Cytoskeletons are essential components of cells that perform a variety of tasks, and artificial cytoskeletons that perform these functions are required for the bottom-up assembly of synthetic cells. Now, a multi-functional cytoskeleton mimic has been engineered from DNA, consisting of confined DNA filaments that are capable of reversible self-assembly and transport of gold nanoparticles and vesicular cargo.
Researching Non-Specific Vaccine Effects For Human Health Benefit — Prof. Dr. Christine Stabell Benn, MD, PhD, DMSc, University Of Southern Denmark
Prof. Dr. Christine Stabell Benn, MD, PhD, DMSc, (https://portal.findresearcher.sdu.dk/en/persons/cbenn), is a physician, a professor of global health at the University of Southern Denmark, and a vaccine researcher with almost thirty years of experience in the field, where the focus of her research is “non-specific vaccine effects”, defined as all those other effects, both positive and negative, that vaccines have on our immune systems and overall health, beyond their very specific ability to protect against a specific infectious disease.
Based on a novel intertwined theoretical and experimental approach, we examined one of the pillars of the Orch OR model, namely the gravity-related collapse model. In this context, we examined the Orch OR calculations using the gravity-related (called Diosi-Penrose, DP, for reasons we explain in the article) theory along with recent experimental constraints on the DP cutoff parameter (R0). We showed that, in this context, the Orch OR based on the DP theory is definitively ruled out for the case of atomic nuclei level of separation, without needing to consider the impact of environmental decoherence; we also showed that the case of partial separation requires the brain to maintain coherent superpositions of tubulin of such mass, duration, and size that vastly exceed any of the coherent superposition states that have been achieved with state-of-the-art optomechanics and macromolecular interference experiments. We conclude that none of the scenarios we discuss (with possible exception to the case of partial separation of tubulins) are plausible.
When our phones and computers run out of power, their glowing screens go dark and they die a sort of digital death. But switch them to low-power mode to conserve energy, and they cut expendable operations to keep basic processes humming along until their batteries can be recharged.
Our energy-intensive brain needs to keep its lights on too. Brain cells depend primarily on steady deliveries of the sugar glucose, which they convert to adenosine triphosphate (ATP) to fuel their information processing. When we’re a little hungry, our brain usually doesn’t change its energy consumption much. But given that humans and other animals have historically faced the threat of long periods of starvation, sometimes seasonally, scientists have wondered whether brains might have their own kind of low-power mode for emergencies.
Now, in a paper published in Neuron in January, neuroscientists in Nathalie Rochefort’s lab at the University of Edinburgh have revealed an energy-saving strategy in the visual systems of mice. They found that when mice were deprived of sufficient food for weeks at a time — long enough for them to lose 15%-20% of their typical healthy weight — neurons in the visual cortex reduced the amount of ATP used at their synapses by a sizable 29%.
Manufacturing with atoms has been the siren’s call for many researchers who believed it was the key that could unlock enormous new potential in how we build things. We could develop products that are perfectly precise, contain zero waste and that are 1000x more energy efficient. The problem has always been the same: How? Until now. Wolkow has taken a leading role in laying a new, stable foundation for the world to begin building on the tiniest of scales. Robert Wolkow is a Professor in the Department of Physics, iCORE Chair of Nanoscale Information and Communications Technology at the University of Alberta and Fellow of the Royal Society of Canada. He is also the Principal Research Officer and Nanoelectronics Program Coordinator at the NRC Nanotechnology Research Centre (NRC-NANO), AITF Industrial Chair in Atom Scale Fabrication and CTO of Quantum Silicon Inc.
An award-winning innovator, Wolkow has had a leading role in discovering, altering and deploying atom scale properties of silicon. His years of fundamental advances have laid a broad foundation for practical applications. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

I talk about my PhD research at MIT in Quantum Artificial Intelligence. I also explain the basic concepts of quantum computers, and why they are superior to conventional computers for specific tasks. Prof. Peter Shor, the inventor of Shor’s algorithm and one of the founding fathers of Quantum Computing, kindly agreed to participate in this video.
