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.

🔬 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! 🚀🔍

3D-printed bend-based frictionless gear mechanism for precise rotation


It might look like some bizarre alien artwork but this is actually a frictionless gear mechanism, 3D printed all in one in high performance stainless steel, designed to enable the precise rotation of items such as satellite thrusters, sensors, telescope lenses or mirrors.

Standard moving parts in space involve friction, and therefore require some kind of lubrication that can potentially lead to unwanted contamination of delicate systems, while also inducing ongoing wear and tear. By contrast, this is an example of a "compliant mechanism" that transmit force through bending, or "elastic deformation," such as bag fasteners or bows and arrows.
Incorporating 24 bendable blades, of which 16 are interlocking, the design serves to
reduce the turning force induced upon it by a factor of 10, to allow very fine control of
rotary motion.

AI can track human movement by utilizing only WiFi routers to "perceive" through walls. Yes, you read that correctly.

▶️ Three researchers employed three affordable consumer routers and receivers, without the use of LiDAR.
▶️ This development was carried out by Meta AI researchers with external assistance.
▶️ They utilized a system called "DensePose" to map around two dozen points and areas on human bodies.
▶️ By combining this data with a neural network, they successfully used WiFi signals to generate the images depicted below.

This breakthrough implies that WiFi can be employed to "see through" materials such as drywall, fences, concrete, and more.

Back in 2018, MIT employed similar technology to visualize people as stick figures through walls, but this is the first time such a level of detail, complete with wireframes, has been achieved.

NASA Researchers Detect Tsunamis by Their Rumble in the Atmosphere

NASA's Jet Propulsion Laboratory (JPL) is testing a novel approach to detect tsunamis from the far reaches of the atmosphere using a new hazard-monitoring technology called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network). This experimental system utilizes data from clusters of GPS and other navigational satellites, collectively known as global navigational satellite systems (GNSS), to detect the ocean's deadliest waves. The technology works by monitoring the disturbances in the ionosphere caused by tsunamis, which can distort the signals from nearby navigational satellites. The system is still in development but has already shown promise as one of the fastest monitoring tools of its kind, potentially providing up to an hour of warning depending on the distance of the tsunami origin from the shore.

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.

Remembering August 9, 1945: The US Atomic Bombing of Nagasaki

Today marks the anniversary of a momentous and somber event in world history. On this day in 1945, the United States dropped an atomic bomb on the city of Nagasaki, Japan, just three days after the bombing of Hiroshima. These bombings brought about the end of World War II, but they also resulted in the loss of tens of thousands of lives and left lasting scars on the survivors and the cities themselves.

As we reflect on this day, it's essential to remember the human cost of war and the profound impact of nuclear weapons. The survivors, known as Hibakusha, have shared their harrowing stories with the world, reminding us of the devastating effects of nuclear warfare and the importance of working towards a world free of nuclear weapons.

The bombings of Hiroshima and Nagasaki serve as a stark reminder of the consequences of global conflict and the responsibility we all share in promoting peace and understanding. Today, as we commemorate this tragic event, let us recommit ourselves to the pursuit of a more peaceful, just, and interconnected world.

We honor the memory of those who lost their lives and stand in solidarity with the survivors and their descendants. May their stories inspire us to work towards a future where such atrocities are never repeated.
