Much Ado About Nothing
James Tour
[long_description] Rather than leading to any sort of chemical model, recent research by Eddy Jiménez, Clémentine Gibard, and Ramanarayanan Krishnamurthy serves only to underscore that their particular approach is unlikely to yield any clues about how life emerged. It is further evidence, if any were needed, that eminent synthetic chemists—and scientists in general—remain clueless about life’s origins.

Time Out
James Tour
[short_description] Should researchers who study the origins of life take a time-out? James Tour says they should hit pause, in order to assess what they have accomplished, and what more is even possible to accomplish.

The Fourth State of Water
Marc Henry
[short_description] What is water that is not ice, liquid, or vapor? Marc Henry explains the unfolding discovery of water’s elusive fourth state, which could bring a revolution for biology and medicine.

Water and Its Mysteries
Marc Henry
[short_description] There are few things, Marc Henry observes, that modern science does not understand. One is consciousness; the other is water. The behavior of water at supercooled temperatures is a case in point.

An Open Letter to My Colleagues
James Tour
[short_description] According to James Tour, the overwhelming complexity of biological life—the rich variety of saccharides and the complicated structure of the lipid bilayer—is beyond man’s ability to duplicate.

Super-Saturated Chemistry
Marc Henry
[short_description] Is chemistry soluble in physics? Marc Henry says no. Quantum chemistry is a mathematical experiment, not the numerical resolution of a physical equation.

Chiral Induced Spin Selectivity
James Tour
[short_description] Synthetic chemist James Tour reviews an experiment showing chiral induced spin selectivity: K. Michaeli, N. Kantor-Uriel, R. Naaman, and D. Wadleck, “The Electron’s Spin and Molecular Chirality.”

Two Experiments in Abiogenesis
James Tour
[short_description] Two new papers claim to find further support for the RNA World hypothesis and that nucleotide formation and selection may have been robust processes on the prebiotic Earth. James Tour disagrees.

Animadversions of a Synthetic Chemist
James Tour
[short_description] Chemists study molecules. Synthetic chemists make them. What Nature does is anyone’s guess. James Tour constructs nanovehicles and considers the difficulties. What can we say of abiogenesis?
######### Card Article Topic MAIN c #########
The Hydrogen Bond
Marc Henry
[short_description] That chemistry has been explained in terms of quantum theory is now received wisdom. Yet quantum physics is unable to predict or explain the strong association of water molecules in liquid or ice.
