Wild birds as offerings to the Egyptian gods
on September 22, 2020 at 3:22 pm
Millions of mummified ibis and birds of prey, sacrificed to the Egyptian gods Horus, Ra or Thoth, have been discovered in the necropolises of the Nile Valley. Such a quantity of mummified birds raises the question of their origin: were they bred, like cats, or were they hunted? According to a team of scientists that carried out extensive geochemical analyses on mummies, they were wild birds.

How dinosaur research can help medicine
on August 24, 2020 at 2:56 pm
The intervertebral discs connect the vertebrae and give the spine its mobility. The disc consists of a cartilaginous fibrous ring and a gelatinous core as a buffer. It has always been assumed that only humans and other mammals have discs. A misconception, as a research team has now discovered: Even Tyrannosaurus rex could have suffered a slipped disc.

New species of Cretaceous brittle star named in honor of Nightwish vocalist
on August 24, 2020 at 1:20 pm
Palaeontologists have discovered a previously unknown species of brittle star that lived in the shallow, warm sea which covered parts of the present-day Netherlands at the end of the Dinosaur Era. The starfish-like creature was unearthed more than 20 years ago but has only now been identified as new to science.
Animal mummies unwrapped with hi-res 3D X-rays
on August 20, 2020 at 6:38 pm
Three mummified animals from ancient Egypt have been digitally unwrapped and dissected by researchers, using high-resolution 3D scans that give unprecedented detail about the animals' lives -- and deaths -- over 2000 years ago. The three animals - a snake, a bird and a cat - are from the collection held by the Egypt Centre at Swansea University. Previous investigations had identified which animals they were, but very little else was known about what lay inside the mummies.

Exact climate data from the past
on August 10, 2020 at 2:32 pm
Corals and cave carbonates can reveal the temperatures that prevailed at the Earth's surface at the time they formed. An international team of geoscientists has developed a new method that makes it possible to identify whether the composition of these deposits was exclusively controlled by temperature, or if the formation process itself exerted an additional control. The new method allows scientists to determine past Earth surface temperatures more reliably.

on July 22, 2020 at 3:27 pm
A cave in a remote part of Mexico was visited by humans around 30,000 years ago - 15,000 years earlier than people were previously thought to have reached the Americas. Excavations of Chiquihuite Cave, located in a mountainous area in northern Mexico controlled by drugs cartels, uncovered nearly 2000 stone tools from a small section of the high-altitude cave. Analysis of the sediment in the cave uncovered a new story of the colonisation of the Americas.
