NASA has initiated the process of returning its massive Space Launch System (SLS) rocket and Orion spacecraft to the launch pad at Kennedy Space Center in Florida. This move comes after completing necessary repairs, setting the stage for a potential launch on April 1.The operation, which can take up to 12 hours, began at 8pm local time. The rocket and spacecraft will be moved 4 miles (6.5km) to launch pad 39B. If all tests are satisfactory, the mission will proceed with a crew of three US astronauts and one Canadian set to fly around the moon.This mission, expected to last about 10 days, marks a significant step towards achieving the goal of returning humans to the lunar surface. The Artemis 2 mission had faced several delays, including issues with helium flow and a liquid hydrogen leak during a previous wet dress rehearsal.The Artemis 2 astronaut crew entered quarantine in Houston as they prepare for liftoff. With the April 1 launch window approaching, NASA remains hopeful that this mission will successfully launch in early April, paving the way for future lunar exploration.

Researchers at Cortical Labs in Melbourne have created a 'biological computer' using living human tissue, which can play the 1993 shooter game Doom. The team used 10ml of blood from CEO Hon Weng Chong to harvest 100 white blood cells, which were then reprogrammed into induced pluripotent stem cells (iPSCs). These cells were used to create a dish of 200,000 neurons that can interface with a computer system.The brain cells were taught to play Doom by encoding game state information, passing it through a neural network, and converting it into signals the neurons can understand. The neurons then fire an output, which the system decodes and converts back into actions in the game. This process is similar to how humans operate, with information going into the retina, being converted into electrical signals, processed in the brain, and resulting in an output.While the achievement has sparked concerns about sentience and consciousness, Chong believes the brain cells are not conscious, stating, 'At first it didn’t know how to move, aim or shoot. Then it would shoot two enemies and stop. So it’s definitely learning.' The next step could be integrating this technology with Neuralink, a brain-machine interface developed by Elon Musk.The application of biological computing lies not in gaming, but in medicine, such as disease modeling for conditions like epilepsy. This technology could allow for personalized drug testing and tailored treatments. Meanwhile, Eon Systems in San Francisco has created a virtual insect brain that can behave like a real fly, challenging the assumption that intelligence must be acquired.Biological systems like these could eventually power robots, drones, and other machines that need to navigate complex environments. As Chong notes, 'Abstract reasoning, mathematics and language are relatively recent in evolutionary terms... but motor control and probabilistic decision-making are things we’ve inherited through millions of years of evolution.' While we're far from uploading human consciousness into the internet, this technology marks a significant step in the development of biological computing.
