Automated method helps researchers quantify uncertainty in their predictions

Pollsters trying to predict presidential election results and physicists searching for distant exoplanets have at least one thing in common: They often use a tried-and-true scientific technique called Bayesian inference. Bayesian inference allows these scientists to effectively estimate some unknown parameter — like the winner of an election — from data such as poll results. […]

MIT researchers remotely map crops, field by field

Crop maps help scientists and policymakers track global food supplies and estimate how they might shift with climate change and growing populations. But getting accurate maps of the types of crops that are grown from farm to farm often requires on-the-ground surveys that only a handful of countries have the resources to maintain. Now, MIT […]

Researchers release open-source space debris model

MIT’s Astrodynamics, Space Robotics, and Controls Laboratory (ARCLab) announced the public beta release of the MIT Orbital Capacity Assessment Tool (MOCAT) during the 2023 Organization for Economic Cooperation and Development (OECD) Space Forum Workshop on Dec. 14. MOCAT enables users to model the long-term future space environment to understand growth in space debris and assess […]

Co-creating climate futures with real-time data and spatial storytelling

Virtual story worlds and game engines aren’t just for video games anymore. They are now tools for scientists and storytellers to digitally twin existing physical spaces and then turn them into vessels to dream up speculative climate stories and build collective designs of the future. That’s the theory and practice behind the MIT WORLDING initiative. […]

Smart irrigation technology covers “more crop per drop”

In agriculture today, robots and drones can monitor fields, temperature and moisture sensors can be automated to meet crop needs, and a host of other systems and devices make farms more efficient, resource-conscious, and profitable. The use of precision agriculture, as these technologies are collectively known, offers significant advantages. However, because the technology can be […]

To excel at engineering design, generative AI must learn to innovate, study finds

ChatGPT and other deep generative models are proving to be uncanny mimics. These AI supermodels can churn out poems, finish symphonies, and create new videos and images by automatically learning from millions of examples of previous works. These enormously powerful and versatile tools excel at generating new content that resembles everything they’ve seen before. But […]

“Pangea” study aims to modernize national test and training infrastructure

Whenever the United States develops a new system — say, a plane — this system needs to be tested and validated to ensure all of its components are working as intended. That’s where the U.S. national test and training infrastructure comes into play. Across the country are many different ranges focused on assessing the systems […]

Teachers embrace hands-on learning in Materials Genome Camp

Amid the brick furnaces of MIT’s forge and foundry, Mike Tarkanian poured liquid metal into a mold until it filled, then he emptied the rest into a trough. To demonstrate how quickly it solidified in the ambient temperature of the room, the senior lecturer in the MIT Department of Materials Science and Engineering (DMSE) kicked […]
