Planetary Intelligence

Charles Lineweaver

Can the idea of intelligence as a collective property be extended to a planetary scale? A recent paper explores possible trajectories for the long-term evolution of inhabited planets, including our own.

Long Thoughts

Rufin VanRullen

Were consciousness to be updated only twice per second, as some claim, decisions would take place during an unconscious processing stage, meaning our free will might just be an illusion.

A Lonely Universe

Charles Lineweaver

Is anybody out there? Likely not. The occurrence of intelligent life on Earth is moot when modeling for its likelihood on other planets.

Much Ado About Nothing

James Tour

Recent research by Jiménez, Gibard, and Krishnamurthy is further evidence, if any were needed, that eminent synthetic chemists—and scientists in general—remain clueless about life’s origins.

Metallic Hydrogen

Isaac Silvera & Ranga Dias

For over eighty years, scientists have been trying to produce metallic hydrogen. In that process, diamond anvils must withstand pressures greater than those at the center of the earth—no mean feat.

Reconstructing Ancestral Proteins

Chase Nelson

As the aphorism suggests, the present is the key to the past. In the study of evolution, ancestral proteins can be inferred from modern ones. But recent work challenges just how much should be inferred.

Complexity Far from Equilibrium

Michael Engel

Life is a sophisticated example of dynamic self-assembly, which occurs far from equilibrium. Can researchers harness this phenomenon to purposefully create and control more diversely complex behavior?

The Origin of Novel Genes

Richard Buggs

A series of studies finds that novel genes do not accumulate with Darwinian gradualism in the phylogeny, but can be gained through radical overhauls. How this might be accomplished is a mystery.

The Internal Language of Proteins

Zachary Ardern

Could proteins share a common language across the major branches of life? A new paper investigates the arrangements of protein domains, considering them as a kind of ordered grammar.
