Machine learning puts a new spin on spin models

Tokyo, Japan - Researchers from Tokyo Metropolitan University have used machine learning to study spin models, used in physics to study phase transitions. Previous work showed that image/handwriting classifying AI could be applied to distinguish states in the simplest models. The team showed the approach is applicable to more complex models and found that an AI trained on one model and applied to...

Quantum copycat: Researchers find a new way in which bosons behave like fermions

Bosons and fermions, the two classes into which all particles—from the sub-atomic to atoms themselves—can be sorted, behave very differently under most circumstances. While identical bosons like to congregate, identical fermions tend to be antisocial. However, in one dimension—imagine particles that can only move on a line—bosons can become as stand-offish as fermions, so that no two...

SpaceX wins NASA contract to send cargo to lunar Gateway with new Dragon XL craft

NASA has tapped a type of SpaceX cargo craft that hasn't yet been built to deliver supplies to a moon-orbiting outpost that hasn't yet been launched. SpaceX's robotic Dragon XL, a cylindrical, supersized version of its workhorse Dragon spacecraft, will handle shipments to the Gateway space platform as the first commercial provider to receive a Gateway Logistics Services contract from...

In Earth's largest extinction, land animal die-offs began long before marine extinction

Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a long, perhaps 400,000-year period of extinction on land...

Coronavirus and volunteering: how can I help in the UK?

From lending a hand to local charities to bolstering the efforts of the NHS, there are many ways to get involvedAll our coronavirus coverageI want to help. Where can I find about about volunteering?There are plenty of ways to get involved. Many local charities will be keen to attract new volunteers – especially as older stalwarts are forced to stay at home. Or there are national schemes, such as...

Copper boosts pig growth, and now we know why

Pigs have better feed conversion rates with copper in their diets, but until now, scientists didn't fully understand why. Existing research from the University of Illinois shows copper doesn't change fat and energy absorption from the diet. Instead, according to new research, the element seems to enhance pigs' ability to utilize fat after absorption, resulting in increased energy utilization of...

A lifesaving reason to have more women on boards: ensuring consumer safety

In a study published online yesterday focused on the medical products industry—which includes medical devices, pharmaceuticals and biologics—a group of researchers found that, compared to firms with all-male boards, firms with female directors announced high-severity product recalls 28 days sooner. This is a 35% reduction in the time between when a firm was first made aware of the defect and...

Bubbles go with the flow: Simulating behavior of fluids moving through pipes

Researchers at the Institute of Industrial Science, The University of Tokyo, used a sophisticated physical model to simulate the behavior of fluids moving through pipes. By including the possibility of shear-induced bubble formation, they find that, contrary to the assumptions of many previous works, fluids can experience significant slippage when in contact with fixed boundaries. This research...

Multi-stage deformation process in high-entropy alloys at ultra-low temperatures revealed

An international research team led by scientists from City University of Hong Kong (CityU) has recently discovered that high-entropy alloys (HEAs) exhibit exceptional mechanical properties at ultra-low temperatures due to the coexistence of multiple deformation mechanisms. Their discovery may hold the key to designing new structural materials for applications at low temperatures.

Researchers take a big step towards a comprehensive single-cell atlas

A large team of researchers affiliated with multiple institutions in and around Hangzhou, China, has taken a very large step toward the creation of a comprehensive human single-cell atlas. In their paper published in the journal Nature, the group describes how they sequenced the RNA of over a half-million single cells donated by volunteers and processed the information to present it in a way that...

Researchers catch light in a funnel

Professor Ronny Thomale holds a chair for theoretical condensed matter physics, the TP1, at the Julius-Maximilian University of Würzburg. The discovery and theoretical description of new quantum states of matter is a prime objective of his research. "Developing a theory for a new physical phenomenon which then inspires new experiments seeking after this effect is one of the biggest moments in a...

Animals keep viruses in the sea in balance

A variety of sea animals can take up virus particles while filtering seawater for oxygen and food. Sponges are particularly efficient. That was written by marine ecologist Jennifer Welsh from NIOZ this week, in a publication in Nature Scientific Reports. This Monday, Welsh will defend her thesis at the Free University of Amsterdam, through an online connection.
