Video Shows First Neuralink Patient Playing Mario Kart With His Mind

The first patient with a Neuralink brain-computer implant played Nintendo’s Mario Kart video game with his mind in an impressive new demo video, calling it “lifechanging” at a company-wide meeting that was posted Friday on the social media platform X-formerly-Twitter.

“It’s been a wild ride,” said Noland Arbaugh, the 29-year-old Neuralink patient, during the celebratory company meeting.

“This is going to change the world,” added Arbaugh, who’s quadriplegic, meaning he’s paralyzed below his neck from a swimming accident, and requires the use of a wheelchair.

Researchers identify protein sensor that plays a role in lung fibrosis

Researchers at Weill Cornell Medicine have discovered a protein called SEL1L that plays a critical role in clearing collagen from tissue, and that may be a therapeutic target to help prevent fibrosis, scar tissue that interferes with organ function. The paper, published on Feb. 20 in Nature Communications, provides clues that could lead to drug development for diseases like lung fibrosis which have no therapeutic options currently.

Multiomic approach boosts disease prediction accuracy beyond traditional methods

🧬🔬📊

In a recent study published in the journal Nature Aging, researchers assessed the added predictive value of integrating polygenic risk scores (PRSs) and gut microbiome scores with conventional risk factors for common diseases in a long-term cohort study.

Background

Multiomic technologies are transforming disease prediction by integrating genomic and microbiomic data, offering new insights into age-related conditions like heart disease, diabetes, and cancer. Previously, risk assessments relied mainly on demographic, lifestyle, and clinical metrics. Now, the integration of PRSs and gut microbiome analysis into risk models promises to improve predictive accuracy beyond traditional factors. PRSs provide a cost-effective genetic predisposition metric, while the gut microbiome adds a novel dimension to understanding disease risk. This emerging approach necessitates further research to refine its accuracy and ensure its effectiveness across various populations and healthcare systems.

First Human Patient to Receive a Neuralink Brain Implant Used it to Stay Up All Night Playing Civilization 6

The first human recipient of a Neuralink brain implant has shared new details on his recovery and experience of living with the experimental assistive tech, which has allowed him a greater level of freedom and autonomy, including the ability to pull an all-nighter playing Sid Meier’s Civilization 6.

Neuralink co-founder Elon Musk took to X/Twitter in January to reveal that the company had implanted its first brain-computer interface in the head of a human patient, who was “recovering well” following the surgery. The billionaire also hinted at the time that the implant was functioning well and had detected a “promising neuron spike”. In a subsequent February update, Musk commented that the unnamed patient had seemingly made a full recovery, and was even able to use the implant to manipulate a computer cursor with thought alone.

Finally, on March 20, Neuralink posted its own update to X in the form of a nine-minute livestream in which 29-year-old implant recipient Noland Arbaugh used the technology to play a digital version of chess, while discussing how living with the experimental aide had changed his life.

Researchers Design Foundation AI Models for Use in Pathology

Artificial intelligence is poised to transform the practice of medicine through the design and deployment of AI models that can detect, diagnose, and render prognosis for a disease more rapidly than most human physicians can, and with similar or superior accuracy.

So-called foundation models — trained on vast amounts of unlabeled data and usable in multiple clinical contexts for different purposes with minimal tweaking — offer a particularly tantalizing promise to reshape diagnosis and treatment.

Specific Gut Microbes are Linked to a Lower Risk of Infection

There are trillions of microbes in the human gastrointestinal tract, each of which expresses its own genome, and carries out a variety of biochemical processes. Gut microbes can generate a variety of molecules that can have a significant impact on human health, such as vitamins, specially modified bile acids, and short-chain fatty acids (SCFAs).

SCFAs have fewer than six carbon atoms, and are found in a few major forms, including acetate, propionate, and butyrate. When we eat fibers that are tough to digest, gut microbes metabolize them instead, and generate SCFAs. Many links have been found between butyrate and human health; it is thought to have roles in the maintainence of epithelial barriers, prevention of gut inflammation in the gut and colorectal cancer, and oxidative stress relief.
