New 'Assembly Theory' unifies physics and biology to explain evolution and complexity      (via sciencedaily.com)     Original source 

An international team of researchers has developed a new theoretical framework that bridges physics and biology to provide a unified approach for understanding how complexity and evolution emerge in nature. This new work on 'Assembly Theory' represents a major advance in our fundamental comprehension of biological evolution and how it is governed by the physical laws of the universe.

Bursts of star formation explain mysterious brightness at cosmic dawn      (via sciencedaily.com)     Original source 

In the James Webb Space Telescope’s (JWST) first images of the universe’s earliest galaxies, the young galaxies appear too bright, too massive and too mature to have formed so soon after the Big Bang. Using new simulations, a team of astrophysicists now has discovered that these galaxies likely are not so massive after all. Although a galaxy’s brightness is typically determined by its mass, the new findings suggest that less massive galaxies can glow just as brightly from irregular, brilliant bursts of star formation.

Colliding neutron stars provide a new way to measure the expansion of the Universe      (via sciencedaily.com)     Original source 

In recent years, astronomy has seen itself in a bit of crisis: Although we know that the Universe expands, and although we know approximately how fast, the two primary ways to measure this expansion do not agree. Now astrophysicists suggest a novel method which may help resolve this tension.

Down goes antimatter! Gravity's effect on matter's elusive twin is revealed      (via sciencedaily.com) 

For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.

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.

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.

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.

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.

Matter comprises of 31% of the total amount of matter and energy in the universe      (via sciencedaily.com) 

One of the most interesting and important questions in cosmology is, 'How much matter exists in the universe?' An international team has now succeeded in measuring the total amount of matter for the second time. The team determined that matter makes up 31% of the total amount of matter and energy in the universe, with the remainder consisting of dark energy.

Dark matter halos measured around ancient quasars      (via sciencedaily.com) 

At the center of every galaxy is a supermassive black hole. Beyond a certain size, these become active, emitting huge amounts of radiation, and are then called quasars. It is thought these are activated by the presence of massive dark matter halos (DMH) surrounding the galaxy, directing matter towards the center, feeding the black hole. A team has now surveyed hundreds of ancient quasars and found this behavior is very consistent throughout history. This is surprising, as many large-scale processes show variation throughout the life of the universe, so the mechanism of quasar activation could have implications for the evolution of the entire universe.
