Feeding the world uses enormous amounts of land, water, fertilizer, pesticide, and fuel. In a step towards a more sustainable solution, researchers have designed a method to make starches from carbon dioxide more efficiently than plants do (Science 2,021 DOI: 10.1126/science.abh4049).
The new technique, which relies on chemical catalysts and a curated combination of natural and engineered enzymes, converts CO2 to starch 8.5 times as efficiently as corn plants can.
The advance hints at sustainable, efficient factory production of food and industrial chemicals by.
Quantum physics is directly linked to consciousness: Observations not just change what is measured, they create it… Here’s the next episode of my new documentary Consciousness: Evolution of the Mind (2021), Part II: CONSCIOUSNESS & INFORMATION

Reverse-engineering our thinking should be done in terms of networks, modules, algorithms and second-order emergence — meta-algorithms, or groups of modules. Neuronal circuits correlate to “immaterial” cognitive modules, and these cognitive algorithms, when activated, produce meta-algorithmic conscious awareness and phenomenal experience, all in all at least two layers of emergence on top of “physical” neurons.
Reality is fundamentally experiential. Nothing is real for us until perceived. The Conscious Instant Hypothesis denotes that we experience waking reality as a series of perceptual frames. Phenomenal mind springs into existence at increments of conscious instants. A series of such conscious instants constitutes a data stream of consciousness. In a sense, consciousness is really mind-based computing of your experiential branch in this quantum multiverse.
John Archibald Wheeler (1911−2008) was one of the first prominent physicists to propose that reality might not be wholly physical, in some sense, our cosmos must be a “participatory” phenomenon requiring the act of conscious observation — and thus consciousness itself. Wheeler also drew attention to implicit connection between physics and information theory, which was invented in 1948 by mathematician Claude Shannon. Just as physics builds on elementary particles, the quanta, defined by measurement, so does information theory. Its “quantum” is the binary unit, or bit, which is a signal represented by one of two choices: yes or no, plus or minus, zero or one. With his famous “it from bit” concept he unites quantum information theory to consciousness and physics.
While Wheeler emphasized bits at his time, it appears that intrinsically quantum-mechanical forms of information – now known as ‘qubits’ – are even more fundamental. In recent years a rising number of theorists have been exploring whether these curious quanta of information may hold the answer to combining quantum theory and general relativity into a quantum theory of gravity.
If we are to reason for the non-dual picture of the world then quantum physics is directly linked to consciousness. The human brain is a physical organ that transmits and interprets electrochemical signals. Its biochemistry is certainly governed by quantum physical laws, and consciousness — which is clearly related to the functioning of the brain — must therefore be related to the quantum physical processes going on within the brain and in the cosmos at large.
Dr. Jennifer Garrison, PhD (http://garrisonlab.com/) is Assistant Professor, Buck Institute for Research on Aging, Founder & Faculty Director, Global Consortium for Reproductive Longevity & Equality (https://www.buckinstitute.org/gcrle/), Assistant Professor in Residence, Cellular and Molecular Pharmacology, UCSF and Adjunct Assistant Professor of Gerontology, USC Leonard Davis School of Gerontology.
Dr. Garrison’s lab is interested in understanding how neuropeptides (a large class of signaling molecules which are secreted from neurons and transmit messages within the brain and across the nervous system) regulate changes in normal and aging animals as well in understanding how they control behavior at both the cell biological and neural circuit level.
Dr. Garrison received her PhD from the University of California San Francisco in Chemistry and Chemical Biology in the laboratory of Dr. Jack Taunton, where she discovered the molecular target of a natural product and elucidated a novel mechanism by which small molecules can regulate protein biogenesis. As a postdoctoral fellow in Dr. Cori Bargmann’s lab at the Rockefeller University, she showed that the nematode C. elegans produces a neuropeptide that is an evolutionary precursor of the mammalian peptides vasopressin and oxytocin, and mapped a neural circuit by which this molecule, nematocin, modulates mating behavior.
Dr. Garrison was named an Alfred P. Sloan Research Fellow and received a Glenn Foundation Award for Research in Biological Mechanisms of Aging in 2,014 and a Next Generation Leader at the Allen Institute for Brain Science in 2015. Her work is funded by the NIH National Institute of General Medical Sciences, the Glenn Foundation for Medical Research, the Alfred P. Sloan Foundation, and the Larry L. Hillblom Foundation.

