Insights into healing and aging were discovered by National Institutes of Health researchers and their collaborators, who studied how a tiny sea creature regenerates an entire new body from only its mouth. The researchers sequenced RNA from Hydractinia symbiolongicarpus, a small, tube-shaped animal that lives on the shells of hermit crabs. Just as the Hydractinia were beginning to regenerate new bodies, the researchers detected a molecular signature associated with the biological process of aging, also known as senescence. According to the study published in Cell Reports, Hydractinia demonstrates that the fundamental biological processes of healing and aging are intertwined, ...

For the first time, researchers have succeeded in predicting how to change the optimum temperature of an enzyme using large computer calculations.

15N isotope-labeled amino acids (15N-amino acids) provide a safe and effective tracer tool for studying the synthesis of natural products, protein metabolism, and disease diagnosis and treatment in living organisms. In addition, it is an important synthetic block for the synthesis of 15N-labeled drugs. Currently, 15N-labeled amino acids are generally synthesized by microbial fermentation and chemical reduction amination of ketoacids, but these methods usually require complex steps, high temperature conditions or the use of toxic cyanide, causing energy and environmental ...

Subtropical mode water (STMW) is a vertically homogeneous thermocline water mass, serving as heat, carbon, and oxygen silos in the ocean interior and providing memory of climate variability for climate prediction. Understanding physics governing STMW formation is thus of broad scientific significance and has received much attention. Traditionally, it has been considered that STMW is constructed by basin-scale atmospheric forcing. Due to the limitations resulting from sparse sampling of observations and coarse ...

Multiple sclerosis (MS) is a serious neurological disease that usually causes permanent disability. Approximately 2.9 million people are affected worldwide, 240,000 in Germany alone. The exact cause of the disease is not yet clear, but a central feature is a loss of the insulating protective layer of axons – the neuronal connections in the central nervous system – which is triggered by autoimmune processes. The coating of the axons, known as myelin, is formed by highly specialised glial cells (i.e. oligodendrocytes) and enables the rapid transmission ...

Co-design, that is, designing software and hardware simultaneously, is one way of attempting to meet the computing-power needs of today’s artificial intelligence applications. Compilers, which translate instructions from one representation to another, are a key piece of the puzzle. A group of researchers at the Chinese Academy of Sciences summarized existing compiler technologies in deep learning co-design and proposed their own framework, the Buddy Compiler. The group’s review paper was published June 19 in Intelligent Computing, a Science Partner Journal. Although others have summarized optimizations, hardware architectures, co-design approaches, and compilation ...

In the first global assessment of TB among incarcerated people, a new study found consistently high TB case rates and low case detection in prisons, suggesting the need for health organizations to increase efforts to reduce the spread of TB among this high-risk population. In 2019, incarcerated people across the globe developed tuberculosis (TB) at nearly 10 times the rate of people in the general population, according to a new study led by Boston University School of Public Health (BUSPH). Published in The Lancet Public Health, the study found that 125,105 of the 11 million people incarcerated worldwide developed tuberculosis in 2019, ...

Research from Ann & Robert H. Lurie Children’s Hospital of Chicago promises to spare many premature infants from undergoing invasive eye exams to detect retinopathy of prematurity (ROP), the most common cause of preventable lifelong blindness in children in the U.S. ROP is caused by an abnormal development of small blood vessels on the retina. Isabelle De Plaen, MD, and colleagues found that imaging the capillaries in the nailbed of preemies within the first month of life using a non-invasive technique, called nailbed capillaroscopy, can identify infants at high risk for developing ROP. This screening could eliminate the need to evaluate all premature infants with eye exams ...

Air pollution is the largest environmental cause of death. Now, a study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has estimated which sources contribute most to the mortality associated with two air pollutants - PM2.5 and NO2 - in 857 European cities. The results of this research, which have been published in The Lancet Public Health, show great variability between the different cities studied, suggesting that, given that each one has its own particularities and its own sources of air pollution, strategies to improve air quality should be adapted to each local context.
