High-nickel cathodes are promising for improving the energy density of lithium-ion batteries (LIBs). However, their high nickel concentration leads to intense side reactions, degrading safety and stability. While full concentration gradient (FCG) design can address this issue, current approaches limit design flexibility. Now, researchers have developed a novel mathematical framework that, combined with an automated reactor system, allows unlimited customization of FCGs with independent parameter control, leading to LIBs with enhanced safety and stability.

A new study led by Virginia Tech found that volunteer dog-handler teams — made up of everyday people and their pets — can effectively detect the elusive egg masses of the spotted lanternfly, an invasive insect that's damaging farms and forests across the eastern and central United States.

Existing three-dimensional (3D) neuronal culture technology has limitations in brain research due to the difficulty of precisely replicating the brain's complex multilayered structure and the lack of a platform that can simultaneously analyze both structure and function. A KAIST research team has successfully developed an integrated platform that can implement brain-like layered neuronal structures using 3D printing technology and precisely measure neuronal activity within them.

Kyoto, Japan -- Respiratory infections such as COVID-19 have been responsible for numerous pandemics and have placed a substantial burden on healthcare systems. Such viruses can cause significant damage to our lungs, especially to the proximal region, or airway, and distal region, also known as the alveoli.

The responses of different lung regions to such infections are varying and complex, so accurately replicating them using traditional models, such as animals and simple in vitro systems, poses a challenge.

To solve this problem, a team of researchers at Kyoto University has developed a micro physiological system, or MPS, capable of emulating different regions of human lungs. Specifically, their device can simulate the airway and alveoli to investigate viral pathologies. Coupled with isogenic iPSCs, the team is preparing for more personalized and accurate treatment of respiratory diseases.
