Light-activated material offers new approach to carbon dioxide conversion

Scientists have developed a new material that can use sunlight and water to convert carbon dioxide (CO₂) into carbon monoxide (CO)—a key building block for making fuels, plastics, pharmaceuticals and ...

Natural textile fibers may persist for more than a century in lake sediments

Natural fibers promoted as sustainable alternatives to plastic, including cotton and wool, have been found preserved in a U.K. lake for more than a century—challenging assumptions that they quickly ...

Decline in Japanese chum salmon linked to climate change

Using cow dung for sustainable carbon dioxide capture

Climate change is one of the most pressing global challenges in the present times. Increasing carbon dioxide (CO2) concentrations in the atmosphere are a major factor contributing to this phenomenon.

Scientists create a new state of matter at room temperature using light and nanostructures

Researchers at Rensselaer Polytechnic Institute (RPI) have created a new and unusual state of matter—known as a supersolid—by ...

AI model predicts chemical effects on gene expression, speeding drug discovery

Inside a diseased cell, the genes are in chaos. Some are receiving signals to overproduce a protein. Others are reducing ...

Why models and longitudinal data on adherence to non-pharmaceutical interventions must come together

An interdisciplinary team of authors from Canada, Austria, the U.S. and Germany has outlined how immuno-epidemiology and individual decision-making on non-pharmaceutical interventions (NPIs) can be ...

Nest-building birds help disperse cotton further than wind, study suggests

Birds play a larger role in the dispersal of wild cotton than previously assumed. This is shown by a study in the journal ...

Some Canadians are willing to eat insect-based food, but conditions apply

Bell-bottoms today, miniskirts tomorrow: Math reveals fashion's 20-year cycle

Fashion insiders and beauty magazines have long cited the "20-year-rule"—the idea that clothing trends often resurface every two decades. According to Northwestern University scientists, that ...

Ultrathin BiFeO₃ breaks the 30 nm limit, delivering fourfold stronger piezoelectricity

Piezoelectric materials, which convert mechanical stress into electricity and vice versa, are essential components in sensors, actuators, and energy-harvesting devices. However, the best piezoelectric ...

Past intensive whaling threatens the future of bowhead whales

A unique collection of prehistoric bowhead whale bones, dating back 11,000 years, reveals a previously untold story of the relative impacts of humans on nature. The time series of ancient fossils show ...
