Rice University-led team morphs nanotubes into tougher carbon for spacecraft, satellites
Experiments at Rice University showed nanodiamonds and other forms of carbon were created when carbon nanotube pellets were fired at a target at hypervelocity....
For first time, carbon nanotube transistors outperform silicon
The UW–Madison engineers use a solution process to deposit aligned arrays of carbon nanotubes onto 1 inch by 1 inch substrates. The researchers used...
Philae: Lost comet lander is found
Rosetta's lander Philae has been identified in OSIRIS narrow-angle camera images taken on 2 September 2016 from a distance of 2.7 km. The image...
Scientists discover how ‘super enzyme’ speeds up DNA repair
Scientists from the University of Sussex have discovered how an enzyme, known as PARP3, helps to accelerate the repair of DNA.
In the body, mutations can...
First gravitational waves form after 10 million years
This simulation shows how two galaxies merge over a period of 15 million years. The red and the blue dots illustrate the two black...
Brain circuit that drives sleep-wake states, sleep-preparation behavior is identified
Stanford University School of Medicine scientists have identified a brain circuit that's indispensable to the sleep-wake cycle. This same circuit is also a key...
Earth’s carbon points to planetary smashup
The ratio of volatile elements in Earth's mantle suggests that virtually all of the planet's life-giving carbon came from a collision with an embryonic...
NASA’s SDO Witnesses a Double Eclipse
You can tell Earth and the moon’s shadows apart by their edges: Earth’s is fuzzy, while the moon’s is sharp and distinct. This is...
