Neuralink is developing a brain implant it hopes will help paralyzed people walk again and cure other neurological ailments.
The federal probe, which has not been previously reported, was opened in recent months by the US Department of Agriculture’s Inspector General at the request of a federal prosecutor, according to two sources with knowledge of the investigation.
The probe, one of the sources said, focuses on violations of the Animal Welfare Act, which governs how researchers treat and test some animals.
The investigation has come at a time of growing employee dissent about Neuralink’s animal testing, including complaints that pressure from CEO Musk to accelerate development has resulted in botched experiments, according to a Reuters review of dozens of Neuralink documents and interviews with more than 20 current and former employees. Such failed tests have had to be repeated, increasing the number of animals being tested and killed, the employees say.
The company documents include previously unreported messages, audio recordings, emails, presentations and reports. Musk and other Neuralink executives did not respond to requests for comment.
In all, the company has killed about 1,500 animals, including more than 280 sheep, pigs and monkeys, following experiments since 2018, according to records reviewed by Reuters and sources with direct knowledge of the company’s animal-testing operations. The sources characterised that figure as a rough estimate because the company does not keep precise records on the number of animals tested and killed. Neuralink has also conducted research using rats and mice.
The total number of animal deaths does not necessarily indicate that Neuralink is violating regulations or standard research practices. Current and former Neuralink employees say the number of animal deaths is higher than it needs to be for reasons related to Musk’s demands to speed research.
Through company discussions and documents spanning several years, along with employee interviews, Reuters identified four experiments involving 86 pigs and two monkeys that were marred in recent years by human errors. The mistakes weakened the experiments’ research value and required the tests to be repeated, leading to more animals being killed, three of the current and former staffers said.
Twitter faces more legal fallout over worker firings under Musk
Twitter is facing new legal fallout from mass layoffs under Elon Musk’s management, including complaints from some workers that severance payments are less than promised and from other employees that the company retaliated against them for exercising protected labor rights.
The latest legal actions follow a class-action lawsuit filed when the layoffs first began in early November which accused the company of failing to give enough notice to hundreds of employees facing termination.
A Los Angeles lawyer on Monday said she has filed individual arbitration claims on behalf of three employees who claim the company hasn’t committed to paying them the severance they were promised before Musk acquired it.
Lisa Bloom, the lawyer for the employees, said she’s prepared to bring hundreds more such complaints on behalf of Twitter employees and contractors. Unlike lawsuits that are filed and fought over publicly, arbitrations are handled in a closed-door process. BLOOMBERG
