Published Vest can detect earlier signs of heart muscle disease
(via sciencedaily.com) Original source A reusable vest that can map the electric impulses of the heart in fine detail could detect abnormalities from a potentially fatal heart disease much earlier than is currently possible, a new study suggests.
Published Nanocarrier with escape reflex
(via sciencedaily.com) Original source Protein-based drugs must be transported into cells in a way that prevents their immediate degradation. A new approach is intended to ensure that they remain intact only in certain cells, such as cancer cells. A Japanese research team has introduced a nanocarrier that can 'escape' from endosomes before its cargo is destroyed there. This ability to escape is only triggered within the endosomes of certain tumor cells.
Published Counting rays: Aerial surveys reveal ample populations in Southeast Florida
(via sciencedaily.com) Original source A unique long-term study quantified the abundance of whitespotted eagle and giant manta rays in Southeast Florida. Researchers conducted 120 survey flights between 2014 and 2021 from Miami north to the Jupiter Inlet. One or both species were seen on nearly every flight and both populations appear to be stable in the region. The giant manta rays were more abundant in the south and the whitespotted eagle rays were found all along the coast. Neither species seems to be deterred by the greater human population density in Fort Lauderdale/Miami.
Published Double trouble at chromosome ends
(via sciencedaily.com) Original source New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought.
Published Change in gene code may explain how human ancestors lost tails
(via sciencedaily.com) Original source A genetic change in our ancient ancestors may partly explain why humans don't have tails like monkeys.
Published Walleye struggle with changes to timing of spring thaw
(via sciencedaily.com) Original source Walleye are one of the most sought-after species in freshwater sportfishing, a delicacy on Midwestern menus and a critically important part of the culture of many Indigenous communities. They are also struggling to survive in the warming waters of the Midwestern United States and Canada. According to a new study, part of the problem is that walleye are creatures of habit, and the seasons -- especially winter -- are changing so fast that this iconic species of freshwater fish can't keep up.
Published New disease testing component facilitates lower-cost diagnostics
(via sciencedaily.com) Original source Biomedical researchers have developed a new, less expensive way to detect nuclease digestion -- one of the critical steps in many nucleic acid sensing applications, such as those used to identify COVID-19 and other infectious diseases.
Published First DNA study of ancient Eastern Arabians reveals malaria adaptation
(via sciencedaily.com) Original source People living in ancient Eastern Arabia appear to have developed resistance to malaria following the appearance of agriculture in the region around five thousand years ago.
Published Low-Temperature Plasma used to remove E. coli from hydroponically grown crops
(via sciencedaily.com) Original source In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.
Published New discovery shows how cells defend themselves during stressful situations
(via sciencedaily.com) Original source A recent study has unveiled an exciting discovery about how our cells defend themselves during stressful situations. The research shows that a tiny modification in the genetic material, called ac4C, acts as a crucial defender, helping cells create protective storage units known as stress granules. These stress granules safeguard important genetic instructions when the cell is facing challenges. The new findings could help shed light on relevant molecular pathways that could be targeted in disease.
Published Visual prosthesis simulator offers a glimpse into the future
(via sciencedaily.com) Original source Researchers have developed a simulator that enables artificial visual observations for research into the visual prosthesis. This open source tool is available to researchers and offers those who are interested insight into the future application.
Published Scientists use blue-green algae as a surrogate mother for 'meat-like' proteins
(via sciencedaily.com) Original source Researchers have not only succeeded in using blue-green algae as a surrogate mother for a new protein -- they have even coaxed the microalgae to produce 'meat fiber-like' protein strands. The achievement may be the key to sustainable foods that have both the 'right' texture and require minimal processing.
Published Researchers use Hawk supercomputer and lean into imperfection to improve solar cell efficiency
(via sciencedaily.com) Original source Solar energy is one of the most promising, widely adopted renewable energy sources, but the solar cells that convert light into electricity remains a challenge. Scientists have turned to the High-Performance Computing Center Stuttgart to understand how strategically designing imperfections in the system could lead to more efficient energy conversion.
Published Microbial comics: RNA as a common language, presented in extracellular speech-bubbles
(via sciencedaily.com) Original source Decoding the conversations between microbes of hypersaline environments reveals deep insights into the origins of complex life.
Published AI-driven lab speeds catalysis research
(via sciencedaily.com) Original source Researchers have developed a 'self-driving' lab that uses artificial intelligence (AI) and automated systems to provide in-depth analyses of catalytic reactions used in chemical research and manufacturing. The new tool, called Fast-Cat, can provide more information in five days than is possible in six months of conventional testing.
Published 'Janitors' of the Sea: Overharvested sea cucumbers play crucial role in protecting coral
(via sciencedaily.com) Original source Researchers discovered that sea cucumbers -- sediment-eating organisms that function like autonomous vacuum cleaners of the ocean floor -- play an enormous role in protecting coral from disease.
Published Human stem cells coaxed to mimic the very early central nervous system
(via sciencedaily.com) Original source The first stem cell culture method that produces a full model of the early stages of the human central nervous system has been developed by a team of engineers and biologists.
Published Cutting-edge 'protein lawnmower' created
(via sciencedaily.com) Original source Scientists have designed the first synthetic protein-based motor which harnesses biological reactions to fuel and propel itself. 'Imagine if a Roomba could be powered only by the dirt it picks up,' says one of the authors of the study. The motor uses the digestive enzyme trypsin to cut the peptides and convert them into the energy it needs to propel itself.
Published Black carbon sensor could fill massive monitoring gaps
(via sciencedaily.com) Original source Black carbon is up to 25 times more hazardous to human health than other airborne particles of a similar size. Standard sensors are expensive and burdensome, resulting in sparse coverage in regions infamous for poor air quality, such as the greater Salt Lake City area. A University of Utah-led study found that a portable, more affordable sensor recorded black carbon concentrations as accurately as the most widely used instrument for monitoring black carbon in real time. The portable sensor could help expand an accurate observation network to establish disease risk and create effective public health policies.
Published A new, comprehensive roadmap for the future of biomedical engineering
(via sciencedaily.com) Original source Experts published a detailed position paper on the field of biomedical engineering which lays the foundation for a concerted worldwide effort to achieve technological and medical breakthroughs.
