Researchers believe that ancient stone tools discovered in Brazil are the work of capuchin monkeys, not early humans, the art and design website Artnet reported, citing an academic article. “We are confident that the early archeological sites from Brazil may not be human-derived but may belong to capuchin monkeys,” wrote archaeologist Agustín M. Agnolín and

In a recent study published in Astronomy and Astrophysical Letters, a team of researchers at the Massachusetts Institute of Technology (MIT) used various computer models to examine 69 confirmed binary black holes to help determine their origin and found their data results changed based on the model’s configurations. Essentially, the input consistently altered the output,

The ancient Romans were masters of building and engineering, perhaps most famously represented by the aqueducts. And those still functional marvels rely on a unique construction material: pozzolanic concrete, a spectacularly durable concrete that gave Roman structures their incredible strength. Even today, one of their structures – the infamous Pantheon, still intact and nearly 2,000

Scientists have engineered a species of roundworm (Caenorhabditis elegans) to absorb light to live a significantly longer life. By adding a light-sensitive trigger to power-converting organelles known as mitochondria, researchers from the US and Germany extended the time sufficient energy could be provided to the cells before aging processes took over. While the scientists emphasize

Mini brains grown in a lab from stem cells spontaneously developed rudimentary eye structures, scientists reported in a fascinating 2021 paper. On tiny, human-derived brain organoids grown in dishes, two bilaterally symmetrical optic cups were seen to grow, mirroring the development of eye structures in human embryos. This incredible result could help us to better

Cloaked by the shadows of enchanting Asian woodlands, strange growths can be seen peeking out from between leaf litter like the ghosts of long-dead flowers. The plant’s foliage lacks green pigment having forsaken photosynthesis in favor of an alternative source of nutrients on the forest floor, one stolen from fungi many other plants consider friends

Mummification may never have been intended to preserve the bodies of ancient Egyptians after death, experts say, a sharp contrast to the popular understanding of the practice. An increasing number of archaeologists say that the preservative effects of mummification were likely accidental and blame early modern Egyptologists for propagating a misunderstanding based on little evidence.

A new analysis of dust retrieved from the Moon suggests that water bound up in the lunar surface could originate with the Sun. More specifically, it could be the result of bombardment of hydrogen ions from the solar wind, slamming into the lunar surface, interacting with mineral oxides, and bonding with the dislodged oxygen. The

Catastrophic floods, crop-wilting droughts, and record heatwaves this year have shown that climate change warnings are increasingly becoming reality, and this is “just the beginning”, experts say, as international efforts to cut planet-heating emissions founder. The year did see some important progress, with major new legislation, particularly in the United States and Europe, as well

In re-examining artifacts from a significant 4,000-year-old Bronze Age burial site near Stonehenge in the UK, archaeologists discovered a toolkit for working with gold objects and coatings that hadn’t previously been identified. The site of the find, the Upton Lovell G2a ‘Wessex Culture’ burial area, was excavated more than 200 years ago and is crucial
