Killer Saver!! -- Eco-friendly aquatic predators

This freshwater stickleback can keep in check the tiny animals in stream water that graze on plants and algae. n ecosystems around the world, big guys eat littler guys, who in turn eat plants and other organisms at the base of the food web. A study now finds that removing top predators in freshwater environments allows their prey to flourish and overgraze on plants and algae. The result of the missing plant matter: a 90 percent reduction in uptake and storage of carbon dioxide. Several research teams have explored the importance of predators in protecting organisms that store carbon, notes ecologist James Estes of the University of California, Santa Cruz, who was not involved in the new research. The new study is particularly strong, he says, because it demonstrates predators' influence across a broad range of ecosystems. It therefore suggests “that the phenomenon may be fairly general.” When pesticide runoff, overfishing or other human activities impact ecosyste

What are asteroids, meteors ... গ্রহাণু, উল্কা কি

A meteor streaks across the sky in eastern Russia in this picture released by the Russian Emergency Ministry. The terms asteroid, meteor, meteorite and meteoroid get tossed around recklessly, especially when two of them threaten the Earth on the same day. Here's a quick explainer: An asteroid is a rocky object in space that's smaller than a planet they're sometimes called minor planets or planetoids, according to NASA. Other sources refer to them loosely as "space debris," or leftover fragments from the formation of the solar system (like the extra pieces that remain after constructing a build-it-yourself bookcase from IKEA). There are millions of asteroids orbiting the sun, some 750,000 of which are found in the asteroid belt, a vast ring of asteroids located between the orbits of Mars and Jupiter. Asteroids can be as large as hundreds of kilometers wide: The asteroid Ceres, sometimes referred to as a dwarf planet, is 940 km (584 miles) wide.
