Breakthrough harnesses light for controlled chemical reaction

Breakthrough harnesses light for controlled chemical reaction

When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants “learned” to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit more recently. But this week, in the journal Science , he and three collaborators detail a way to use sunlight and two catalysts to create molecules that are difficult to make with conventional techniques Continue reading

Why does breast cancer often spread to the lung? Experts explain

Why does breast cancer often spread to the lung? Experts explain

New research led by Alison Allan, PhD, a scientist at Western University and the Lawson Health Research Institute, shows why breast cancer often spreads or metastasizes to the lung. Breast cancer is the number one diagnosed cancer and the number two cause of cancer-related deaths among women in North America Continue reading

Skin layer grown from human stem cells could replace animals in drug, cosmetics testing

Skin layer grown from human stem cells could replace animals in drug, cosmetics testing

An international team led by King’s College London and the San Francisco Veteran Affairs Medical Center (SFVAMC) has developed the first lab-grown epidermis — the outermost skin layer — with a functional permeability barrier akin to real skin. The new epidermis, grown from human pluripotent stem cells, offers a cost-effective alternative lab model for testing drugs and cosmetics, and could also help to develop new therapies for rare and common skin disorders. The epidermis, the outermost layer of human skin, forms a protective interface between the body and its external environment, preventing water from escaping and microbes and toxins from entering.

Large-scale identification, analysis of suppressive drug interactions

Large-scale identification, analysis of suppressive drug interactions

Baker’s yeast is giving scientists a better understanding of drug interactions, which are a major cause of hospitalization and illness world-wide. When two or more medications are taken at the same time, one can suppress or enhance the effectiveness of the other. Similarly, one drug may magnify the toxicity of another. Continue reading

Blood cells reprogrammed into blood stem cells in mice

Blood cells reprogrammed into blood stem cells in mice

Researchers at Boston Children’s Hospital have reprogrammed mature blood cells from mice into blood-forming hematopoietic stem cells (HSCs), using a cocktail of eight genetic switches called transcription factors. Continue reading
