Tunneling magnetoresistance in altermagnetic RuO₂-based magnetic tunnel junctions

Tunneling magnetoresistance in altermagnetic RuO₂-based magnetic tunnel junctions

A research team affiliated with UNIST announced the successful development of a novel semiconductor device that uses a new class of materials, known as altermagnetism. This breakthrough is expected to significantly advance the development of ultra-fast, energy-efficient AI semiconductor chips.

How a triatomic molecule works off excess energy

How a triatomic molecule works off excess energy

A resonance effect can significantly affect how a three-atom molecule cools down when excited, RIKEN physicists have found. The study, published in Physical Review A, highlights the complexity of the relaxation dynamics of even simple molecules.

Weaker Atlantic currents bring more oxygen to tropical ocean's shallow depths

Weaker Atlantic currents bring more oxygen to tropical ocean's shallow depths

How is ventilation at various depth layers of the Atlantic connected and what role do changes in ocean circulation play? Researchers from Bremen, Kiel and Edinburgh have pursued this question and their findings have now been published in Nature Communications.

Dogs' TV viewing habits vary by personality

Dogs' TV viewing habits vary by personality

The way household dogs engage with TV may depend on their personalities, suggests research published in Scientific Reports. Excitable dogs were more likely to follow on-screen objects while fearful or anxious dogs were more likely to respond to stimuli such as cars or a doorbell, with the dogs surveyed watching TV for an average of 14 minutes and eight seconds.

Scientists repurpose old solar panels to convert CO₂ exhaust into valuable chemicals

Scientists repurpose old solar panels to convert CO₂ exhaust into valuable chemicals

Centuries ago, alchemists worked furiously to convert the common metal lead to valuable gold. Today, chemists are repurposing discarded solar panels to create valuable organic compounds from carbon dioxide (CO2), a common greenhouse gas.

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.
