The detection of physical forces is one of the most complex challenges facing science. Although Newton's apple has long solved the problem of gravity, imaging the physical forces that act in living ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

A former NASA engineer working on a propellant-less propulsion drive has claimed that the device can deliver enough thrust to achieve lift in Earth's gravity, an effect which should not take place ...

Dark matter makes up 27 percent of the universe’s total mass and energy — nearly five times more than “normal” matter that comprises planets and stars. True to its name, dark matter is hard to ...

Epithelial tissues are in constant interaction with their environment. Maintaining their functionality requires dynamic balance (homeostasis) and that their cell numbers are tightly regulated. This is ...

There may be a fifth fundamental force of the universe that we haven't documented yet — and, according to new research, our best bet of uncovering it may not lie in deep space, but in objects ...

A chameleon-like force that shifts its nature based on its environment could explain a major physics quandary: how the mysterious substance called dark energy is compelling the cosmos to expand faster ...

Scientists have detected a strange new type of high-frequency wave on the sun's surface, and the waves are moving three times faster than scientists thought was possible. Scientists can't see into the ...
