Geological detectives are piecing together an intriguing seafloor puzzle. The Indian Ocean and some of its islands, scientists say, may lie on top of the remains of an ancient continent pulled apart by plate tectonics between 50 million and 100 million years ago.

The earth’s surface is not fixed. Oceans come and go and continents are constantly moving, breaking up and reforming like blobs of oil on the surface of a stock-pot.

A temple believed to be about 5,000 years old has been discovered at the ancient El Paraiso archaeological site in a valley just north of Lima in Peru.

What if I told you that there's a mathematical formula buried deep in living things that tells us — all of us, dandelions, gorillas, sea grasses, elm trees, buttercups — when it's time to die. Scientists think there is such rule.

Engraved objects are usually seen as a hallmark of cognition and symbolism, which are viewed as important features of modern human behavior.

About 35,000 years ago, prehistoric artists across Europe suddenly discovered the female form—and the art world has never been the same. The explosion of voluptuous female figurines sculpted out of limestone, ivory, and clay directly inspired Picasso and Matisse. Researchers have debated the figurines' meaning for decades. Now, two scientists think they have the answer. Presenting their work here last week at the European Palaeolithic Conference, they claimed that the objects started off as celebrations of the female form, then later became symbols that tied together a growing human society.

Paul Davies, a British-born theoretical physicist, cosmologist, astrobiologist and Director of the Beyond Center for Fundamental Concepts in Science and Co-Director of the Cosmology Initiative atArizona State University, says in his new book The Eerie Silence that any aliens exploring the universe will be AI-empowered machines. Not only are machines better able to endure extended exposure to the conditions of space, but they have the potential to develop intelligence far beyond the capacity of the human brain.

Man-made life is a thing of fiction, relegated to things like Frankenstein. But scientists are coming close to something almost like it.

In this paper he and his co-authors discuss a symbol found at several Mesoamerican sites consisting of a cross concentric with one or more circles, with the arms of the cross usually extending beyond the circle(s). These symbols were usually made by pecking a series of dots into either a rock face or the floor of a room, and their alignments appear to have often been significant. They are most common at Teotihuacan, where they were generally oriented with the arms of the cross aligned with the city’s street grid. This orientation had led some earlier authors to interpret them as surveying marks used in laying out the streets. The authors of this paper consider that interpretation a possibility, but not necessarily the only one. There are other examples of these symbols in sites near Teotihuacan that have other orientations, some of which seem to align with prominent landmarks on the horizon that may have been used in astronomical observations.
