Researchers find graphene can strengthen the brain’s neural signals

Published

A recent study from a group of researchers at the International School for Advanced Studies (SISSA) in Italy and the Catalan Institute of Nanoscience and Nanotechnology (ICN2) in Spain have demonstrated how graphene could be combined with neurological tissue, allowing the material to become a valuable tool for medicine and other biological processes.

In a statement to the IEEE Spectrum, Laura Ballerini, a researcher in neurons and nanomaterials at SISSA, stated that the results of the recent study demonstrate that graphene might tune neuronal activities by altering ion mobility at the cell interface depending on the how the single-layer graphene is engineered. According to the researcher, graphene-based nanomaterials have come to represent potential tools in neurology and neurosurgery.

“These materials are increasingly engineered as components of a variety of applications such as biosensors, interfaces, or drug-delivery platforms. In particular, in neural electrode or interfaces, a precise requirement is the stable device/neuronal electrical coupling, which requires governing the interactions between the electrode surface and the cell membrane,” she said.

Graphene has been dubbed as a supermaterial, thanks to its unique set of properties. Graphene, described in simplest terms, is a thin layer of graphite, the same material used in pencil lead. What is particularly remarkable with graphene is that it takes some near-miraculous properties when it is isolated from graphite. At one atom thick, graphene stands as the world’s first two-dimensional material ever discovered. It also boasts a tensile strength of 130 gigapascals, making it ~100 times stronger than steel. Apart from being thin and durable, graphene is also flexible, transparent, seemingly impermeable to most gases and liquids, and most of all, highly conductive.

These properties have allowed graphene to be viewed as a potential game-changer in several fields, including electronics, solar cells, semiconductors, and of course, biomedical technology. Just last year, researchers from the Graphene Flagship developed graphene-based field-effect transistors which have the capability to record brain activity in high resolution while maintaining an optimal level of signal-to-noise ratio (SNR).

Graphene is characterized by its hexagonal atomic structure.

Ballerini noted that thanks to graphene’s electrical properties, transparency, and flexibility, the material has become the ideal material candidate for several ongoing researches. Among these studies, the primary goal has been to analyze and investigate how graphene can tune neuronal excitability, as well as to demonstrate that the material can selectively modify membrane-associated neuronal functions. Ballerini and her team’s latest research, for one, operated under the hypothesis that there would be specific interactions between graphene and potassium ions in the extracellular solution which would regulate cell excitability.

“Graphene properties might (thus) affect neuronal information processing through the physical interactions of such a nanomaterial with the biological environment. Nanomaterials might then represent, in general, unconventional tools to gain insights into genuine biological processes,” Ballerini’s team stated in their conclusion to the recent study.

The applications of graphene are wide, from practical solutions such as water filtration systems and faster internet speeds to measuring brain activity. The material, if any, seems to be tailor-fit for Elon Musk’s neurotechnology startup, Neuralink, which aims to create brain-computer interface systems. Considering that the startup is aimed at developing neural lace technologies, advances in graphene, showcased in these recent studies, could very well help make Musk’s vision of “wizard hats for the brain” a reality.

Tesla’s sales in the United Kingdom rose in June, climbing 14% year-over-year to 7,719 units, as per data from the Society of Motor Manufacturers and Traders (SMMT). The spike in the company’s sales coincided with the first deliveries of the updated Model Y last month.

Model Y deliveries support Tesla’s UK recovery

Tesla’s June performance marked one of its strongest months in the UK so far this year, with new Model Y deliveries contributing significantly to the company’s momentum. 

While the SMMT listed Tesla with 7,719 deliveries in June, independent data from New AutoMotive suggested that the electric vehicle maker registered 7,891 units during the month instead. However, year-to-date figures for Tesla remain 2% down compared to 2024, as per a report from Reuters.

While Tesla made a strong showing in June, rivals are also growing. Chinese automaker BYD saw UK sales rise nearly fourfold to 2,498 units, while Ford posted the highest EV growth among major automakers, with a more than fourfold increase in the first half of 2025.

Overall, the UK’s battery electric vehicle (BEV) demand surged 39% to to 47,354 units last month, helping push total new car sales in the UK to 191,316 units, up 6.7% from the same period in 2024.

EV adoption accelerates, but concerns linger

June marked the best month for UK car sales since 2019, though the SMMT cautioned that growth in the electric vehicle sector remains heavily dependent on discounting and support programs. Still, one in four new vehicle buyers in June chose a battery electric vehicle.

SMMT Chief Executive Mike Hawes noted that despite strong BEV demand, sales levels are still below regulatory targets. “Further growth in sales, and the sector will rely on increased and improved charging facilities to boost mainstream electric vehicle adoption,” Hawes stated.

