SpaceX rolled out its Booster 7 prototype of the Super Heavy rocket to its launch site on Thursday. It was lifted using the chopsticks on the launch tower and placed on its launch mount. The booster will go through pressure testing and potentially a static fire test in the coming days or weeks. Elon Musk has been pushing for an orbital launch attempt in July.

Apple's VR/AR headset will be released in January 2023, according to Apple insider Ming-Chi Kuo. The mixed reality headset will be the most complicated product Apple has ever designed. It will be a premium product with very high-fidelity displays, Apple silicon power, and a very hefty price tag. The launch of the headset will likely lead to rapid growth in the industry.

A group of researchers has developed a way to create food without sunlight using artificial photosynthesis. The method involves converting carbon dioxide, electricity, and water into acetate, and then feeding the acetate to food-producing organisms in the dark to grow. It is up to 18% more efficient for some organisms. The method can be used to grow green algae, yeast, fungal mycelium, tomatoes, rice, and green peas. It could be used to grow crops in areas currently unsuitable for agriculture.

While CRISPR is one of the most groundbreaking inventions of the century, it has a relatively high error rate that can produce potentially harmful mutations. Researchers from Germany have developed a tool that reduces errors by nicking DNA instead of cutting it. The tool makes two smaller cuts, one on each DNA strand, rather than slicing through the entire double strand of DNA. The new method is about as effective at making edits as conventional CRISPR and it significantly reduces on-target mutation errors.

OpenAI used a mix of video training and reinforcement learning to create an AI that can make a diamond pickaxe in Minecraft. Creating a diamond pickaxe in Minecraft is a complex task that requires many steps. The team used a method called Video PreTraining (VPT) that involved training the AI using massive amounts of raw gameplay video and human-processed video. VPT can be used for almost any software where there is enough video material.

Scientists have discovered life in the extremely cold and salty waters of the Lost Hammer Spring in the Canadian Arctic. The microbes had adaptations that allowed them to thrive in water with temperatures of around minus five degrees Celsius, less than one part per million of dissolved oxygen, and around 24% salinity. They don't depend on organic material or oxygen to survive. Similar environments may exist on ocean worlds like Jupiter's moon Europa and Saturn's moon Enceladus.
