Foundational concept of ecology tested by experiment

An elementary school science activity asks children who have each been assigned a wetland plant or animal to connect themselves with string and tape to other "organisms" their assigned plant or animal interacts with in some ...

Making a light-harvesting antenna from scratch

(PhysOrg.com) -- Sometimes when people talk about solar energy, they tacitly assume that we're stuck with some version of the silicon solar cell and its technical and cost limitations. Not so.

First evidence of sleep in snails

Right/left handedness of snails changed in the lab

(PhysOrg.com) -- Like most animals, snails have either left- or right-handed asymmetry (chirality), both internally and externally, and the handedness is hereditary. A new study has for the first time found that handedness, ...

Pond

A pond is a body of standing water, either natural or man-made, that is usually smaller than a lake. A wide variety of man-made bodies of water are classified as ponds, including water gardens, water features and koi ponds; all designed for aesthetic ornamentation as landscape or architectural features, while fish ponds are designed for commercial fish breeding, and solar ponds designed to store thermal energy.

Standing bodies of water such as puddles, ponds, and lakes are distinguished from a water course, such as a brook, creek, or stream via current speed. While currents in streams are more easily observed, ponds and lakes possess thermally driven microcurrents and moderate wind-driven currents. These features distinguish a pond from many other aquatic terrain features, such as stream pools and tide pools.

Some mills use the kinetic energy of the moving water in the pond to generate electricity.
