The "hand" and "foot" prints are 18m years older than the earliest, previously confirmed fossil remains of "tetrapods" or four-legged vertebrates and were left by lizard-like creatures up to 2.5 metres long. The discovery, reported in tomorrow's issue of the journal Nature, was made in a former quarry in the Holy Cross Mountains in south-eastern Poland. The fossil footprints can be reliably dated to the early Middle Devonian period, around 395 million years ago.
A new way capturing the energy from the Sun could increase the power generated by solar panels tenfold, a team of American scientists has shown. The new technique involves coating glass with a specific mixture of transparent dyes which redirect light to photovoltaic cells in the frame.
The technology, outlined in the journal Science, could be used to convert glass buildings into vast energy plants.
The technology could be in production within three years, the team said.

While government-sponsored, the Russian operating system will be based on Linux and will be open source. The initiative will be accompanied by significant infrastructural changes supporting information technology in education.
