Microchip-Like Technology Allows Single-Cell Analysis

May 14, 2014 1:12 pm Videos Comments

A U.S. and Korean research team has developed a chip-like device that could be scaled up to sort and store hundreds of thousands of individual living cells in a matter of minutes. The system is similar to a random access memory chip, but it moves cells rather than electrons.

Implanted Transistors Wrap Around Tissues

May 13, 2014 2:16 pm Videos Comments

Researchers from The University of Texas at Dallas and the University of Tokyo have created electronic devices that become soft when implanted inside the body and can deploy to grip 3-D objects, such as large tissues, nerves and blood vessels. These biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and stimulate the body for treatments.

Bone Marrow-on-a-chip Unveiled

May 6, 2014 12:16 pm Videos Comments

The latest organ-on-a-chip from Harvard's Wyss Institute for Biologically Inspired Engineering reproduces the structure, functions and cellular make-up of bone marrow, a complex tissue that until now could only be studied intact in living animals.

The Power of Personalized Medicine: It’s in the Stars

May 1, 2014 2:13 pm Videos Comments

This six-part video series from both Bioscience Technology and Drug Discovery & Development explains what personalized medicine is, how it works and the potential of this concept. In today's video, Rob Fee returns to discuss the power of genetic testing and preemptive medicine. But how do you learn if you carry risky genes, and most importantly, what do you do with that information?

Algae “See” a Wide Spectrum of Light

May 1, 2014 1:42 pm Videos Comments

Aquatic algae can sense an unexpectedly wide range of color, allowing them to sense and adapt to changing light conditions in lakes and oceans. Phytochromes are the eyes of a plant, allowing it to detect changes in the color, intensity, and quality of light so that the plant can react and adapt. Typically about 20 percent of a plant’s genes are regulated by phytochromes.

Scientists Create Circuit Board Modeled on the Human Brain

April 28, 2014 12:47 pm Videos Comments

Scientists have developed a new circuit board- dubbed the Neurogrid, consisting of 16 custom-designed "Neurocore" chips- modeled on the human brain, possibly opening up new frontiers in robotics and computing.

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.

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.
