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?

JFrog’s senior director of security research said the vulnerability has a root cause similar to Log4Shell.
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.

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.
Movano has unveiled its new smart ring, which can track steps, sleep, heart rate, heart rate variability, and several other important health metrics.
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.
From the fMRI scans, the researchers saw the same areas of the brain light up but with different activation patterns, depending on whether the dogs were hearing the story in their native language or a new one—suggesting that they were neurologically processing differences between the two languages.
Then the researchers tried to test whether the dogs were responding to specific characteristics intrinsic to each language. Were the animals reacting to actual changes in speech patterns—that Hungarian words put stress on the first syllable, for instance—or just responding to basic differences in fundamental auditory signatures between the two languages—alterations in tones that occur during vowel pronunciation? They tested this by playing recordings in which the speech from the story had been garbled, resulting in gibberish that “sounded” like Hungarian or Spanish. Again, the team saw different patterns in brain activity when a dog heard real human speech instead of speechlike gibberish, although the researchers cannot yet say whether this is evidence that dogs can recognize human speech as speech (sounds strung together in a meaningful way for humans to communicate with one another)—or whether their brain was just responding to the more natural sound when compared with the weird-sounding gibberish. There was no change in brain activity between hearing Spanish gibberish versus Hungarian gibberish, however, implying that the canines’ brain was not just responding to the different tonal qualities.”
A new study’s authors say their investigation represents the first time that a nonhuman brain has been shown to detect language.
