A joint research project’s findings have just been published in the journal Nature Materials from engineers from MIT, Caltech, and ETH Zurich that has yielded a “nano-architectured” material that could prove stronger than Kevlar and steel. This material, once scaled, could provide a means of developed lightweight, protective coverings, blast shields, and other impact-resistance materials and armors for various industries.

The material is less than a width of a human hair, but still able to prevent the tiny, high-speed particles from penetrating it. According to the researchers behind the project, when compared with steel Kevlar, aluminum rother impact-resistant materials of comparable weight, the new nanotech armor outperforms them all.

A biological method that produces metal nanoclusters using the electroactive bacterium Geobacter sulfurreducens could provide a cheap and sustainable solution to high-performance catalyst synthesis for various applications such as water splitting.

Metal nanoclusters contain fewer than one hundred atoms and are much smaller than nanoparticles. They have unique electronic properties but also feature numerous active sites available for catalysis on their surface. There are several synthetic methods for making metal nanoclusters, but most require multiple steps involving toxic substances and harsh temperature and pressure conditions.

Year 2022 😗😁 Basically more thought on this virus seems more like a foglet biotechnology so it would stand to reason that a nanotechnology with biotechnology could solve the universal vaccine.

Ending the covid pandemic might well require a vaccine that protects against any new strains. Researchers may have found a strategy that will work.

Year 2022 This is their published work on the universal vaccine of the covid 19.

A mosaic sarbecovirus nanoparticle protects against SARS-2 and SARS-1, whereas a SARS-2 nanoparticle only protects against SARS-2.

Micron-sized “bow ties,” self-assembled from nanoparticles, form a variety of different curling shapes that can be precisely controlled, a research team led by the University of Michigan has shown.

The development opens the way for easily producing materials that interact with twisted light, providing new tools for machine vision and producing medicines.

While biology is full of twisted structures like DNA, known as chiral structures, the degree of twist is locked in—trying to change it breaks the structure. Now, researchers can engineer the degree of twist.

Researchers at Kanazawa University report in ACS Nano how high-speed atomic force microscopy can be used to study the biomolecular mechanisms underlying gene editing.

The DNA of prokaryotes—single-cell organisms, for example bacteria—is known to contain sequences that are derived from DNA fragments of viruses that infected the prokaryote earlier. These sequences, collectively referred to as CRISPR, for “clustered regularly interspaced short palindromic repeats,” play a major role in the antiviral defense system of bacteria, as they enable the recognition and subsequent neutralization of infecting viruses. The latter is done through the enzyme Cas9 (“CRISPR-associated protein 9”), a biomolecule that can locally unwind DNA, check for the existence of the CRISPR sequence and, when found, cut the DNA.

NPL, in collaboration with London Biofoundry and BiologIC Technologies Ltd, have released an analysis on existing and emerging DNA Synthesis technologies in Nature Reviews Chemistry, featuring the work on the front cover.

The study, which was initiated by DSTL, set out to understand the development trajectory of DNA Synthesis as a major industry drive for the UK economy over the next 10 years. The demand for synthetic DNA is growing exponentially. However, our ability to make, or write, DNA lags behind our ability to sequence, or read, it. The study reviewed existing and emerging DNA synthesis technologies developed to close this gene writing gap.

DNA or genes provide a universal tool to engineer and manipulate living systems. Recent progress in DNA synthesis has brought up limitless possibilities in a variety of industry sectors. Engineering biology, therapy and diagnostics, data storage, defense and nanotechnology are all set for unprecedented breakthroughs if DNA can be provided at scale and low cost.

The animal brain consists of tens of billions of neurons or nerve cells that perform complex tasks like processing emotions, learning, and making judgments by communicating with each other via neurotransmitters. These small signaling molecules diffuse—move from high to low concentration regions—between neurons, acting as chemical messengers.

Scientists believe that this diffusive motion might be at the heart of the brain’s superior function. Therefore, they have aimed to understand the role of specific neurotransmitters by detecting their release in the brain using amperometric and microdialysis methods. However, these methods provide insufficient information, necessitating better sensing techniques.

To this end, scientists developed an optical imaging method wherein protein probes change their fluorescence intensity upon detecting a specific neurotransmitter. Recently, a group of researchers from Shibaura Institute of Technology in Japan led by Professor Yasuo Yoshimi has taken this idea forward. They have successfully synthesized fluorescent molecularly imprinted polymeric nanoparticles (fMIP-NPs) that serve as probes to detect specific neurotransmitters–serotonin, dopamine, and acetylcholine.

Ray Kurzweil — The Singularity IS NEAR — part 2! We’ll Reach IMMORTALITY by 2030
Get ready for an exciting journey into the future with Ray Kurzweil’s The Singularity IS NEAR — Part 2! Join us as we explore the awe-inspiring possibilities of what could be achieved before 2030, including the potential for humans to reach immortality. We’ll dive into the incredible technology that could help us reach this singularity and uncover what the implications of achieving immortality could be. Don’t miss out on this fascinating insight into the future of mankind!
In his book “The Singularity Is Near”, futurist and inventor Ray Kurzweil argues that we are rapidly approaching a point in time known as the singularity. This refers to the moment when artificial intelligence and other technologies will become so advanced that they surpass human intelligence and change the course of human evolution forever.

Kurzweil predicts that by 2030, we will reach a crucial milestone in our technological progress: immortality. He bases this prediction on his observation of exponential growth in various fields such as genetics, nanotechnology, and robotics, which he believes will culminate in the creation of what he calls “nanobots”.
