Georgia Tech biochemist Loren Williams was recently named co-leader of NASA’s new consortium to tackle origin of life: Did life on Earth originate in Darwin’s warm little pond, on a sunbaked shore, or where hot waters vent into the deep ocean? And could a similar emergence have played out on other bodies in our solar system or planets far beyond? These questions lie at the center of research in NASA’s new Prebiotic Chemistry and Early Earth Environments (PCE3) Consortium. One of five cross-divisional research coordination networks with the NASA Astrobiology Program, PCE3 aims to identify planetary conditions that might give rise to life’s chemistry. One goal of PCE3 is to guide future NASA missions targeting discovery of habitable worlds. Aaron Read More ›

The mechanome, “the body of knowledge about mechanical forces at work in the molecular, cellular, anatomical, and physiological processes that contribute to the architecture of living structures and their physical properties,” became more prominent this year in discussions of biology (though one story on the physics of biology late last year garnered 354 comments). For so long, the genome ran away with all the interest and publicity but maybe that’s changing. At her blog, science writer Suzan Mazur talks about the way that mechanobiology is becoming mainstream: “When I say mechanobiology is all the rage, I’m not simply referring to lab research and scientific conferences on the subject, although they are, of course, central. But also to: (1) mechanobiology university Read More ›

At her blog, Oscillations, Suzan Mazur reports on the lecture series Simons Center for Geometry and Physics has been hosting at Stony Brook University, on Nonequilibrium Physics in Biology: Among the more interesting presenters is Kim Sneppen, a professor of complex systems and biophysics at Neils Bohr Institute in Copenhagen, who addresses the diversity of shapes in the biological world. Sneppen says, “We are basically all doughnuts” and describes how we go from a sphere to a torus in his talk titled: “Theoretical Tool Bridging Cell Polarities with Development of Morphologies.” Suzan Mazur, “Kim Sneppen, Simons Center Talk: “We are basically all doughnuts”” at Oscillations Mazur discusses his approach to embryology and along the way mentions Stuart Pivar, an early Read More ›

From Suzan Mazur, author of The Origin of Life Circus and The Paradigm Shifters: Overthrowing ‘the Hegemony of the Culture of Darwin’, links to some vintage films of origin of life conferences funded by chemist Harry Lonsdale (1932–2014): Before he died Harry Lonsdale sent me a package with his book on politics—Running: Politics, Power, and the Press—and a flashdrive of his 2013 meeting with the origin of life research teams he funded. I assume he wanted me to share. Following in four parts is Lonsdale’s 2013 origin of life video conference with John Sutherland, Matt Powner, Dave Deamer, et al. The original link to the meeting seems to have disappeared from the Internet. Of particular interest—John Sutherland’s presentation and Nick Read More ›

At her blog, Oscillations, Suzan Mazur reflects on what we have learned to date (it is only 5% excavated). One of the issues is whether there was any religion at Çatalhöyük: Suzan Mazur: I’m asking this because Templeton has come under fire for putting its fingers all over science from the investigation of the origin and evolution of life to space science. It’s perceived that the foundation is compromising the work of scientists and retarding science. Maurice Bloch, one of your own Çatal book authors has said pursuing a religion angle at Çatal is “a misleading wild goose chase” because humans only thought up religion 5,000 years ago at the earliest. Bloch says humans largely live in their reflective imagination, Read More ›

At one time, the cell membrane was thought of as something like a building block made of lipids. Suzan Mazur interviews Swedish physical chemist Tommy Nylander about the study of living cells through neutron scattering (to avoid contamination, the Swedes do the studies without nuclear power or mercury) at Oscillations: Tommy Nylander:I’m very interested in different structures that can occur in living cells. In particular, structures generated by lipids, or fats, if you want. Previously lipids were considered as only a building block with no or very minute function. Merely a support. Suzan Mazur: Cell membranes are made of lipids. Tommy Nylander: Yes. Today it’s realized that lipids can perform various functions that can be very important for cell maintenance Read More ›

Including things you didn’t know about Archaea discoverer, Carl Woese. From a review of The Tangled Tree:A Radical New History of Life by David Quammen (Simon & Schuster, 2018): In The Tangled Tree, celebrated science writer David Quammen tells perhaps the grandest tale in biology: how scientists used gene sequencing to elucidate the evolutionary relationships between living beings. Charles Darwin called it the ‘great Tree of Life’. But as Quammen reveals, at the molecular level, life’s history is more accurately depicted as a network, a tangled web through which organisms have been exchanging genes for more than 3 billion years. This perspective is indeed radical, and he presents the science — and the scientists involved — with patience, candour and Read More ›

With an interesting chapter on carnivorous plants. At Oscillations, Suzan Mazur takes note of the new book by structuralist Antonio Lima de Faria, now an emeritus professor at Lund University, whom she describes as “one of the Osaka Group of ‘structuralists,’ whose other members included Brian Goodwin, Mae-Wan Ho, Peter Saunders et al.” The main theme of Periodic Tables Unifying Living Organisms at the Molecular Level: The Predictive Power of the Law of Periodicity is that “the recurrence of form and function in biology makes possible a periodic table similar to the periodic table of chemical elements (a subject first explored in his 1983 book) and reveals the “law of biological periodicity.” Carnivorous plants have long been an evolutionary puzzle: In the section “Periodicity of Plant Carnivory,” Lima-de-Faria makes Read More ›

From science writer Suzan Mazur, at Oscillations, interviewing Bogdan Dragnea, who studies the physical structure of viruses via spectrosopy: Suzan Mazur: Do you consider viruses live organisms since viruses can recognize their targets, attach, and infect their hosts—most viruses using a tail spike and needle [see following Parent lab image]—and as you’ve noted, they can “drive large-scale phenomena across the entire biosphere”? Bogdan Dragnea: No, I don’t. I will stick with the definition that requires for a living organism to reproduce and produce mechanical work in a thermodynamic cycle. If it could do that, then I would say it’s alive. But the virus cannot do mechanical work as part of a cyclic transformation. That is because they do not have Read More ›
