Researchers discover the universe's oldest stars in our own galactic backyard      (via sciencedaily.com)     Original source 

Astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way's 'halo' -- the cloud of stars that envelopes the entire main galactic disk -- and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape.

Island birds more adaptable than previously thought      (via sciencedaily.com)     Original source 

The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.

New light shed on carboxysomes in key discovery that could boost photosynthesis      (via sciencedaily.com)     Original source 

A research team has discovered how carboxysomes, carbon-fixing structures found in some bacteria and algae, work. The breakthrough could help scientists redesign and repurpose the structures to enable plants to convert sunlight into more energy, paving the way for improved photosynthesis efficiency, potentially increasing the global food supply and mitigating global warming.

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.

Limited adaptability makes freshwater bacteria vulnerable to climate change      (via sciencedaily.com)     Original source 

Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from European lakes, researchers uncovered specific evolutionary strategies that shape these bacteria's lifestyles. Understanding the evolutionary dynamics of aquatic microbial communities is key to safeguarding ecosystem services.

Genomes of 'star algae' shed light on origin of plants      (via sciencedaily.com)     Original source 

Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.

For microscopic organisms, ocean currents act as 'expressway' to deeper depths      (via sciencedaily.com)     Original source 

Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.
