Brain tumors may originate in a brain region distinct from where it becomes a lethal disease

by Children’s National Hospital A mouse model of glioblastoma, an aggressive type of cancer that can occur in the brain, suggests that this recalcitrant cancer originates from a pool of stem cells that can be a significant distance away from the resulting tumors. The findings of a new study, led by Children’s National Hospital researchers...

Non-invasive blood test can detect cancer four years before conventional diagnosis methods

by University of California – San Diego An international team of researchers has developed a non-invasive blood test that can detect whether an individual has one of five common types of cancers, four years before the condition can be diagnosed with current methods. The test detects stomach, esophageal, colorectal, lung and liver cancer. Called PanSeer,...

Study points to potential new approach to treating glaucoma and Alzheimer’s disease

by Bill Snyder, Vanderbilt University Medical Center Researchers at Vanderbilt University Medical Center (VUMC) have shown for the first time that when one optic nerve in the eye is damaged, as in glaucoma, the opposite optic nerve comes to the rescue by sharing its metabolic energy. In doing so, however, the undamaged optic nerve becomes...

Researchers identify a cancer metabolic pathway that could be a valuable target for therapy

by Sonia Fernandez, University of California – Santa Barbara Fighting cancer often means employing a suite of techniques to target the tumor and prevent it from growing and spreading to other parts of the body. It’s no small feat—the American Cancer Society predicts roughly 1.8 million new cases of cancer in the country in 2020,...

New system uses X-ray images of patients’ lungs to diagnose COVID-19

Reviewed by James Ives, M.Psych. (Editor) Researchers from the Department of Computer Architecture and Technology at the University of Seville’s School of Computer Engineering (ETSII) are working on a system that uses X-ray images of patients’ lungs to help diagnose COVID-19. This system uses deep learning to train a neural network model that can distinguish...

TEAM CREATES VESICLES WITHOUT ANY LIPIDS

Scientists have created hollow, spherical sacks called vesicles by using protein and RNA. These bubble-like entities—which form spontaneously when specific protein and RNA molecules mix in an aqueous buffer solution—hold potential as biological storage compartments. They could serve as an alternative to traditional vesicles that are made from water-insoluble organic compounds called lipids, researchers say....
