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.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
