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 Why computer security advice is more confusing than it should be
(via sciencedaily.com) If you find the computer security guidelines you get at work confusing and not very useful, you're not alone. A new study highlights a key problem with how these guidelines are created, and outlines simple steps that would improve them -- and probably make your computer safer.
Published Solving rare disease mysteries ... and protecting privacy
(via sciencedaily.com) Researchers have demonstrated a new way of linking personal records and protecting privacy. The first application is in identifying cases of rare genetic disorders. There are many other potential applications across society.
Published Stressed for a bit? Then don't click it, cybersecurity experts advise
(via sciencedaily.com) Original source Workers feeling a specific form of stress are more likely than others to become the victims of a phishing attack, according to a new study.
Published Evaluating cybersecurity methods
(via sciencedaily.com) Original source Researchers created a generic framework that enables an engineer or scientist to evaluate the effectiveness of defense schemes that seek to limit a hacker's ability to learn secret information by observing the behavior of a victim computer program.
Published How secure are voice authentication systems really?
(via sciencedaily.com) Original source Computer scientists have discovered a method of attack that can successfully bypass voice authentication security systems with up to a 99% success rate after only six tries.
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.
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 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.
