Published Network of quantum sensors boosts precision
(via sciencedaily.com) Original source Quantum sensor technology promises even more precise measurements of physical quantities. A team has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.
Published Unraveling the mystery of chiton visual systems
(via sciencedaily.com) Original source You'd probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if it's one of the species with eyes dotting its platemail shell.
Published New antibodies target 'dark side' of influenza virus protein
(via sciencedaily.com) Original source Researchers have identified antibodies targeting a hard-to-spot region of the influenza virus, shedding light on the relatively unexplored 'dark side' of the neuraminidase (NA) protein head. The antibodies target a region of the NA protein that is common among many influenza viruses, including H3N2 subtype viruses, and could be a new target for countermeasures.
Published Convergent evolution of algal CO2-fixing organelles
(via sciencedaily.com) Original source Researchers identified the proteins of a CO2-fixing organelle, namely, 'pyrenoid,' in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal groups, suggesting the independent evolution of pyrenoids in different algal groups.
Published AI-enabled atomic robotic probe to advance quantum material manufacturing
(via sciencedaily.com) Original source Scientists have pioneered a new methodology of fabricating carbon-based quantum materials at the atomic scale by integrating scanning probe microscopy techniques and deep neural networks. This breakthrough highlights the potential of implementing artificial intelligence at the sub-angstrom scale for enhanced control over atomic manufacturing, benefiting both fundamental research and future applications.
Published Scientists make nanoparticles dance to unravel quantum limits
(via sciencedaily.com) Original source The question of where the boundary between classical and quantum physics lies is one of the longest-standing pursuits of modern scientific research and in new research, scientists demonstrate a novel platform that could help us find an answer.
Published Study identifies multi-organ response to seven days without food
(via sciencedaily.com) Original source New findings reveal that the body undergoes significant, systematic changes across multiple organs during prolonged periods of fasting. The results demonstrate evidence of health benefits beyond weight loss, but also show that any potentially health-altering changes appear to occur only after three days without food.
Published It's not only opposites that attract -- new study shows like-charged particles can come together
(via sciencedaily.com) Original source A study shows that similarly charged particles can sometimes attract, rather than repel. The team found that like-charged particles suspended in liquids can attract one another at long-range, depending on the solvent and the sign of the charge. The study has immediate implications for processes that involve interactions in solution across various length-scales, including self-assembly, crystallization, and phase separation.
Published Light into the darkness of photosynthesis
(via sciencedaily.com) Original source Researchers succeed at generating 3D visualizations of chloroplasts' copying machines.
Published How virus causes cancer: Potential treatment
(via sciencedaily.com) Original source Researchers have discovered a key mechanism used by Kaposi's sarcoma-associated herpesvirus (KSHV), also known as human herpesvirus 8 (HHV8), to induce cancer. The research points to effective new treatment options for KSHV-associated cancers, including Kaposi's sarcoma, primary effusion lymphoma, and HHV8-associated multicentric Castleman disease.
Published Scientists ID burned bodies using technique used for extracting DNA from woolly mammoths, Neanderthals
(via sciencedaily.com) Original source A technique originally devised to extract DNA from woolly mammoths and other ancient archaeological specimens can be used to potentially identify badly burned human remains, according to research.
Published New role for bacterial enzyme in gut metabolism revealed
(via sciencedaily.com) Original source Bile acids long have been known to play a role in human metabolism. Synthesized from cholesterol in the liver, bile acids are involved in digestive processes, particularly in absorbing fat. They also are modified extensively by bacteria, which greatly expand the types of bile acids found in the host. For most of a century, scientists believed that was the end of the bile-acid story. Recent technological advances, however, have led to a greater understanding of the origins of bile acids as well as their chemical relationships to the organisms in the gut microbiome and their host.
Published Scientists identify new 'regulatory' function of learning and memory gene common to all mammalian brain cells
(via sciencedaily.com) Original source Neuroscientists say they have found a new function for the SYNGAP1 gene, a DNA sequence that controls memory and learning in mammals, including mice and humans.
Published Cyber-physical heating system may protect apple blossoms in orchards
(via sciencedaily.com) Original source Spring frosts can have devastating effects on apple production, and a warming climate may be causing trees to blossom early, making them more susceptible to the damaging effects of extreme cold events. Growers' attempts to prevent the flowers from freezing by attempting to heat the canopies of their orchards largely have been inefficient.
Published Microbial viruses act as secret drivers of climate change
(via sciencedaily.com) Original source Scientists have discovered that viruses that infect microbes contribute to climate change by playing a key role in cycling methane, a potent greenhouse gas, through the environment.
Published Shining a light on the effects of habituation and neural adaptation on the evolution of animal signals
(via sciencedaily.com) Original source A new paper examines the possible effects of two properties of receiver playing fields documented in studies of animal psychology -- habituation and neural adaptation -- on the efficacy of mate choice signals.
Published Scientists discover 18 new species of gut microbes in search for origins of antibiotic resistance
(via sciencedaily.com) Original source Researchers have discovered 18 new species of Enterococcus type bacteria from soil samples collected from all corners of the globe, which may offer new clues to the origins of antibiotic-resistant infections in hospitals.
Published AI technique 'decodes' microscope images, overcoming fundamental limit
(via sciencedaily.com) Original source Researchers have developed a deep learning algorithm for removing systematic effects from atomic force microscopy images, enabling more precise profiles of material surfaces.
Published Building bionic jellyfish for ocean exploration
(via sciencedaily.com) Original source Researchers show how biohybrid robots based on jellyfish could be used to gather climate science data from deep in the Earth's oceans.
Published Effect of keratin microsphere gel on hair growth in mice
(via sciencedaily.com) Original source Keratin microsphere gel, consisting of keratin-based microspheres that swell in water to form a gel, has shown efficacy in promoting hair follicle growth in murine models. Its potential application as an active ingredient in hair regrowth treatments with minimal side effects is anticipated.
