This system charges without external fields, advancing energy technology.
A research team at the University of Genova has developed the spin quantum battery, an energy storage system that uses the spin degrees of freedom of particles.

We are getting smarter as we engage in prompt engineering, but we are also still defining intelligence.
An ancient rock — or rather, the living microbes inside of it — could offer an unprecedented glimpse into early life on Earth.
Leading by example is a core belief. I’ve always advocated for a leadership approach that empowers the team and fosters a culture of continuous learning. The focus on sustainability isn’t just about technology—it’s about cultivating an environment where innovation thrives and where every team member is aligned with the vision of creating a more energy-efficient future.
Operating on three core principles (empowerment, communication and accountability) drives success and ensures every decision made is in line with long-term goals of sustainability and growth. Empowering the team means trusting them to innovate and make decisions that move the company forward, while open communication ensures alignment as the organization scales.
Looking ahead, the future of data centers lies in sustainability and transparency. As the demand for computing power grows, so too will the need for solutions that minimize environmental impact.
What would happen day by day if aliens made contact with earth, according to ex-NASA expert.
It’s a moment that’s been depicted countless times in science fiction — but what would actually happen when extraterrestrials make contact via a signal picked up on Earth?
The moment could come as early as the end of this decade: if aliens receive signals sent by NASA’s Deep Space Network (DSN) to the Pioneer 10 satellite in the 70s, for example.

The sun’s magnetic activity causes auroras, and the relationship between solar flares and auroras reveals an 11-year cycle; we’re experiencing a particularly busy one right now.
A small team of physicists at the University of Amsterdam has demonstrated the ability of 3D-printed particles to propel themselves across the surface of a fluid, given the right fuel. The group has posted a paper describing their particles on the arXiv preprint server.
Prior research has shown that droplets with a surface tension lower than the surface tension of surrounding fluid will spread rather than mixing, a phenomenon known as the Marangoni effect. A drop of alcohol in a cup of water, for example, will spread across the surface rather than mix with the water and it remains until it evaporates. In this new effort, the research team used this effect to create self-propelling particles.
The particles were 3D printed into a shape like a hockey puck—each was approximately 1 centimeter in diameter. The particles were hollow, making them buoyant. The researchers described the hollow part of the puck as a fuel tank into which they poured a small amount of alcohol. They also poked a tiny pinhole in the puck to allow the alcohol to slowly escape when it was placed in a cup of water. Due to the Marangoni effect, the alcohol tried to spread, carrying the puck along with it.
“This work shows that sensitive information can be leaked in ways that previously haven’t been considered,” said Poorya Mollahosseini, a graduate student at Princeton and the paper’s co-lead author with Sayed Saad Afzal, a graduate student at MIT.
How are underwater communications protected?
The security of underwater communications relies heavily on the inability of sound traveling underwater to penetrate the surface, the researchers said. Signals that carry information are transmitted underwater as sound waves. Because water and air have very different densities, the water’s surface acts as a barrier for sound. When underwater sound waves hit the surface, they mostly just bounce off.
Hackers misuse Godot Engine in the GodLoader campaign, infecting 17,000+ systems undetected via GitHub.
“The effects of cyber-enabled crime can be devastating – people losing their life savings, businesses crippled, and trust in digital and financial systems undermined,” INTERPOL Secretary General Valdecy Urquiza said in a statement.
“The borderless nature of cybercrime means international police cooperation is essential, and the success of this operation supported by INTERPOL shows what results can be achieved when countries work together. It’s only through united efforts that we can make the real and digital worlds safer.”
As part of HAECHI-V, INTERPOL said Korean and Beijing authorities jointly dismantled a widespread voice phishing syndicate responsible for financial losses totaling $1.1 billion and affecting over 1,900 victims.
