Google sacking
by ice up to 3 kilometres thick, but there is some tundra around the coastline. The wildfire is burning on tundra in the west of the country, near the small town of Sisimiut. Based on the colour of the smoke and the fact that the fire is spreading slowly, Jessica McCarty of Miami University in Ohio thinks that what is burning is not just the sparse surface vegetation, but also the peat underneath. According to local news reports, there are fears that with no rainfall expected, the fire could keep burning for a long time to come.
A GOOGLE employee’s 10-page memo criticising the firm’s efforts to increase workplace diversity has caused a stir in Silicon Valley. The memo was posted to an internal company discussion board last week by a software engineer, and shared widely. It suggests that Google’s efforts to promote gender diversity ignore biological differences between men and women. Such differences mean women have a stronger interest in people than in things, the author argues, which means they generally prefer jobs that

involve people rather than coding. He also says men have a higher drive for status, which is why they have more leadership roles. While it has historically been claimed that male and female brains are different, there is little in the way of modern neuroscience to support this idea. The public outcry in response to the document comes at an awkward time for Google, which is under investigation by the US Department of Labor for violating federal law by having gender disparities in salaries. On Monday, Google announced the employee had been fired.
Engineered salmon now on sale
THE “three-parent baby” technique offered by a New York fertility clinic should no longer be marketed, says the US Food and Drug Administration. Last year, New Scientist revealed that John Zhang of the New Hope Fertility Center had used his own mitochondrial replacement technique to create an embryo from a couple’s egg and sperm, plus mitochondrial DNA from another woman. This meant the couple didn’t pass on a fatal genetic mitochondrial disorder to the resulting child. Because the FDA had denied Zhang’s application for a licence to perform this procedure in people, the embryo was created in the US, but implanted into the mother’s uterus in Mexico. Now Mary Malarkey of the FDA has written to Zhang, saying that “such human subject research cannot legally be performed in the United States”. The websites of Zhang’s clinic and his biotech company Darwin Life promote the procedure as “the first proven treatment for certain genetic disorders” and “a cure for mitochondrial disease”. But mitochondrial replacement therapies cannot be marketed without a valid licence, says the FDA.
IT HAS taken 25 years, but after repeated controversies and much opposition from environmentalists, genetically modified salmon have made it to the marketplace. AquaBounty Technologies in Maynard, Massachusetts, announced last week that it has sold 4.5 tonnes of GM salmon fillets to unnamed customers in Canada, where the authorities last year approved the produce for sale as food. “The sale and discussions with potential buyers clearly demonstrate that customers want our fish,” said Ronald Stotish, chief executive of AquaBounty, in a statement. The engineered Atlantic salmon are equipped with a growth hormone gene from chinook salmon that PAUL DARROW/THE NEW YORK TIMES/REDUX/EYEVINE

dramatically increases how fast they grow. A second gene added from another fish, the ocean pout, accelerates growth by keeping the hormone gene on permanently. AquaBounty says the salmon grow twice as fast as typical salmon and consume 20 to 25 per cent less food per gram of new flesh. But the salmon, the first GM animal to go on sale in the world, has faced fierce resistance from environmental groups. They fear that any escapees from the tanks where the fish are reared on Prince Edward Island in eastern Canada would upset natural ecosystems by breeding with native salmon. The company says this shouldn’t happen because the fish are rendered sterile.
Hunting cosmic waves The LIGO (Laser Interferometer Gravitational-Wave Observatory) detector first heard the echo of two black holes colliding in 2015. Now, the Virgo detector in Italy has joined LIGO in the hunt for gravitational waves that warp space-time. Adding a planned third detector will help better pinpoint where the wavemaking collisions originate.
Trump’s Paris exit Last week, the US sent the UN official notification of its intention to withdraw from the Paris Agreement on climate change as soon as possible. The official rules of withdrawal mean the US must stay in the pact until at least 2020, and the UN secretary general says the US would be welcomed back if it changed its mind in future.
Catching cancer in time If your genes say you are likely to get cancer young, can you do anything about it? A study suggests annual whole-body MRI scans can catch tumours while they are still curable. Scans of 30 people at high genetic risk identified 16 hidden tumours – three of which were new cancers discovered in time to treat them (JAMA Oncology, doi.org/cbms).
Early-death divide People in northern England are 20 per cent more likely to die before the age of 75 than those in the south. An analysis of mortality data found that deaths between the ages of 25 and 44 have been rising in northern England since the mid1990s ( Journal of Epidemiology & Community Health, doi.org/cbmt).
Guide dog training Puppies receiving the most maternal care grow into adult dogs that lack the self-control and problem-solving ability of a successful guide dog – perhaps in part because overmothered pups aren’t sufficiently challenged early in life (PNAS, DOI: 10.1073/pnas.1704303114).
