Carcopter is a flying hydrogen-powered formula 1 car conceived
Posted by Quinn Sena in categories: futurism, transportation
is it a car? is it a helicopter? no, it’s carcopter. conceived by french start-up, MACA, this hydrogen-powered concept aims to revolutionize the way we travel. with its aerodynamic body and theoretical top speed of 153 mph (246 kph), this prototype in question is designed for a racing scenario. it intends to be the first (manned) flying hydrogen formula 1 car. the highly-futuristic vehicle is set to be shown at annual tech event, CES 2021.

Fiat Chrysler plans to mass produce flying cars by 2023
Posted by Quinn Sena in categories: sustainability, transportation
One of electric aviation’s greatest challenges (beyond safety certification) is mass production. Designing a working prototype is now table stakes in this industry. As Tesla found out, heavy manufacturing at scale can easily bankrupt even the most well-funded companies.
To solve this problem, Archer turned to Fiat Chrysler Automobiles (FCA), which produces about 4 million cars per year at its 100 manufacturing facilities and 40 R&D centers. FCA described it as a mutually beneficial arrangement: It gains experience electrifying vehicles (where it lags behind), and Archer gains access to low-cost manufacturing expertise. FCA already helped design the aircraft’s cockpit and will allow the production of “thousands of aircraft” per year, according to a company spokesperson. The first aircraft is scheduled to be revealed in early 2021 with the first public flights in 2024.
Delays are likely given the complexity of launching, literally, a new vehicle. But the announcement fulfills the initial prediction made last year by John Hansman, director of MIT’s International Center for Air Transportation: “You’ve seen some shakeup in electric aviation, but also see it get closer to reality” in 2020, he said. “It’s clear there will be the emergence of a new class of electric airplanes. In 2021, you’ll see hybrid and battery aircraft in service or close to being in service.”

Newly discovered fungi turn flies into zombies and devour them from the inside out
Posted by Magaly Santiago in category: food
This type of fungi isn’t in the depths of the rainforest but in Denmark.
Nature scares sometimes.
Two newly discovered fungi eat flies from the inside out while dropping new spores out of holes dissolved in the living flies’ abdomens.

Roadmap To End Aging — Understand The Hallmarks To Change Your Direction
Posted by Mark Parkins in categories: food, life extension, neuroscience
It can be done. And it can be done sooner than many realise…even within YOUR lifetime. Imagine… Reaching triple digits with the health, fitness and body of an athletic 30 year old… It is entirely within reach now, it may be even less than a decade away. All we need to do is repair the damage that living and our metabolism create, it is slowly accumulating, which is why it takes 7 or 8 decades to rear its ugly head in most people, so one treatment should keep things under control for many years, and by then science will have advanced immeasurably, improving the treatments to whole new levels… Then you can dream of reaching 4 digits…then 5…then 6… BUT You need to stay in good enough shape to last long enough to see the treatments perfected and available. So watch your diet, your mental and physical health, your weight, and look to use occasional fasting, and time restricted eating, along with saunas and cold showers (or any hot/cold therapy), etc., to keep yourself at your optimum until that days arrives. If you want to know more, then this video breaks it down into even more detail. Have a great day and enjoy your journey into the future…

The compound that makes chili peppers spicy also boosts perovskite solar cell performance
Posted by Saúl Morales Rodriguéz in categories: chemistry, solar power, sustainability
Scientists in China and Sweden have determined that a pinch of capsaicin, the chemical compound that gives chili peppers their spicy sting, may be a secret ingredient for more stable and efficient perovskite solar cells. The research, published January 13 in the journal Joule, determined that sprinkling capsaicin into the precursor of methylammonium lead triiodide (MAPbI3) perovskite during the manufacturing process led to a greater abundance of electrons (instead of empty placeholders) to conduct current at the semiconductor’s surface. The addition resulted in polycrystalline MAPbI3 solar cells with the most efficient charge transport to date.
“In the future, green and sustainable forest-based biomaterial additive technology will be a clear trend in non-toxic lead-free perovskite materials,” says Qinye Bao, a senior author of the study from East China Normal University. “We hope this will eventually yield a fully green perovskite solar cell for a clean energy source.”
While metal halide perovskite semiconductors represent a promising component for state-of-the-art solar cell technologies, they are plagued by nonradiative recombination, an undesirable electron-level process that reduces efficiency and exacerbates heat losses. Bao and colleagues sought out a natural, forest-based, inexpensive additive to overcome this limitation and enhance solar cell performance.

Can sodium-ion batteries replace trusty lithium-ion ones?
Posted by Saúl Morales Rodriguéz in category: futurism
Sodium-ion batteries are a potential replacement for lithium batteries, but the anodes—positively charged electrodes—that work well for lithium-ion batteries don’t provide the same level of performance for sodium-ion batteries.
Amorphous carbon, which lacks a crystalline structure, is known to be a useful anode, because it has defects and voids that can be used to store sodium ions. Nitrogen/phosphorus-doped carbon also offers appealing electrical properties.
In Applied Physics Reviews, researchers in China from Zhejiang University, Ningbo University, and Dongguan University of Technology describe how they applied basic physical concepts of atomic scale to build high-performance anodes for sodium-ion batteries.

A framework to assess the importance of variables for different predictive models
Posted by Saúl Morales Rodriguéz in categories: information science, robotics/AI
Two researchers at Duke University have recently devised a useful approach to examine how essential certain variables are for increasing the reliability/accuracy of predictive models. Their paper, published in Nature Machine Intelligence, could ultimately aid the development of more reliable and better performing machine-learning algorithms for a variety of applications.
“Most people pick a predictive machine-learning technique and examine which variables are important or relevant to its predictions afterwards,” Jiayun Dong, one of the researchers who carried out the study, told TechXplore. “What if there were two models that had similar performance but used wildly different variables? If that was the case, an analyst could make a mistake and think that one variable is important, when in fact, there is a different, equally good model for which a totally different set of variables is important.”
Dong and his colleague Cynthia Rudin introduced a method that researchers can use to examine the importance of variables for a variety of almost-optimal predictive models. This approach, which they refer to as “variable importance clouds,” could be used to gain a better understanding of machine-learning models before selecting the most promising to complete a given task.
