Study finds out similarity in function between healthy retina cell and tumor cell

How is a healthy retina cell like a tumor cell? It hijacks an energy-producing chemical reaction to churn out molecular building blocks. When tumor cells do it, they use the building blocks to make cancer grow and spread. But when retina cells do it, they renew photoreceptor membranes that keep our vision sharp.

Newly designed molecule could benefit people with Friedrich's Ataxia

Skin cells taken from patients with a rare genetic disorder are up to ten times more sensitive to damage from ultraviolet A radiation in laboratory tests, than those from a healthy population, according to new research from the University of Bath.

Dietary fiber helps to aggregate gut particles, study shows

Food, microbes, and medicine all clump together as they move through our gut. Sticky molecules secreted into our intestines bind the gut particles in the same way that flour holds a ball of dough together.

Reduced antibody adaptability may make the elderly more vulnerable to influenza

The influenza vaccine may be less effective in the elderly because their B cells are less capable of producing antibodies that can adapt to protect against new viral strains, researchers report February 19 in the journal Cell Host & Microbe.

Discovery of potent compound in native California shrub may lead to treatment for Alzheimer's

The medicinal powers of aspirin, digitalis, and the anti-malarial artemisinin all come from plants. A Salk Institute discovery of a potent neuroprotective and anti-inflammatory chemical in a native California shrub may lead to a treatment for Alzheimer's disease based on a compound found in nature.

Scientists demonstrate influence of food odors on proteostasis

The smell of food induces a variety of physiological processes in our body. Thus, the production of saliva and digestive enzymes is stimulated before the actual food intake in order to prepare the gastrointestinal tract for the upcoming digestive process.

Gene therapy restores hearing in mice with congenital genetic deafness

In collaboration with the universities of Miami, Columbia and San Francisco, scientists from the Institut Pasteur, Inserm, CNRS, Collège de France, Sorbonne University and the University of Clermont Auvergne have managed to restore hearing in an adult mouse model of DFNB9 deafness - a hearing disorder that represents one of the most frequent cases of congenital genetic deafness.

CRISPR technology creates pluripotent stem cells that are 'invisible' to the immune system

UC San Francisco scientists have used the CRISPR-Cas9 gene-editing system to create the first pluripotent stem cells that are functionally "invisible" to the immune system, a feat of biological engineering that, in laboratory studies, prevented rejection of stem cell transplants.
