NASA Virtually Teleports Doctor Hundred of Miles In Space To Show Off ‘Holoportation’

In a remarkable development, the National Aeronautics and Space Administration (NASA) ‘holoported’ the first human being into space late last year. Holoportation is the process through which a three dimensional holographic representation of an individual is created, in a combination of a ‘hologram’ and ‘teleportation’. NASA revealed the development late last week, as it announced that it had transported flight surgeon Dr. Josef Schmid, mixed and virtual reality firm AEXA Aerospance’s chief executive officer Dr. Fernando De La Pena Llaca and others to the International Space Station (ISS) during October 2021 while the ISS was orbiting the Earth at an altitude of 250 miles above the Earth’s surface.

The event place last year when NASA’s Crew 2 astronauts were present on the ISS. The astronauts took to the skies in April last year and returned in November, soon after Dr. Schmid and others were holoportated to the orbiting space laboratory.

A New Resin 3D Printer Combines a CT Scanner and Light to Increase its Speed

At the Technical University of Denmark (DTU), a team of researchers have developed a new kind of 3D printer whose technology combines a CT scanner and light. By reversing the principle of CT scanning, they could create all types of parts in record time from different polymer resins and play on their hardness. They would thus be able to reproduce the appearance of blood vessels or muscle tissue.

Today’s CT scans allow us to make slice images of our body parts and to visualize tissues of different densities. This X-ray machine is therefore used in the medical sector to establish a diagnosis. In this case, it was used to design a new, faster resin 3D printer.

Engineer born with one hand makes a prosthetic one out of plastic bottles for $800

The Force was strong in him. One of Enzo Romero’s favorite activities is playing the guitar, which he effortlessly does with his bright blue hand. Initially, it used to hurt, as he used his handless right arm to press down on chords. But now, with fingers on the end, he can play music painlessly.

Star Wars: Episode V The Empire Strikes Back, marketed as simply The Empire Strikes Back, is a 1980 film directed by Irvin Kershner and written by Leigh Brackett and Lawrence Kasdan from a story by George Lucas. It is the second part of the Star Wars original trilogy.

The film concerns the continuing struggles of the Rebel Alliance against the Galactic Empire. During the film, Han Solo, Chewbacca, and Princess Leia Organa are being pursued across space by Darth Vader and his elite forces. Meanwhile, Luke Skywalker begins his major Jedi training with Yoda, after an instruction from Obi-Wan Kenobi’s spirit. In an emotional and near-fatal confrontation with Vader, Luke is presented with a horrific revelation and must face his destiny.

Though controversial upon release, the film has proved to be the most popular film in the series among fans and critics and is now widely regarded as one of the best sequel films of all time, as well as one of the greatest films of all time. It was re-released with changes in 1997 and on DVD in 2004. The film was re-released on Blu-ray format in September of 2011. A radio adaptation was broadcast on National Public Radio in the U.S.A. in 1983. The film was selected in 2010 to be preserved by the Library of Congress as part of its National Film Registry.

Exploring how fungal infections spread in the human lung

A chip-based infection model developed by researchers in Jena, Germany, enables live microscopic observation of damage to lung tissue caused by the invasive fungal infection aspergillosis. The team developed algorithms to track the spread of fungal hyphae as well as the response of immune cells. The development is based on a “lung-on-chip” model also developed in Jena and can help reduce the number of animal experiments. The results were presented in the journal Biomaterials.

Aspergillosis is a mold infection caused by Aspergillus fumigatus, which often affects the lungs. The disease can be fatal, especially in immunocompromised individuals. In these cases, invasive aspergillosis usually occurs with fungal hyphae invading . So far, there are only a few active substances that can combat such fungal infections. “That’s why it was so important for us to be able to represent this invasive growth in a ,” says Marie von Lilienfeld-Toal, who co-led the study. The internist is a professor at the Department of Internal Medicine II at Jena University Hospital and conducts research at the Leibniz Institute for Natural Product Research and Infection Biology—Hans Knöll Institute (Leibniz-HKI) in Jena, Germany.

The new aspergillosis infection model should help to better observe both the growth of the fungus and the reaction of the immune system and to find possible new approaches for therapies. In addition, new active substances can be tested. The expertise for this is available in Jena: Organ chips have long been developed at the university hospital. The startup Dynamic42, which manufactures the lung chips used in the study, was founded there. First author Mai Hoang also joined the company after completing her doctorate.

Rotating blue laser light reveals unimagined dynamics in living cells

When cities transform into a colorful world of lights as darkness falls, it’s often only possible to estimate their contours, which depending on the perspective can draw the attention to key details or trivia. In fluorescence microscopy, biological cells are marked with fluorescent dyes and excited to luminesce in specific areas by optical switches– like a city at night. However, this light is usually too faint for small, rapid objects, or even goes out after a while. This is known as fluorescence bleaching.

Now, a new approach developed by Prof. Dr. Alexander Rohrbach and his team in the Laboratory for Bio-and Nano-Photonics at the University of Freiburg has found a way to make the smallest objects clearly visible without fluorescence. In this way, cellular structures or virus-sized particles can be observed 100 to 1,000 times longer, ten to 100-times faster and with almost doubled resolution than with . While fluorescence microscopy records what you might call “night-time images” of structures, ROCS microscopy takes “day-time images”—opposites that can complement each other excellently. Rohrbach and his colleagues describe various applications of the technology in the latest issue of Nature Communications.

Mystery of why humans die around 80 may finally be solved

Very good news, if unsurprising.

We already have multiple viable avenues of reducing — or eliminating altogether — this particularly pernicious form of remorseless biological entropy.

So good news… UNLESS you’re one of those people who think death is what MAKES life somehow MEANINGFUL, or that living for thousands of years or more would be BORING.

I — incase you haven’t noticed — am NOT one of those people! 😉👈

The mystery of why humans die at around 80, while other mammals live far shorter or longer lives, may finally have been solved by scientists.

Humans and animals die after amassing a similar number of genetic mutations, researchers have found, suggesting the speed of DNA errors is critical in determining the lifespan of a species.

This Temporary Tattoo Can Monitor Diabetics’ Glucose Levels as Accurately as a Finger Prick

Circa 2015

Engineers from the University of California, San Diego have developed an ultra-thin temporary tattoo that can painlessly and accurately monitor the glucose levels of diabetics.

The flexible device costs just a few cents and lasts for a day at a time, and early tests have shown that it’s just as sensitive as a finger-prick test.

But even cooler is the fact that the system works without blood, by extracting and measuring the glucose from the fluid in between skin cells, and could eventually be adapted to detect other important metabolites in the body, or deliver medicine.

California start-up sending tiny robots on fantastic voyage into brains

Sending miniature robots deep inside the human skull to treat brain disorders has long been the stuff of science fiction—but it could soon become reality, according to a California start-up.

Bionaut Labs plans its first on humans in just two years for its tiny injectable robots, which can be carefully guided through the using magnets.

“The idea of the micro robot came about way before I was born,” said co-founder and CEO Michael Shpigelmacher.
