Ancient viral elements in RNA kickstart bone repair
Around half of the human genome is composed of DNA fragments originating from ancient viruses. These "transposable elements" (TEs) are now known to play various roles in modulating gene expression and disease development. Now, an international team l.....»»
Saturday Citations: Color vision created demand for colorful animals; observing black hole light echoes; deadlines!
This week, researchers hypothesized that human culture is distinguished from cultures of other species like whales by unique open-endedness—the ability to communicate and understand an infinite number of possibilities. An ancient unicellular organi.....»»

Genetic repair via CRISPR can inadvertently introduce other defects, researchers show
The CRISPR molecular scissors have the potential to revolutionize the treatment of genetic diseases. This is because they can be used to correct specific defective sections of the genome. Unfortunately, however, there is a catch: under certain condit.....»»
Burial chamber and grave goods of ancient Egyptian priestess discovered in Asyut
An international team of archaeologists led by Professor Jochem Kahl from Freie Universität Berlin has made an incredible discovery in the necropolis of Asyut, Egypt. Researchers discovered the burial chamber of the ancient Egyptian priestess Idy, d.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Reconstructing plesiosaur swimming styles with a bio-inspired control system
A research group may have unraveled the mystery behind the locomotion of the ancient marine reptile, the plesiosaur, by recreating a bio-inspired control system that accounts for motion adjustment......»»
Designs on ancient stone cylinders correspond to origin of writing in Mesopotamia, researchers discover
The origins of writing in Mesopotamia lie in the images imprinted by ancient cylinder seals on clay tablets and other artifacts. A research group from the University of Bologna has identified a series of correlations between the designs engraved on t.....»»

An international team led by scientists of GSI/FAIR in Darmstadt, Johannes Gutenberg University Mainz and the Helmholtz Institute Mainz, succeeded in determining the chemical properties of the artificially produced superheavy elements moscovium and n.....»»
Portal to the past: Geologist identifies metamorphic rock as a crucial feature of the ancient Earth"s carbon cycle
If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31. During the Proterozoic Eon—2.5 billion years to 543 million years ago—the sun was still a young star, much dimmer than today,.....»»

Learning more about supernovae through stardust
Most of the diverse elements in the universe come from supernovae. We are, quite literally, made of the dust of those long-dead stars and other astrophysical processes. But the details of how it all comes about are something astronomers strive to und.....»»
