Published Win-win in muscle research: Faster results and fewer laboratory animals thanks to new method
(via sciencedaily.com) Original source To study muscle diseases, scientists rely on the mouse as a model organism. Researchers have now developed a new method that is not only faster and more efficient than conventional ones but also greatly reduces the number of experimental animals needed for studying the function of genes in muscle fibers.
Published Self-correcting quantum computers within reach?
(via sciencedaily.com) Original source Quantum computers promise to reach speeds and efficiencies impossible for even the fastest supercomputers of today. Yet the technology hasn't seen much scale-up and commercialization largely due to its inability to self-correct. Quantum computers, unlike classical ones, cannot correct errors by copying encoded data over and over. Scientists had to find another way. Now, a new paper illustrates a quantum computing platform's potential to solve the longstanding problem known as quantum error correction.
Published Exploring parameter shift for quantum fisher information
(via sciencedaily.com) Original source Scientists have developed a technique called 'Time-dependent Stochastic Parameter Shift' in the realm of quantum computing and quantum machine learning. This breakthrough method revolutionizes the estimation of gradients or derivatives of functions, a crucial step in many computational tasks.
Published Omega-3 discovery moves us closer to 'precision nutrition' for better health
(via sciencedaily.com) Original source Researchers have obtained new insights into how African-American and Hispanic-American people’s genes influence their ability to use Omega-3 and Omega-6 fatty acids for good health. The findings are an important step toward “precision nutrition” – where a diet tailored to exactly what our bodies need can help us live longer, healthier lives.
Published A new way to erase quantum computer errors
(via sciencedaily.com) Original source Researchers have demonstrated a type of quantum eraser. The physicists show that they can pinpoint and correct for mistakes in quantum computing systems known as 'erasure' errors.
Published Newfound mechanism suggests drug combination could starve pancreatic cancer
(via sciencedaily.com) Original source A study found that a new combination of treatments safely decreased growth of pancreatic cancer in mice by preventing cancer cells from scavenging for fuel.
Published Epigenetic regulator MOF drives mitochondrial metabolism
(via sciencedaily.com) Original source Researchers have unveiled a new mechanism for regulating mitochondrial function. The findings reveal the critical role played by the enzymatic activity of the lysine acetyltransferase MOF in maintaining mitochondrial integrity and function through acetylation of mitochondrial electron transport chain component COX17. Cells lacking MOF-mediated COX17 acetylation exhibit dramatic mitochondrial defects and impaired ability to produce energy. Underscoring the clinical relevance of these findings, the team also showed that cells from human patients with a developmental disorder caused by mutations in MOF also exhibited respiratory defects that could be ameliorated by interventions such as acetylation-mimetic COX17 or mitochondrially targeted MOF.
Published How male mosquitoes compensate for having only one X chromosome
(via sciencedaily.com) Researchers have discovered the master regulator responsible for balancing the expression of X chromosome genes between males and females in the malaria mosquito. This discovery helps scientists better understand the evolution of the epigenetic mechanisms responsible for equalizing gene expression between the sexes. The findings may contribute to the development of new ways to prevent the spread of malaria.
Published Twisted science: New quantum ruler to explore exotic matter
(via sciencedaily.com) Original source Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, miniaturized standard for electrical resistance that could calibrate electronic devices directly on the factory floor, eliminating the need to send them to an off-site standards laboratory.
Published New discovery may 'unlock' the future of infectious disease and cancer treatment
(via sciencedaily.com) Original source Researchers have identified a 'guard mechanism' for a protein which attacks microbes in infected cells, opening the possibility of new treatments for Toxoplasma, Chlamydia, Tuberculosis and even cancer.
Published The end of genes: Routine test reveals unique divergence in genetic code
(via sciencedaily.com) Original source Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in the DNA code signalling the end of a gene, suggesting the need for further research to better understand this group of diverse organisms.
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 Proteins roll the dice to determine bee sex
(via sciencedaily.com) Original source To date it has been unclear exactly how the sex of a bee is determined. A research team comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. They describe how this process is similar to a game involving two dice.
Published Machine learning used to probe the building blocks of shapes
(via sciencedaily.com) Original source Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths.
Published Avatars to help tailor glioblastoma therapies
(via sciencedaily.com) Original source Scientists have created a new zebrafish xenograft platform to screen for novel treatments for an aggressive brain tumor called glioblastoma, according to a new study.
Published Honeybees are more selective in their choices for nutrition than previously thought
(via sciencedaily.com) Original source An international research group examined which plants honeybees favor when collecting nectar and pollen. The choices honeybees make have an impact on their health and also on humans, as honeybees pollinate important crop plants.
