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.

Black holes eat faster than previously expected      (via sciencedaily.com) 

While previous researchers have hypothesized that black holes eat slowly, new simulations indicate that black holes scarf food much faster than conventional understanding suggests. Some quasars brighten and disappear within months -- a time scale that aligns with the new findings.

Tiny sea creatures reveal the ancient origins of neurons      (via sciencedaily.com)     Original source 

A new study sheds new light on the origins of modern brain cells. Researchers find evidence that specialized secretory cells found in placozoans, tiny sea creatures the size of a grain of sand, have many similarities to the neuron, such as the genes required to create a partial synapse. From an evolutionary point of view, early neurons might have started as something like these cells, eventually gaining the ability to create a complete synapse, form axons and dendrites and create ion channels that generate fast electrical signals -- innovations which gave rise to the neuron in more complex animals such as jellyfish. Though the complete story of how the first neuron appeared remains to be told, the study demonstrates that the basic building blocks for our brain cells were forming in the ancestors of placozoans grazing inconspicuously in the shallow seas of Earth around 800 million years ago.

New findings suggest Moon may have less water than previously thought      (via sciencedaily.com) 

A team recently calculated that most of the Moon's permanently shadowed regions (PSRs) are at most around 3.4 billion years old and can contain relatively young deposits of water ice. Water resources are considered key for sustainable exploration of the Moon and beyond, but these findings suggest that current estimates for cold-trapped ices are too high.

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.

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).

Rivers are rapidly warming, losing oxygen; aquatic life at risk      (via sciencedaily.com)     Original source 

Rivers are warming and losing oxygen faster than oceans, according to a new article. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.

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.

Scientists find good places to grow long-spined sea urchins, a starting point to restore 'the lawn mowers of the reefs'      (via sciencedaily.com) 

Scientists are trying to raise as many urchins as possible because they eat algae that could otherwise smother reef ecosystems and kill corals. Researchers have identified algae on which larval sea urchins grow into juveniles in a lab setting.

Some spiders can transfer mercury contamination to land animals      (via sciencedaily.com) 

Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals.

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.

Freshwater connectivity can transport environmental DNA through the landscape      (via sciencedaily.com) 

A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.

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.
