A study has found that an ancient protein motif that binds to nucleic acids is functionally "ambidextrous." This means that the motif can interact with both natural and mirror-image nucleic acids, an occurrence that has never ...

A team of researchers led by Niccolò Maffezzoli, "Marie Curie" fellow at Ca' Foscari University of Venice and the University of California, Irvine, and an associate member of the Institute of Polar Sciences of the National ...

The Amazon rainforest may be able to survive long-term drought caused by climate change, but adjusting to a drier, warmer world would exact a heavy toll, a study published in Nature Ecology and Evolution suggests.

Together, or not together, that is the question. Hamlet is not the only one facing life-changing questions—wild animals have to make decisions pivotal to their survival on a daily basis.

Using advanced technology that analyzes tiny gas bubbles trapped in crystals, a team of scientists led by Cornell University has precisely mapped how magma storage evolves as Hawaiian volcanoes age.

Researchers have created a new kind of nanoparticle that could make ultrasound-based cancer treatments more effective and safer, while also helping prevent tumors from coming back.

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the hypothetical force shaping ...

Sun filters through dense stands of cycads and conifers of Gondwana, where a lithe, bipedal predator slowly moves through the Upper Triassic undergrowth. Standing just over a meter tall and measuring about two meters from ...

Using a set of ground-based radio telescopes, an international team of astronomers has observed a slowly-spinning pulsar known as PSR J0901−4046. Results of the observational campaign, published on the arXiv preprint server, ...

Engineers at NASA's Jet Propulsion Laboratory in Southern California have revived a set of thrusters aboard the Voyager 1 spacecraft that had been considered inoperable since 2004. Fixing the thrusters required creativity ...

Archaeopteryx is the fossil that proved Darwin right. It's the oldest known fossil bird, and it helps show that all birds— including the ones alive today—are dinosaurs. And while the first Archaeopteryx fossil was found ...

On March 15, 2024, near the peak of the current solar cycle, the sun produced a solar flare and an accompanying coronal mass ejection (CME), a massive explosion of gas and magnetic energy that carries with it large amounts ...
