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 Lasering lava to forecast volcanic eruptions
(via sciencedaily.com) Original source Researchers have optimized a new technique to help forecast how volcanoes will behave, which could save lives and property around the world.
Published Research reveals sources of CO2 from Aleutian-Alaska Arc volcanoes
(via sciencedaily.com) Original source Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than traveling deep into Earth's mantle.
Published Climate change will increase impacts of volcanic eruptions
(via sciencedaily.com) Original source Volcanic disasters have been studied since Pompeii was buried in 79 A.D., leading the public to believe that scientists already know why, where, when and how long volcanoes will erupt. But a volcanologist said these fundamental questions remain a mystery.
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 Effect of volcanic eruptions significantly underestimated in climate projections
(via sciencedaily.com) Original source Researchers have found that the cooling effect that volcanic eruptions have on Earth's surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections.
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.
Published Scientists discover new embryonic cell type that self-destructs to protect the developing embryo
(via sciencedaily.com) Original source Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos.
Published The speed of life: A zoo of cells to study developmental time
(via sciencedaily.com) Original source Researchers have used an unprecedented stem cell zoo to compare six different mammalian species and their developmental time.
Published A Tongan volcano plume produced the most intense lightning rates ever detected
(via sciencedaily.com) Original source New research showed that the plume emitted by the Hunga Volcano eruption in 2022 created the highest lightning flash rates ever recorded on Earth, more than any storm ever documented.
Published A new tool to study complex genome interactions
(via sciencedaily.com) Original source Genome Architecture Mapping captures complex, multi-way interactions in the genome. This is different than the workhorse technique of 3D genomics, which sees mostly two-way contacts, finds a new study.
Published Tethering of shattered chromosomal fragments paves way for new cancer therapies
(via sciencedaily.com) Original source Scientists discover shattered chromosomal fragments are tethered together during cell division before being rearranged; destroying the tether may help prevent cancerous mutations.
Published Close up on aging reveals how different cell types in the body age at different pace
(via sciencedaily.com) Original source A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.
Published Scientists investigate the evolution of animal developmental mechanisms, show how some of Earth's earliest animals evolved
(via sciencedaily.com) Original source Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research shows that appearances can be deceiving, and that a common genetic toolkit can be deployed in different ways to drive embryological development to produce very different adult body plans. It is well established that sea anemones, corals, and their jellyfish relatives shared a common ancestor with humans that plied the Earth's ancient oceans over 600 million years ago. A new study from the Gibson Lab, published in Current Biology on June 13, 2023, illuminates the genetic basis for body plan development in the starlet sea anemone, Nematostella vectensis. This new knowledge paints a vivid picture of how some of the earliest animals on earth progressed from egg to embryo to adult.
Published Which came first: The reptile or the egg?
(via sciencedaily.com) Original source The earliest reptiles, birds and mammals may have borne live young, researchers have revealed.
Published Campi Flegrei volcano edges closer to possible eruption
(via sciencedaily.com) Original source The new study used a model of volcano fracturing to interpret patterns of earthquakes and ground uplift, and concluded that parts of the volcano had been stretched nearly to breaking point.
Published New research identifies cells linking chronic psychological stress to inflammatory bowel disease
(via sciencedaily.com) Original source For the first time, cells involved with the communication between stress responses in the brain and inflammation in the gastrointestinal (GI) tract have been identified in animal models. Glial cells, which support neurons, communicate stress signals from the central nervous system (CNS) to the semi-autonomous nervous system within the gastrointestinal (GI) tract, called the enteric nervous system (ENS). These psychological stress signals can cause inflammation and exacerbate symptoms of inflammatory bowel disease (IBD).
