  • 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?
    on November 29, 2021 at 3:55 pm

    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?
    on November 27, 2021 at 6:44 am

    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.

  • Researchers get down to the molecules of disease occurrence

    A breakthrough genetic discovery from researchers at the Schulich School of Medicine & Dentistry at the University of Western Ontario is unlocking new clues about why some individuals experience early onset of neurodegenerative diseases.

  • Researchers train an AI platform to detect skin cancer
    on November 29, 2021 at 9:17 pm

    A study identifying new ways to detect skin cancer using artificial intelligence (AI) has been conducted by researchers from the University of Hawaiʻi Cancer Center. Investigators successfully created and trained an AI platform to classify different types of skin lesions. Their findings were published in the December issue of Melanoma Research.

  • Do official vital records of maternal death detect specific effects of new pandemic viruses?
    on November 29, 2021 at 8:44 pm

    Emerging viruses can adversely affect women’s health, leading to an increase in both complications and deaths during pregnancy, childbirth and the puerperium. This is indicated by a population-based natural experiment on the 2009 H1N1 influenza pandemic and conducted on the basis of national vital Argentine records of maternal deaths. The research was published in The Lancet Regional Health—Americas.

  • Heart repair and regeneration after a heart attack: A review
    on November 29, 2021 at 8:44 pm

    Twenty years ago, clinicians first attempted to regenerate a failing human heart by injecting muscle myoblasts into the heart during a bypass operation. Despite high initial hopes and multiple experimental and clinical studies since then, outcomes have been neutral or marginally positive for a wide variety of attempts to remuscularize an injured heart.
