Preparing for Pre-Board exams? Make sure you don't strain your eyes

A popular fitness trend among young people may be quietly undermining their sleep. A new study led by researchers at the University of Toronto has found that teenagers and young adults who use pre-workout supplements are significantly more likely to experience extremely short sleep durations.

A first-of-its-kind trial is testing adult stem cell transplants for advanced dry macular degeneration. Early results show the treatment is safe and can significantly improve vision, even in severely affected patients.

A novel, error-corrected technique for identifying cancer from blood samples is significantly more sensitive and accurate than previous methods and could be helpful for monitoring patients' disease status following treatment, according to a study by Weill Cornell Medicine and New York Genome Center investigators.

Researchers have developed eye drops that extend vision in animal models of a group of inherited diseases that lead to progressive vision loss in humans, known as retinitis pigmentosa.

Researchers have discovered a fundamental mechanism that affects pupil size: breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation, which could affect vision.

Researchers at the University of Colorado Anschutz Medical Campus found a promising therapeutic candidate that could aid in the restoration of vision in those suffering from multiple sclerosis (MS) and other neurodegenerative diseases.

A research team at the University of Arizona College of Medicine--Tucson's Sarver Heart Center found that a subset of artificial heart patients can regenerate heart muscle, which opens the possibilities of new ways to treat and perhaps someday cure heart failure.

Researchers at Emory University's Winship Cancer Institute discovered a new form of immune cell known as the stem-like CD4 T cell, which plays an important role in anti-tumor immunity. The pre-clinical findings, published in Nature, indicate the potential for activating these cells to combat tumours more effectively, providing new hope for broader treatment success, particularly in patients with cancer that are unresponsive to conventional immunotherapies.

Researchers in Michael Sigal's lab at the Max Delbruck Center and Charite - Universitatsmedizin Berlin have discovered the significance of the p53 gene in ulcerative colitis. The work, published in Science Advances, proposes a potential new therapeutic target for preventing illness progression to cancer.

Researchers from the University of Auckland, Amsterdam University Medical Center, and Cambridge University Hospitals have successfully treated over ten patients with CRISPR/Cas9 technology, with preliminary findings just published in a leading journal.
