Researchers at Stanford University have stumbled upon a method of making biological tissue, such as skin, muscle and connective tissue, temporarily transparent, allowing the underlying organs to be viewed without the need for x-ray imaging or surgical procedures. The technique could not only one day allow for medical imaging thatread more
Researchers have identified the evolutionary changes to our larynx that enables humans to produce the complex sounds necessary for the development of speech, while our primate relatives are unable to do so, despite having similar physical vocal structures. Paradoxically, the changes that occurred didn’t involve an increase in the complexityread more
A new analysis of ancient DNA has revealed that some species of ice-age megafauna, including woolly mammoths, wild horses and steppe bison, survived much further into the modern era than previously thought. The recovered genetic material taken from soil samples from Canadian permafrost, indicates that some of these species didn’tread more
The discovery of the fossils of a sponge-like creature that dates back to 890 million years ago suggests that simple animals appeared on Earth nearly 350 million years before the oldest known fossilized specimens first appeared in the Earth’s oceans. While the previously oldest known animal fossils, also in theread more
