Through Rose-tinted Contact Lenses: Gold Nanocomposites Help the Color-Blind See the World Differently

Using red-tinted glasses can make colors more prominent, but achieving this correction in a comfortable manner is more challenging. 

By Jade Sterling

A collaborative team of researchers from Khalifa University and Imperial College London has developed a new contact lens that could help people with color blindness. Rather than the conventional approach, using dyes to tint lenses, the research team uses gold nanoparticles to filter red and green light, creating a safer way to see colors.

Investigating the Sociodemographic Factors in Symptomatic and Asymptomatic Covid-19 Cases

By Jade Sterling

Knowing what makes a patient more or less likely to be a silent carrier could help protect the population and prevent the spread of Covid-19.

Emerging in Wuhan in December 2019, Covid-19 rapidly spread across the globe through sustained human-to-human transmission. Affecting over 77 million people and causing over 1.7 million deaths, the Covid-19 pandemic proved difficult to control, in large part due to asymptomatic cases and the ease of its transmission.

Imaging Organic Matter in 12,000 Year Old Fossils for the First Time

By Jade Sterling

A team of researchers have discovered a new way to see organic matter inside of fossilized ‘diatoms’ –  a type of microalgae – using powerful microscopy imaging techniques, which could help scientists better understand the conditions and climate of the Earth thousands of years ago.

Diatoms are one of the most prolific microscopic sea organisms that serve as food for many animals. Beyond that though, diatoms – which include around 16,000 species – can be preserved in the sediment record, offering clues into what life was like on Earth in the past.
