Nitrogen is essential to marine life and cycles throughout the ocean in a delicately balanced system. Living organisms—especially marine plants called phytoplankton—require nitrogen in processes such as photosynthesis. In turn, phytoplankton growth takes up carbon dioxide from the atmosphere and helps regulate global climate.
Plants are responding in unexpected ways to increased carbon dioxide in the air, according to a twenty-year study conducted by researchers at the University of Minnesota and published in the journal Science. For the first 12 years, researchers found what they expected regarding how different types of grasses reacted to carbon dioxide. However, researchers’ findings took an unanticipated turn during the last eight years of the study.
A study of nearly half a million people has revealed that muscular strength, measured by handgrip, is an indication of how healthy our brains are.

Faster walking patients with heart disease are hospitalised less, according to research presented today at EuroPrevent 2018, a European Society of Cardiology congress, and published in the European Journal of Preventive Cardiology.
Spanish epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels. These statistical links do not indicate that there is a cause-effect relationship between soil type and cancer, but they suggest that the influence of metals from the earth's surface on the geographical distribution of tumors should be analyzed.
