An international team of scientists has developed a soft robotic sleeve that can be implanted on the external surface of the heart to restore blood circulation in pigs (and possibly humans in the future) whose hearts have stopped beating.

The device is a silicone-based system with two layers of actuators: one that squeezes circumferentially and one that squeezes diagonally, both designed to mimic the movement of healthy hearts when they beat.

Our home galaxy, the Milky Way, is being pushed across the universe by a large unseen force, according to new research. Although it may not seem like a friendly gesture, the newly discovered Dipole Repeller is actually helping our galaxy on its journey across the expanding universe.

Researchers have known that the galaxy was moving at a relative speed for the past 30 years, but they didn’t know why.

“Now we find an emptiness in exactly the opposite direction, which provides a ‘push’ in the sense of a lack of pull,” said Brent Tully, one of the study authors and an astronomer at the Institute for Astronomy in Honolulu. “In a tug-of-war, if there are more people at one end, then the flow will be toward them and away from the weaker side.”

Obviously this “quadcopter” is a demonstration device, showing how moving magnets over a conducting surface can generate levitation. It has not been optimized to minimize losses or be an efficient mode of transport. I still think it’s pretty cool. I’m used to seeing light things levitated by induced currents but not a 100+ lb machine.

In the hope of creating a ‘human-AI’ cyborgs, Elon Musk has revealed that Tesla may be working on computers that can be implanted into people’s brains.

The astonishing revelation came in response to a tweet, asking Musk if he was working on ‘neural lace’ – a way of installing computers into the human brain.

It is not known what the brain chip could be used for, but Musk has previously said that it will be the ‘thing that really matters for humanity to achieve symbiosis with machines.’

Arizona State University (ASU) is developing a small satellite that will search hydrogen in lunar craters with the ultimate goal of creating the most detailed map of the moon’s water deposits. The spacecraft, named Lunar Polar Hydrogen Mapper (LunaH-Map), is expected to shed new light on the depth and distribution of water-ice on the moon.

In Brief

  • Czech scientists have developed a 3D printed model of a functioning lung that can simulate real-life conditions like asthma and other chronic breathing problems.
  • Their model could lead to new treatment options for those suffering from chronic obstructive pulmonary diseases, which claim more than 3 million lives every year.

3D printing is opening so many new doors in the medical field. The technology allows researchers and doctors to manipulate the finest design nuances of models as well as the properties of the materials used to build them. These 3D printed models of organs, bones, and other organic subjects are valuable tools for both students learning the basics and medical experts testing new treatments and conducting experimental research.

Now, Czech scientists from the Brno University of Technology have developed a 3D printed model of a functioning lung that can simulate real-life conditions like asthma and other chronic breathing problems. They believe that their 3D printed mechanical model and its computer-based counterpart can be used to devise new, more precise treatment methods. It would be particularly useful in creating a reference standard for inhaled drugs. “This model will show whether an inhaled drug will settle in the concrete areas where we need it to,” Miroslav Jicha, the head of the research team, told Reuters.

Last year, a Made In Space-led team achieved something that had never been accomplished. For the first time in history, a commercial in-space manufacturing facility began operation aboard the International Space Station (ISS). While private parties are able to commission objects to be built by Made In Space’s Additive Manufacturing Facility (AMF) on orbit, the hardy device also supports astronauts by manufacturing parts, tools, and supplies that can be used on the ISS.

Made In Space has continued its mission to enable humans to live and work in space by demonstrating several new technologies in microgravity. Testing machines on Earth that are optimized to work in environments which have little or no gravity can be difficult at the bottom of Earth’s gravity well. The Flight Opportunities Program (FOP) at Johnson Space Center in Houston, Texas utilizes high-tech aircraft to fly in aggressive parabolic arcsa nose dive followed by a sharp ascent. This maneuver creates a gravity-free environment within the plane’s cabin for less than a minute before having to pull up and repeat. After partaking in over 200 of these parabolic flights, MIS has demonstrated several manufacturing techniques in microgravity that will be critical to the success of our journeys to other planets.
