Quantum computing enables simulations to unravel mysteries of magnetic materials

A multi-institutional team became the first to generate accurate results from materials science simulations on a quantum computer that can be verified with neutron scattering experiments and other practical techniques.

Collective worm and robot 'blobs' protect individuals, swarm together

Individually, California blackworms live an unremarkable life eating microorganisms in ponds and serving as tropical fish food for aquarium enthusiasts. But together, tens, hundreds, or thousands of the centimeter-long creatures can collaborate to form a "worm blob," a shape-shifting living liquid that collectively protects its members from drying out and helps them escape threats such as excessive heat.

School closures may not reduce coronavirus deaths as much as expected: study

School closures, the loss of public spaces, and having to work remotely due to the coronavirus pandemic have caused major disruptions in people's social lives all over the world.

Advanced simulations reveal how air conditioning spreads COVID-19 aerosols

The detailed physical processes and pathways involved in the transmission of COVID-19 are still not well understood. Researchers decided to use advanced computational fluid dynamics tools on supercomputers to deepen understanding of transmission and provide a quantitative assessment of how different environmental factors influence transmission pathways and airborne infection risk.

Read a Science Book, Learn Something New: Check Out 'Mind Thief,' 'Beloved Beasts' and 'A Thousand Ways Denied'

Dig into the quest to understand Alzheimer’s, the roots of the conservation movement, and the environmental legacy of the oil industry in Louisiana. Then, watch a new Netflix documentary highlighting the role of soil management in our planet's future.

ATLAS finds evidence of a rare Higgs boson decay

Since the discovery of the Higgs boson in 2012, scientists in the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) have been hard at work characterizing its properties and hunting down the diverse ways in which this ephemeral particle can decay. From the copious but experimentally challenging decay to b-quarks, to the exquisitely rare but low-background decay into four leptons, each offers a different avenue to study the properties of this new particle.

Shuffling bubbles reveal how liquid foams evolve

Foams are found everywhere, in soaps and detergents, meringues, beer foam, cosmetics and insulation for clothing and building. The application of foams tends to take advantage of their unique structure, which is why understanding how their structure can change over time is so important.

'Magnetic graphene' forms a new kind of magnetism

Researchers have identified a new form of magnetism in so-called magnetic graphene, which could point the way toward understanding superconductivity in this unusual type of material.

Researchers control a magnet's state by optically shaking its atomic lattice

An international team led by researchers of Delft University of Technology (TU Delft) has managed to manipulate the magnetic state of a magnetic material by optically shaking it. The whole process happens within an extremely short time frame of less than a few picoseconds. In times of stalling efficiency trends of current technology, such atomically-driven ultrafast control of magnetism opens broad new vistas for information technology.
