Ames's contributions to Artemis II‎

NASA successfully sent four astronauts around the moon for the first time in more than 50 years, setting the stage for future lunar landing missions. As the agency continues to push the bounds of space exploration, NASA's Ames Research Center in California's Silicon Valley provided essential support in preparing for the mission.

Astronomers find an exo-Jupiter, and it seems to have clouds‎

A team of astronomers led by Elisabeth Matthews at the Max Planck Institute for Astronomy (MPIA) has made a discovery that highlights the limits of most current models of exoplanet atmospheres: water-ice clouds on a distant Jupiter-like exoplanet called Epsilon Indi Ab.

Discovering a favorite pit stop and communication hub for cloud forest canopy dwellers‎

In his time spent in the lush canopies of Costa Rica's cloud forest, UConn Department of Ecology and Evolutionary Biology Ph.D. student Jeremy Quirós-Navarro has worked as an arborist, helped place camera traps, collected plant samples, and trained others how to climb, all while observing the amazing wildlife of this towering and unstudied ecosystem. Over time, Quirós-Navarro noticed an interesting pattern in the habits of the canopy animals involving their choice of locations to take care of their latrine needs. These findings are published in Ecology and Evolution.

Researchers find children are good at making parents more eco-friendly‎

Getting people to change their behavior is a challenging task. From the Stanford Marshmallow Experiment to the Piano Stair Experiment, scientists have been trying to understand what motivates people to alter their actions for decades. Those hurdles are especially pronounced when it comes to climate change, where overcoming the intention-action gap is a major challenge. Just because someone is concerned about climate change doesn't mean they will change what they do on a daily basis.

Engineers develop a new system to track material design processes‎

Discovering and characterizing new materials is important for unlocking advances in fields like clean energy, advanced manufacturing, and improved infrastructure. Researchers use machine learning and other computational tools to help them, but the trial-and-error nature of the process creates specific challenges.

It wasn't just water: The hidden force inside Japan's 2011 tsunami changed everything‎

Mud-rich coastlines could face a greater tsunami risk, at least that may have been the case for the 2011 Tōhoku-oki tsunami that killed more than 19,000 people and led to the Fukushima Daiichi nuclear disaster. According to a new study published in the Journal of the Geological Society, mud may have made the catastrophic ocean waves more destructive than they might otherwise have been.

Both bonobos and dolphins form unexpected alliances with 'outsiders'‎

Cooperation is a pillar of human society, promoting an exchange of skills and knowledge between different individuals and social groups. Humans typically do not only cooperate with their own family, friends and members of their community, but also with others who are unrelated to them and are outside of their social circle.

Researchers have spent decades breeding better potatoes for chips, and their work isn't done‎

There's a surprising amount of science in a bag of potato chips. Researchers have spent decades developing potatoes for chip makers that can grow in all kinds of climates, avoid diseases and pests, sit in storage for months and still deliver a satisfying crunch. They've also kept an eye on consumer trends; a shift to snack-size portions has increased the demand for smaller chipping potatoes, for example.

Geoengineering could protect Amazon rainforest from climate change‎

Geoengineering could protect the Amazon rainforest from climate change, new research shows. Stratospheric aerosol injection (SAI) aims to artificially cool Earth by increasing the reflection of incoming solar radiation, thereby offsetting warming caused by anthropogenic greenhouse gases. SAI is designed to mimic explosive volcanic eruptions by injecting aerosols into the stratosphere.

How cells turn mechanical forces into biochemical signals‎

Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response to its environment is always biochemical, mediated by the chemistry of its internal protein machinery. So how does a cell convert mechanical information into a molecular process? It's a long-standing mystery of cell biology, with various implications for cancer and other diseases.
