Deciphering diabetes with ‘game-changing’ human blood vessels from stem cells

Institute of Molecular Biotechnology

Changes in blood vessels are the major cause of death and morbidity in diabetes. For the first time, sci-entists managed to grow perfect human blood vessels as organoids in a petri dish. This breakthrough engineering technology dramatically advances research of vascular dysfunction in diseases like diabetes, identifying a key pathway that prevents diabetic vasculopathy, as reported in the current issue of Nature.

Neutron science publications reach new highs at ORNL’s flagship facilities

Oak Ridge National Laboratory

The High Flux Isotope Reactor and the Spallation Neutron Source at the Department of Energy’s Oak Ridge National Laboratory have reached new levels of increased science productivity. In 2018, a record high of more than 500 scientific instrument publications were produced between HFIR and SNS—based on neutron beamline experiments conducted by more than 1,200 US and international researchers who used the world-leading facilities.

Born to Run: Just Not on Cocaine

Florida Atlantic University

A study finds a surprising response to cocaine in a novel strain of mutant mice – they failed to show hyperactivity seen in normal mice when given cocaine and didn’t run around. In other tests, they still found cocaine appealing, but displayed an inability to shake the memory of cocaine’s actions when the drug was no longer administered. The key change that blocks cocaine’s stimulant effects in these mice is serotonin, not dopamine, which is responsible for producing a high.

Bioactive Scaffolds Guide the Way to Sore Knee Relief, Cartilage Repair

National Institute of Biomedical Imaging and Bioengineering

NIBIB-funded researchers have developed a 3D-printed scaffold coated in aggrecan, a native cartilage component, to improve the regeneration of cartilage tissue in joints. The scaffold was combined with a common microfracture procedure and tested in rabbits. The University of Maryland researchers found the combination of the implant and microfracture procedure to be ten times more effective than microfracture alone.
