A newly described species of wild tobacco that scientists found growing next to a highway truck stop in Western Australia is covered in sticky glands that trap and kill small insects, including gnats, aphids and flies.
While a range of carnivorous plants are known across the plant kingdom, this is the first wild tobacco plant discovered to kill insects. Dubbed Nicotiana insecticida, it was uncovered by a project looking for tobacco plants across Australia.
The team, which included Mark Chase of London’s Royal Botanic Gardens, Kew, collected seeds from the insecticidal plant at a truck stop on the Northwest Coastal Highway, and then cultivated them at Kew, where the plants went on to develop the same sticky glandular hairs and to kill insects inside the greenhouses.
Public transportation just got way cooler. Premium Swedish electric boat maker Candela has just unveiled the new Candela P-12, an electric hydrofoil water taxi.
Designed to replace traditional diesel-powered ferries, the Candela P-12 uses an electric powertrain combined with a carbon fiber hull and hydrofoils to create a super-efficient drive system.
The 8.5 meter (28 foot) water taxi can fit up to 12 passengers in its panoramic-view cabin.
This axion insulating state was realized, Bansil says, by combining certain metals and observing their magnetoelectric response. In this case, researchers used a solid state chip composed of manganese bismuth telluride, which were adhered together in two-dimensional layers, to measure the resulting electric and magnetic properties.
Researchers note that such a finding has implications for a range of technologies, including sensors, switches, computers, and memory storage devices, among many others. The “storage, transportation, and manipulation of magnetic data could become much faster, more robust, and energy-efficient” if scientists can integrate these new topological materials into future devices, the researchers write.
“It’s like discovering a new element,” Bansil says. “And we know there’s going to be all sorts of interesting applications for this.”
CHINA’S NEW 600 KM PER HOUR LEVITATED TRAIN is the next step in its system of 38,000 km of high speed rail lines covering the nation. China’s land area is almost exactly the same as the USA’s, but, by contrast, the USA has ZERO km of high speed rail. China is financing this and other massive infrastructural networks in the same way that the US formerly financed all its major infrastructure— with governmental financing. Every highway, every railway system, every waterway, etc., etc., in the USA was built in the same way, but we stopped building such systems.
It’s fast, very fast.
In fact, it is the fastest train the world.
Capable of speeds up to 600 km/h ((373 mph), China’s high-speed Maglev electric bullet train could very well close the gap between rail-based trains with a maximum speed of 350 km/h and aircraft with a flight speed of 800 to 900 km/h.
Mateo Jaramillo sees the future of renewable energy in thousands of iron pellets rusting away in a laboratory in Somerville, Massachusetts.
Jaramillo is chief executive of Form Energy, a company that recently announced what it says is a breakthrough in a global race: how to store renewable energy for long periods of time.
The aircraft, evocatively called Skydweller and built by a U.S.-Spanish aerospace firm Skydweller Aero, could help the Navy keep a watchful eye on the surrounding seas while escorting ships months at a time or act as a communications relay platform. The company was awarded a $5 million contract by the U.S. Navy to develop the aircraft.
To stay airborne for so long, the pilotless craft would have 2900sq ft of solar cells on its wings.
Skydweller Aero’s latest flight test of a modified solar-powered aircraft will provide the real-world data necessary for the U.S.-Spanish startup’s engineers to start developing and testing their proprietary autonomous flight software.
Established in 2019 following the acquisition of Swiss nonprofit Solar Impulse’s Solar Impulse 2 aircraft—which circumnavigated the globe in 2016 — Skydweller is headquartered in Oklahoma, with offices in the Washington D.C. region and a flight test facility in Albacete, Spain, roughly two hours south of their engineering operations in Madrid. During the two-and-a-half-hour optionally-piloted flight demonstration in Albacete, Skydweller’s engineering team completed initial validation of their new flight hardware and autopilot’s ability to initiate and manage the aircraft control, actuation, and sensor technology systems.
A pilot was in the cockpit of the Solar Impulse 2, working in tandem with another operator who controlled the movements of the aircraft remotely from the ground.
This next jump in battery-tech could solve a lot of EV problems.
The world of the internal combustion engine will sadly, but very necessarily, come to a close at some point in many of our lifetimes. Hybrids and electric vehicles are becoming more affordable and more advanced at a rapid pace, which means batteries are taking the place of fossil fuels. This has led to an equally rapid progression in battery technology, with the main goals of improving capacity, charging times, and safety. One major advancement in this field is the advent of solid-state batteries, which promise to push the boundaries of the limitations that current lithium-ion batteries carry.
Electric vehicles have been powered by lithium-ion batteries for years, which are similar to the ones used in laptops, cell phones, and other consumer electronics. They are constructed with a liquid electrolyte inside, which makes them heavy and susceptible to instability at high temperatures. Because each individual battery pack can’t generate all that much energy on its own, several have to be linked together in series, further adding to the weight. The cost of engineering, manufacturing, and installing battery packs makes up a considerable portion of the overall cost of an electric vehicle.
Just like a cell phone, the lithium-ion batteries in electric vehicles need to be recharged. The speed at which an electric vehicle’s batteries can be charged depends on the vehicle itself, the type of batteries it uses, and on the charging infrastructure. In general, public charging stations fall into either the Level 2 or Level 3 categories, both of which can charge an EV far quicker than a standard household outlet. Level 1 and Level 2 chargers provide power to the on-board charger via AC power, which is converted to DC power to charge the battery. Level 3, which can also be called DC Fast Charging, bypasses that on-board generator and instead charges the battery directly and at a much quicker rate. Over time, however, both the battery capacity and the ability to reach peak charging rates degrade.
