New telescope to detect gravitational wave events

Credit: Monash University A new telescope, made up of two identical arrays on opposite sides of the planet, will track down sources of gravitational waves. The Gravitational-wave Optical Transient Observer (GOTO), led by the University of Warwick, signals a new era of gravitational wave science. Deployed across two antipodal locations to fully cover the sky, … Read more

Climate change and land-use changes increase the likelihood of flood events

A year has passed since the flood disaster in the Eifel region, where the flood damaged or destroyed over 100 bridges.

Extreme weather, climate events may lead to an increase in violence towards women, girls, and sexual and gender minorities

Credit: CC0 Public Domain As the climate crisis leads to more intense and more frequent extreme weather and climate-related events, this in turn risks increasing the amount of gender-based violence experienced by women, girls, and sexual and gender minorities, say researchers. In a study published in The Lancet Planetary Healtha team led by a researcher … Read more

Discovery of ‘ghost’ fossils reveals plankton resilience to past global warming events
