Have you ever felt like you're racing against the clock, constantly chasing appointments and deadlines? This relentless pursuit of time is a universal experience, but what is time, really? Is it a physical phenomenon or just a tool we use to coordinate our lives? Time is often seen as an independent, physical entity that ticks by relentlessly, but emerging scientific evidence suggests that this isn't the case. Time is more like a mathematical tool, useful for coordinating our interactions, but it doesn't have an independent existence of its own. Just like money, we've become dependent on it, but it's not a physical reality. The pressure to be 'on time' is instilled in us from a young age, and we're constantly surrounded by clocks and digital alerts that divide our day into smaller pieces. This has led to a phenomenon known as 'time famine,' where the more efficient and productive we try to be, the less time we feel we have. Studies have shown that people experiencing time famine are less likely to engage in activities they enjoy, eat healthily, or seek medical attention when needed. Our brains don't have dedicated areas for tracking time, and our experience of it can vary greatly. Time can seem to drag or fly by, depending on our circumstances. For example, people with certain conditions, like akinetopsia, experience time in sudden jumps or frozen moments. The psychedelic drug mescaline can also distort time perception, making it seem like hours or even centuries have passed. Quantum physicists have found that time is not a fixed, physical flow. The famous double-slit experiment shows that a physicist's choice of measurement can influence the behavior of a particle. In a lesser-known variant of this experiment, the physicist's choice at the point of measurement can even influence the particle's past behavior. This suggests that time is not a fixed, linear concept, but rather a flexible and subjective experience. Some indigenous cultures, like the Aymara people of Chile, experience time differently. They see the future as hidden behind them, unseeable and unknowable. The Amondawa people of the Amazon have no clocks or concept of time. Instead, they live in the present, experiencing 'lived time,' which is a personal, malleable experience of change. Lived time is different from clock time, as it's not defined by numerical counters or seconds. Each moment is like a tapestry, woven from changes on multiple timescales. When we focus on lived time, it expands and becomes richer, rather than narrowing or contracting. It's a flow that carries us and connects us with others, rather than something we chase and never catch. To combat time famine, we need to remind ourselves that the clock is a tool, not a master. We should beware of digital alerts and alarms that divide our day into smaller pieces and instead focus on the rich pattern of changing connections that wire us into each moment. By doing so, we can tap into the creative process of lived time and experience a more fulfilling and connected life.

Scientists have made a groundbreaking discovery that could lead to the development of new obesity drugs. By studying the unique metabolic abilities of pythons, researchers have identified a molecule that appears to play a crucial role in regulating appetite and weight loss. The molecule, called pTOS, was found to increase significantly in the blood of pythons after they eat, and when administered to obese mice, it led to a significant reduction in food intake and a 9% loss of body weight over 28 days. The discovery could lead to the development of new obesity drugs that work in a different way to existing medications, such as GLP-1 medications like Wegovy. Unlike these medications, which can have side effects such as nausea and stomach pain, pTOS appears to act on the brain's appetite centers, reducing food intake without these adverse effects. The researchers, led by Dr. Jonathan Long from Stanford University and Prof. Leslie Leinwand from the University of Colorado Boulder, published their findings in the journal Nature Metabolism. They believe that pTOS, which is naturally produced by the snake's gut bacteria and also found in human urine, could be a safe and effective treatment for obesity. While further research is needed before the findings can be applied clinically, the discovery is seen as a promising step towards the development of new obesity treatments. The study's results suggest that pTOS could be a potential therapeutic target for the treatment of obesity and related metabolic disorders.

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.
