Their study has been published in the Quarterly J
Researchers offer new interpretation of a 4,000-year-old cemetery
Fundamental technological changes often also cause profound social shifts. This is not only evident in the current case of digitalization, but also in the case of industrialization in the 19th century or the introduction of bronze as a work material about 4,000 years ago. Understanding such transitional periods in the past can therefore also help to better classify current processes.

The Puritans waged the first 'War on Christmas'
Long before the Grinch stole Christmas or "Bah! Humbug!" captured Scrooge's bitterness, the Puritans sought to put a permanent end to Yuletide merriment. For them, the acts of toasting (especially with alcohol), gift giving , and even neighborly caroling had no place in honoring the birth of Jesus Christ. Why were the Puritans so opposed to these celebrations? In short, it came down to scripture
Russia Finds Hole in Spacecraft Docked to International Space Station
Sprung a Leak A Russian Soyuz spacecraft, currently docked to the International Space Station and tentatively scheduled to return three astronauts to Earth, sprung a leak last week and sprayed a massive mist of coolant into outer space.

A team of researchers from Frankfurt am Main and Giessen has now discovered milder melittin variants in evolutionarily older wild bee sp
Using drones to monitor volcanoes: Researchers analyze volcanic gases with the help of ultra-lightweight sensor systems
The main gases released by volcanoes are water vapor, carbon dioxide, and sulfur dioxide. Analyzing these gases is one of the best ways of obtaining information on volcanic systems and the magmatic processes that are underway. The ratio of carbon dioxide levels to those of sulfur dioxide can even reveal the likelihood of an impending eruption. Drones are employed to carry the necessary analytical
New software based on Artificial Intelligence helps to interpret complex data
Experimental data is often not only highly dimensional, but also noisy and full of artefacts. This makes it difficult to interpret the data. Now a team has designed software that uses self-learning neural networks to compress the data in a smart way and reconstruct a low-noise version in the next step. This enables it to recognize correlations that would otherwise not be discernible. The software

Orangutan communication sheds light on human speech origins
Research finds orangutans communicate using a complex repertoire of consonant-like calls, more so than African apes. Previous research has only linked the evolution of human language with the voiced-vowel sounds produced by non-human primates, despite human language being composed of vowel and consonant sounds. Orangutans' tree-dwelling nature means they use their mouth, lips and jaw as a 'fifth h
Humans continue to evolve with the emergence of new genes
Modern humans evolutionarily split from our chimpanzee ancestors nearly 7 million years ago, yet we are continuing to evolve. 155 new genes have been identified within the human lineage that spontaneously arose from tiny sections of our DNA. Some of these new genes date back to the ancient origin of mammals, with a few of these 'microgenes' predicted to be associated with human-specific diseases.
