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.

Bethesda has vowed to make 'Redfall' the game it should have been after a disastrous launch.

It may only be September with 112 days to go until Christmas – but it seems Mariah Carey is defrosting early, with 'All I Want For Christmas' sneaking its way into the charts. A fan page on X/Twitter highlighted some stats that claimed the hit single received 316,000 Spotify streams on 1 September – a 75 per cent increase "compared to the same day in 2022". Carey soon responded to the tweet, passionately writing: "Not yet!!!!" She continued: "I'll allow it for my Filipino lambs though! (I don't make the rules!) The star was referencing the Philippines tradition in which Christmas starts as soon as the year hits the 'BER' months (September, October, November, and December.) "Every year, from the 1st of September, decorations will be put up around the country and the festivities will begin. You'll even start to hear Christmas songs in all the malls, restaurants and on the radio," Travel Continuously explained. Eager fans flooded Carey's tweet, with one writing: "This is my alarm song every day of the year. Say something!" "She’s the mother of Christmas," another added, while a third shared: "We haven't even celebrated HALLOWEEN yet, people!! Slow down before we get to Mariah Carey Season." The 1994 single may be a hit solely for Christmas, but it is estimated to bring in around $2.5million every single yea $2.5million every single year. In fact, by 2016 it's thought that Mariah Carey had earned around $60million from the song - a figure set to be even higher now.

Fantasy Premier League managers get one free transfer a week to make but with the competition in full flow some may have saved up for two free switches to their teams while others will be considering a four-point hit or more to maximise the chances of success. Here are five players who we think are worthwhile considering as the Premier League heads into the new gameweek, judging by upcoming fixtures and individual player form. Destiny Udogie, Tottenham - Defender (4.7) In his last three matches, the defender has recorded 22 points, making him a good option for those looking to move some things around and free up some money in their team. He has already notched up two assists this season, and Spurs’ next match is against Sheffield United, although rotation may be expected with Liverpool and Arsenal to come afterwards. After those two difficult matches however it is a good run for Tottenham going forward. Udogie could be a high-scoring option, especially if there is flexibility to rotate him out for the difficult matches. Bryan Mbeumo, Brentford - Midfielder (6.8) Mbeumo has enjoyed an impressive start to the season, averaging 8.2 points per match and has already scored four goals. While Newcastle away next week might be a tough ask for Brentford, there are matches against Everton and Nottingham Forest afterward. While not necessarily a cheap option, he can offer a more affordable option than other midfielders. Julian Alvarez, Manchester City - Forward (6.7) Forwards, and in particular Manchester City forwards often come with a high price tag, which makes Alvarez a relative bargain. He has averaged seven points a match, scoring two goals and recording three assists, especially during his 14 points during City’s dominant 5-1 win over Fulham at the weekend. With City’s next three fixtures coming against West Ham, Nottingham Forest and Wolves it could also be the ideal time to add in some extra support. James Maddison, Tottenham - Midfielder (7.8) Tottenham have won their last three matches, so on paper they look strong and it’s the right time to add their players to a squad. Maddison has been outstanding since joining the club, averaging 7.2 points a match, scoring two goals and providing two assists. It is a high price tag but could be worth the investment in the long run. Alphonse Areola, West Ham - Goalkeeper (4.1) Areola was known for his shot-stopping abilities when he was at Fulham, and seems to have taken over the number one spot at West Ham this season. As goalkeepers go he is a cheap option at just 4.1 million but he has averaged five points a match, including a memorable 10 points during the second gameweek against Chelsea. At a minimum, he is guaranteed to play every week, and with West Ham’s impressive start to the season he could be a good addition if the rest of your budget is allocated in other positions. The Hammers face Man City at home and Liverpool away next, but Areola could be a cheap option to pair with a more expensive goalkeeper who has difficult fixtures in gameweeks seven and eight, with the potential to score points against Sheffield United at home and Newcastle at home.
