  • Ferns Get It On After 60 Million Years Apart


    An unassuming little fern has left scientists scratching their heads at the feat of reproductive hijinks it apparently represents. The fern, xCystocarpium roskamianum (the prefix ‘x’ indicates it is a hybrid), collected in the French Pyrenees, appeared to be a blend of two ferns they know well. Although this fern is infertile as many hybrids [...]

    Tiny Cell Grows Giant Death Spike and Lives to Grow Another


    Let’s say you’re a small cell engaged in heavy manufacturing. Like most animal cells, you are coated only in a thin membrane made a double layer of fluid fat-like molecules. The thing you make is a giant, pointy glass rod twice your size. Would you expect to survive this process? Well, if you’re a cell [...]

    Two-Billion-Year-Old Fossils Reveal Strange and Puzzling Forms


    To a human, two billion years is an unfathomable interval. But that, a team of European, Gabonese, and American scientists now say, is how long ago a recently discovered hoard of fossils suggests Earth’s first big life evolved — large enough to see with the naked eye, and in a spectrum of forms that tease [...]

    Deepest Fish Features Angel Wings, Tentacles and Amazing Ability to Perform Under Pressure


    There comes a depth at which even fish struggle to survive the titanic pressure. But that depth is only found at the few places on Earth that lie below 27,600 feet of water, where the weight of the water warps piscine proteins and crushes cells. Such a place is the Mariana Trench, which plunges to [...]
