Envision a realm where light can be meticulously controlled and manipulated at minuscule scales, unlocking unprecedented potentials for nanotechnology and quantum information technology. Recent breakthroughs in quantum research have propelled us closer to a reality that may be more achievable than previously realized.

In this article, we delve into the domain of surface plasmon polaritons (SPPs) and the vast possibilities they offer in revolutionizing the field of quantum optics.

Picture a serene lake on a sunny day. As you drop a small stone into the water, it sets in motion gentle ripples that traverse the surface. Now, imagine light as akin to those undulating ripples. When light encounters the interface of a metal and a dielectric material, it has the power to generate waves, much like the ripples on the lake. This phenomenon is even more intriguing because these light waves can interact with the metal’s microscopic constituents, such as electrons. Remarkably, the light waves and electrons synchronize their oscillations, giving rise to an SPP wave.

Last year, the chemist – who is an emeritus professor at the University of Strasbourg – published a book titled The Elegance of Molecules. In the pages, he lets his imagination run wild. “Over time, most of the chemical reactions that govern nature could be controlled or imitated by a nanorobot: counter-offensives by the immune system, the production of antibodies, hormones on demand, the repairing of damaged cells and organs [or] the correction of anomalies in the genetic text,” Sauvage writes. “None of this will belong in the realm of science fiction in the long-term.”

Sitting in the hotel’s restaurant, however, the researcher’s realism contrasts with his futuristic fantasy. “Today, we can’t do much. Molecular machines are a somewhat new concept: we can make molecules that move as we choose [and] we can make a fairly complex molecule perform a rotary motion. Or we can make it behave like a muscle, stretching and contracting. The applications will arrive in the future, but we’re not there yet,” he stresses.

The French researcher has been developing these molecular muscles since 2002 alongside a Spanish chemist – María Consuelo Jiménez – from the Polytechnic University of Valencia. “The first thing was to show that we can make a molecule that contracts and stretches. Now, you can think of making materials – especially fibers – that can contract and stretch. Perhaps artificial muscles could be made to replace damaged muscles in people, but that will be in the future. At the moment, there are no real applications,” Sauvage clarifies.

A new technique produces perovskite nanocrystals right where they’re needed, so the exceedingly delicate materials can be integrated into nanoscale.

The nanoscale refers to a length scale that is extremely small, typically on the order of nanometers (nm), which is one billionth of a meter. At this scale, materials and systems exhibit unique properties and behaviors that are different from those observed at larger length scales. The prefix “nano-” is derived from the Greek word “nanos,” which means “dwarf” or “very small.” Nanoscale phenomena are relevant to many fields, including materials science, chemistry, biology, and physics.

Scientists at Leipzig University, in collaboration with colleagues at Vilnius University in Lithuania, have developed a new method to measure the smallest twists and torques of molecules within milliseconds. The method makes it possible to track the gene recognition of CRISPR-Cas protein complexes, also known as “genetic scissors”, in real time and with the highest resolution. With the data obtained, the recognition process can be accurately characterised and modelled to improve the precision of the genetic scissors. The results obtained by the team led by Professor Ralf Seidel and Dominik Kauert from the Faculty of Physics and Earth Sciences have now been published in the prestigious journal Nature Structural and Molecular Biology.

When bacteria are attacked by a virus, they can defend themselves with a mechanism that fends off the genetic material introduced by the intruder. The key is CRISPR-Cas protein complexes. It is only in the last decade that their function for adaptive immunity in microorganisms has been discovered and elucidated. With the help of an embedded RNA, the CRISPR complexes recognize a short sequence in the attacker’s DNA. The mechanism of sequence recognition by RNA has since been used to selectively switch off and modify genes in any organism. This discovery revolutionized genetic engineering and was already honored in 2020 with the Nobel Prize in Chemistry awarded to Emmanuelle Charpentier and Jennifer A. Doudna.

Occasionally, however, CRISPR complexes also react to gene segments that differ slightly from the sequence specified by the RNA. This leads to undesirable side effects in medical applications. “The causes of this are not yet well understood, as the process could not be observed directly until now,” says Dominik Kauert, who worked on the project as a PhD student.

Scientists have created an innovative model membrane electrode with hollow giant carbon nanotubes and a wide range of nanopore dimensions. The invention aids in understanding electrochemical behaviors and could significantly advance our knowledge of porous carbon materials in electrochemical systems.

Researchers at Tohoku University and Tsinghua University have introduced a next-generation model membrane electrode that promises to revolutionize fundamental electrochemical research. This innovative electrode, fabricated through a meticulous process, showcases an ordered array of hollow giant carbon nanotubes (gCNTs) within a nanoporous membrane, unlocking new possibilities for energy storage and electrochemical studies.

The key breakthrough lies in the construction of this novel electrode. The researchers developed a uniform carbon coating technique on anodic aluminum oxide (AAO) formed on an aluminum substrate, with the barrier layer eliminated. The resulting conformally carbon-coated layer exhibits vertically aligned gCNTs with nanopores ranging from 10 to 200 nm in diameter and 2 μm to 90 μm in length, covering small electrolyte molecules to bio-related large matters such as enzymes and exosomes. Unlike traditional composite electrodes, this self-standing model electrode eliminates inter-particle contact, ensuring minimal contact resistance — something essential for interpreting the corresponding electrochemical behaviors.

Immortality has been a dream of human beings since the dawn of time. Mankind´s fascination with cheating death is reflected in scientific records, mythology, and folklore dating back at least to ancient Egypt.

Now, Ray Kurzweil, a former Google engineer, claims that humans will achieve immortality by 2030 – and 86 percent of his 147 predictions have been correct.

An older research article and I really hope I didn’t already post this, but isn’t this scary? Nevermind AI or nano, but the fact you don’t need that to mess with your mind? Oh and I’ve searched google and there’s nanoparticles in meds, including psych meds. EMF could potentially mess with that or the minerals in your body but I’m not an expert. But we do have iron in our blood. I read that EMF can affect the blood brain barrier as well. I know there’s issues with people saying they’re targeted individuals, but with instructions online on how to make a microwave gun, especially on youtube, and there’s a Wired Magazine article about a court case where a judge ordered a man to stop EMF targeting a former business partner over an argument over a business deal. Yup, the 21st centure is bringing more than guns and knives and fists into the foray.

From our archives. This important article first published by GR in August 2004 brings to the forefront the role of Psychotronic weapons as an instrument of modern warfare.

Using nanostructured glass, scientists from the University of Southampton’s Optoelectronics Research Centre (ORC) have developed the recording and retrieval processes of five dimensional (5D) digital data by femtosecond laser writing.

The storage allows unprecedented properties including 360 TB/disc data capacity, thermal stability up to 1,000°C and virtually unlimited lifetime at room temperature (13.8 billion years at 190°C) opening a new era of eternal data archiving. [source].
