Japan aims to beam solar power from space by 2025
Japan is aiming to become the first country in the world to beam solar energy from space back to Earth to generate electricity at scale. A public-private partnership led by Japanese space agency JAXA will see the first satellite transmitters set up by 2025, according to local reports, The satellites will convert solar power into microwaves and send them to ground-based receiving stations, which then convert it into electrical energy. “If we can demonstrate our technology ahead of the rest of the world, it will also be a bargaining tool for space development with other countries,” Kyoto University professor Naoki Shinohara told Nikkei. The concept, which was first theorised in 1968, has several advantages over terrestrial solar power setups, notably being able to harvest solar energy for much longer, unhindered by the Sun’s typical cycle. Microwaves are capable of passing through clouds, so the technology is also able to operate in adverse weather conditions. Japan has already achieved several firsts in this field, having been the first to transmit power via microwaves in space in the 1980s. In 2015, JAXA scientists followed this up with another breakthrough that saw 1.8 kilowatts of power beamed down to an Earth-based receiver – roughly enough to power an electrical kettle. Several other countries and regions are also working on the technology, with the European Space Agency unveiling a plan last year to test the viability of space-based solar power. The Solaris program aims to make Europe a global leader in this untapped energy resource, with the hope of setting up a development program in 2025. More research still needs to be done before it becomes feasible at a significant scale, though recent advances in high-efficiency solar cells, wireless power transmission and robotic in-orbit assembly mean that China and the US are also working on ways to tap the Sun’s energy from space. Among the concerns surrounding the technology are the health impacts of low-power microwaves on humans, animals and plants. “These are the kind of technical questions that Solaris will look into, to explore further the feasibility of the concept,” Sanjay Vijendran, ESA’s lead for the Solaris proposal, said last year. “As an added plus, any breakthroughs achieved in these areas will be valuable in their own right, applicable to many other spaceflight endeavours.” Read More Scientists break world record for solar power window material Huge ‘plume’ seen coming out of nearby moon that could support alien life Elon Musk meets Chinese foreign minister on first visit for three years Mitigating ‘extinction’ from AI should be ‘global priority’, experts say

Makeup By Mario’s Lip Plumping Serum Doesn’t Fake Filler — & It’s Not Trying To
As a fan of pretty much everything Mario Dedivanovic does, my expectations are high when a new product bearing his name comes out. I’ve yet to be disappointed. Among my vast collection of makeup, I count his long-lasting lip liners, pigmented matte shadows, inky eyeliners, and more among my daily favorites. Naturally, I was excited to try his signature lip treatment, the MoistureGlow Plumping Lip Serum.

Putin jails Russian soldiers for refusing to return to Ukraine
Two Russian soldiers have been jailed for refusing to return to the frontline in Ukraine, the UK Ministry of Defence (MoD) said. In an intelligence update posted on Twitter, the ministry said two Russian soldiers were sentenced to serve at least two years in a penal colony by a military court for refusing to obey orders to return to the front in Ukraine. It comes after Russian independent media outlet Mediazona reported that Russia was convicting close to 100 soldiers a week for refusing to fight. The defence ministry predicted “there will be approximately 5,200 convictions a year for refusing to fight” if the trend continues. The high rate of convictions demonstrates the “poor state of morale” and “reluctance” to fight in the Russian Army, the MoD said. The update continued: “Refusal to fight likely reflects the lack of training, motivation and high stress situations Russian forces face along the entire Ukrainian frontline.” However, the defence ministry said it is likely Russia mitigates losses in soldiers by “committing a mass of poorly trained soldiers to the frontline.” “Since Russia’s September 2022 partial mobilisation, Russia has adapted its approach to warfare by utilising sheer mass for offensive and defensive operations,” the update explained. In September 2022, Russian president Vladimir Putin announced a partial mobilisation of 300,000 military reservists for the war in Ukraine. The call-up prompted hundreds of thousands of men to flee the country. Outbound flights were full and neighbouring countries received large influxes. Soon afterwards, Mr Putin toughened up penalties for desertion and refusal to fight, making the offences punishable by up to 10 years in prison, or 15 years for voluntary surrender to enemy forces. But first-time offenders may be exempted from criminal liability “if he took measures for his release, returned to his unit or place of service and did not commit other crimes while in captivity”, according to the new law. Within weeks of the boost to Russian numbers, UK defence chiefs concluded many of the newly mobilised soldiers were poorly equipped, possibly with weapons in a “barely usable” condition. Earlier this year, the MoD suggested Russian troops were using shovels for hand-to-hand combat in Ukraine because of an ammunition shortage. In the latest development in Putins’s war in Ukraine, at least four of Russia’s military transport planes were damaged after Ukraine launched its biggest drone attack on Russian soil since the beginning of the invasion. The Il-76 transport aircraft were damaged after drones hit an airport in the western Pskov region, located 660km north of the Ukrainian frontier and near the borders of Estonia and Latvia.

Erling Haaland says Premier League goal record ‘something you can’t think of’
Erling Haaland has not ruled out breaking Alan Shearer’s all-time Premier League goalscoring record. Shearer scored 260 Premier League goals in 441 appearances during 14 seasons as a player with Blackburn and Newcastle before retiring in 2006. Norway and Manchester City striker Haaland has scored 44 Premier League goals in 42 appearances since arriving in England from Borussia Dortmund in time for the start of the 2022-23 season. The 23-year-old, who has notched eight goals in seven top-flight games this season, jokingly told the Telegraph: “How long is my contract? Three years and 10 months (left)? So, there is still time to do it, no?” When asked if he was serious about breaking the record during that time, Haaland added: “I didn’t say that! “That’s something you can’t think of. You have to think of the next game, the season and then these things come after a while. But if I will still be 15 years longer in England then why not? We will see.” Haaland, who has scored a total of 199 goals in 203 career appearances for Salzburg, Dortmund, City and Norway, said it was now a bigger story whenever he does not hit the target. Norwegian media when I don’t score: Goalless! That’s the headline. That’s how it is. It’s a good thing. I am not complaining at all but, also, I signed for City to score goals Erling Haaland He said: “Norwegian media when I don’t score: Goalless! That’s the headline. That’s how it is. It’s a good thing. I am not complaining at all but, also, I signed for City to score goals. “So, it was also a bit expected – maybe not so many – but I am still the one who is going to get the ball in the back of the net.” Haaland can often appear to drift out of games without touching the ball for long periods and explained how he slips into a ‘zombie’ state as he waits for his chance. “I go out of my body and become a zombie,” he added. “It’s kind of a bit of a ‘zone out’. Like looking around. Waiting for the chance. And when the chance comes I know I have to be ready, you know?” Read More Mikel Arteta urges Arsenal to bring City losing streak to an end On this day in 2010: Rebecca Adlington wins Commonwealth Games 800m gold Tottenham boss Ange Postecoglou would eradicate VAR in its current form
