Electric cooker an easy, efficient way to sanitize N95 masks, study finds

A new study found that 50 minutes of dry heat in an electric cooker decontaminated N95 respirators inside and out while maintaining their filtration and fit. This could enable wearers to safely reuse limited supplies of the respirators. …read more

Study finds high levels of toxic pollutants in stranded dolphins and whales

Study finds high levels of toxic pollutants in stranded dolphins and whales

Researchers examined toxins in tissue concentrations and pathology data from 83 stranded dolphins and whales from 2012 to 2018. They looked at 11 different animal species to test for 17 different substances. The study is the first to report on concentrations in blubber tissues of stranded cetaceans of atrazine, DEP, NPE and triclosan. It also is the first to report concentrations of toxicants in a white-beaked dolphin and in Gervais’ beaked whales. …read more

Mix of contaminants in Fukushima wastewater, risks of ocean dumping

Mix of contaminants in Fukushima wastewater, risks of ocean dumping

Nearly 10 years after the Tohoku-oki earthquake and tsunami devastated Japan’s Fukushima Dai-ichi Nuclear Power, radiation levels have fallen to safe levels in all but the waters closest to the shuttered power plant. A new article looks at the many radioactive elements contained in the tanks and suggests that more needs to be done to understand the potential risks of releasing wastewater from the tanks into the ocean. …read more

Scientists discover new penguin colonies from space

A new study using satellite mapping technology reveals there are nearly 20% more emperor penguin colonies in Antarctica than was previously thought. The results provide an important benchmark for monitoring the impact of environmental change on the population of this iconic bird. …read more

New molecule reverses Alzheimer’s-like memory decline

New molecule reverses Alzheimer’s-like memory decline

A drug candidate previously shown to slow aging in brain cells, successfully reversed memory loss in a mouse model of inherited Alzheimer’s disease. The new research also revealed that the drug, CMS121, works by changing how brain cells metabolize fatty molecules known as lipids. …read more
