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 From genes to jeans: New genetic insights may lead to drought resilient cotton
(via sciencedaily.com) Original source Cotton is woven into the very fabric of our lives, from soft T-shirts to comfortable jeans and cozy bedsheets. It's the world's leading renewable textile fiber and the backbone of a global industry worth billions. As climate change intensifies, cotton farmers face increasing challenges from drought and heat. However, new research offers hope for developing more resilient varieties that can maintain high yields even under water-stressed conditions.
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 New progress in research into malignant catarrhal fever in cattle
(via sciencedaily.com) Original source A research team has published a groundbreaking study on malignant catarrhal fever (MCF). This disease is caused by the alcelaphine gammaherpesvirus 1 (AlHV-1), which infects its natural host, the wildebeest. This study sheds light on the mechanisms by which this virus, which is asymptomatic and latent in the wildebeest, causes an oligoclonal expansion of CD8+ T lymphocytes in cattle, leading to the development of MCF.
Published Researchers decipher new molecular mechanisms related to biological tissue regeneration
(via sciencedaily.com) Original source A study opens new perspectives to better understand how the molecular mechanisms involved in regenerative medicine work. The study focuses on tumor necrosis factor- (TNF- ) and its receptors TNFR, molecules of key interest in biomedicine due to their involvement in multiple diseases such as obesity related to type 2 diabetes mellitus, inflammatory bowel disease and several types of cancer.
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 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 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 Scientists identify key protein behind spread of shingles virus
(via sciencedaily.com) Original source Scientists have discovered a new evasion strategy used by the varicella zoster virus, which causes chickenpox and shingles, that may allow it to affect tissues far from the original site of infection.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine
(via sciencedaily.com) Original source Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published Next-gen cooling system to help data centers become more energy efficient
(via sciencedaily.com) Original source Artificial intelligence (AI) is hot right now. Also hot: the data centers that power the technology. And keeping those centers cool requires a tremendous amount of energy. The problem is only going to grow as high-powered AI-based computers and devices become commonplace. That's why researchers are devising a new type of cooling system that promises to dramatically reduce energy demands.
Published Researchers are closing in on a mouse model for late-onset Alzheimer's
(via sciencedaily.com) Original source Researchers are working to create the first strain of mice that's genetically susceptible to late-onset Alzheimer's, with potentially transformative implications for dementia research.
Published Research sheds light on the role of PTPRK in tissue repair and cancer
(via sciencedaily.com) Original source New research has advanced our knowledge of multiple roles for PTPRK, a receptor tyrosine phosphatase linked to the regulation of cell-cell adhesion, growth factor signalling and tumor suppression. Through a characterization of the function of PTPRK in human cell lines and mice, the team distinguished catalytic and non-catalytic functions of PTPRK. The findings extend what is known about the signalling mechanisms involving PTPRK as a phosphatase and its role in colorectal health but also shed new light on the extent of its function via non-catalytic signalling mechanisms.
Published Under pressure: How cells respond to physical stress
(via sciencedaily.com) Original source Cell membranes play a crucial role in maintaining the integrity and functionality of cells. However, the mechanisms by which they perform these roles are not yet fully understood. Scientists have used cryo-electron microscopy to observe how lipids and proteins at the plasma membrane interact and react to mechanical stress.
