Scientists create renewable fossil fuel alternative using bacteria
The development is a step towards commercial production of a source of fuel that could one day provide an alternative to fossil fuels.
Single laser stops molecular tumbling motion instantly
In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now Northwestern University scientists have figured out an elegant way to stop a molecule from ...
Ride-sharing could cut cabs' road time by 30 percent
Cellphone apps that find users car rides in real time are exploding in popularity: The car-service company Uber was recently valued at $18 billion, and even as it faces legal wrangles, a number of companies ...
Engineers develop new sensor to detect tiny individual nanoparticles
Nanoparticles, engineered materials about a billionth of a meter in size, are around us every day. Although they are tiny, they can benefit human health, as in some innovative early cancer treatments, but ...
Coral organisms use minuscule appendages to control their environment, stirring up water eddies to bring nutrients
Conventional wisdom has long held that corals—whose calcium-carbonate skeletons form the foundation of coral reefs—are passive organisms that rely entirely on ocean currents to deliver dissolved substances, ...
Study claims cave art made by Neanderthals
A series of lines scratched into rock in a cave near the southwestern tip of Europe could be proof that Neanderthals were more intelligent and creative than previously thought.
Memory reformat planned for Opportunity Mars rover
(Phys.org) —An increasing frequency of computer resets on NASA's Mars Exploration Rover Opportunity has prompted the rover team to make plans to reformat the rover's flash memory.
Mixing in star-forming clouds explains why sibling stars look alike
The chemical uniformity of stars in the same cluster is the result of turbulent mixing in the clouds of gas where star formation occurs, according to a study by astrophysicists at the University of California, ...
Researchers suggest lack of published null result papers skews reliability of those that are published
