But Do “Hidden Webs of Information” Really Solve Life’s Mystery?

Cosmologist Paul Davies won an award last year for an attempt that left “more questions than clean-cut answers (Physics World)

Last year, State University of Arizona’s cosmologist Paul Davies won a Best Book award from Physics World for Demon in the Machine: The book’s subtitle is “How hidden webs of information are solving the mystery of life.” But are they? The book deals with established physics concepts (such as the second law of thermodynamics), but also delves into Davies’ thoughts on topics such as the emergence of human consciousness (while making sure the reader is aware of what is speculation). Readers, though, are likely to be left with more questions than clean-cut answers about the laws of nature. “Just in the last 10 years or so, I suppose, I’ve begun to see a confluence of different subjects. Partly, this is…

Why Search for Extraterrestrial Life? Why Not Make It Ourselves?

A NASA astrobiologist’s bold suggestion is likely to spark debate

Recently, we have been looking at the question of why we don’t see aliens, with as many as 75 hypotheses offered. But one astrobiologist has a bold suggestion: Why not just seed life on various suitable exoplanets, once we have the means to do it? We need not search for extraterrestrial life if we can learn how to create it ourselves. There are a lot of reasons to think very carefully about doing something like that, as Betül Kaçar (pictured), director of the NASA Astrobiology Consortium MUSE, acknowledges: Rather than regarding the overwhelming majority of planets and moons as failures unworthy of further study, we should instead recognise them for what they are: they’re not empty. In fact, a very…

Has a Computer Algorithm Discovered the Secret of Life?

In the past, a curious pattern wouldn’t have been visible due to the lack of computing resources

Artificial intelligence has enabled a remarkable level of automation of chemistry, with great benefits to us all. Once upon a time there was a multivolume Beilstein’s Handbook of Organic Chemistry, but it is now an online database. Biochemist Fazale Rana (pictured) tells us that, because so much has been discovered about the chemistry of the world we live in, “Learning to master Beilstein’s Handbook is no easy task. In fact, there are textbooks devoted to teaching chemists how to use this massive database effectively.” So putting Beilstein online doesn’t make it a walk in the park but does make it computable. And some have started computing around the origin of life. Origin of life studies have been hampered by the…

Elon Musk Tweet Shows Why Many Doubt Origin of Life Studies

Musk was talking about the origin of machines, not life, but the principle is, perhaps surprisingly, the same
Creating a machine that manufactures or a cell that reproduces is much harder than creating a prototype of either. It’s a search for a search. Read More ›
