    New research on Probiotics in the Prevention and Treatment of Colon Cancer

    September 15, 2017, Categories  Health/Medical, Biology/Biotechnology

    Figure shows presence of colonic tumors (MRS/AOM+DSS panel) by positron emission tomography imaging. Tumor activity is significantly diminished in the presence of the histamine-producing probiotic (L. reuteri 6475/AOM+DSS).

    Figure shows presence of colonic tumors (MRS/AOM+DSS panel) by positron emission tomography imaging. Tumor activity is significantly diminished in the presence of the histamine-producing probiotic (L. reuteri 6475/AOM+DSS).

    Histamine-producing probiotic reduces inflammation and suppresses colon tumors in mice by supplying missing enzyme, according to report. In an innovative approach to colorectal cancer (CRC) prevention and treatment, scientists are studying ways to replace missing metabolites in patients prone to gut inflammation and CRC. A new study in The American Journal of Pathology describes how administration of histamine-producing gut microbes to mice lacking the enzyme histidine decarboxylase (HDC) reduced inflammation and tumor formation...

    Experimental schematic of the hybrid system and ToF apparatus. (A) A schematic of the experimental apparatus, including the LQT, the high voltage pulsing scheme (shown as solid and dashed lines), and the ToF. (B) An illustrative experimental time sequence that depicts initialization of a Ba+ crystal, production of BaOCH3 + (visualized as dark ions in the crystal) through reactions with methanol vapor, and subsequent MOT immersion. (C) Sample mass spectra obtained after ejecting the LQT species into the ToF after various MOT immersion times, ti, along with an inset depicting a superimposed fluorescence image of an ion crystal immersed in the Ca MOT. (D) Mass spectra of photofragmentation products collected after inducing photodissociation of BaOCa+ . The identified photofragments were used to verify the elemental composition of the product.

    UH researchers discover new form of stretchable electronics, sensors and skins, allowing a robotic hand to sense the difference between hot and cold, while also offering advantages for a wide range of biomedical devices. The work, reported in the journal Science Advances, describes a new mechanism for producing stretchable electronics, a process that relies upon readily available materials and could be scaled up for commercial production.

    First Global Map of Water in Moon’s Soil

    September 15, 2017, Categories  Astronomy/Space

    A new map reveals quantities of water trapped in the lunar soil. The amounts increase toward the poles, suggesting that much of the water was implanted by the solar wind (yellow dots mark Apollo landing sites). Credit: Milliken lab / Brown University

    In research that may prove useful to future lunar explorers, scientists from Brown University have created the first quantitative map of water and its chemical building blocks trapped in the uppermost portion of the Moon’s soil. The study builds on the initial discovery in 2009 of water and a related molecule – hydroxyl – in the lunar soil. The latest study uses a new calibration of data taken from NASA’s Moon Mineralogy Mapper, which flew aboard India’s Chandrayaan-1 spacecraft, to quantify how much water is present on a global scale.
