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.....»»
Earth underwent a massive, rapid melting period after the last global ice age, new study suggests
At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results from a Virginia Tech-led study provide the first direct geochemical evidence of the slushy planet—other.....»»
Deaf male mosquitoes don"t mate, researchers discover
Romance is a complex affair in humans. There's personality, appearance, seduction, all manner of physical and social cues. Mosquitoes are much more blunt. Mating occurs for a few seconds in midair. And all it takes to woo a male is the sound of a fem.....»»
Archaic dolphin could hear high frequency sounds
A team of researchers led by SNSB paleontologist Gertrud Rößner has discovered a new prehistoric dolphin species. Analyses of its inner ear confirm that this dolphin had excellent hearing abilities in the high-frequency range, which is very similar.....»»
Novel flame aerosol system excels at creating nanoparticles

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,.....»»
Not the usual suspects: Research reveals novel genetic basis of pest resistance to biotech crops
If left unchecked, insect pests can devastate crops. To minimize damage and reduce the need for insecticide sprays, crops have been genetically engineered to produce bacterial proteins that kill key pests but are not harmful to people or wildlife. Ho.....»»
Beta cells: New insights into the structure, interactions and neuronal networking of primary cilia
Dysfunctions of the tiny cell processes (primary cilia) of the pancreatic beta cells could be a cause of type 2 diabetes. Little is known about the structure and function of these cilia. An international research team led by DZD researchers from the.....»»