The study had been supported by LG Energy Solution’s open innovation, a program that actively supports battery-related research. LGES has been working with researchers around the world to foster related techniques.
Silicon anodes are famous for their energy density, which is 10 times greater than the graphite anodes most often used in today’s commercial lithium ion batteries. On the other hand, silicon anodes are infamous for how they expand and contract as the battery charges and discharges, and for how they degrade with liquid electrolytes. These challenges have kept all-silicon anodes out of commercial lithium ion batteries despite the tantalizing energy density. The new work published in Science provides a promising path forward for all-silicon-anodes, thanks to the right electrolyte.
“With this battery configuration, we are opening a new territory for solid-state batteries using alloy anodes such as silicon,” said Darren H. S. Tan, the lead author on the paper. He recently completed his chemical engineering PhD at the UC San Diego Jacobs School of Engineering and co-founded a startup UNIGRID Battery that has licensed this technology.
See how dormant potential energy explodes in psychedelic swirls when chemicals meet by combining oils, alcohols and inks in Petri dishes. Via the dazzling, colourful patterns that emerge, Gatti draws a line back to the surface of the Sun, where the constant churn of a volatile chemical reaction makes life on Earth possible.
Bacteria may get a bad reputation in general, yet it’s actually generally healthy and serves an important role in many habitats, including human bodies. From supporting life on Earth to being employed in industrial and medicinal processes, bacteria have their figurative fingers in many pots — some varieties of bacteria can even filter tainted water and make it safe for human consumption.
A team of researchers from the Indian Institute of Technology, Banaras Hindu University (IIT-BHU) has found a bacteria that can do just that — Named “microbacterium paraoxydans strain VSVM IIT (BHU)” by the scientists, it can separate toxic hexavalent chromium from water in an effective and eco-friendly manner, according to a research published in the Journal of Environmental Chemical Engineering.
Hexavalent chromium is a heavy metal ion that is used in electroplating, welding, and chromate painting, among other things. It’s said to be responsible for health problems in humans like cancers, kidney and liver malfunctioning, and infertility. When compared to current approaches, the scientists believe that this bacterial strain, which can tolerate high amounts of hexavalent chromium, is particularly successful at eliminating the harmful substance from wastewater.
Past and present nuclear activities (energy, research, weapon tests) have increased the urgency to understand the behavior of radioactive materials in the environment. Nuclear wastes containing actinides (e.g. plutonium, americium, curium, neptunium…) are particularly problematic as they remain radioactive and toxic for thousands of years.
Lawrence Livermore National Laboratory (LLNL) scientists and collaborators proposed a new mechanism by which nuclear waste could spread in the environment.
The new findings, that involve researchers at Penn State and Harvard Medical School, have implications for nuclear waste management and environmental chemistry. The research is published in the Journal of the American Chemical Society.
“This study relates to the fate of nuclear materials in nature, and we stumbled upon a previously unknown mechanism by which certain radioactive elements could spread in the environment,” said LLNL scientist and lead author Gauthier Deblonde. “We show that there are molecules in nature that were not considered before, notably proteins like ‘lanmodulin’ that could have a strong impact on radioelements that are problematic for nuclear waste management, such as americium, curium, etc.”
No other life form on our planet has infiltrated every environment as successfully as the minuscule single cells of bacteria. Amongst their manyroles in life on Earth, it turns out some of these microbes are also experts at purifying precious metals.
An international team of researchers has figured out how one metal-gobbling bacterium, Cupriavidus metallidurans, manages to ingest toxic metallic compounds and still thrive, producing tiny gold nuggets as a side-effect.
Just like many other elements, gold can move through what’s known as a biogeochemical cycle — being dissolved, shifted around, and eventually re-concentrated in Earth’s sediment.
In the seven months NASA estimates it would take to fly humans to Mars, any number of catastrophic failures could occur. That’s why Díaz said in a 2010 interview with Popular Science that “chemical rockets are not going to get us to Mars. It’s just too long a trip.” A conventional rocket must use its entire fuel supply in a single controlled explosion during launch before propelling itself towards Mars. There is no abort procedure, the ship will not be able to change course, and if any failure occurred, mission control would have a 10-minute communications delay, meaning they could find themselves helplessly watching on as the crew slowly dies.
