Published New study examines the relationship between the rate of wound healing, the circadian rhythm, and 'hair' on cells
(via sciencedaily.com) Original source Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour basis. Most cells in mammalian bodies have cilia of some sort, which are hair-like structures that perform a variety of functions such as movement for motile cilia and aiding in structure in function for non-motile, or primary, cilia. The primary cilia also act as a sensory organ for the cell, a function which has illuminated the primary cilia's potential role in the healing process and how bodies heal at a different rate according to our circadian rhythm. In this research, the role of the primary cilia, biological clock and wound healing is explored.
Published Large language models validate misinformation
(via sciencedaily.com) Original source In a recent study, researchers systematically tested an early version of ChatGPT's understanding of statements in six categories: facts, conspiracies, controversies, misconceptions, stereotypes, and fiction.
Published Single-celled protists in the guts of animals thrive without the 'powerhouse of the cell'
(via sciencedaily.com) Original source Almost all eukaryotic organisms, from plants and animals to fungi, can't survive without mitochondria -- the 'powerhouses of the cell,' which generate chemical energy using oxygen. However, a new study finds that multiple members of the oxymonads, a group of single-celled protists that live inside the guts of termites and other animals, have evolved to live quite happily without them.
Published Clinicians could be fooled by biased AI, despite explanations
(via sciencedaily.com) Original source A new study finds that clinicians were fooled by biased AI models, even with provided explanations for how the model generated its diagnosis.
Published Artificial intelligence can predict events in people's lives
(via sciencedaily.com) Original source Artificial intelligence can analyze registry data on people's residence, education, income, health and working conditions and, with high accuracy, predict life events.
Published Genetic atlas detailing early stages of zebrafish development
(via sciencedaily.com) Original source Researchers have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the first five days of development, a period in which embryos mature from a single cell into distinct cell types.
Published Can you change a chicken into a frog, a fish or a chameleon?
(via sciencedaily.com) Original source Researchers have developed a theoretical framework that can reproduce and predict the patterns associated with gastrulation in a chicken embryo.
Published How the immune system fights to keep herpes at bay
(via sciencedaily.com) Original source In a study of lab-engineered cells, researchers identify how the immune system neutralizes the herpesvirus. The research maps, for the first time, the maneuvers used by virus and host in the cell nucleus, a poorly understood terrain of host-pathogen interaction. The findings could inform the design of new treatments for herpes and other viruses that replicate in the same way.
Published Enzymes can't tell artificial DNA from the real thing
(via sciencedaily.com) Original source Researchers have come one step closer to unlocking the potential of synthetic DNA, which could help scientists develop never-before-seen proteins in the lab.
Published Interactive screen use reduces sleep time in kids
(via sciencedaily.com) Original source While screen time is generally known to affect sleep, new research suggests that interactive engagement, such as texting friends or playing video games, delays and reduces the time spent asleep to a greater extent than passive screen time, like watching television -- especially for teens.
Published Scientists unveil complete cell map of a whole mammalian brain
(via sciencedaily.com) Original source Researchers have created a complete cell atlas of a whole mammalian brain. This atlas serves as a map for the mouse brain, describing the type, location, and molecular information of more than 32 million cells and providing information on connectivity between these cells.
Published Cells move in groups differently than they do when alone
(via sciencedaily.com) Original source A protein that helps generate the force needed for single cells to move works differently in cells moving in groups, a new study shows.
Published Saving endangered species: New AI method counts manatee clusters in real time
(via sciencedaily.com) Original source Accurately counting manatee aggregations within a region is crucial yet challenging. Harnessing the power of AI, researchers are using a deep learning-based crowd counting approach to automatically count the number of manatees in a designated region, using images captured from CCTV cameras, which are readily available, as input. The pioneering study not only addresses the technical challenges of counting in complex outdoor environments but also offers potential ways to aid endangered species.
Published Mice possess natural gene therapy system
(via sciencedaily.com) Original source A previously mysterious small RNA molecule in mice is found to play a crucial role in gene expression, and may be the first identified member of a new class of regulatory RNAs.
Published A rare enzyme role change with bacterial defense system assembly
(via sciencedaily.com) Original source Scientists have revealed a never-before-seen phenomenon in a protein: Alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria commit suicide.
Published Made-to-order diagnostic tests may be on the horizon
(via sciencedaily.com) Original source Researchers have made a breakthrough in diagnostic technology, inventing a 'lab on a chip' that can be 3D-printed in just 30 minutes. The chip has the potential to make on-the-spot testing widely accessible.
Published Researchers safely integrate fragile 2D materials into devices
(via sciencedaily.com) Original source A new technique integrates 2D materials into devices and systems in a single step, while keeping surfaces and interfaces free from defects. This method could enable devices like those in computer chips to achieve better performance than those made with conventional fabrication techniques.
Published Immersive VR goggles for mice unlock new potential for brain science
(via sciencedaily.com) Original source New miniature virtual reality (VR) goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlies behavior. Compared to current state-of-the-art systems, which simply surround mice with computer or projection screens, the new goggles provide a leap in advancement.
Published World's first logical quantum processor
(via sciencedaily.com) Original source A team has realized a key milestone in the quest for stable, scalable quantum computing. For the first time, the team has created a programmable, logical quantum processor, capable of encoding up to 48 logical qubits, and executing hundreds of logical gate operations. Their system is the first demonstration of large-scale algorithm execution on an error-corrected quantum computer, heralding the advent of early fault-tolerant, or reliably uninterrupted, quantum computation.
Published New genes can arise from nothing
(via sciencedaily.com) Original source The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers resolved outstanding questions regarding the origin of small regulatory genes, and described a mechanism that creates their DNA palindromes. Under suitable circumstances, these palindromes evolve into microRNA genes.
