September 2022—Anna Louie Sussman Like me, my eggs were flying economy class. They were ensconced in a cryogenic storage flask packed into a metal suitcase next to Paolo, the courier overseeing their passage from a fertility clinic in Bologna, Italy, to the clinic in Madrid, Spain, where I would be undergoing in vitro fertilization. The shipping of gametes and embryos around the world is a growing part of a booming global fertility sector. As people have children later in life, the need for fertility treatment increases each year. After paying for storage costs for six and four years, respectively, at…
A tale of two coal declines The power plant, scheduled to shut down at midnight on September 30, is called Ratcliffe-on-Soar, and it’s the last bastion of coal in the UK, where the fuel has a rich history. The country relied on coal for over 100 years, and until 1990, it made up the lion’s share of electricity generated there. Since then, the UK has seen two major waves of cutting down coal. The first came in the 1990s, when coal went from around 65% of electricity supply to roughly 35%, and there was a series of mine closures across…
California Gov. Gavin Newsom on Sunday vetoed a landmark bill aimed at establishing first-in-the-nation safety measures for large artificial intelligence models.The decision is a major blow to efforts attempting to rein in the homegrown industry that is rapidly evolving with little oversight. The bill would have established some of the first regulations on large-scale AI models in the nation and paved the way for AI safety regulations across the country, supporters said.Earlier this month, the Democratic governor told an audience at Dreamforce, an annual conference hosted by software giant Salesforce, that California must lead in regulating AI in the face…
In Finland, classes in recognizing fake news, disinformation – CBS News Watch CBS News Being able to identify hoaxes, avoid scams, and debunk propaganda is a civic skill required in today’s information society. That’s why the curriculum of students in Finland includes media literacy lessons, aimed at safeguarding a precious resource: the truth. Correspondent Chris Livesay reports.

SpaceX launches capsule that will give Starliner crew a ride home – CBS News Watch CBS News A SpaceX Falcon 9 rocket blasted off from Cape Canaveral, Florida, on Saturday with a NASA astronaut and a Russian cosmonaut aboard a Crew Dragon capsule that normally carries four. That is because the Crew Dragon’s two empty seats will be used to give two Boeing Starliner astronauts a ride back to Earth next February. Butch Wilmore and Suni Williams were part of Boeing’s first crewed test flight of its Starliner, and though it got them to the International Space Station back in…
“As long as we effectively subsidize fossil fuels by allowing them to use the atmosphere as a waste dump, we are not allowing clean energy to compete on a level playing field,” Zeke Hausfather, a climate scientist at the independent research organization Berkeley Earth, wrote on X in a response to Altman’s post. “We need policy changes, not just tech breakthroughs, to meet our climate goals.” That’s not to say there aren’t big technical problems we still need to solve. Just look at the continuing struggles to develop clean, cost-competitive ways of fertilizing crops or flying planes. But the fundamental…
Long-distance space travel can wreak havoc on human health. There’s radiation and microgravity to contend with, as well as the psychological toll of isolation and confinement. Research on identical twin astronauts has also revealed a slew of genetic changes that happen when a person spends a year in space.That’s why some bioethicists are exploring the idea of radical treatments for future astronauts. Once we’ve figured out all the health impacts of space travel, they argue, we should edit the genomes of astronauts ahead of launch to offer them the best protection. Some have even suggested this might result in the…
Whether people are going into space as tourists, employees, scientists, or research subjects, figuring out how to send them safely is vitally important. After all, space tourism is nothing like regular tourism. “You’re putting [people] in a situation the human body was never designed to be in,” says Wolpe. Now read the rest of The Checkup Read more from MIT Technology Review’s archive Scientists can test-drive space missions in extreme and remote environments here on Earth. “Analogue astronaut facilities,” which have been set up in deserts and in the Antarctic, simulate the isolating experience of real space travel, Sarah Scoles…
Super Micro Computer’s stock price fell sharply on Thursday after the Wall Street Journal reported that the Department of Justice is investigating the server maker.Shares of the company, which sports a market capitalization of nearly $24 billion and which has been boosted by investor interest in artificial intelligence, sank $54, or roughly 12%, in afternoon trade.The Journal cited people familiar with the matter in reporting that the Justice Department has opened a probe into Super Micro, with the investigation in its initial phases. The agency’s investigation followed a critical report in August about Super Micro by Hindenburg Research, an investment firm…
In the decade-long fight to control CRISPR, the super-tool for modifying DNA, it’s been common for lawyers to try to overturn patents held by competitors. But now, in a surprise twist, the team that earned the Nobel Prize in chemistry for developing CRISPR is asking to cancel two of their own seminal patents, MIT Technology Review has learned. The request to withdraw the pair of European patents, by lawyers for Emmanuelle Charpentier and Jennifer Doudna, comes after a damaging August opinion from a European technical appeals board, which ruled that the duo’s earliest patent filing didn’t explain CRISPR well enough…
That nuclear power plant is typically associated with a very specific event. One of its reactors, Unit 2, suffered a partial meltdown in 1979 in what remains the most significant nuclear accident in US history. It has been shuttered ever since. But the site, in Pennsylvania, is also home to another reactor—Unit 1, which consistently and safely generated electricity for decades until it was shut down in 2019. The site’s owner announced last week that it has plans to reopen the plant and signed a deal with Microsoft. The company will purchase the plant’s entire electric generating capacity over the…
Participating developers will make two different models. The first, for those with intermediate skill sets, is one that identifies hateful images; the second, considered an advanced challenge, is a model that attempts to fool the first one. “That actually mimics how it works in the real world,” says Chowdhury. “The do-gooders make one approach, and then the bad guys make an approach.” The goal is to engage machine-learning researchers on the topic of mitigating extremism, which may lead to the creation of new models that can effectively screen for hateful images. A core challenge of the project is that hate-based…
Michael Skelly hasn’t learned to take no for an answer. For much of the last 15 years, the energy entrepreneur has worked to develop long-haul transmission lines to carry wind power across the Great Plains, Midwest, and Southwest. But so far, he has little to show for the effort. Skelly has long argued that building such lines and linking together the nation’s grids would accelerate the shift from coal- and natural-gas-fueled power plants to the renewables needed to cut the pollution driving climate change. But his previous business shut down in 2019, after halting two of its projects and selling…
Meta’s artificial intelligence-powered chatbot spoke to CEO Mark Zuckerberg in a voice familiar to fans of American actress, comedian and rapper Awkwafina in a demo of the enhanced AI tool on Wednesday. That’s because Meta AI, the company’s virtual assistant, now reads aloud its responses to user queries, and can do so in the voice of a number of celebrities, the technology company announced at its Connect conference. The chatbot, which Meta says has roughly 400 million users, lets you choose the voice you hear.Now those voices include Awkwafina, Kristin Bell, John Cena, Dame Judi Dench and Keegan-Michael Key, the company…
Ai2 achieved this by getting human annotators to describe the images in the model’s training data set in excruciating detail over multiple pages of text. They asked the annotators to talk about what they saw instead of typing it. Then they used AI techniques to convert their speech into data, which made the training process much quicker while reducing the computing power required. These techniques could prove really useful if we want to meaningfully govern the data that we use for AI development, says Yacine Jernite, who is the machine learning and society lead at Hugging Face, and was not…
