Microplastics hinder plant photosynthesis, study finds, threatening millions with starvation. Between 4% and 14% of the world’s staple crops of wheat, rice and maize is being lost due to the pervasive particles. It could get even worse, as more micro plastics pour into the environment

The megalodon has long been imagined as an enormous great white shark, but new research suggests that perception is all wrong. The study finds the prehistoric hunter had a much longer body—closer in shape to a lemon shark or even a large whale.

Firefighters could be exposed to chemicals that put them at higher brain cancer risk. Haloalkanes, in flame retardants and fire extinguishers, have been linked to gliomas. Firefighters, and people in jobs such as car painting and machine maintenance, are at higher risk of haloalkane gene mutations.

People on Wegovy or Ozempic find weight loss plateaus after losing 20-25% of body weight because the body responds by slowing down metabolism, burning fewer calories. Scientists discover in mice that they can turn off a gene so that the body doesn’t realize it is fasting and continues burning sugar.
