WASHINGTON D.C., Sept. 6, 2024 — An exploration into quantum effects produced in nanoscale biological processes has the potential to upend traditional perceptions of the causes and effects of Alzheimer’s disease and other neurological conditions. Researchers have discovered that when tryptophan, an amino acid that is a fundamental building block of certain proteins, collects in a structural network within neural fibers, it can collect harmful ultraviolet light and release it at biologically safe intensities. The scientists at the Quantum Biology Laboratory at Howard University have focused their recent...Read full article

    Glossary
    quantum
    The term quantum refers to the fundamental unit or discrete amount of a physical quantity involved in interactions at the atomic and subatomic scales. It originates from quantum theory, a branch of physics that emerged in the early 20th century to explain phenomena observed on very small scales, where classical physics fails to provide accurate explanations. In the context of quantum theory, several key concepts are associated with the term quantum: Quantum mechanics: This is the branch of...
    photon
    A quantum of electromagnetic energy of a single mode; i.e., a single wavelength, direction and polarization. As a unit of energy, each photon equals hn, h being Planck's constant and n, the frequency of the propagating electromagnetic wave. The momentum of the photon in the direction of propagation is hn/c, c being the speed of light.
    superradiance
    Directional and coherent radiation pulses that result from an ensemble of coherently prepared states in an optical medium.
    ultraviolet
    That invisible region of the spectrum just beyond the violet end of the visible region. Wavelengths range from 1 to 400 nm.
    phototoxicity
    Phototoxicity refers to the harmful effects caused by exposure to light, particularly intense or ultraviolet (UV) light, on living cells or organisms. This phenomenon is often associated with the interaction of light with certain substances, known as photosensitizers, which can lead to cellular damage or death. Phototoxic reactions can occur in various biological systems, including cells, tissues, and organisms. Key points about phototoxicity include: Photosensitizers: Photosensitizers are...
