问题     It seems like everything is going【C1】________ these days. That now includes efforts to reprogram the human genome.
    A new University at Buffalo-【C2】________ study describes how researchers wirelessly controlled FGFR1 — a gene that plays a key role【C3】________ how humans grow from embryos to adults — in lab-grown brain tissue.
    The ability to manipulate the gene, the study’s authors say, could lead to new cancer treatments, and ways to prevent and treat mental disorders such as schizophrenia.
    The work —【C4】________ by UB researchers Josep M. Jornet, Michal K. Stachowiak, Yongho Bae and Ewa K. Stachowiak — was reported in the June edition of the Proceedings of the Institute of Electrical and Electronics Engineers.
    It represents a step【C5】________ toward genetic manipulation technology that could upend the treatment of cancer, as well as the prevention and treatment of schizophrenia and other neurological illnesses. It centers on the creation of a new subfield of research the study’s authors are calling "optogenomics," or controlling the human genome through laser light and nanotechnology.
    "The potential of optogenomic【C6】________ is enormous," says co-author Josep M. Jornet, PhD, associate professor in the Department of Electrical Engineering in the UB School of Engineering and Applied Sciences. "It could【C7】________ reduce the need for medicinal drugs and other therapies for certain illnesses. It could also change【C8】________ humans interact with machines."
    For the past 20 years, scientists have been combining optics and genetics — the field of optogenetics — with a goal of【C9】________ light to control how cells interact with each other.
    By doing this, one could potentially develop new treatments for diseases by correcting the miscommunications that occur between cells.【C10】________ promising, this research does not directly address malfunctions in genetic blueprints that guide human growth and underlie many diseases.
