# esobio: the Benjamin's hypothesis: looking for Dyson spheres around white dwarfs.

<< Dyson spheres (DSR) are the stuff of highly advanced civilizations, commonly thought of as artificial spheres surrounding an entire star.  (..) any of these configurations would have one unique, tell-tale sign—they would change that star's infrared signature. >> 

Benjamin Zuckerman's << theory focuses on scanning white dwarves for anomalous infrared signatures that might indicate that an artificial construct surrounds them. But why white dwarves? Other than being reasonably ubiquitous, they have the distinction of being the end state of stars like our own. >>️

WISE and Spitzer << watched white dwarves with masses around what we would expect our own sun to turn into. They even noticed some incidences of anomalous infrared signatures. However, the researchers thought dust was the most likely cause of those anomalies, and there was no evidence of any DSR. (..) But the absence of evidence is not evidence of absence—it just helps to constrain the likelihood. (..) According to Dr. Zuckerman, with the observations we have already made, we can do a statistical calculation that less than 3% of habitable planets that orbit stars that eventually turn into white dwarves build a DSR around them. Granted, current estimates put the number of habitable planets around G-type stars that might ultimately evolve into white dwarves at 300 million—so there could still be upward of 9 million civilizations that have built a DSR around their white dwarf home star. But for now, the Fermi paradox still holds, and science continues to collect data that will either further constrain the estimates of the number of advanced technological civilizations in our galaxy or prove that we're not alone once and for all. >>️️

# evol: spontaneous, immediate asymmetry, the chiral twist

<< When holding a right hand in front of a mirror, one can see a reflected image of a left hand and vice versa. In 1848, Louis Pasteur discovered that organic molecules are much like our hands: they come in mirror-image pairs of left- and right-handed variants. Nowadays, we know that this handedness or chirality (from the Greek word for "hand") is a hallmark of organic molecules. >>

<< Organic molecules are rich in carbon atoms, which form bonds to create either a right or a left "nano-hand." Yet, puzzlingly, life almost always selects to exclusively use one of the two mirror-image twins—a phenomenon called homochirality. For example, terrestrial life is based on left-handed amino acids and right-handed sugars. >>️️

<< A model now proposes a novel explanation for the emergence of homochirality in life—a longstanding puzzle about the origin of life on Earth. >>️

<< Homochirality emerges spontaneously in prebiotic chemical networks that adapt to optimize energy harvesting from the environment. Previously, it was believed that chiral symmetry breaking requires multiple loops of auto-catalysis, which increasingly produces one enantiomer of a molecule while inhibiting the formation of the other. However, the IBS team's results showed that the underlying mechanism of symmetry breaking is very general, as it can occur in large reaction systems with many random molecules and does not require sophisticated network architectures. It was found that this sharp transition to homochirality stems from the self-configuration of the reaction network in order to achieve more efficient harvesting of energy from the environment. >>️

# brain: waiting for 'magic strings', psilocybin is a 'relatively safe' drug.

<< Psilocybin-containing mushrooms are used for recreational, spiritual, self-development and therapeutic purposes. However, physiologically relatively nontoxic, adverse reactions are occasionally reported. >>

The << study investigated the 12-month prevalence and nature of magic mushroom-related adverse reactions resulting in emergency medical treatment seeking in a global sample of (9.233) people reporting magic mushroom use. >>️

️

️ << The results confirm psilocybin mushrooms are a relatively safe drug, with serious incidents rare and short lasting. Providing harm-reduction information likely plays a key role in preventing adverse effects. More research is needed to examine the detailed circumstances and predictors of adverse reactions including rarer physiological reactions. >>️

# life: apropos of transitions, a leap from chemistry to biology, the hypothesis of self-assembling droplets, the 'droplet world'.

AA << identify conditions suitable for concurrent peptide generation and self-assembly, and (..) show how a proliferating peptide-based droplet could be created by using synthesised amino acid thioesters as prebiotic monomers. Oligopeptides generated from the monomers spontaneously formed droplets through liquid–liquid phase separation in water. The droplets underwent a steady growth–division cycle by periodic addition of monomers through autocatalytic self-reproduction. Heterogeneous enrichment of RNA and lipids within droplets enabled RNA to protect the droplet from dissolution by lipids. >>
