DNA analysis of bat droppings shows astonishingly high number of insect species

Adequate food supply is a fundamental need and requirement for survival. To protect a species, it is often very helpful to know what that species prefers and frequently consumes. Through the analysis of DNA traces in the droppings of a Leisler's bat colony, researchers at LIB (Le … | Continue reading

Physicists 'entangle' individual molecules for the first time, hastening possibilities for quantum computing

For the first time, a team of Princeton physicists have been able to link together individual molecules into special states that are quantum mechanically "entangled." In these bizarre states, the molecules remain correlated with each other—and can interact simultaneously—even if … | Continue reading

New dark matter theory explains two puzzles in astrophysics

Thought to make up 85% of matter in the universe, dark matter is nonluminous and its nature is not well understood. While normal matter absorbs, reflects, and emits light, dark matter cannot be seen directly, making it harder to detect. A theory called "self-interacting dark matt … | Continue reading
