The Hypogeum of Hal Saflieni and an unknown race with elongated skulls
Many ancient megalithic structures exist in Malta and one of them is the 'Hypogeum of Hal Saflieni', a subterranean structure with magnificent properties that is more than 5,000 years old.
Scientists Discover How Some Of The World’s First Animals Reproduced
Rangeomorphs, which lived about 565 million years ago, were pretty strange. They're often considered to be some of the first animals to evolve on Earth, but they share little in common with modern cri...

At 33, he's already being called the next Charles Darwin. Source: Rachel Tine for OZY A young MIT physicist may be close to figuring out the scientific origins of life. And he thinks God had a hand in...
New Evidence Emerges On The Origins Of Life On Earth
In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recen...
Chemistry Of Seabed's Hot Vents Could Explain Emergence Of Life
Hot vents on the seabed could have spontaneously produced the organic molecules necessary for life, according to new research by UCL chemists. The study shows how the surfaces of mineral particles ins...
How Structure Arose in the Primordial Soup
About 4 billion years ago, molecules began to make copies of themselves, an event that marked the beginning of life on Earth. A few hundred million years later, primitive organisms began to split into...
Organic molecules found circling nearby star
Astronomers have detected chemical precursors of building blocks of life in the large disk of dust and gas whirling around a young nearby star. These complex organic molecules, two forms of cyanide an...
Researchers may have solved origin-of-life conundrum
Now, researchers say they may have solved these paradoxes. Chemists report today that a pair of simple compounds, which would have been abundant on early Earth, can give rise to a network of simple re...
