Sixty feet beneath the surface of the Caribbean Sea, aquanaut Fabien Cousteau and industrial designer Yves Béhar are envisioning the world’s largest underwater research station and habitat.

The pair have unveiled Fabien Cousteau’s Proteus, a 4,000-square-foot modular lab that will sit under the water off the coast of Curaçao, providing a home to scientists and researchers from across the world studying the ocean — from the effects of climate change and new marine life to medicinal breakthroughs.

Designed as a two-story circular structure grounded to the ocean floor on stilts, Proteus’ protruding pods contain laboratories, personal quarters, medical bays and a moon pool where divers can access the ocean floor. Powered by wind and solar energy, and ocean thermal energy conversion, the structure will also feature the first underwater greenhouse for growing food, as well as a video production facility.

PARIS (Reuters) — A Paris zoo showcased a mysterious new organism on Wednesday, dubbed the “blob”, a yellowish unicellular small living being which looks like a fungus but acts like an animal.

This newest exhibit of the Paris Zoological Park, which goes on display to the public on Saturday, has no mouth, no stomach, no eyes, yet it can detect food and digest it.

The blob also has almost 720 sexes, can move without legs or wings and heals itself in two minutes if cut in half.

Both shocking and intriguing for the possibilities of gynogenesis reproduction in which sperm is used from one creature to fertilize an egg, but its DNA is ignored.

A team of researchers working at Hungary’s National Agricultural Research and Innovation Centre, Research Institute for Fisheries and Aquaculture, has accidentally bred a new kind of fish—dubbed the sturddlefish by some observers, it is a cross between an American Paddlefish and a Russian Sturgeon. In their paper published in the journal Genes, the group describes accidentally breeding the fish and what they learned by doing so.

In the past, scientists and others have bred animals from different species for various reasons, from research to utility—mules (crossed between donkeys and horses) are considered to have beneficial traits from both animals, and ligers (a cross between lions and tigers) have helped researchers understand their respective genetic backgrounds. In this new effort, the researchers claim that they were not trying to create a new type of fish, they were instead attempting to apply gynogenesis (a type of reproduction in which sperm is used from one creature to fertilize an egg, but its DNA is ignored) using American paddlefish and Russian sturgeon. To their surprise, the eggs produced fish that grew to adults.

In studying the hundreds of offspring produced, which some on the internet have named sturddlefish, the researchers found that they fell into one of three main categories: those that looked mostly like their mothers, those that looked mostly like their fathers and those that inherited features of both parents.

Our kidneys are crucial for keeping us alive and healthy. A sort of chemical computer that keeps our blood chemistry stable—whether we’re eating a sugary birthday cake or a vitamin-filled salad—they prevent waste buildup, stabilize our electrolyte levels, and produce hormones to regulate our blood pressure and make red blood cells.

Kidneys clean our blood using nephrons, which are essentially filters that let fluid and waste products through while blocking blood cells, proteins, and minerals. The latter get reintegrated into the blood, and the former leave the body in urine.

Scientists have struggled to come up with viable treatments for kidney disease and renal failure, and their complexity means kidneys are incredibly hard to synthetically recreate; each kidney contains around one million intricately-structured nephrons.

Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed a novel method of using fruit peel waste to extract and reuse precious metals from spent lithium-ion batteries in order to create new batteries.

The team demonstrated their concept using orange peel, which recovered precious metals from battery efficiently. They then made functional batteries from these recovered metals, creating minimal waste in the process.

The scientists say that their waste-to-resource approach tackles both and electronics waste, supporting the development of a circular economy with zero waste, in which resources are kept in use for as long as possible. An estimated 1.3 billion tons of food waste and 50 million tons of e-waste are generated globally each year.

Circa 2011

This gorgeous, stainless steel and bronze toy car is simply named Toy Car, which seems an appropriately stripped-down name for such a minimalist vehicle. Without a body, or even a cover over the engine, you can see exactly how the car works.

It’s essentially a fancy version of the pull-back-and-go cars found in cereal boxes and kids’ fast-food “meals” everywhere. Pull the car backwards while pushing down and the motion of the turning wheels is stored as energy in a coiled spring inside the big central toothed wheel. Let go and it unwinds, propelling the machine forward. When the spring has fully sprung, a clutch disengages and lets the car roll free.

In The Martian, Matt Damon’s character is able to survive being marooned on Mars by growing potatoes in the Martian soil. While fictional, this plot point reflects a real need for in-situ resource utilization (ISRU) to support long-term human space exploration missions. A new study by a team from the Florida Institute of Technology suggests that the Martian soil may be more hostile to plant life than previously thought and that the capability of growing Martian potatoes will require additional development to make agriculture feasible.

The researchers studied three examples of Martian regolith simulants. These simulants are produced from materials found on Earth to reproduce the mineralogy and chemistry of the soil we expect to find on Mars. They found that none of these simulants were able to support plant life on their own, partly due to nitrogen deficiency, and only two were able to do so when nutrient supplements were added. More crucially, none of these simulants could support plant life at all when calcium perchlorate — a common, and toxic, substance on Mars’s surface — was added. Their results suggest that any scheme for ISRU agriculture on the surface of Mars must plan to remediate, or otherwise avoid, the toxic effects of perchlorate before attempting an extraterrestrial harvest.

Innovation is key for developing the future of agriculture and sometimes it comes from unlikely places.

The NASA Artemis Mission is working to develop space exploration, but here on Earth, they are partnering with the University of California Berkeley to use Land Satellite Seven to benefit agriculture.

According to NASA Administrator Jim Bridenstine, “We can use that data from space and combine it with weather stations from Earth, and we can get very precise evapotranspiration measurements, down to a quarter of an acre. What that means is we can provide farmers with very specific irrigation plans.”

The technology is still in the testing phase but could one day make farming a little easier. “Imagine being a farmer and going out into your field with your iPhone, looking at it and having an app on there that tells you exactly what your irrigation needs to be for this quarter of an acre for this type of soil and this type of crop,” Bridenstine states.

NASA looks to partner with private businesses to bring new technologies to the market. “The challenge is land sat only has a revisit of two weeks,” he notes. “Weather changes a lot in two weeks; so, I think there is a future where a commercial company could create lots of satellites that could provide this data to farmers.”
