Magnetic fields implicated in the mysterious midlife crisis of stars

New research reveals that magnetic fields of middle-aged stars become sub-critical, leading to reduced angular momentum losses and altered magnetic field strengths. This phenomenon breaks the relationship between a star's age and its rotation rate, allowing for a diversity of solar-stellar phenomena.

Study shows why beer mats do not fly in a straight line

Physicists investigated why beer mats behave strangely when thrown. The study found that the mat tips backwards due to gravity, creating an angle of attack that generates lift in the airflow. When rotated like a frisbee, the lifting force causes the mat to drift off to the side, rather than flying straight.

Oxygen-vacancy-mediated catalysis boosts direct methanation of biomass

Researchers developed an efficient method for direct methanation of lignocellulosic biomass using Ru/TiO2 catalysts, achieving selectivity above 95% at temperatures below 200°C. The oxygen-vacancy-mediated catalysis process couples biomass oxidation with hydrogenation to produce biomethane.

Scientists use tiny bubbles to help treat common childhood cancer

Researchers at University College London Great Ormond Street Institute of Child Heath have developed a new way to deliver drugs that can shut down cancer-promoting mutations in neuroblastoma. The nanoparticle-based treatment successfully silenced the MYCN gene, causing tumours to grow at a slower pace and prolonging survival.
