A Barcelona-based startup called Inbrain Neuroelectronics has produced a novel brain implant made of graphene and is gearing up for its first in-human test this summer.

The technology is a type of brain-computer interface. BCIs have garnered interest because they record signals from the brain and transmit them to a computer for analysis. They have been used for medical diagnostics, as communication devices for people who can’t speak, and to control external equipment, including robotic limbs. But Inbrain intends to transform its BCI technology into a therapeutic tool for patients with neurological issues such as Parkinson’s disease.

Because Inbrain’s chip is made of graphene, the neural interface has some interesting properties, including the ability to be used to both record from and stimulate the brain. That bidirectionality comes from addressing a key problem with the metallic chips typically used in BCI technology: Faradaic reactions. Faradaic reactions are a particular type of electrochemical processes that occurs between a metal electrode and an electrolyte solution. As it so happens, neural tissue is largely composed of aqueous electrolytes. Over time, these Faradaic reactions reduce the effectiveness of the metallic chips.

That’s why Inbrain replaced the metals typically used in such chips with graphene, a material with great electrical conductivity. “Metals have Faraday reactions that actually make all the electrons interact with each other, degrading their effectiveness...for transmitting signals back to the brain,” said Carolina Aguilar, CEO and cofounder of Inbrain.

Because graphene is essentially carbon and not a metal, Aguilar says the chip can inject 200 times as much charge without creating a Faradic reaction. As a result, the material is stable over the millions of pulses of stimulation required of a therapeutic tool. While Inbrain is not yet testing the chip for brain stimulation, the company expects to reach that goal in due time.

The graphene-based chip is produced on a wafer using traditional semiconductor technology, according to Aguilar. At clean-room facilities, Inbrain fabricates a 10-micrometer-thick chip. The chip consists of what Aguilar terms “graphene dots” (not to be confused with graphene quantum dots) that range in size from 25 to 300 micrometers. “This micrometer scale allows us to get that unique resolution on the decoding of the signals from the brain, and also provides us with the micrometric stimulation or modulation of the brain,” added Aguilar.

Testing the Graphene-Based BCI

The first test of the platform in a human patient will soon be performed at the University of Manchester, in England, where it will serve as an interface during the resection of a brain tumor. When resecting a tumor, surgeons must ensure that they don’t damage areas like the brain’s language centers so the patient isn’t impaired after the surgery. “The chip is positioned during the tumor resection so that it can read, at a very high resolution, the signals that tell the surgeon where there is a tumor and where there is not a tumor,” says Aguilar. That should enable the surgeons to extract the tumor with micrometric precision while preserving functional areas like speech and cognition.

Aguilar added, “We have taken this approach for our first human test because it is a very reliable and quick path to prove the safety of graphene, but also demonstrate the potential of what it can do in comparison to metal technology that is used today.”

Aguilar stresses that the Inbrain team has already tested the graphene-based chip’s biocompatibility. “We have been working for the last three years in biocompatibility through various safety studies in large animals,” said Aguilar. “So now we can have these green lights to prove an additional level of safety with humans.”

While this test of the chip at Manchester is aimed at aiding in brain tumor surgery, the same technology could eventually be used to help Parkinson’s patients. Toward this aim, Inbrain’s system was granted Breakthrough Device Designation last September from the U.S. Food & Drug Administration as an adjunctive therapy for treating Parkinson’s disease. “For Parkinson’s treatment, we have been working on different preclinical studies that have shown reasonable proof of superiority versus current commercial technology in the [reduction] of Parkinson’s disease symptoms,” said Aguilar.

For treating Parkinson’s, Inbrain’s chip connects with the nigrostriatal pathway in the brain that is critical for movements. The chip will first decode the intention message from the brain that triggers a step or the lifting of the arm—something that a typical BCI can do. But Inbrain’s chip, with its micrometric precision, can also decode pathological biomarkers related to Parkinson’s symptoms, such as tremors, rigidity, and freezing of the gait.

By determining these biomarkers with great precision, Inbrain’s technology can determine how well a patient’s current drug regimen is working. In this first iteration of the Inbrain chip, it doesn’t treat the symptoms of Parkinson’s directly, but instead makes it possible to better target and reduce the amount of drugs that are used in treatment.

“Parkinson’s patients take huge amounts of drugs that have to be changed over time just to keep up with the growing resistance patients develop to the power of the drug,” said Aguilar. “We can reduce it at least 50 percent and hopefully in the future more as our devices become precise.”

