Solar storms could be more extreme if they ‘slipstream’ behind each other

The 23 July 2012 event recorded by STEREO Modeling of an extreme space weather event that narrowly missed Earth in 2012 shows it could have been even worse if paired with another event. The findings ....

Insect Armageddon: Low doses of the insecticide, Imidacloprid, cause blindness in insects

Dr Felipe Martelli says studies have shown that low doses of insecticides can affect insect behaviour but have not uncovered how insecticides trigger changes at the cellular and molecular levels. Credit: Florienne Loder, Bio21 Institute, ....
