Humanoid robots may enhance growth of musculoskeletal tissue grafts for tissue transplant applications.

Over the past decade, exciting progress has been made in the development of humanoid robots. The significant potential future value of humanoids includes applications ranging from personal assistance to medicine and space exploration. In particular, musculoskeletal humanoids (such as Kenshiro and Eccerobot) were developed to interact with humans in a safer and more natural way (1, 2). They aim to closely replicate the detailed anatomy of the human musculoskeletal system including muscles, tendons, and bones.

With their structures activated by artificial muscles, musculoskeletal humanoids have the ability to mimic more accurately the multiple degrees of freedom and the normal range of forces observed in human joints. As a result, it is not surprising that they offer new opportunities in science and medicine. Here, we suggest that musculoskeletal robots may assist in the growth of musculoskeletal tissue grafts for tissue transplant applications.

SpaceX’s announcement that they will launch two tourists on a trip around the moon has captured imaginations with renewed speculation about the future of space travel and accessibility to the beyond.

“We are excited to announce that SpaceX has been approached to fly two private citizens on a trip around the moon late next year. They have already paid a significant deposit to do a moon mission,” Musk wrote in their announcement. “Like the Apollo astronauts before them, these individuals will travel into space carrying the hopes and dreams of all humankind, driven by the universal human spirit of exploration.”

However, it really is not fair to a number of other companies that are revolutionizing space travel all the same but don’t have the substantial resources or notoriety of Elon Musk’s gargantuan company. Musk’s celebrity status makes his every tweet a news story (not totally unlike, but in many ways extremely unlike, the newest US president). With that sort of figure, it is hard to capture people’s attention if you are running one of SpaceX’s “pretenders” and competitors. The Hawthorne, Cali company not only operates its own mission services using rockets it built itself, but also sells those rockets to other launch providers.

In Brief

  • Yesterday, SpaceX founder and CEO Elon Musk said that his private spaceflight company would have a notable announcement today at 4pm EST (1pm GMT).
  • It seems that humans are going back to the Moon. Here’s what you need to know about this new revelation and what it means in relation to humanity’s journey into the cosmos.

Rocket science isn’t easy. Ask any engineer. Rocket science isn’t cheap. Just ask NASA. Fortunately, in recent years, a number of commercial spaceflight companies have stepped up to the plate in order to help national space agencies extend their reach into the final frontier.

Innovative companies like Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin have accelerated the development of reusable rockets exponentially. In so doing, they have dramatically reduced the cost of leaving our pale blue dot, improving both our ability to explore the cosmos and scientists’ capacity to conduct research beyond Earth.

NASA’s Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

Gamma rays are the highest-energy form of light, produced by the universe’s most energetic phenomena. They’re common in galaxies like the Milky Way because , particles moving near the speed of light, produce when they interact with and starlight.

Surprisingly, the latest Fermi data shows the gamma rays in Andromeda—also known as M31—are confined to the galaxy’s center instead of spread throughout. To explain this unusual distribution, scientists are proposing that the emission may come from several undetermined sources. One of them could be , an unknown substance that makes up most of the universe.

Well I for one would be in the 6%.

A new survey has found that only 6% of respondents would be happy to live in a proposed Equatorial Low Earth Orbit (ELEO) settlement, where humans live in a small cruise ship-like space station at a similar orbit to the ISS.

Four conditions were set for respondents to assess and while at least 30% said they agree with at least one of them, the number shrank significantly when it came to those who could accept all the conditions.

These were that the settlement itself would require permanent residence, would be no bigger than a large cruise ship, would contain no more than 500 people and would require residents to be willing to devote at least 75% of their wealth to move in.

Space suits are iconic—a visual metaphor for the excitement of the original Space Race and mankind’s first forays off our planet. While many still associate space travel with the puffy white suits worn by astronauts in the 1960s, a proliferation of sci-fi movies in the intervening decades has opened our imaginations to a wider array of possibilities. Far from being fantastical, these new spacesuits reflect an evolved understanding of the considerations involved in protecting the human body from harsh environments outside Earth’s atmosphere.
