Coaxing Hair Growth in Aging Hair Follicle Stem Cells

Just as people’s joints can get stiff as they age and make it harder for them to move around, hair follicle stem cells also get stiff, making it harder for them to grow hair, reports a new Northwestern Medicine study. But if the hair follicle’s stem cells are softened, they are more likely to produce […]

Tooth Decay Linked to Newly Identified Bacteria

Collaborating researchers from the University of Pennsylvania School of Dental Medicine and the Adams School of Dentistry and Gillings School of Global Public Health at the University of North Carolina have discovered that a bacterial species called Selenomonas sputigena can have a major role in causing tooth decay. Scientists have long considered another bacterial species, […]

The IL-17 Protein Plays a Key Role in Skin Aging

A team of scientists from the Institute for Research in Biomedicine (IRB Barcelona) in collaboration with the National Center for Genomic Analysis (CNAG) has discovered that IL-17 protein plays a central role in skin ageing. The study, which was led by Dr. Guiomar Solanas, Dr. Salvador Aznar Benitah, both at IRB Barcelona, and Dr. Holger […]

Gene Engineered Cell Therapy Developed to Target Brain Metastatic Melanomas

Acting as a team, twin stem cells activate the immune system to suppress tumor growth and prolong survival in representative preclinical models. Overall survival for patients with melanoma that has spread to the brain is only four to six months. Immunotherapies, which harness the power of the immune system to attack cancer cells, have garnered […]

DNA Damage Repaired by Antioxidant Enzymes

A typical human cell is metabolically active, roaring with chemical reactions that convert nutrients into energy and useful products that sustain life. These reactions also create reactive oxygen species, dangerous by-products like hydrogen peroxide which damage the building blocks of DNA in the same way oxygen and water corrode metal and form rust. Just how […]

New Class of Antibiotics to Fight Resistant Bacteria

Health professionals are in urgent need of new antibiotics to tackle resistant bacteria. Researchers at the University of Zurich and the company Spexis have now modified the chemical structure of naturally occurring peptides to develop antimicrobial molecules that bind to novel targets in the bacteria’s metabolism. Each year, more than five million people worldwide die […]

New Drug Delays Progression of Glioma

In an international study co-led by UCLA, scientists have shown that a new targeted therapy drug can extend the amount of time people with a subtype of glioma are on treatment without their cancer worsening. The finding suggests a possible new treatment option for people with the slow-growing but deadly brain tumor. The team found […]

Genetically Identical Lung Buds Could Accelerate the Study of Respiratory Diseases

Data from patient lung tissues greatly varies from person to person, obscuring the basic mechanisms of how, exactly, SARS-Co-V2 first infects lung cells. It’s also an after-the-fact analysis — as if we’re trying to map the route the virus took three states back. Turning down the noise of variability by studying genetically identical tissues from […]

Promising New Treatment for Tinnitus

Tinnitus, the ringing, buzzing or hissing sound of silence, varies from slightly annoying in some to utterly debilitating in others. Up to 15% of adults in the United States have tinnitus, where nearly 40% of sufferers have the condition chronically and actively seek relief. A recent study from researchers at the University of Michigan’s Kresge […]
