As the electric vehicle market booms, the demand for lithium—the mineral required for lithium-ion batteries—has also soared. Global lithium production has more than tripled in the last decade. But current methods of extracting lithium from rock ores or brines are slow and come with high energy demands and environmental costs. They also require sources of lithium which are incredibly concentrated to begin with and are only found in a few countries.
A research team in China has initiated and successfully developed a jet origin identification technology which can significantly enhance the scientific discovery capabilities of high-energy collider experiments.
Russian organizations are at the receiving end of cyber attacks that have been found to deliver a Windows version of a malware called Decoy Dog.
Cybersecurity company Positive Technologies is tracking the activity cluster under the name Operation Lahat, attributing it to an advanced persistent threat (APT) group called HellHounds.
“The Hellhounds group compromises organizations they select and gain a foothold on their networks, remaining undetected for years,” security researchers Aleksandr Grigorian and Stanislav Pyzhov said. “In doing so, the group leverages primary compromise vectors, from vulnerable web services to trusted relationships.”
Experts from Germany believe their most recent breakthrough advances the quality of solid-state, sodium-ion batteries.
It’s technology that many researchers are pursuing as a replacement for common lithium-ion power packs, with the hope of finding a better-performing and cheaper alternative.
The latest news from the labs at Karlsruhe Institute of Technology includes an update about a highly conductive battery with “dramatically” enhanced performance at room temperature, according to a story from TechXplore.
Optical waves propagating through air or multi-mode fiber can be patterned or decomposed using orthogonal spatial modes, with far-ranging applications in imaging, communication, and directed energy. Yet the systems that perform these wavefront manipulations are cumbersome and large, restricting their utilization to high-end applications.
An Israeli startup has developed a way to make lead acid batteries last four times longer, disrupting a multi-billion-dollar industry and potentially making them the rechargeable – and recyclable – energy storage method of choice around the world.
Lead acid is the second most common battery technology worldwide and the power cells are currently used as the starter batteries in cars, trucks and motorcycles.
The batteries have a positive plate made of lead dioxide on one end, and a spongy lead negative plate on the other end, with sulfuric acid flowing between them both to conduct the electricity.
Converting CO2 into fuel and chemicals using electricity, also known as electrochemical conversion of CO2, is a promising way to reduce emissions. This process allows us to use carbon captured from industries and the atmosphere and turn it into resources that we usually get from fossil fuels.

A previously undocumented cyber espionage-focused threat actor named LilacSquid has been linked to targeted attacks spanning various sectors in the United States (U.S.), Europe, and Asia as part of a data theft campaign since at least 2021.
“The campaign is geared toward establishing long-term access to compromised victim organizations to enable LilacSquid to siphon data of interest to attacker-controlled servers,” Cisco Talos researcher Asheer Malhotra said in a new technical report published today.
Targets include information technology organizations building software for the research and industrial sectors in the U.S, energy companies in Europe, and the pharmaceutical sector in Asia, indicating a broad victimology footprint.
Blue energy has the potential to provide a sustainable alternative to fossil fuels. In simple terms, it involves harnessing the energy produced when the ions in a salt solution move from high to low concentrations.
