    Google figures out how to watermark AI-designed proteins (opens the original)

    Excerpt · English

    Read excerpt

    AI-based tools seem to be causing security threats on a nearly daily basis, in part because we’ve been slow to recognize potential threats. One area where we seem to be ahead of the game, however, is in biosecurity. As with most things biological, utility goes hand in hand with threats. We’ve developed increasingly sophisticated tools for designing proteins and seen some major successes, such as AI-designed enzymes that can digest plastics or block venom proteins. But these same tools could be u

    Is solar's growth finally slowing in the US? (opens the original)

    Excerpt · English

    Read excerpt

    Normally, we try to update you quarterly on what’s going on with the US electric grid since it provides a nice view of developing trends and smooths out some month-to-month randomness. Unfortunately, I was out of the office when last month’s data was released, so this will be a seven-month update on 2026 trends. The top line item is that energy use is continuing to rise, albeit not as quickly as headlines about data centers might lead people to believe. Beyond data centers, there’s a growing ele

    Trump's forced coal plant extensions thrown out by judge (opens the original)

    Excerpt · Critical tone · English

    Read excerpt

    The use of coal to generate electricity on the US grid has been plunging for nearly two decades, and the first Trump administration was unable to affect the trend. So his second administration has attempted more aggressive interventions to prop up coal use. One of its most direct means of doing so is to order coal plants that were scheduled to close to remain open, even if there is no need for them. The administration’s justification for these orders is a statute that allows the Department of En

    Google's AI genome system evaluates every possible one-base change (opens the original)

    Excerpt · Neutral tone · English

    Read excerpt

    On Tuesday, Google announced AlphaGenome Atlas, a resource that attempts to predict the consequences of every possible single-base variant in the human genome. The human genome is about 3 billion bases long, so trying the other three DNA bases that don’t appear in our reference genome means sending a total of 9 billion bases through AlphaGenome software. AlphaGenome is designed to identify potential functions of non-coding DNA, which does not encode proteins but makes up the vast majority of the

    NIH to use part of its budget to pay for Department of Defense research (opens the original)

    Excerpt · English

    Read excerpt

    Late last week, word started leaking that the National Institutes of Health (NIH) had reached an agreement with the Department of Defense that would see part of the NIH’s budget used to fund research at the Department of Defense. So, on the Friday just prior to a US holiday weekend, the Department of Defense released a copy of the agreement and confirmed that it had been signed roughly a month earlier. The move is striking for a number of reasons, ranging from the existing budget disparities bet
