Researchers explored the evolution of metal-binding proteins across billions of years.
Addressing one of the most profoundly unanswered questions in biology, a Rutgers-led team has discovered the structures of proteins that may be responsible for the origins of life in the primordial soup of ancient Earth.
The study appears in the journal Science Advances.
Is artificial superintelligence (ASI) imminent? Adam Ford will assess the evidence and ethical importance of artificial intelligence; its opportunities and risks. Drawing on the history of progress in AI and how today it surpasses peak human capability in some domains, he will present forecasts about further progress.
“Progress in AI will likely be explosive; even more significant than both the agricultural and industrial revolutions” — Adam will explore the notion of intelligence and what aspects are missing in AI now and how ‘understanding’ arises in biological intelligence and how it could be realised in AI over the next decade or two. He will conclude with takes on ideal AI outcomes and some recommendations for increasing the likelihood of achieving them.
BIO: Adam Ford (Masters of IT at RMIT) is an IEET Affiliate Scholar, a futurologist and works as a data/information architect, a data analyst and data engineer. He co-organised a variety of conferences in Australia, USA and China. Adam also convenes the global effort of ‘Future Day’ seeking to ritualize focus on the future to a specific day. He is a grass roots journalist, having interviewed many experts on the future, and is currently working on a documentary project focusing on preparing for the future of artificial intelligence.
Research conducted at the University of Campinas in Brazil was driven by observations of fluctuations in autoluminescence caused by seed germination in cycles regulated by gravitational tides.
The rhythms of activity in all biological organisms, both plants and animals, are closely linked to the gravitational tides created by the orbital mechanics of the Sun-Earth-Moon system. This truth has been somewhat neglected by scientific research but is foregrounded in a study by Cristiano de Mello Gallep at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, and Daniel Robert at the University of Bristol in the United Kingdom. An article on the study is published in the Journal of Experimental Botany.
“All matter on Earth, both live and inert, experiences the effects of the gravitational forces of the Sun and Moon expressed in the form of tides. The periodic oscillations exhibit two daily cycles and are modulated monthly and annually by the motions of these two celestial bodies. All organisms on the planet have evolved in this context. What we sought to show in the article is that gravitational tides are a perceptible and potent force that has always shaped the rhythmic activities of these organisms,” Gallep told Agência FAPESP.

The study is both an extensive review of the literature and a meta-analysis of the data from three previously published cases in which gravitational causality was not fully explored: The swimming activity of isopods, small shell-less crustaceans whose appearance on Earth dates from at least 300 million years ago; reproductive effort in coral; and growth modulation in sunflower seedlings inferred from autoluminescence. In the latter case, the researchers analyzed results of their own investigations as well as data from the literature.

The transmission electron microscope (TEM) can image molecular structures at the atomic scale by using electrons instead of light, and has revolutionized materials science and structural biology. The past decade has seen a lot of interest in combining electron microscopy with optical excitations, trying, for example, to control and manipulate the electron beam by light. But a major challenge has been the rather weak interaction of propagating electrons with photons.
In a new study, researchers have successfully demonstrated extremely efficient electron beam modulation using integrated photonic microresonators. The study was led by Professor Tobias J. Kippenberg at EPFL and by Professor Claus Ropers at the Max Planck Institute for Biophysical Chemistry and the University of Göttingen, and is published in Nature.
The two laboratories formed an unconventional collaboration, joining the usually unconnected fields of electron microscopy and integrated photonics. Photonic integrated circuits can guide light on a chip with ultra-low low losses, and enhance optical fields using micro-ring resonators. In the experiments conducted by Ropers’ group, an electron beam was steered through the optical near field of a photonic circuit, to allow the electrons to interact with the enhanced light. The researchers then probed the interaction by measuring the energy of electrons that had absorbed or emitted tens to hundreds of photon energies. The photonic chips were engineered by Kippenberg’s group, built in such a way that the speed of light in the micro-ring resonators exactly matched the speed of the electrons, drastically increasing the electron-photon interaction.
At this point, Scott-Morgan is almost completely “locked-in,” unable to move except for his eyes and a few facial muscles. His sense of smell and taste are gone, and he can’t breathe on his own, but his brilliant mind is fully intact.
Scott-Morgan now relies on a synthetic version of his biological voice and has had his face scanned to produce a 3D animated avatar, which he wears on a screen on his chest when speaking publicly. After a series of operations to extend his life, including a total laryngectomy, he uses technologies like GPT-2, OpenAI’s generative deep-learning model for text, pushing the boundaries of what it means to be human.
Been saying this for years!
A summary of decades of research on a rather ‘out-there’ idea involving viruses from space raises questions on just how scientific we can be when it comes to speculating on the history of life on Earth.
It’s easy to throw around words like crackpot, rogue, and maverick in describing the scientific fringe, but then papers like this one, from 2018, come along and leave us blinking owlishly, unsure of where to even begin.
A total of 33 names were listed as authors on this review, which was published by Progress in Biophysics and Molecular Biology back in August 2018. The journal is peer reviewed and fairly well cited. So it’s not exactly small, or a niche pay-for-publish source.
How does our biology give rise to the experience of consciousness?
Anil’s new book “Being You” is available now: https://geni.us/anil.
Watch the Q&A: https://youtu.be/JZS39CaODTs.
Anil Seth argues, using innovative combinations of theory and experiment, that our brains are prediction machines inventing our world and correcting our mistakes by the microsecond. Anil’s new perspective on consciousness has shed light on the nature of the self, free will, the intimate relationship between being alive and being aware — and the possibility of conscious machines.
Anil Seth is Professor of Cognitive and Computational Neuroscience at the University of Sussex, where he is also Co-Director of the Sackler Centre for Consciousness Science. He is also a Wellcome Trust Engagement Fellow, Co-Director of the Canadian Institute for Advanced Research (CIFAR) Program on Brain, Mind, and Consciousness, and Co-Director of the Leverhulme Doctoral Scholarship Programme: From Sensation and Perception to Awareness.
