Researchers funded by the US Air Force are developing a new type of device that can invite comparisons to a weapon used by a Batman villain. Scientists, including Patrick Hopkins from the University of Virginia in the US, are working on a new device to be used for on-demand surface cooling for electronics inside spacecraft and high-altitude jets. The device may seem similar to the freeze gun used by Batman villain Mr Freeze to “ice” his enemies. “A lot of electronics on board heat up, but they have no way to cool down,” said Dr Hopkins, whose lab has been granted $750,000 over three years to develop the technology. On Earth, electronics in military craft can rely on nature to cool themselves, but in space, this may be a challenge, scientists said. Citing an example, researchers said the Navy uses ocean water in its liquid cooling systems while flying jets can rely on air that is dense enough to help keep components chilled. “With the Air Force and Space Force, you’re in space, which is a vacuum, or you’re in the upper atmosphere, where there’s very little air that can cool,” Dr Hopkins said. “So what happens is your electronics keep getting hotter and hotter and hotter. And you can’t bring a payload of coolant onboard because that’s going to increase the weight, and you lose efficiency,” he explained. In such extra-terrestrial environments, a jet of plasma, the fourth and most common state of matter in the universe, can be used in the interior of a craft. “This plasma jet is like a laser beam; it’s like a lightning bolt. It can be extremely localized,” Dr Hopkins explained. One of the strange qualities of plasma is that while it can reach temperatures as hot as the surface of the Sun, it chills before heating when it strikes a surface. In the new research, published recently in the journal ACS Nano, scientists fired a purple jet of plasma generated from helium through a hollow needle encased in ceramic, targeting a gold-plated surface. When researchers turned on the plasma, they could measure temperature immediately at the point where the plasma hit, and could see that the surface cooled first and then heated up. “We were just puzzled at some level about why this was happening, because it kept happening over and over,” Dr Hopkins said. “And there was no information for us to pull from because no prior literature has been able to measure the temperature change with the precision that we have. No one’s been able to do it so quickly,” he said. The strange surface-cooling phenomenon, according to scientists, was the result of blasting an ultra-thin, hard-to-see surface layer, composed of carbon and water molecules. Researchers compare this to a similar process that happens when cool water evaporates off of our skin after a swim. “Evaporation of water molecules on the body requires energy; it takes energy from body, and that’s why you feel cold. In this case, the plasma rips off the absorbed species, energy is released, and that’s what cools,” the researchers explained. Using the method, scientists could reduce the temperature of the setup by several degrees for a few microseconds. While this may not be dramatic, they said it is enough to make a difference in some electronic devices. Now, thanks to the Air Force grant, researchers are looking at how variations on their original design might improve the apparatus. “Since the plasma is composed of a variety of different particles, changing the type of gas used will allow us to see how each one of these particles impact material properties,” researchers said.

McDonald’s and Crocs are joining forces to make spicy shoes inspired by the fast-food chain’s animated characters. In partnership with the notable footwear company, the popular creator of the mouthwatering McFlurry is releasing four limited-edition sandals available on 14 November. The special collection will feature three traditional Crocs alongside slip-ons in the brand’s colour scheme (red and yellow) as well as options made to look like Grimace, Hamburglar, and Birdie. “McDonald’s and Crocs are introducing their first-ever collab. Inspired by both Crocs Stars and Mickey D’s loyalists, the collab will drop with a full line of shoes, socks and Jibbitz charms beginning tomorrow in countries around the world,” Crocs announced in its press release, adding that the collection will go live midday. “From a Classic Clog with a McDonald’s spin to a throwback, limited-edition collection inspired by iconic McDonald’s characters – Grimace, Birdie and Hamburglar – the new shoes are designed to give consumers a way to live out their bold fandom every day,” it continued. A layer of potent purple fur will line the inside of the Grimace sandals, while the outer rubber straps will feature the footwear brand’s iconic punctured holes to place themed Jibbitz in. Meanwhile, the Birdie design will be adorned with plastic pink bows, her white goggles, and matching insoles. Then, in true Hamburglar fashion, the Crocs will be detailed with black and white strips, popout masked eyes, and yellow soles. In addition to the McDonald’s emblem – the golden arch – a pack of french fries, a soda cup, a carton of McNuggests, and a Big Mac will be available as Jibbitz add-ons. Each unique pair will retail between $70 and $75, with optional coordinating socks for $20. The entire collection will be sold at Crocs stores as well as select wholesale locations. While the McDonald’s and Crocs collaboration is certainly a tasty treat, the humourous line follows the shoe company’s edgy drop a little over a month ago. On 5 October, Crocs fused a Western aesthetic with dark grunge to come up with its very own cowboy boot. The “foul” shoe was lengthy yet bendable, with two spurs lining the faux leather shaft. Careful stitching and a textured vamp mirrored a classic cowboy boot but was still reminiscent of the brand’s love for funky design. These $120 boots, made in accordance with “Croctober,” the time of year when the brand releases a new style, riled up fans online, eager customers debating harsh critics over the inventiveness and look of the spongy boots. “Why...why do I not hate these?” one person questioned, while another said: “Crocs released cowboy boots. That’s enough internet for today.” Read More The Wrong Coat? You’re bang on trend my friend Chrissy Teigen has hilarious reaction to wardrobe malfunction at Baby2Baby Gala

Martin Brundle might have the most thankless task in all of broadcasting which has been further exemplified by an interaction with basketball legend Shaquille 'Shaq' O'Neal. As is customary at every grand prix, the Sky Sports reporter attempts to speak to the biggest names and celebrities that are in attendance at that particular race. This weekend saw the Las Vegas grand prix take place which was won by Max Verstappen but it's often the celebrities that steal the show and this time it was Shaq's turn. Brundle had attempted to have a few friendly words with the NBA icon who was a guest of Red Bull on the grid. However, the 7ft 1in colossus was in no mood for talking and was more eager to pose for photos. Brundle stood his ground though and waited for Shaq to finish and as the 51-year-old strode past he managed to get a microphone in the former LA Lakers stars' face. However, Shaq response was a lot shorter than his size, only saying "Lewis Hamilton baby" in response to the reporter. Brundle sarcastically responded with: "Lewis Hamilton, baby. That’ll cover it,.” The veteran reporter added: “Yeah, it’s okay. I’ve had a great television career so, honestly, it doesn’t really matter, does it, if it’s over this evening?” Although Brundle is used to these type of awkward interactions with major stars it still didn't stop people from thinking that Shaq's behaviour was rude and ignorant. Brundle has also had awkward run ins on F1 grids with the likes of Machinegun Kelly, Cara Delevingne, Megan Thee Stallion and Brad Pitt. He has had some fun on the grid recently, such as when he met Eurovision legend Sam Ryder.

Further storms are set to batter a Greek island where hundreds of British tourists are stranded following flash floods. At least one person was killed and five others are thought to be missing after cars were swept away and streets submerged by rainfall in parts of Greece on Tuesday. It comes as the World Meteorological Organisation said that the northern hemisphere experienced its hottest summer on record, fuelled by climate change. Skiathos, a popular holiday island in the northwest Aegean Sea, was forecast to be hit with heavy showers and thunderstorms throughout Wednesday morning. Holidaymakers on the island have been left with “no way to get food” with many currently unable to get to the airport. One stranded tourist said the centre of Skiathos is “underwater” and described the situation as “horrendously scary”. Flooding is also affecting parts of Turkey and Bulgaria with the death toll across the three countries currently at 11.
