The brain is inarguably the single most important organ in the human body. It controls how we move, react, think and feel, and enables us to have complex emotions and memories. The brain is composed of approximately 86 billion neurons that form a complex network. These neurons receive, process, and transfer information using chemical and electrical signals.

You read that right, a hologram doctor.

It’s not science fiction: Hologram doctors beamed to space to visit astronauts.

In 2021, a team of hologram doctors was “holoported” to space to visit astronauts living aboard the International Space Station, NASA has revealed in a new post. The hologram teams, led by NASA flight surgeon Dr. Josef Schmid and Fernando De La Peña Llaca, CEO of software provider Aexa Aerospace, were the first humans to ever be “holoported” from Earth to space.

The word fractal has become increasingly popular, although the concept started more than two centuries ago in the 17th century with prominent and prolific mathematician and philosopher Gottfried Wilhelm Leibnitz is believed to have addressed for the first time the notion of recursive self-similarity, and it wasn’t until 1960 that the concept was formally stabilized both theoretically and practically, through the mathematical development and computerized visualizations by Benoit Mandelbrot, who settled on the name “fractal”.

“All too often we do not recognize the connection between the way we plan our cities and urban development and the health of the citizens who live in those communities. We must connect the dots.” — Dr. Mili Roy, Co-Chair, CAPE.

In a new report now published in Nature Communications Physics, Pedro R. Dieguez and an international team of scientists in quantum technologies, functional quantum systems and quantum physics, developed a new framework of operational criterion for physical reality. This attempt facilitated their understanding of a quantum system directly via the quantum state at each instance of time. During the work, the team established a link between the output visibility and elements of reality within an interferometer. The team provided an experimental proof-of-principle for a two-spin-½ system in an interferometric setup within a nuclear magnetic resonance platform. The outcomes validated Bohr’s original formulation of the complementarity principle.

Physics according to Niels Bohr

Bohr’s complementarity principle states that matter and radiation can be submitted to a unifying framework where either element can behave as a wave or a particle, based on the experimental setup. According to Bohr’s natural philosophy, the nature of individuality of quantum systems is discussed relative to the definite arrangement of whole experiments. Almost a decade ago, physicists designed a quantum delayed choice experiment (QDCE), with a beam splitter in spatial quantum superposition to render the interferometer to have a “closed + open” configuration, while the system represented a hybrid “wave + particle” state. Researchers had previously coupled a target system to a quantum regulator and tested these ideas to show how photons can exhibit wave-like or particle-like behaviors depending on the experimental technique used to measure them.

Remote robotic-assisted surgery is far from new, with various educational and research institutions developing machines doctors can control from other locations over the years. There hasn’t been a lot of movement on that front when it comes to endovascular treatments for stroke patients, which is why a team of MIT engineers has been developing a telerobotic system surgeons can use over the past few years. The team, which has published its paper in Science Robotics, has now presented a robotic arm that doctors can control remotely using a modified joystick to treat stroke patients.

That arm has a magnet attached to its wrist, and surgeons can adjust its orientation to guide a magnetic wire through the patient’s arteries and vessels in order to remove blood clots in their brain. Similar to in-person procedures, surgeons will have to rely on live imaging to get to the blood clot, except the machine will allow them to treat patients not physically in the room with them.

The SENS Research Foundation Board of Directors has a singular focus – to help the Foundation develop, promote, and ensure widespread access to therapies that cure and prevent the diseases and disabilities of aging. As the body responsible for ensuring the organization’s alignment with its mission, it is important our Board comprise leaders within the longevity field – visionaries dedicated to defeating the effects of aging permanently.

Many supporters have followed with interest our recent separation from our co-Founder Dr. Aubrey de Grey, and some have expressed concern regarding the possibility of our mission focus drifting off course. We remain firmly on-mission and continue to make real progress in our field, however, we acknowledge that we are the foundation we are today because of Dr. de Grey’s vision and leadership within the longevity movement. With this in mind, we have formally offered Dr. de Grey a Directorship within the Board of Directors.

His installment as a Director will be effective immediately upon the successful completion of the recommendations made by the accredited professional he has personally engaged, with a subsequent letter of recommendation to the Board of Directors supporting Dr. de Grey’s ability to fulfill the duties of Directorship. In this capacity, Dr. de Grey would lend his expertise to help steer the vision of the Foundation. Consistent with good governance and past practices, Dr. de Grey and the other members of the Board will approve the annual budget, review the annual audit, interview and hire executives, act as advocates for SRF, and largely ensure that the mission is being adhered to by the organization.
