Butterflies that look alike, see alike: Research links rainforest light to butterfly vision evolution

Butterflies that look alike, see alike: Research links rainforest light to butterfly vision evolution

Butterflies that independently evolved the same wing patterns have also evolved similar eyes and brains which are fine-tuned for vision in the shifting light of tropical rainforests, according to new research led by the University of Bristol published in Proceedings of the National Academy of Sciences this week.

Programmable DNA moiré superlattices: Expanding the material design space at the nanoscale

Programmable DNA moiré superlattices: Expanding the material design space at the nanoscale

Researchers are creating new moiré materials at the nanometer scale using advanced DNA nanotechnology. DNA moiré superlattices form when two periodic DNA lattices are overlaid with a slight rotational twist or positional offset. This creates a new, larger interference pattern with completely different physical properties.

New study tackles dynamics of common—and difficult—sailing maneuver

New study tackles dynamics of common—and difficult—sailing maneuver

Tacking—a maneuver used to sail a boat against the wind, changing direction in a zig-zag fashion—is one of the most difficult but necessary sailing maneuvers. While tacking is common, the movement of the sails and wind forces during the turn are not well understood.

Historical and current population DNA reveals at least 12 species of rocket frogs, three of which already extinct

Historical and current population DNA reveals at least 12 species of rocket frogs, three of which already extinct

A group led by University of São Paulo (USP) researchers in Brazil has described a new genus of frogs, Dryadobates, also known as rocket frogs, which was previously considered a single species. The study was published in the Bulletin of the American Museum of Natural History.

Scientists successfully develop half metal material that conducts single-spin electrons

Scientists successfully develop half metal material that conducts single-spin electrons

Researchers at Forschungszentrum Jülich have successfully created the world's first experimentally verified two-dimensional half metal—a material that conducts electricity using electrons of just one spin type: either "spin-up" or "spin-down." Their findings, now published as an Editors' Suggestion in Physical Review Letters, mark a milestone in the quest for materials enabling energy-efficient spintronic that go beyond conventional electronics.

On the origins of life: Metabolic activity successfully incorporated into synthetic cell membranes

On the origins of life: Metabolic activity successfully incorporated into synthetic cell membranes

At some point during the evolution of life on Earth, inorganic matter became organic, nonliving matter became living. How this happened is one of humankind's greatest mysteries. Today, scientists work to develop synthetic cells that mimic living cells, hoping to uncover clues that will help answer the question: how did life on Earth begin?

Magellanic penguins may use currents to conserve energy on long journeys

Magellanic penguins may use currents to conserve energy on long journeys

Currents can affect marine animals' locomotion, energy expenditure and ability to navigate; the force of currents may cause them to drift off-course of their intended trajectory.

Iron oxide behavior under pressure may reduce reliance on rare-earth metals in consumer, energy and medical tech

Iron oxide behavior under pressure may reduce reliance on rare-earth metals in consumer, energy and medical tech

Researchers at The University of Texas at Arlington have discovered a surprising new type of magnetic property that could lead to stronger magnets made from tiny particles of common iron oxide. This finding could enhance the performance of everyday technologies while reducing the need for rare-earth metals—materials that are more costly, less sustainable and harder to obtain.
