- no biological aging during childhood years, characterized by using calcium, iron and copper in making new bones, red blood-cells and collagen;
- accumulation of minerals once childhood growth ceases and progressive aging as evidenced by buildup of lipofuscin;
- slight decline in the rate of aging in late life, which has been correlated with reaching a steady state of minerals.
Single high dose of the hallucinogen psilocybin, active ingredient of “magic mushrooms,” was enough to cause a measureable personality change lasting at least a year in nearly 60% of the 51 participants, according to a new study.
Personality was measured on a scientifically validated personality scale, which psychologists consider constituents of personality: openness, extroversion, agreeableness, neuroticism, conscientiousness.
Lasting change was found only in “openness,” which includes traits related to imagination, aesthetics, feelings, abstract ideas and general broad-mindedness.
Researchers will now explore possibilities of using psilocybin for helping cancer patients handle the depression and long-time cigarette smokers to overcome their addiction.
Hip-hop, an artistic expression/culture formed during 70s in Bronx, is a combination of terms — “hip” was used in African-American vernacular English starting in 1898, meaning current or in the know, and “hop” from “to hop.”
Hip-hop was the creative coalescence of the then popular funk music, self-appointed disk-scratching DJs, break-dancing MCs, improv lyricist-rappers and complementary street art (graffiti) which visualized a culture tinged with social bias, racism and ethnic rebellion. It went mainstream in 1979 by “Rapper’s Delight.”
Creativity in street (hip-hop) and classic (jazz) musical traditions is now being employed by neuroscience in exploring brain performance during creative processes.
4.5 billion years of evolution taught nature what works and what lasts.
We’ve been increasingly distancing ourselves from nature: agricultural revolution – grow stock and abandon hunting/gathering; scientific revolution – “torture nature for her secrets;” industrial revolution – machines replace muscles.
- use only the energy needed
- fit form to function
- recycle everything
- curb excesses from within
- tap the power of limits
- devise systems that can face unknown situations
- update ourselves by feedback loops
Humans are more closely related to fungi than other kingdoms. Humans share same pathogens with fungi. Fungi don’t like rot from bacteria – our best antibiotics come from fungi. Fungi don’t need light, using radiation as energy source.
Fungi were first (1.3 billion years) organisms on Earth. Plants followed few hundred million years later.
Mycelium reduces oxalic acids/enzymes that pockmark rocks, forming calcium oxalates from minerals and CO2. First step to soil creation. Mycelium also converts cellulose into fungal sugar (ethanol).
Stats about our universe (in 199 words – didn’t make sense to split):
- there are 200 billion stars in Milky Way;
- age of universe between now and Big Bang is about 100 billion dog years;
- universe was very smooth in the distant past;
- entropy is the number of ways we can rearrange the constituents of a system so that it looks the same macroscopically;
- entropy increases (2nd law of thermodynamics) because there are many more ways to be high entropy than to be low entropy;
- every difference between past and future is because of increased entropy: that we can remember past but not future;
- 380.000 years after Big Bang, hydrogen and helium nuclei captured electrons to form stable atoms;
- gravity started compacting helium and hydrogen clouds, and once temperatures exceeded 10 million degrees, protons started fusing -there was a huge release of energy – the first star was born;
- from about 200 million years after the Big Bang, stars started appearing through the universe.
- when large stars die, they create temperatures so high that protons start fusing into all sorts of combinations creating new types of atoms.
- Goldilocks’ conditions of life: right amount of energy, diverse chemical elements, liquids (water).
- 1 billion years ago, first multicellular organism appeared.
