James Webb Space Telescope shows Uranus’ unique tilt and extreme seasons
The Webb Telescope is the successor to NASA’s Hubble Space Telescope, which has operated since 1990. Unlike Hubble, which primarily captures visible and ultraviolet light, the Webb telescope is designed to capture infrared light, which allows it to see through dust and gas clouds that obscure visible light. Despite some early technical difficulties, including a…

‘First’ browser with DALL-E-powered AI image generator
“Edge is now the first and only browser with an integrated AI image generator.” The “Image Maker” will be accessible when it launches through Edge’s sidebar. Bing will produce several images corresponding to the prompt after simply typing in the desired image. The chosen photographs can then be downloaded and used however the user pleases.…

Google CEO confirms that chatbot AI is coming to Google Search
Google, the world’s most widely used search engine, responds to billions of inquiries daily by providing information and links. Adding AI conversation to Google Search would make the technology more widely used and move it from an experiment to a standard way to find information. Moreover, this won’t be the first time Google has experimented…

Gordon Murray Automotive unveils its new supercar
The heart of the T.33 Spider is the Cosworth GMA.2 V12, an all-aluminum powerplant designed according to motorsport principles in partnership with Cosworth. The engine is dry-sumped, 3.9 liters, and features a 65-degree cylinder bank angle for optimum packaging within the monocoque and contributing to the car’s low center of gravity. The exhaust manifolds are…

Making drones suitable for cities
With technology for drones far advanced, the next step is to ensure they can fly safely in cities. Credit: CC0 via Unsplash Unmanned aerial vehicles will make their way into urban skies only if the safety of people below can be ensured. The Spanish resort town of Benidorm is known for its sandy beaches with…

False memories can form in the human brain in just seconds
“It is only when memory becomes less reliable through the passage of a tiny bit of time, or the addition of extra visual information, that internal expectations about the world start playing a role,” according to Otten. Fallible memories aren’t just for childhood or long-ago events While a single study isn’t enough on its own…

Experimental evaluation of soapberry seed oil biodiesel performance in CRDI diesel engine
Combustion study In this combustion studies explained about the in cylinder pressure variations and the heat release rate variation on the engine during the operation at highest load with different biodiesel blends and diesel. From the Fig. 3 mentioned that the maximum pressure obtained at maximum load on the cylinder of 78.93 bar, 79.99 bar, 81 bar and 81.96 bar…

Influence of domain walls thickness, density and alignment on Barkhausen noise emission in low alloyed steels
Mechanical properties The mechanical properties provided in Table 2 were obtained from stress–strain curves depicted in Fig. 2. The true σYS is more as that the minimal guaranteed (the nominal one). The increase in σYS as well as σUS (ultimate strength) is at the expense of the decrease in the elongation at break. The mechanism of…

Freeze–thaw process of soil between two piles as monitored by piezoelectric ceramic sensor
Freezing process of specimens in freeze–thaw cycle The moisture content of the clay samples was 10%, 15%, 20%, 25%, and 30%. When the temperature dropped to 0 °C, the testing times were approximately 72 min, 105 min, 120 min, 150 min, and 156 min, respectively, as shown in Figs. 2 and 3. The moisture content of the medium sand samples was…

Robust, motion-free optical characterization of samples using actively-tunable Twyman–Green interferometry
Focal length characterization of the TFL used for the experiments We characterized the focal length of the TFL as a function of the applied DC current \(I_\mathrm{DC}\) from the Optotune lens driver model 4i. For this purpose, we used a simple setup where a collimated beam was passed through the TFL. The location of the…
