THE SLENDER REMAINDER. “More is unknown than is known. We know how much dark energy there is because we know how it affects the universe's expansion. Other than that, it is a complete mystery. But it is an important mystery. It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe.” This is our reality. https://lnkd.in/dZz7Cr7 View in LinkedIn

FRAGMENT FROM NATURE for this and next weekend deals with cone shell patterning. For me, it is a testament to human curiosity that adults can spend lifetimes studying peacock feathers, beetle casings, the patterning of shells, or equally seemingly unimportant things; the reality is that these offer wonderful insights into things like photonic crystals, and the mathematics of chaos, and so much more.

THE PROTEIN UNIVERSE. “It is increasingly accepted that protein evolution has occurred by shuffling of DNA sequences. If nature explored all the possible sequences for a protein of 100 residues, 2(100) proteins would have been produced. It has been calculated that if only 1 μg of each protein was synthesised, the required starting materials would have a mass (1.27 × 10(124) g) greater than that of the earth (5.98 × 10(27) g).” https://lnkd.in/d5kyh6v View in LinkedIn
