Brain Mechanism for Common Age-Related Memory Loss Pinpointed
Neuroscientists have pinpointed a mechanism in the brain responsible for a common type of age-related memory loss.
Islet Cell Transplants Shown To Be Safe and Reliable for Diabetic Patients
The team behind the largest islet transplant program in the world has reported that the procedure is a safe, reliable and life-changing treatment for people with hard-to-control diabetes.
T Cell Creates Two Genetically Identical, but Functionally Different, Daughter Cells
Researchers have explained how a CD8+ T cell can have two functionally distinct daughter cells after it divides, despite the cells being genetically identical.
Protein Complex Plays Key Role in DNA Loop Formation
Researchers discovered that the MCM complex plays an important role in restricting DNA loop formation and thus in the three-dimensional structure of the genome and in gene regulation.
Heart Disease May Be Worsened by Aggressive T Cells
T cells that attack apolipoprotein B, the main component of "bad" cholesterol, could be contributing to inflammation that worsens heart disease.
Drug Compound Targets Signaling Regulator and Reduces Anxiety-Like Behavior in Mice
Researchers have developed a brain-permeable compound (25-106) that targets a signaling regulator in brain neurons. The team notes that when the new compound was administered to mice, it could alter their neurobehavior and reduce anxiety-like behavior.
Shift in Cholesterol Metabolism Triggers “Death Spiral” in Maternal Octopuses
A new study by researchers from the University of Chicago, the University of Washington, and the University of Illinois Chicago (UIC) shows that the optic gland in maternal octopuses undergoes a massive shift in cholesterol metabolism, resulting in dramatic changes in the steroid hormones produced.
Stem Cell Therapy Engineered To Treat Aggressive Brain Cancer
Investigators at Brigham and Women’s Hospital and Harvard Medical School have devised a novel therapeutic method using stem cells taken from healthy donors to treat glioblastomas post-surgery by attacking glioblastoma-specific tumor cells.
Male Pheromones Improve the Health of Females' Egg Cells
A study in C. elegans has shown that exposure to male pheromones slows down the rate of aging in female egg cells, resulting in healthier offspring.
Intricacies of X Chromosome Inactivation Revealed
Two new studies reveal more about the X chromosome silencing process and provide insights that could improve stem cell research.
