MIT Scientists Demonstrate Memories Reside In Neurons

Neuroscientists — scientists who study the brain — have long attempted to understand the nature of memory. Engrams, or complete memories that are encoded in the brain, now appear to be stored physically as opposed to conceptually, according to research published in the journal Nature [1].

New Warning for Statins

Statins, including Pfizer Inc.’s Lipitor, are among the most prescribed drug in the world, and are currently routinely taken by millions of Americans. They are indicated for people with high blood pressure and/or high cholesterol, and have been shown to significantly reduce the risk of heart disease, heart attack, and stroke in this population. Yet the FDA has just issued new warnings concerning potential side effects: elevated blood sugar, which is a risk factor for developing type 2 diabetes, and cognitive impairment such as memory loss. The warnings will not be affixed to the outside of the bottle, but will be included in the package insert that comes with all prescription medications.

Amid Debate, First Proton Therapy Center Opens in New Jersey

All too often, the most brutal part of a bout with cancer is radiation therapy. X rays are electromagnetic waves that travel with a constant amount of energy, so although they effectively kill cancer cells, they pass through the skin and healthy tissues on their way to and from the tumor. In doing so, they damage the normal cells in their path. Protons, on the other hand, are particles that have a mass and a charge (they are positive). They can thus be targeted with exquisite specificity only to the tumor site, emitting the bulk of their radiation there and there only and sparing patients the terrible side effects that can accompany therapy with X rays.
