Yashvee Dunneram, an expert in nutrition and dietetics at the University of Leeds’ School of Food Science and Nutrition, led a study researching the effect of food on menopause. To perform this study, researchers gathered a…

Scientists Are Growing Human Brains in Mice

By Marcia-Ruth Ndege ‘21 Human pluripotent stem cells can differentiate into nearly any cell in the human body. Recently, geneticist Abed AlFatah Mansour and other scientists from the Salk Institute for Biological Studies used them to build human brains in mice. The differentiation of human pluripotent stem cells gave rise to small brain-like structures known…

Using Hunger to Suppress Pain

By Marcia-Ruth Ndege ‘21 Much is known about how the brain communicates needs such as thirst, hunger, pain, and fear. However, little is known about how the brain prioritizes such needs. In the context of pain, researchers must examine both acute and inflammatory pain. Acute pain is a reflexive response, while inflammatory pain is mediated…

New Findings in Telomerase Activity and the Potential for Immortality

By Marcia-Ruth Ndege ‘21 The telomerase enzyme catalytic cycle limits the telomerase enzymes’ ability to synthesize specific DNA segments of six nucleotides called repeats. These repeats, known as telomeres, are protective caps that prevent the destabilization of the genome by lengthening the ends of chromosomes. However, these protective caps shorten every time a cell divides.…
