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.

Google has unveiled a major new update to its AI chatbot Bard that significantly improves its powers of logic and reasoning. The latest version of the ChatGPT rival is now capable of both writing and executing code by itself, the tech giant announced, allowing it to figure out problems on a far deeper level than current generative AI systems. Google’s artificial intelligence tool is able to perform the new tasks through a new technique called “implicit code execution”, which enables Bard to detect computational prompts and run code in the background. The result is that Bard should theoretically be able to respond more accurately to mathematical tasks and coding questions, as it will have already tested the outcomes that it proposes. Until now, large language models (LLMs) like ChatGPT and Bard have been better suited to language and creative tasks, as they draw from their training data to predict what word will come next when talking about a specific subject. This allows them to produce text quickly but without deep thought, making them weaker when it comes to areas like reasoning and mathematics. “Our new method allows Bard to generate and execute code to boost its reasoning and maths abilities,” Google wrote in a blog post on Wednesday. “With the latest update, we’ve combined the capabilities of both LLMs and traditional code to improve accuracy in Bard’s responses. Through implicit code execution, Bard identifies prompts that might benefit from logical code, writes it ‘under the hood,’ executes it and uses the result to generate a more accurate response.” The new method improved Bard’s accuracy for coding and maths problems by roughly 30 per cent during internal tests, Google claimed. Accuracy remains one of the biggest issues with AI chatbots, with Google warning that despite the upgrade, Bard “won’t always get it right”. Unreliable or fabricated information generated by these AI tools is known as hallucinations, and they are typically delivered in a confident way that can be even more misleading for the user. ChatGPT creator OpenAI announced a potential new method to improve AI misinformation last month, involving two AI systems debating each other until they agree on the correct answer.
