The Nano Materials Research Division at the Korea Institute of Materials Science (KIMS), led by Dr. Tae-Hoon Kim and Dr. Jung-Goo Lee has successfully developed a grain boundary diffusion process that enables the fabrication of high-performance permanent magnets without the use of expensive heavy rare earth elements. This pioneering technology marks the world’s first achievement in this field.

The findings are published in Acta Materialia.

Permanent magnets are key components in various high-value-added products, including electric vehicle (EV) motors and robots. However, conventional permanent magnet manufacturing processes have been heavily dependent on heavy rare earth elements, which are exclusively produced by China, leading to high resource dependency and .

In a megascience-scale collaboration with French researchers from College de France and the University of Montpellier, Skoltech scientists have shown a much-publicized problem with next-generation lithium-ion batteries to have been induced by the very experiments that sought to investigate it. Published in Nature Materials, the team’s findings suggest that the issue of lithium-rich cathode material deterioration should be approached from a different angle, giving hope for more efficient lithium-ion batteries that would store some 30% more energy.

Efficient energy storage is critical for the transition to a low-carbon economy, whether in grid-scale applications, electric vehicles, or portable devices. Lithium-ion batteries remain the best-developed electrochemical storage technology and promise further improvements. In particular, next-generation batteries with so-called lithium-rich cathodes could store about one-third more energy than their state-of-the-art counterparts with cathodes made of lithium nickel manganese cobalt oxide, or NMC.

A key challenge hindering the commercialization of lithium-rich batteries is voltage fade and capacity drop. As the battery is repeatedly charged and discharged in the course of normal use, its cathode material undergoes degradation of unclear nature, causing gradual voltage and capacity loss. The problem is known to be associated with the reduction and oxidation of the in NMC, but the precise nature of this redox process is not understood. This theoretical gap undermines the attempts to overcome voltage fade and bring next-generation batteries to the market.

Fueling excitement, Tesla’s Cybercab was spotted navigating the expansive grounds of Gigafactory Texas autonomously. Tesla Cybercab, also labeled as the Robotaxi, was unveiled by CEO Elon Musk in October 2024, during the ‘We Robot’ event in California. The two-seat vehicle has no steering wheel or pedals – it represents Tesla’s end goal for a completely autonomous transportation network.

The Cybercab has butterfly doors that open automatically, a hatchback layout for the cargo room, and an inductive charging technique that eliminates the need for conventional charging ports. Tesla expects to start production of the Cybercabs before 2027, and the price is estimated at $30,000.

The Tesla CyberCab is an autonomous vehicle that Tesla plans to use in its upcoming ride-hailing system. The CyberCab represents its distinct vehicle type because it is specially designed without any human driver functionalities for enhanced efficiency combined with premium passenger comfort and an extended product life span.

A team of researchers led by Colorado State University graduate student Luke Wernert and Associate Professor Hua Chen has discovered a new kind of Hall effect that could enable more energy-efficient electronic devices.

Their findings, published in Physical Review Letters in collaboration with graduate student Bastián Pradenas and Professor Oleg Tchernyshyov at Johns Hopkins University, reveal a previously unknown Hall mass in complex magnets called noncollinear antiferromagnets.

The Hall effect—first discovered by Edwin Hall at Johns Hopkins in 1879—usually refers to electric current flowing sideways when exposed to an external magnetic field, creating a measurable voltage. This sideways flow underpins everything from vehicle speed sensors to phone motion detectors. But in the CSU team’s work, electrons’ spin (a tiny, intrinsic form of angular momentum) takes center stage instead of .

Demand for lithium is rising due to its use in batteries for mobile devices, cars and clean energy storage. Securing access to natural deposits of the mineral is now a matter of strategic importance, but lithium can be found elsewhere in nature.

As an alternative to mining, Imperial researchers have created a technology that could be used to efficiently extract it from saltwater sources such as salt-lake brines or geothermal brine solutions.

Conventional extraction from brines takes months and uses significant amounts of water and chemicals, generating greenhouse gas emissions in the process. The alternative developed by Dr. Qilei Song and his team in the Department of Chemical Engineering uses a membrane that separates lithium from by filtering it through tiny pores.

Nickel’s role in the future of electric vehicle batteries is clear: It’s more abundant and easier to obtain than widely used cobalt, and its higher energy density means longer driving distances between charges.

However, nickel is less stable than other materials with respect to cycle life, , and safety. Researchers from the University of Texas at Austin and Argonne National Laboratory aim to change that with a new study that dives deeply into nickel-based cathodes, one of the two electrodes that facilitate in batteries.

“High-nickel cathodes have the potential to revolutionize the EV market by providing longer driving ranges,” said Arumugam Manthiram, a professor at the Walker Department of Mechanical Engineering and Texas Materials Institute and one of the leaders of the study published in Nature Energy.

Like engineers who design high-performance Formula One race cars, scientists want to create high-performance plasmas in twisty fusion systems known as stellarators. Achieving this performance means that the plasma must retain much of its heat and stay within its confining magnetic fields.

To ease the creation of these plasmas, physicists have created a new computer code that could speed up the design of the complicated magnets that shape the plasma, making stellarators simpler and more affordable to build.

Known as QUADCOIL, the code helps scientists rule out plasma shapes that are stable but require magnets with overly complicated shapes. With this information, scientists can instead devote their efforts to designing stellarators that can be built affordably.

This is some wild stuff o.o. As much is unknown about this universe I still think this phenomenon is more exterrestial possibly even from the grand architect like god or some alien species that is either moving a black hole spaceship or some sorta wormhole expansion for alien transportation or could be even god due its nature as his vehicle the Ezekiel wheel was spotted near Venus in 2020. Still is an unknown threat whether it is an actual threat is still unknown. If it is a threat theoretically we could evaporate the black hole though but this would require large amounts of energy maybe even Higgs bosons somehow.

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes.

The star cluster in question is called Palomar 5. It’s a stellar stream that stretches out across 30,000 light-years, and is located around 80,000 light-years away.

Such globular clusters are often considered ‘fossils’ of the early Universe. They’re very dense and spherical, typically containing roughly 100,000 to 1 million very old stars; some, like NGC 6397, are nearly as old as the Universe itself.
