Published The medicine of the future could be artificial life forms
(via sciencedaily.com) Original source Imagine a life form that doesn't resemble any of the organisms found on the tree of life. One that has its own unique control system, and that a doctor would want to send into your body. It sounds like a science fiction movie, but according to nanoscientists, it can—and should—happen in the future.
Published Physicists find evidence for magnetically bound excitons
(via sciencedaily.com) Original source Physicists have experimentally detected how so-called Hubbard excitons form in real-time.
Published New open-source method to improve decoding of single-cell data
(via sciencedaily.com) Original source Researchers have developed a new open-source computational method, dubbed Spectra, which improves the analysis of single-cell transcriptomic data. By guiding data analysis in a unique way, Spectra can offer new insights into the complex interplay between cells — like the interactions between cancer cells and immune cells, which are critical to improving immunotherapy treatments.
Published New research may make future design of nanotechnology safer with fewer side effects
(via sciencedaily.com) Original source A new study may offer a strategy that mitigates negative side effects associated with intravenous injection of nanoparticles commonly used in medicine.
Published Two-dimensional compounds can capture carbon from the air
(via sciencedaily.com) Original source Some of the thinnest materials known to humankind -- MXene and MBene compounds -- may provide solutions to scientists in their quest to curb the effects of global warming. These substances are only a few atoms thick, making them two-dimensional. Because of their large surface area, the materials have the potential to absorb carbon dioxide molecules from the atmosphere, which could help reduce the harmful effects of climate change by safely sequestering carbon dioxide, according to a review study.
Published New 'Assembly Theory' unifies physics and biology to explain evolution and complexity
(via sciencedaily.com) Original source An international team of researchers has developed a new theoretical framework that bridges physics and biology to provide a unified approach for understanding how complexity and evolution emerge in nature. This new work on 'Assembly Theory' represents a major advance in our fundamental comprehension of biological evolution and how it is governed by the physical laws of the universe.
Published Could future AI crave a favorite food?
(via sciencedaily.com) Original source Can artificial intelligence (AI) get hungry? Develop a taste for certain foods? Not yet, but a team of researchers is developing a novel electronic tongue that mimics how taste influences what we eat based on both needs and wants, providing a possible blueprint for AI that processes information more like a human being.
Published These robots helped explain how insects evolved two distinct strategies for flight
(via sciencedaily.com) Original source Robots helped achieve a major breakthrough in our understanding of how insect flight evolved. The study is a result of a six-year long collaboration between roboticists and biophysicists.
Published Graphene oxide reduces the toxicity of Alzheimer's proteins
(via sciencedaily.com) Original source A probable early driver of Alzheimer's disease is the accumulation of molecules called amyloid peptides. These cause cell death, and are commonly found in the brains of Alzheimer’s patients. Researchers have now shown that yeast cells that accumulate these misfolded amyloid peptides can recover after being treated with graphene oxide nanoflakes.
Published Human disease simulator lets scientists choose their own adventure
(via sciencedaily.com) Original source Scientists have developed a device smaller than a toddler's shoebox -- called Lattice --that can simulate any human disease in up to eight organs (cell cultures from a human organ) or test new drugs without ever entering -- or harming -- the body. It is a major advancement from current in vitro systems, which can only study two cell cultures simultaneously.
Published Electronic sensor the size of a single molecule a potential game-changer
(via sciencedaily.com) Original source Researchers have developed a molecular-sized, more efficient version of a widely used electronic sensor, in a breakthrough that could bring widespread benefits.
Published Bioengineering breakthrough increases DNA detection sensitivity by 100 times
(via sciencedaily.com) Original source Researchers have pushed forward the boundaries of biomedical engineering one hundredfold with a new method for DNA detection with unprecedented sensitivity.
Published Wearable sensor to monitor 'last line of defense' antibiotic
(via sciencedaily.com) Original source Researchers have combined earlier work on painless microneedles with nanoscale sensors to create a wearable sensor patch capable of continuously monitoring the levels of a ‘last line of defense’ antibiotic.
Published Metal-loving microbes could replace chemical processing of rare earths
(via sciencedaily.com) Original source Scientists have characterized the genome of a metal-loving bacteria with an affinity for rare earth elements. The research paves the way towards replacing the harsh chemical processing of these elements with a benign practice called biosorption.
Published Small but mighty new gene editor
(via sciencedaily.com) Original source A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders. The tool is an enzyme, AsCas12f, which has been modified to offer the same effectiveness but at one-third the size of the Cas9 enzyme commonly used for gene editing. The compact size means that more of it can be packed into carrier viruses and delivered into living cells, making it more efficient.
Published Making elbow room: Giant molecular rotors operate in solid crystal
(via sciencedaily.com) Original source Concave, umbrella-like metal complexes provide space to enable the largest molecular rotor operational in the solid-state.
Published Intense lasers shine new light on the electron dynamics of liquids
(via sciencedaily.com) Original source The behavior of electrons in liquids is crucial to understanding many chemical processes that occur in our world. Using advanced lasers that operate at the attosecond, a team of international researchers has revealed further insights into how electrons behave in liquids.
Published A deep look into the progression of Parkinson's Disease
(via sciencedaily.com) Original source Scientists have used cutting-edge imaging techniques to shed light on the progression of Parkinson's disease by studying how the main culprit, the protein alpha-synuclein, disrupts cellular metabolism.
Published An advance in cryo-EM could be a significant boon for research on potential cancer therapies
(via sciencedaily.com) Original source A technology called cryo-electron microscopy enables scientists to see the atomic structure of biological molecules in high resolution. But to date, it has been ineffective for imaging small molecules. A team of biochemists devised a solution that makes it possible to hold small protein molecules in place while they're being imaged, which will enable cryo-EM to produce much clearer images of such molecules. The advance is significant because small and medium-sized protein molecules are an area of focus in research on potential new drugs for cancer and other diseases.
Published Researchers dynamically tune friction in graphene
(via sciencedaily.com) Original source The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers.
