University of Maryland School of Medicine and University of Vermont researchers have shown how the brain communicates to blood vessels when in need of energy, and how these blood vessels respond by relaxing or constricting to direct blood flow to specific brain regions.
University of South Australia researchers have a bone to pick when it comes to drinking too much coffee as new research finds that excess caffeine may be linked to an increased risk of osteoporosis.

A Rutgers study has discovered that vitamin D regulates calcium in a section of the intestine that previously was thought not to have played a key role. The findings have important implications on how bowel disease, including ulcerative colitis and Crohn’s disease, may disrupt calcium regulation.
Scientists have long believed that ocean viruses always quickly kill algae, but Rutgers-led research shows they live in harmony with algae and viruses provide a “coup de grace” only when blooms of algae are already stressed and dying. The study, published in the journal Nature Communications, will likely change how scientists view viral infections of algae, also known as phytoplankton – especially the impact of viruses on ecosystem processes like algal bloom formation (and decline) and the cycling of carbon and other chemicals on Earth.
A new study finds women with diabetes and significant levels of calcium in their coronary arteries have higher rates of death from cardiovascular disease and all causes than their male counterparts.
