Scientists build on case connecting inflammatory disease and depression

... For about 30 years, depression has been linked to low levels of serotonin, a brain chemical that regulates mood. Drugs called selective serotonin reuptake inhibitors (SSRIs) such as Prozac ease depression by elevating serotonin levels. "Although SSRIs can be used to treat immunotherapy-induced depress...

Researchers review evolutionary history of modern algae

...ern phytoplankton began to form at a time when the low oxygen conditions characterized much of the world's oceans. Since a cyanobacterium was capable of producing oxygen and nutrients, another bacterium, or a one-celled organism, ate the cyanobacterium, kept a part of the cyanobacterium undigested, and l...

Eventually, a shortage of nitrogen will curtail the plant's growth. "This explains why many plants are unable to sustain rapi...

As the isocaloric exchange between high and low protein diets was performed on carbohydrate, the flattening effect of the high protein diet on insulin and glucose basal levels could be attributed to its reduced carbohydrate content.
