A low-cost, portable radiation dosimetry system uses a smartphone and radiochromic film to provide immediate on-site dose assessments of radiation.

Antibiotics that save lives can also become hidden environmental threats once they leave hospitals and households. A new study reports an innovative solution that transforms sewage waste into a low cost, eco friendly sensor capable of detecting trace levels of the widely used antibiotic trimethoprim in water, urine, and pharmaceutical samples.

Biochar, a carbon rich material made by heating agricultural and forestry waste under low oxygen conditions, has long been valued for improving soil health. Now, a new review reveals that biochar is rapidly evolving into a powerful multifunctional material with the potential to tackle some of the world’s most urgent environmental challenges, from water pollution and nutrient loss to carbon emissions and clean energy production.

In research that could shed light on the growth and formation of complex tissue architectures, Brown University engineers show how cells orbit and reconfigure their surroundings to venture outward from confined spheroids.

Pilot whale samples from 1986-2023 show that legacy PFAS are declining in the open ocean. Newer PFAS remain a major unknown and may be accumulating in near-source environments.
