Published Platypus and chicken reveal how chromosomes balance between the sexes
(via sciencedaily.com) Original source Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene regulation.
Published How researchers turn bacteria into cellulose-producing mini-factories
(via sciencedaily.com) Original source Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.
Published Dark matter: A camera trap for the invisible
(via sciencedaily.com) Original source AI-powered image recognition could give researchers a new tool in hunt for dark matter.
Published Shape-shifting 'transformer bots' inspired by origami
(via sciencedaily.com) Original source Inspired by the paper-folding art of origami, engineers have discovered a way to make a single plastic cubed structure transform into more than 1,000 configurations using only three active motors.
Published Robotics: Self-powered 'bugs' can skim across water to detect environmental data
(via sciencedaily.com) Original source Researchers have developed a self-powered 'bug' that can skim across the water, and they hope it will revolutionize aquatic robotics.
Published Faster, cleaner way to extract lithium from battery waste
(via sciencedaily.com) Original source Researchers uncover a rapid, efficient and environmentally friendly method for selective lithium recovery using microwave radiation and a readily biodegradable solvent.
Published AI method radically speeds predictions of materials' thermal properties
(via sciencedaily.com) Original source Researchers developed a machine-learning framework that can predict a key property of heat dispersion in materials that is up to 1,000 times faster than other AI methods, and could enable scientists to improve the efficiency of power generation systems and microelectronics.
Published Win-win potential of grass-powered energy production
(via sciencedaily.com) Original source Researchers modeled the impact of using anaerobic digestion to produce renewable natural gas from grassy biomass in different settings and from varying perspectives, analysis that helps flesh out the system's potential.
Published Fresh light on the path to net zero
(via sciencedaily.com) Original source Researchers have used magnetic fields to reveal the mystery of how light particles split. Scientists are closer to giving the next generation of solar cells a powerful boost by integrating a process that could make the technology more efficient by breaking particles of light photons into small chunks.
Published The ancestor of all modern birds probably had iridescent feathers
(via sciencedaily.com) Original source Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
Published Lampreys possess a 'jaw-dropping' evolutionary origin
(via sciencedaily.com) Original source Lampreys are one of only two living jawless vertebrates Jaws are formed by a key stem cell population called the neural crest New research reveals the gene regulatory changes that may explain morphological differences between jawed and jawless vertebrates.
Published Climate change will bring more turbulence to flights in the Northern Hemisphere, study finds
(via sciencedaily.com) Original source A type of invisible, unpredictable air turbulence is expected to occur more frequently in the Northern Hemisphere as the climate warms. Known as clear air turbulence, the phenomenon also increased in the Northern Hemisphere between 1980 and 2021.
Published Chemical analyses find hidden elements from renaissance astronomer Tycho Brahe's alchemy laboratory
(via sciencedaily.com) Original source Danish Tycho Brahe was most famous for his contributions to astronomy. However, he also had a well-equipped alchemical laboratory where he produced secret medicines for Europe's elite.
Published New battery-free technology to power electronic devices using ambient radiofrequency signals
(via sciencedaily.com) Original source Researchers demonstrated a novel technique to efficiently convert ambient low-power radiofrequency signals into DC power. This 'rectifier' technology can be easily integrated into energy harvesting modules to power electronic devices and sensors, enabling battery-free operation.
Published Energy planning in Ghana as a role model for the world
(via sciencedaily.com) Original source Researchers are investigating ways to better plan for climate-resilient energy systems in the Global South. Focusing on the case study of Accra, the capital of Ghana, the multidisciplinary team expanded conventional energy system modeling approaches by incorporating a range of socio-techno-economic challenges, climate change impacts, and resilience metrics into their models. Their approaches are applicable worldwide to support widespread sustainable and resilient energy system transitions.
Published Ancient marine animal had inventive past despite being represented by few species
(via sciencedaily.com) Original source Brachiopods were evolving in new directions but this did not turn into evolutionary success in terms of the numbers of species, researchers have found.
Published Exploring consciousness with eureka moments
(via sciencedaily.com) Original source We all know what it's like when the penny suddenly drops. Animals too experience such moments of insight. They could prove useful for research of consciousness.
Published Rock art and archaeological record reveal humans' complex relationship with Amazonian animals
(via sciencedaily.com) Original source Rock art explored by archaeologists in the Colombian Amazon has provided an insight into the complex relationship between the earliest settlers on the continent and the animals they encountered.
Published Artificial blood vessels could improve heart bypass outcomes
(via sciencedaily.com) Original source 3D-printed blood vessels, which closely mimic the properties of human veins, could transform the treatment of cardiovascular diseases. Strong, flexible, gel-like tubes -- created using a novel 3D printing technology -- could improve outcomes for heart bypass patients by replacing the human and synthetic veins currently used in surgery to re-route blood flow, experts say.
Published In clinical trial, fecal matter transplant helped half of patients with gastrointestinal cancers overcome resistance to immunotherapy treatment
(via sciencedaily.com) Original source Findings from a small, proof-of-concept clinical trial have suggested that fecal microbiota transplants (FMTs) can boost the effectiveness of immunotherapy in a range of gastrointestinal cancers. In the study, six of 13 patients who had previously shown resistance to immune checkpoint inhibitors benefited from receiving FMTs from donors who had previously responded to treatment. The investigators also identified specific strains of bacteria associated with better or worse responses to FMT and immune checkpoint drugs.
