    Scientists find a naturally occurring molecule that forms a fractal

    The protein assembles itself into a repeating triangle pattern. The fractal seems to be an accident of evolution, scientists say.

  2. Animals

    In a first, these crab spiders appear to collaborate, creating camouflage

    Scientists found a pair of mating crab spiders blending in with a flower. The report may be the first known case of cooperative camouflage in spiders.

  3. Life

    This marine alga is the first known eukaryote to pull nitrogen from air

    An alga’s bacterial symbiote has evolved into an organelle that turns atmospheric nitrogen into ammonia, making the alga unique among eukaryotes.

  4. Space

    How a sugar acid crucial for life could have formed in interstellar clouds

    Computer calculations and lab experiments have revealed a possible mechanism for the creation of glyceric acid, which has been seen in meteorites.

  5. Health & Medicine

    Teens are using an unregulated form of THC. Here’s what we know

    The compound is called delta-8-THC and, like delta-9-THC in marijuana, comes from the cannabis plant and may hurt teens’ brains.

  6. Health & Medicine

    Immune cells’ intense reaction to the coronavirus may lead to pneumonia

    Immune cells that patrol lung tissue may play a role in the progression of a coronavirus infection to pneumonia, lab studies show.

  7. Ecosystems

    Flowers may be big antennas for bees’ electrical signals

    The finding suggests a way for plants to share information about nearby pollinators and communicate when to trigger nectar production.

  8. Health & Medicine

    A protein found in sweat may protect people from Lyme disease

    The protein stopped Borrelia burgdorferi, a bacterium that is transmitted by ticks, from growing in dishes or infecting mice.

  9. Earth

    Polar forests may have just solved a solar storm mystery

    Spikes of carbon-14 in tree rings may be linked to solar flares, but evidence of the havoc-wreaking 1859 Carrington event has proven elusive until now.

  10. Space

    ​​During the awe of totality, scientists studied our planet’s reactions

    Earth’s atmosphere was a big area of focus for scientists studying the total solar eclipse on April 8, 2024.

  11. Environment

    Heat waves cause more illness and death in U.S. cities with fewer trees

    There are usually fewer trees in neighborhoods with higher populations of people of color. Planting trees could save hundreds of lives every year.
