Published Scientists unveil detailed cell maps of the human brain and the nonhuman primate brain
(via sciencedaily.com) Original source A group of international scientists have mapped the genetic, cellular, and structural makeup of the human brain and the nonhuman primate brain. This understanding of brain structure allows for a deeper knowledge of the cellular basis of brain function and dysfunction, helping pave the way for a new generation of precision therapeutics for people with mental disorders and other disorders of the brain.
Published New study unveils stretchable high-resolution user-interactive synesthesia displays for visual--acoustic encryption
(via sciencedaily.com) Original source A research team has succeeded in developing a cutting-edge display using transfer-printing techniques, propelling the field of multifunctional displays into new realms of possibility.
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 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 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 When cells go boom: Study reveals inflammation-causing gene carried by millions
(via sciencedaily.com) Original source Researchers have found that a genetic change that increases the risk of inflammation, through a process described as ‘explosive’ cell death, is carried by up to 3% of the global population.
Published How new plant cell walls change their mechanical properties after cell division
(via sciencedaily.com) Original source Scientists reveal new plant cell walls can have significantly different mechanical properties compared to surrounding parental cell walls, enabling cells to change their local shape and influence the growth of plant organs.
Published Preventing spread of parasitic DNA in our genomes
(via sciencedaily.com) Original source Researchers have identified a new enzyme called PUCH, which plays a key role in preventing the spread of parasitic DNA in our genomes. These findings may reveal new insights into how our bodies detect and fight bacteria and viruses to prevent infections.
Published A hygiene program for chromosomes
(via sciencedaily.com) Original source Researchers identified and characterized a new cellular compartment in vertebrate cells that might be a precursor of today's eucaryotic nucleus. The study reveals that mammalian cells recognize, cluster, sort and keep extrachromosomal DNA -- like transfected plasmid DNA and endogenous circular DNAs originating from telomeres of the chromosome -- away from chromosomal DNA. That suggests that there is a cell autonomous genome defense system.
Published A more effective experimental design for engineering a cell into a new state
(via sciencedaily.com) Original source A new machine-learning approach helps scientists more efficiently identify the optimal intervention to achieve a certain outcome in a complex system, such as genome regulation, requiring far fewer experimental trials than other methods.
Published Researchers studied thousands of fertility attempts hoping to improve IVF
(via sciencedaily.com) Original source By genetically testing nearly one thousand embryos, scientists have provided the most detailed analysis of embryo fate following human in vitro fertilization.
Published Did animal evolution begin with a predatory lifestyle?
(via sciencedaily.com) Original source Surprising findings on the development of sea anemones suggest that a predatory lifestyle molded their evolution and had a significant impact on the origin of their nervous system. The researchers were able to show that the young life stages (larvae) of the small sea anemone Aiptasia actively feed on living prey and are not dependent on algae. To capture its prey, the anemone larvae use specialized stinging cells and a simple neuronal network.
Published A lethal parasite's secret weapon: Infecting non-immune cells
(via sciencedaily.com) Original source The organisms that cause visceral leishmaniasis, a potentially deadly version of the parasitic disease that most often affects the skin to cause disfiguring disease, appear to have a secret weapon, new research suggests: They can infect non-immune cells and persist in those uncommon environments.
Published Fish reveal cause of altered human facial development
(via sciencedaily.com) Original source Some substances in medicines, household items and the environment are known to affect prenatal child development. Researchers tested the effects of five drugs (including caffeine and the blood thinner warfarin) on the growth of zebrafish embryos. They found that all five had the same effect, impairing the migration of bone-forming cells which resulted in the onset of facial malformation. Zebrafish embryos grow quickly, are transparent and develop outside of the parent's body, making them ideal for studying early development. A zebrafish-based system could be used to easily screen for potentially harmful substances, reducing animal testing on mammals and supporting parents-to-be when making choices for themselves and their baby.
Published Vision in the brain: Hardwired for action
(via sciencedaily.com) Original source Brain circuits for vision develop without any kind of input from the retina in zebrafish.
Published New information on the most important early stage of embryonic development
(via sciencedaily.com) Original source A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development.
Published Tiny CRISPR tool could help shred viruses
(via sciencedaily.com) Original source Scientists mapped out the three-dimensional structure of one of the smallest known CRISPR-Cas13 systems then used that knowledge to modify its structure and improve its accuracy.
Published How the heart starts beating
(via sciencedaily.com) Original source Researchers discover that heart cells in developing zebrafish start beating suddenly and all at once
Published Researchers discover disease-causing stem cells in lungs of cystic fibrosis patients
(via sciencedaily.com) Original source Experts in cloning and stem cell science are reporting that five lung stem cell variants dominate the lungs of patients with advanced cystic fibrosis, and that these variants drive key aspects of CF pathology including inflammation, fibrosis and mucin secretion.
