Age, obesity, dopamine appear to influence preference for sweet foods

Age, obesity, dopamine appear to influence preference for sweet foods

As young people reach adulthood, preferences for sweet foods typically decline. But for people with obesity, research from the School of Medicine suggests that the drop-off may not be as steep and that the brain’s reward system operates differently in obese people than in thinner people. The findings are published in the journal Diabetes.
New insight into role of amyloid beta in Alzheimer’s disease

New insight into role of amyloid beta in Alzheimer’s disease

New Alzheimer’s disease research details a technique that speedily measures levels in the brain of a damaging protein fragment, and insight into why mutations in a specific gene increase the risk of developing the disease. Both studies, from researchers at Washington University School of Medicine in St. Louis, are available online in The Journal of Experimental Medicine.
Probing proteins’ 3-D structures suggests existing drugs may work for many cancers

Probing proteins’ 3-D structures suggests existing drugs may work for many cancers

Examining databases of proteins’ 3-D shapes, scientists at School of Medicine have identified more than 850 DNA mutations that appear to be linked to cancer. The information may expand the number of cancer patients who can benefit from existing drugs. The study, published June 13 in Nature Genetics, detailed a list of the mutations and associated drugs that may work against them.
New clues to understanding autoimmune diseases

New clues to understanding autoimmune diseases

With research that points to potential therapeutic targets for autoimmune diseases, researchers at Washington University School of Medicine in St. Louis have identified genetic master switches that turn up – or down – the activity of specific types of immune cells.
Gut microbes’ metabolite dampens proliferation of intestinal stem cells

Gut microbes’ metabolite dampens proliferation of intestinal stem cells

New research at Washington University School of Medicine in St. Louis indicates stem cells located in “pockets” in the intestine avoid contact with a prominent metabolite produced by beneficial microbes living in the gut. That metabolite – butyrate – restricts the proliferation of stem cells, potentially hampering the intestine from repairing itself after an injury or damage.
Development of gut microbes and gut immunity linked

Development of gut microbes and gut immunity linked

Studying twins from birth through age 2, scientists at Washington University School of Medicine in St. Louis have shown that the gut’s immune system develops in sync with the gut’s tens of trillions of microbes. The findings have implications for understanding healthy growth and, potentially, the origins of various immune disorders.
Turning humidity into clean drinking water

Turning humidity into clean drinking water

Social venture WOOTA (Water Out Of Thin Air) is the winner of this year’s School of Engineering & Applied Science’s annual Engineering Discovery Competition (EDC) and will receive $20,000 in cash, as well as $5,000 in legal services from Polsinelli for building a device that turns humidity in the air into clean drinking water.
