Published Efficient biohybrid batteries



Formic acid, which can be produced electrochemically from carbon dioxide, is a promising energy carrier. A research team has now developed a fast-charging hybrid battery system that combines the electrochemical generation of formic acid as an energy carrier with a microbial fuel cell. This novel, fast-charging biohybrid battery system can be used to monitor the toxicity of drinking water, just one of many potential future applications.
Published New battery technology could lead to safer, high-energy electric vehicles



Researchers studying how lithium batteries fail have developed a new technology that could enable next-generation electric vehicles (EVs) and other devices that are less prone to battery fires while increasing energy storage.
Published Cathode active materials for lithium-ion batteries could be produced at low temperatures



Layered lithium cobalt oxide, a key component of lithium-ion batteries, has been synthesized at temperatures as low as 300°C and durations as short as 30 minutes.
Published A step on the way to solid-state batteries



A lithium ceramic could act as a solid electrolyte in a more powerful and cost-efficient generation of rechargeable lithium-ion batteries. The challenge is to find a production method that works without sintering at high temperatures. A research team has now introduced a sinter-free method for the efficient, low-temperature synthesis of these ceramics in a conductive crystalline form.
Published Holy bat skull! Fossil adds vital piece to bat evolution puzzle



Bats may have lived in caves and used soundwaves to navigate much earlier than first thought.
Published A miniature magnetic resonance imager made of diamond



The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research team has now developed diamond quantum sensors which can be used to improve resolution in magnetic imaging.
Published Cobalt-free battery for cleaner, greener power



High-capacity and reliable rechargeable batteries are a critical component of many devices and even modes of transport. They play a key role in the shift to a greener world. A wide variety of elements are used in their production, including cobalt, the production of which contributes to some environmental, economic, and social issues. A team now presents a viable alternative to cobalt which in some ways can outperform state-of-the-art battery chemistry. It also survives a large number of recharge cycles, and the underlying theory can be applied to other problems.
Published Researchers unveil fire-inhibiting nonflammable gel polymer electrolyte for lithium-ion batteries



A research team has succeeded in developing a non-flammable gel polymer electrolyte (GPE) that is set to revolutionize the safety of lithium-ion batteries (LIBs) by mitigating the risks of thermal runaway and fire incidents.
Published New recipe for efficient, environmentally friendly battery recycling



Researchers are now presenting a new and efficient way to recycle metals from spent electric car batteries. The method allows recovery of 100 per cent of the aluminum and 98 per cent of the lithium in electric car batteries. At the same time, the loss of valuable raw materials such as nickel, cobalt and manganese is minimized. No expensive or harmful chemicals are required in the process because the researchers use oxalic acid -- an organic acid that can be found in the plant kingdom.
Published Extraordinary fossil find reveals details about the weight and diet of extinct saber-toothed marsupial



A 13-million-year-old saber-toothed marsupial skeleton discovered during paleontological explorations in Colombia is the most complete specimen recovered in the region.
Published Revolutionizing energy storage: Metal nanoclusters for stable lithium--sulfur batteries



Lithium–sulfur batteries (LSBs) offer a higher energy storage potential. However, issues like formation of lithium polysulfides and lithium dendrites lead to capacity loss and raise safety concerns. Now, researchers have developed a graphene separator embedded with platinum-doped gold nanoclusters, which enhance lithium-ion transport and facilitate redox reactions. This breakthrough addresses the long-standing issues associated with LSBs, setting the stage for their commercialization.
Published Race to find world's oldest mammal fossils led to mud-slinging



The hunt for the world’s most ancient mammals descended into academic warfare in the seventies, researchers have discovered.
Published Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought



For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.
Published Genome study reveals 30 years of Darwin's finch evolution



An international team of researchers has released a landmark study on contemporary evolutionary change in natural populations. Their study uses one of the largest genomic datasets ever produced for animals in their natural environment, comprising nearly 4,000 Darwin's finches. The study has revealed the genetic basis of adaptation in this iconic group.
Published Ball milling provides high pressure benefits to battery materials



Cheaper, more efficient lithium-ion batteries could be produced by harnessing previously overlooked high pressures generated during the manufacturing process.
Published Unlocking the potential of silicon anode materials for commercialized batteries



A research team presented an analysis protocol to evaluate silicon cathode materials applicable to commercialized batteries.
Published Novel battery technology with negligible voltage decay



A pivotal breakthrough in battery technology that has profound implications for our energy future has been achieved.
Published A new twist on rechargeable battery performance



Rechargeable battery performance could be improved by a new understanding of how they work at the molecular level. Researchers upend what's known about how rechargeable batteries function.
Published New research reveals extreme heat likely to wipe out humans and mammals in the distant future



A new study shows unprecedented heat is likely to lead to the next mass extinction, akin to when the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.
Published Researchers' analysis of perching birds points to new answers in evolutionary diversification



When Charles Darwin traveled to the Galapagos Islands almost 200 years ago as a gentleman naturalist, he used the power of observation to develop his theory that species evolve over time.
