MOLECULAR SPECIATION. "We have been able to monitor in real time and at a molecular level the diversification of self-replicating molecules into two distinct sets that compete for two different building blocks (‘food’) and so capture an important aspect of the process by which species may arise." https://lnkd.in/dfhRgv9 View in LinkedIn

SIMPLE DRIVERS. "Instead, the researchers relied only on simple kinds of attachments—molecular binding and unbinding reactions that they designed—and mechanical forces." https://lnkd.in/dF6far5 View in LinkedIn

HIGH FIDELITY CHEMICAL INFORMATION. "Their new research found that it is possible to design a mechanism for copying chemical information very accurately without relying on biological enzymes to assemble and separate sequence copies." https://lnkd.in/dF6far5 View in LinkedIn

CRYSTAL ADAPTATION. "DNA tile crystals can be programmed to process information during growth, allowing them to adapt to their environment. Our findings could even form the basis of novel molecular technologies for making complex self-replicating nanoscale objects." https://lnkd.in/dF6far5 View in LinkedIn

ABANDONED HYPOTHESIS. "He proposed, as well, that such crystals might have been the first chemical self-replicators capable of Darwinian evolution. His theory was controversial at the time, and his ideas have never gained widespread support." https://lnkd.in/dF6far5 View in LinkedIn

CRYSTAL REPLICATION. "The idea that crystals can self-replicate was first presented by organic chemist and molecular biologist Graham Cairns-Smith in 1965." https://lnkd.in/dF6far5 View in LinkedIn

METHODOLOGICAL CONSTRAINTS. "These remarkable discoveries have not had sufficient impact on the field and were largely abandoned because of practical difficulties inherent in manual experiments. While the basic findings were validated in some cases, they failed to be reproduced in others, and the whole line of research became abandoned." http://jeb.biologists.org/content/216/20/3799 View in LinkedIn

RAT NEWS. "No one could argue that rats cannot learn. Within a few months, more than 50 labs, including teams at Berkeley, Harvard, MIT and Yale, conducted transfer experiments. McConnell, after failed attempts using salamanders and mynah birds, also turned to rats. And then things got really interesting." https://lnkd.in/esKEPF7 View in LinkedIn

VINDICATION. "Everything changed when, in late 1965, four independent labs reported successful memory-transfer experiments using rats (and in one case, cross-species transfer between rats and mice). Two of these reports appeared in the high-impact journals Science and Nature." https://lnkd.in/esKEPF7 View in LinkedIn

AFFIRMATION. "Our results, obtained using a highly sensitive, objective, quantitative analysis system, support previous findings of Best and Rubenstein that planarians are capable of acquiring a relatively complex, explicit-like memories of environmental familiarity." http://jeb.biologists.org/content/216/20/3799 View in LinkedIn
