Q&A: 'Killer robots' are coming, and UN is worried
2024-01-15 21:53:30
Long the stuff of science fiction, autonomous weapons systems, known as "killer robots," are poised to become a reality, thanks to the rapid development of artificial intelligence.
Researchers develop thin film as resistance-switching material for next-generation memristive devices
2024-01-15 18:48:16
Memristive devices are capable of retaining their internal resistance, thus offering superior performance compared to conventional devices that use integrated circuits. Several materials have been explored for the manufacture of these devices. In recent years, transition metal oxides have gradually become widely popular for this purpose.
NASA, Lockheed Martin reveal X-59 quiet supersonic aircraft
2024-01-15 18:48:16
NASA and Lockheed Martin formally debuted the agency's X-59 quiet supersonic aircraft Friday.

Revisión de sorbentes de cambio de humedad para la captura de dióxido de carbono del aire ambiente
2024-01-15 17:38:36
Recientemente se han logrado avances en la tecnología de captura de carbono que podría permitirnos absorber eficientemente el dióxido de carbono directamente del aire y tal vez detener el aumento de las concentraciones atmosféricas del gas de efecto invernadero.El desarrollo de absorbentes de humedad como tecnología en esta área se analiza en un artículo publicado en el International Journal of Global Warming.
Not all carbon-capture projects pay off—Research maps the pros and cons of each to find clear winners and losers
2024-01-15 17:38:36
Capturing carbon dioxide from the air or industries and recycling it can sound like a win-win climate solution. The greenhouse gas stays out of the atmosphere where it can warm the planet, and it avoids the use of more fossil fuels.
Data brokers know everything about you—what the FTC case against ad tech giant Kochava reveals
2024-01-15 17:38:36
Kochava, the self-proclaimed industry leader in mobile app data analytics, is locked in a legal battle with the Federal Trade Commission in a case that could lead to big changes in the global data marketplace and in Congress' approach to artificial intelligence and data privacy.
Can Texture2D save images with transparent background? Can we use Texture2D with transparent background directly to achieve the effect of transparent image overlaying in Metal shade?
2024-01-15 17:26:25
Texture2D can save images with a transparent background. In Texture2D, a separate alpha channel is typically used to describe the transparency of background pixels. In Metal’s fragment shader, colors and alpha values of each pixel can be obtained by sampling the texture, and they can be used for subsequent processing.
