Researchers at UT Southwestern Medical Center at Dallas have discovered a protein that regulates growth and development of the heart from its fetal stage to adulthood.
Dr. Eric Olson and a team of researchers have discovered a protein that continuously regulates heart development in mice from the embryonic stage to adulthood.
Findings published in today’s edition of Cell report that the protein, named Homeodomain-Only Protein (HOP) by the researchers, is active in controlling heart growth at various stages of development in mice. Dr. Eric Olson, chairman of molecular biology at UT Southwestern and the study’s principal investigator, said the team set out to find proteins unique to the heart and study their functions. After they identified HOP, they bred mice that were genetically unable to produce the protein, with dramatic results.
"We created knockout mice lacking the gene to produce this protein, and they fell into two classes – they either died as embryos because their hearts didn’t grow, or they survived to adulthood with too many cardiac muscle cells," said Olson, director of the Nancy B. and Jake L. Hamon Center for Basic Research in Cancer and the Nearburg Family Center for Basic Research in Pediatric Oncology.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
