Researchers have discovered a new kind of glycan (sugar chain) that survives even in a 4-million-year-old animal fossil from Kenya, under conditions where ancient DNA does not.

When ancient fossil DNA isn't available, ancient glycans may help trace human evolution

A 176,000 year old Neanderthal construction site

Neanderthals created two ring-shaped structures and several round piles out of almost 400 broken stalagmites deep inside Bruniquel Cave, France, 176,000 years ago.

These structures are over 300 meters from the cave entrance, and some of them were clearly burned by fires set by Neanderthals.

The function of the structures - which are among the oldest well-dated constructions made by early humans - is unknown, but they may have had a domestic or ritual function.

The research was reported in the journal Nature by Jacques Jaubert and colleagues on May 25, 2016.

The Anthropocene defines Earth's most recent geologic time period as being human-influenced, or anthropogenic, based on overwhelming global evidence that atmospheric, geologic, hydrologic, biospheric and other earth system processes are now altered by humans.

The word combines the root "anthropo", meaning "human" with the root "-cene", the standard suffix for "epoch" in geologic time.

The Anthropocene is distinguished as a new period either after or within the Holocene, the current epoch, which began approximately 10,000 years ago (about 8000 BC) with the end of the last glacial period.

This animation shows every recorded earthquake in sequence as they occurred from January 1, 2001, through December 31, 2015, at a rate of 30 days per second. The earthquake hypocenters first appear as flashes then remain as colored circles before shrinking with time so as not to obscure subsequent earthquakes.
