Rosie Redfield, a microbiologist and one of the first people to criticize the "arsenic life" paper last year, recently announced that she and several colleagues had attempted to replicate the original experiment, without success. The original paper claimed that bacteria found in California's Mono Lake could substitute arsenic for the phosphorous normally found in its DNA. Redfield's team found no evidence that that was happening. However, it's worth noting that Redfield's research hasn't yet been peer-reviewed, and there are still some key questions about methodology—both in the original experiments and in Redfield's follow up—that make it hard to call this an absolute refutation.

In addition to all the game framework and functionality that goes into a build of any size, creators invariably sweat over the most minute details of every weapon, outfit, or other distinctive objects in their game. Even if your game is set […]
We get it. You don’t have to go to the office anymore. That’s no excuse for letting your grooming go positively feral. We’re not saying you need to be GQ cover model-ready every Monday through Friday. But at least put in some effort to keep yourself relatively trimmed, clean, and on point. Even if you […]
With everybody cooped up inside right now, it’s no surprise that many houses are starting to get a little bit…well, funky. Yeah…they smell. With everybody running around and sweating and working and cooking and everything else, odors get trapped inside your home. And don’t even get us started on what happens when litter boxes and […]
