Printed robots with bones, ligaments, and tendons      (via sciencedaily.com)     Original source 

For the first time, researchers have succeeded in printing a robotic hand with bones, ligaments and tendons made of different polymers using a new laser scanning technique. The new technology makes it possible to 3D print special plastics with elastic qualities in one go. This opens up completely new possibilities for the production of soft robotic structures.

James Webb Space Telescope detects water vapor, sulfur dioxide and sand clouds in the atmosphere of a nearby exoplanet      (via sciencedaily.com)     Original source 

Astronomers have used recent observations made with the James Webb Space Telescope to study the atmosphere of the nearby exoplanet WASP-107b. Peering deep into the fluffy atmosphere of WASP-107b they discovered not only water vapor and sulfur dioxide, but even silicate sand clouds. These particles reside within a dynamic atmosphere that exhibits vigorous transport of material.

Galactic 'lightsabers': Answering longstanding questions about jets from black holes      (via sciencedaily.com)     Original source 

The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them. Almost everything, it turns out. Astrophysicists have now determined conclusively that energy close to the event horizon of black hole M87* is pushing outward, not inward. The researchers have also created a way to test the prediction that black holes lose rotational energy and to establish it's that energy that produces the incredibly powerful jets.

Tracking down quantum flickering of the vacuum      (via sciencedaily.com)     Original source 

Absolutely empty -- that is how most of us envision the vacuum. Yet, in reality, it is filled with an energetic flickering: the quantum fluctuations. Experts are currently preparing a laser experiment intended to verify these vacuum fluctuations in a novel way, which could potentially provide clues to new laws in physics. A research team has developed a series of proposals designed to help conduct the experiment more effectively -- thus increasing the chances of success.

Device 'smells' seawater to discover, detect novel molecules      (via sciencedaily.com)     Original source 

Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.

Black holes are messy eaters      (via sciencedaily.com)     Original source 

New observations down to light-year scale of the gas flows around a supermassive black hole have successfully detected dense gas inflows and shown that only a small portion (about 3 percent) of the gas flowing towards the black hole is eaten by the black hole. The remainder is ejected and recycled back into the host galaxy.
