Phys.org / Nanoscale multiferroic materials open the path to efficient magnetic memory technology
With the rapid spread of cloud computing, artificial intelligence and data centers, global energy consumption is rising to new heights. A promising way to reduce this burden is to develop memory devices that store information ...
Phys.org / Built to last or break down: Ring size tunes biodegradable plastic lifetimes
Biodegradable plastics should be tough enough for use yet able to break down at an appropriate rate afterward. Researchers at the University of Osaka show that changing the size of rings threaded onto a biodegradable polymer ...
Phys.org / Predictive tools can confuse rare mutations with dangerous ones
When a patient's DNA is read, it is compared with a reference version of the human genome. This allows geneticists and rare disease experts to look at a list of places where the patient's DNA differs. Most variations will ...
Phys.org / Heat has a memory—and a new theoretical framework can track it
Heat, it turns out, has a memory. A cooling cup of coffee may not seem particularly thoughtful. At the scale of a kitchen, heat appears to follow a straightforward rule: it moves from warmer places to cooler ones. Leave the ...
Phys.org / BESIII sets world's most stringent direct limit on Lambda hyperon electric dipole moment
The BESIII Collaboration, led by the Institute of High Energy Physics of the Chinese Academy of Sciences, has achieved the world's most precise measurement of the electric dipole moment (EDM) of the Lambda (Λ) hyperon using ...
Phys.org / Permafrost melt could cost $261 billion in infrastructure damages, study suggests
A new study provides insight into the economic impact of melting permafrost on Arctic communities. Permafrost is ground that permanently remains below freezing for at least two consecutive years. Permafrost covers about 24% ...
Phys.org / Ancient DNA suggests western farming reached Gansu without mass migration
A multidisciplinary study has answered key questions about how agricultural practices diffused into ancient Gansu from Eurasia, as well as described population movements and burial practices in the Gansu region thousands ...
Phys.org / Wrinkled or smooth? Cell growth mechanics determine shape of plant organs
When inner and outer cell layers of sepals—the leaf-like plant organs that cover and protect the flower bud before it opens—all grow upward, the organs stay smooth and uniformly stiff, which is optimal for the plant, according ...
Phys.org / Chimpanzees have accents too, study finds
A study has found that young chimpanzees develop distinct population-specific vocal patterns as they mature (ontogeny), challenging the long-held assumption that their calls are inflexible and determined solely by genetics. ...
Phys.org / First switchable graphene nanoribbon that twists on demand
Researchers at Nagoya University have built a graphene nanoribbon that can switch the direction of its twist using a natural solvent. Graphene nanoribbons are thin, ribbon-shaped structures made of fused carbon rings. Twisted ...
Phys.org / Scientists solve years-long mystery of 'beating' signal in a quantum material
A team of Korean researchers has become the first in the world to identify the origin of the "beating" signal that has long been a major obstacle to interpreting quantum signals in topological insulator (TI) nanowires. Their ...
Phys.org / Electron spin unlocks magnetic control of hydrogen surface reactions
Chemical reactions at surfaces play a central role in many processes, including catalysis and materials synthesis. It is well known that the outcome of these reactions is influenced by the translational, vibrational and rotational ...
