Paris Hilton has surprised the world with the announcement of her second child. The American socialite, 42, took to Instagram on Thanksgiving (23 November) to share the arrival of her second baby with husband Carter Reum - a baby girl. She revealed the news by posting a photo of a pink pajama set with the name “London” inscribed on the Peter Pan collared top. “Thankful for my baby girl,” the DJ captioned the post. She placed a pair of hot pink heart-shaped sunglasses and a brown, knitted toy bunny alongside the cosy PJ’s. Fellow celebrities and fans rushed to congratulate the mother of two on the arrival of her daughter. Supermodel Naomi Campbell commented under the Instagram post: “Congratulations @parishilton & welcome Londom [sic].” “Omggg! Congratulations you guys! This is so amazing!” commented fashion designer Kimora Lee Simmons. “Can’t wait to meet London!” Singer Demi Lovato wrote: “Omg congratulations!!!” Meanwhile, Hilton’s aunt and Real Housewives of Beverly Hills star, Kyle Richards, left a series of pink heart emojis in the comments section. In addition to baby London, Hilton and Reum are already parents to their 10-month-old son, Phoenix Barron. The couple - who were married in November 2021 - welcomed their first child via surrogate in January. The heiress also celebrated the birth of her second child on TikTok, where she shared videos of her family’s sweet reaction to the new arrival. In one TikTok video posted on Thanksgiving, Hilton can be heard asking her niece and nephew: “You guys excited for your new cousin?” In response, her nephew asked: “You have two babies?” “I have two babies,” she replied. @parishilton Priceless moments? Family is everything? ♬ original sound - ParisHilton In another TikTok video, Hilton and Reum can be seen celebrating Phoenix becoming a big brother. “Big brother! Big brother!” the couple chanted as Hilton held up Phoenix, who was wearing a grey onesie and white knitted turkey-themed beanie. “OMG ANOTHER BABY!!!! A GIRL SO HAPPY FOR YOU!!!!” one fan commented on TikTok, to which Hilton wrote back: “My princess has arrived!!” The surprise birth of Hilton’s daughter may not come as a surprise at all, considering the influencer waited until her son Phoenix was born to announce his arrival on Instagram. “You are already loved beyond words,” she captioned the post on 24 January, which showed her holding her son’s tiny hand. Just one month after welcoming her newborn son, the DJ revealed that her family didn’t know their surrogate gave birth until Phoenix was one week old. “Not even my mom, my sisters, my best friend knew until he was over a week old,” Hilton explained on her iHeartRadio podcast, This Is Paris. “It was really nice to have that with Carter, be our own journey together. I just feel like my life has been so public, and I’ve never really had anything be just mine.” Read More Paris Hilton’s husband reveals why she wanted to keep their son’s birth secret Paris Hilton makes grand entrance into F1 party but ‘no one’ is there to watch Jennifer Aniston revealed her wellness secret on Instagram.

Scientists have discovered how to double the efficiency of an ultra-lightweight solar cell, which they claim could be used to harvest the Sun’s energy in space at a never-before-seen scale. The next-generation solar panels, built by a team from the University of Pennsylvania, use layers that are over a thousand times thinner than a human hair, yet capable of absorbing a comparable amount of sunlight to commercially available solar cells. The extreme thinness earned them the label two-dimensional, or 2D TMDC, as they are only a few atoms thick. The ability to produce more electricity per weight compared to traditional silicon solar cells makes them highly suitable for sending into space to harvest the Sun’s energy, according to the researchers. “High specific power is actually one of the greatest goals of any space-based light harvesting or energy harvesting technology,” said Deep Jariwala from the University of Pennsylvania. “This is not just important for satellites or space stations, but also if you want real utility-scale solar power in space. The number of [silicon] solar cells you would have to ship up is so large that no space vehicles currently can take those kinds of materials up there in an economically viable way.” By modelling the innovative solar cell computationally, Professor Jariwala and his team were able to come up with a design that has double the efficiency compared to what had previously been demonstrated. A paper detailing the research, titled ‘How good can 2D excitonic solar cells be?’, was published in the scientific journal Device on Tuesday. The researchers now hope to figure out how to achieve large-scale production for the design. “I think people are slowly coming to the realisation that 2D TMDCs are excellent photovoltaic materials, though not for terrestrial applications, but for applications that are mobile, more flexible, like space-based applications,” said Professor Jariwala. “The weight of 2D TMDC solar cells is 100 times less than silicon or gallium arsenide solar cells, so suddenly these cells become a very appealing technology.” The concept of space-based solar arrays was first theorised more than 50 years ago, with scientists noting that the Sun’s energy could be converted into microwaves and beamed down to ground-based receiving stations that convert them into electricity. It has several advantages over terrestrial setups, as they would not be limited by cloud cover or the Sun’s typical cycle. Research has accelerated in recent years following several major breakthroughs and developments with solar energy harvesting and orbital rocket launches, including the emergence of private space companies like SpaceX that have significantly reduced the cost of delivering payloads into space. Last month, Japanese space agency JAXA announced that it was aiming to set up the first satellite transmitters for a commercial-scale solar farm in space by 2025. The European Space Agency is also planning to establish a development program for this untapped renewable energy resource through its Solaris programme.
