Published How organic solar cells could become significantly more efficient
(via sciencedaily.com)
Original source 
The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material. Now a research group has shown that certain organic dyes can help build virtual highways for the energy.
Published Hidden supermassive black holes reveal their secrets through radio signals
(via sciencedaily.com) 
Astronomers have found a striking link between the amount of dust surrounding a supermassive black hole and the strength of the radio emission produced in extremely bright galaxies.
Published Efficient fuel-molecule sieving using graphene
(via sciencedaily.com) 
A research team has successfully developed a new method that can prevent the crossover of large fuel molecules and suppress the degradation of electrodes in advanced fuel cell technology using methanol or formic acid. The successful sieving of the fuel molecules is achieved via selective proton transfers due to steric hindrance on holey graphene sheets that have chemical functionalization and act as proton-exchange membranes.
Published Astronomers discover newborn galaxies with the James Webb Space Telescope
(via sciencedaily.com) 
With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the Universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed. But for the first time we now see signs that this relation between the amount of stars and elements does not hold for the earliest galaxies. The reason is likely that these galaxies simply are in the process of being created, and have not yet had the time to create the heavy elements.
Published Astronomers find abundance of Milky Way-like Galaxies in early Universe, rewriting cosmic evolution theories
(via sciencedaily.com) 
Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to new research.
Published Shh! Quiet cables set to help reveal rare physics events
(via sciencedaily.com) 
Newly developed ultra-low radiation cables reduce background noise for neutrino and dark matter detectors.
Published Predicting the sustainability of a future hydrogen economy
(via sciencedaily.com) 
As renewable energy sources like wind and solar ramp up, they can be used to sustainably generate hydrogen fuel. But implementing such a strategy on a large scale requires land and water dedicated to this purpose.
Published Sustainable energy for aviation: What are our options?
(via sciencedaily.com) 
Scientists and industry leaders worldwide are looking for answers on how to make aviation sustainable by 2050 and choosing a viable sustainable fuel is a major sticking point. Aerospace engineers took a full inventory of the options to make a data-driven assessment about how they stack up in comparison. He reviewed over 300 research projects from across different sectors, not just aerospace, to synthesize the ideas and draw conclusions to help direct the dialogue about sustainable aviation toward a permanent solution.
Published Tag team of the James Webb Space Telescope and ALMA captures the core of the most distant galaxy protocluster
(via sciencedaily.com) 
An international research team has used the James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array to observe the most distant galaxy protocluster to date, 13.14 billion light-years away. The team has successfully captured the 'core region' of the galaxy protocluster, which corresponds to a metropolitan area with a particularly high number density of galaxies. The team has revealed that many galaxies are concentrated in a small area and that the growth of galaxies is accelerated. Furthermore, the team used simulations to predict the future of the metropolitan area and found that the region will merge into one larger galaxy within tens of millions of years. These results are expected to provide important clues regarding the birth and growth of galaxies.
Published Efficient next-generation solar panels on horizon following breakthrough
(via sciencedaily.com) 
A scientific breakthrough brings mass production of the next generation of cheaper and lighter perovskite solar cells one step closer.
Published Chameleon-inspired coating could cool and warm buildings through the seasons
(via sciencedaily.com) 
As summer turns to fall, many people will be turning off the air conditioning and firing up heaters instead. But traditional heating and cooling systems are energy intensive, and because they typically run on fossil fuels, they aren't sustainable. Now, by mimicking a desert-dwelling chameleon, a team has developed an energy-efficient, cost-effective coating. The material could keep buildings cool in the summers -- or warm in the winters -- without additional energy.
Published New Si-based photocatalyst enables efficient solar-driven hydrogen production and biomass refinery
(via sciencedaily.com) 
A research team has achieved a significant breakthrough in the development of a hybrid silicon photocatalyst.
Published Tall buildings could be built quicker if damping models were correct, study finds
(via sciencedaily.com) 
Multi-story buildings are assembled over-cautiously to withstand wind strengths, researchers have found.
Published 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.
Published Cheap and efficient catalyst could boost renewable energy storage
(via sciencedaily.com) 
Storing renewable energy as hydrogen could soon become much easier thanks to a new catalyst based on single atoms of platinum.
Published How wind turbines react to turbulence
(via sciencedaily.com) 
The output of wind turbines can rise or fall by 50 per cent in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.
Published Predictive model could improve hydrogen station availability
(via sciencedaily.com) 
Consumer confidence in driving hydrogen-fueled vehicles could be improved by having station operators adopt a predictive model that helps them anticipate maintenance needs, according to researchers.
Published Step change in upconversion the key to clean water, green energy and futuristic medicine

Achieving photochemical upconversion in a solid state is a step closer to reality, thanks to a new technique that could unlock vital innovations in renewable energy, water purification and advanced healthcare.
Published Brilliant galaxies of early universe
(via sciencedaily.com) 
Scientists have used data from the James Webb Space Telescope (JWST) as part of the Cosmic Evolution Early Release Science (CEERS) Survey to change the way we think about the universe and its distant galaxies. Astronomers authored a paper confirming very bright galaxies in the early universe, while also disproving the identification of what would have been the most distant galaxy ever found.
