Scottish centipede Kampecaris recognized as the most ancient known arthropods

Researchers from the University of Texas at Austin found himself in the old world beetle (beetle, in this case, a collective term that collectively refers to insects, arachnids, crustaceans and other arthropods). Sample – the ancestor of the centipedes found on the island of Kerrera in Scotland, his age makes 425 million years.

Found fossil – an extinct species of millipedes Kampecaris obanensis. Although it was discovered in 1899, it is only now scientists were able to establish his exact age.

To do this, the team used the technology of radiometric Dating on zircon in the sediments. Zircon is a tiny, incredibly durable mineral pellets, so they experience all kinds of geological events that leave traces on them. This makes them perfect time capsules. So, the group examined the granules of zircon from three fossil localities in the UK, where, as you know, found some of the most early specimens of centipedes. Age Kampecaris was the oldest 425 million years, fossils from the second portion of Ludlow – 420 million years, and from Cowie – 414 million years.

Based on available data, the scientists hypothesize that the millipedes Kampecaris obanensis not only the most ancient found to date, millipedes, but some of the oldest arthropods in principle. To date, more ancient remains of this type on the Earth was not detected.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]
