There are many parts of the world which lack infrastructure, but that get a lot of sunlight … which makes buildings uncomfortably hot. A new system could help, as it uses a combination of sunlight and salt water – but no electricity – to produce a cooling effect.

Currently being developed at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST), the experimental setup takes advantage of a natural “phase-change” phenomenon in which energy is absorbed as salt crystals dissolve within water. This means that if salt is added to warm water, that water rapidly cools as the salt dissolves.

After some experimentation with different types of salt, it was found that one known as ammonium nitrate worked best. Mainly because it’s highly water-soluble, its cooling power is four times greater than that of the next-best salt, ammonium chloride. As an added bonus, ammonium nitrate is already widely utilized in fertilizer, and is quite inexpensive.

Protons populate the nucleus of every atom in the universe. Inside the nucleus, they cling tightly to neighboring protons and neutrons. However, it may be possible to knock out protons that are in a smaller size configuration, so that they interact less with nearby particles as they exit the nucleus. This phenomenon is called color transparency. Nuclear physicists hunting for signs of color transparency in protons recently came up empty handed.

The Impact.

The theory that describes the behavior of particles made of quarks is called quantum chromodynamics (QCD). QCD includes many common subatomic particles, such as protons and neutrons. It also predicts the phenomenon of color transparency. Physicists have observed color transparency in simpler, two-quark particles called pions. If physicists can observe or rule out color transparency for protons, a more complicated three-quark system, they would gain important clues regarding the differences between two-and three-quark systems in QCD.

A quantum computer made by researchers in China has solved a calculation in 4.2 hours that would take a classical computer thousands of years. This demonstration of what the researchers call “quantum computational advantage” was made using 6 more qubits – quantum bits – than the computer used by the Google team that first demonstrated the feat in 2019.

Maybe try a 100 percent recycling rate for sewage and chemical extraction.

As if going to the bathroom in microgravity wasn’t complicated enough.

It sounds as though the four space tourists on SpaceX’s historic Inspiration4 flight last week had a bit of a smelly mishap. The Waste Management System experienced an “anomaly” — that’s code of “uh oh” in space jargon — with its suction fan causing the crew to struggle with doing their business while floating hundreds of miles above the surface.

Musk also promised a number of improvements for the next all-civilian space tourism flight. “Definitely upgraded toilets,” Musk responded to another Twitter account suggesting heated toilet seats. “We had some challenges with it this flight.”

Alphabet’s floating internet venture Project Loon may have been deflated, but its legacy looks set to live on through a new effort called Project Taara. The team has salvaged the technology to deliver internet connectivity with lasers, demonstrating the viability in a new test between two cities separated by the Congo River.

Originally a Google side hustle before being spun off into its own project by parent company Alphabet, Project Loon had lofty goals of connecting remote regions to the internet by beaming lasers between high-altitude balloons. After years of successful trials however, the project was eventually grounded in January 2021 due to sky-high costs.

The balloons may have been a bust, but there’s still life in the lasers. After all, wireless optical communication systems could help connect communities where it’s not feasible to build complex grids of underground optical fiber cables, and where cellular or satellite internet is patchy or expensive.
