Musk is, in fact, deadly serious about colonizing the Red Planet. Part of his motivation is the idea of having a "back-up" planet in case some future catastrophe renders the Earth uninhabitable. Musk has suggested that a million people may be calling Mars home by 2050 -- and he's hardly alone in his enthusiasm. Venture capitalist Marc Andreessen believes the world can easily support 50 billion people, and more than that once we settle other planets. And Jeff Bezos has spoken of exploiting the resources of the moon and the asteroids to build giant space stations. "I would love to see a trillion humans living in the solar system," he has said. Not so fast, cautions science journalist Adam Becker.

Health and Human Services Secretary Robert F. Kennedy Jr. conducts a news conference to discuss the Centers for Disease Control and Prevention's latest Autism and Developmental Disabilities Monitoring Network survey.Tom Williams/CQ Roll Call/AP While his anti-vaccine allies swooned and scientists cringed, HHS Secretary Robert F. Kennedy Jr. used his first-ever press conference this week, in response to new data showing an apparent increase in the number of autistic kids, to promote a variety of debunked, half-true, and deeply ableist ideas about autism. He painted the condition as a terrifying "disease" that "destroys," as he put it, children and their families. Kennedy made it clear he planned to use his powerful role as the person in charge of a massive federal agency devoted to protecting public health to promote the idea that autism is caused by "environmental factors," a still-speculative thesis that's clearly a short walk towards advancing his real aim: blaming vaccines. Kennedy has spent the last 20 years promoting anti-vaccine rhetoric, falsely and repeatedly claiming that vaccines are linked to autism. Yet as the press conference made clear, Kennedy knows startlingly little about autism.

This story was originally published by WIRED and is reproduced here as part of the Climate Desk collaboration. Last Tuesday, President Donald Trump held a press conference to announce the signing of executive orders intended to shape American energy policy in favor of one particular source: coal, the most carbon-intense fossil fuel. "I call it beautiful, clean coal," President Trump said while flanked by a crowd of miners at the White House. "I tell my people never use the word coal unless you put'beautiful, clean' before it." Trump has talked about saving coal, and coal jobs, for as long as he's been in politics.

"When not wasting money on bureaucracy," he wrote, "The Department of Education has been funding anti-Americanism, gender nonsense and anti-meritocratic racism." By the end of the month, the department had been stripped to the bone, dismantled by Donald Trump and Musk's DOGE. And on Thursday, Education Secretary Linda McMahon, who has said her agency's "final mission" would be to send education programs "back to the states," was on hand as the president signed an executive order to begin eliminating what remained of the department. The companies' founders share an admiration for Musk and desire to help their students replicate his success. At the same time that federal support for public education is imperiled, two private online education programs whose seeds were planted with Musk and SpaceX are getting a second wind.

President Joe Biden signs a document with his very own hands.Oliver Contreras/White House/Zuma President Donald Trump has a new hobbyhorse: That his predecessor, President Joe Biden, didn't legally grant pardons to people Trump wants to harass because the pardons were signed with an autopen, a device for replicating a signature, rather than by hand. Trump has identified some signature requirement as the one rule presidents must obey. "The'Pardons' that Sleepy Joe Biden gave to the Unselect Committee of Political Thugs, and many others, are hereby declared VOID, VACANT, AND OF NO FURTHER FORCE OR EFFECT, because of the fact that they were done by Autopen," he ranted on Truth Social just after midnight on Monday. "In other words, Joe Biden did not sign them but, more importantly, he did not know anything about them!" Trump and his MAGA allies have embraced a lawless approach to the presidency. Trump's executive orders, actions, and legal filings all point to an understanding of the president as far more powerful than previously understood, with king-like powers over the entire executive branch.

Last week, standing in front of President Donald Trump's first Cabinet meeting, Elon Musk, the unelected billionaire running a blitzkrieg against the US government, acknowledged that he had made a mistake--that in going after the US Agency for International Development, the foreign assistance program that he has all but destroyed, he accidentally ended the Ebola prevention project it ran overseas. Musk claimed the error was quickly fixed and there was no interruption in service. But former and current USAID staff quickly told the Washington Post that Musk was wrong--the Ebola response remained sharply curtailed. And, as the Bulwark reported, Nicholas Enrich, the acting assistant administrator for global health at USAID, who was placed on administrative leave Sunday, had drafted an unfinished memo that predicted the demolition of USAID would lead to more than 28,000 cases of Ebola and related diseases, as well as a 28 to 32 percent increase in tuberculosis globally, up to 18 million cases of malaria (with up to 166,000 deaths annually), and an additional 200,000 cases of paralytic polio a year. Musk's assertion that his slash-and-burn assault on USAID had no negative impact on combating Ebola was disinformation. He was hiding the truth on a critical global health issue.

The White House today announced the name of the acting administrator of the Department of Government Efficiency: Amy Gleason, the US government's problem solver in the early days of the data-starved response to the Covid pandemic and a seasoned worker in the health space. The White House named Gleason after it argued in court that Elon Musk is not really the head of DOGE, and faced pressure from a federal judge to say who is. How long Gleason has been the acting administrator, and if Musk was an unofficial one before today's announcement, is unclear. This is Gleason's second time working in US Digital Services, now turned DOGE. In her first tour, which started in 2018 and carried through the frenzied and chaotic pandemic response, she pushed the bounds of existing bureaucracy to meet the crisis' demand.

Artificial intelligence is driving up demand for electricity--the only question is how much, and what provides the power. Over the next three years, the Lawrence Berkeley National Laboratory estimates, AI's thirst for power will double or triple. Last month, OpenAI unveiled its Stargate Project, a plan to invest 500 billion in the infrastructure for artificial intelligence over the next four years that includes adding 25 gigawatts of new electricity capacity. Right now, the most likely source of electricity to power those data centers is gas.

Axios reported on Friday that Apple CEO Tim Cook will donate 1 million to Donald Trump's inauguration, the latest tech company figure to do so. These donations--which aren't covered by campaign finance law and can be unlimited--signal a clear willingness to work with the Trump administration and a desire to curry favor with the once and future president. The tech sector is particularly eager to suck up. In December, Meta and Amazon donated 1 million to the inauguration committee, and OpenAI's Sam Altman said he planned to do the same. Uber and its CEO Dara Khosrowshahi have both donated 1 million apiece (even as the company's chief legal officer Tony West is vice president Kamala Harris' brother-in-law).

So much of this year felt like a fever dream: The attempted assassination of Donald Trump. Which is why, this year, I'm leaning into my nerdish tendencies and rounding up some good, interesting, or inspiring news stories from the science world--promising discoveries, exciting new data, historic events, and unsung heroes. In the hope of providing relief from the hell that has been 2024, here's a non-comprehensive list of the year's coolest science stories, both big and small: Wildlife filmmaker Carlos Gauna and University of California, Riverside, PhD student Phillip Sternes spotted what appears to be a baby great white shark off the coast of California last year. In January, the team published the photos in the journal Environmental Biology of Fishes. "Where white sharks give birth is one of the holy grails of shark science. No one has ever been able to pinpoint where they are born, nor has anyone seen a newborn baby shark alive," Gauna said in a UC Riverside press release.
