Satellite imagery and AI reveal development needs hidden by national data‎

For years, Iceland, Switzerland, and Norway have ranked near the top of the United Nations' annual index of countries based on indicators of well-being and quality of life. Countries with more poverty and less access to health care and education tend to rank lower on the list, known as the Human Development Index, or HDI.

Renewable biological catalyst carries the potential to transform wastewater into phosphorus resource‎

Phosphorus is an essential nutrient for plants and managing its availability is critical for growing crops to maintain the global food supply. In an effort to move toward a more sustainable bioeconomy, researchers from the University of Illinois Urbana-Champaign and collaborators have developed a new method to recycle phosphorus from the biorefinery waste stream.

Extreme heat and drought at flowering could put future wheat harvests at risk, study suggests‎

New research shows that short periods of extreme heat and drought during flowering could become one of the biggest threats to global wheat production in the coming decades. As the climate changes, farmers around the world are facing more frequent and intense weather extremes.

Rhythm during sex in bonobos provides new insights into the evolution of communication‎

An international research team, including VUB data scientist Yannick Jadoul, has shed new light on the rhythmic nature of sexual behavior in bonobos. By precisely analyzing the tempo of movements during sex, researchers aim to better understand which building blocks of rhythm and communication are present in other species—and what this implies for the evolution of uniquely human traits such as speech and music. The study is published in the journal Evolution and Human Behavior.

Nitrogen pollution is rising: What a new global map means for forest carbon‎

On a cool spring morning in a northern forest, the ground feels soft underfoot. Mist hangs between the trunks, and the air smells of wet leaves and old humus; the slow alchemy that keeps a forest alive. Beneath the surface, billions of microbes break down organic matter and hair-thin roots exhale, releasing steady pulses of carbon dioxide. This process, known as soil respiration, is one of the largest carbon fluxes on the planet, usually so stable it feels almost like a steady heartbeat.

Silenced no more: Why U.S. online reviews turned longer and more negative‎

For years, consumers have quietly edited themselves online. A harsh review softened. A detail left out. A complaint never posted at all. New research shows that when the legal threat behind that silence disappears, the internet gets more honest, and more useful, almost immediately.

Scientists raise 300,000 surfclams offshore, proving open-ocean aquaculture can work‎

Rutgers researchers have made a discovery that could change the future of seafood farming in New Jersey. A study led by marine scientist Daphne Munroe has shown that Atlantic surfclams can be successfully farmed in the open ocean. Her research, published in the North American Journal of Aquaculture, proves that offshore aquaculture is not only possible but promising. This method could help meet the increasing demand for seafood while protecting wild clam populations.

Prehistoric fossil poses puzzles in shark research‎

A newly examined prehistoric shark from the age of dinosaurs provides surprising insights into the early evolution of modern sharks. It cannot be confidently assigned to any shark order that exists today and thus calls into question previous assumptions about the evolution of modern sharks.

State censorship shapes how Chinese chatbots respond to sensitive political topics, study suggests‎

Chinese chatbots may be censored by the state, according to a study published in PNAS Nexus. China has a robust program of censorship and all China-originating LLMs must be approved by the Chinese government before release.
