Carbon capture takes sponge-like form with new cost-effective method

Ball-and-stick model of carbon dioxide. Credit: Wikipedia An international team of scientists is using porous, sponge-like materials that can trap carbon dioxide in their cavities while allowing other gases such as nitrogen to pass through. The materials are made from sugar and low-cost alkali metal salts, so they would be inexpensive enough for large-scale deployment,… Continue reading Carbon capture takes sponge-like form with new cost-effective method

Your Navigation Skills Depend on Where You Grew Up

Where a person grows up as a child significantly impacts their navigation skills as an adult, according to recent research. Those who grew up in cities have a worse sense of direction compared to those who lived in rural areas. And understanding the impact of these navigational skills could shed light on diagnosing dementia. Navigation… Continue reading Your Navigation Skills Depend on Where You Grew Up

Under anaerobic conditions, common microbial communities can break the ultra-strong carbon-fluorine bond

Credit: Yaochun Yu et al, Environmental Science & Technology (2022). DOI: 10.1021/acs.est.1c05509 Engineers at University of California Riverside are the first to report selective breakdown of a particularly stubborn class of PFAS, called fluorinated carboxylic acids (FCAs), by common microorganisms. Under anaerobic conditions, a carbon-carbon double bond is crucial for the shattering the ultra-strong carbon-fluorine… Continue reading Under anaerobic conditions, common microbial communities can break the ultra-strong carbon-fluorine bond

New study explains how to broaden strategy to avert catastrophic climate change

Credit: CC0 Public Domain Slashing emissions of carbon dioxide, by itself, cannot prevent catastrophic global warming. But a new study concludes that a strategy that simultaneously reduces emissions of other largely neglected climate pollutants would cut the rate of global warming in half and give the world a fighting chance to keep the climate safe… Continue reading New study explains how to broaden strategy to avert catastrophic climate change

One dirty pool, many cases of E. coli: Summer’s swimming danger

As the weather warms and families flock to pools, dirty water may dampen the fun. Swimmers at a Pennsylvania community pool learned that the hard way in June 2021, when more than a dozen kids were seriously sickened by two types of bacteria, E. coli and C. difficile. “These are pathogens that can cause pretty… Continue reading One dirty pool, many cases of E. coli: Summer’s swimming danger

As revolutionary as it was, the tool had… Continue reading New ‘CRISPR-Combo’ method boosts genome editing power in plants

People enter a ‘dissociative state’ when using social media

In a project led by the University of Washington, researchers showed that some people enter a state of dissociation similar to daydreaming when surfing social media. The team designed an app called Chirp, which was connected to participants’ Twitter accounts. Through Chirp, users’ likes and tweets appear on the real social media platform, but researchers… Continue reading People enter a ‘dissociative state’ when using social media

South Asia’s intense heat wave a ‘sign of things to come’

A woman covers her face with a scarf to protect from heat wave rides through a dust storm in Ahmedabad, India, Saturday, May 21, 2022. The intense heat wave sweeping through South Asia was made more likely due to climate change and it is a sign of things to come. An analysis by international scientists… Continue reading South Asia’s intense heat wave a ‘sign of things to come’
