Brewing byproduct may be a key sustainable secret ingredient. Breakthroughs, discoveries, and DIY tips sent every weekday. Brewing beer relies on a very simple living thing-brewer's yeast. The microorganisms thrive on mashed grains, converting sugars into both alcohol and carbon dioxide along the way. But there's not much use for yeast after the pints are poured .

The Download: Trump's impact on science, and meet our climate and energy honorees How Trump's policies are affecting early-career scientists--in their own words Every year MIT Technology Review celebrates accomplished young scientists, entrepreneurs, and inventors from around the world in our Innovators Under 35 list. We've just published the 2025 edition . This year, though, the context is different: The US scientific community is under attack. Since Donald Trump took office in January, his administration has fired top government scientists, targeted universities and academia, and made substantial funding cuts to the country's science and technology infrastructure. We asked our six most recent cohorts about both positive and negative impacts of the administration's new policies. Their responses provide a glimpse into the complexities of building labs, companies, and careers in today's political climate.

A legal battle is brewing, as two companies are suing to overturn the two-year ban. Last week, a legal battle over lab-grown meat kicked off in Texas. On September 1, a two-year ban on the technology went into effect across the state; the following day, two companies filed a lawsuit against state officials. The two companies, Wildtype Foods and Upside Foods, are part of a growing industry that aims to bring new types of food to people's plates. These products, often called cultivated meat by the industry, take live animal cells and grow them in the lab to make food products without the need to slaughter animals. Here's what we know about lab-grown meat and climate change Cultivated meat is coming to the US.

Ultra-realistic images created by AI show what your dinner could look like in 30 years' time as we're forced to eat'sustainability'. Experts have used AI tool Midjourney to bring to life the menu of 2054, which features bizarre dishes such as cricket salad and lab-grown steaks. There's even green spaghetti and'meat' balls made out of an aquatic plant, which look straight from the kitchen of another galaxy. These unusual creations could replace family favourite dishes such as the traditional Sunday roast or fish and chips, the scientists believe. They have lower carbon footprints than such classics, which means they could help in the battle against climate change – but would you eat them?

To us it shows how the spirit of innovation can pull ahead of reality, sometimes with unpleasant consequences. It was a phenomenon we saw time and again this year, like when GM's Cruise division put robotaxis into circulation before they were ready. Was the company in such a hurry because it's been losing $2 billion a year? Others find convoluted ways to keep hopes alive, like a company that is showing off its industrial equipment but is quietly still using bespoke methods to craft its lab-grown meat. The worst cringe, though, is when true believers can't see the looming disaster, but we do.

The news: A new system for noise-canceling headphones lets users opt back in to certain sounds they'd like to hear, such as babies crying, birds tweeting, or alarms ringing. How it works: The system, which is still in prototype, connects off-the-shelf headphones to a smartphone app. The microphones embedded in these headphones, which are used to cancel out noise, also detect the sounds in the world around the wearer. These sounds are then played back to a neural network, which has been trained to recognize 20 everyday noises; then certain sounds are boosted or suppressed in real time, depending on the user's preferences. Why it matters: Researchers have long tried to solve the "cocktail party problem"--that is, to get a computer to focus on a single voice in a crowded room, as humans are able to do.

Soon, the menu in your favorite burger joint could include not only options made with meat, mushrooms, and black beans but also patties packed with lab-grown animal cells. Not only did the US just approve the sale of cultivated meat for the first time, but the industry is in the process of raising billions of dollars to bring its products to restaurants and grocery stores. In theory, that should be a big win for the climate--greenhouse-gas emissions from the animals we eat account for nearly 15% of the global total. But whether cultivated meat really is better for the environment is still not entirely clear. Two weeks ago, Senate majority leader Chuck Schumer announced his grand strategy for AI policymaking at a speech in Washington, DC, ushering in what might be a new era for US tech policy.

The news: Disinformation generated by AI may be more convincing than disinformation written by humans, according to a new study. It found that people were 3% less likely to spot false tweets that had been generated by AI than real-life examples collected from Twitter. But the way in which GPT-3 orders information could have something to do with it, as AI-generated text tends to be more structured and condensed in comparison to how humans write. Why it matters: AI models can generate incorrect text that appears convincing, which could be used to generate false narratives quickly and cheaply for conspiracy theorists and disinformation campaigns. In theory, this could be spread further and faster than online disinformation networks manned by humans.

Margaret Mitchell had been working at Google for two years before she realized she needed a break. Only after she spoke with a therapist did she understand the problem: she was burnt out. She ended up taking medical leave because of stress. Mitchell, who now works as an AI researcher and chief ethics scientist at the AI startup Hugging Face, is far from alone in her experience. Burnout is becoming increasingly common in responsible-AI teams, who are unlikely to receive the same levels of support as colleagues who specialize in content moderation, although the work can be just as psychologically draining.
