Phys.org / New code helps scientists map dark matter halos
Dark matter and its impact on cosmology have puzzled physicists for nearly a century. At Perimeter Institute, two researchers are trying to better understand how one potential dark matter candidate, self-interacting dark ...
Phys.org / New magnetic sensor material discovered using high-throughput experimental method
A NIMS research team has developed a new experimental method capable of rapidly evaluating numerous material compositions by measuring anomalous Hall resistivity 30 times faster than conventional methods. By analyzing the ...
Phys.org / A new possibility for life: Study suggests ancient skies rained down ingredients
Earth's atmosphere might have contributed to the origin of life more than previously thought. In a study published in the Proceedings of the National Academy of Sciences, CU Boulder researchers and collaborators reveal that ...
Phys.org / On-demand electronic switching of topology achieved in a single crystal
University of British Columbia (UBC) scientists have demonstrated a reversible way to switch the topological state of a quantum material using mechanisms compatible with modern electronic devices. Published in Nature Materials, ...
Phys.org / Scientists map Mars' large river drainage systems for first time
Billions of years ago, it rained on Mars. The water collected in valleys and rivers, filled and spilled over the rims of craters, and was funneled into canyons, perhaps even making its way to a large Martian ocean.
Phys.org / Elephant seals recognize their rivals from years prior, study finds
Humans are not the only animals that can remember the voices of their old acquaintances. Elephant seals, too, can remember the calls of their rivals even a year later.
Dialog / Dislocations without crystals: Burgers vectors discovered in glass
For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, which move through ...
Phys.org / Durable plastics made from essential oil compounds offer easy recycling
Cheap, strong, and versatile, plastic seemed like the perfect invention—until its staying power turned into a global headache. Now, Yokohama National University researchers have developed a plant-based alternative that ...
Phys.org / Noise-proof quantum sensor uses three calcium ions held in place by electric fields
Researchers at the University of Innsbruck have shown that quantum sensors can remain highly accurate even in extremely noisy conditions. It's the first experimental realization of a powerful quantum sensing protocol, outperforming ...
Phys.org / Earth's rapid warming 56 million years ago left plants struggling to keep up
Around 56 million years ago, Earth suddenly got much hotter. Over about 5,000 years, the amount of carbon in the atmosphere drastically increased and global temperatures shot up by some 6°C.
Phys.org / Humpback whales are making a comeback—here's one reason why
When University of Southern Denmark whale researcher Olga Filatova set off on her first field trip in 2000, she spent five years looking for whales before she saw a humpback.
Phys.org / Massive pit circle confirmed as Neolithic structure near Durrington Walls henge
New research from the University of St Andrews, as part of a team led by the University of Bradford, has confirmed the details of a massive, neolithic pit structure recently discovered during a geophysical survey around the ...
