This article explores the unique nature of friendships and the science behind them. It discusses how friendships formed during adolescence are particularly special due to changes in the brain’s reward center and improvements in Theory of Mind. It also highlights the concept of interpersonal synchrony and how it contributes to the deep connections we form with our closest friends.
This article explains the science behind touchscreens, discussing the different types of touchscreens and how they work. It also explores how the human body interacts with touchscreens and the challenges of using touchscreens with wet hands or while wearing gloves.
The article discusses the field of art conservation and highlights three cases where art conservators have successfully recovered original masterpieces that had been altered over time. The cases include uncovering the true face of a 16th-century portrait, restoring the provocative details of a Bronzino painting, and reconstructing missing sections of Rembrandt’s “The Night Watch.” The article emphasizes the importance of art conservators in preserving priceless artifacts for future generations.
The article discusses the Boltzmann brain paradox, which is the question of whether our lives and memories are real or just illusions. It explores Ludwig Boltzmann’s interpretation of entropy and his application of statistical reasoning to thermodynamics. The paradox arises in an infinitely old universe, where it is more likely for complex structures like brains to form randomly than for our current existence to be real. The resolution to the paradox lies in the Big Bang theory, but contemporary cosmologists still debate the likelihood of Boltzmann brains and their implications for the origin of the universe.
A year ago, scientists discovered an underground city on Mars, providing evidence of intelligent alien life. However, they lost contact with Earth and are now facing a water shortage. They have uncovered clues in the city’s pyramids about how the ancient civilization survived, including a lever that could bring water back to the surface, but the location of the lever remains a mystery. The scientists now face the decision of whether or not to pull the lever and potentially save their lives.
The article discusses the challenges of treating the common cold, highlighting the rapid mutation of the virus that can outmaneuver years of research and development. It explains that the common cold is caused by many different viruses, making it difficult to find a cure, but suggests that targeting the rhinovirus, which causes a significant portion of colds, could be a step towards finding a cure. The article also mentions the challenges of developing vaccines and antiviral drugs, but remains hopeful for future breakthroughs, such as the potential use of CRISPR as an antiviral agent.
The article discusses the concept of a universal vaccine that could protect against all diseases. It focuses on the development of a universal flu vaccine that could protect against all strains of the flu, including future ones. The article explores the challenges in vaccine development, the design of a universal vaccine, and emerging science in the field. While a fully universal vaccine against all infectious diseases is currently beyond our reach, the article suggests that advancements in medical technology could bring us closer to this goal in the future.
The article discusses the reality of pandemics and the probability of future pandemics. It highlights that pandemics are not as unlikely as we may think, with several global pandemics occurring in recent history. The article also explores different ways to estimate the likelihood of future pandemics and emphasizes the importance of reducing the risk through measures such as early warning systems, contact tracing, and vaccines. It concludes by stating that we have the power to change these probabilities and must take the threat seriously to create a safer future.
The article discusses the history of the plague, one of the most terrifying and destructive diseases in human history. It explores the iconic image of the European plague doctor and their outfit, which was believed to protect against the spread of the disease. The article also mentions the medical practices used during the plague and highlights the advancements in modern medicine.
