Researchers have found a way to enhance radiation therapy using novel iodine nanoparticles.

Cancer cell death is triggered within three days when X-rays are shone onto tumor tissue containing iodine-carrying nanoparticles. The iodine releases electrons that break the tumor’s DNA, leading to cell death. The findings, by scientists at Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS) and colleagues in Japan and the US, were published in the journal Scientific Reports.

“Exposing a metal to light leads to the release of electrons, a phenomenon called the photoelectric effect. An explanation of this phenomenon by Albert Einstein in 1905 heralded the birth of quantum physics,” says iCeMS molecular biologist Fuyuhiko Tamanoi, who led the study. “Our research provides evidence that suggests it is possible to reproduce this effect inside cancer cells.”

A new study by engineers at MIT, Caltech, and ETH Zürich shows that “nanoarchitected” materials—materials designed from precisely patterned nanoscale structures—may be a promising route to lightweight armor, protective coatings, blast shields, and other impact-resistant materials.

The researchers have fabricated an ultralight material made from nanometer-scale carbon struts that give the material toughness and mechanical robustness. The team tested the material’s resilience by shooting it with microparticles at supersonic speeds, and found that the material, which is thinner than the width of a human hair, prevented the miniature projectiles from tearing through it.

The researchers calculate that compared with steel, Kevlar, aluminum, and other impact-resistant materials of comparable weight, the new material is more efficient at absorbing impacts.

The innovative material that creates green energy through mechanical force.

A new nanotechnology development by an international research team led by Tel Aviv University researchers will make it possible to generate electric currents and voltage within the human body through the activation of various organs (mechanical force). The researchers explain that the development involves a new and very strong biological material, similar to collagen, which is non-toxic and causes no harm to the body’s tissues. The researchers believe that this new nanotechnology has many potential applications in medicine, including harvesting clean energy to operate devices implanted in the body (such as pacemakers) through the body’s natural movements, eliminating the need for batteries.

The study was led by Prof. Ehud Gazit of the Shmunis School of Biomedicine and Cancer Research at the Wise Faculty of Life Sciences, the Department of Materials Science and Engineering at the Fleischman Faculty of Engineering, and the Center for Nanoscience and Nanotechnology, along with his lab team, Dr. Santu Bera and Dr. Wei Ji.

Adding absorbent nanoparticles to polymer membranes simplifies desalination.

University of California, Berkeley, chemists have discovered a way to simplify the removal of toxic metals. like mercury and boron. during desalination to produce clean water, while at the same time potentially capturing valuable metals, such as gold.

Desalination — the removal of salt — is only one step in the process of producing drinkable water, or water for agriculture or industry, from ocean or waste water. Either before or after the removal of salt, the water often has to be treated to remove boron, which is toxic to plants, and heavy metals like arsenic and mercury, which are toxic to humans. Often, the process leaves behind a toxic brine that can be difficult to dispose of.

As someone with a passionate interest in longevity, transhumanism and biological immortality — I am naturally both excited and optimistic that medical technology will continue to advance in my lifetime — hopefully to the point where humanity has cured or at least greatly mitigated the signs & symptoms of most diseases as well as disabilities, radically expanded human biological lifespan regardless of age, and created a more dignified existence for all as a result of rapid breakthroughs in robotics, AI, automation, nanotechnology, 3D printing and biotechnology — which I hope in turn will largely eradicate poverty, disease, food & shelter insecurity, natural resource scarcity, environmental degradation and income inequality. I know that some of my likeminded friends are far more skeptical that we will ever see outright cures or significant mitigations for major diseases and disabilities — much less radical life extension or perhaps biological immortality in human beings — which are widely available on a commercial basis. They cite their belief that pharmaceutical giants, a plethora of not for profit organizations (i.e., American Cancer Society), and many other allegedly “self-interested parties” supposedly allied with government regulatory bodies — apparently do not want to see diseases or disabilities cured or lifespan significantly extended — EVER — as this would prevent them from earning untold sums selling treatments and supports for such things on a regular ongoing basis (i.e., chemo drugs for cancer, statins for cardiovascular disease, inhaled/oral steroids for lung disease, renal replacement therapy for kidney disease, mobile supports for spinal cord injuries, ect.) They believe that too much money would be at stake, too many jobs on the line and the entire “pharma-medical-academic industrial complex” supposedly at great risk, if actual cures or significant mitigations ever saw the light of day. Some of these friends even cite their belief that fully autonomous, accident proof, self-driving cars will most likely never occur — as it would supposed put the entire auto insurance industry at existential risk as well as deprive law enforcement agencies of a key source of reliable revenue (issuing speeding tickets) This one makes me giggle! 🤭 My friends also believe that radical life extension in human beings — much less biological immortality — would apparently upset the proverbial apple cart — where the “powers that be” are concerned — in terms of everything from the highly lucrative profits which are derived from pharmaceutical sales, old age homes, life and health insurance plans, personal financial services and all of the sales of key products and services associated with the aging process — to macroeconomic considerations such as the long term viability of government entitlement programmes. They believe that government regulatory authorities allegedly working at the behest of the aforementioned self-interested parties will always seek to delay, disrupt or even derail ANY and ALL significant progress into cures/mitigations for disease/disabilities, radical human life extension and/or human biological immortality. Apparently, new biotech start ups which do advance the aforementioned things are allegedly “always aggressively bought out by monopoly capital — with their cures and advances indefinitely suppressed” I personally tend to be more on the positive and optimistic side where these things are concerned — but perhaps these rather pessimistic arguments do have some validity — minus the implied conspiracy theory aspect. Do you think human beings will ever be “allowed” to truly be free from illnesses and disabilities? Will we ever be “permitted” to radically expand our lifespans or even become biologically immortal at some point? Please discuss.

