Humans are getting older and older, and the number of people with dementia is increasing. The factors controlling degeneration of the brain are still mostly unknown. However, researchers assume that factors such as stress, accumulation of toxic waste products as well as inflammation accelerate aging. But, vice versa, there are also mechanisms that can - like a bodyguard - protect the brain from degenerating, or repair defective structures.

These are various types of potatoes that are grown in Peru. These potatoes differ in shape, skin pigmentation and flesh pigmentation. An international consortium of scientists has produced a new map of the potato genome that may lead to the development of an ultra-nutritious potato that could help feed the world's hungry.

Research has shown that light is the key to getting our 'body clocks' back in sync and now a new study exploring the resynchronisation mechanism in insects has discovered a molecule essential to the process.

Three small primitive mammals walk over a Triceratops skeleton, one of the last dinosaurs to exist before the mass extinction that gave way to the age of mammals. A team of scientists has discovered the youngest dinosaur preserved in the fossil record before the catastrophic meteor impact 65 million years ago. The finding indicates that dinosaurs did not go extinct prior to the impact and provides further evidence as to whether the impact was in fact the cause of their extinction.
