Flash thought to result from black hole swallowing a star Two separate teams of scientists, who have published papers in Nature and Nature Astronomy, have concluded that a flash of light that appeared in February was the astrophysical jet that erupted from a massive black hole as it swallowed a star. “From the data we […]

Are inorganic nanothreads possible? The case for borazine-based ones

Nanothreads are one-dimensional covalently bonded materials, with all “backbone” bonds saturated in the organic sense, the first of which was made from polymerization of benzene in the solid state. Nanothreads are thicker than conventional hydrocarbon polymers such as polyethylene and thinner than traditional nanowires: as ladder polymers, they are examples of the thinnest possible rigid […]

Ultraprecise entangled clocks

Ultraprecise entangled clocks

Quantum physics

By César Tomé

For the first time, scientists have entangled atoms for use as networked quantum sensors, specifically, atomic clocks and accelerometers. The research team’s experimental setup yielded ultraprecise measurements of time and acceleration. Compared to a similar setup that does not draw on quantum entanglement, their time measurements were 3.5 times more precise, and acceleration measurements exhibited […]

Preliminary research identifies brain changes associated with migraine

Preliminary research identifies brain changes associated with migraine

Neuroscience

Why some people get migraines while others don’t? New research indicates that it might be due to specific brain changes in migraine sufferers, particularly, in the centrum semiovale, a white matter region underneath the cerebral cortex. New data presented at the yearly meeting of the Radiological Society of North America points towards brain differences among […]

Best-explored planet outside our solar system WASP-39b, a boiling Saturn-like planet 700 light-years away from the sun has become the best-explored planet outside our solar system, as the James Webb Space Telescope’s observations have yielded a trove of information about the exoplanet’s atmosphere. Laura Kreidberg, director of the Max Planck Institute for Astronomy, said the […]

Usually, optical activity is understood as the ability some substances have to change the handedness of polarized light when it goes through them. Molecules that show optical activity have no plane of symmetry. So-called chiral matter broadly describes structures for which left- or right-handed mirror images are non-superimposable, or, equivalently, that lack improper rotation axes […]

Imagine an old-growth forest in the fading light of a summer evening. As the last of the sun’s rays disappear beneath the horizon, a tiny flash catches your eye. You turn around, hold your breath; it blinks again, hovering 2 feet above the leaf litter. Across the dusky glade, a fleeting response. Then another one […]
