As early as age 13, the part of the human brain sought for learning and memory seems to stop producing cells, according to a new study.
So far, many scientists have estimated that in humans, the hippocampus region continues to produce hundreds of new neurons every day in the same way as other mammals.
Published by Nature, and conducted by American and Spanish researchers, the study is based on the analysis of samples from 59 brains of children and adults.
Scientists proposed a new classification of diabetes by considering that there are five different forms and not two as currently admitted, which they believe can refine the treatments.
To arrive at these five categories, the researchers examined the data of 13,720 patients since 2008, analyzing in particular their insulin production, their level of blood sugar or the age at which the disease appeared.
Goodyear continues its exploration of futuristic tire concepts with a model that incorporates natural foam for photosynthesis. The goal is twofold: clean the air by absorbing CO2 and producing energy.
This tire has a natural foam that absorbs moisture and CO2 to feed and releases oxygen through photosynthesis. The idea is to clean the air in these urban areas where polluting emissions are important. The manufacturer takes the example of Paris and its region which account for 2.5 million vehicles. If all were equipped with his tire, Goodyear estimates that it would absorb 4,000 tons of carbon dioxide and produce 3,000 tons of oxygen per year.
