We’ve combined lab-grown neurons with silicon chips and made it available to anyone, for first time ever.

Newly discovered brain cells count each bite before sending the order to cease eating a meal. Columbia scientists have found specialized neurons in the brains of mice that order the animals to stop eating.
Though many feeding circuits in the brain are known to play a role in monitoring food intake, the neurons in those circuits do not make the final decision to cease eating a meal.
The neurons identified by the Columbia scientists, a new element of these circuits, are located in the brainstem, the oldest part of the vertebrate brain. Their discovery could lead to new treatments for obesity.

A stressful life can leave marks on our genetic code, some of which can even be passed on to our children. A study now reveals how the biological impact of trauma on a mother persists long after the violent acts themselves have passed.
The international team of researchers demonstrate the physical mechanisms behind intergenerational trauma in humans, explaining why people with a family history of adversity are more prone to mental health conditions like anxiety and depression, despite not having experienced the adverse events themselves.
The researchers analyzed DNA collected from 48 Syrian families across three generations. These families included grandmothers or mothers who while pregnant had fled the 1982 siege and massacre in Hama or the 2011 armed uprising – both part of the ongoing Syrian civil war.
