Tech Xplore / New memristor design uses built-in oxygen gradient to bring stability to reinforcement learning
In a recent study published in Nature Communications, researchers created a memristor that uses a built-in oxygen gradient to produce slow, stable conductance changes, enabling a reinforcement learning (RL) algorithm to learn ...
Phys.org / Quantum coherence could be preserved at large scales in realistic environments
Quantum states are notoriously fragile, and can be destroyed simply through interactions, measurements, and exposure to their surrounding environments. In a new theoretical study published in Physical Review X, Rohan Mittal ...
Phys.org / The secrets of black holes and the Higgs mass could be hidden in a 7-dimensional geometry
One of the greatest mysteries of modern physics, the "black hole information paradox," might have finally found an elegant solution, and the answer could also reveal the origins of the mass of fundamental particles.
Medical Xpress / How an Alzheimer's risk gene disrupts brain circuits long before memory loss
For the millions of people who carry the gene APOE4, the strongest known genetic risk factor for Alzheimer's disease, their brain activity may begin changing long before any memory problems appear. Now, researchers at Gladstone ...
Phys.org / Bumblebees can perceive rhythm, despite their brains being the size of a sesame seed
Humans are creatures of rhythms. As far as we know, humans have always sung and always danced. We can recognize a song by its rhythm alone, regardless of whether it is played fast or slow.
Tech Xplore / Rivalry and collaboration attitudes: Study finds writers need both to thrive in the age of AI
When a screenwriter told New York University researchers last year that letting AI do her work would make her "miserable inside," she was onto something. A follow-up study from NYU's Tandon School of Engineering and Stern ...
Phys.org / Ytterbium atomic clock could open a new window on fundamental physics
For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and extremely sensitive to ...
Tech Xplore / Waste water to clean energy: Japanese engineers harness the power of osmosis
A Japanese water plant is harnessing the natural process of osmosis to generate renewable energy that could one day become a common power source.
Phys.org / Engineered tobacco plant can produce five psychedelics, including psilocybin and DMT
Compounds in psychedelic drugs like DMT, psilocybin, and psilocin are naturally produced in certain plants, fungi, and animals, and have a long history of use in spiritual and therapeutic contexts. Now, a considerable amount ...
Phys.org / Artemis II astronauts rocket toward the moon after spending a day around Earth
NASA's Artemis II astronauts fired their engines and blazed toward the moon Thursday night, breaking free of the chains that have trapped humanity in shallow laps around Earth in the decades since Apollo.
Phys.org / Gravity from positivity: Single massive spin-3/2 particle makes gravity logically inevitable, study claims
Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles ...
Phys.org / How the octopus uses its 'taste by touch' sensory system to feel out potential mates
A new study by Harvard biologists reveals how octopuses feel their way to potential mates with a "taste by touch" sensory system and can even couple at arm's length without actually seeing each other. In a study featured ...
