Brain Size Matters in Animal Self-control

April 22, 2014 2:47 pm Videos Comments

Scientists collaborated on the first large-scale investigation into the evolution of self-control in animals, defined in the study as the ability to inhibit powerful but ultimately counter-productive behavior.

'Molecular Tweezer' is a Step Toward Parkinson’s Treatment

April 21, 2014 2:43 pm Videos Comments

The most effective way to tackle debilitating diseases is to punch them at the start and keep them from growing. Research shows that a small “molecular tweezer” keeps proteins from clumping, the first step of disorders such as Parkinson’s disease, Alzheimer’s disease and Huntington’s disease.

A Cinderella Story: Stem Cells in Personalized Medicine

April 17, 2014 1:17 pm Videos Comments

In part four of our video series, Andrew Wiecek is back to discuss the role that induced pluripotent stem (iPS) cells play in personalized medicine. How do they help? Well, iPS cells are kind of like Cinderella's glass slipper.

Brain Activity May Mark the Beginning of Memories

April 14, 2014 2:30 pm Videos Comments

By tracking brain activity when an animal stops to look around its environment, neuroscientists at Johns Hopkins University believe they can mark the birth of a memory. Using lab rats on a circular track, a team of brain scientists, noticed that the rats frequently paused to inspect their environment with head movements as they ran.

How the Brain Pays Attention

April 11, 2014 1:46 pm Videos Comments

Picking out a face in the crowd is a complicated task: Your brain has to retrieve the memory of the face you’re seeking, then hold it in place while scanning the crowd, paying special attention to finding a match. A new study reveals how the brain achieves this type of focused attention on faces or other objects.

Potential Link Between Brain Development and Breast Cancer Gene

April 9, 2014 2:09 pm Videos Comments

Scientists at the Salk Institute have uncovered details into a surprising—and crucial—link between brain development and a gene whose mutation is tied to breast and ovarian cancer. Aside from better understanding neurological damage associated in a small percentage of people susceptible to breast cancers, the new work also helps to better understand the evolution of the brain.

Nanoparticles Cause Cancer to Self-destruct

April 3, 2014 1:59 pm Videos Comments

Using magnetically controlled nanoparticles to force tumor cells to ‘self-destruct’ sounds like science fiction, but could be a future part of cancer treatment, according to research from Lund University in Sweden. The new technique is much more targeted than trying to kill cancer cells with techniques such as chemotherapy.

Researcher Invents ‘Mini Heart’ to Help Return Venous Blood

March 27, 2014 2:16 pm Videos Comments

George Washington University researcher Narine Sarvazyan, PhD, has invented a new organ to help return blood flow from veins lacking functional valves. A rhythmically contracting cuff made of cardiac muscle cells surrounds the vein acting as a 'mini heart' to aid blood flow through venous segments. The cuff can be made of a patient’s own adult stem cells, eliminating the chance of implant rejection.
