Researchers show the insights drones can provide by monitoring corn on small farms‎

With already thin profit margins and increasingly uncertain farm labor and other input costs, precision agriculture technology could improve New England's small and medium-sized farms' efficiency, productivity, and resilience. Unfortunately, factors such as up-front costs and validation of the technology's accuracy in the region remain a barrier to adoption.

Study finds fisheries management—not predator recovery—drives catch levels in the North Sea‎

A new research study found that well-managed fisheries can support the recovery of large marine predators such as seals and porpoises, showing that conservation and sustainable seafood production can go hand in hand. While the impacts of protected species are often debated, the study led by researchers at University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science's Cooperative Institute for Marine and Atmospheric Studies (CIMAS), showed that fishing effort—not predator recovery—is the main driver of fishery yields in the North Sea.

Discovery of PITTs shows platelets can switch from clotting to driving vessel inflammation‎

A team from Würzburg has fundamentally changed our understanding of platelet biology. The researchers demonstrate that the surface protein integrin αIIbβ3 is not only a key molecule in blood clotting, but can also act as a pro-inflammatory effector during severe disease processes. Under these conditions, αIIbβ3 switches function and becomes a structural component of a previously unknown organelle: PITT (platelet-derived integrin- and tetraspanin-rich tether).

Whales may divide resources to co-exist under pressures from climate change‎

The North Atlantic Ocean is warming up. Higher temperatures and increased human activity in the region can trigger abrupt changes in marine ecosystems, for example, how species are distributed and what they eat.
