Researchers have, for the first time, directly observed the flow of water beneath the ice of West Antarctica.
Microalgae remove antibiotic residues from wastewater, reducing environmental contamination
By Thais Szegö | Agência FAPESP – Microalgae of the species Monoraphidium contortum have the ability to remove antibiotic residues from water, especially sulfamethoxazole and trimethoprim.
Viruses that combat algal blooms may actually increase risks for people and ecosystems
New laboratory research shows that when viruses attack a species that forms toxic algal blooms, those thick, blue-green slicks that choke waterways and that threaten ecosystems, drinking water, and public health, what results might be even worse than before the infection.
Study finds antibiotics from human use are contaminating rivers worldwide
Researchers estimated about 8,500 tonnes of antibiotics end up in river systems each year after passing through the human body and wastewater systems
Engineers develop sponge-like device to capture water from air and release it under sunlight
Engineers from Australia and China have invented a sponge-like device that captures water from thin air and then releases it in a cup using the sun's energy, even in low humidity where other technologies such as fog harvesting and radiative cooling have struggled.
