Scientists have used mushrooms to make biodegradable computer chips
Year 2022 đđ
Foraging for fungi may not only mean mushrooms are on the menu. New research has shown that mushroom skins could provide a biodegradable alternative to some plastics used in batteries and computer chips, making them easier to recycle.
Researchers from the Johannes Kepler University in Austria were working on flexible and stretchable electronics, with a focus on sustainable materials to replace non-degradable materials, when they made their discovery, published in the journal Science Advances Friday.
AI comes to the farm: New technology tackles acres of weeds quickly by using robotics and lasers
Weeds are one of the most âtedious, time-consuming and challengingâ elements of farming, Carbon Robotics told Fox Business via email.
The LaserWeeder can eliminate over 200,000 weeds per hour and offer up to 80% cost savings in weed control.
Carbon Robotics CEO and founder Paul Mikesell âknows farmers and has a lot of friends who are farmers,â he said.
This tiny glass pyramid could make solar panels cheaper than ever
Photovoltaic cells work best when sunlight is incident directly on them. To make the most of sunlight available during the day, scientists have relied on solar tracking to move panels in sync with the Sun as its travels across the sky. However, installing these systems increases the cost of deploying solar panels, which is a significant obstacle to their wide-scale adoption.
Flipper hacking device on track to make $80M worth of sales
You may have stumbled across the Flipper Zero hacking device thatâs been doing the rounds. The company, which started in Russia in 2020, left the country at the start of the war and moved on since then. It claims it no longer has ties to Russia and that it is on track to sell $80 million worth of its products this year after selling almost $5 million worth as Kickstarter preorders â and it claims it sold $25 million worth of the devices last year.
So what are they selling? Flipper Zero is a âportable gamified multi-toolâ aimed at everyone with an interest in cybersecurity, whether as a penetration tester, curious nerd or student â or with more nefarious purposes. The tool includes a bunch of ways to manipulate the world around you, including wireless devices (think garage openers), RFID card systems, remote keyless systems, key fobs, entry to barriers, etc. Basically, you can program it to emulate a bunch of different lock systems.
The system really works, too â Iâm not much of a hacker, but Iâve been able to open garages, activate elevators and open other locking systems that should be way beyond my hacking skill level. On the one hand, itâs an interesting toy to experiment with, which highlights how insecure much of the world around us actually is. On the other hand, Iâm curious if itâs a great idea to have 300,000+ hacking devices out in the wild that make it easy to capture car key signals and gate openers and then use them to open said apertures (including Tesla charge ports, for some bizarre reason).
Inside the startup creating the future of food production
In a 1931 essay, Winston Churchill wrote about how he sees the future of food production: âWe shall escape the absurdity of growing a whole chicken in order to eat the breast or wing, by growing these parts separately under a suitable medium,â he wrote.
Fast forward some 90 years, and Churchillâs prediction is coming true, thanks in part to Israeli food-tech company Aleph Farms, which has developed a unique method to cultivate steak meat from isolated cow cells.
First to develop cultured steak.
This salty gel could harvest water from desert air
MIT engineers have synthesized a superabsorbent material that can soak up a record amount of moisture from the air, even in desert-like conditions.
As the material absorbs water vapor, it can swell to make room for more moisture. Even in very dry conditions, with 30 percent relative humidity, the material can pull vapor from the air and hold in the moisture without leaking. The water could then be heated and condensed, then collected as ultrapure water.
The transparent, rubbery material is made from hydrogel, a naturally absorbent material that is also used in disposable diapers. The team enhanced the hydrogelâs absorbency by infusing it with lithium chloride â a type of salt that is known to be a powerful dessicant.
Passive cooling system could benefit off-grid locations
As the world gets warmer, the use of power-hungry air conditioning systems is projected to increase significantly, putting a strain on existing power grids and bypassing many locations with little or no reliable electric power. Now, an innovative system developed at MIT offers a way to use passive cooling to preserve food crops and supplement conventional air conditioners in buildings, with no need for power and only a small need for water.
The system, which combines radiative cooling, evaporative cooling, and thermal insulation in a slim package that could resemble existing solar panels, can provide up to about 19 degrees Fahrenheit (9.3 degrees Celsius) of cooling from the ambient temperature, enough to permit safe food storage for about 40 percent longer under very humid conditions. It could triple the safe storage time under dryer conditions.
The findings are reported today in the journal Cell Reports Physical Science, in a paper by MIT postdoc Zhengmao Lu, Arny Leroy PhD â21, professors Jeffrey Grossman and Evelyn Wang, and two others. While more research is needed in order to bring down the cost of one key component of the system, the researchers say that eventually such a system could play a significant role in meeting the cooling needs of many parts of the world where a lack of electricity or water limits the use of conventional cooling systems.
Porsche is developing an exclusive electric sports boat
With ambitious goals of being a leader in sustainable mobility, Porsche has joined forces with Frauscher Shipyard in Austria to engineer an electric yacht that is also intended to set standards on the water with its typical Porsche E-Performance. The vehicle is called the Frauscher x Porsche 850 Fantom Air highlighting the collaboration that made it possible.
