Astronomers discover heavy elements after bright gamma-ray burst from neutron star merger      (via sciencedaily.com)     Original source 

An international team of astronomers obtained observational evidence for the creation of rare heavy elements in the aftermath of a cataclysmic explosion triggered by the merger of two neutron stars.

'Cosmic lighthouses' that cleared primordial fog identified with JWST      (via sciencedaily.com)     Original source 

Scientists working with data from NASA's James Webb Space Telescope (JWST) have obtained the first full spectra of some of the earliest starlight in the universe. The images provide the clearest picture yet of very low-mass, newborn galaxies, created less than a billion years after the Big Bang, and suggest the tiny galaxies are central to the cosmic origin story.

Webb finds evidence for neutron star at heart of young supernova remnant      (via sciencedaily.com)     Original source 

NASA's James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a core-collapse supernova, meaning the compacted remains at its core formed either a neutron star or a black hole. Evidence for such a compact object has long been sought, and while indirect evidence for the presence of a neutron star has previously been found, this is the first time that the effects of high-energy emission from the probable young neutron star have been detected.

A new beginning: The search for more temperate Tatooines      (via sciencedaily.com)     Original source 

Luke Skywalker's childhood might have been slightly less harsh if he'd grown up on a more temperate Tatooine -- like the ones identified in a new study. According to the study's authors, there are more climate-friendly planets in binary star systems -- in other words, those with two suns -- than previously known. And, they say, it may be a sign that, at least in some ways, the universe leans in the direction of orderly alignment rather than chaotic misalignment.

Stronger storms free more nutrients from mud flats      (via sciencedaily.com)     Original source 

If storms become stronger in the future due to climate change, more nitrogen may be released from the bottom of coastal seas.

Brightest and fastest-growing: Astronomers identify record-breaking quasar      (via sciencedaily.com)     Original source 

Astronomers have characterized a bright quasar, finding it to be not only the brightest of its kind, but also the most luminous object ever observed. Quasars are the bright cores of distant galaxies and they are powered by supermassive black holes. The black hole in this record-breaking quasar is growing in mass by the equivalent of one Sun per day, making it the fastest-growing black hole to date.

Converting rainforest to plantation impacts food webs and biodiversity      (via sciencedaily.com)     Original source 

Every day, new areas of rainforests are converted into plantations, drastically changing tropical biodiversity and the way the ecosystem functions. Yet, the current understanding of the consequences is fragmentary: previous studies tended to examine either biodiversity or the ecosystem. An international research team brings these threads together in this study. They analyzed organisms ranging from microscopic mites and earthworms in the soil, to beetles and birds in tree canopies, comparing tropical rainforest with rubber and oil palm plantations in Sumatra, Indonesia.

Black hole at center of the Milky Way resembles a football      (via sciencedaily.com)     Original source 

The supermassive black hole in the center of the Milky Way is spinning so quickly it is warping the spacetime surrounding it into a shape that can look like a football, according to a new study. That football shape suggests the black hole is spinning at a substantial speed, which researchers estimated to be about 60% of its potential limit.

Nature's checkup: Surveying biodiversity with environmental DNA sequencing      (via sciencedaily.com)     Original source 

A thousand kilometers south of Tokyo, far into the largest ocean on Earth, lies a chain of small, volcanic islands -- the Ogasawara Islands. Nature has been able to develop on its own terms here, far from both humans and the warm Kuroshio current, which acts like a shuttle, moving marine species from Taiwan, over the Ryukyu Islands, and up the Pacific coast of mainland Japan. With upwards of 70 % of trees and many animal species being endemic to the archipelago, the islands have been dubbed 'the Galapagos of the East', as they are valuable as both a biodiversity hotspot and a cradle of scientific discovery.

Spy-satellite images offer insights into historical ecosystem changes      (via sciencedaily.com)     Original source 

New study advocates the use of more than one million declassified images for ecology and conservation. The images can offer better insights into the historical changes of ecosystems, species populations or changes in human influences on the environment dating back to the 1960s. Collaboration between ecologists, conservationists, and remote sensing experts is necessary to explore the full potential of the data.

Astronomers report oscillation of our giant, gaseous neighbor      (via sciencedaily.com)     Original source 

A few years ago, astronomers uncovered one of the Milky Way's greatest secrets: an enormous, wave-shaped chain of gaseous clouds in our sun's backyard, giving birth to clusters of stars along the spiral arm of the galaxy we call home. Naming this astonishing new structure the Radcliffe Wave, the team now reports that the Radcliffe Wave not only looks like a wave, but also moves like one -- oscillating through space-time much like 'the wave' moving through a stadium full of fans.

Giant Antarctic sea spiders reproductive mystery solved      (via sciencedaily.com)     Original source 

Instead of carrying the babies until they hatched, as in most species of sea spiders, one parent (likely the father) spent two days attaching the eggs to the rocky bottom where they developed for several months before hatching as tiny larvae.

Measuring neutrons to reduce nuclear waste      (via sciencedaily.com)     Original source 

Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is a concern. Radioactive waste products can be turned into more stable elements, but this process is not yet viable at scale. New research reveals a method to more accurately measure, predict and model a key part of the process to make nuclear waste more stable. This could lead to improved nuclear waste treatment facilities and also to new theories about how some heavier elements in the universe came to be.
