How well do you know Palestine?

“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.“In the end I may see a colour and call it ‘red’, someone else may call it ‘rot’ or ‘rouge’ … but also another may look at it a bit more closely and say ‘well it’s claret’ or ‘crimson’.”To test this, neuroscience and AI researcher Patrick Mineault developed a

for entertainment purposes in September 2024, on which users can take a test to see how their colour perception compares to others.Humans can also perceive colour differently due to differences in factors such as “temperature” of light. This was demonstrated when a photo of a dress went viral in 2015, dividing social media users over whether the dress was white and gold, or blue and black.

Windram explained that people who were deciding what colours the dress was were drawing on preconceived notions of whether the photograph of the dress was taken in warm lighting or cool lighting.

Do animals see colour differently from humans?According to Caren Kiarie, a human rights activist from neighbouring Kisumu County, the church has several branches across the Kenyan Nyanza region, and sends members from one location to the other.

Many people came to worship and live within the church full time, Opapo villagers remember.“They were very friendly people who did business around the Opapo area and interacted well with the people here,” Juma said. “But they would never live outside the church, as they all went back inside in the evening. Within the church compound, they had cattle, sheep, poultry and planted crops for their food.”

Though the worshippers could interact with outsiders, locals say the children living there – some with their parents and others who neighbours said were taken in alone – never attended school, while members were barred from seeking medical care if they were sick.On the day of the police raid and rescue, many of the worshippers looked weak and ill, said Juma, who over the years befriended some young people whose parents belonged to the church. “They were sickly, as they were never allowed to go to the hospital or even take pain medication,” he said, quoting what his neighbours had told him. Auma believes those who were rescued that day were the sickly ones, as the others had escaped.
