The Internet's Oldest .com, .net, and .org Domains

  The Internet's Oldest .com, .net, and .org Domains Have you ever wondered what the oldest registered domains on the internet are? Reddit has, and one user from Poland decided to find out and share exactly how he did it. Software and Network engineer Frederic Cambus has a website almost entirely devoted to his open source projects and has a particular love for OpenBSD. One of his most recent offerings was for those of us who, like him, are interested in DNS and internet history. As Cambus points out on his site, there is a Wikipedia page dedicated to the oldest extant registered domains online, but it isn't particularly thorough.

Australian researchers have uncovered the world ’ s oldest biological colour in the Sahara desert, in a find they said Tuesday helped explain why Scientists came across the samples accidentally when an oil company drilling in the Taoudeni basin in West Africa sent them rocks for analysis.

The pigment samples are around 1.1 billion years old, or around 15 times older than a Tyrannosaurus Rex© Provided by AFP The pigment samples are around 1.1 billion years old, or around 15 times older than a Tyrannosaurus Rex Australian researchers have uncovered the world's oldest biological colour in the Sahara desert, in a find they said Tuesday helped explain why complex lifeforms only recently emerged on earth.

The pink pigments were produced by simple microscopic organisms called cyanobacteria more than 1.1 billion years ago, some 500 million years older than previous colour pigment discoveries.

That makes the samples around "fifteen times older" than the Tyrannosaurus Rex dinosaur species, according to senior Australian National University researcher Jochen Brocks.

Scientists have discovered a new gene in your immune system and they want you to help name it

  Scientists have discovered a new gene in your immune system and they want you to help name it CSIRO scientists uncover a 500-million-year-old gene in the human genome that could lead to new treatments for cancer, influenza and autoimmune diseases. According to Dr Stewart and his colleagues, the gene probably evolved more than 500 million years ago in organisms much simpler than humans. "We found the gene by studying viruses," he said."Viruses can't replicate on their own, they need host genes in order to do that."So we performed a comprehensive screening looking through the entire genome to identify human molecules that are important for virus growth." require(["inlineoutstreamAd", "c.

Earth itself is about 4.5 billion years old and researchers said the latest find shed light on why more sophisticated plant and animal life only came into existence 600 million years ago.

Previous research argued that low oxygen levels in the atmosphere held back the evolution of complicated lifeforms, but the discovery of cyanobacteria at such an early date suggests that the organisms crowded out more plentiful food sources such as algae.

"Algae, although still microscopic, are a thousand times larger in volume than cyanobacteria, and are a much richer food source," Brocks told AFP.

"The cyanobacterial oceans started to vanish about 650 million years ago, when algae began to rapidly spread to provide the burst of energy needed for the evolution of complex ecosystems, where large animals, including humans, could thrive on Earth."

Scientists came across the samples accidently when an oil company drilling in the Taoudeni basin in West Africa sent them rocks for analysis.

The pigments are fossilised relics of chlorophyll, a chemical that allows plants and some microscopic lifeforms to turn light into energy.

Researchers said the pink pigment they discovered would have originally appeared blue-green to the human eye.

The findings were published Tuesday in the journal Proceedings of the National Academy of Sciences.

Earth's secret quadrillion tons of diamond found .
Scientists believe there could be more than a quadrillion tons of diamond scattered beneath the Earth's surface.The diamonds were found by analysing seismic records - essentially sound waves travelling through the Earth triggered by ground-shaking forces.
