An ancient brain circuit, which enables the eyes to reflexively rotate up as the body tilts down, tunes itself early in life as an animal develops, a new study finds. 

A new study investigating ancient methane trapped in Antarctic ice suggests that global increases in wildfire activity likely occurred during periods of abrupt climate change throughout the last Ice Age.

Hula hooping is so commonplace that we may overlook some interesting questions it raises: “What keeps a hula hoop up against gravity?” and “Are some body types better for hula hooping than others?” A team of mathematicians explored and answered these questions with findings that also point to new ways to better harness energy and improve robotic positioners. 

A team led by Columbia Engineering researchers and collaborators report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These "all-optical" nanosensors are probed with light only and therefore allow for fully remote read-outs -- no wires or connections are needed.

Three years after the Dec. 30, 2021, Marshall Fire destroyed more than 1,000 homes in Boulder County, two new studies offer insight into what happens to air quality and health in the aftermath of urban wildfires.

A groundbreaking study led by Prof. Omar S. Magaña-Loaiza and his team at the Quantum Photonics Laboratory from LSU has unveiled a remarkable breakthrough in understanding the quantum and classical worlds. Published in PhotoniX, the study demonstrates the isolation of quantum many-body systems from classical light fields, revealing quantum behaviors in a seemingly classical domain.

Published in the journal Scientific Reports, researchers have created realistic, skin-like replicas made of Ecoflex, a type of silicone rubber that can potentially serve as a platform to evaluate risks of bacterial infections from intravenous catheters and test wearable sensors, among other biomedical applications. The study found that EcoFlex-based skin replicas can be engineered to mimic actual skin textures, wettability, and elasticity, simulating the conditions where bacteria grow and adhere.
