Dinosaur snacked on seaweed washed up on North American coasts, fossil teeth suggest

Storms routinely wash marine material ashore, providing food for land animals and other organisms. This is known as marine subsidization (MS). Today, MS is particularly common in coastal ecosystems and is especially important to animals when land ecosystems produce less food than usual, such as during droughts. A new Frontiers in Ecology and Evolution study has shown that dinos and their prey, too, may have eaten seafood washed onto beaches.

Crystal spacing predicts magnetic states in complex alloys better than electron count

In materials chemistry, identifying common parameters that can organize magnetic ground states across complex intermetallic compounds remains a central challenge. Researchers have long used chemically tunable parameters to control magnetic properties. One is valence-electron concentration, commonly discussed as the electron-per-atom (e/a) ratio. The e/a ratio has been widely used to classify magnetic ground states in metallic systems such as Heusler alloys and approximant crystals.

Camera system sheds new light on bird collisions at sea

Research into bird collisions with offshore wind turbines has taken an important step forward. A yearlong pilot study at an offshore wind turbine has shown that thermal cameras and artificial intelligence can be used to directly observe potential collisions at sea. The technology proved effective under challenging conditions while also generating rare real-world data on bird movements around a wind turbine.

Small fields, great diversity: How a diverse patchwork of crops helps birds

Birds are not only beautiful to look at and listen to; they also play important roles in nature. They eat pests and disperse seeds. They are generally considered indicators of a healthy environment. When birds thrive, soil and water quality often benefit as well. A new study published in the journal Landscape Ecology shows that growing a variety of crops in small field patches creates better habitats for birds.

Physics-grounded AI framework aims to make predictions about new materials more testable

Artificial intelligence is increasingly being used to discover new materials, but conventional data-driven approaches can struggle to explain their predictions, work reliably beyond their training data and remain consistent with physical laws. A new perspective proposes a framework called Physics-Grounded Materials AI (PhysMat AI), which integrates fundamental physical knowledge into the materials discovery process. The research is published in the journal Advanced Functional Materials.

New index links changing ocean food webs to Bermuda

Spiny lobster larvae spend six to nine months drifting in the open ocean, feeding within the plankton community, before eventually settling into shallow-water habitats such as mangroves, seagrass beds or coral reefs. This means the number of young lobsters reaching Bermuda is strongly influenced by ocean conditions across the wider North Atlantic and Caribbean region.

LISA to the rescue: Using light to fix cell division

Cell division is a complex process. At the heart of this complexity is a membraneless organelle called the centrosome, which is made up of more than 200 components. It is responsible for clustering mitotic spindles, threadlike structures needed to separate genetic material. It has long remained unclear which parts of the centrosome are necessary and sufficient for spindle assembly.

Protein signaling cascade helps explain how plants respond to touch

Plants cannot run away when the wind picks up, rain lashes down or a hungry herbivore begins chewing on their leaves. Instead, they must sense their surroundings and adapt. Now, researchers have uncovered an important piece of the puzzle of what happens inside plants when they are exposed to touch, injury or other physical stimuli.

New feathered, winged dinosaur from China challenges our theories on bird and dinosaur evolution

A newly described feathered dinosaur found in northeastern China adds evidence supporting the theory that flight-related features evolved differently in various bird-like dinosaur groups. The findings, reported in Nature Communications, are based on an analysis of an exceptionally well-preserved fossil of a microraptorine (a small dinosaur with feathers and wings) found in a geological formation estimated to be between 145 and 100 million years old.

Arctic infrastructure was built on frozen ground

From the air, Wainwright, Alaska, looks like a perfectly stable band of homes and roads between the Chukchi Sea and a vast, flat tundra. But just below the surface, the frozen ground on which this town was built contains large bodies of ice. Along the eroding coastal bluffs, that hidden ice is becoming exposed and melting away.

Mysterious giant carving may show a Kushite ruler and mark an ancient borderland

For centuries, a life-size petroglyph has stood over the rocky landscape of Miseeda in northern Sudan. Exactly who the figure carved into a granite hill represents remains uncertain, but researchers suspect it may depict an ancient Kushite ruler. In the 7th century CE, local builders constructed a Christian church directly around it.

How the moon and sun may trigger slow earthquakes on Earth

While not quite a fatal attraction, the gravitational pull of the moon and sun creates tiny stresses on Earth that can trigger events known as slow earthquakes. These are movements along fault lines (fault slips) that release their energy gradually over much longer periods than ordinary quakes. Although they have been observed, exactly how these celestial bodies trigger them has been a relatively tough nut to crack.
