Scientists invent particles that will provide oxygen to your body without breathing!!!
This may seem like something out of a science fiction movie: researchers have designed microparticles that can be injected directly into the bloodstream to quickly oxygenate your body, even if you can’t breathe anymore. It’s one of the best medical breakthroughs in recent years, and one that could save millions of lives every year.
The invention, developed by a team at Boston Children’s Hospital, will allow medical teams to keep patients alive and well for 15 to 30 minutes despite major respiratory failure. This is enough time for doctors and emergency personnel to act without risking a heart attack or permanent brain injuries in the patient.

A team of scientists at the Boston Children’s Hospital have invented what is being considered one the greatest medical breakthroughs in recent years. They have designed a microparticle that can be injected into a person’s bloodstream that can quickly oxygenate their blood. This will even work if the ability to breathe has been restricted, or even cut off entirely.
This finding has the potential to save millions of lives every year. The microparticles can keep an object alive for up to 30 min after respiratory failure. This is accomplished through an injection into the patients’ veins. Once injected, the microparticles can oxygenate the blood to near normal levels. This has countless potential uses as it allows life to continue when oxygen is needed but unavailable. For medical personnel, this is just enough time to avoid risking a heart attack or permanent brain injury when oxygen is restricted or cut off to patients.
Transhumanists will know that the science fiction author Zoltan Istvan has unilaterally leveraged the movement into a political party contesting the 2016 US presidential election. To be sure, many transhumanists have contested Istvan’s own legitimacy, but there is no denying that he has generated enormous publicity for many key transhumanist ideas. Interestingly, his lead idea is that the state should do everything possible to uphold people’s right to live forever. Of course, he means to live forever in a healthy state, fit of mind and body. Istvan cleverly couches this policy as simply an extension of what voters already expect from medical research and welfare provision. And while he may be correct, the policy is fraught with hazards – especially if, as many transhumanists believe, we are on the verge of revealing the secrets to biological immortality.
In June, Istvan and I debated this matter at Brain Bar Budapest. Let me say, for the record, that I think that we are sufficiently close to this prospect that it is not too early to discuss its political and economic implications.
Two months before my encounter with Istvan, I was on a panel at the Edinburgh Science Festival with the great theorist of radical life extension Aubrey de Grey, where he declared that people who live indefinitely will seem like renovated vintage cars. Whatever else, he is suggesting that they would be frozen in time. He may actually be right about this. But is such a state desirable, given that throughout history radical change has been facilitated generational change? Specifically, two simple facts make the young open to doing things differently: The young have no memory of past practices working to anyone else’s benefit, and they have not had the time to invest in those practices to reap their benefits. Whatever good is to be found in the past is hearsay, as far as the young are concerned, which they are being asked to trust as they enter a world that they know is bound to change.
Questions have been already raised about whether tomorrow’s Methuselahs will wish to procreate at all, given the time available to them to realize dreams that in the past would have been transferred to their offspring. After all, as human life expectancy has increased 50% over the past century, the birth rate has correspondingly dropped. One can only imagine what will happen once ageing can be arrested, if not outright reversed!
Quantum physics: The human body is controlled by electrical impulses in, for example, the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various diseases, for example diseases of the brain or heart problems in young foetuses. Researchers from the Niels Bohr Institute have now succeeded in developing a method for extremely precise measurements of such ultra-small magnetic fields with an optical magnetic field sensor. The results are published in the scientific journal, Scientific Reports.

Small magnetic fields from the human body can usually only be picked up by very sensitive superconducting magnetic field sensors that have to be cooled by liquid helium to near absolute zero (which is minus 273 degrees Celsius). But now researchers from the Niels Bohr Institute at the University of Copenhagen have developed a much cheaper and more practical optical magnetic field sensor that even works at room temperature or at body temperature.

Human brain is made up of a billion nerve cells called neurons and various other types of cells and is the most complex machine ever known. Even after years of research and studies we still do not have a complete understanding of how it works — how it controls every single thing we ever do. In order to unravel one such mysteries of the brain, researchers at the Carnegie Mellon University set out to find out why brain makes mistakes. The study was conducted as part of Carnegie Mellon’s BrainHub, a university initiative that focuses on how the structure and activity of the brain give rise to complex behaviors.
Researchers at the University of California, Riverside have developed a transparent “window to the brain” — a skull implant that is biocompatible, infection-resistant, and does not need to be repetitively replaced.
Part of the ongoing “Window to the Brain” project, a multi-institution, cross-disciplinary effort, the idea is to use transparent skull implants to provide laser diagnosis and treatment of a wide variety of brain pathologies, including brain cancers, traumatic brain injury, stroke, and neurodegenerative diseases, without requiring repeated craniotomies (a surgical operation in which a bone flap is temporarily removed from the skull to access the brain). Such operations are vulnerable to bacterial infections.
