"Discovery of an Exception to a 200-Year-Old Law of Heat Transfer"

Researchers at the University of Massachusetts Amherst have discovered an exception to Fourier's Law, a 200-year-old scientific law governing heat transfer. Their study, published in the Proceedings of the National Academy of Sciences, reveals that pure electromagnetic radiation plays a role in heat diffusion through common materials like plastics and glasses, challenging the traditional understanding of heat transmission. The team's findings suggest that translucent materials allow energy to radiate internally, interacting with structural imperfections and becoming secondary heat sources, expanding our understanding of heat transmission and offering new strategies for designing heat circuits.

Study Reveals Surprising Reason for Fish Shrinking in Warming Waters

A study led by the University of Massachusetts Amherst found no physiological evidence supporting the Gill Oxygen Limitation (GOL) theory, which suggests that fish are shrinking due to limited oxygen supply from their gills as waters warm. Long-term experiments on brook trout revealed that increased temperatures led to decreased body size, but gill surface area did not explain the change. The findings challenge widely cited model projections of future global fisheries yields and highlight the need for interdisciplinary studies to understand the mechanisms governing fish size in a warming world.

"Advancing Bug-Free Software with AI-Generated Proofs"

A team of computer scientists at the University of Massachusetts Amherst has developed a new method, called Baldur, which leverages the power of Large Language Models to automatically generate whole proofs for software verification, yielding an unprecedented efficacy of nearly 66%. By using AI to generate mathematical proofs and working in tandem with a theorem prover, Baldur has shown a remarkable increase in accuracy, outperforming the state-of-the-art tool for automatically generating proofs. This advancement could bring bug-free software one step closer, as the capabilities of AI continue to be extended and refined.

Accidental Discovery Unveils Revolutionary Energy Generation from Thin Air

Scientists at the University of Massachusetts Amherst accidentally discovered a way to generate a small electrical current from humid air while working on a sensor for humidity. The researchers found that an array of microscopic tubes produced an electrical signal without power. They have since developed a methodology to test nanopores and created a device the size of a thumbnail that can generate a single microwatt of power. While still in the early stages, this hygroelectric power system has the potential for various applications and could provide an alternative to nonrenewable energy sources.
