Published Sweet success: Sugarcane's complex genetic code cracked
(via sciencedaily.com) Original source Scientists created a highly accurate reference genome for one of the most important modern crops and found a rare example of how genes confer disease resistance in plants. Exploring sugarcane's genetic code could help researchers develop more resilient and productive crops, with implications for both sugar production and biofuels.
Published A solar cell you can bend and soak in water
(via sciencedaily.com) Original source Researchers have developed an organic photovoltaic film that is both waterproof and flexible, allowing a solar cell to be put onto clothes and still function correctly after being rained on or even washed.
Published Scientists extract genetic secrets from 4,000-year-old teeth to illuminate the impact of changing human diets over the centuries
(via sciencedaily.com) Original source Researchers have recovered remarkably preserved microbiomes from two teeth dating back 4,000 years, found in an Irish limestone cave. Genetic analyses of these microbiomes reveal major changes in the oral microenvironment from the Bronze Age to today. The teeth both belonged to the same male individual and also provided a snapshot of his oral health.
Published New technique for predicting protein dynamics may prove big breakthrough for drug discovery
(via sciencedaily.com) Original source Understanding the structure of proteins is critical for demystifying their functions and developing drugs that target them. To that end, a team of researchers has developed a way of using machine learning to rapidly predict multiple protein configurations to advance understanding of protein dynamics and functions.
Published Heat, cold extremes hold untapped potential for solar and wind energy
(via sciencedaily.com) Original source Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected energy grid regions of the U.S. from 1980-2021, also found that every region experienced power outages during these events in the past decade. The findings suggest that using more renewable energy at these times could help offset increased power demand as more people and businesses turn on heaters or air conditioners.
Published New enzymatic cocktail can kill tuberculosis-causing mycobacteria
(via sciencedaily.com) Original source An enzymatic cocktail can kill a variety of mycobacterial species of bacteria, including those that cause tuberculosis.
Published Old immune systems revitalized in mouse study, improving vaccine response
(via sciencedaily.com) Original source Those with aging immune systems struggle to fight off novel viruses and respond weakly to vaccination. Researchers were able to revitalize the immune system in mice.
Published Researchers show that introduced tardigrade proteins can slow metabolism in human cells
(via sciencedaily.com) Original source Tardigrade proteins are potential candidates in technologies centered on slowing the aging process and in long-term storage of human cells.
Published Severe hurricanes boost influx of juveniles and gene flow in a coral reef sponge
(via sciencedaily.com) Original source A study is the first to evaluate substrate recolonization by sponges in the U.S. Virgin Islands after two catastrophic storms using genetic analyses to understand how much clonality verses sexual recruitment occurs on coral reefs post-storms. Results show that populations of clonal marine species with low pelagic dispersion, such as A. cauliformis, may benefit from increased frequency and magnitude of hurricanes to maintain genetic diversity and combat inbreeding, enhancing the resilience of Caribbean sponge communities to extreme storm events.
Published Discovery of amino acid unveils how light makes plants open
(via sciencedaily.com) Original source Scientists have uncovered a unique mechanism that regulates the opening of stomata in plants. Phosphorylation of the amino acid Thr881 on the plasma membrane proton pump plays a key role in this process. The study paves the way for the targeted manipulation of plant physiology, with potential applications in agriculture and environmental sustainability.
Published Research lights up process for turning CO2 into sustainable fuel
(via sciencedaily.com) Original source Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
Published Novel electrochemical sensor detects dangerous bacteria
(via sciencedaily.com) Original source Researchers have developed a novel sensor for the detection of bacteria. It is based on a chip with an innovative surface coating. This ensures that only very specific microorganisms adhere to the sensor -- such as certain pathogens. The larger the number of organisms, the stronger the electric signal generated by the chip. In this way, the sensor is able not only to detect dangerous bacteria with a high level of sensitivity but also to determine their concentration.
Published Pairing crypto mining with green hydrogen offers clean energy boost
(via sciencedaily.com) Original source Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
Published Researchers take major step toward developing next-generation solar cells
(via sciencedaily.com) Original source Engineers have discovered a new way to manufacture solar cells using perovskite semiconductors. It could lead to lower-cost, more efficient systems for powering homes, cars, boats and drones.
Published Revolutionizing hydrogen production: Economical and efficient solutions unveiled
(via sciencedaily.com) Original source Scientists introduce superaerophobic three-dimensional nickel nanostructured catalysts for accelerated water electrolysis.
Published Natural recycling at the origin of life
(via sciencedaily.com) Original source How was complex life able to develop on the inhospitable early Earth? At the beginning there must have been ribonucleic acid (RNA) to carry the first genetic information. To build up complexity in their sequences, these biomolecules need to release water. On the early Earth, which was largely covered in seawater, that was not so easy to do.
Published As we age, our cells are less likely to express longer genes
(via sciencedaily.com) Original source Aging may be less about specific 'aging genes' and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers. A decline in the expression of long genes with age has been observed in a wide range of animals, from worms to humans, in various human cell and tissue types, and also in individuals with neurodegenerative disease. Mouse experiments show that the phenomenon can be mitigated via known anti-aging factors, including dietary restriction.
Published Maize genes control little helpers in the soil
(via sciencedaily.com) Original source Tiny organisms such as bacteria and fungi help to promote the health and function of plant roots. It is commonly assumed that the composition of these microbes is dependent on the properties of the soil. However, researchers have now discovered when studying different local varieties of maize that the genetic makeup of the plants also helps to influence which microorganisms cluster around the roots.
Published Decoding the plant world's complex biochemical communication networks
(via sciencedaily.com) Original source A research team has begun translating the complex molecular language of petunias. Their grammar and vocabulary are well hidden, however, within the countless proteins and other compounds that fill floral cells. Being rooted to the ground, plants can't run away from insects, pathogens or other threats to their survival. But plant scientists have long known that they do send warnings to each other via scent chemicals called volatile organic compounds.
