Nvidia researchers unveiled a new technique that drastically reduces the memory costs associated with large language model (LLM) reasoning, while the Department of Homeland Security (DHS) announced that immigration agents may have lied about a recent shooting. Meanwhile, a study suggests moderate caffeine intake could slow brain aging, and Wikipedia is experiencing a resurgence despite facing challenges from AI. These developments, along with a look at potential positive impacts of the Trump administration on science, highlight a range of news from February 12-13, 2026.
Nvidia's new technique, dynamic memory sparsification (DMS), can cut the memory costs of LLM reasoning by up to eight times, according to VentureBeat. This method compresses the key value (KV) cache, which LLMs use to store temporary memory while processing prompts. Experiments showed that DMS allows LLMs to "think" longer and explore more solutions without increasing memory usage, according to the source.
In other news, the Department of Homeland Security stated that two federal immigration agents involved in a shooting in Minneapolis last month appear to have provided false statements about the incident. A spokesperson for DHS said that a joint review by ICE and the Department of Justice, which included video evidence, revealed that the agents' sworn testimony contained "untruthful statements," according to NPR News. The agents have been placed on administrative leave.
A study highlighted in Nature News suggests that moderate caffeine intake might reduce the risk of dementia. The study, which analyzed data from 130,000 people, found a link between coffee consumption and slower brain aging.
Additionally, Wikipedia is experiencing a renaissance in the age of AI, according to Vox. The online encyclopedia, a staple for many students, is facing questions about its future as AI bots train using its content. "After allowing AI bots to train using their content, there are questions about the future of Wikipedia's human-powered identity," stated Kyndall Cunningham, a culture writer for Vox.
Finally, Vox also reported that the Trump administration might actually do something positive for science. While the administration's scientific agenda has been widely criticized, there are other factors at play, according to Marina Bolotnikova, a senior reporter for Vox's Future Perfect section.
