Scientists have recreated the Universe's first molecule

news.ycombinator.com Unknown 2025-12-11 17:20:51

Immediately after the Big Bang, which occurred around 13.8 billion years ago, the universe was dominated by unimaginably high temperatures and densities. However, after just a few seconds, it had cooled down enough for the first elements to form, primarily hydrogen and helium. These were still completely ionized at this point, as it took almost 380,000 years for the temperature in the universe to drop enough for neutral atoms to form through recombination with free electrons. This paved the way

The Emperor's New Trade Deal – Paul Krugman

news.ycombinator.com Paul Krugman 2025-12-15 03:26:33

On Tuesday Donald Trump went on CNBC to explain why the European Union is facing a tariff of “only” 15 percent. But what he said was simply delusional — and the delusion should be even more concerning than the tariffs. The Europeans, Trump asserted, had agreed to cough up $600 billion, which he described as a “gift,” not a loan. And he emphasized that this is “$600 billion to invest in anything I want. Anything. I can do anything I want with it.” So Trump apparently believes that the European

As Poynter celebrates its 50th anniversary, we examine how the media landscape has evolved and what it means for the next era of news. The decline of newspaper print classifieds and the ripple effects that gutted newsrooms began, by many accounts, in 1995. That’s when Craig Newmark invented Craigslist, the homely but oh-so

Our Brains Contain Lithium—and Its Loss Might Help Drive Alzheimer’s, Study Finds

Alzheimer’s disease is one of the cruelest conditions a person can develop. And even with recent advances, there’s only so much that can be done once its symptoms emerge. Research out this week might highlight a critical and previously missed factor driving the disease, one that could even lead to new treatments.

Because photography is important to me, I've always picked the iPhone Pro with its telephoto camera over the regular iPhone models. But each year I'm pulled in two directions: Pick the standard-sized iPhone Pro or the larger iPhone Pro Max? Some years the latter includes photo features not found on the regular iPhone Pro, such as the 5x zoom that was exclusive to the iPhone 15 Pro Max. And as we approach the reveal of the next iPhone 17 lineup, I'm once again waffling between sizes. And based on

Ryan Haines / Android Authority Motorola Razr (2025) I absolutely love flip phones, mainly because I am a fan of smaller devices.
