Far away solar objects, Oldest fossil found, Carbon nanotubes gaining on silicon.

  1. Search for 9th Planet reveals extremely distant objects

    Back in January the possibility of a 9th planet was announced and since then everyone has been looking for it, this has led to the discovery of several extremely distant solar system objects.

    Sciences believe that the newly discovered objects will help in the hunt for the 9th planet, but also help to improve out understanding of the solar system.

    Scott Sheppard, Carnegie Institution for Science, has said that “The smaller objects can lead us to the much bigger planet we think exists out there. The more we discover, the better we will be able to understand what is going on in the outer Solar System.”

  2. 3.7 billion-year-old fossil found in Greenland

    A team of researchers from the University of Wollongong, Australia have unearthed the oldest fossil in a remote area of Greenland.

    The fossil is a 3.7 billion-year-old stromatolite, the discovery has pushed back the fossil record nearly to the beginning of geological records, indicating that life on Earth formed very early on.

  3. Carbon nanotubes catch up to silicon

    Material engineers from the University of Wisconsin-Madison have created carbon nanotube transistors that outperform silicon transistors.

    Carbon nanotubes have to potential to open a world of high-performance, high-efficiency electronics, longer battery life, faster wireless communications and faster processing speeds. However, this was nothing more than a dream for the last 20 years.

    The team’s carbon nanotube transistors achieved current that is 1.9 times higher than state of the art transistors.
