Sept. 17, 2023: Our weekly roundup of the latest science in the news, as well as a few fascinating articles to keep you entertained over the weekend.
This week in science news we ponder why an asteroid is behaving in an unusual way, get to grips with a giant gator, and discover the mysterious bamboo that flowers only once a century.
Looking toward space, observations from a California high school teacher and his students suggest that the asteroid Dimorphos, which NASA intentionally hit with a rocket during its DART mission in September 2022, is behaving in unpredicted ways, while the green comet Nishimura passed tantalizingly close to Earth.
In health news, we learnt of a gene variant that may guard against Alzheimer's and Parkinson's, the common decongestant ingredient that doesn't work, and why nicotine vapes are one of the best tools to help people quit smoking.
Picture of the weekIt may look fairly innocuous, like a cigar holder or a comically oversized pen, but it is the contents of this tube, or more specifically where they were taken, that is no laughing matter. On Sept. 8, fragmentary remains of two ancient human relatives, Australopithecus sediba and Homo naledi, were carried aboard a Virgin Galactic flight to the edge of space, leaving a fuming scientific community back on Earth behind them.
