  • Researchers shrink camera to the size of a salt grain
    on November 29, 2021 at 5:27 pm

    Researchers have developed an ultracompact camera the size of a coarse grain of salt. The new system can produce crisp, full-color images on par with a conventional compound camera lens 500,000 times larger in volume.

  • Spicy breast milk?

    In part of a recent human study led by the Technical University of Munich (TUM), it was found that after eating a curry dish containing pepper, piperine – an alkaloid responsible for the pungency of pepper – was present in the milk of breastfeeding women. The findings help decipher mechanisms that shape our food preferences from infancy.

  • How can our brain still perceive familiar objects even when they become indistinct?

    Researchers have explored the brain neuronal mechanism that allows the perception of familiar images even if they are indistinct. They found that the number of neurons responding to low-contrast rather than high-contrast visual stimuli increased in rats performing a visual orientation discrimination task after repeated experiences. These neurons showed stronger activities in correct-choice than incorrect-choice trials. These neurons efficiently represented low-contrast stimulations. Thus, the low-contrast preference in V1 activity may contribute to improved low-contrast visual. discrimination.

  • Which side is which? How the brain perceives borders

    In the classic “Rubin’s vase” optical illusion, you can see either an elaborate, curvy vase or two faces, noses nearly touching. At any given moment, which scene you perceive depends on whether your brain is viewing the central vase shape to be the foreground or background of the picture.

  • COVID’s ‘not done with us’: Nations rush to contain omicron
    on November 29, 2021 at 7:08 pm

    Taking an act-now-ask-questions-later approach, countries around the world slammed their doors shut again to try to keep the new omicron variant at bay Monday as more cases of the mutant coronavirus emerged and scientists raced to figure out just how dangerous it might be.

    Spain said Monday it had detected its first case of the new Omicron strain of COVID in a man who had recently arrived from South Africa.

  • Study sheds light on how fatty liver disease turns into liver cancer
    on November 29, 2021 at 6:10 pm

    A research team with the Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences reported their discovery that a metabolic regulation mechanism may play a role in malignant transformation of non-alcoholic steatohepatitis to liver tumor.
