A new era of spaceflight could save astronauts time and cut exposure to cosmic radiation as they rocket to Mars--and beyond. Just before the Artemis II crew began its historic slingshot around the moon this past April, NASA announced plans to build Space Reactor-1 Freedom. SR-1, the first-ever nuclear-reactor-powered interplanetary spacecraft, is meant to fly an uncrewed mission to Mars by the end of 2028, arriving in 2029. A successful mission would herald a new era of more efficient, potentially faster spaceflight--saving astronauts time and cutting their exposure to harmful cosmic radiation as they travel to Mars and beyond. "You wake up to that announcement, and it puts a big smile on your face," says Simon Middleburgh, co-director of the Nuclear Futures Institute at Bangor University in Wales. Running a nuclear reactor in space may sound like lunacy, but it's not.

Fuel particles embedded in the dirt aren't changing much, and that's actually a good thing.

A general view shows the current state of the 18.6-mile Chernobyl Exclusion Zone. Established in the aftermath of the 1986 nuclear disaster at the Chernobyl Nuclear Power Plant, the 1,003-square-mile restricted area remains under strict state control. Just over 40 years ago, what began as a routine safety test at the Chernobyl nuclear power plant (or Chornobyl in Ukranian) in Soviet Ukraine spiraled into one of the most recognizable disasters of the 20th century.

Workers wearing protective suits and masks conduct a decommissioning operation at the No. 2 reactor building of the tsunami-crippled Fukushima No.1 nuclear power plant in Fukushima Prefecture, in January. Tokyo - Tokyo Electric Power Company Holdings on Friday started inspections of the interior of the meltdown-stricken No. 2 reactor at the Fukushima No. 1 nuclear power plant, inserting a robotic arm into the containment vessel. The company aims to better understand conditions inside the reactor at the plant in Fukushima Prefecture, as it plans to extract some nuclear fuel debris on a trial basis. The work is expected to take about half a year. According to Tepco, the latest operation involves cutting some rails and cables that could obstruct the robotic arm's entry with high-pressure water jets and collecting 3D data and images from inside the containment vessel.

Plus: A new Amazon data center could become the US's most polluting power plant. Plus: both parties are turning against AI data centers ahead of the midterms. Teaching a computer to use human language requires an inhuman amount of data. An LLM can easily churn through a hundred thousand times more words than a person will experience in the process of mastering their mother tongue. This yawning divide between children and machines is called the data efficiency gap. It raises a tantalizing question for cognitive scientists and a challenge for the architects of AI models: how can children still outperform the most linguistically sophisticated machines ever built?

Is the war entering a new phase? A drone strike close to the Zaporizhzhia Nuclear Power Plant in occupied southeastern Ukraine has killed one nuclear specialist and wounded 17, according to Russian reports. Moscow asserted on Tuesday that the drone was launched by Ukraine. The security of Europe's biggest nuclear plant has provoked significant global concern amid the full-scale war on Ukraine that Russia launched in February 2022. Most of those injured by the strike were employees of the plant, according to a Telegram update by the Russian management of the nuclear facility.

Plus: NATO is building a network to stop Russian attackers in their tracks. I was really looking forward to July 4, and not just because I love a poolside barbecue. This year the American holiday also marked a big symbolic deadline for US nuclear power. Last year the Trump administration set a goal to see three new microreactors achieve criticality, a technical milestone establishing that a reactor can sustain a chain reaction, by the nation's 250th birthday. And just in time, not just three, but four reactors did so. But achieving criticality doesn't mean a reactor is ready to provide electricity for the grid (or at all, for that matter).

For regression on the dataset, we perform leave-one-out cross validation. For the single solvents,865 we leave out one solvent at a time. For the full data, we leave out one solvent ramp at a time. We866 measure the performance of the model on each leave-one-out data split, then take the mean of their867 performance across the dataset. We exclude any experiments involving acetonitrile and acetic acid,868 due to the observed side-reactions.

Plus: Autonomous drones may have killed soldiers for the first time. Imagine tuning in to the opening kickoff of a World Cup match and seeing a player intentionally kick the ball out of bounds. You may question the logic of surrendering possession seconds into a game. If you were Jesse Davis, though, you'd know that this play could be a prime setup to score. Davis is a professor of computer science at KU Leuven in Belgium and head of its Sports Analytics Lab, which has been at the vanguard of a data awakening in soccer. Using AI and data analytics, his team has uncovered hidden tactical patterns and challenged long-held assumptions about how the game should be played.