I have already taken a few courses for a master’s in physics at the University of Antwerp and I want to complete it there. In a bachelor’s degree you get a basis of knowledge in physics and quantum physics, but it gets more detailed in a master’s.

The main reason I chose to study physics is because my end goal is to achieve immortality. One of the areas that is important in the study of immortality is physics, but as of yet, there is no mapped out path to achieve it.

They’re tiny machines that work on the nanoscale, being up to 100000 times smaller than the width of a human hair. These machines, otherwise known as nanorobotics, are set to augment the human race in unforeseen ways.

However, this microscopic technology has remained in the prototype phase for the past two decades, failing to truly live up to its promise, and lagging due to difficult manufacturing processes, a lack of standardization, and scant reviews of the available literature.

Picture a scenario where you’re ill and need to see your doctor. However, instead of giving you a pill or a shot, your doctor injects you with a swarm of tiny robots.

Very recently, researchers led by Markus Aspelmeyer at the University of Vienna and Lukas Novotny at ETH Zurich cooled a glass nanoparticle into the quantum regime for the first time. To do this, the particle is deprived of its kinetic energy with the help of lasers. What remains are movements, so-called quantum fluctuations, which no longer follow the laws of classical physics but those of quantum physics. The glass sphere with which this has been achieved is significantly smaller than a grain of sand, but still consists of several hundred million atoms. In contrast to the microscopic world of photons and atoms, nanoparticles provide an insight into the quantum nature of macroscopic objects. In collaboration with experimental physicist Markus Aspelmeyer, a team of theoretical physicists led by Oriol Romero-Isart of the University of Innsbruck and the Institute of Quantum Optics and Quantum Information of the Austrian Academy of Sciences is now proposing a way to harness the quantum properties of nanoparticles for various applications.

Briefly delocalized

“While atoms in the motional ground state bounce around over distances larger than the size of the atom, the motion of macroscopic objects in the ground state is very, very small,” explain Talitha Weiss and Marc Roda-Llordes from the Innsbruck team. “The quantum fluctuations of nanoparticles are smaller than the diameter of an atom.” To take advantage of the quantum nature of nanoparticles, the wave function of the particles must be greatly expanded. In the Innsbruck quantum physicists’ scheme, nanoparticles are trapped in optical fields and cooled to the ground state. By rhythmically changing these fields, the particles now succeed in briefly delocalizing over exponentially larger distances. “Even the smallest perturbations may destroy the coherence of the particles, which is why by changing the optical potentials, we only briefly pull apart the wave function of the particles and then immediately compress it again,” explains Oriol Romero-Isart.

The researchers explain that the development involves a new and very strong biological material, similar to collagen, which is non-toxic and causes no harm to the body’s tissues. The researchers believe that this new nanotechnology has many potential applications in medicine, including harvesting clean energy to operate devices implanted in the body (such as pacemakers) through the body’s natural movements, eliminating the need for batteries.

The study was led by Prof. Ehud Gazit of the Shmunis School of Biomedicine and Cancer Research at the Wise Faculty of Life Sciences, the Department of Materials Science and Engineering at the Fleischman Faculty of Engineering and the Center for Nanoscience and Nanotechnology, along with his lab team, Dr. Santu Bera and Dr. Wei Ji.

Also taking part in the study were researchers from the Weizmann Institute and a number of research institutes in Ireland, China and Australia. As a result of their findings, the researchers received two ERC-POC grants aimed at using the scientific research from the ERC grant that Gazit had previously won for applied technology. The research was published in the prestigious journal Nature Communications.
