LIFE-SAVING DRINKING WATER DISINFECTANTS HAVE A “DARK SIDE”

Disinfecting drinking water against pathogens is necessary, but by-products from the process are a ubiquitous — and likely growing — problem across the U.S. Solutions exist, though.

 

Better diet and glucose uptake in the brain lead to longer life in fruit flies

Researchers from Tokyo Metropolitan University have discovered that fruit flies with genetic modifications to enhance glucose uptake have significantly longer lifespans. Looking at the brain cells of aging flies, they found that better glucose uptake compensates for age-related deterioration in motor functions, and led to longer life. The effect was more pronounced when coupled with dietary restrictions. This suggests healthier eating plus improved glucose uptake in the brain might lead to enhan​

 

Changing diets—not less physical activity—may best explain childhood obesity crisis

Variation in consumption of market-acquired foods outside of the traditional diet—but not in total calories burned daily—is reliably related to indigenous Amazonian children's body fat, according to a Baylor University study that offers insight into the global obesity epidemic.

 

Parrots pushed to extinction despite protection policies

Habitat destruction by logging and agriculture is pushing parrot species towards extinction, while current protected areas are failing to mitigate these effects, according to new research. The study also shows that in many regions across the globe, including Australia, the future of parrots is in the hands of policy makers.

 

This underwater robot cleans ships to cut emissions and protect marine ecosystems

A new robot ship cleaner is being hailed as a breakthrough in the battle against marine fouling. Jotun, a Norwegian paint maker, has produced HullSkater, an underwater machine that cleans a ship's hull and prevents the build-up of fouling. Holding itself to the ship by powerful magnets, the robot removes marine life before it becomes established.

 

EPA: Hawaii’s Military Bases Dumped 630,000 Pounds Of Toxic Nitrate Into The Ocean

U.S. military bases in Hawaii dumped more than half a million pounds of nitrate compounds — toxic chemicals commonly found in wastewater treatment plants, fertilizers and explosives — into the ocean in 2019, newly released federal data shows.

 

My lungs are as bad as my dad's who is 72 and smoked all his life

When it comes to Covid, our lungs are ‘ground zero’. They are one of the primary routes the virus uses to get into the body. But early on in the pandemic, chest X-ray scans revealed something else: where the images should be black, indicating healthy air-filled tissue, in many cases there was a white mist described as resembling ‘ground glass’.

 

Lead Poisoning Of Children: Stanford researchers and others reveal pervasive health threats of unregulated battery recycling

A remediation and public education effort at an abandoned battery recycling facility in Bangladesh eliminated most lead soil contamination, but levels of the toxic metal in children living near the site did not decrease nearly as much. The discrepancy reveals the scope of other lead exposure sources and the challenge they present to public health.

 

How spicy chili peppers could be the key to cheap, efficient and abundant solar energy

Spicy chili peppers may be the key to cheap, efficient and abundant solar energy, scientists contend. A pinch of capsaicin, the compound that gives peppers their well-known bite, can give regular solar cells virtually the same power output as the most expensive panels created to date.

 

We Need to Talk About The Rapid Decline in Insects Around The World

Apocalypse or revolution? Depending on the study making headlines, insect numbers around the world are either in dramatic freefall or simply an alarming state of flux, with some species even benefiting from changes in climate.
