Lithium metal batteries could store much more charge in a given space than today’s lithium-ion batteries, and the race is on to develop them for next-gen electric vehicles, electronics and other uses.

But one of the hurdles that stand in the way is a silent battle between two of the battery’s parts. The liquid between the battery electrodes, known as the electrolyte, corrodes the surface of the lithium metal anode, coating it in a thin layer of gunk called the solid-electrolyte interphase, or SEI.

Although formation of SEI is believed to be inevitable, researchers hope to stabilize and control the growth of this layer in a way that maximizes the battery’s performance. But until now they have never had a clear picture of what the SEI looks like when it’s saturated with electrolyte, as it would be in a working battery.

Three pilot tests for digital transactions without the internet were successfully completed by India’s central bank (RBI). Based on the experience of 240,000 transactions, the RBI has created a framework which will be available on the platforms of banks, credit cards, and payment apps.

Aluminium Air batteries have been a thing for a while — but now a UK inventor says he’s solved one of the biggest problems with them — the toxicity of the electrolyte they’ve traditionally used.

Does this make Aluminium Air batteries viable?

For a few brief moments, the high-powered lasers generated 1.3 megajoules of fusion energy.


A breakthrough experiment last month at Lawrence Livermore National Laboratory’s (LLNL) National Ignition Facility (NIF) in California has turned up a whopping 1.3 megajoules of energy, or about three percent of the energy contained in one kilogram of crude oil. The work, as outlined in the journal Physical Review E, puts physicists “at the threshold of fusion ignition,” according to the lab’s press release.

Nuclear fusion, in the simplest terms, is a reaction in which atoms are smashed together to generate an abundance of energy. In some ways, it’s less dangerous than nuclear fission —a process that involves splitting heavy, unstable atoms into two lighter ones—and has the potential to create a lot more energy.

All of today’s functional nuclear power plants currently use nuclear fission, and scientists have long been on the hunt for a way to make nuclear fusion a reality; consider it a kind of holy grail of clean energy.

Space based weaponry.


In a bit to deepen defence cooperation, the United States and Japan have agreed to collaborate on several new ventures. This includes developing hypersonic and space-based weaponry and a new deal on sharing the cost of US troops in Japan.

Remember how China’s Tianwen-1 spacecraft released a remote camera to take a picture of itself during its flight to Mars, back in late 2020? Now in Mars orbit, Tianwen-1 has done it again, releasing another mini remote camera. Except this time, the planet Mars is part of the view.

The images are stunning.

The China National Space Administration (CNSA) published three pictures, including a shot of the spacecraft in orbit with Mars in the background, a picture of Mars’ northern ice caps, and the first full photo of the orbiter.

An autonomous drone delivers a defibrillator – and saves the life of a cardiac arrest patient. Swedish drone company Everdrone says it’s a medical history first – but the grateful patient says that it’s a technology that should be used everywhere.

For heart attack patients, seconds count: the minutes that an ambulance can take to reach a patient in cardiac arrest can mean the difference between life and death. Autonomous drones offer a game-changing solution. Autonomous drone specialists Everdrone operate the drone delivery system in Region Västra Götaland, supported by Vinnova, Swelife and Medtech4Health. Their innovative solution has been developed with Center for Resuscitation Science at Karolinska Institutet, SOS Alarm and Region Västra Götaland.

Now, the technology can claim a life saved. In Trollhättan, Sweden on December 92,021, an Everdrone autonomous drone delivered a defibrillator that helped save the life of a 71-year-old man.
