may have aided the formation of water on the lunar surface.

New camera offers ultrafast imaging at a fraction of the normal cost      (via sciencedaily.com) 

In a new paper, researchers report a camera that could offer a much less expensive way to achieve ultrafast imaging for a wide range of applications such as real-time monitoring of drug delivery or high-speed lidar systems for autonomous driving. Researchers show that their new diffraction-gated real-time ultrahigh-speed mapping (DRUM) camera can capture a dynamic event in a single exposure at 4.8 million frames per second.

Water world? Methane, carbon dioxide in atmosphere of massive exoplanet      (via sciencedaily.com) 

A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. Webb's discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.

A new way to create germ-killing light      (via sciencedaily.com) 

A research team has created an aluminum-nitride device that can convert visible light into deep-ultraviolet light through the process of second harmonic generation. This work can lead to the development of practical devices that can sterilize surfaces with ultraviolet radiation while using less energy.

Ravenous black hole consumes three Earths'-worth of star every time it passes      (via sciencedaily.com) 

Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.

How pulsating pumping can lead to energy savings      (via sciencedaily.com) 

Pumping liquids may seem like a solved problem but optimizing the process is still an area of active research. Any pumping application -- from industrial scales to heating systems at home -- would benefit from a reduction in energy demands. Researchers now showed how pulsed pumping can reduce both friction from and energy consumption of pumping. For this, they took inspiration from a pumping system intimately familiar to everyone: the human heart.

Webb reveals new structures within iconic supernova      (via sciencedaily.com) 

NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.
