Information in Brain Cells' Electrical Activity Combines Memory, Environment, and State of Mind
July 17, 2013 — The information carried by the electrical activity of neurons is a mixture of stored memories, environmental circumstances, and current state of mind, scientists have found in a study of laboratory rats. The findings, which appear in the journal PLoS Biology, offer new insights into the neurobiological processes that give rise to knowledge and memory recall.Reclassification of Cannabis Linked to Cannabis Psychosis
July 18, 2013 — Researchers from the University of York have demonstrated that the change in cannabis declassification in 2009 has coincided with a significant increase in hospital admissions for cannabis psychosis - rather than the decrease it was intended to produce.A Risk Gene for Cannabis Psychosis

Palmilha de sapato carrega celular
Ao longo da história, foram desenvolvidos muitos dispositivos que convertem energia mecânica em elétrica. Lanternas que acendem depois que os usuários as sacodem ou giram uma manivela; ladrilhos na calçada que transformam os passos dos pedestres em eletricidade; turbinas eólicas convertem vento em eletricidade. E isso é só a ponta do iceberg.

Vitamin B: Choline Intake Improves Memory and Attention-Holding Capacity, Experts Say
July 11, 2013 — An experimental study in rats has shown that consuming choline, a vitamin B group nutrient found in foodstuffs like eggs and chicken or beef liver, soy and wheat germ, helps improve long-term memory and attention-holding capacity. The study, conducted by scientists at the University of Granada (Spain) Simón Bolívar University, (Venezuela) and the University of York (United Kingdom), has revealed that choline is directly involved in attention and memory processes and helps modulate them.Note to Teens: Just Breathe

Nova teoria tenta simplificar Matéria Escura
As galáxias giram tão rápido que se a única "cola" que as mantém coesas fosse a gravidade de toda a matéria que as compõe, elas se esfacelariam, arremessando suas estrelas, planetas e demais corpos celestes para o espaço.
