NO.1 SpaceX Starship to Conduct Fourth Test Flight Tonight

SpaceX, under Elon Musk’s leadership, has received regulatory approval to conduct the fourth test flight of the Starship on June 6th. The launch window is set for a 120-minute period starting at 20:00 Beijing time tonight (Thursday). This test flight will focus not on reaching orbit but on demonstrating the capabilities of the Starship and the Super Heavy rocket to return and be reused. To achieve this, SpaceX has made several software and hardware upgrades to enhance overall reliability, learning from the experiences of the third flight test.

Commentary: SpaceX’s Starship project continues to advance, with this test flight focusing on testing the return and reuse capabilities of the Starship, a key step towards achieving its long-term goals for space exploration.

NO.2 Musk Redirects AI Chips Reserved for Tesla to Company X

According to international media reports, internal emails from Nvidia suggest that Elon Musk is redirecting a large quantity of Nvidia H100 AI chips, originally reserved for Tesla, to his social media company X. This move could delay Tesla’s receipt of over $500 million worth of chips by several months, potentially causing delays in the installation of supercomputers needed for the development of autonomous vehicles and humanoid robots.

Commentary: Musk’s reallocation of Nvidia H100 AI chips reserved for Tesla to Company X may impact the development of Tesla’s autonomous driving technology. However, it also demonstrates Musk’s flexibility in resource allocation across different sectors.

NO.3 Artificial Neural Network Accurately Predicts Male Fruit Fly Courtship Behavior

A new study published online in the British journal Nature reports that American researchers have trained an artificial neural network that can simulate the visual neural system of male fruit flies, accurately predicting their behavior when they see potential mates. This strategy, known as “knockout training,” helps understand how real neural circuits work. The artificial neural network, developed by researchers from institutions like Princeton University, reveals the transformation mechanism from the visual information received by the male fruit fly to neuron activity and then to behavior.

Commentary: This study uses an artificial neural network to simulate the visual neural system of fruit flies, successfully predicting their courtship behavior and providing a new perspective on understanding animal neural circuits.

NO.4 Study: A Diabetes Drug Helps Clear Aging Cells in Lab Mice

A press release from Juntendo University in Japan announced that a team, including researchers from the university, successfully used a diabetes drug to clear some aging cells in lab mice. This not only improved symptoms like metabolic abnormalities and arteriosclerosis but also extended the lifespan of mice with progeria. The team fed the mice a high-fat diet to induce weight gain, then treated them with a short-term course of sodium-glucose cotransporter-2 inhibitors (SGLT-2 inhibitors). The results showed that aging cells accumulated in the visceral fat of the mice were cleared, and inflammation, glucose metabolism disorders, and insulin resistance were all improved.

Commentary: The Japanese research team’s use of a diabetes drug to clear aging cells in lab mice improved metabolic abnormalities and extended lifespan, offering new possibilities for treating age-related diseases.
