Scientists Break the Genetic Code for Diabetes in Greenland

June 19, 2014 3:35 pm Videos Comments

A piece of detective work has mapped a special gene variant among Greenlanders that plays a particularly important role in the development of type 2 diabetes. The results can be used to improve prevention and treatment options for those genetically at-risk.

Sleep Quality and Duration Improve Cognition in Aging Populations

June 18, 2014 10:42 am Videos Comments

Maybe turning to sleep gadgets—wristbands, sound therapy and sleep-monitoring smartphone apps—is a good idea. A new University of Oregon-led study of middle-aged or older people who get six to nine hours of sleep a night think better than those sleeping fewer or more hours.

Scientists Take 'Tubular' Journey Through Brain Cells

June 16, 2014 2:38 pm Videos Comments

In a new study, scientists took a molecular-level journey into microtubules, the hollow cylinders inside brain cells that act as skeletons and internal highways. They watched how a protein called tubulin acetyltransferase (TAT) labels the inside of microtubules.

Researchers Discover New Form of Cancer

June 11, 2014 2:01 pm Videos Comments

By themselves, PAX3 and MAML3 don’t cause any problems. However, when they combine during an abnormal but recurring chromosomal mismatch, they can be dangerous. The result is a chimera—a gene that is half of each—and that causes biphenotypic sinonasal sarcoma. The tumor usually begins in the nose and may infiltrate the rest of the face, requiring disfiguring surgery to save the individual.

New Venture Aims to Understand, Heal Disrupted Brain Circuitry

May 27, 2014 1:57 pm Videos Comments

Scientists and physicians at UC San Francisco are leading a $26 million, multi-institutional research program in which they will employ advanced technology to characterize human brain networks and better understand and treat a range of common, debilitating psychiatric disorders.

Genes Link Circadian Clock to Eating Schedule

May 22, 2014 1:51 pm Videos Comments

Scientists have discovered a pair of genes that normally keeps eating schedules in sync with daily sleep rhythms, and, when mutated, may play a role in so-called night eating syndrome.

Scientists ID Potential Way to Halt Pancreatic Cancer Spread

May 21, 2014 12:49 pm Videos Comments

Scientists have shown how switching off a key protein in pancreatic cells slows the spread of the disease to other tissues, a key step which can mean patients have just weeks to live.

Engineer Invents Safe Way to Transfer Energy to Medical Chips in the Body

May 20, 2014 12:23 pm Videos Comments

A Stanford electrical engineer has invented a way to wirelessly transfer power deep inside the body and then use this power to run tiny electronic medical gadgets such as pacemakers, nerve stimulators or new sensors and devices yet to be developed.

Watching HIV Bud from Cells

May 19, 2014 2:15 pm Videos Comments

University of Utah researchers devised a way to watch newly forming AIDS virus particles emerging or “budding” from infected human cells without interfering with the process. The method shows a protein named ALIX gets involved during the final stages of virus replication, not earlier, as was believed previously.

Illuminating Neuron Activity in 3-D

May 19, 2014 1:37 pm Videos Comments

Researchers at MIT and the University of Vienna have created an imaging system that reveals neural activity throughout the brains of living animals. This technique, the first that can generate 3-D movies of entire brains at the millisecond timescale, could help scientists discover how neuronal networks process sensory information and generate behavior.

Research Leads to New Understanding of How Cells Grow, Shrink

May 16, 2014 1:19 pm Videos Comments

For a century, biologists have thought they understood how the gooey growth that occurs inside cells causes their protective outer walls to expand. Now, researchers have captured the visual evidence to prove the prevailing wisdom wrong.

The Promise of Personalized Medicine: An Apples-to-Apples Approach

May 16, 2014 12:18 pm Videos Comments

In our sixth video, Andrew Wiecek wraps up the discussion by taking a look at one of the therapeutic areas that could be significantly improved by personalized medicine: cancer. The approach is similar to comparing apples to apples, he says.

Where Have All the Mitochondria Gone?

May 15, 2014 11:16 am Videos Comments

It’s common knowledge that all organisms inherit their mitochondria—the cell’s “power plants”—from their mothers. But what happens to all the father’s mitochondria? How—and why—paternal mitochondria are prevented from getting passed on to their offspring after fertilization is still shrouded in mystery.

Measles Vaccine Can Kill Multiple Myeloma Cells

May 15, 2014 11:00 am Videos Comments

In a proof-of-principle clinical trial, researchers have demonstrated that virotherapy— destroying cancer with a virus that infects and kills cancer cells but spares normal tissues— can be effective against the deadly cancer multiple myeloma.

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.
