    Webb Space Telescope Detects Universe’s Most Distant Complex Organic Molecules

    June 7, 2023, Categories  Astronomy/Space

    Astronomers using the Webb telescope discovered evidence of complex organic molecules in a galaxy more than 12 billion light-years away. The galaxy lines up almost perfectly with a second galaxy only 3 billion light-years away from our perspective on Earth. In this false-color Webb image, the foreground galaxy is shown in blue, while the background galaxy is red. The organic molecules are highlighted in orange.

    DNA Damage Repaired by Antioxidant Enzymes

    June 7, 2023, Categories  Health/Medical, Biology/Biotechnology

    In crisis, the nucleus calls antioxidant enzymes to the rescue. The nucleus being metabolically active is a profound paradigm shift with implications for cancer research.

    Summary points

    The human nucleus is metabolically active, according to the findings of a new study in Molecular Systems Biology by researchers at the CRG in Barcelona and CeMM/Medical University of Vienna,

    In a state of crisis, such as widespread DNA damage, the nucleus protects itself by appropriates mitochondrial machinery to carry out urgent repairs that threaten the genome’s integrity

    The findings represent a paradigm shift because the nucleus has been historically considered to be metabolically inert, importing all its needs through supply chains in the cytoplasm

    Scientists have identified a method for improving the thermal conductivity of thin metal films in semiconductors using surface waves for the first time in the world.

    The demand to shrink the size of semiconductors coupled with the problem of the heat generated at the hot spots of the devices not being effectively dispersed has negatively affected the reliability and durability of modern devices. Existing thermal management technologies have not been up to the task...

    Dying Stars’ Cocoons could be New Source of Gravitational Waves

    June 6, 2023, Categories  Astronomy/Space

    Although astrophysicists theoretically should be able to detect gravitational waves from a single, non-binary source, they have yet to uncover these elusive signals. Now researchers suggest looking at a new, unexpected and entirely unexplored place: The turbulent, energetic cocoons of debris that surround dying massive stars.

    For the first time ever, the researchers have used state-of-the-art simulations to show that these cocoons can emit gravitational waves. And, unlike gamma-ray burst jets, cocoons’ gravitational waves should be within the frequency band that the Laser Interferometer Gravitational-Wave Observatory (LIGO) can detect.

    “As of today, LIGO has only detected gravitational waves from binary systems, but one day it will detect the first non-binary source of gravitati...
