The number of hours of light exposure we experience affects how we eat and how we burn energy. This may help us understand the link between seasons and metabolism.

The growing global population needs sufficient food. Its production causes overfertilization and increased nitrogen concentration in agriculture, which negatively affects the population, climate, and ecosystems. According to new models, however, today’…

Scientists have theoretically predicted that light can be bent under pseudogravity. A recent study by researchers using photonic crystals has demonstrated this phenomenon. This breakthrough has significant implications for optics, materials science, an…

Playing a single 18-hole round of golf or completing 6 km of either Nordic walking or regular walking may significantly improve immediate cognitive function in older individuals.

Forensic fibers can survive underwater for much longer than previously thought — which could help criminal investigators uncover vital evidence. New research has found that fiber evidence can survive on fabrics underwater for several weeks.

A study describes the productive forces of the Chalcolithic communities of the southern half of the Iberian Peninsula as being very diverse, both in the type of tasks performed and in intensity, with a high degree of cooperation and no apparent signs o…

A new study that examines both the physical and socioeconomic effects of sea-level rise on Florida’s Miami-Dade County area finds that in coming decades, four out of five residents may face disruption or displacement, whether they live in flood zones o…

A research team has discovered a fundamental mechanism that helps the dreaded hospital pathogen Acinetobacter baumannii to survive. This mechanism explains why the pathogen is difficult to eradicate in hospitals and why infections flare up again and ag…

When Hurricane Ian struck southwest Florida in September 2022, it unleashed a variety of Vibrio bacteria that can cause illness and death in humans, according to a new study.

Researchers have identified a new biomarker that can predict whether or not neurons will regenerate after an injury. The findings could help scientists develop regenerative therapies for spinal cord injuries and other neurological conditions.

The heat shock response of cells is a classic model of biological adaptation, part of the fundamental processes of life — conserved in creatures from single-celled yeast to humans — that allow our cells to adjust to changing conditions in their envir…

Researchers have developed a visualization tool that combines high-speed cameras and fluorescent injection to distinguish tumor tissue from normal tissue across cancer types. The team evaluated the new imaging technology, known as fluorescence lifetime…

One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental cond…

Despite steps toward decreasing deforestation, uncontrolled wildfires are threatening environmental gains in Brazilian Amazonia, one of the world’s most critical carbon sinks and a region of high biological and cultural diversity.  

A multiyear analysis tested whether management zone maps based on soil conditions, topography or other landscape features can reliably predict which parts of a cornfield will respond best to higher rates of seeding or nitrogen application. The study fo…