Also taking effect this week was a new US-UK trade deal, which lowers tariffs on UK car exports to the United States from 27.5% to 10%. The agreement could benefit UK-based EV producers aiming to expand across the country.

Tesla Model 3 ranks as the safest new car in Europe for 2025, per Euro NCAP tests

Despite being on the market longer than many of its rivals, the Tesla Model 3 continues to set the bar for vehicle safety.

The Tesla Model 3 has been named the safest new car on sale in 2025, according to the latest results from the Euro NCAP. Among 20 newly tested vehicles, the Model 3 emerged at the top of the list, scoring an impressive 359 out of 400 possible points across all major safety categories.

Tesla Model 3’s safety systems

Despite being on the market longer than many of its rivals, the Tesla Model 3 continues to set the bar for vehicle safety. Under Euro NCAP’s stricter 2025 testing protocols, the electric sedan earned 90% for adult occupant protection, 93% for child occupant protection, 89% for pedestrian protection, and 87% for its Safety Assist systems.

The updated Model 3 received particular praise for its advanced driver assistance features, including Tesla’s autonomous emergency braking (AEB) system, which performed well across various test scenarios. Its Intelligent Speed Assistance and child presence detection system were cited as noteworthy features as well, as per a WhatCar report.

Other notable safety features include the Model 3’s pedestrian-friendly pop-up hood and robust crash protection for both front and side collisions. Euro NCAP also highlighted the Model 3’s ability to detect vulnerable road users during complex maneuvers, such as turning across oncoming traffic.

Euro NCAP’s Autopilot caution

While the Model 3’s safety scores were impressive across the board, Euro NCAP did raise concerns about driver expectations of Tesla’s Autopilot system. The organization warned that some owners may overestimate the system’s capabilities, potentially leading to misuse or inattention behind the wheel. Even so, the Model 3 remained the highest-scoring vehicle tested under Euro NCAP’s updated criteria this year.

The Euro NCAP’s concerns are also quite interesting because Tesla’s Full Self-Driving (FSD) Supervised, which is arguably the company’s most robust safety suite, is not allowed for public rollout in Europe yet. FSD Supervised would allow the Model 3 to navigate inner city streets with only minimal human supervision.

Other top scorers included the Volkswagen ID.7, Polestar 3, and Geely EX5, but none matched the Model 3’s total score or consistency across categories. A total of 14 out of 20 newly tested cars earned five stars, while several models, including the Kia EV3, MG ZS, and Renault 5, fell short of the top rating.

Why Tesla’s Q3 could be one of its biggest quarters in history

Tesla could stand to benefit from the removal of the $7,500 EV tax credit at the end of Q3.

Tesla has gotten off to a slow start in 2025, as the first half of the year has not been one to remember from a delivery perspective.

However, Q3 could end up being one of the best the company has had in history, with the United States potentially being a major contributor to what might reverse a slow start to the year.

Earlier today, the United States’ House of Representatives officially passed President Trump’s “Big Beautiful Bill,” after it made its way through the Senate earlier this week. The bill will head to President Trump, as he looks to sign it before his July 4 deadline.

The Bill will effectively bring closure to the $7,500 EV tax credit, which will end on September 30, 2025. This means, over the next three months in the United States, those who are looking to buy an EV will have their last chance to take advantage of the credit. EVs will then be, for most people, $7,500 more expensive, in essence.

The tax credit is available to any single filer who makes under $150,000 per year, $225,000 a year to a head of household, and $300,000 to couples filing jointly.

Ending the tax credit was expected with the Trump administration, as his policies have leaned significantly toward reliance on fossil fuels, ending what he calls an “EV mandate.” He has used this phrase several times in disagreements with Tesla CEO Elon Musk.

Nevertheless, those who have been on the fence about buying a Tesla, or any EV, for that matter, will have some decisions to make in the next three months. While all companies will stand to benefit from this time crunch, Tesla could be the true winner because of its sheer volume.

If things are done correctly, meaning if Tesla can also offer incentives like 0% APR, special pricing on leasing or financing, or other advantages (like free Red, White, and Blue for a short period of time in celebration of Independence Day), it could see some real volume in sales this quarter.

Tesla is just a shade under 721,000 deliveries for the year, so it’s on pace for roughly 1.4 million for 2025. This would be a decrease from the 1.8 million cars it delivered in each of the last two years. Traditionally, the second half of the year has produced Tesla’s strongest quarters. Its top three quarters in terms of deliveries are Q4 2024 with 495,570 vehicles, Q4 2023 with 484,507 vehicles, and Q3 2024 with 462,890 vehicles.
