Up, up, and away!
Four astronauts went to space on November 10 as part of NASA’s Commercial Crew Program. Their destination is the ISS, where they’ll stay until 2022.
Scientists created an intelligent material that acts as a brain by physically changing when it learns. This is an important step toward a new generation of computers that could dramatically increase computing power while using less energy.
Artificial intelligence imitates human intelligence by recognizing patterns and learning new things. Currently, it is run on machine learning software. But the “smarter” computers get, the more computing power they require. This can lead to a sizable energy footprint, which could destabilize the computer.
In the last seven years, computer usage has increased by 300,000-fold. Since 2012 the amount of computing power used to train the largest AI models has doubled every 3.4 months, the MIT Technology Review reports. And, the escalating costs of deep learning, can have environmental costs too. Researchers at the University of Massachusetts, Amherst, found that a common large AI model emits more than 626,000 pounds of carbon dioxide in its lifetime, nearly five times that of the average American car.
The nutrient content of our vegetables is down 40% over the last two decades and our soil health is suffering due to increasingly harsh herbicide use, according to Carbon Robotics founder Paul Mikesell. And farmers are increasingly concerned about the long-term health impacts of continually spraying chemicals on their fields.
But not weeding will cost half your crop, killing profitability.
The solution?
Einride estimates its autonomous pods will save GE around 970 tons of carbon dioxide emissions in the first year, with that number increasing over time.

Up next ►► Vertical farms could take over the world https://youtu.be/J4SaSfnHK3I Instead of shipping food all around the world, imagine your own food coming from your farm in a shipping container, just outside your backdoor. That’s the vision of FarmPod, a St. Croix-based startup looking to completely redefine our relationship with food with a fully automated vertical aquaponic system. This self-contained, solar powered farming method uses a fraction of the water and space of a traditional farm, and even uses zero pesticides. The closed loop system essentially mimics nature’s ecosystems, like a pond. Lettuce, strawberries, kale, collard greens and more can grow in the pod. And, since the produce doesn’t need to be picked early to be shipped to a grocery store, the owner can enjoy their harvest at its peak nutritional value and taste. Produce isn’t all — FarmPod can provide an aquaponic home for tilapia, catfish, crayfish, koi, and freshwater prawns. FarmPod uses automated software and hardware to make their pod’s aquaponics system as easy to run as possible. Mike Straight, the creator and CEO of FarmPod, wants to provide a healthy, hyper-localized source of food with a minimal carbon footprint. “We’re trying to feed the world one pod at a time by hyper-localizing farming, and taking the farm and putting it right in front of the place that needs to use it,” says Straight.

A new type of plastic can rapidly heal itself under water, even in harsh conditions. It maintains its strength after self-healing, so it may be useful in emergencies at sea.
Lili Chen at Tsinghua University in China and her colleagues developed this material, called Rapid Underwater Self-healing Stiff Elastomer (RUSSE) because most self-healing polymers don’t work very well under water. “Room temperature self-healing polymers generally have a poor underwater stability, low healing strength and a slow healing process,” says Chen.

A team of researchers from Worcester Polytechnic Institute, Woods Hole Oceanographic Institution and Harvard University believes that the plastic amassing in floating islands in the oceans could be used to power the ships that are sent to clean them up. In their paper published in Proceedings of the National Academy of Sciences, the group describes how ocean plastics could be converted to ship fuel.
Prior research has shown that millions of tons of plastics enter the ocean each year—some of it is ground into fragments and disperses, and some of it winds up in colossal garbage patches floating in remote parts of the ocean. Because of the danger that such plastics present to ocean life, some environmentalists have begun cleanup operations. Such operations typically involve sending a ship to a garbage patch, collecting as much as the ship will hold and then bringing it back to port for processing. In this new effort, the researchers suggest it would be far more efficient and greener to turn the plastic into fuel for both a processing machine and for uninterrupted operation of the ships.
The researchers note that the plastic in a garbage dump could be converted to a type of oil via hydrothermal liquefaction (HTL). In this process, the plastic is heated to 300–550 degrees Celsius at pressures 250 to 300 times that of sea-level conditions. The researchers have calculated that a ship carrying an HTL converter would be capable of producing enough oil to run the HTL converter and the ship’s engine. Under their scenario, plastic collection booms would be permanently stationed at multiple sites around a large garbage patch, able to load the plastic it collects onto ships.

When we hear the term ‘parallel universe’, we often cite the classic science fiction picture of a parallel universe; something that acts as a mirror, where on one day, in this universe, you didn’t manage to have the guts to ask that girl out, but in the parallel universe, not only did ‘you’ ask her out, but a decade later, she became your wife. We all like to subscribe to such fascinating ideas, but for a while, it was relegated to the domain of sci-fi creators/fans. The real picture tells us something a lot more interesting.
AN INFINITE NUMBER OF ‘YOUS’;

To understand why Mark Zuckerberg thinks “the metaverse” is the next frontier, consider the case of Sam Peurifoy. The 27-year-old chemistry PhD from Columbia University left his job at Goldman Sachs at the height of the pandemic and is now seeking out his fortune in crypto by playing video games.
He has recruited dozens of people from Mexico to the Philippines to a “Guild” that plays under the command of “Captain” Peurifoy. In exchange, he ponies up the funds needed to enter Axie Infinity, a game where players collect Smooth Love Potion — a digital token that can potentially be converted into real money.
Many of the malware campaigns we have detected over the last year have been global at scale, targeting anyone with little regard to their location. Recently, we discovered and began monitoring the activity behind PhoneSpy, a spyware aimed at South Korean residents with Android devices. With more than a thousand South Korean victims, the malicious group behind this invasive campaign has had access to all the data, communications, and services on their devices.
Unlike other spyware campaigns we have covered that take advantage of vulnerabilities on the device, PhoneSpy hides in plain sight, disguising itself as a regular application with purposes ranging from learning Yoga to watching TV and videos, or browsing photos. But in reality, the application is stealing data, messages, images, and remote control of Android phones. The data stolen from victim devices ranged from personal photos to corporate communications. The victims were broadcasting their private information to the malicious actors with zero indication that something was amiss.
While the victims have been limited to South Korea, PhoneSpy is an example of how malicious applications can disguise their true intent. When installed on victims’ devices, they leave personal and corporate data at risk. With mobile devices playing critical roles in distributed and remote work, it is no surprise that spyware campaigns like PhoneSpy are on the rise.
