What colour were the dinosaurs? If you have a picture in your head, fresh studies suggest you may need to revise it. New fossil research also suggests that pigment-producing structures go beyond how the dinosaurs looked and may have played a fundamental role inside their bodies too.
Think back to what you did last weekend. You might be able to picture it clearly, but there should be no doubt in your mind that whatever you are remembering happened in the past. For people with post-traumatic stress disorder (PTSD), however, memories of traumatic events often return in the form of vivid flashbacks that make it feel like it’s happening all over again – putting them right back at the scene of a car crash, or the moment they lost a loved one.
Tapping into the genetic diversity contained within the seeds of wild relatives and forgotten crop plants could help farmers decrease their dependency on global agribusiness and grow food better suited to local conditions.
Neuroscientist Dr Domenica Bueti often plays an altered version of the classic aria La donna è mobile when she gives talks about the importance of time perception. Her friend’s piano rendition of Giuseppe Verdi’s composition uses the same notes but is played at different speeds. Rarely does anyone ever identify the tune.
Europeans can slash their fuel bills and have a significant impact on curbing global greenhouse gas emissions by buying more energy efficient cars, homes or even fridges – but many do not because of higher initial cost of green products, mistrust in EU energy ratings, and lack of awareness of long-term savings, researchers say.
Scientists are getting closer to understanding how to turn the body’s energy-storing white fat cells into energy-burning beige fat cells, opening up hopes that fat deposits could one day be deliberately manipulated to prevent obesity and related health conditions.
Little more than a decade ago, two astronomers discovered mysterious bursts of radio waves that seem to take place all over the sky, often outshining all the stars in a galaxy. Since then, the study of these fast radio bursts, or FRBs, has taken off, and while we still don’t know what exactly they are or what causes them, scientists are now edging closer to some answers.
The mysteries of an ancient civilisation that survived for more than a millennium on the island of Malta – and then collapsed within two generations – have been unravelled by archaeologists who analysed pollen buried deep within the earth and ancient DNA from skulls and bones.
By assembling a camera that can record video at nanometre resolution, scientists have filmed how the immune system kills bacteria by poking holes into it. Professor Georg Fantner tells us about how this was achieved and why his next challenge is to build a video camera that can film the inside of a living cell.
Removing immune-stimulating sugars should also help people with red meat allergies.
Newly domesticated horses may have increased the spread of disease.
