Researchers find graphene can strengthen the brain’s neural signals
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).
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.

Nikola Motor founder Trevor Milton given full pardon by President Trump

Nikola Motor founder Trevor Milton has been given a full pardon by U.S. President Donald Trump in an unprecedented turn of events.
Trevor Milton Media announced late Thursday that the formerly jailed founder of the all-electric automaker that President Trump had “pledged to end the political weaponization of the Justice Department. This pardon marks a step toward fulfilling that commitment.”
Milton was sentenced to four years in prison in December 2023 after being found guilty of multiple counts of fraud.
Nikola founder Trevor Milton sentenced to four years in prison
“I was not a very seasoned CEO,” Milton said after his sentencing. Questions about the legitimacy of some Nikola product demonstrations and several statements that were found to be misleading regarding the company’s progress on its vehicles brought Milton to U.S. Federal Court to face two counts of wire fraud and one count of securities fraud.
Now, he is free.
Milton said in a statement:
“This pardon is not just about me—it’s about every American who has been railroaded by the government, and unfortunately, that’s a lot of people. It is no wonder why trust and confidence in the Justice Department has eroded to nothing. I wish judges would stop believing whatever the prosecutors feed them so Americans could trust the justice system again. Until that happens, our justice system will continue to erode until there is nothing left. The 90+% conviction rate in New York is appalling and is a result of prosecutors getting whatever they want and putting innocent people in prison. I saw firsthand the tactics they use to achieve those guaranteed convictions. I am incredibly grateful to President Trump for his courage in standing up for what is right and for granting me this sacred pardon of innocence.”
Milton will now launch a documentary that is available for preview here.

Tesla vandal who lit Las Vegas repair center on fire arrested

A vandal in Las Vegas who lit a Tesla repair center on fire has been arrested, bringing a name and face to the crime that engulfed vehicles and a structure in flames.
Officers in Las Vegas arrested Paul Kim, a 36-year-old, on Wednesday. He faces charges of arson and possessing an explosive device.
The Tesla repair center at 6260 West Badura Avenue was set aflame on March 18 at around 2:45 a.m. In total, five vehicles were set on fire, as well as the building itself. It was one of the more notable instances of vandalism against Tesla in recent months, but police now have their culprit.
Las Vegas Metro Police Department Sheriff Dori Koren described the weapons Kim used to execute the attack:
“He used what appeared to be multiple Molotov cocktails and firearms to conduct his attack.”
As the instances of attacks on Tesla continue to be publicized, we are now seeing considerable pushback from owners, the company, and even the United States government regarding what it calls “domestic terrorism.”
Owners are now filing lawsuits against those who vandalize their vehicles, as the first civil suit against a vandal was filed in Texas yesterday.
Great

Tesla has not made any moves itself against the vandals, but we expect the company to potentially enter some litigation against groups or politicians that incite violence against its property and the owners of its vehicles.
Additionally, the U.S. government has utilized the FBI to probe incidents against Tesla as a part of them being constituted as instances of domestic terrorism. Earlier this month, the Bureau established a specific task force to handle Tesla-related attacks.
“The FBI has been investigating the increase in violent activity toward Tesla, and over the last few days, we have taken additional steps to crack down and coordinate our response,” FBI head Kash Patel said on X. “This is domestic terrorism. Those responsible will be pursued, caught, and brought to justice.”

Elon Musk clarifies Trump tariff effect on Tesla: “The cost impact is not trivial”
The U.S. President has stated that Elon Musk stayed silent and provided no input in the administration’s tariffs.

U.S. President Donald Trump’s plan to implement a 25% tariff on non-U.S.-made vehicles starting next week would affect American electric car maker Tesla.
This was confirmed by CEO Elon Musk in a recent post on social media platform X.
Musk and Trump
While Elon Musk works closely with the Trump administration due to his role in the Department of Government Efficiency (DOGE), the U.S. president has emphasized that the Tesla CEO never asks for favors. This was highlighted in his recent comments, when he stated that Elon Musk stayed silent and provided no input in the administration’s 25% auto tariffs.
When asked by reporters if the new tariffs would be good for Tesla, Trump noted that they may be “net neutral or they may be good.” The U.S. president also pointed to Tesla’s automotive plants in Fremont, California and Austin, Texas, which produce vehicles that are sold in the country. “Anybody that has plants in the United States — it’s going to be good for them,” Trump noted.
Tesla Affected
In a post on X, Elon Musk clarified that the Trump administration’s tariffs would affect the prices of vehicle parts that are sourced from other countries. This was a concern that Tesla previously outlined in a letter to the U.S. Trade Representative, which noted that even with “aggressive localization” of its supply chain, “certain parts and components are difficult or impossible to source within the United States.”
As per Musk in his recent post on X, the cost impact of the Trump administration’s tariffs is no joke. “To be clear, this will affect the price of parts in Tesla cars that come from other countries. The cost impact is not trivial,” Musk wrote in his post.
Potential Effects
Reactions to Musk’s comments from users of the social media platform were varied, with some speculating that the Trump auto tariffs could result in Teslas becoming more expensive in the United States. Despite this, the potential increases in Tesla’s vehicle prices might not be as notable as other cars, particularly those that are produced outside the country.
