'Mobile' DNA elements may have expanded gene regulatory networks in brain development

Scientists have uncovered evidence supporting a mechanism in which transposable elements (TEs), once considered "non-functional" DNA, may have contributed to the evolution and expansion of gene regulation during neural development. ...

DNA 'barcodes' help researchers pinpoint gold nanoparticles that can strike cancer at its power source

Researchers at the National University of Singapore (NUS) have developed a high-throughput method to identify gold nanoparticles capable of delivering therapies directly to mitochondria (the energy centers inside cancer cells). ...

Climate change: How oxygen deficiency changes metabolic processes in the ocean

The world's oceans are losing oxygen—and rapidly. The principal cause is the increasing warming of the oceans, which reduces the solubility of oxygen in water and increases respiratory activity. In addition, it strengthens ...

Metagenomics and AI could unlock uncultivated bacteria and archaea

Advances in DNA sequencing have expanded our view of the microbial world, but the inability to cultivate most microbes has been a major constraint. Now, a systematic, predictive framework that combines existing genomic and ...

Looped polymers unlock stronger, faster molecular binding through entropy, model suggests

Entropy gets a bad rap. Typically associated with randomness and chaos, it can also correlate with freedom and diversity. Cornell researchers have found that, thanks to the latter qualities, entropy can help bind certain ...

Beneath seagrass meadows, a shift in warming seas could decide which underwater habitats survive

On the western side of Lake Macquarie in New South Wales, Australia, sits Myuna Bay, a quiet bay with meadows of seagrass waving beneath the water. The most common marine plant species you find there is Zostera muelleri. ...

Under mushroom caps, 17-plus bacterial species help drive stubborn blotch disease

A University of Florida study has made a key discovery in understanding a disease that for over a century has plagued the white button mushroom—a nutrient-dense vegetable that is valued for its versatility and health benefits. ...

How river DNA can track fish, frogs, fungi and human feces all at once

A single scoop of water from an Irish river has revealed evidence not only of Ireland's only frog species—as expected—but also signs of the dreaded B. dendrobatidis fungus, marking the first time this devastating amphibian ...

Genetics link Angola's 'ghost elephants' to populations hundreds of miles away

For more than a decade, conservation biologist Steve Boyes searched for "ghost elephants"—nocturnal giants rumored to roam a remote, high-altitude wetland in eastern Angola. When a motion-sensor camera finally captured their ...
