2023-08-03 10:10:47 Kirigami-inspired robotic grippers combine strength & a delicate touch

Using a novel design inspired by the Japanese art of paper cutting, researchers have developed gentle yet strong robotic grippers that can fold clothes, grasp a drop of water and ultrathin microfibers, lift 16,000 times their own weight, and turn the pages of a book. The device has a wide range of potential applications, from prosthetics to minimally invasive surgery and deep-sea exploration. Open / Comment

2023-08-03 09:39:43 Superconductor Breakthrough Findings Replicated, Twice, in Preliminary Testing

Humanity may be in the throes of another breakthrough that's every bit as impactful as the invention of the transistor and the advent (and eventual vindication) of quantum computing. LK-99, as it's been named, is a new compound that researchers believe will enable the fabrication of room-temperature, ambient-pressure superconductors. Initially published by a Korean team last Friday, frantic work is underway throughout the research world to validate the paper's claims. For now, two separate sources have already provided preliminary confirmations that this might actually be the real thing — Chinese researchers have even posted video proof. Strap in; this is a maglev-powered, superconducting ride. Open / Comment

2023-07-21 09:30:23 Exploring the Fascinating World of Material Science!

Hey everyone! Let's dive into an intriguing experiment carried out by comrades from Sandia National Laboratories and Texas A&M University! During their working hours, they decided to have some fun with a tiny 40-nanometer piece of platinum, levitating it in a vacuum and stretching it in various directions with a frequency of 200 vibrations per second.

Now, here comes the exciting part! Instead of the expected microscopic fractures and cracks due to "fatigue stress," something extraordinary happened - the cracks started to heal themselves!

Isn't that incredible? The secret lies in the metal atoms' ability to interact and bond when they are in close proximity to each other, a phenomenon unhindered by air molecules in the vacuum.

This discovery could lead us to rethink aircraft construction. Imagine airplanes made from metals, rather than composites, with special vacuum barocamera treatment to combat structural fatigue!

The world of science never fails to amaze us! Let's keep exploring, learning, and pushing the boundaries of knowledge!

2023-07-21 09:10:37 The Moon harbors the largest amount of human debris artifacts, undoubtedly. At the landing sites of various Apollo missions, numerous items left behind by astronauts during their expeditions can be found. For instance, the crew of Apollo 15 erected a memorial to honor the fallen space pioneers, while Astronaut Charles Duke placed a photograph of his family on the lunar surface. Additionally, Eugene Cernan left a video camera to allow future scientists to study the impact of radiation on its lens.

However, among these artifacts, two golf balls stand out as the most peculiar. These golf balls were carried to the Moon by the commander of the Apollo 14 mission, Alan Shepard. During one of the surface trips, Shepard took the opportunity to play golf using a modified club, though he later faced criticism for engaging in leisure activities during an important mission. Shepard himself asserted that one of the balls, after being struck by the club, traveled for kilometers, almost reaching outer space. Subsequently, it was revealed that the story had been embellished, as the balls only flew a few dozen meters.
