>There has long been debate in the scientific community about whether Mars had an ocean in its low-elevation northern hemisphere, Cardenas explained. Using topography data, the research team was able to show definitive evidence of a roughly 3.5-billion-year-old shoreline with substantial sedimentary accumulation, at least 900 meters thick, that covered hundreds of thousands of square kilometers.
Many, many single-purpose rovers can be sent in the place of a human mission with no risk to human life. There is no scientific justification for sending humans on a science mission, it's mostly just adventurism.
>The ex-head of news at Russia's largest internet company has advice for his former colleagues: quit.
>Lev Gershenzon worked at Yandex in various roles for four years, according to his LinkedIn profile. He took to Facebook early Tuesday morning to warn people still working at the company — which is one of the largest search engines in Russia — that it was contributing to the censorship of the country's invasion into Ukraine.
>"The fact that a significant part of the Russian population may believe that there is no war is the basis and driving force of this war," Gershenzon wrote, also tagging six of his former coworkers. "Today, Yandex is a key element in hiding information about war. Every day and hour of such "news" costs human lives. And you, my former colleagues, are also responsible for this."
>Elena Bunina, who is Jewish, is stepping down from her role as CEO of Yandex LLC, 'Russia's Google,' amid the war in Ukraine. Sources confirm she is in Israel and has no intention of returning to Russia
PloS One is not really open access... The vast majority of journals function under a Subscription/Paid open-access model, PloS One just mandates the second option.
I've forked out >$4k for a high-quality journal to make my research open-access. Or I could have paid $0 and it would be behind a paywall.
Some like Nature, publish largely open-access but it can cost >$8k to be published there.
Why should we spend trillions of dollars to put a few people on a distant rock when we could spend that money to help many more people right now, and potentially avert the need for a colonial life raft? It feels self-evident to me.
