    Vacuum method identifies animals with DNA in the air

    A new technique that involves vacuuming animal DNA from the air can ID nearby species. It could help map threatened and invasive species.

    85% of laying hens have broken keel bones

    Researchers examined over 4,000 laying hens to find widespread broken keel bones. The culprit, they say, are too large eggs and too small hens.

    Genomes debunk the idea of blond, Nordic Vikings

    Researchers sequenced the genome of 442 Viking Age bone fragments from all over Europe. The Vikings may not have been quite as Nordic as we thought.

    ‘Steering wheel’ neurons control left and right turns in mice

    A new discovery that sheds light on how neurons control whether mice turn right or left while walking could prove useful for people with motor disorders.

    1 enzyme is key for successful fertilization

    One enzyme may determine whether human development starts correctly. The discovery could help explain why some fertilization fails.

    Oldest human genetic data may expand our ‘family tree’

    The oldest human genetic data ever recovered could shed light on the evolution of our ancestors and clarify the branches of the human family tree.

    Team maps how brain signals trigger pain

    A new discovery of how a potent neuropeptide binds to a brain receptor involved in causing human pain could lead to new painkilling medications.

    Infections during pregnancy may hamper fetal brain development

    Infections during pregnancy are a risk factor for offspring developing disorders like schizophrenia and autism. Now researchers have figured out why.

    ‘Atlas’ of the body’s sugars could shed light on disease

    An "atlas" of the sugars that cover human cells stands to benefit investigations into viral and bacterial infections.

    Morning exercise or evening? Both have perks

    The benefits of morning exercise and evening workouts differ, research in mice shows. But that doesn't necessarily mean one is better.

    ‘Scanner’ directs DNA repairs to protect against cancer

    When the DNA repair system isn't working in our cells, our risk of cancer may go up.
