Published Geomagnetic field protects Earth from electron showers
(via sciencedaily.com) Original source Geophysicists studied the activity of high energy electrons and clarified the unexpected protective role of the geomagnetic field surrounding the Earth.
Published Study finds a surprising new role for a major immune regulator
(via sciencedaily.com) Original source The immune regulatory protein STING has a previously unknown function: acting as an ion channel that allows protons to leak into cells. This discovery makes it the first human immune sensor that can translate danger signals into ion flow.
Published DNA tilts and stretches underlie differences in mutation rates across genomes
(via sciencedaily.com) Original source Researchers have changed the way to look at DNA. They show that DNA is much more than a linear sequence of building blocks; it has a 3D structure that influences the variation of human genome-wide mutation rates meaningfully and consistently, and this is likely conserved among species.
Published Scientists develop gene-editing technology that eliminates EV-A71 RNA viruses
(via sciencedaily.com) Original source A team of scientists has made an important breakthrough in the fight against RNA viruses that cause human diseases and pandemics.
Published Organoids revolutionize research on respiratory infections
(via sciencedaily.com) Original source In a breakthrough for bioengineering, researchers have developed organoids that can model the human respiratory tract. The organoids, called AirGels, allow them to uncover the mechanism by which antibiotic-resistant pathogens like Pseudomonas aeruginosa infect the respiratory tract.
Published How flies develop sight: Scientists use single-cell sequencing to identify cell types in the visual system
(via sciencedaily.com) Original source Researchers have discovered new cell types in the visual system of flies, made possible by their creation of a tool that finds and labels neurons during development. The study combines single-cell sequencing data with a novel algorithm to identify pairs of genes that point to previously unknown cells in the brains of fruit flies.
Published Sun 'umbrella' tethered to asteroid might help mitigate climate change
(via sciencedaily.com) Original source Earth is rapidly warming and scientists are developing a variety of approaches to reduce the effects of climate change. An astronomer has proposed a novel approach -- a solar shield to reduce the amount of sunlight hitting Earth, combined with a tethered, captured asteroid as a counterweight. Engineering studies using this approach could start now to create a workable design that could mitigate climate change within decades.
Published Scientists discover secret of virgin birth, and switch on the ability in female flies
(via sciencedaily.com) Original source Scientists have pinpointed a genetic cause for virgin birth for the first time, and once switched on the ability is passed down through generations of females.
Published Cell biology: How cellular powerhouses call for help when under stress
(via sciencedaily.com) Original source Originally, the powerhouses of higher cells, the mitochondria, were independent organisms. Researchers have investigated to what extent their metabolism has blended with that of their host cells in the course of evolution, using the example of a mitochondrial stress response. They have discovered that mitochondria send two different biochemical signals. These are processed together in the cell and trigger a support mechanism to restore cellular balance (homeostasis).
Published Alternative cellular 'fuels' boost immunity
(via sciencedaily.com) Original source A metabolic by-product that is more prevalent during fasting may supercharge immune cells as they fight infection and disease, reports an early stage study. The findings may pave the way for future personalized dietary recommendations to augment treatments for infection, cancer and other diseases.
Published Bees and wasps use the same architectural solutions to join large hexagons to small hexagons
(via sciencedaily.com) Original source Bees and wasps have converged on the same architectural solutions to nest-building problems, according to new research.
Published Researchers develop 'in vivo' RNA-based gene editing model for blood disorders
(via sciencedaily.com) Original source In a step forward in the development of genetic medicines, researchers have developed a proof-of-concept model for delivering gene editing tools to treat blood disorders, allowing for the modification of diseased blood cells directly within the body. If translated into the clinic, this approach could expand access and reduce the cost of gene therapies for blood disorders, many of which currently require patients receive chemotherapy and a stem cell transplant.
Published Fast electrical signals mapped in plants with new bioelectronic technology
(via sciencedaily.com) Original source What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut. Bioelectronic technology enables advanced research into how plants react to their surroundings, and to stress.
Published Lifespan of aging science's model organism driven by reproductive self-destruction
(via sciencedaily.com) Original source The lifespan of a small roundworm that has been used as a key model organism in aging research is limited by how it self-sacrifices to feed its young, finds a new study.
Published New findings offer potential breakthrough in HIV cure research
(via sciencedaily.com) Original source The results of a novel study has revealed exciting findings in the pursuit of an HIV cure.
Published Discovery of key genetic sequence essential for plant reproduction
(via sciencedaily.com) Original source Researchers have identified a genetic sequence that is essential for plant reproduction. As this region is found in all plant species, it is expected to contribute to future crossbreeding initiatives and help solve the important problem of seed formation defects.
Published Do warmer temperatures make turtles better mothers?
(via sciencedaily.com) Original source Warmer temperatures are known to make more turtle eggs become female hatchlings, but new research shows that those females also have a higher capacity for egg production, even before their sex is set. This finding may explain why many animals besides turtles have temperature-dependent sex determination and why the system persists, despite seeming like a risky strategy. It may also provide a troubling glimpse of what could lie ahead in a warming world.
Published The clue is in the glue -- Nature's secret for holding it together
(via sciencedaily.com) Original source An obscure aquatic plant has helped to explain how plants avoid cracking up under the stresses and strains of growth.
Published Unraveling the connections between the brain and gut
(via sciencedaily.com) Original source Engineers designed a technology to probe connections between the brain and the digestive tract. Using fibers embedded with a variety of sensors, as well as optogenetic stimulation, the researchers could control neural circuits connecting the gut and the brain, in mice.
Published Researchers reveal mechanism of protection against breast and ovarian cancer
(via sciencedaily.com) Original source Researchers have outlined the structure and function of a protein complex which is required to repair damaged DNA and protect against cancer.
