New AI benchmarks could help developers reduce bias in AI models, potentially making them fairer and less likely to cause harm. The research, from a team based at Stanford, was posted to the arXiv preprint server in early February. The researchers were inspired to look into the problem of bias after witnessing clumsy missteps in...

US electricity consumption is rising faster than it has in decades, thanks in part to the boom in data center development, the resurgence in manufacturing, and the increasing popularity of electric vehicles. Accommodating that growth will require building wind turbines, solar farms, and other power plants faster than we ever have before-and expanding the network...

Facing defeat in chess, the latest generation of AI reasoning models sometimes cheat without being instructed to do so. The finding suggests that the next wave of AI models could be more likely to seek out deceptive ways of doing whatever they've been asked to do. And worst of all? There's no simple way to...

Since the emergence of enterprise-grade generative AI, organizations have tapped into the rich capabilities of foundational models, developed by the likes of OpenAI, Google DeepMind, Mistral, and others. Over time, however, businesses often found these models limiting since they were trained on vast troves of public data. Enter customization-the practice of adapting large language models...

They're small, fluffy, and kind of cute, but these mice represent a milestone in de-extinction efforts, according to their creators. The animals have undergone a series of genetic tweaks that give them features similar to those of woolly mammoths-and their creation may bring scientists a step closer to resurrecting the giant animals that roamed the...

Technological advances continue to move at breakneck speeds. While companies struggle through their digital transformation journeys, even more new technologies emerge, with promises of opportunity, cost savings-and added complexity. Many companies have yet to fully adopt AI and ML technologies, let alone figure out how newer technologies like generative AI might fit into their programs....

Tourists to Odense, Denmark, come for the city's rich history and culture: It's where King Canute, Denmark's last Viking king, was murdered during the 11th century, and the renowned fairy tale writer Hans Christian Andersen was born there some 700 years later. But today, Odense (with a population just over 210,000) is also home to...

The tiny beads added to some cleansers and cosmetics are one source of the long-lasting microplastics that threaten the environment. But MIT researchers have found a way to address the problem at its source: replacing them with polymers that break down into harmless sugars and amino acids. Particles of this polymer could also be used...

Wearable devices like smart watches and fitness trackers help us measure and learn from physical functions such as heart rates and sleep stages. Now MIT researchers have developed a tiny equivalent for individual brain cells. These soft, battery-free wireless devices, actuated with light, are designed to wrap around different parts of neurons, such as axons...

For all the talk about artificial intelligence upending the world, its economic effects remain uncertain. But Institute Professor and 2024 Nobel winner Daron Acemoglu has some insights. Despite some predictions that AI will double US GDP growth, Acemoglu expects it to increase GDP by 1.1% to 1.6% over the next 10 years, with a roughly...

Although it is less abundant than carbon dioxide, methane gas contributes disproportionately to global warming. Its molecular structure of single carbon atoms bound to four hydrogen atoms makes it a potentially useful building block for products that could keep this carbon out of the atmosphere, but it's hard to get it to react with other...

The cerebral cortex contains regions devoted to processing different types of sensory information, including visual and auditory input. Now researchers led by Robert Desimone, director of MIT's McGovern Institute for Brain Research, and colleagues have developed the most comprehensive picture yet of what all these regions do. They achieved this by analyzing data collected as...

Metabolic imaging is a valuable noninvasive method for studying living cells with laser light, but it's been constrained by the way light scatters when it shines into tissue, limiting the resolution and depth of penetration. MIT researchers have developed a new technique that more than doubles the usual depth limit while boosting imaging speeds, yielding...
