Newly discovered “swirlonic state” of matter bends the laws of physics

Researchers have discovered a new kind of active matter that bends the laws of physics. Dubbed “swirlon,” the new matter behaves similarly to how fishes swim in schools and birds fly in murmurations. The laws of physics apply to passive, nonliving matter, ranging from planets all the way down to the smallest atoms. But according to Nikolai Brilliantov, a mathematician … Continue reading Newly discovered “swirlonic state” of matter bends the laws of physics

Scientists use nanoparticles as an alternative propulsion method for small spacecraft

Propellant is one of the most important things that any spacecraft needs to carry – without it, a spacecraft will be unable to move or change course. This is why spacecraft tend to carry a lot of it on board. Carrying propellant, however, brings its own set of problems. Not only is the chemical highly flammable, … Continue reading Scientists use nanoparticles as an alternative propulsion method for small spacecraft

Aerosol transmission of coronavirus underestimated, study says

New research is warning that the aerosol transmission of the Wuhan coronavirus (COVID-19) is being underestimated, possibly affecting guidelines on social distancing, ventilation and shared spaces. Using a newly developed mathematical model of coronavirus droplet migration, researchers at the Heriot-Watt University and the University of Edinburgh have found that small, virus-laden aerosol particles are traveling further than expected. “The flow physics of someone … Continue reading Aerosol transmission of coronavirus underestimated, study says

Research: Strange behavior of Earth’s magnetic field in the South Atlantic believed to be symptoms of an event that repeats every few million years

The Earth is protected from solar wind — a stream of charged particles from the sun — by its geomagnetic field. But this protective barrier is weak in certain areas, particularly south of the Atlantic Ocean. Called the South Atlantic Anomaly (SAA), this area makes it easier for solar wind and other cosmic rays to enter the … Continue reading Research: Strange behavior of Earth’s magnetic field in the South Atlantic believed to be symptoms of an event that repeats every few million years
