Culturally sensitive conservation approaches needed to protect Ethiopian church forests — ScienceDaily

Human disturbance reduces forest density, biomass, and richness of species in sacred church forests of northern Ethiopia, according to new research by Catherine L. Cardelús of Colgate University in Hamilton, NY, and colleagues. These findings appear in PLOS ONE. Due to land-use changes, such as roads and agriculture, forested area that once covered much of…

Alternative to anti-inflammatory therapies reduces IBD symptoms in mice — ScienceDaily

People with inflammatory bowel disease (IBD) live with frequent, miserable episodes of abdominal pain, diarrhea and in severe cases, rectal bleeding. Standard treatments are aimed at directly suppressing inflammation, but many patients find little relief from such an approach. Now, researchers at Washington University School of Medicine in St. Louis have found a compound that…

New insights into the geographical landscape of prehistoric central Tibet — ScienceDaily

A team of scientists from the UK and China have uncovered new evidence, using recently-discovered 25-million-year-old fossilised palm leaves, that Tibet’s geography was not as ‘high and dry’ as previously thought. The new research, co-authored by academics from the University of Bristol’s School of Geographical Sciences, suggests that central Tibet must have been no higher…

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…
