Who eats the invaders?

Native Mediterranean species have been found to prey on the invasive Pacific red lionfish and silver-cheeked toadfish, suggesting direct human management measures are needed to control their populations. The study documents native predators for both species, including loggerhead turtles and dolphinfish.

From the Sun to the stars

The newly launched NEID spectrometer will measure the minute gravitational tug of planets on their host stars, enabling the detection of rocky planets and characterization of exoplanetary atmospheres. By utilizing this technology, scientists aim to push the boundaries for searching smaller exoplanets and probing beyond past challenges.

Solar cells: Layer of three crystals produces a thousand times more power

Researchers at Martin-Luther-University Halle-Wittenberg created a new material by combining barium titanate, strontium titanate, and calcium titanate in a lattice. The resulting ferroelectric-paraelectric superlattice significantly enhances the photovoltaic effect, producing up to 1,000 times more power than pure barium titanate.

Fish friends help in a crisis

A recent study by Nova Southeastern University found that schools of coral reef fish react more slowly to predators when surrounded by strangers, increasing the risk of being eaten. In contrast, familiar friends trigger a faster response, indicating trust and improved information sharing among neighboring fish.
