To enable tissue renewal, human tissues constantly eliminate millions of cells, without jeopardizing tissue integrity, form and connectivity. The mechanisms involved in maintaining this integrity remain unknown. Scientists from the Institut Pasteur and the CNRS today revealed a new process which allows eliminated cells to temporarily protect their neighbors from cell death, thereby maintaining tissue integrity. This protective mechanism is vital, and if disrupted can lead to a temporary loss of connectivity.
Normal brain growth curves for children developed childhood brain disorders, infections and injuries
In the United States, nearly every pediatric doctor's visit begins with three measurements: weight, height and head circumference. Compared to average growth charts of children across the country, established in the 1970s, a child's numbers can confirm typical development or provide a diagnostic baseline to assess deviations from the curve. Yet, the brain, of vital importance to the child's development, is merely hinted at in these measurements.
"Topological defects" are formed when the symmetry of a magnetic material is disrupted. Domain walls (DWs) are a type of topological defect that separates regions of different magnetic orientations. A widely studied phenomenon, the manipulation of these defects has potential applications in high-performance memory storage devices, energy processing devices, and quantum computing.
Recess quality, not just the amount of time spent away from the classroom, plays a major role in whether children experience the full physical, mental and social-emotional benefits of recess, a new study from Oregon State University found.
Scientists at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have found a way to simultaneously increase the strength and ductility of an alloy by introducing tiny precipitates into its matrix and tuning their size and spacing. The precipitates are solids that separate from the metal mixture as the alloy cools. The results, published in the journal Nature, will open new avenues for advancing structural materials.
Batteries are potentially a game-changing technology as we decarbonize our economy, and their benefits are even greater when shared across communities, a University of Otago-led study has found.
Co-author Associate Professor Michael Jack, Director of the Energy Programme in the Department of Physics, says reducing costs are seeing rapid deployment of batteries for household use, mainly for storing solar and wind power for later use, but they could have a variety of uses in a future electricity grid.
Lung cancer has the highest mortality rate of all cancers, and treatment options are extremely limited, especially for patients with oncogenic mutations in the KRAS gene. A great deal of hope was invested in the licensing of immune checkpoint inhibitors, but the reality is that some patients respond very well to this treatment while it is completely ineffective in others.
A new study conducted before COVID-19 busted open the leaky pipeline for women in leadership underscores the bias that men are naturally presumed to have leadership potential and women are not and highlights the increased efforts needed by organizations to address the incorrect stereotype post-pandemic.
A research team at the University of Córdoba has developed and evaluated models for the prediction of solar radiation in nine locations in southern Spain and North Carolina (USA).
Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider than conventional ones, and can detect radio waves emitted by many types of molecules in space at once. This is expected to enable significant progresses in the study of the evolution of the Universe and the mechanisms of star and planet formation.
Coastal wetlands - such as salt marshes - provide even more flood protection than previously thought, reducing the risk to lives and homes in estuaries, a new study has revealed.
The researchers' simulations showed that wetlands that grow in estuaries, such as salt marshes, can reduce water levels by up to 2 metres and provide protection far inland up estuary channels.
This subsequently saved up to $38 (£27) million in avoided flood damage costs per estuary during a large storm thanks to the wetlands' role in preventing storm floods.
Augmented reality (AR) is poised to revolutionise the way people complete essential everyday tasks, yet older adults - who have much to gain from the technology - will be excluded from using it unless more thought goes into designing software that makes sense to them.
Skoltech biologists and their colleagues from Koltzov Institute of Developmental Biology, Russia, and the Chemistry Department of Taras Shevchenko University in Ukraine have discovered fairly unlikely drug candidates for treating liver fibrosis and other pathologies -- among pest control chemicals. In addition, the team looked at modifications of the medication called hymecromone, deeming them promising for anti-fibrotic drugs, too.
Amsterdam, July 8, 2021 - While the literature on the digital divide has widely addressed the digital gender gap, its potential implications for electronic government (e-government) / digital government research and practice have hardly been studied.
Lesbian, gay, and bisexual Veterans from the Vietnam era report PTSD and poorer mental health more often than their heterosexual counterparts, according to an analysis of data from the Vietnam Era Health Retrospective Observational Study (VE-HEROeS).
A greater burden of potentially traumatic events among LGB Veterans, such as childhood physical abuse, adult physical assault, and sexual assault, was associated with the differences.
