A dazzling new animation puts you aboard NASA’s robotic Juno spacecraft during its epic flybys last month of Jupiter and the huge moon Ganymede.
On June 7, Juno zoomed within just 645 miles (1038 kilometers) of Ganymede, the largest moon in the solar system. It was the closest a probe had gotten to the icy, heavily cratered world since May 2000, when NASA’s Galileo spacecraft flew by at a distance of about 620 miles (1000 km).
“The American Contractor Show” has shared its review of the installation of a Tesla Solar Roof. The show is a series of episodes featuring contracting and this episode took a deep dive into the Tesla Solar Roof installation process. Davide Silverstein and American Home Contractors demonstrated just what it takes to install a Tesla Solar Roof. The episode includes a step-by-step look at the installation process.
David Silverstein from American Home Contractors takes the host of the American Contractors Show, John Dye, on a walk-through of a Tesla Solar Roof installation.
Ark I is a self-sustaining space colony built to ensure humanity could survive disasters that make Earth uninhabitable such as nanoweapon disasters or particle accelerator mishaps.

Space may be pretty, but it’s dangerous. Astronauts face a much higher dose of ionizing radiation than us Earth-bound folks, and a new report says that NASA’s current guidelines and risk assessment methods are in serious need of an update.
On the surface of the Earth, protected by our extensive magnetic field and layers of thick atmosphere, we experience about 2–3 milliSieverts (mSv) of radiation exposure every year. Even that background level is enough to trigger the occasional cancer growth.
But astronauts, especially those hoping to go on upcoming long-term missions to the Moon and Mars, face a much greater risk due to the high-energy, ionizing radiation constantly soaking every cubic centimeter of space. To mitigate that risk, NASA currently implements a system based on “risk of exposure-induced death” (REID). The space agency estimates the exposure for each astronaut based on their sex, and if the REID exceeds 3%, their spacefaring careers are over.
The world’s first 3D-printed steel bridge has opened in Amsterdam. It was created by robotic arms using welding torches to deposit the structure of the bridge layer-by-layer using 4500 kilograms of stainless steel.
The first ever 3D-printed steel bridge has opened in Amsterdam, the Netherlands. It was created by robotic arms using welding torches to deposit the structure of the bridge layer by layer, and is made of 4500 kilograms of stainless steel.
The 12-metre-long MX3D Bridge was built by four commercially available industrial robots and took six months to print. The structure was transported to its location over the Oudezijds Achterburgwal canal in central Amsterdam last week and is now open to pedestrians and cyclists.
More than a dozen sensors attached to the bridge after the printing was completed will monitor strain, movement, vibration and temperature across the structure as people pass over it and the weather changes. This data will be fed into a digital model of the bridge.
Monstrous AI
Pichai suggests the internet and electricity are also small potatoes compared to AI.
Interested in living longer? You are probably going to get TPE at some point. The Conboys are looking for funding for human trials to produce a product in 3–4 years. Here we have infor on what it is and how it works plus actual human results to date (starting at 10 minutes).
In Part III, Dr Kiprov, discusses the history of moving from the Conboy’s experiments in the lab to the process used in the clinic and reasons for the choices made. He also covers the benefits that he has seen with plasma exchange in the clinic.

Fluorescent sensors glow brightly under UV light if infection starts to set in. Researchers have developed smart wound dressings with built-in nanosensors that glow to alert patients when a wound is not healing properly.
The multifunctional, antimicrobial dressings feature fluorescent sensors that glow brightly under UV light if infection starts to set in and can be used to monitor healing progress.
The smart dressings, developed by a team of scientists and engineers at RMIT University in Melbourne, Australia, harness the powerful antibacterial and antifungal properties of magnesium hydroxide.
As pervasive as they are in everyday uses, like encryption and security, randomly generated digital numbers are seldom truly random.
So far, only bulky, relatively slow quantum random number generators (QRNGs) can achieve levels of randomness on par with the basic laws of quantum physics, but researchers are looking to make these devices faster and more portable.
In Applied Physics Letters, scientists from China present the fastest real-time QRNG to date to make the devices quicker and more portable. The device combines a state-of-the-art photonic integrated chip with optimized real-time postprocessing for extracting randomness from quantum entropy source of vacuum states.
Quantum mechanics deals with the behavior of the Universe at the super-small scale: atoms and subatomic particles that operate in ways that classical physics can’t explain. In order to explore this tension between the quantum and the classical, scientists are attempting to get larger and larger objects to behave in a quantum-like way.
In the case of this particular study, the object in question is a tiny glass nanosphere, 100 nanometers in diameter – about a thousand times smaller than the thickness of a human hair. To our minds that’s very, very small, but in terms of quantum physics, it’s actually rather huge, made up to 10 million atoms.
Pushing such a nanosphere into the realm of quantum mechanics is actually a huge achievement, and yet that’s exactly what physicists have now accomplished.
