Ancient-human species mingled in Siberia’s hottest property for 300,000 years

Neanderthals and Denisovans both called Denisova Cave home — and Homo sapiens might have, too. |SOURCE| Neanderthals and Denisovans might have lived side by side for tens of thousands of years, scientists report in two papers in Nature. The long-awaited studies are based on the analysis of bones, artefacts and sediments from Denisova Cave in [...] Read more

First Detection of the pre-biotic Molecule Glycolonitrile (HOCH2CN) in the Interstellar Medium

Theories of a pre-RNA world suggest that glycolonitrile (HOCH2CN) is a key species in the process of ribonucleotide assembly, which is considered as a molecular precursor of nucleic acids. |SOURCE| In this Letter, we report the first detection of this pre-biotic molecule in the interstellar medium (ISM) by using ALMA data obtained at frequencies [...] Read more

Yale researchers track the birth of memories

How and when the ability to form and store memories arises are topics of great interest to neuroscientists. Now Yale researchers have identified three distinct stages in brain development that occur before episodic memories can form. |SOURCE| Yale scientists measured brain activity in the hippocampus of newborn rats and found at the beginning of [...] Read more

Mighty morphing materials take complex shapes

Rice University demonstrates sophisticated shape-shifters for soft robots, biomedical applications. |SOURCE| Rice University scientists have created a rubbery, shape-shifting material that morphs from one sophisticated form to another on demand. The shapes programmed into a polymer by materials scientist Rafael Verduzco and graduate student Morgan [...] Read more
