Space hotels have been envisioned since the 1950s, but none have been realized despite multiple ambitious plans and predictions.
Modern scientific societies are increasingly vulnerable due to their dependence on membership fees and journal subscriptions, which are being challenged by the rise of virtual networking and open-access publishing.
The news of the AI's medal win was published by thousands of media outlets and chosen as one of the year's biggest scientific breakthroughs by the journal Science. And this is where the story starts to get complicated. Because the news is a lie.
Computer programs that check mathematical arguments have existed for decades, but translating a human-written proof into the strict programming language of a computer is extremely time-consuming, often taking months or even years.
During the past year, it has become unsafe for our guests to visit the country. We cannot in good conscience ask the new winners, or the international journalists who cover the event, to travel to the USA this year. The move comes amid Donald Trump's sweeping crackdown on immigration, in which he has focused on deporting migrants illegally in the US, as well as holders of student and visitor exchange visas.
Known as ExStra, this is a permanent national funding programme designed to strengthen research at the nation's top universities and make them more competitive internationally. While the ExStra programme allows for up to 15 "Excellent Universities" (Exzellenzuniversitaten), only ten institutions have made the grade for the next round of funding.
Every February 11, the United Nations-designated International Day of Women and Girls in Science reminds us of the myriad obstacles women and girls around the world face within the STEM disciplines and the ways they continue to overcome challenges and stand out in their fields. "Today, women make up less than one third of the world's researchers," says Alexis Abramson, dean of the Columbia Climate School. "Closing this gender gap is not only a matter of fairness but is essential to further the innovation and impact of the work."
His message is clear: our world is built on abundant energy, around 80% of which has come from fossil fuels over the past 50 years. Because supplies are limited, energy consumption will peak in decades - sooner if humans attempt to limit climate change. To keep global warming below 1.5 °C by 2100, the use of fossil fuels must fall by 5-8% each year - a pace that is too fast for low-carbon energy to keep up with.
"We didn't do any LLMs. There is significant interest in that. There are lots of people trying those ideas out, but I think they're still in the exploratory phase," Desai told El Reg. As it turned out, the researchers didn't need them. "We used a simpler model called a variational auto encoder (VAE). This model was established in 2013. It's one of the early generative models," Desai said.
The exponential growth of scientific literature presents an increasingly acute challenge across disciplines. Hundreds of thousands of new chemical reactions are reported annually, yet translating them into actionable experiments becomes an obstacle1,2. Recent applications of large language models (LLMs) have shown promise3,4,5,6, but systems that reliably work for diverse transformations across de novo compounds have remained elusive. Here we introduce MOSAIC (Multiple Optimized Specialists for AI-assisted Chemical Prediction), a computational framework that enables chemists to harness the collective knowledge of millions of reaction protocols.
Iranian researchers are in a difficult situation. Those in Iran face low wages, high inflation, sociopolitical instability, resource mismanagement, oppression by the authorities and long-standing international sanctions. High prices hinder conference attendance, as do difficulties obtaining visas. Unstable Internet connections, frequent power outages and lack of access to scholarly sources jeopardize collaborations. Scholars also have to contend with isolation, and sometimes biases, from the international community. And for those who work abroad, travelling to and from Iran is risky, even with visas and double citizenship.
In fact, Stawicki was on a mission to save the lives of around 1,000 zebrafish ( Danio rerio) in her laboratory. Similarities between lines of hair cells on the fish's flanks and those in the mammalian inner ear enable her to use them as a model to study hearing problems in humans caused by some antibiotics and chemotherapy drugs. A sensor had picked up that the lab's heating system had been knocked out by a power fault.
Science@Cal is proud to present a series of free public science lectures on the third Saturday of every month. These talks are given by renowned UC Berkeley scientists and aimed at general audiences. Talks take place on the UC Berkeley campus at 11 am. Doors open thirty minutes before the talk and seating is on a first-come, first-served basis. Each talk is planned to last an hour, plus time for at least a few questions at the end.
Calling nanoscientists: your field needs you to try to replicate a landmark finding that quantum dots can act as biosensors inside living cells. As part of the first large-scale effort in the physical sciences to tackle the reproducibility crisis, researchers in France and the Netherlands are offering funds and resources in exchange for a few months of work. "We are trying to use
