At the far end, they found an upside-down human skull fused into the rock alongside a large collection of other human bones.The skull’s jutting brow was covered in a layer of pearl-like coralloid, calcium deposits otherwise known as cave popcorn. Much of the remains were covered in some form of the mineral that had leached down from the surrounding limestone.Today, scientist ...read more

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
Alzheimer’s takes a toll on its patients. As the disease progresses, a person’s personality deteriorates, and so, too, does their judgement, their memory, and their motor skills. But a diagnosis of Alzheimer’s dementia affects much more than the individual who is diagnosed. That’s because the disease fosters feelings of fear and loss for the family, friends, and loved ones who witness its destruction, while also causing concerns for those same individuals about their own futures with the ...read more
The James Webb Space Telescope (JWST) has brought us marvelous images of whirlpool galaxies, supernovas and even questionable space phenomena.

The telescope isn’t on this planet — it orbits the sun. The JWST was launched on December 25, 2021, at 7:20 a.m. EST. In total, it weighs more than 1 ...read more
In 1914, the biggest story in newspapers across the U.S. was the world war that had recently broken out in Europe with a big question mark hanging over whether the U.S. would take part. The same story dominated the U.S. newspapers in 1915, 1917 and 1918. But in 1916, another story captured the attention of the American public, one that is much less well known today.In that year, the U.S. Army entered Mexico in pursuit of a Mexican paramilitary force that had attacked the town of Columbus in New ...read more
