In an innovative approach to combating climate change, scientists have formed an unexpected alliance with bacteria to extract rare metals crucial for green technology. Without the aid of these microbes, the world could soon face a shortage of raw materials needed to build essential components like turbines, electric cars, and solar panels.

Leading this groundbreaking work is a team from the University of Edinburgh, which is focusing on harnessing bacteria to extract valuable metals such as lithium, cobalt, and manganese from discarded batteries and electronic waste. These scarce and costly metals are essential for producing electric cars and other green technologies, a fact emphasized by Professor Louise Horsfall, chair of sustainable biotechnology at Edinburgh.

Researchers from EPFL have developed a groundbreaking miniaturized brain-machine interface (BMI) capable of translating brain activity into text on tiny silicon chips. This next-generation technology, known as the Miniaturized Brain-Machine Interface (MiBMI), promises to revolutionize communication for individuals with severe motor impairments.

Brain-machine interfaces have long held the potential to restore communication and control to people with conditions such as amyotrophic lateral sclerosis (ALS) and spinal cord injuries. However, traditional BMIs have been bulky, power-hungry, and limited in practical applications. The new MiBMI, developed by EPFL’s Integrated Neurotechnologies Laboratory (INL), overcomes these challenges by offering a compact, low-power, and highly accurate solution.

Eggshells, primarily composed of calcium carbonate, have long been used in various areas such as feed supplements and garden pest control. Now, groundbreaking research is revealing an innovative application: growing tissue for implants that can replace damaged or diseased bone and cartilage. This pioneering approach could revolutionize the field of medicine.

The research, led by Prof. Dr. Gulden Camci-Unal from the Department of Chemical Engineering at the University of Massachusetts Lowell, explores a novel method of repurposing eggshells. Despite their widespread use in other industries, their potential in medicine has been largely untapped until now. Since 2016, Camci-Unal and her team have been dedicated to utilizing finely crushed eggshells to create tiny 3D structures, known as scaffolds, where bone cells can grow and multiply.

A newly modified CART neuropeptide has demonstrated remarkable stability, appetite reduction, and brain protection against harmful tau proteins linked to Alzheimer’s disease. This breakthrough research, recently published in the European Journal of Pharmacology, has shown promising results in both cellular and animal tests.

In experiments, the modified compound led to significant weight loss in higher-weight mice and reduced the presence of tau protein in their brains—a key marker associated with Alzheimer’s. The success of this compound lies in its modification with fatty acids, which enhance its ability to cross the blood-brain barrier. This improved delivery allows the neuropeptide to effectively reduce appetite and offer neuroprotective benefits, making it a potential candidate for treating or preventing neurodegenerative diseases, according to researcher Vilém Charvát.

As the demand for animal products continues to rise, cellular agriculture offers a promising solution. However, current production technologies for cultivated meat face significant challenges, particularly in achieving scalability and cost-effectiveness. A groundbreaking study from the Hebrew University of Jerusalem, in collaboration with the cultivated meat industry, has introduced an innovative continuous manufacturing process that could overcome these hurdles, potentially making cultivated meat accessible to everyday consumers and contributing to a more sustainable and ethical food system.

Innovative Production Method

The researchers employed tangential flow filtration (TFF) to continuously produce cultivated meat, achieving an impressive biomass density of up to 130 billion cells per liter and a yield of 43% weight per volume. This process was maintained over a 20-day period, allowing for daily biomass harvests. Crucially, the study also developed a growth medium free of animal components, costing just $0.63 per liter. This medium is specifically designed to support the high-density, long-term culture of chicken cells, making the process both more affordable and scalable.

Researchers in Korea have made a groundbreaking advancement in the quest to develop eco-friendly plastics by engineering bacteria to produce polymers with ring-like structures. These structures significantly enhance the rigidity and thermal stability of the resulting plastics, offering a promising alternative to traditional petroleum-based plastics.

Senior author Sang Yup Lee emphasized the potential impact of this innovation, stating, “I think biomanufacturing will be key to mitigating climate change and addressing the global plastic crisis.”
