Scientists adding human brain genes to monkeys — it’s the kind of thing you’d see in a movie like Rise of the Planet of the Apes. But Chinese researchers have done just that, improving the short-term memories of the monkeys in a study published in March in the Chinese journal National Science Review. While some experts downplayed the effects as minor, concerns linger over where the research may lead. The goal of the work, led by geneticist Bing Su of Kunming Institute of Zoology, was to investigate how a gene linked to brain size, MCPH1, might contribute to the evolution...

For the first time, a team of Chinese scientists made use of gene-editing techniques to make monkey brains more human-like. By the end, the monkeys, rhesus macaques, got smarter and had superior memories as compared to the unaltered monkeys. Researchers edited the human version of a gene known as ‘MCPH1’ into the macaques. The gene made the monkeys’ brain develop along a more human-like timeline

Making monkeys more smart and human-like, scientists have used gene-editing to insert human brain gene in a monkey. For the first time, a team of Chinese scientists made use of gene-editing techniques to make monkey brains more human-like. By the end, the monkeys, rhesus macaques, got smarter and had superior memories as compared to the unaltered monkeys. Researchers edited the human version of a gene known as ‘MCPH1’ into the macaques. The gene made the monkeys’ brain develop along a more human-like timeline. The gene-hacked monkeys showed better reaction times and improved short-term memories in comparison to their unaltered peers,...

In 1981, when Wil Roebroeks of Leiden University was beginning his archaeological career, he ran across some red stains in the grayish sediments on the floodplain of the Maas River where his team was excavating. The site, called Maastricht-Belvèdère, in The Netherlands, was occupied by Neanderthals at least 200,000 years ago. Roebroeks collected and stored samples of the red stains, and 30 years later he received funding to analyze them. It became apparent that he and his team had discovered the earliest evidence of hominins using the mineral iron oxide, also known as ocher. Until now, the use of...
