Mick Jagger released a pleasant surprise collaboration with Foo Fighters frontman Dave Grohl “Easy Sleazy,” which brushes through all of 2020s lowlights. “It’s a song that I wrote about coming out of lockdown, with some much needed optimism,” Jagger said in a statement Tuesday. “Thanks to Dave Grohl for jumping on drums, bass and guitar. It was a lot […]
Face masks that contain graphene may pose health risks
Health Canada is advising Canadians not to use face masks that contain graphene because there is a potential that they could inhale graphene particles, which may pose health risks. Graphene is a novel nanomaterial (materials made of tiny particles) reported to have antiviral and antibacterial properties. Health Canada conducted a preliminary scientific assessment after being […]
A sulfosugar from green vegetables promotes the growth of important gut bacteria
A team of scientists has analyzed how microbes in the gut process the plant-based, sulfur-containing sugar sulfoquinovose. Their study discovered that specialized bacteria cooperate in the utilization of the sulfosugar, producing hydrogen sulfide. This gas has disparate effects on human health: at low concentrations, it has an anti-inflammatory effect, while increased amounts of hydrogen sulfide […]
CBD may help avert lung destruction in COVID-19, research suggests
Cannabidiol, or CBD, may help reduce the cytokine storm and excessive lung inflammation that is killing many patients with COVID-19, researchers say. While more work, including clinical trials to determine optimal dosage and timing, is needed before CBD becomes part of the treatment for COVID-19, researchers at the Dental College of Georgia and Medical College […]
Seaspiracy, the latest Netflix documentary exposing the impact of our food systems, is making a splash
It was clear from the title and the promotion of the Netflix documentary Seaspiracy that it was going to adopt a similar approach to the highly influential 2014 documentary Cowspiracy, which uncovered the sheer scale and destructive impact of animal agriculture. Seaspiracy follows Ali, an activist and filmmaker who embarks on a journey of discovery which starts with beach […]
Estimating the environmental impact of Bitcoin mining
As an alternative to government-issued money, the cryptocurrency Bitcoin offers relative anonymity, no sales tax and freedom from bank and government interference. But some people argue that these benefits have an enormous environmental impact, particularly with regard to Bitcoin mining — the process used to secure the cryptocurrency. Now, researchers reporting in ACS’ Environmental Science & […]
Sugar not so nice for your child’s brain development, study suggests
Sugar practically screams from the shelves of your grocery store, especially those products marketed to kids. Children are the highest consumers of added sugar, even as high-sugar diets have been linked to health effects like obesity and heart disease and even impaired memory function. However, less is known about how high sugar consumption during childhood […]
Animal Pharm: Food For Thought
Mother Nature can no longer claim total dominion over the future of evolution. Some of the planet’s most commonly consumed animals are undergoing extensive genetic manipulation in laboratory settings across the globe. Scientists can create new breeds of cows, chickens and fish that grow faster, leaner and more muscular than ever before. Even fruits and […]
That Sugar Film
‘That Sugar Film’ is a highly informative, quirkily presented Australian documentary, which makes a case that the health fad of the past 30 years, which has demonized fats and has tended to minimize the perils of sugar may have contributed to the obesity epidemic now occurring worldwide, in a direct challenge to the hotly-contested ideas […]
Mixed signals: Combinations of estrogen-mimicking chemicals strongly distort hormone action
For years, scientists have been concerned about chemicals in the environment that mimic the estrogens found in the body. In study after study, researchers have found links between these “xenoestrogens” and such problems as decreased sperm viability, ovarian dysfunction, neurodevelopmental deficits and obesity. But experimental limitations have prevented them from exploring one of the most […]
