New types of cathodes, suitable for advanced energy storage, can be developed using beyond-lithium ion batteries.

The rapid development of renewable energy resources has triggered tremendous demands in large-scale, cost-efficient and high-energy-density stationary energy storage systems.

Lithium ion batteries (LIBs) have many advantages but there are much more abundant metallic elements available such as sodium, potassium, zinc and aluminum.

The United Arab Emirates’ first interplanetary mission successfully took off from the southern tip of Japan on July 20th, sending up a car-sized probe bound for the planet Mars. The spacecraft, called Hope, will now spend the next seven months traveling through deep space, before inserting itself into Mars’ orbit in February.

Study shows the vaccine is safe, but it is still too soon to know if it can stop people from being infected.

Balloon-based internet is currently flying high in Kenya, a win the Alphabet subsidiary. Here’s what they’re planning next.

Circa 2018

Back in July 2018, researchers at Purdue University created the world’s fastest-spinning object, which whipped around at 60 billion rpm – and now that seems like the teacup ride at Disneyland. The same team has now broken its own record using the same technique, creating a new nano-scale rotor that spins five times faster.

Like the earlier version, the whirling object in question is a dumbbell-shaped silica nanoparticle suspended in a vacuum. When it’s set spinning, this new model hit the blistering speed of over 300 billion rpm. For comparison, dentist drills are known to get up to about 500,000 rpm, while the fastest pulsar – which is the speediest-spinning known natural object – turns at a leisurely 43,000 rpm.

Amazing.

Brain-computer interface could also give people ‘enhanced abilities’.

“Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid’s potential to make threatening close approaches to the Earth. Specifically, all asteroids with a minimum orbit intersection distance (MOID) of 0.05 au or less are considered PHAs,” NASA said in a statement.

According to NASA, asteroid 2020 ND is about 170 metre-long will be as close as 0.034 astronomical units (5,086,328 kilometres) to our planet. The asteroid is travelling at a great speed of 48,000 kilometres per hour. The distance from the earth is what categories this asteroid as “potentially dangerous”.

2016 DY30 is headed in the direction of Earth at a speed of 54,000 kilometres per hour whereas 2020 ME3 is travelling at 16,000 kilometers per hour. The 2016 DY30 is the smaller asteroid of the two as it is 15 feet wide.

Early results in The Lancet on Oxford coronavirus vaccine clinical made by AstraZeneca suggest the COVID-19 vaccine is safe and induces antibodies and T cell response.

“D-Theory of Time, or Digital Presentism, gives us a coherent picture of temporal ontology: In the absence of observers, the arrow of time doesn’t exist — there’s no cosmic flow of time. With that in mind, your timeless cosmic self resides as a hyperdimensional being outside the ordinary space-time dimensionality of your experiential self… In fact, if we are to create high fidelity first-person simulated realities that also may be part of intersubjectivity-based, multiplayer virtualities, D-Theory of Time gives us a clear-cut guiding principle for doing just that.” –Alex M. Vikoulov, The Physics of Time: D-Theory of Time & Temporal Mechanics.
