Every month, the uterus builds an entire new layer of tissue, prepares it for a possible pregnancy, then starts all over again. Billions of people experience this cycle, yet there’s still a surprising amount we don’t understand about it. #kurzgesagt #inanutshell #Science #menstrualcycle #pms #femalehealth

• Panspermia is the hypothesis that life on Earth did not originate spontaneously (abiogenesis) but was instead brought here from outer space in the form of biological "seeds." This idea proposes that microorganisms, extreme-resistant spores, or complex organic precursors are capable of traveling through interplanetary or interstellar space aboard comets, meteorites, and cosmic dust. Upon landing in favorable conditions on a new planet, these cosmic hitchhikers can initiate biological evolution. Notably, panspermia does not solve the mystery of how life initially emerged in the universe; it merely shifts the starting point of genesis from early Earth to another cosmic location. Within the scientific community, the concept is generally divided into two main categories: natural (lithopanspermia) and directed (intentional). Lithopanspermia suggests that rock fragments blasted off the surface of a life-bearing planet (such as ancient Mars) by powerful asteroid impacts can drift through the vacuum of space and accidentally collide with other celestial bodies. This theory is supported by actual discoveries of Martian meteorites on Earth (like ALH 84001) and the proven extreme resilience of certain terrestrial organisms — such as tardigrades, Deinococcus radiodurans bacteria, and fungal spores — which can survive years of cosmic radiation, hard vacuum, and freezing temperatures, while also enduring the crushing pressures and heat of atmospheric entry. Conversely, directed panspermia—a concept famously co-proposed by DNA co-discoverer Francis Crick—explores the scenario where life was intentionally sent to a young Earth by an advanced alien civilization. In the 21st century, as amino acids and complex hydrocarbons are continuously found inside comet tails and meteorites (such as the Murchison meteorite), a variant known as pseudopanspermia (or molecular panspermia) has gained significant traction. This view argues that space delivers not living organisms, but ready-made organic building blocks, which dramatically accelerated chemical evolution in our planet's primordial oceans. #scary #facts #life #Science@ʜᴏʟᴠᴇᴋ
• There is a natural direction to almost everything happening around us. A warm cup slowly cools, ice turns into water, and energy gradually spreads through a system. These simple processes are connected by the same fundamental principles of physics. What makes this especially fascinating is that we have learned to locally influence that direction. A refrigerator, for example, uses energy to move heat from a colder space into a warmer environment, allowing us to maintain specific conditions for long periods of time. Nature does something similar in incredibly complex ways. Living cells constantly use energy to maintain their structure, build molecules and organize countless processes at once. From a glass of water to living organisms and entire stars, the same physical principles appear at completely different scales. And somehow, that is incredibly beautiful. #Natural #nature #Energy#Science #edit@pitochk
