Verifying asset owners in world of AI deep fakes
Today, it's not easy to verify online that the person you are interacting with is that person because of the prevalence of AI deepfakes and sophisticated cybercriminals, according to Christina Hulka, executive director of the Secure Technology Alliance, an organization focused on identity, access and payments. As a result, having a unified verification system would be useful because there would be cryptographic validation that people are who they say they are.
"The [financial services] industry is focused on how to build a zero-trust framework for identification. You don't trust anything until it's verified," Hulka said. "The challenge is getting everyone together about which technology to use that makes it as simple and as seamless for the consumer as possible," she added.
It's hard to say precisely how a broad-based digital verification system would work but to support a fully tokenized financial structure, a system would, at a minimum, need to meet stringent security requirements, particularly those tied to financial regulations like the Know Your Customer rule and anti-money laundering rules, according to Zulfikar Ramzan, chief technology officer at Point Wild, a cybersecurity company.
At the same time, the system would need to be low friction and quick. There's no shortage of technical tools today, especially from the field of cryptography, that can effectively bind a digital identity to a transaction, Ramzan said. "Fifteen to 20 years ago, this conversation would have been a non-starter," he added.
It is clear from Fink's decision to give this issue prominent placement in his annual letter — even if it came in third in the order of issues he covered behind both the politics of protectionism and the growing role of private markets — that he isn't letting up. And what's needed to make this a reality, he contends, is a new digital identity verification system. The letter is short on details, and BlackRock declined to elaborate, but, at least on the surface, the solution for Fink is clear. "If we're serious about building an efficient and accessible financial system, championing tokenization alone won't suffice. We must solve digital verification, too," he wrote.
Improving lithium ion using nanotechnology
Lithium-ion batteries have become the workhorses of modern energy storage, powering everything from smartphones and laptops to electric vehicles and renewable energy grids. However, the push for better performance, higher energy density, faster charging, and longer lifespan continues to drive global research and innovation.
What sets this new material apart is its unique structure, which is rich in grain boundaries that enhance charge storage and transport. The researchers employed a meticulous layer-by-layer self-assembly process using polystyrene (PS) beads as templates.
These beads were first coated with graphene oxide and NiFe-LDH precursors. Once the templates were removed, a thermal treatment transformed the nickel-iron layers into nanocrystalline nickel-iron oxide (NiFe₂O₄) and amorphous nickel oxide (a-NiO) while also reducing the GO into conductive rGO.

Exploring Power Sports Batteries: A Comprehensive Guide
When it comes to choosing the right battery for your power sports vehicles, there has been a significant evolution in battery technology over the years. In a recent video, John Talley from Partzilla.com revisits an important topic for any power sports enthusiast: understanding different types of batteries and chargers available in the market today.
A Brief History of Batteries
Part 2/8:
Five years ago, the battery landscape primarily revolved around lead acid, AGM (Absorbed Glass Mat), and sealed AGM batteries. With the advancement of technology, lithium-ion batteries have joined the mix. The video outlines the characteristics of these batteries, guiding viewers through a decision-making process regarding whether the shift to lithium is right for them.
Lead Acid Batteries
To start, Talley provides an overview of lead acid batteries. These consist of plates within an electrolyte solution made of sulfuric acid, generating about 2 volts per cell. A typical 12V lead acid battery contains six such cells.
Advantages and Disadvantages
Part 3/8:
The advantages of lead acid batteries include their ability to deliver high surge currents, making them particularly useful in automotive and marine applications. However, they come with significant downsides. Maintenance is crucial; one must regularly check the electrolyte levels and add distilled water to maintain battery life. Failing to do so can lead to extensive damage.
In contrast, their cost-effectiveness and ability to withstand various environmental conditions make them a popular choice for work-related settings.
The Rise of AGM Batteries
Part 4/8:
Next, Talley transitions to AGM batteries, which address many of the maintenance issues surrounding conventional lead acid batteries. AGM batteries utilize fiberglass mats to absorb the electrolyte, allowing for a maintenance-free design.
Performance Insights
AGM batteries are designed to be more resilient, providing better performance, longer lifespans, and the ability to survive harsh conditions and vibrations. This makes them ideal for power sports, especially in rugged applications such as ATVs and side-by-sides.
While lead acid batteries are cheaper, AGM batteries excel in durability and efficiency—applicable in both recreational and professional settings.
The Innovative Lithium-Ion Battery
Part 5/8:
Transitioning into the realm of lithium-ion batteries, Talley sheds light on what makes these modern batteries unique. Known for their high energy density, lightweight nature, and long life cycles, lithium-ion batteries have revolutionized the portable power landscape.
Key Features
The lithium-ion battery consists of a graphite anode and a lithium-based cathode, operating within a sealed environment. The efficient transfer of lithium ions during charging and discharging allows for increased power storage capability.
One standout feature of lithium-ion batteries is their ability to charge quickly—often two to three times faster than AGM or lead acid alternatives. Furthermore, they do not suffer from memory effects, allowing users to charge them without fully depleting them first.
Part 6/8:
Despite the numerous advantages, lithium-ion batteries are notably more expensive and require specialized chargers. Talley emphasizes the importance of using the right charger to prevent damage to the battery.
Considerations for Charging
In discussing chargers, Talley explains that not all chargers are created equal. While smaller chargers can be used for maintenance, they often lack the capacity to effectively restore a depleted lithium-ion battery. Larger and more advanced chargers capable of handling various battery types are essential for optimal performance.
Recommendations for Usage
Part 7/8:
Talley advises paying close attention to charger specifications, particularly voltage outputs. For lithium-ion batteries, a charger should typically output between 13.6 and 14.6 volts for proper functionality. If dealing with older power sports vehicles, an upgrade to the charging system may be necessary for compatibility.
Conclusion
To wrap up the discussion, Talley encourages those seeking batteries, chargers, or tools for power sports to check out Partzilla.com for their needs. He also invites viewers to leave any questions or comments to facilitate further discussion.
Part 8/8:
Investing time into understanding the different battery types—lead acid, AGM, and lithium-ion—provides valuable insight, helping power sports enthusiasts make informed decisions tailored to their specific needs. Whether one prioritizes cost, weight, or performance, careful consideration will ensure the right choice in powering a thrilling ride.
The result is a hollow, sphere-like structure where the active materials are well-integrated and protected, offering high conductivity and degradation resistance.
According to the research team, advanced imaging and analytical techniques, including X-ray diffraction and transmission electron microscopy, confirmed the structure and composition of the material. Moreover, electrochemical testing revealed impressive results: the new anode delivered a high specific capacity of 1687.6 mA h g⁻¹ at 100 mA g⁻¹, even after 580 charge/discharge cycles.
“We believe the future of energy storage lies not just in improving single materials but in developing systems of interacting materials that produce synergistic effects. This research shows a clear path toward smaller, lighter, and more efficient batteries,” he added.
The team’s work could lead to commercial battery technologies that deliver longer life, faster charging, and improved performance in everything from electric vehicles to grid-scale storage, potentially within the next five to ten years. As the global demand for cleaner, more efficient energy grows, innovations like this offer a promising glimpse into what’s possible.

