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.

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.

More Texas owls are testing positive for rat poisons      (via sciencedaily.com) 

New research suggests that owls in Texas have high rates of anticoagulant rodenticides (AR) -- blood thinning rat poisons -- in their systems.

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.

Plant-based food alternatives could support a shift to global sustainability      (via sciencedaily.com) 

Replacing 50% of meat and milk products with plant-based alternatives by 2050 can reduce agriculture and land use related greenhouse gas (GHG) emissions by 31% and halt the degradation of forest and natural land, according to new research.

Ecology and artificial intelligence: Stronger together      (via sciencedaily.com) 

Many of today's artificial intelligence systems loosely mimic the human brain. In a new paper, researchers suggest that another branch of biology -- ecology -- could inspire a whole new generation of AI to be more powerful, resilient, and socially responsible. The paper argues for a synergy between AI and ecology that could both strengthen AI and help to solve complex global challenges, such as disease outbreaks, loss of biodiversity, and climate change impacts.

Art, science merge in study of 19th-century landscape paintings' ecological integrity      (via sciencedaily.com) 

A collaboration of ecologists and art historians has demonstrated that landscape paintings from more than 150 years ago can advance environmental science.

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.

Scientists find evidence of sea star species hybridization      (via sciencedaily.com) 

A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.

Study hints at the existence of the closest black holes to Earth in the Hyades star cluster      (via sciencedaily.com) 

A new article hints at the existence of several black holes in the Hyades cluster -- the closest open cluster to our solar system -- which would make them the closest black holes to Earth ever detected.

Lack of evidence hampers progress on corporate-led ecosystem restoration      (via sciencedaily.com) 

An international team of scientists analysed publicly available sustainability reports released by 100 of the world's largest companies and found that around two-thirds of these global corporations are undertaking ecosystem restoration. However, the results highlight that despite many businesses claiming to actively rebuild damaged ecosystems, we know very little about what is actually being achieved.

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.

New cosmological constraints on the nature of dark matter      (via sciencedaily.com) 

New research has revealed the distribution of dark matter in never before seen detail, down to a scale of 30,000 light-years. The observed distribution fluctuations provide better constraints on the nature of dark matter.

Large herbivores keep invasive plants at bay      (via sciencedaily.com) 

Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.
