The new system uses molten salts instead of traditional fuel rods.

The world is rethinking nuclear power plants in the face of climate change. Your average plant produces 8,000 times more power than fossil fuels and is environmentally friendly. There’s one massive caveat, though, in the form of nuclear disasters, such as the 1986 Chernobyl incident and the 2011 Fukushima disaster.

Now, professor Matthew Memmott and colleagues from Bingham Young University (BYU) announced that they designed a new molten salt micro-reactor system that allows for safer nuclear energy production. As per a press release, it may also solve a number of other key issues related to nuclear energy production.

The 40-square-meter hydroponic farm cultivates lettuce under LED lighting without using pesticides.

In an effort to provide passengers with amenities beyond transportation, Taiwan has chosen an unusual location for vertical farming, an underground metro station.

Nanjing Fuxing station in Taipei cultivates vegetables in a technologically advanced setting that assures precisely controlled humidity, temperatures, and other elements promoted as a method of cultivating unpolluted and healthy plants, Taiwan News reported on Wednesday.

The massive launch system will carry a mysterious U.S. Space Force payload to a high-altitude geosynchronous orbit.

It’s been a while since SpaceX launched Falcon Heavy to orbit. A string of payload delays has stopped the heavy-duty rocket from hitting the launch pad since the summer of 2019.

This could help us understand diseases better.

Researchers at the University of Utah have developed seed-sized brain organoids that can not only organize themselves but also provide us insights into the causes of autism, a press release said.

Organoids, tiny clusters of tissue derived from stem cells, allow researchers to replicate the complex organs outside the body while also controlling conditions around them… More.

Fiction will become reality at the 2022 Monaco Yacht Show.

Dutch yacht builder U-Boat Worx has unveiled the design of its $25 million superyacht, Nautilus.

More than 150 years ago, Jules Verne’s 20,000 Leagues Under the Sea first brought to our attention the possibility of a luxury yacht that could take an underwater dip at will. Over the years, the concept has been admired and looked up to by many engineers but building a real-world prototype has so far still been a dream.

Discarded electronic devices, such as cell phones, are a fast-growing source of waste. One way to mitigate the problem could be to use components that are made with renewable resources and that are easy to dispose of responsibly. Now, researchers reporting in ACS Applied Materials & Interfaces have created a prototype circuit board that is made of a sheet paper with fully integrated electrical components, and that can be burned or left to degrade.

Most small electronic devices contain circuit boards that are made from glass fibers, resins and metal wiring. These boards are not easy to recycle and are relatively bulky, making them undesirable for use in point-of-care medical devices, environmental monitors or personal wearable devices.

One alternative is to use paper-based circuit boards, which should be easier to dispose of, less expensive and more flexible. However, current options require specialized paper, or they simply have traditional metal circuitry components mounted onto a sheet of paper. Instead, Choi and colleagues wanted to develop circuitry that would be simple to manufacture and that had all the electronic components fully integrated into the sheet.

Tiny particles are interconnected despite sometimes being thousands of kilometers apart—Albert Einstein called this “spooky action at a distance.” Something that would be inexplicable by the laws of classical physics is a fundamental part of quantum physics. Entanglement like this can occur between multiple quantum particles, meaning that certain properties of the particles are intimately linked with each other.

Entangled systems containing multiple quantum particles offer significant benefits in implementing quantum algorithms, which have the potential to be used in communications, data security or quantum computing. Researchers from Paderborn University have been working with colleagues from Ulm University to develop the first programmable optical quantum memory. The study was published as an “Editor’s suggestion” in the Physical Review Letters journal.

The Florida Institute for Human & Machine Cognition (IHMC) is well known in bipedal robotics circles for teaching very complex humanoid robots to walk. Since 2015, IHMC has been home to a Boston Dynamics Atlas (the DRC version) as well as a NASA Valkyrie, and significant progress has been made on advancing these platforms toward reliable mobility and manipulation. But fundamentally, we’re talking about some very old hardware here. And there just aren’t a lot of good replacement options (available to researchers, anyway) when it comes to humanoids with human-comparable strength, speed, and flexibility.

Several years ago, IHMC decided that it was high time to build their own robot from scratch, and in 2019, we saw some very cool plastic concepts of Nadia —a humanoid designed from the ground up to perform useful tasks at human speed in human environments. After 16 (!) experimental plastic versions, Nadia is now a real robot, and it already looks pretty impressive.
