⚡️ Energy

🇺🇸 US scientists develop the world's first anode-free sodium solid-state battery

US researchers at the University of Chicago have created the first anode-free sodium solid-state battery, promising inexpensive, fast-charging, high-capacity storage for electric vehicles and grid applications. By eliminating the anode and utilizing abundant sodium, this battery is more affordable and environmentally friendly than traditional lithium batteries. This breakthrough could significantly aid the transition to renewable energy by providing a scalable, sustainable battery solution. The findings were published in Nature Energy.

🇰🇷 Korean researchers double the energy density of redox flow battery by replacing Vanadium with a low-cost material

South Korean scientists have replaced vanadium in redox flow batteries with organic compounds called viologens, doubling the energy density. This advancement addresses the high demand and limited reserves of vanadium by using easily available carbon and oxygen molecules. The new design enhances battery stability and performance, offering a sustainable and scalable energy storage solution crucial for the adoption of renewable energy technologies. The study, highlighting significant improvements in battery efficiency and capacity retention, was published in ACS Applied Materials and Interfaces.

🦾 Robotics

🇺🇸 US researchers create portable engine for artificial muscles in assistive devices

US scientists have developed a lightweight, powerful fluidic engine that can power soft robots, mimicking muscle behavior for assistive devices. This untethered engine, created by researchers at North Carolina State University, generates up to 580 Newtons of force without needing an external power source, significantly advancing the practicality and efficiency of soft robotics. This innovation holds potential for improving mobility and quality of life for individuals requiring assistive technology. The findings were published in Advanced Intelligent Systems.

🌎 Environment

🇺🇸 US researchers develop a new method to recycle mixed fiber textiles, reducing fast fashion waste

US scientists from the University of Delaware have created a chemical process using microwave-assisted glycolysis with zinc oxide to recycle mixed fiber textiles. This innovative method efficiently separates polyester, nylon, cotton, and spandex, addressing the compositional complexity of mixed textile waste. The process reduces reaction times and environmental impact, making large-scale recycling feasible and economically viable. This advancement could significantly reduce the fast fashion industry's 92 million tons of annual textile waste. The study was published in Science Advances.

💊 Healthcare

🇺🇸 US scientists develop bio-inspired hydrogel to heal spinal cord injuries

US researchers have created a bio-inspired hydrogel that significantly enhances nerve regrowth and tissue repair in spinal cord injuries. Comprising hyaluronic acid-graft-dopamine (HADA) and a designer peptide (HRR), this hydrogel transforms scar tissue into a supportive environment for nerve healing. Enhanced with curcumin and Neurotrophin-3 (NT-3), the hydrogel improved motor, sensory, and bladder functions in rats and motor functions in canines. This innovation shows promise for repairing other central nervous system injuries and diseases. The study was published in Science Advances.

🇺🇸 US researchers develop python teeth-inspired device for stronger rotator cuff surgeries

US scientists at Columbia University have created a surgical device inspired by python teeth to enhance rotator cuff repairs. This innovative device, designed by Dr. Stavros Thomopoulos and his team, nearly doubles the strength of tendon-to-bone reattachments, significantly reducing the risk of re-tearing. The biomimetic device uses small, backward-curving teeth to grip soft tissue without cutting through it, offering a more secure attachment. The device could revolutionize rotator cuff surgery, benefiting millions of patients annually. The study was published in Science Advances.

🇺🇸 US researchers discover a way to turn cancer’s defense into a deadly weakness

US scientists at Oregon State University have found compounds that transform the Bcl-2 protein, which typically protects cancer cells, into a protein that kills them. This breakthrough offers new treatment possibilities for breast cancer and other cancers that resist drugs. The research, focusing on aggressive triple-negative breast cancer, showed promising results in lab cultures and mouse models, including preventing metastasis to the lungs. These findings could lead to more effective cancer treatments, advancing towards clinical trials. The studies were published in Cancer Research Communications and ACS Pharmacology & Translational Science.
