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.
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.
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.
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.
Investigators report that a gene essential for normal brain development, and previously linked to Autism Spectrum Disorders, also plays a critical role in addiction-related behaviors.
A scientific team has discovered that a common form of a gene already associated with long life also improves learning and memory, a finding that could have implications for treating age-related diseases like Alzheimer’s.
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.
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?
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.
