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.
Stem cell therapy can regenerate heart muscle in primates, according to a new study. The scientists on this and related projects are seeking way to repair hearts weakened by myocardial infarctions.
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.
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.
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.
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.
Researchers have discovered interacting proteins on the surface of the sperm and the egg essential to begin mammalian life. These proteins offer new paths towards improved fertility treatments and the development of new contraceptives.
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.
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.
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.
In a new study, researchers solved an age-old mystery of touch: how cells just beneath the skin surface enable us to feel fine details and textures.
Researchers have identified a genetic association with facial asymmetry in an ancient cavefish, a natural trait that may solve mysteries surrounding facial asymmetries in humans—conditions such as cleft palate or hemifacial microsomia.
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.
In our third video, Rob Fee is back to discuss how informatics can help to overcome one of the biggest challenges in personalized medicine: organizing and examining the mountains of data that are generated during the gene sequencing process. Rob's advice? Find a bioinformatician...fast!
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.
