Published Predator-prey defense mechanisms unlock key to marine biofuel production
(via sciencedaily.com) Original source Researchers have unpicked the mechanism behind a marine feeding strategy that could provide a valuable renewable source of biofuel.
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 AI language models could help diagnose schizophrenia
(via sciencedaily.com) Original source Scientists have developed new tools, based on AI language models, that can characterize subtle signatures in the speech of patients diagnosed with schizophrenia.
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 Natural GM crops: Grasses take evolutionary shortcut by borrowing genes from their neighbors
(via sciencedaily.com) Original source Grass may transfer genes from their neighbors in the same way genetically modified crops are made, a new study has revealed.
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 Ruffed grouse population more resilient than expected, genetic study finds
(via sciencedaily.com) Original source Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented.
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 Birders and AI push bird conservation to the next level
(via sciencedaily.com) Original source Big data and artificial intelligence (AI) are being used to model hidden patterns in nature, not just for one bird species, but for entire ecological communities across continents. And the models follow each species’ full annual life cycle, from breeding to fall migration to non-breeding grounds, and back north again during spring migration.
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 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.
Published Ancient technology turns plant-based cheese into 'something we want to eat'
(via sciencedaily.com) Original source To produce plant-based cheeses that feel and taste like dairy cheese, scientists have their sights set on fermentation. In a new research result, scientists demonstrate the potential of fermentation for producing climate-friendly cheeses that people want to eat.
Published Scientists develop 3D printing method that shows promise for repairing brain injuries
(via sciencedaily.com) Original source Researchers have produced an engineered tissue representing a simplified cerebral cortex by 3D printing human stem cells. When implanted into mouse brain slices, the structures became integrated with the host tissue. The technique may ultimately be developed into tailored repairs to treat brain injuries.
Published Insect cyborgs: Towards precision movement
(via sciencedaily.com) Original source Insect cyborgs may sound like something straight out of the movies, but hybrid insect computer robots, as they are scientifically called, could pioneer a new future for robotics. It involves using electrical stimuli to control an insect’s movement. Now, an international research group has conducted a study on the relationship between electrical stimulation in stick insects' leg muscles and the resulting torque (the twisting force that causes the leg to move).
Published Instant evolution: AI designs new robot from scratch in seconds
(via sciencedaily.com) Original source Researchers developed the first AI to date that can intelligently design robots from scratch by compressing billions of years of evolution into mere seconds. It's not only fast but also runs on a lightweight computer and designs wholly novel structures from scratch — without human-labeled, bias-filled datasets.
