In science, a surface wave is a type of mechanical wave that forms and travels along the boundary between two different media. Two commonly encountered surface waves are the waves observed on the ocean and the waves that shake the ground during an earthquake....
Water currents can be found in streams, rivers and oceans throughout the world. Water current is the rate of movement in the water, and ways to describe water current include its speed and direction. There are different types of water currents which behave in different ways because they are ...
Deep ocean currents in oceans are caused by a large amount of sinking surface water. Surface water is the upper layer of water closest to the top surface. The sun can easily reach this top layer, heat up the surface water and evaporate some of the water. When the surface water becomes e...
How do you know whether your recyclables are actually being recycled rather than being dumped at a landfill like this one in Canterbury, U.K.? See more landfill images. Peter Macdiarmid/Getty Images As the waste collectors cart your recyclables away, you’re suddenly hit by some terrible ...
Conclusion: Current admissions practices in the top North American pharmacy schools are varied and continue to rely on traditional components including GPA, PCAT, and interviews. However, there is also a movement toward using standardized and validated measures of non-cognitive aspects potentially more...
Epilepsy, one of the most common neurological diseases, affects more than 70 million people worldwide. Anti-seizure drugs targeting membrane ion channels or GABAergic neurotransmission are the first choices for controlling seizures, whereas the high inci
National Geographic photographer Brian Skerry has been diving in the Gulf of Maine for more than 40 years. After learning these waters were a harbinger of climate change, he set out to document the rapid shift and its ripple effects.
The tidal currents are constantly churning up the sediments that rivers deposit in the estuary. But a barrage would reduce the tidal currents. So a lot of that sediment would settle to the floor of the estuary. It wouldn't get stirred up so much. ...
To make computers faster and more efficient, scientists are using the brain as a model in this blossoming area of computer science. With the development of computer chips based on silicon and other semiconductor materials, we have witnessed a technological revolution over the last several decades. ...
I’ve noticed some reduction in under-eye swelling after just a few uses. For someone like me with sensitive skin, it’s been a game changer. The powerful combination of skin treatments — LED light, microcurrents, heat and massage — has felt soothing to my skin, all without any irritat...
