If you looked up 66 million years ago you might have seen, for a split second, a bright light as a mountain-sized asteroid burned through the atmosphere and smashed into Earth. It was springtime and the literal end of an era, the Mesozoic.If you somehow survived the initial impact, you would have witnessed the devastation that followed. Raging firestorms, megatsunamis, and a nuclear winter lasting months to years. The 180-million-year reign of non-avian dinosaurs was over in the blink of an ...read more

The recent discovery of a long-legged bird that lived about 150 million years ago shows how the evolution of modern birds occasionally took an odd turn. The bird also fills an important gap in the fossil record of early birds, which evolved from theropod dinosaurs.Fujianvenator prodigiosus “exhibits a bizarre assembly of morphologies” borrowed from various groups of early birds, including the avialans that preceded modern birds, according to a press release.

There’s a lot that can be done with a blank slab of stone. It can be scored, splattered with paint, or plastered with clay. Transformed with a smattering of scrapes or scratches or a smear of red ochre, its surface can become a swirl of abstract shapes or a field of frolicking antelopes. Ancient rock artists tried it all, becoming remarkably skilled at representing themselves and their surroundings in stone.In the Later Stone Age of southern Africa between around 5,000 years and 1,000 years ag ...read more

A single bite from a tick can cause a permanent allergy to pork, beef and other kinds of red meat.

Much of the coverage of the wildfire that destroyed the Maui city of Lahaina on Aug. 8 labels it the deadliest wildfire “in modern American history” or “in America in over a century.” With 115 people known dead and dozens still missing, it’s hard to grasp what a worse fire could look like.But on the evening of Oct. 8, 1871, the deadliest wildfire in recorded world history burned through 1.5 million acres of northern Wisconsin. By the next day, the booming town of Peshtigo had been anni ...read more

When and where did our ancestors first fashion footwear? We cannot look to physical evidence of shoes for the answer, as the perishable materials from which they were made would no longer be evident. Ichnology, the study of fossil tracks and traces, can help to answer this unresolved question through a search for clear evidence of footprints made by humans who were shod – that is, wearing some kind of foot covering.But this is no simple endeavour, as our research team from the Cape south coas ...read more

Research involving human embryos is famously difficult and fraught with ethical quandaries, but a new synthetically derived model could open new doors in the study of infertility and birth defects.The model comes from the Weizmann Institute of Science in Israel and follows years of research by labs around the world into producing a similar clump of cells. The team led by professor Jacob Hanna claims that their latest iteration is the most advanced so far and contains all the hallmarks of a human ...read more
