A new study has presented and characterized the formation and properties of a superparamagnetic ring, which fits snugly around a drop of water due to liquid-liquid interaction, and allows the drops to...
Our everyday lives rely on planned movement through the environment to achieve goals. A new study by MIT neuroscientists at the Picower Institute for Learning and Memory at MIT identifies a well-conne...
Common sense might dictate that for an object to move from one point to another, it must go through all the points on the path.“Imagine someone driving from Kansas City to Topeka on I-70 — it’s safe t...
Animals move in diverse ways, from short foraging trips to seasonal trans-continental migrations, but common to all is that selection favours efficiency and prudent usage of energy, time and risk. The...
A new way to use the chemical reactions of certain enzymes to trigger self-powered mechanical movement has been developed by a team of researchers at Penn State University and the University of Pittsb...
Automated procedures for photogrammetric image processing and Digital Elevation Models (DEM) extraction yield high precision terrain models in a short time, reducing manual editing; their accuracy is...
The objective of the STRATAFORM program of the Office of Naval Research (ONR) is to understand how the stratigraphy of continental shelves and continental slopes is created and preserved by the proces...
We are unique. Although all species affect their environments, Homo sapiens affects more of our planet in more ways to a greater degree than any other species, past or present. But we are also unique ...
The National Oceanographic Partnership Program (NOPP) was legislatively established in 1997 in Public Law 104-201 to promote a number of national goals through improved knowledge of the oceans and to ...
Rock glaciers are striking phenomena of high mountain permafrost. These periglacial landforms are composed of rock and ice and creep downslope at a typical rate of a few decimeters per year. This mo...
The population of beluga whales in Cook Inlet, Alaska, is in decline, and since 2000 these whales have been under consideration for designation as "endangered" under the Endangered Species Act (and we...
Rizzi (1989), developing a proposal first made in Rizzi (1988) and incorporating an important modification from Cinque (1989), argues that whether wh- expressions can undergo so-called ``long'' moveme...
Water and contaminants moving through the vadose zone are often subject to a large number of simultaneous physical and chemical nonequilibrium processes. Traditional modeling tools for describing flow...
Microtubules are required for several cellular processes including vesicle transport, cytoplasmic organization, cell motility, maintenance of cellular polarity, and mitosis. The mechanisms by which mi...
Understanding the movement phenology of the four-toed salamander (Hemidactylium scutatum) is essential to guide management practices. I examined the relationship between environmental variables and th...
