Published Research catalogs greenhouse gas emissions tied to energy use for interbasin water transfers
(via sciencedaily.com) Original source Much of the water in the West is transported across vast geographical areas by large infrastructure projects known as interbasin water transfers. Two of these projects in particular make up 85% of all energy-related greenhouse gas emissions associated with U.S. interbasin transfers -- one in Arizona and the other in California -- according to the new research.
Published Sustainable and reversible 3D printing method uses minimal ingredients and steps
(via sciencedaily.com) Original source A new 3D printing method developed by engineers is so simple that it uses a polymer ink and salt water solution to create solid structures. The work has the potential to make materials manufacturing more sustainable and environmentally friendly.
Published Multiple urinary metals play key role in cardiovascular disease and mortality, study finds
(via sciencedaily.com) Original source Higher levels of urinary metals such as cadmium, tungsten, uranium, cobalt, copper and zinc are linked to increased cardiovascular disease and mortality in a racially and ethnically diverse U.S. population, according to a new study.
Published Which strains of tuberculosis are the most infectious?
(via sciencedaily.com) Original source Highly localized TB strains are less infectious in cosmopolitan cities and more likely to infect people from the geographic area that is the strain's natural habitat. The research provides the first controlled evidence that TB strains may evolve with their human hosts, adapting to be more infectious to specific populations. The findings offer new clues for tailoring preventive treatments after exposure to TB based on affinity between strains host populations.
Published Novel nanosensing technique for quality control of viral vectors in gene therapy
(via sciencedaily.com) Original source Researchers develop a nanosensing platform that can assess the quality of individual viral vector particles Viral vectors hold much potential for gene editing and gene therapy, but there is a pressing need to develop quality control methods to minimize potential side effects on patients. Addressing this, researchers from Japan developed a nanosensing-based approach that can differentiate between functional and faulty viral vectors at the single-particle level. This convenient and inexpensive technique will hopefully get us one step closer to advancing treatments for genetic disorders.
Published Breakthrough in plant disease: New enzyme could lead to anti-bacterial pesticides
(via sciencedaily.com) Original source Scientists uncover a pivotal enzyme, XccOpgD, and its critical role in synthesizing C G16, a key compound used by Xanthomonas pathogens to enhance their virulence against plants. This breakthrough opens new avenues for developing targeted pesticides that combat plant diseases without harming beneficial organisms. Insights into XccOpgD's enzymatic mechanism and optimal conditions offer promising prospects for sustainable agriculture, bolstering crop resilience and global food security while minimizing environmental impact.
Published Cheese of the future: Consumers open to animal-free alternatives
(via sciencedaily.com) Original source Companies and institutes are currently working on biotechnological processes for the production of 'dairy products' without the use of cows: In so-called precision fermentation, egg and milk proteins are produced with the help of bacteria, yeasts or other fungi. This results in foods such as milk or cheese with a familiar flavor and texture. Supporters hope that this will lead to more sustainable food production, as nutrient-rich proteins can be produced using fewer resources. But will consumers accept such products?
Published Talking about regeneration
(via sciencedaily.com) Original source Researchers transferred genes from simple organisms capable of regenerating their bodies into common fruit flies, more complex animals that cannot. They found the transferred gene suppressed an age-related intestinal issue in the flies. Their results suggest studying genes specific to animals with high regenerative capability may uncover new mechanisms for rejuvenating stem cell function and extending the healthy lifespan of unrelated organisms.
Published Warming stops tiny organisms working together
(via sciencedaily.com) Original source Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
Published Study examines effect of fish oil in older adults' brains
(via sciencedaily.com) Original source A clinical trial suggests that a subset of older adults with a genetic predisposition to Alzheimer's disease may benefit from fish oil supplements.
Published Mass extinction 66 million years ago triggered rapid evolution of bird genomes
(via sciencedaily.com) Original source Study finds that the mass extinction caused by an asteroid about 66 million years ago led to critical changes in bird genomes that ultimately sparked the incredibly diversity living birds.
Published The next generation of RNA chips
(via sciencedaily.com) Original source An international research team has succeeded in developing a new version of RNA building blocks with higher chemical reactivity and photosensitivity. This can significantly reduce the production time of RNA chips used in biotechnological and medical research. The chemical synthesis of these chips is now twice as fast and seven times more efficient.
Published Underwater mapping reveals new insights into melting of Antarctica's ice shelves
(via sciencedaily.com) Original source Clues to future sea level rise have been revealed by the first detailed maps of the underside of a floating ice shelf in Antarctica. An international research team deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica.
Published Scientists devise method to secure Earth's biodiversity on the moon
(via sciencedaily.com) Original source New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.
Published Barriers designed to prevent saltwater intrusion may worsen inland flooding
(via sciencedaily.com) Original source Building protection barriers without accounting for potential inland flooding risks from groundwater can eventually worsen the very issues they aim to solve.
Published Cracking the carb code: Researchers create new glycemic index database to improve dietary awareness
(via sciencedaily.com) Original source Researchers create the first national glycemic index database, revealing how common foods impact health and contribute to chronic diseases.
Published AI opens door to safe, effective new antibiotics to combat resistant bacteria
(via sciencedaily.com) Original source In a hopeful sign for demand for more safe, effective antibiotics for humans, researchers have leveraged artificial intelligence to develop a new drug that already is showing promise in animal trials.
Published New principle for treating tuberculosis
(via sciencedaily.com) Original source Researchers have succeeded in identifying and synthesizing a group of molecules that can act against the cause of tuberculosis in a new way. They describe that the so-called callyaerins act against the infectious disease by employing a fundamentally different mechanism compared to antibiotic agents used to date.
Published Green hydrogen: 'Artificial leaf' becomes better under pressure
(via sciencedaily.com) Original source Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.
Published Scientists capture immune cells hidden in nasal passages
(via sciencedaily.com) Original source Scientists uncover 'striking' immune cell populations poised to fight SARS-CoV-2 in upper airway.
