This 3D-printed hydraulic turbine provides energy without blades

Posted by in categories: energy, food, military, sustainability

It generates energy by forcing the stream to form a vortex.

Without employing any blades, the transportable hydraulic turbine SETUR from Vortex Hydrokinetics serves as a power source. The water source could be rivers, tidal streams, ocean currents, or even canals.

Researchers create new system for safer gene-drive testing and development

Posted by in categories: biotech/medical, food, genetics, health

Scientists continue to expand the technological frontiers of CRISPR, along with its enormous potential, in areas ranging from human health to global food supplies. Such is the case with CRISPR-based gene drives, a genetic editing tool designed to influence how genetic elements are passed from one generation to the next.

Gene drives designed for mosquitoes have the potential to curb the spread of malarial infections that cause hundreds of thousands of deaths each year, yet have been raised because such drives can spread quickly and dominate entire populations. Scientists have explored the principles governing the spread of gene-drive elements in targeted populations such as mosquitoes by testing many different combinations of components that constitute the drive apparatus. They have found, however, that there’s still more to explore and that key questions remain.

In the journal Nature Communications, University of California San Diego researchers led by former Postdoctoral Scholar Gerard Terradas, together with Postdoctoral Scholar Zhiqian Li and Professor Ethan Bier, in close collaboration with UC Berkeley graduate student Jared Bennett and Associate Professor John Marshall, describe the development of a new system for testing and developing gene drives in the laboratory and safely converting them into tools for potential real-world applications.

Humans plunder the periodic table while turning blind eye to the risks of doing so, say researchers

Posted by in categories: biological, chemistry, computing, food, health, mobile phones

For millions of years, nature has basically been getting by with just a few elements from the periodic table. Carbon, calcium, oxygen, hydrogen, nitrogen, phosphorus, silicon, sulfur, magnesium and potassium are the building blocks of almost all life on our planet (tree trunks, leaves, hairs, teeth, etc). However, to build the world of humans—including cities, health care products, railways, airplanes and their engines, computers, smartphones, and more—many more chemical elements are needed.

A recent article, published in Trends in Ecology and Evolution and written by researchers from CREAF, the Universitat Autònoma de Barcelona (UAB) and the Spanish National Research Council (CSIC), warns that the range of chemical elements humans need (something scientifically known as the human elementome) is increasingly diverging from that which nature requires (the biological elementome).

In 1900, approximately 80% of the elements humans used came from biomass (wood, plants, food, etc.). That figure had fallen to 32% by 2005, and is expected to stand at approximately 22% in 2050. We are heading for a situation in which 80% of the elements we use are from non-biological sources.

AI-Developed, Synthetic DNA is About to Revolutionize Drug Production and Gene Therapy

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

Researchers at Chalmers University of Technology have made a ground-breaking discovery in the field of synthetic DNA, using AI to control the cells’ protein production.

This new technology could revolutionize the way we produce vaccines, drugs for severe diseases, and alternative food proteins by making the process faster and significantly cheaper than current methods.

The process of gene expression is fundamental to the function of cells in all living organisms. In simple terms, the genetic code in DNA is transcribed into the molecule messenger RNA (mRNA), which tells the cell’s factory which protein to produce and in what quantities.

Largest global bird flu outbreak ‘in history’ shows no sign of slowing

Posted by in categories: biotech/medical, food

A lethal bird flu outbreak that has been circling the globe since 2021 peaked in Japan this week, as an agriculture ministry official said on Tuesday the country plans to cull more than 10 million chickens at risk of exposure to the virus.

Flu is a common annual illness among wild birds yet the H5N1 strain now sweeping Japan is uniquely contagious and deadly. It poses such high risk to farmed birds, such as chickens and turkeys, that a single infection on a farm condemns the entire flock to be killed. As outbreaks in Japan have reached a record high, the cull is the largest ever planned for the yearly flu season that runs from October to May.

Around the globe, record-breaking death tolls due to the virus are becoming the norm. In the US, more states than ever before have reported instances of bird flu with an all-time high of nearly 58 million poultry affected as of January 2023.

Scientists Have Developed a Living “Bio-Solar Cell” That Runs on Photosynthesis

Posted by in categories: biological, food, solar power, sustainability

Plants are often thought of as sources of food, oxygen, and decoration, but not as a source of electricity. However, scientists have discovered that by harnessing the natural transport of electrons within plant cells, it is possible to generate electricity as part of a green, biological solar cell. In a recent study published in ACS Applied Materials & Interfaces, researchers for the first time used a succulent plant to create a living “bio-solar cell” that runs on photosynthesis.

Photosynthesis is how plants and some microorganisms use sunlight to synthesize carbohydrates from carbon dioxide and water.

How the Immune System Tolerates Gut Bacteria

Posted by in categories: biotech/medical, food

Our immune system is built to detect foreign invaders, pathogens, and debris, and then eliminate them. So how does it deal with the trillions of microbial cells that make a home for themselves in our gastrointestinal tract? Scientists have now found an answer to that question, and the evidence they revealed has also changed what we know about the interactions between immune receptors and a protein that helps move bacteria around, called flagellin. The findings have been reported in Science Immunology.

There are many beneficial microbes in the human gut microbiome, and we need many of those microorganisms to help us break down food and absorb nutrients, for example. But there are also pathogenic gut germs. The immune system can recognize those pathogenic microbes with different receptors, one of which is called toll-like receptor 5 (TLR5). TLR5 attaches to flagellin, a protein found in the flagellum of bacteria, a structure that propels bacterial cells. When TLR5 binds to flagellin, an inflammatory response is triggered.

Year 2015 😀


The food that will sustain future generations as we colonise our way across space may be none other than our own sh*t, if a new NASA-funded project is successful.
