Que o plástico é um problema ambiental seríssimo, todos sabemos. Mas suas complicações vão além da poluição e já temos até pesquisas sobre o material estar dentro do nosso corpo. Em uma pesquisa da Universidade Federal de Minas Gerais, a UFMG, cientistas buscavam formas sustentáveis para substituir o plástico e acabaram desenvolvendo uma espuma capaz de reconhecer e absorver herbicidas dos alimentos e da água.
Artificial sweeteners are one of diet soda’s main ingredients. But studies have shown that the artificial sweeteners within diet sodas can cause a series of health problems. We decided to take a look at what happens to the body when you only drink diet soda. Following is a transcript of the video.

Lots of factors affect whether and what students learn in school, but most often that conversation gets boiled down into a single letter grade, a symbol of everything a student knows or doesn’t know. Because grades are often required, and easy to understand, they have become the focus for many parents, teachers and students.

This complicated dynamic means that grading policies are at the center of discussions around how to change teaching and learning.
Groundbreaking research shows that neurological health depends as much on signals sent by the body’s large, leg muscles to the brain as it does on directives from the brain to the muscles. Published today in Frontiers in Neuroscience, the study fundamentally alters brain and nervous system medicine — giving doctors new clues as to why patients with motor neuron disease, multiple sclerosis, spinal muscular atrophy and other neurological diseases often rapidly decline when their movement becomes limited.
La asociación ambientalista Environmental Working Group analizó 45 de los cereales más consumidos en Estados Unidos, en su mayoría hechos con avena, y determinó que 43 de ellos tienen rastros de un herbicida cancerígeno.
