Oscillating gel gives synthetic materials the ability to 'speak'

Researchers at the University of Pittsburgh have discovered a synthetic material that can rebuild itself through chemical communication and interaction with light. The material, known as Belousov-Zhabotinsky (BZ) gel, exhibits autochemotaxis, allowing it to move in response to chemical signals and follow given actions or commands.

Like a game of poker, school programs' success can hinge on principals going 'all in'

A new study published by the University of Pittsburgh and the University of Virginia found that school principals' level of enthusiasm and support plays a critical role in teachers' ability to successfully implement school programs. Without principal support, teachers view administrators as a hindrance to program success, while enthusi...

The aftermath of calculator use in college classrooms

A study by Pitt researcher Samuel King found that students relying on calculators to solve mathematical problems often lack a deeper understanding of the underlying concepts. The research suggests that using calculators as a substitute for mathematical thinking can lead to surface-level learning, rather than true comprehension.

Why living in the moment is impossible

A study at the University of Pittsburgh has identified a brain area responsible for using past decisions and outcomes to guide future behavior, suggesting that living in the moment is impossible due to the need for continuity of thought. The frontal eye field and supplementary eye field were found to play key roles in metacognition.

Smart Materials get SMARTer

Researchers at University of Pittsburgh and Harvard University created self-regulating microscopic materials that can continuously sense and regulate temperature. The new material, called SMARTS, offers a customizable way to trigger chemical reactions on cue and reproduce stable feedback loops found in biological systems.

Researchers able to better pinpoint history of droughts through exploration of tree rings

Researchers at the University of Pittsburgh have discovered an unexpected complexity in the patterns of drought during the Middle Ages. The study uses tree rings and oxygen isotopes to reveal that winters were wetter-than-expected during the Medieval Climate Anomaly, contradicting previous tree ring data.

Pitt researchers link neural variability to short-term memory and decision making

Researchers at the University of Pittsburgh have found that fluctuations in brain activity impact cognitive tasks, leading to errors in short-term memory. By understanding how neural variability relates to cognitive functions, the team aims to provide important clues about the neural mechanisms that support cognition.

Important clue uncovered for the origins of a type of supernovae explosion

A research team at the University of Pittsburgh used the Sloan Digital Sky Survey to determine that the merger of double white dwarfs is a plausible explanation for Type Ia supernovae. The study found that one double white dwarf merger event occurs in the Milky Way about once a century, remarkably close to the rate of observed Type Ia ...

Pitt researchers coax gold into nanowires

Researchers at the University of Pittsburgh have created a self-assembly method to grow gold nanowires, which can be used to detect poisonous gases such as hydrogen sulfide in natural gas. The gold nanowires are highly conductive and can detect gas levels comparable to existing sensing techniques.

Adolescents' brains respond differently than adults' when anticipating rewards

Researchers found increased brain cell activity in adolescent rats in an unusual area called the dorsal striatum, associated with habit formation and decision-making. This suggests that adolescents may be more susceptible to developing disorders like addiction and depression due to their unique brain response to reward.

Healing the iPhone's wounds

A team of researchers from Pitt and UMass proposes a 'repair-and-go' approach to fix malfunctions caused by small-surface cracks on any digital device. This method uses nanoparticles and droplets of oil to repair defects on-site, potentially extending the device's lifetime.

Post-silicon computing

The University of Pittsburgh has received a $1.8 million grant to create a new kind of computer using a tiny 'toy' with big potential. The project aims to develop a scalable sensing, storage, and computation platform, enabling the creation of high-tech industries and jobs in the United States.

How the Milky Way got its spiral

A supercomputer simulation by University of Pittsburgh researcher Christopher W. Purcell suggests that the Milky Way's spiral arms were triggered by a collision with the Sagittarius Dwarf galaxy. The impact stripped off 80-90% of the dark matter halo, producing instabilities that eventually formed the spiral arms and ring structures.
