Published Researchers show classical computers can keep up with, and surpass, their quantum counterparts
(via sciencedaily.com) Original source A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers.
Published Technique could improve the sensitivity of quantum sensing devices
(via sciencedaily.com) Original source A new technique can control a larger number of microscopic defects in a diamond. These defects can be used as qubits for quantum sensing applications, and being able to control a greater number of qubits would improve the sensitivity of such devices.
Published Combining materials may support unique superconductivity for quantum computing
(via sciencedaily.com) Original source A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing.
Published New research uncovers biological drivers of heart disease risk
(via sciencedaily.com) Original source Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.
Published Researchers discover key to molecular mystery of how plants respond to changing conditions
(via sciencedaily.com) Original source A team of researchers recently published a pioneering study that answers a central question in biology: how do organisms rally a wide range of cellular processes when they encounter a change -- either internally or in the external environment -- to thrive in good times or survive the bad times? The research, focused on plants, identifies the interactions between four compounds: pectin, receptor proteins FERONIA and LLG1 and the signal RALF peptide.
Published Scientists develop new biocontainment method for industrial organisms
(via sciencedaily.com) Original source Researchers have developed a new biocontainment method for limiting the escape of genetically engineered organisms used in industrial processes.
Published Extra fingers and hearts: Pinpointing changes to our genetic instructions that disrupt development
(via sciencedaily.com) Original source Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and hearts. Such knowledge opens the door to predictions of which enhancer variants underlie disease in order to harness the full potential of our genomes for better human health.
Published Computer-engineered DNA to study cell identities
(via sciencedaily.com) Original source A new computer program allows scientists to design synthetic DNA segments that indicate, in real time, the state of cells. It will be used to screen for anti-cancer or viral infections drugs, or to improve gene and cell-based immunotherapies.
Published Direct view of tantalum oxidation that impedes qubit coherence
(via sciencedaily.com) Original source Scientists have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum -- a superconductor that shows great promise for making the 'qubit' building blocks of a quantum computer -- it can impede the material's ability to retain quantum information. Learning how the oxide forms may offer clues as to why this happens -- and potentially point to ways to prevent quantum coherence loss.
Published Magnesium protects tantalum, a promising material for making qubits
(via sciencedaily.com) Original source Scientists have discovered that adding a layer of magnesium improves the properties of tantalum, a superconducting material that shows great promise for building qubits, the basis of quantum computers. The scientists show that a thin layer of magnesium keeps tantalum from oxidizing, improves its purity, and raises the temperature at which it operates as a superconductor. All three may increase tantalum's ability to hold onto quantum information in qubits.
Published Mechanism discovered that protects tissue after faulty gene expression
(via sciencedaily.com) Original source A study has identified a protein complex that is activated by defects in the spliceosome, the molecular scissors that process genetic information. Future research could lead to new therapeutic approaches to treat diseases caused by faulty splicing.
Published A physical qubit with built-in error correction
(via sciencedaily.com) Original source Researchers have succeeded in generating a logical qubit from a single light pulse that has the inherent capacity to correct errors.
Published The arrangement of bacteria in biofilms affects their sensitivity to antibiotics
(via sciencedaily.com) Original source Many bacteria form an antibiotic-resistant slime. Research detailing that slime's structure could help lead to new treatments.
Published LSH genes associated with defining the shapes of stems, flowers and leaves required for N-fixing root nodules
(via sciencedaily.com) Original source The developmental regulators that confer the identity of N-fixing root nodules belong to a transcription factor family (LSH) more commonly associated with defining the shapes of stems, flowers and leaves.
Published Scientists make breakthrough in quantum materials research
(via sciencedaily.com) Original source Researchers describe the discovery of a new method that transforms everyday materials like glass into materials scientists can use to make quantum computers.
Published Using computers to design proteins allows researchers to make tunable hydrogels that can form both inside and outside of cells
(via sciencedaily.com) Original source New research demonstrates a new class of hydrogels that can form not just outside cells, but also inside of them. These hydrogels exhibited similar mechanical properties both inside and outside of cells, providing researchers with a new tool to group proteins together inside of cells.
Published DNA particles that mimic viruses hold promise as vaccines
(via sciencedaily.com) Original source Using a DNA-based delivery particle, researchers created a vaccine that can induce a strong antibody response against SARS-CoV-2.
Published 'Genomic time machine' reveals secrets of our DNA
(via sciencedaily.com) Original source Researchers reveal a novel method to uncover bits of our genetic blueprint that come from ancient genetic parasites, offering fresh insights into human evolution and health.

(via sciencedaily.com) Original source Researchers have incorporated an innovative ultra-broadband, quantum-entangled light source that generates a relatively wide range of infrared photons with wavelengths between 2 m and 5 m for dramatically downsizing the infrared spectroscopy system and upgrading its sensitivity. It can obtain spectra for various target samples, including hard solids, plastics, and organic solutions. This new technique uses the unique properties of quantum mechanics -- such as superposition and entanglement -- to overcome the limitations of conventional techniques.
