Knee Meniscus Regenerated with 3D-Printed Implant
Columbia University Medical Center researchers have devised a way to replace the knee’s protective lining, called the meniscus, using a personalized 3D-printed implant, or scaffold, infused with human growth factors that prompt the body to regenerate the lining on its own. The therapy, successfully tested in sheep, could provide the first effective and long-lasting repair of damaged menisci, which occur in millions of Americans each year and can lead to debilitating arthritis.

Drug Restores Hair Growth in Patients with Alopecia Areata
Seventy-five percent of patients with moderate to severe alopecia areata—an autoimmune disease that causes patchy and, less frequently, total hair loss—had significant hair regrowth after treatment with ruxolitinib, reported researchers from Columbia University Medical Center (CUMC). By the end of their treatment, average hair regrowth was 92 percent. Read more: http://newsroom.cumc.columbia.edu/blog/2016/09/22/drug-restores-hair-growth-in-patients-with-alopecia-areata/

A Skin Patch That Can Melt Fat
Researchers have devised a medicated skin patch that can turn energy-storing white fat into energy-burning brown fat locally while raising the body’s overall metabolism. The patch could be used to burn off pockets of unwanted fat such as “love handles” and treat metabolic disorders like obesity and diabetes, according to researchers at Columbia University Medical Center (CUMC) and the University of North Carolina.

New Lung “Organoids” In a Dish Mimic Features of Full-Size Lung
Researchers at Columbia University Medical Center have developed three-dimensional lung bud "organoids" from human pluripotent stem cells. The "mini organs" could be used to model lung diseases such as pulmonary fibrosis and respiratory syncytial virus infection. The research was carried out in the laboratory of Hans-Willem Snoeck, who is a professor of Medicine in Microbiology & Immunology at Columbia University Medical Center. The findings were published in Nature Cell Biology, and the paper can be accessed here: https://www.nature.com/ncb/journal/v19/n5/full/ncb3510.html

HGP-write: A Grand Challenge for Genome Engineering
Columbia University bioengineer Harris Wang explains the goals of the Human Genome Project - Write (HGP-write), an international initiative to develop new technologies for synthesizing very large genomes from scratch. Just as the original Human Genome Project (HGP-read) sparked a revolution in science and medicine, Dr. Wang says that HGP-write holds the potential to deliver new technologies that dramatically improve our understanding of how genomes actually work. These tools could help to address some of society’s major challenges, including energy sustainability, climate change, and the need for more effective ways of fighting disease. HGP-write is also promoting interdisciplinary dialogue concerning the ethical, legal, and social issues raised by genome engineering technologies.

Dietary Flavanols Reverse Age-Related Memory Decline
Dietary cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, according to a study led by Columbia University Medical Center (CUMC) scientists. The study, published today in the advance online issue of Nature Neuroscience, provides the first direct evidence that one component of age-related memory decline in humans is caused by changes in a specific region of the brain and that this form of memory decline can be improved by a dietary intervention.

Scientists Turn Tastes On and Off by Manipulating Brain Cells
Most people probably think that we perceive the five basic tastes—sweet, sour, salty, bitter and umami (savory)—with our tongue, which then sends signals to our brain “telling” us what we’ve tasted. However, scientists have turned this idea on its head, demonstrating in mice the ability to change the way something tastes by manipulating groups of cells in the brain.
