Neil deGrasse Tyson
“Imagine a life-form whose brainpower is to ours as ours is to a chimpanzee’s. To such a species, our highest mental achievements would be trivial. Their toddlers, instead of learning their ABCs on Sesame Street, would learn multivariable calculus on Boolean Boulevard. Our most complex theorems, our deepest philosophies, the cherished works of our most creative artists, would be projects their schoolkids bring home for Mom and Dad to display on the refrigerator door.”
Neil deGrasse Tyson, Space Chronicles: Facing the Ultimate Frontier

Jonah Lehrer
“Science has discovered that, like any work of literature, the human genome is a text in need of commentary, for what Eliot said of poetry is also true of DNA: 'all meanings depend on the key of interpretation.' What makes us human, and what makes each of us his or her own human, is not simply the genes that we have buried into our base pairs, but how our cells, in dialogue with our environment, feed back to our DNA, changing the way we read ourselves. Life is a dialectic.”
Jonah Lehrer, Proust Was a Neuroscientist

Rebecca Skloot
“They also knew that there was a string of DNA at the end of each chromosome called a telomere, which shortened a tiny bit each time a cell divided, like time ticking off a clock. As normal cells go through life, their telomeres shorten with each division until they’re almost gone. Then they stop dividing and begin to die. This process correlates with the age of a person: the older we are, the shorter our telomeres, and the fewer times our cells have left to divide before they die. By the early nineties, a scientist at Yale had used HeLa to discover that human cancer cells contain an enzyme called telomerase that rebuilds their telomeres. The presence of telomerase meant cells could keep regenerating their telomeres indefinitely. This explained the mechanics of HeLa’s immortality: telomerase constantly rewound the ticking clock at the end of Henrietta’s chromosomes so they never grew old and never died.”
Rebecca Skloot, The Immortal Life of Henrietta Lacks

James D. Watson
“At lunch Francis winged into the Eagle to tell everyone within hearing distance that we had found the secret of life.”
James D. Watson

Sam Kean
“Lithium regulates the proteins that control the body’s inner clock. This clock runs, oddly, on DNA, inside special neurons deep in the brain. Special proteins attach to people’s DNA each morning, and after a fixed time they degrade and fall off. Sunlight resets the proteins over and over, so they hold on much longer. In fact, the proteins fall off only after darkness falls—at which point the brain should “noticeâ€� the bare DNA and stop producing stimulants. This process goes awry in manic-depressives because the proteins, despite the lack of sunlight, remain bound fast to their DNA. Their brains don’t realize they should stop revving. Lithium helps cleave the proteins from DNA so people can wind down. Notice that sunlight still trumps lithium during the day and resets the proteins; it’s only when the sunlight goes away at night that lithium helps DNA shake free. Far from being sunshine in a pill, then, lithium acts as “anti-sunlight.â€� Neurologically, it undoes sunlight and thereby compresses the circadian clock back to twenty-four hours—preventing both the mania bubble from forming and the Black Tuesday crash into depression.”

Jacques Monod
“The fundamental biological variant is DNA. That is why Mendel's definition of the gene as the unvarying bearer of hereditary traits, its chemical identification by Avery (confirmed by Hershey), and the elucidation by Watson and Crick of the structural basis of its replicative invariance, are without any doubt the most important discoveries ever made in biology. To this must be added the theory of natural selection, whose certainty and full significance were established only by those later theories.”
Jacques Monod, Chance and Necessity: An Essay on the Natural Philosophy of Modern Biology

Neil Shubin
“Imagine a house coming together spontaneously from all the information contained in the bricks: that is how animal bodies are made.”
Neil Shubin

Maurice Wilkins
“It is essential for genetic material to be able to make exact copies of itself; otherwise growth would produce disorder, life could not originate, and favourable forms would not be perpetuated by natural selection.”
Maurice Wilkins

Linus Pauling
“I think that the formation of [DNA's] structure by Watson and Crick may turn out to be the greatest developments in the field of molecular genetics in recent years.”
Linus Pauling

“To get leaders to become stakeholders in ministry and to understand the DNA of your church, you must invest in them, equip them, and raise the bar of accountability.”
Sue Mallory, The Equipping Church

Frederick Sanger
“A DNA sequence for the genome of bacteriophage ΦX174 of approximately 5,375 nucleotides has been determined using the rapid and simple 'plus and minus' method. The sequence identifies many of the features responsible for the production of the proteins of the nine known genes of the organism, including initiation and termination sites for the proteins and RNAs. Two pairs of genes are coded by the same region of DNA using different reading frames.”
Frederick Sanger

Dean Cavanagh
“Would a DNA test for love take a sample from the heart or the mind?”

James Morcan
“Because of their sublime genes, the orphans were all incredible specimens and often referred to by their creator, Doctor Pedemont, and by Naylor, Kentbridge and the rest of their Omega masters, as post-humans. Their DNA was different to anyone else’s and by their teens they were superior in many ways to the rest of the population, being smarter, faster, stronger and more adaptable.”
James Morcan, The Ninth Orphan

Allan Pease
“Most people have difficulty thinking of themselves as just another animal. They refuse to face the fact that 96% of what can be found in their bodies can also be found inside a pig or a horse or that our DNA is 97. 5% identical to that of a gorilla and 98. 4% to that of a chimpanzee. The only thing that makes us different from other animals is our ability to think and make forward plans.”

“O que é se entrega ao que está prestes a ser: tudo, tudo verte em uma arte fractal: pequeninos sonhos como as bases do meu dna.”
Filipe Russo, Caro Jovem Adulto

Lewis Thomas
“All of today's DNA, strung through all the cells of the earth, is simply an extension and elaboration of [the] first molecule.”
Lewis Thomas, The Medusa and the Snail: More Notes of a Biology Watcher

Sam Kean
“So while Pauling struggled with his model, Watson and Crick turned theirs inside out, so the negative phosphorus ions wouldn’t touch. This gave them a sort of twisted ladder—the famed double helix.”
Sam Kean, The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements

B.C. Chase
“Now the leatherback turtle overcame the heat issue via a simple, but evolutionarily impossible solution; it is the only reptile that possesses fatty insulation known as brown adipose tissue, and the only reptile that regulates a high body temperature. This brown adipose tissue is the expression of the UCP1 gene, and, aside from the leatherbacks, is found only in mammals, amphibians, and fishes. Not one other reptile has UCP1.”
B.C.CHASE

B.C. Chase
“The platypus, as it turns out, derives its DNA from a menagerie of creatures. When its genome was fully decoded, it was found only to be 80% mammalian, and had genes found previously only in reptilian, bird, amphibian, and fish DNA.”
B.C.CHASE
