Squishing blood stem cells could facilitate harvest for transplants : How deformable cells are, and thus how stiff or squishy they are, plays an important role in retaining blood-forming stem cells in their marrow niches and thus preserving their long-term repopulation capabilities. https://www.sciencedaily.com/releases/2019/03/190322163344.htm

Tall ice-cliffs may trigger big calving events — and fast sea-level rise : Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving events. Although much calving occurs when …

Energy monitor can find electrical failures before they happen : A new system can monitor the behavior of all electric devices within a building, ship, or factory, determining which ones are in use at any given time and whether any are showing signs of an imminent failure. When tested on …

Paleontologists report world’s biggest Tyrannosaurus rex : Paleontologists have just reported the world’s biggest Tyrannosaurus rex and the largest dinosaur skeleton ever found in Canada. The 13-metre-long T. rex, nicknamed ‘Scotty,’ lived in prehistoric Saskatchewan 66 million years ago. https://www.sciencedaily.com/releases/2019/03/190322163331.htm

Ankle exoskeleton fits under clothes for potential broad adoption : The device does not require additional components such as batteries or actuators carried on the back or waist. https://www.sciencedaily.com/releases/2019/03/190322163322.htm

Developing new organic materials for electronics : A scientist has new ways of accelerating the development of new organic materials for electronics. The new approaches could have applications in other types of materials science research. https://www.sciencedaily.com/releases/2019/03/190322140522.htm

Chemicals induce dipoles to damp plasmons : A new study discovers a mechanism by which molecules affect the plasmonic response of gold nanorods. The mechanism could be used to enhance applications like catalysis that involve plasmon-driven chemistry. https://www.sciencedaily.com/releases/2019/03/190322140517.htm

Citizen science programs provide valuable data on intermittent rivers in southwestern US : An OU-led project is showing how citizen science programs provide valuable data on rivers in southwestern United States. The ecological and hydrological data obtained from intermittent rivers (rivers that dry at some point in space or time) in Arizona are …

Scientists argue for more comprehensive studies of Cascade volcanoes : Scientists argue for more ‘synthesis’ research looking at the big picture of volcanology to complement myriad research efforts looking at single volcanoes. https://www.sciencedaily.com/releases/2019/03/190322122544.htm
