Want to predict if your non-violent movement will succeed? Ask Isaac Newton
When Isaac Newton first attempted to describe momentum in his 1687 work Principia, he hit upon an eloquent formula—an object's momentum is its mass...
A single-photon source you can make with household bleach
Quantum computing and quantum cryptography are expected to give much higher capabilities than their classical counterparts. For example, the computation power in a quantum...
Scientists can now control thermal profiles at the nanoscale
At human scale, controlling temperature is a straightforward concept. Turtles sun themselves to keep warm. To cool a pie fresh from the oven, place...
Virtual ‘universe machine’ sheds light on galaxy evolution
How do galaxies such as our Milky Way come into existence? How do they grow and change over time? The science behind galaxy formation...
Researchers prove there are no water molecules between the ions in the selectivity filter...
Do potassium ions pass through the selectivity filter of a potassium channel alone, or are there water molecules between the ions, too? This question...
These sharks use unique molecules to glow green
In the depths of the sea, certain shark species transform the ocean's blue light into a bright green color that only other sharks can...
Nanowire arrays could improve solar cells
Transparent electrodes are a critical component of solar cells and electronic displays. To collect electricity in a solar cell or inject electricity for a...
Researchers discover oldest fossil forest in Asia
The Devonian period, which was 419 million to 359 million years ago, is best known for Tiktaalik, the lobe-finned fish that is often portrayed...
A key piece to understanding how quantum gravity affects low-energy physics
Researchers have, for the first time, identified the sufficient and necessary conditions that the low-energy limit of quantum gravity theories must satisfy to preserve...
Why humans in Africa fled to the mountains during the last ice age
People in Ethiopia did not live in low valleys during the last ice age. Instead they lived high up in the inhospitable Bale Mountains....
An 88 percent decline in large freshwater animals
Rivers and lakes cover just about one percent of Earth's surface, but are home to one third of all vertebrate species worldwide. At the...
