    Action of two protostars appears to be making conditions right for planet formation
    Left: ALMA 1.3 mm observations toward the triple class 0 system IRAS 16293–2422. The observations have a resolution of ∼35 au and were published in Sadavoy et al. (2018). Right: ALMA 1.3 and 3 mm observations of the southern binary system at a resolution of ∼13 and ∼7 au, respectively. Similar maps for source B are presented in Zamponi et al. (2021). In all panels, the positions of the protostars are marked by stars. Additional continuum peaks around the A1 and A2 protostars are labeled and marked with plus signs in the right panels. The beam is shown in the bottom left corner of each panel. Credit: The Astrophysical Journal Letters (2022). DOI: 10.3847/2041-8213/aca53a

    Scientists uncover a Novel Cellular Mechanism that Regulates Aging and Fertility

    December 28, 2022, Categories  Health/Medical, Biology/Biotechnology

    “We have always been intrigued by the dichotomy between two diametrically opposed, fundamental phenomena in biology: soma mortality and germline immortality. The prospect of uncovering the molecular underpinnings of this sharply idiosyncratic character of cell types, within a single organism, provided ample motivation for us to embark on a research journey, towards tackling such questions. We decided to focus on nuclear morphology in somatic cells, which deteriorates during ageing. By contrast, the overall architecture of the nucleus is preserved in the germline. Our hypothesis was that a homeostatic mechanism effectively maintains the structure of germ cell nuclei, whereas it fails during ageing, in the soma...

    Emerging forms of thin-film device technologies that rely on alternative semiconductor materials, such as printable organics, nanocarbon allotropes and metal oxides, could contribute to a more economically and environmentally sustainable IoT, a KAUST-led international team suggests.

    Their paper is published in the journal Nature Electronics.

    The IoT is set to have a major impact on daily life and many industries...

    Planetary Interiors in TRAPPIST-1 System could be affected by Solar Flares

    In a recent study published in the Astrophysical Journal Letters, an international team of researchers led by the University of Cologne in Germany examined how solar flares erupted by the TRAPPIST-1 star could affect the interior heating of its orbiting exoplanets.

    This study holds the potential to help us better understand how solar flares affect planetary evolution. The TRAPPIST-1 system is an exoplanetary system located approximately 39 light-years from Earth with at least seven potentially rocky exoplanets in orbit around a star that has 12 times less mass than our own sun. Since the parent star is much smaller than our own sun, then the the planetary orbits within the TRAPPIST-1 system are much smaller than our own solar system, as well...
