UN: Falling clean energy costs can provide opportunity to boost climate action during COVID-19 recovery
If governments take advantage of the ever-falling price tag of renewables to put clean energy at the heart of COVID-19 economic recovery, they can take a big step towards a healthy world,…
Lessons learned during the COVID-19 pandemic
Exploring the unique ethical dilemmas raised by the COVID‐19 outbreak and how they have affected multiple sectors of society, both nationally and globally. Image credit: United Nations “This pandemic is a stark…
Reflecting sunlight to cool the planet could cause other unintended global changes
Scientists model the effects of spraying aerosols into the stratosphere and discover some unintended consequences. There is mounting interest in a global cooling strategy that uses solar geoengineering to limit the amount…
Smart molecules could be the key to computers with bigger memories
Researchers have discovered a single-molecule “switch” that can act like a transistor and offers the potential to store binary information. As we reach our computing capabilities, alternative means of storing and transferring…
How likely is it that COVID-19 will be a seasonal illness?
SARS-CoV-2 transmission appears to be affected by humidity, but experts warn that declines in summer months will not slow transmission enough to make a big dent. Image credit: Annie Spratt on Unsplash…
Human-on-a-chip provides an accurate model for the immune system
A new in vitro model of the body’s immune system better predicts its response to new therapeutics, potentially lowering the high costs and low success rates of drug discovery. Image credit: Hesperos…
Macrocycles help create green, fast-charging batteries
Researchers have created a fast-charging battery prototype that uses sodium instead of lithium, and macrocycles to store the chemical energy. Image credit: Dr. Florian Glöcklhofer Lithium-ion batteries have seen widespread success in…
As businesses reopen, it’s crucial we wear masks and safely distance
Mounting evidence suggests that the majority of SARS-CoV-2 infections occur through silent transmissions, where asymptomatic carriers spread virus-containing aerosols simply by speaking. Image credit: cromaconceptovisual Pixabay As countries around the world begin…
Making water-splitting for hydrogen storage 50 times more efficient
Experiments find the sweet spot for surface area and bubble trapping to create more efficient water-splitting devices. Image credit: Drew Hayes Unsplash Electrolysis is a technique used in chemistry to drive an…
