Berkeley researchers are exploring whether the Oz technology could help people with colour blindness.“We are now studying the science of boosting the colour dimensionality of signals going from the eye to the brain,” Ng said. “If it proves possible for a colour blind person to see full colour, the next question is whether a person with full colour could be boosted to yet a higher dimension of colour called tetrachromacy.”

This could contain colours beyond the rainbow that would need new names. Ng said that this is part of an ongoing scientific inquiry.Windram said success would depend on the cause of colourblindness in individuals. Deuteranomaly, which causes decreased sensitivity to green light, is the most common form of colour blindness.“In this case, a miniaturised version of this technology could theoretically be used to correct this by directly stimulating the cones when the correct colour of light hits them,” Windram said.

Windram pointed out that publicity materials for the research show images of the Oz experiment on a highly stabilised table.“This would require a lot of work to miniaturise the technology, and is likely a long way off. Given that the laser must stably hit the correct cones in order to stimulate them, this may not really be feasible as a form of vision correction technologically,” he said.

How do we know how people ‘see’ colour?

The concept of a colour has three main components, Windram explained: The physical, which has to do with the wavelengths of light that meet the eye; the neurological, which refers to how humans biologically process these light signals; and the societal or linguistic component, which pertains to how colours are named.By contrast, about six out of 10 LGBTQ adults said gay and lesbian people are generally accepted in the US.

A new poll by the Pew Research Centre has found that transgender people experience less social acceptance in the United States than those who are lesbian, gay or bisexual, according to LGBTQ adults.About six out of 10 LGBTQ adult participants in the poll said there is “a great deal” or “a fair amount” of social acceptance in the US for gay and lesbian people, according to “The Experiences of LGBTQ Americans Today” report released on Thursday.

Only about one in 10 said the same for non-binary and transgender people — and about half said there was “not much” or no acceptance at all for transgender people.The survey of 3,959 LGBTQ adults was conducted in January, after US President Donald Trump’s election, but just before his return to office when he set into motion a series of policies that question transgender people’s existence and their place in society.
