    Frustrated fish get feisty

    View the videoFailing to get an expected snack rouses fish to fight with extra ferocity. The change in behavior is especially marked in undersized fish facing a big, scary opponent.The fish version of frustration can drive little fish to posture at and fight big fish that they would normally flee from, says Marco Vindas of the University of Oslo. Two of 11 of these overheated...

    Word-streaming tech may spell trouble for readers

    In the brave new digital world of reading, words flash by one at a time on the tiny screens of smart watches and phones. This portable, pageless story doesn’t end well for people keen on understanding what they’ve read, say psychologist Elizabeth Schotter of the University of California, San Diego and her colleagues.Rereading words salvages...

    How fractals jam glassy materials

    Unlike molecules in a crystal lattice, the molecules in glass don’t have regular positions, even though glass is a solid. Scientists think that glass molecules don’t flow, as they would in a liquid, because the particles are caged by each other and don’t have enough energy to overcome a threshold known as the energy...

    Farmers assimilated foragers as they spread agriculture

    Agriculture’s spread into Europe was a movement of people, not just ideas, new genetic data suggest.Early farmers living in Sweden about 5,000 years ago carried genetic signatures of both farmers and hunter-gatherers, researchers report April 24 in Science. The findings suggest that migrating farmers bred...

    Could the menstrual cycle have shaped the evolution of music?

    A piece of advice I once received: Don’t ever talk about your period at work. No one wants to know.I have broken that rule. Menstrual cycles are fascinating, and at the risk of a major breach of workplace etiquette, here’s why we should all be talking about them more: If you’re a woman, your cycle shapes your physiology more than you probably realize, with hormones orchestrating a monthly...

    Gene therapy with electrical pulses spurs nerve growth

    Electrical current from a cochlear implant has guided corrective genetic material into inner ear cells and stimulated nerve regeneration in deaf guinea pigs. The treatment improved the animals’ hearing sensitivity and range, researchers report April 24 in Science Translational Medicine. The gene therapy technique, which does...

    Enzyme may help aspirin protect against colon cancer

    Aspirin, the pain reliever that lowers fever and inhibits blood clotting, also shows impressive but spotty protection against colorectal cancer. A new study reveals that people who fail to get this benefit from the drug might be making too little of a key enzyme in the colon.Among aspirin users, those with ample levels of the enzyme 15-PGDH are about...

    Major step taken toward error-free computing

    Quantum computing has overcome an important barrier: Scientists have achieved nearly perfect control over a bit of quantum information in a way that could bring them a step closer to error-free calculations.All digital information comes in tiny packets called bits. In consumer devices, bits are chunks of magnetic or electric material that flip between two distinct states. But thanks to quantum...

    Secrets of a sailfish attack

    Many of us are familiar with sailfish — relatives of marlin— only from seeing them on the walls of sport fishermen. But watching them underwater, whether in person or on video, shows how beautiful the animals are in their natural habitat (...

    Dolphins use sponges to dine on different grub

    Some bottlenose dolphins sport cone-shaped sea sponges in their beaks, a behavior that may help the animals hunt. New research confirms the idea, showing that sponging dolphins have different fatty acids and therefore different diets than...
