SEOUL, Sept 3 (Reuters) — North Korea conducted a simulated tactical nuclear attack drill that included two long-range cruise missiles in an exercise to “warn enemies” the country would be prepared in case of nuclear war, the KCNA state news agency said on Sunday.

KCNA said the drill was successfully carried out on Saturday and two cruise missiles carrying mock nuclear warheads were fired towards the West Sea of the Korean peninsula and flew 1,500 km (930 miles) at a preset altitude of 150 meters.

Pyongyang also said it would bolster its military deterrence against the United States and South Korea.

Summary: Researchers provided robust evidence supporting the controversial “critical brain hypothesis” through a project called DishBrain.

This experiment, involving 800,000 human neural cells playing Pong, reveals how neurons shift into a “neural critical” state when informed about the surrounding environment, enabling cascades of brain activity. This state lies between the extremes of epileptic excitation and a comatose stall.

The findings hint at profound insights into brain function and potential treatments for neurological disorders.

Organometallic compounds, molecules made up of metal atoms and organic molecules, are often used to accelerate chemical reactions and have played a significant role in advancing the field of chemistry.

Metallocenes, a type of organometallic compound, are known for their versatility and special “sandwich” structure. Their discovery was a significant contribution to the field of organometallic chemistry and led to the awarding of the Nobel Prize in Chemistry in 1973 to the scientists who discovered and explained their sandwich structure.

The versatility of metallocenes is due to their ability to “sandwich” many different elements to form a variety of compounds. They can be used in various applications, including the production of polymers, glucometers—used to measure the amount of glucose in the blood, perovskite solar cells, and as a catalyst, a substance that increases the rate of a chemical reaction without being consumed or changed by the reaction itself.

Scientists have been able to observe a common interaction in quantum chemistry for the first time, by using a quantum computer to shadow the process at a speed 100 billion times slower than normal.

Known as a conical intersection, the interactions have long been known about, but are usually over in mere femtoseconds – quadrillionths of a second – making direct observations impossible to carry out.

Generative AI is dominating the conversation in 2023, and the design community is no exception to its transformative potential. Product innovations fueled by emerging AI capabilities have the potential to unlock new opportunities and put the power of real-time intelligence in customers’ hands like never before.

As a design leader focused on creating innovative products and solutions for millions of our consumers and for thousands of our employees, I find AI’s potential particularly exciting for the design discipline. New technological advances like generative AI, computer vision, natural language processing and large language models can augment, complement and elevate the capabilities of designers, enabling them to focus on work that delivers maximum value to their users. At the same time, there are ongoing and important conversations about designing and implementing new safeguards and frameworks to mitigate risk and ensure the responsible application of AI.

Let’s take a closer look at the dynamic intersection of AI and design, focusing on how AI-enhanced design tools can enhance designer workflows, improve outputs and fuel product innovation.
