The Link Between Air Pollution and Irreversible Sight Loss Image Credit: Tatiana Grozetskaya / Shutterstock.com A new study points towards an association between small particle pollution and age-related macular degeneration. An increased risk of progressive and irreversible sight loss through age-related macular degeneration (AMD) could arise from air pollution, in particular, from small particulate matter suggests a large study¹ recently conducted in the UK.  Whilst previous research had linked pollution and glaucoma, this new paper indicates that even a small rise in air pollution can tri...

Pointing Graphene Nanochannel Water Filters in the Right Direction Image Credit: SedovaY / Shutterstock.com New research indicates that a novel method of fabricating graphene stacks could greatly benefit water filtration.  The spaces that form when sheets of nanomaterials like graphene  —  layers of single atoms  —  are stacked atop each other have been utilized by scientists in a wide range of applications. One of the potential uses for such gaps  —  more formally known as nanochannels  —  is in the filtration of water and other liquids, removing nanoscale contaminan...

The Development of a Facemask Sensor that can Detect COVID-19 The team from UC San Diego is working on a color-changing testing strip that can detect the SARS-CoV-2 virus in the user's saliva or even breath. Image Credit: UC San Diego Researchers from the University of California San Diego are in the process of developing a new sensor to help the fight against COVID-19. The team is working on a color-changing testing strip that can detect the SARS-CoV-2 virus in the user's saliva or even breath. The strip can be attached to face masks meaning it has the potential to provide simple, effectiv...

The Devastating Effect that Wildfires have on Air Quality Image Credit: SvetlanaSF / Shutterstock.com Driven by climate change, wildfires are on the rise. New studies highlight the burden of such events on communities and human health.  Wildfire activity is on the rise across the globe due to the continuing effects of global warming. The joint warmest year on record, 2020, was a year of wildfires thanks to dry conditions and droughts, driven by climate change, with over 45 million acres of land lost in Australia alone.  These configurations represent an increasingly devastating and often ...

New Perovskite Sensor Mimics the Human Eye Image Credit: CG Alex / Shutterstock.com A newly developed retinomorphic sensor that operates like the mammalian eye could help change the way computer processors operate.  One thing has always eluded programmers and engineers; the ability to build a computer that 'thinks' like a human brain. A new type of sensor that processes information like the human eye could hold the key to this computing breakthrough, speeding up information processing and cutting down energy demands. The 'retinomorphic' device developed by a team of researchers from Oregon U...
