Tiny nanobots made of frog cells might prevent your next heart attack – BGR
It won’t be long until we start sending fleets of tiny nanobots inside our bodies to deliver medicine and fix a few of the annoying problems that might otherwise cause irreparable harm and even death. But those robots might not have any metallic components if some researchers have their way. Instead, these fleets of robots capable of traveling through our bodies might be made of something entirely unexpected: Frog cells.
Called xenobots — after the African clawed frog Xenopus laevis — these tiny creatures are made by both man and machine from stem cells. And once inside the human body, they may be able to unclog arteries and prevent that imminent heart attack the doctor has warned you about.
It might be years of research before that happens, but the Universities of Vermont and Tufts have been able to generate these “entirely new life-forms.” Created from frog stem cells, the xenobots are less than a millimeter (0.04 inches) wide, and travel inside blood vessels. They can walk and swim, CNN reports, and they can work alone and in groups.
The stem cells were cut and reshaped into specific body forms to help with a certain task, with a computer helping humans playing god. These supercomputers made beings unseen in nature, the University of Vermont said. The bio-robots have skin and a heart muscle that lets them move around. They can self-heal if needed, and they can feed on certain nutrients and survive inside the host as long as there’s a specific source of food available.
“These are novel living machines,” University of Vermont computer scientist and robotics expert Joshua Bongard said. “They’re neither a traditional robot nor a known species of animal. It’s a new class of artifact: a living, programmable organism.”
These xenobots could have uses in various fields, not just medicine. They could be used to access radioactive areas and clean them up and collect microplastics in oceans. And once they run out of the preloaded lipid and protein food, they’ll just self-destroy without leaving any waste behind. Or, at least, not the kind that you’d associate with nanorobots made of non-biological material.
The theoretical medical uses are more exciting, of course. Aside from unclogging coronary arteries, the robots could be used to explore other conditions. “If we could make 3D biological form on demand, we could repair birth defects, reprogram tumors into normal tissue, regenerate after traumatic injury or degenerative disease, and defeat aging,” the researcher said in an FAQ.
The research was partially funded by the Defense Advanced Research Projects Agency, but that doesn’t mean these xenobots could be weaponized with the help of AI. At least, the researchers say it would be no easy task. “At the moment, though, it is difficult to see how an AI could create harmful organisms any easier than a talented biologist with bad intentions could,” they wrote in the same FAQ. “Despite this, we believe that, as this technology matures, regulation of its use and misuse should be a high priority. Again though, the possibility of misuse is much, much smaller than what is being done with self-reproducing agents like bacteria, viruses, and gene drives.”
How to watch the Axiom-2 mission depart from the ISS on Tuesday – Digital Trends
This Tuesday, the crew of the second-ever all-private mission to the International Space Station will be returning to Earth. The Axiom 2 or Ax-2 mission launched last week and saw private astronauts Peggy Whitson, John Shoffner, Ali Alqarni, and Rayyanah Barnawi traveling to the ISS on a SpaceX Crew Dragon launched from the Kennedy Space Center in Florida.
Now, the crew of four will be traveling back to Earth in the same Crew Dragon, and NASA will be livestreaming the departure of the spacecraft from the station. A separate stream will also be available showing the Crew Dragon splashing down off the coast of Florida. We’ve got the details on how to watch both below.
How to watch the mission departure
Coverage of the departure of the Crew Dragon from the ISS will begin at 9 a.m. ET (6 a.m. PT) on Tuesday, May 30. NASA will show a short introduction before the closing of the hatch of the station’s Harmony module at 9:10 a.m. ET (6:10 a.m. PT). There will then be a short break in coverage, which will resume at 10:45 a.m. ET (7:45 a.m. PT) to show the undocking of the Dragon at 11:05 a.m. ET (8:05 a.m. PT), with coverage ending 30 minutes after undocking.
You can watch the livestream of the hatch closing and the undocking on NASA’s YouTube channel, or by using the video embedded near the top of this page.
The crew will then travel back to Earth throughout Tuesday and into Wednesday, May 31. When the Crew Dragon is approaching Earth for splashdown, you’ll be able to tune into a livestream from Axiom Space. That will be available on Axiom’s website, but the company has not yet confirmed the exact time that coverage is expected to begin on Wednesday. You can find the latest updates on Axiom Twitter.
What to expect from the mission departure
The Ax-2 crew will have spent 10 days in space before heading home, and they will be bringing around 300 pounds of cargo back with them. The mission is notable for including the first two astronauts from Saudi Arabia, Ali Alqarni and Rayyanah Barnawi, as well as famous American astronaut Peggy Whitson who has spent more days in space than any other American or any other woman.
Axiom Space launched its first private mission to the ISS in April last year, with a third mission planned for November this year and a fourth planned for 2024.
NASA's New Horizons Spacecraft Captures ''Heart-Shaped'' Glacier On Pluto's Surface – NDTV
Space agency NASA routinely captures stunning images of our universe, leaving space lovers mesmerized. On Sunday, NASA shared a stunning image on Instagram taken by its New Horizons spacecraft showing a heart-shaped glacier on Pluto’s surface. The heart-shaped region is known unofficially as Tombaugh Regio and is made of nitrogen and methane.
The image was captioned as ”Absence makes the heart grow fonder. Our New Horizons spacecraft captured this heart-shaped glacier. It lies on Pluto’s surface, which also features mountains, cliffs, valleys, craters, and plains, thought to be made of methane and nitrogen ice ”
See the image here:
It described the image as ”Pluto’s surface is marked with cracks and craters in shades of brown. The partially visible heart appears in the lower right of the small world, which is surrounded by black space.”
New Horizons launched in January 2006 and reached Pluto in July 2015, flying within 7,800 miles of its surface, and becoming the first probe to fly by Pluto and its moons. The far-traveling spacecraft also visited a distant Kuiper Belt object Ultima Thule (2014 MU69) in January 2019.
Instagram users loved the picture and shared a variety of comments. One user wrote, ”Wouahh what a great capture, thanks to New Horizon spacecraft.” Another commented, ”For me, Pluto will always be a planet.”
A third said, ”Why is Pluto, not a plane? it literally has a heart!” A fourth added, ”Being afar doesn’t mean you aren’t part of the family.”
Pluto was once considered the ninth planet in the solar system, however, it was demoted in 2006 and reclassified as a dwarf planet. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet.
Pluto is slightly over 1,400 miles (2250 km) wide or about half the breadth of the United States or two-thirds the width of the Moon. With its average temperature of -387F (-232C) – Pluto’s surface is coated in ice made of water, methane, and nitrogen and is believed to have a rocky core and possibly a deep ocean.

Final Pair of Storm-Observing CubeSats Launched
The final two CubeSats for NASA’s TROPICS mission launched from Rocket Lab’s Launch Complex 1 in New Zealand on May 26. The small satellites will join two other identical spacecraft that launched to orbit earlier this month.
All four will fly, as a constellation, in a unique low Earth orbit that will allow them to observe tropical cyclones, including hurricanes and typhoons, more often than what is possible with
current weather satellites.
Autonomous Snake-Like Robotic Explorer
A team at NASA’s Jet Propulsion Laboratory is creating and testing a snake-like robot called EELS, short for Exobiology Extant Life Surveyor. The self-propelled, autonomous robot is
being developed to go where other robots can’t go.
Although it was inspired by a desire to look for signs of life in the sub-surface ocean on <span class="glossaryLink" aria-describedby="tt" data-cmtooltip="
