    Bacteria triggers material to release infection-fighting drugs

    A new material can deliver medications on demand and only when bacteria are present. The advance could be particularly helpful for wound dressings.

  • The robotic swimmer's small body and corkscrew "tail" appears dark against a yellow background.

    Robotic swimmer shows how microorganisms get around

    A self-propelled robotic swimmer gives researchers a chance to see how bacteria and other microorganisms move at a much larger scale.

  • colorful topographic map of moon

    Why the moon’s two faces are so different

    Why the two sides of the moon are so different is one of its most enduring mysteries. Researchers now have an explanation.

  • An artist's interpretation of asteroid 16 Psyche moving through space

    ‘Bizarre’ Psyche asteroid may be less heavy metal, more hard rock

    Scientists believed the asteroid Psyche could be a big ball of pure iron, but it's likely harboring a hidden rocky component, new research shows.

  • orange ball with various numbers on it

    Skyrmions can generate true random numbers

    Skyrmions can be used to generate true random numbers useful in cryptography and probabilistic computing, report researchers.

  • A person stands under a large model of the moon

    Team clarifies puzzle of moon’s magnetic power

    How could our tiny moon have had such a strong magnetic field early in its history? A new study offers some answers.

  • A young man wearing glasses has blue and pink light projected onto his face

    Team pinpoints brain signals tied to OCD symptoms

    Researchers are exploring for brain signals that mark when someone is experiencing OCD symptoms in order to shape future brain stimulation treatments.

  • A rusted bus frame sits in the Atacama desert with a huge white-capped mountain in the distance

    Comet’s intense heat turned sand to glass 12,000 years ago

    Heat from a comet exploding just above the ground in what is now the Atacama Desert in Chile fused sandy soil into patches of glass around 12,000 yeas ago.

  • 9 tiny neurograins sit on a person's finger tip

    Tiny ‘neurograins’ could one day stimulate brain activity

    A new brain-computer interface system that coordinates the activity of hundreds of "neurograin" brain sensors could one day lead to new medical therapies.

  • The implant is a small square of metal with spikes, held in front of a penny for scale

    Interface turns handwriting brain signals into text

    A brain-computer interface allowed a man with paralysis to create computer text at 90 characters per minute just by thinking about handwriting.

  • A metal chip has gold-looking pieces laid on top of it

    ‘Molecular glue’ makes perovskite solar cells tougher

    A "molecular glue" strengthens a key weak point in perovskite solar cells. The advance makes them tougher, more efficient, and more reliable.

  • The crater on Mars is colored to show where water gathered at its bottom

    Ancient crater lake bolsters idea of ice on early Mars

    Glacial runoff appears to have fed an ancient crater lake on Mars, boosting the idea that the red planet had a cold and icy past.
