Nowadays, over half of the seafood we enjoy is farm-raised rather than caught in the open. A technique recently developed by Japanese scientists has the potential to fundamentally change yields for farmed fish. And the secret is in the lighting…
Flying taxis, more technically known as electric vertical take-off and landing (eVTOL) vehicles, might actually — finally — become a feasible technology thanks to a new development in battery technology.
Ironically, the hardest part of designing and building eVTOLs isn’t the vehicle itself. Instead, it’s solving the challenging energy situation that eVTOLs face: Any battery that’s powerful enough to lift the thing is almost certainly too heavy and slow-charging to make a trip worthwhile. But a team of Pennsylvania State University engineers tested new batteries that can both recharge in a matter of minutes and survive thousands of charge cycles, according to research published Monday in the journal Joule, making eVTOLs seem a whole lot more realistic.
The energy-dense lithium-ion batteries represent a major leap forward in electric vehicle energy tech, according to The Independent. Both could be charged for a 50-mile journal in under ten minutes, making eVTOLs far more economically viable because each vehicle could take more trips per day.
With the rise of the lithium-based battery, demand for this soft, silvery-white metal – the lightest solid element in the periodic table – has exploded. With the race to zero carbon by 2050 gathering steam, forcing the electrification of transport, lithium will be an even more valuable asset in the next 30 years.
The supply of raw materials for batteries could even end up being a national security issue, too; China’s global leadership on high-volume EV production has put it ahead of the game, and while the majority of ground-based lithium reserves are in the “lithium triangle” of Chile, Bolivia and Argentina, China controls more than half’s the world’s supply simply through investments and ownership. It has shown in the past that it’s not afraid to wield commodity supplies as a weapon.
But as with other metals like uranium, land-based lithium reserves pale in comparison to what’s out there in the sea. According to researchers at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST), there’s about 5000 times as much lithium in the oceans as there is in land deposits, and a newly developed technology could start extracting it cheaply enough to make the big time – while producing hydrogen gas, chorine gas and desalinated water as a bonus.
In our series, Real Food, we take a look at the growing trend of vertical farming. Companies like Aerofarms are rethinking how we grow vegetables by going up to provided fresh and affordable produce. Michelle Miller reports.

But the above-ground structure of the Baekdu-daegan Seed Vault belies the true size of this sprawling underground structure.
The idea of building a Seed Vault in South Korea initially began with the Nagoya Protocol on Access and Benefit Sharing in 2010. Officially launched in 2016 and designated a national security facility since 2019, the Baekdu-daegan Seed Vault’s main purpose is to secure biodiversity from threats such as natural disasters, climate change and war, to support sustainable life for human beings.
The Baekdu-daegan Seed Vault in Korea is one of only two built worldwide — the other is Svalbard Global Seed Vault, which opened in 2008 on an arctic Norwegian Island. It currently stores over 90000 types of seeds.
China has announced a milestone in the development of clean, sustainable energy by setting a new world record for the longest duration of temperatures needed for fusion to occur.
The Experimental Advanced Superconducting Tokamak (EAST) located in Hefei, Anhui Province, is the successor to HT-7, China’s first superconducting tokamak, which retired in 2013. The Hefei Institutes of Physical Science (HIPS) is conducting the experiment for the Chinese Academy of Sciences (CAS).
Professor Gong Xianzu, a researcher at the CAS Institute of Plasma Physics (IPP) who is leading the project, announced the breakthrough. The reactor achieved not one but two milestones. Firstly it reached a plasma temperature of 120 million degrees Celsius for 101 seconds. This is 20% hotter and five times longer than last year, when EAST managed 100 million degrees Celsius for 20 seconds. Secondly, it reached an even higher peak temperature of 160 million degrees Celsius, lasting for 20 seconds.
The applications are for trademarks for the company’s ‘T’ logo design “and two other iterations of ‘Tesla’ stylised logo for use in the food industry”, the report said.
Moneycontrol could not independently verify the report.
As per the report, the three applications are for “restaurant services, pop-up restaurant services, self-service restaurant services, take-out restaurant services” and are filed under a trademark law provision indicating that Tesla intends to use, but has not done so yet.
Family sedan breaks speed record.
The new Tesla Model S Plaid has reportedly achieved a new quarter-mile world record with a 9.2-second run, according to Jay Leno, who was at the racetrack for the record attempt.
After several months of delays, Tesla is apparently finally going to start deliveries of the new and updated Model S next week, including the new top performance Plaid version.
The automaker announced some impressive specs with 390 miles of range, 200 mph top speed, and 1.99 second 0–60 mph acceleration.
Robots and artificial intelligence will replace workers on Australia’s first fully automated farm created at a cost of $20 million.
