Targeted inhibition of ActRII pathway improves cardiac function in animal models of heart failure — ScienceDaily

A team led by Massachusetts General Hospital (MGH) investigators has found that activity of an important signaling pathway increases with aging and with heart failure. In their report published in Science Translational Medicine, they describe evidence from both humans and animal models that increased activin type II receptor (ActRII) activity correlates with worsening heart failure…

New technique has the potential to improve the quality and speed of imaging — ScienceDaily

Generating comprehensive molecular images of organs and tumors in living organisms can be performed at ultra-fast speed using a new deep learning approach to image reconstruction developed by researchers at Rensselaer Polytechnic Institute. The research team’s new technique has the potential to vastly improve the quality and speed of imaging in live subjects and was…

Elegant interplay of coloration strategies is discovered in squid’s smart skin — ScienceDaily

In the blink of an eye, the squid’s “smart skin” switches color and pattern for the purpose of camouflage or sexual signaling, a virtuosic display that has long fascinated scientists. Now, collaborators from Northeastern University and the Marine Biological Laboratory (MBL) report a paradigm-shifting discovery in how specialized organs in squid skin, called chromatophores, contribute…

Special diet with compounds contained in green tea and carrots restored working memory — ScienceDaily

A diet containing compounds found in green tea and carrots reversed Alzheimer’s-like symptoms in mice genetically programmed to develop the disease, USC researchers say. Researchers emphasize that the study, recently published in the Journal of Biological Chemistry, was in mice, and many mouse discoveries never translate into human treatments. Nevertheless, the findings lend credence to…