Tokenization of the market, from stocks to bonds to real estate is coming, says BlackRock CEO Larry Fink, if we can solve one problem
BlackRock CEO Larry Fink thinks tokenization of stock and bond markets will revolutionize financial ownership and investing, but there's a security challenge.
If the vision of Larry Fink — CEO of BlackRock, the world's biggest money manager — becomes reality, all assets from stocks to bonds to real estate and more would be tradable online, on a blockchain.
"Every asset — can be tokenized," Fink wrote in his recent annual letter to investors.
Unlike traditional paper certificates signifying financial ownership, tokens live securely on a blockchain, enabling instant buying, selling, and transfers without paperwork or waiting — "much like a digital deed," he wrote.
Fink says it would be nothing short of a "revolution" for investing. Think 24-hour markets and a trading settlement process that can be compacted down into seconds from a process that today can still take days, with billions of dollars reinvested immediately back into the economy.
But there's one big problem, one technology challenge that stands in the way: the lack of a coordinated digital identity verification system.
While technology experts say Fink's idea isn't improbable, they agree that there are cybersecurity challenges ahead in making it work.

Preços na Amazon podem subir após impacto das tarifas de Trump, alerta CEO
Os aumentos devem afetar principalmente os vendedores terceirizados, que representam o maior volume de vendas da Amazon.
#technology #amazon #policy
Os preços de produtos vendidos na Amazon podem aumentar, por causa do tarifaço de Donald Trump anunciado no início de abril, impactando a economia mundial.
De acordo com o executivo, a empresa está digerindo as mudanças nos custos provocadas pela guerra tarifária e seguirá tentando manter os valores praticados.
Porém, ele acredita que os vendedores terceirizados provavelmente não conseguirão fazer o mesmo e acabarão repassando os custos para os consumidores em algum momento.
“Eu entendo por que, quero dizer, dependendo do país em que você está, você não tem 50% de margem extra com a qual possa jogar. Acho que eles vão tentar repassar o custo”,
previu Jassy durante entrevista à CNBC, se referindo aos impactos das tarifas de Trump.
Respondendo por cerca de 60% do volume de vendas da Amazon, o mercado de vendedores terceirizados é composto por milhões de pessoas que utilizam os serviços da plataforma para alcançar clientes em todo o mundo.
Grande parte delas é da China ou compra seus produtos por lá, país que recebeu a maior tarifa aplicada pela Casa Branca e apostou em retaliações.

Google implementa IA para acelerar conexões na maior rede elétrica dos EUA
A demanda por eletricidade tem aumentado à medida que grandes empresas de tecnologia constroem mais data centers para treinar e implementar IA
#technology
O Google, da Alphabet, está fazendo uma parceria com a maior operadora de rede elétrica da América do Norte, a PJM Interconnection, para implementar tecnologias de inteligência artificial.
A colaboração representa a primeira aplicação da tecnologia na gestão de filas de interconexão. A demanda por eletricidade tem aumentado à medida que grandes empresas de tecnologia constroem mais data centers para treinar e implementar IA.
“O setor vem falando sobre construir redes elétricas mais inteligentes há mais de uma década, e agora, com a IA, temos uma oportunidade real de transformar a discussão em ação”, disse Amanda Peterson Corio.
Nos últimos anos, o tempo de espera para conectar novas fontes de eletricidade — como eólica, solar e gás natural — às redes elétricas dos EUA subiu a níveis históricos.
O Google, em parceria com a Tapestry, empresa apoiada pela Alphabet, afirma que pode ajudar a eliminar ao menos parte dessa espera usando IA para sintetizar informações e automatizar partes do processo de análise.
A PJM controla o sistema elétrico que atende 67 milhões de pessoas nos EUA, incluindo o norte da Virgínia, o maior polo de data centers do mundo.
