Elon Musk’s brain-implant company Neuralink has been given clearance from the U.S. Food and Drug Administration (FDA) to carry out its first trials in humans, according to news reports.

Neuralink aims to use its brain-computer interface (BCI) technology to restore movement in people with quadriplegia, meaning complete or partial paralysis of the arms, legs and trunk. Musk has also said that the brain implants could be used to restore sight in blind people. 

Neurons, or nerve cells, communicate via electrical signals to coordinate our thoughts, feelings and behavior. Neuralink’s implants, which have only been tested in animals, would theoretically work by interpreting these electrical signals and transmitting the decoded information to a computer via Bluetooth. In the case of helping to restore movement, for example, the computer would then analyze the incoming information and respond by sending signals back to the body, stimulating nerves and muscles to control movement. 

The implant is inserted into a small hole in the skull created by a surgery-performing robot and the implant’s electrodes are then embedded just a few millimeters into the cortex, the brain’s outer layer. The procedure can be done in 30 minutes, without general anesthesia, Musk has claimed — although again, this has never been attempted in humans.

Neuralink is not the only company working on BCI technology. For example, in 2022 Synchron implanted its Stentrode system into its first human patient after gaining FDA clearance to begin in-human trials; the device is designed to let people with paralysis operate assistive technologies using only their thoughts. Synchron also aims to restore movement in severely paralyzed people, according to Forbes.

Musk once reportedly approached Synchron’s founder about a potential deal. This approach came just months before a federal investigation into Neuralink was launched to look into potential violations of animal welfare and Neuralink staff raised complaints that the company’s animal testing was being rushed, leading to unnecessary animal suffering and deaths, Reuters reported.

An animal rights group, the Physicians Committee for Responsible Medicine (PCRM), filed a complaint in February 2022 that accused Neuralink of “botching surgeries.” The group claimed that surgeons had used an unapproved glue on two occasions to fill the holes in the monkeys’ skulls, which then leaked onto the animals’ brains and ultimately killed them. Separately, based on a PCRM tip, the Department of Transportation is investigating whether Neuralink is taking the required precautions when transporting implants that have been removed from monkey brains. RELATED STORIES—Electrical zaps can ‘reawaken’ lost neural connections, helping paralyzed people walk again

Neuralink has killed an estimated 1,500 animals since 2018, including sheep, pigs and monkeys, Reuters reported. While it is unclear how many died due to complications with Neuralink’s brain implants, Futurism reported that, in one Neuralink experiment involving 23 monkeys, five, or 21%, of the test subjects were euthanized due to device-related issues.

Neuralink’s first attempt at gaining FDA approval in 2022 was rejected on safety grounds, according to an exclusive Reuters report. Musk, however, remains confident in the safety of Neuralink, claiming that he would be willing to implant the technology in his children’s brains and even his own brain.

The upcoming in-human trials must prove the safety and efficacy of Neuralink’s brain implants before they can become FDA-approved and widely available. Recruitment for clinical trials is not yet open, Neuralink wrote in a tweet.

Heidi Alexander says ‘fairness’ will be government’s ‘guiding principle’ when it comes to taxes at next budget

Heidi Alexander says 'fairness' will be government's 'guiding principle' when it comes to taxes at next budget

Another hint that tax rises are coming in this autumn’s budget has been given by a senior minister.

Speaking to Sunday Morning with Trevor Phillips, Transport Secretary Heidi Alexander was asked if Sir Keir Starmer and the rest of the cabinet had discussed hiking taxes in the wake of the government’s failed welfare reforms, which were shot down by their own MPs.

Trevor Phillips asked specifically if tax rises were discussed among the cabinet last week – including on an away day on Friday.

Tax increases were not discussed “directly”, Ms Alexander said, but ministers were “cognisant” of the challenges facing them.

Asked what this means, Ms Alexander added: “I think your viewers would be surprised if we didn’t recognise that at the budget, the chancellor will need to look at the OBR forecast that is given to her and will make decisions in line with the fiscal rules that she has set out.

“We made a commitment in our manifesto not to be putting up taxes on people on modest incomes, working people. We have stuck to that.”

Ms Alexander said she wouldn’t comment directly on taxes and the budget at this point, adding: “So, the chancellor will set her budget. I’m not going to sit in a TV studio today and speculate on what the contents of that budget might be.

“When it comes to taxation, fairness is going to be our guiding principle.”

Afterwards, shadow home secretary Chris Philp told Phillips: “That sounds to me like a barely disguised reference to tax rises coming in the autumn.”

He then went on to repeat the Conservative attack lines that Labour are “crashing the economy”.

Mr Philp then attacked the prime minister as “weak” for being unable to get his welfare reforms through the Commons.

Discussions about potential tax rises have come to the fore after the government had to gut its welfare reforms.

Sir Keir had wanted to change Personal Independence Payments (PIP), but a large Labour rebellion forced him to axe the changes.

With the savings from these proposed changes – around £5bn – already worked into the government’s sums, they will now need to find the money somewhere else.

The general belief is that this will take the form of tax rises, rather than spending cuts, with more money needed for military spending commitments, as well as other areas of priority for the government, such as the NHS.
