NEW YORK (AP) — A microscopic discovery in a California lake sparked buzz and controversy more than a decade ago when it was first revealed. Scientists said they’d discovered bacteria that used the element arsenic — poisonous to life as we know it — to grow. If true, it expanded the possibilities for where life could exist on Earth — …

Science has retracted a 2010 paper describing a strain of bacteria that purportedly substituted arsenic for phosphorus, an element present in all known life. Science/AAAS Fifteen years after publishing an explosive but long-criticized paper claiming to describe a microbe that could substitute arsenic for phosphate in its chemical makeup, Science is retracting the article, citing “expanded” criteria for retraction.  The …

A fifth planet has been detected within the habitable zone of a neighboring star, where conditions could perhaps support liquid water and potentially life. Located about 35 light-years from Earth, L 98-59 is a cool, dim red dwarf star already known to host a compact system of small, rocky planets. The latest discovery, led by researchers at the Université de Montréal’s …

As the search for life on Mars continues – with the Mars Sample Return program set to return samples of the planet in the early 2030s – one scientist has suggested that we may have already found life on the Red Planet, almost 50 years ago. And then, in what would not be an all-time great first impression, we destroyed …

After 15 years of debate, a study that announced the alleged discovery of an arsenic-eating microbe has been retracted by the journal Science due to contaminated and flawed data. However, the original study authors disagree with the move. The microbe strain, labeled GFAJ-1, was recovered from the salty water of arsenic-rich Mono Lake in California by a research team led …

Psilocybin‘s health benefits could extend beyond the mental realm. A new study in human cells and mice has found the first experimental evidence that the compound can increase longevity and fight signs of aging. Being a psychedelic, psilocybin is usually investigated for its potential as a treatment for depression, anxiety, and other neurological disorders. But there hasn’t been a whole …

It is the ultimate mystery of biology: How did life begin? A team of Harvard scientists has brought us closer to an answer by creating artificial cell-like chemical systems that simulate metabolism, reproduction, and evolution — the essential features of life. The results were published recently in the Proceedings of the National Academy of Sciences. “This is the first time, …
