Lowered brain cell growth may lead to poor sleep patterns in elderly, study shows

Poor sleep among the elderly may be a result of declining brain cell growth and development, according to UCLA researchers. Researchers in the lab of Noor Alam, an adjunct professor of medicine at UCLA and a research physiologist in the Veterans Affairs Greater Los Angeles Healthcare System, described how declining neural development may cause difficulty falling asleep or staying awake in aging individuals in a study published February.

UCLA study on worms lends insight into decision-making by people

Studying neural circuits in worms might give researchers insight into human decision-making, according to a paper published by UCLA researchers. Researchers in the lab of Elissa Hallem, a UCLA professor of microbiology, immunology and molecular genetics, published a study in January on how chemical signaling molecules affect how worms behave when they are hungry.

Researchers in molecular genetics lab discover pathway to cancer cell development

UCLA researchers discovered how to transform normal cells into cancer cells, allowing for the development of therapies against aggressive forms of cancer. In a study published Thursday, UCLA researchers in the lab of Owen Witte, professor in the Department of Microbiology, Immunology and Molecular Genetics, discovered how to manipulate the genes in normal prostate and lung cells to turn them into an aggressive form of cancer.
