- Australian scientists have reportedly discovered the oldest living organism in ~100,000 year-old seagrass growing in large patches in the Mediterranean. The seagrass, known as Posidonia oceanica, reproduces asexually, branching continuously — essentially cloning itself — and is thus able to maintain one protracted lifespan as opposed to sexually reproducing organisms which begin a new lifespan with each offspring. However, the scientists are worried about the long-term stability of the seagrass due to (guess what) global warming.
- Russian scientists, after a decade of extremely difficult drilling, have tapped a prehistoric lake submerged 2 miles below the surface of Antarctica. The lake, which has not been exposed to light or air for more than 15 million years, is of particular interest for its similarity to suspected water sources on Jupiter’s moons, and therefore may offer insight to the viability of microbial extraterrestrial life if any are to be found.
- An international team of scientists have recreated the mating call of a 165-million-year-old Katydid using very, very well-preserved fossils.
- A recent article from researchers at Yale proposes the next supercontinent, Amasia, will form around the Arctic Circle as opposed to one or another postion along the Equator, as prior simulations have hypothesized. The supercontinent won’t form for at least another 100 million years, during which time it’s predicted the human race will cease to exist so we’ll never really know will we.
