Published New technique offers more precise maps of the Moon's surface
(via sciencedaily.com) Original source A new study may help redefine how scientists map the surface of the Moon, making the process more streamlined and precise than ever before.
Published Heart healthy behaviors may help reverse rapid cell aging
(via sciencedaily.com) Original source The benefits gained with higher lifestyle scores may be associated with the positive influence of heart disease risk factors on the aging of the body and its cells, finds a new study in the Journal of the American Heart Association
Published Bird flu: Diverse range of vaccines platforms 'crucial' for enhancing human pandemic preparedness
(via sciencedaily.com) Original source Review of research to-date suggests vaccination remains the most effective strategy for avian influenza prevention and control in humans, despite varying vaccine efficacy across strains.
Published Intermittent fasting shows promise in improving gut health, weight management
(via sciencedaily.com) Original source Participants following an intermittent fasting and protein-pacing regimen, which involves evenly spaced protein intake throughout the day, saw better gut health, weight loss and metabolic responses. These benefits were notably greater than those seen with simple calorie restriction. The findings could advance our understanding of the relationship between the gut microbiome and metabolism and improve strategies for managing obesity.
Published Scientists identify gene that could lead to resilient 'pixie' corn
(via sciencedaily.com) Original source A widely found gene in plants has been newly identified as a key transporter of a hormone that influences the size of corn. The discovery offers plant breeders a new tool to develop desirable dwarf varieties that could enhance the crop's resilience and profitability.
Published When should you neuter or spay your dog?
(via sciencedaily.com) Original source A new study updates guidelines for when you should neuter or spay your dog to prevent increased risk of cancer or joint disorders.
Published Bringing back an ancient bird
(via sciencedaily.com) Original source Using ancient DNA extracted from the toe bone of a museum specimen, biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. The work is the first complete genetic map of the turkey-sized bird whose distant living cousins include the ostrich, emu, and kiwi.
Published Mechanisms for selective multiple sclerosis treatment strategy
(via sciencedaily.com) Original source Researchers have demonstrated how B cells infected with the Epstein-Barr virus (EBV) can contribute to a pathogenic, inflammatory phenotype that contributes to multiple sclerosis (MS); the group has also shown how these problematic B cells can be selectively targeted in a way that reduces the damaging autoimmune response of multiple sclerosis.
Published 'Cloaked' proteins deliver cancer-killing therapeutics into cells
(via sciencedaily.com) Original source Scientists have designed a way to 'cloak' proteins in a generalized technique that could lead to repurposing things like antibodies for biological research and therapeutic applications.
Published Scientists uncover a multibillion-year epic written into the chemistry of life
(via sciencedaily.com) Original source Life evolved from simple geochemical processes present on the early Earth. However, the details of this transformation remain a mystery. In this study, researchers modeled the emergence of metabolic pathways from simple geochemical precursors and concluded that surprisingly few reactions in the history of metabolism may have been lost to time.
Published Mystery of 'slow' solar wind unveiled by Solar Orbiter mission
(via sciencedaily.com) Original source Scientists have come a step closer to identifying the mysterious origins of the 'slow' solar wind, using data collected during the Solar Orbiter spacecraft's first close journey to the Sun.
Published Genetic mosaicism more common than thought
(via sciencedaily.com) Original source Researchers found that approximately one in 40 human bone marrow cells carry massive chromosomal alterations without causing any apparent disease or abnormality. Even so-called normal cells carry all sorts of genetic mutations, meaning there are more genetic differences between individual cells in our bodies than between different human beings. The discovery was enabled by a single-cell sequencing technology called Strand-seq, a unique DNA sequencing technique that can reveal subtle details of genomes in single cells that are too difficult to detect with other methods.
Published Researchers have unveiled a new method to manipulate cell movement in embryos
(via sciencedaily.com) Original source Scientists have developed a new method that can manipulate the movement of embryonic cells using short-time attractors.
Published How killifish embryos use suspended animation to survive over 8 months of drought
(via sciencedaily.com) Original source The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish's embryos enter a state of extreme suspended animation or 'diapause' for approximately 8 months. Now, researchers have uncovered the mechanisms that enabled the killifish to evolve this extreme survival state.
Published Transgenic expression of rubisco factors increases photosynthesis and chilling tolerance in maize
(via sciencedaily.com) Original source Maize is one of the world's most widely grown crops and is essential to global food security. But like other plants, its growth and productivity can be limited by the slow activity of Rubisco, the enzyme responsible for carbon assimilation during photosynthesis. Scientists have now demonstrated a promising approach to enhancing Rubisco production, thus improving photosynthesis and overall plant growth.
Published Secrets of sargassum: Scientists advance knowledge of seaweed causing chaos in the Caribbean and West Africa
(via sciencedaily.com) Original source A research team tracked and studied floating sargassum in order to unlock its potential to be used to produce sustainable products.
Published Observing mammalian cells with superfast soft X-rays
(via sciencedaily.com) Original source Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.
Published New approach to Epstein-Barr virus and resulting diseases
(via sciencedaily.com) Original source The Epstein-Barr virus can cause a spectrum of diseases, including a range of cancers. Emerging data now show that inhibition of a specific metabolic pathway in infected cells can diminish latent infection and therefore the risk of downstream disease.
Published New 'atlas' provides unprecedented insights on how genes function in early embryo development
(via sciencedaily.com) Original source Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers captured unprecedented insights on how embryonic development unfolds.
Published Intriguing nearby world sized between Earth, Venus
(via sciencedaily.com) Original source Astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away.
