  • Low Consumption of Vitamin K by Adolescents Associated with Unhealthy Enlargement of the Heart's Major Pumping Chamber

    Scientists have found another reason for children to eat their green leafy vegetables.

  • Irish Scientists Discover Method to Produce Electricity from Tears

    A team of scientists at University of Limerick has discovered that applying pressure to a protein found in egg whites and tears can generate electricity. The researchers from the Bernal Institute observed that crystals of lysozyme, a model protein that is abundant in egg whites of birds as well as in the tears, saliva and milk of mammals can generate electricity when pressed. Their report was published on October 2 in the journal, Applied Physics Letters.

  • Puerto Rico facing disaster of major proportions

    A week after Hurricane Maria rolled through Puerto Rico, the island faces a public health crisis with no power and a growing shortage of drinking water and food.

  • Bone Marrow Protein May Be Target for Improving Stem Cell Transplants

    Bone marrow contains hematopoetic stem cells, the precursors to every blood cell type. These cells spring into action following bone marrow transplants, bone marrow injury and during systemic infection, creating new blood cells, including immune cells, in a process known as hematopoiesis.

  • Peak contamination levels from Fukushima off North America now known

    For the first time since 2011, peak contamination levels in Pacific Canadian waters from Japan’s Fukushima Daiichi nuclear disaster are known, says a University of Victoria scientist who has been monitoring levels since the meltdown of three reactors at the plant.

  • How healthy is the Canadian health-care system?

    Canada’s health-care system is a point of Canadian pride. We hold it up as a defining national characteristic and an example of what makes us different from Americans. The system has been supported in its current form, more or less, by parties of all political stripes — for nearly 50 years.

  • Model predicts performance of glucose-responsive insulin

    People with Type 1 diabetes must check their blood glucose several times a day and inject themselves with insulin to keep their blood sugar levels within a healthy range. A better alternative, long sought by diabetes researchers, would be insulin that is engineered to linger in the bloodstream, becoming active only when needed, such as right after a meal.

  • Disease Resistance Successfully Spread from Modified to Wild Mosquitoes

    Using genetically modified (GM) mosquitoes to reduce or prevent the spread of infectious diseases is a new but rapidly expanding field of investigation. Among the challenges researchers face is ensuring that GM mosquitoes can compete and mate with their wild counterparts so the desired modification is preserved and spread in the wild population. Investigators at Johns Hopkins University have engineered GM mosquitoes to have an altered microbiota that suppresses human malaria-causing parasites. These GM mosquitos preferred to mate with wild mosquitoes and passed along the desired protection to many generations of offspring.

  • To Improve Melanoma Treatment, Researchers Look to Block Deletion of 'Self-Reactive' Immune Cells

    Researchers at the University of North Carolina Lineberger Comprehensive Cancer Center are using what they know about a rare, inherited autoimmune disease to turn the body’s defenses against melanoma.

  • Smart Molecules Trigger White Blood Cells to Become Better Cancer-Eating Machines

    A team of researchers has engineered smart protein molecules that can reprogram white blood cells to ignore a self-defense signaling mechanism that cancer cells use to survive and spread in the body. Researchers say the advance could lead to a new method of re-engineering immune cells to fight cancer and infectious diseases. The team successfully tested this method in a live cell culture system.
