Organic compounds in asteroids formed in colder regions of space      (via sciencedaily.com)     Original source 

Analysis of organic compounds -- called polycyclic aromatic hydrocarbons (PAHs) -- extracted from the Ryugu asteroid and Murchison meteorite has found that certain PAHs likely formed in the cold areas of space between stars rather than in hot regions near stars as was previously thought. The findings open new possibilities for studying life beyond Earth and the chemistry of objects in space.

Astronomers detect seismic ripples in ancient galactic disk      (via sciencedaily.com)     Original source 

 A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way.   At more than 12 billion years old, BRI 1335-0417 is the oldest and furthest known spiral galaxy in our universe. The researchers were able to not only capture the motion of the gas around BRI 1335-0417, but also reveal a seismic wave forming -- a first in this type of early galaxy.

NASA's Hubble watches 'spoke season' on Saturn      (via sciencedaily.com)     Original source 

A new photo of Saturn was taken by NASA's Hubble Space Telescope on October 22, 2023, when the ringed planet was approximately 850 million miles from Earth. Hubble's ultra-sharp vision reveals a phenomenon called ring spokes.

Supernova encore: Second lensed supernova in a distant galaxy      (via sciencedaily.com)     Original source 

In November 2023, NASA's James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by the powerful gravity of the intervening galaxy cluster. In addition to warping and magnifying the distant galaxy, the gravitational lensing effect caused by MACS J0138 produces five different images of MRG-M0138.

How national policies affect forests in border regions      (via sciencedaily.com)     Original source 

How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.

Finding new ways to adapt to a growing weather threat      (via sciencedaily.com)     Original source 

Research reveals a steady increase in the number of people at risk from tropical cyclones and the number of days per year these potentially catastrophic storms threaten health and livelihoods. The findings could help relief agencies, development banks, and other organizations plan more effective strategies for mitigating extreme weather impacts.

Reduced air pollution during pandemic points to way to preserve Himalayan glaciers      (via sciencedaily.com)     Original source 

Reducing air pollution to levels similar to those during the coronavirus pandemic could protect the glaciers in the Himalayas and prevent them from disappearing by the end of the century. This is the conclusion reached by an international research team analyzing the situation during the COVID-19 lockdown in 2020.

World's smallest 'fanged' frogs found in Indonesia      (via sciencedaily.com)     Original source 

Researchers have identified a species of frog new to science. The Indonesian amphibian is the size of a quarter, unlike its two-pound cousins, and has tiny fangs. Nearly uniquely among amphibians, they lay their eggs on the leaves of trees, and the males guard and tend to the nests.

Ringing in the holidays with ringed planet Uranus      (via sciencedaily.com)     Original source 

NASA's James Webb Space Telescope recently trained its sights on unusual and enigmatic Uranus, an ice giant that spins on its side. Webb captured this dynamic world with rings, moons, storms, and other atmospheric features -- including a seasonal polar cap. The image expands upon a two-color version released earlier this year, adding additional wavelength coverage for a more detailed look.

Wildfires increasing across Eastern U.S.      (via sciencedaily.com)     Original source 

Researchers examined 36 years of wildfire data in the eastern United States, focusing on fires that burned large areas. The overall trend for the region showed an increase in fire size, frequency, and shifts in seasonality and highlights a need for proactive management and individual preparedness for those living in this populous part of the country.

15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems      (via sciencedaily.com)     Original source 

Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.
