It will also reduce travel time to Saturn’s moon Titan to just two years.

Pulsar Fusion, a UK-based space firm, is building a nuclear fusion-based rocket engine that could exceed temperatures on the Sun. The construction of the largest-ever fusion rocket engine has begun, and its exhaust speeds could exceed 500,000 miles per hour.

Nuclear fusion has long been proposed to answer our energy and climate change woes as it promises a cleaner power source. Inspired by the Sun, scientists have been working to build nuclear fusion reactors and have succeeded in generating record-high temperatures but not more energy than they have put in.

Every now and then, revolutionary technology seems to spontaneously appear out of thin air and change our world. Dynamite, penicillin, X-ray machines, and even microwaves are all examples of such revolutionary accidental discoveries.

Well, this year we may have had yet another. However, this time it is set not only to revolutionise the way we live, but potentially save our planet from looming climate change by unlocking an elusive technology: lithium-sulfur batteries.

For decades, we have been searching for the best technology to power our modern lifestyle and enable clean technology, like electric cars. Since the early ‘90s, the battery technology of choice has been lithium-ion.

Touring, a type of riding that involves long distance trips, has long been the achilles heel of electric motorcycles. While e-motos have developed to the point where they can beat combustion engine motorcycles in nearly every other metric, quick recharging required for long distance riding has yet to reach parity with a gas station fill-up. At least, that was until Lightning Motorcycle debuted what it says is the fastest charging electric motorcycle yet.

Lightning Motorcycles, the Southern California-based boutique e-motorcycle manufacturer, claims that its new fast-charging electric motorcycle can recharge nearly as fast as a combustion engine motorcycle can refuel its tank.

Previously, the quickest DC fast-charging electric motorcycles like the models from Energica or Harley-Davidson’s LiveWire One boasted a recharge time of around 30 minutes for a nearly topped-up battery.

NASA’s Juno spacecraft recently captured this spooky green flash of lightning in a massive storm swirling near Jupiter’s north pole.

The tremendous burst of lightning glows bright against the dark gray vortex of the storm, even from Juno’s vantage point 19,900 miles above the tops of Jupiter’s clouds. Lightning often flashes between the clouds of stormy Jupiter’s higher latitudes, especially in the north. NASA’s Juno spacecraft is helping shed light on the gas giant’s wild alien weather.

Citizen scientist Kevin M. Gill processed the image from Juno’s raw data.

Silicon anode batteries have the potential to revolutionize energy storage capabilities, which is key to meeting climate goals and unlocking the full potential of electric vehicles.

However, the irreversible depletion of lithium ions in silicon anodes puts a major constraint on the development of next-generation lithium-ion batteries.

Scientists at Rice University’s George R. Brown School of Engineering have developed a readily scalable method to optimize prelithiation, a process that helps mitigate lithium loss and improves battery life cycles by coating silicon anodes with stabilized lithium metal particles (SLMPs).

GENEVA: A panel of AI-enabled humanoid robots took the microphone on Friday (Jul 7) at a United Nations conference with the message: They could eventually run the world better than humans.

But the social robots said they felt humans should proceed with caution when embracing the rapidly-developing potential of artificial intelligence, and admitted that they cannot — yet — get a proper grip on human emotions.

Some of the most advanced humanoid robots were at the United Nations’ AI for Good Global Summit in Geneva, joining around 3,000 experts in the field to try to harness the power of AI and channel it into being used to solve some of the world’s most pressing problems, such as climate change, hunger and social care.

“We describe these tools as ‘giants’ when they are over 22cm long and we have two in this size range,” senior archaeologist Letty Ingrey of the UCL Institute of Archeology said in a press release.

The largest of the two hand axes, which is about 12 inches long, is “one of the longest ever found in Britain,” said Ingrey, who participated in the excavation.

Archaeologists think these types of tools were typically used to butcher or skin animals.

The 17 goals were set by the UN in 2015 and over the years, these goals have become unachievable.

The United Nations’ ‘AI for Good’ Summit is underway in Geneva and will showcase specialized robots to help the organization reach its 17 Social Development Goals (SDGs).

The goals were set in 2015, and over the years, these goals have become improbable, owing to the increasing costs of meeting the targets. The United Nations has been fighting issues like hunger, poverty, and climate change, whose prices have risen 25 PERCENT to $176 trillion from 2021 to 2022, reported Reuters.

As Meta sets its sight on introducing its virtual reality headsets to the Chinese market, Mark Zuckerberg’s contentious remarks about Beijing in the past may pose a major obstacle to his China dream. According to a recent report by the Wall Street Journal, Meta is preparing to re-enter China by selling the Oculus Quest VR headset in China. If Tesla can sell cars and Apple can sell phones in China, why isn’t Meta present there? Zuckerberg asked in a recent internal meeting.

But some observers are quick to point out that Zuckerberg has a history of criticizing the Chinese government, a stance that will likely be amplified in the current climate of heightened tensions between the U.S. and China.… More.
