Astrophysicists discover a novel method for hunting the first stars      (via sciencedaily.com)     Original source 

A recent study has discovered a novel method for detecting the first-generations stars, known as Population III (Pop III) stars, which have never been directly detected. These potential discoveries about Pop III stars hold the promise of unlocking the secrets of the universe's origin and providing a deeper understanding of the remarkable journey from the primordial cosmos to the world we inhabit today.

Acceptance of animals in urban environments      (via sciencedaily.com)     Original source 

How do city residents feel about animals in their immediate surroundings? A recent study shows how different the acceptance of various wild animals in urban areas is. Important factors are the places where the animals are found and their level of popularity -- squirrels and ladybugs come out on top here. The results have important implications for urban planning and nature conservation.

Astronomers observe elusive stellar light surrounding ancient quasars      (via sciencedaily.com)     Original source 

Astronomers observed the elusive starlight surrounding some of the earliest quasars in the universe. The findings may shed light on how the earliest supermassive black holes became so massive despite having a relatively short amount of cosmic time in which to grow.

Hubble views a galaxy with a voracious black hole      (via sciencedaily.com)     Original source 

Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It's classified as a Seyfert galaxy, which means that it's an extremely energetic type of galaxy with an active galactic nucleus (AGN).

Oil palm plantations are driving massive downstream impact to watershed      (via sciencedaily.com)     Original source 

The global demand for palm oil -- the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick -- is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers have now shown the far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur.

To bend the curve of biodiversity loss, nature recovery must be integrated across all sectors      (via sciencedaily.com)     Original source 

The alarming rates of biodiversity loss worldwide have made clear that the classical way of governing biodiversity recovery based on protected areas and programs for the protection of endangered species is not enough. To tackle this, almost 200 countries committed to the active 'mainstreaming' or integration of biodiversity targets into policies and plans across relevant sectors. However, research suggests that this has until now been largely ineffective due to non-binding commitments, vaguely formulated targets, 'add-on' biodiversity initiatives, and too few resources. 'Top down regulation is also needed,' say the authors.