In 2018, opioid overdoses in the United States caused one death every 11 minutes, resulting in nearly 47,000 fatalities. The most effective treatments for opioid use disorder (OUD) are three medications approved by the Food and Drug Administration (FDA): methadone, buprenorphine, and naltrexone.

Few correctional facilities in the United States have treatment programs for individuals with opioid use disorder (OUD), despite clear evidence that certain medications reduce the risk of overdose and death. Even in facilities where treatment is available, the COVID-19 pandemic has complicated efforts to provide such care.

Between 1999 and 2014, opioid use disorder (OUD) among pregnant women more than quadrupled, risking the health of the women—before and after giving birth—and their infants. As states grapple with COVID-19’s exacerbation of the opioid crisis, several are taking innovative steps to address the needs of high-risk groups, including low-income, postpartum patients with OUD.

As the coronavirus pandemic grips the world, the opioid epidemic continues to affect millions of Americans. Several states are developing innovative ways to tackle this public health issue. In this episode, we speak with Beth Connolly, who leads Pew’s research on substance use disorders, and Louisiana Representative Paula Davis, who helped ensure effective treatment in her state.

Sales of medically important antibiotics for use in food-producing animals increased 3% in 2019, according to recent data from the U.S. Food and Drug Administration. This is the second year in a row that the quantities of antibiotics sold for animal use have risen, underscoring the need for further FDA action to ensure judicious use of these lifesaving drugs.

The Food and Drug Administration published a concept paper in early January that describes a preliminary proposal for how the agency will ensure that companies developing antibiotics for administration to animals establish defined, evidence-based durations of use for all medically important antibiotics.

Johnson & Johnson must pay US$15 million (S$19.6 million) to a Connecticut man who alleges that he developed mesothelioma, a rare form of cancer, as a result of using the company's talc powder for decades, a jury found on Tuesday (Oct 15). Plaintiff Evan Plotkin sued the company in 2021 soon after his diagnosis, saying he was sickened by inhaling J&J's baby powder. The jury in Fairfield County, Connecticut Superior Court also found that the company should pay additional punitive damages, which will be determined later by the judge overseeing the case. "Evan Plotkin and his trial team are thrilled that a jury once again decided to hold Johnson & Johnson accountable for their marketing and sale of a baby powder product that they knew contained asbestos," Ben Braly, a lawyer for Plotkin, said in an email. Erik Haas, J&J's worldwide vice president of litigation, said in a statement that the company would appeal "erroneous" rulings by the trial judge that kept the jury from hearing critical facts about the case.

David Kearn argues that the idea that the first use of nuclear weapons since 1945 would be by the United States in the defense of Taiwan against a conventional Chinese invasion would have significant, negative, and long-lasting, diplomatic ramifications. It is difficult to fathom the myriad potential consequences, but U.S. nuclear weapon use would almost certainly shatter the non-proliferation regime as a functioning entity, incentivize states (including China) to acquire or improve their existing nuclear arsenal, and damage America's standing globally.

On March 13, President Vladimir Putin granted an interview, in which he again delved into the conditions under which he says he would initiate the use of nuclear weapons. His remarks were so ambiguous that it caused mainstream Western media organizations—which tend to agree on what to emphasize in news out of the Kremlin—to put divergent headlines on the news stories that they ran about this particular interview. “Putin, in Pre-Election Messaging, Is Less Strident on Nuclear War. The Russian leader struck a softer tone about nuclear weapons in an interview with state television,” was the NYT’s headline. In contrast, the FT’s headline was “Russia ‘prepared’ for nuclear war, warns Vladimir Putin. President resumes bullish rhetoric over use of atomic arsenal if west threatens Moscow’s sovereignty,” while CBS News ran with “Putin again threatens to use nuclear weapons, claims Russia's arsenal ‘much more’ advanced than America's” and WSJ led with “Putin Rattles Nuclear Saber Ahead of Presidential Elections; Raising specter of nuclear confrontation.” So, which is it? Has Putin just struck a softer tone about nuclear weapons or has he rattled his nuclear saber yet again? The answer is both.

Would the world be safer if the United States pledged to never use nuclear weapons first? Supporters say a credible pledge would strengthen crisis stability, decrease hostility, and bolster nonproliferation and arms control. But reactions to no-first-use pledges by the Soviet Union, China, and India suggest that adversaries perceive pledges as credible only when the political relationship between a state and its adversary is already relatively benign, or when the state’s military has no ability to engage in nuclear first use against the adversary.
