Producing gold nano-particles (and hydrogen) in water without the need for toxic chemicals

Posted by in categories: chemistry, nanotechnology, particle physics

In a surprise discovery, Flinders University nanotechnology researchers have produced a range of different types of gold nanoparticles by adjusting water flow in the novel vortex fluidic device—without the need for toxic chemicals. The article, “Nanogold Foundry Involving High-Shear-Mediated Photocontact Electrification in Water,” has been published in Small Science.

Ford teases new F-150 Lightning-based EV SuperTruck ahead of Pikes Peak [Video]

Posted by in categories: climatology, sustainability

Ford Performance is at it again. The high-performance unit is teasing its new Ford F-150 Lightning-based EV SuperTruck ahead of its official debut. To showcase its abilities, Ford’s new electric SuperTruck will compete in the upcoming Pikes Peak International Hill Climb.

Based on its best-selling electric pickup, Ford’s Performance team tweaked the Lightning-based EV SuperTruck to boost power and aerodynamics.

Ford says running test electric vehicles at Pikes Peak enables it to “push the boundaries of EV powertrains in the most extreme conditions.” The team then relays what it learns to improve Ford’s production vehicles.

Researchers develop new electrode binder material for high-performance sodium-ion batteries

Posted by in categories: energy, materials

Lithium-ion batteries have been at the forefront of energy storage technologies. However, the availability of lithium is limited. Consequently, the growing demand for energy-storage systems has led to the search for low-cost and more accessible materials for rechargeable batteries. Sodium-ion batteries (SIBs) are a promising candidate due to the virtually unlimited sodium (Na) resources in seawater and salt deposits.

Top US coal producer Wyoming just approved a $1.2B solar farm

Posted by in categories: solar power, sustainability

Wyoming just approved its largest solar farm – 771 megawatts (MW) of utility-scale solar plus battery storage.

Developer Enbridge has been issued a siting permit by the Industrial Siting Council to construct and operate Cowboy Solar I & II on private land leases in Laramie County, in the state’s southeast corner. Next steps will be to obtain county, environmental, and municipal permits.

Cowboy Solar I will include 400 MW of solar power and 136 MW of battery storage, while Cowboy Solar II will have 371 MW of solar power and 133 MW of battery storage.

T Cell Activation and Proliferation: The Three Signal Process

Posted by in category: biotech/medical

The immune system provides an integral defense against cancer growth and progression. Activating an anti-tumor immune response relies on several biological steps that can ultimately result in the elimination of tumor cells. T cell activation, a process requiring three “signals,” is required for optimal anti-tumor immunity.

T cells, immune cells generated in the thymus, have a programmed affinity for a specific particle foreign to the body. T cells must become specially “trained” to recognize this foreign protein, known as an antigen. After leaving the thymus, T cells circulate throughout the body in search of their antigen.

Antigen presenting cells (APCs) comprise another category of immune cells required for effective anti-tumor immunity. APCs also circulate the body, where they locate, process, and “present” pieces of antigen on their surface. A surface molecule called a major histocompatibility complex (MHC) holds the antigen on the outside of the APC.

The new Kia EV3 will have an AI assistant with ChatGPT DNA

Posted by in categories: biotech/medical, robotics/AI

The Kia EV3 — the new all-electric compact SUV revealed Thursday — illustrates a growing appetite among global automakers to bring generative AI into their vehicles.

The automaker said the Kia EV3 will feature a new voice assistant that is built off ChatGPT, the text-generating AI chatbot developed by OpenAI. The Kia EV3, and its AI assistant, will first come to market in Korea in July 2024, followed by Europe in the second half of the year. Kia expects to expand sales of the vehicle into other regions following the European launch. It will eventually come to the United States, although the automaker did not provide a date.

This isn’t, however, a pure OpenAI affair. Kia had its hands in the development of the voice assistant too.

Proteins Found to Drive Lupus Symptoms

Posted by in category: biotech/medical

A recent article in Cell Reports Medicine, by Dr. Felipe Andrade, uncovers insights into lupus symptoms. More specifically, how these symptoms can range in severity among individuals. Andrade is a principal investigator and Associate Professor at the Johns Hopkins School of Medicine and specializes in rheumatology. His work focuses on the mechanisms of systemic autoimmune disease and the role of proteins that mediate this mechanism.

Lupus is an autoimmune disorder in which the body attacks its own tissues and cells. A chronic inflammatory disease, lupus affects about 1.5 million Americans. While the cause of lupus is unknown, there are several subsets including, systemic lupus erythematosus (SLE), cutaneous lupus, drug-induced lupus, and neonatal lupus. The most common subset is SLE with symptoms that include muscle/joint pain, fever, rashes, chest pain, hair loss, fatigue, mouth sores, kidney issues, and others. Unfortunately, there is no cure for lupus, but medication and lifestyle changes help moderate the symptoms. Medication that prevents or reduces inflammation are usually prescribed with other therapies that target pain and protect tissue damage.

Andrade and others explored the underlying mechanism that drives lupus. Researchers conclude that immune proteins, known as interferons, are elevated in lupus and can cause lupus-related symptoms including rashes, chest pain, fatigue, and soreness. Interferons help regulate inflammation and attract immune cells to the site of infection. In a healthy immune system interferon helps fight off infection. However, in the context of lupus, the protein helps to prolong inflammation that causes deterioration of tissues and cells.
