1. small dinosaur

    This ancient dinosaur was no bigger than a hummingbird

    The skull of one of these Mesozoic Era birds — the tiniest yet known — was discovered encased in a chunk of amber originally found in Myanmar.

  2. EEG electrodes on the heads of three different people
    Science & Society

    New electrodes can better capture brain waves of people with natural hair

    Electrodes weren’t designed for people with thick, curly hair. A redesign is needed, says engineer Pulkit Grover.

  3. parazen fish

    This is the first deep-sea fish known to be a mouthbreeder

    Scientists found over 500 eggs attached to the inside of a parazen fish’s mouth.

  4. Animals

    Sea turtles may confuse the smell of ocean plastic with food

    Sea turtles respond to the smell of plastic that’s been in the ocean similarly to food, suggesting the reptiles may end up eating the harmful debris.

  5. sheep

    Brain waves common during sleep also show up in awake sheep

    Sleep spindles, thought to help solidify memories in people, may do similar work during wakefulness if these daytime ripples occur in humans.

  6. Animals

    Bright yellow spots help some orb weaver spiders lure their next meal

    Experiments with cardboard arachnids suggest that orb weaver spiders have evolved yellow colorations on their undersides to attract bees and moths.

  7. Animals

    Glowing frogs and salamanders may be surprisingly common

    A widespread ability to glow in striking greens, yellows and oranges could make amphibians easier to track down in the wild.

  8. Life

    A distant cousin of jellyfish may survive without working mitochondria

    A tiny creature that parasitizes salmon is the first known multicellular eukaryote without a mitochondrial genome, a hallmark of complex life.

  9. Homo erectus skull

    The earliest known hominid interbreeding occurred 700,000 years ago

    The migration of Neandertal-Denisovan ancestors to Eurasia some 700,000 years ago heralded hookups with a resident hominid population.

  10. Life

    How African turquoise killifish press the pause button on aging

    The fish’s embryos can enter a state of suspended growth to survive dry spells. A study shows that state protects them from aging, and hints at how.

  11. Podarcis muralis

    A new lizard parasite is the first known to move from mom to baby

    Nematodes were found living in a lizard’s ovaries and the braincase of her embryos — the first evidence of a reptile parasite that jumps generations.

  12. Olm salamander in cave

    One blind, aquatic salamander may have sat mostly still for seven years

    Olms may live for about century and appear to spend their time moving sparingly.
