Key player in cell metabolism identified

Jan 16 2018 - 00:01
Published in Nature Cell Biology (NCB), the study shows that the EXD2 protein is critical for the mitochondria, the cell's powerhouses, to produce energy. This protein was previously thought to be located in the cell nucleus and to be involved in DNA repair. The results contribute to our basic understanding of mitochondria and suggest that EXD2 could be important for fertility and represent a potential target for cancer therapy.

Genome architecture's surprising role in cell fate decisions

Jan 16 2018 - 00:01
New study led by researchers at the Centre for Genomic Regulation in Barcelona, shows unexpected and crucial role of genome architecture in determining cell fate. The work represents an important advance in our understanding of gene regulation and reveals a new layer of complexity that needs to be studied to properly interpret genomics and gene expression in the future. An example of how risky fundamental science with innovative approaches leads to surprising and important advances in knowledge.

Penn researchers identify new treatment target for melanoma

Jan 16 2018 - 00:01
Researchers in the Perelman School of Medicine at the University of Pennsylvania have identified a new therapeutic target for the treatment of melanoma. For decades, research has associated female sex and a history of previous pregnancy with better outcomes after a melanoma diagnosis. Now, a research team from Perelman School of Medicine at the University of Pennsylvania says it may have determined the reason for the melanoma-protective effect.

Insulating with microscopic bubbles

Jan 16 2018 - 00:01
Better thermal insulation means lower heating costs - but this should not be at the expense of exciting architecture. A new type of brick filled with aerogel could make thin and highly insulating walls possible in the future -- without any additional insulation layer.

Pediatric physician-scientists struggle for funding

Jan 16 2018 - 00:01
A new, multicenter study that included Washington University School of Medicine in St. Louis has found that most NIH grants awarded to researchers in pediatrics during the past five years have been limited to physicians in senior positions at a small number of institutions. The findings indicate an overall downward trend in funding for pediatric research, particularly among early-career physician-scientists.
