The world’s oldest known fossilized skin belonged to a species of reptile that lived before dinosaurs roamed the Earth, a new study has found.

The fragment of fossilized reptile skin was found in a limestone cave in Oklahoma, United States, and is at least 130 million years older than the oldest previously known skin fossil.

Researchers from the University of Toronto Mississauga identified a skin fragment with a pebbled surface which is similar to crocodile skin, according to a press release published Thursday.

Spanish colonizers enslaved the Lucayans, putting an end to their lineage by 1530.

New #openaccess article online: A diamond #Nanophotonic interface with an optically accessible deterministic electronuclear spin register.

By implanting 117Sn, a fibre-packaged nanophotonic diamond waveguide with optically addressable hyperfine transitions separated by 452 MHz is demonstrated. This enables the formation of a spin-gated optical switch and achieving a waveguide-to-fibre extraction efficiency of 57%.

A scalable synthetic fiber that mimics the structure of polar bear fur has excellent thermal and mechanical properties.

Shares of Amazon closed up 1.5% on Wednesday.

Last November, the European Commission warned the planned acquisition raises competition concerns, saying it found Amazon may have the ability to prevent or degrade iRobot rivals’ access to its online site by delisting or reducing the visibility of their products in search results and other areas.

The European Commission opened an in-depth probe into the purchase last July and is expected to rule on the deal by Feb. 14.

The North Korean dictator was also quoted as saying he had ‘no intention of avoiding war’ with his country’s southern neighbor as he toured the major weapons factory, cigarette in hand.

I cannot completely confirm if this true as the nuclear threats are a constant thing now.

Locally correctable codes need barely any information to fix errors, but they’re extremely long. Now we know that the simplest versions can’t get any shorter.
