During Earth's last glacial period, temperatures on the planet periodically spiked dramatically and rapidly. A new article suggests that mathematics from information theory could offer a powerful tool for analyzing and understanding these mysterious events.
Read moreResearcher finds evidence of ancient solar magnetic storms based on cuneiform astrological records and carbon-14 dating. This work may help with our understanding of intense solar activity that can threaten modern electronics.
Read moreHumans are diurnal — we are active in the day and sleep at night. But diurnalism is by far the exception rather the rule in mammals. About 250-230 million years ago, the mammalian ancestors, called the therapsids, became exclusively nocturnal, and stayed so until the demise of the dinosaurs 66 million years ago.
Read moreRecent archaeological investigations in the Tollense Valley by a research team has unearthed a collection of 31 unusual objects. Researchers believe this is the equipment of a Bronze Age warrior who died on the battlefield 3,300 years ago. This unique find was discovered by a diving team. It may have been protected in the river from the looting after the fighting.
Read moreWhat does the presence of 1,000 year old water mean for the future of water supplies under the desert regions of Saudi Arabia, Iraq, Jordan, Oman, Yemen and the United Arab Emirates? New research has sought to identify how much good water is available in the Arabian Peninsula, where water is stored in what are known as 'fossil aquifers.'
Read moreSome corals can recover after massive mortality episodes caused by the water temperature rise. This survival mechanism in the marine environment — known as rejuvenation — had only been described in some fossil corals so far. A new study reveals the first scientific evidence of the rejuvenation phenomenon in vivo in Cladocora caespitosa coral colonies, in the marine reserve in Columbrets, in the coast of Castellón.
Read moreUsing innovative new methods researchers have built a new index that uses data from books and newspaper to track levels of national happiness from 1820. Their research could help governments to make better decisions about policy priorities.
Read moreA new study explores the chemistry as well as the complicated and alarming history of DFDT, a fast-acting insecticide.
Read moreThe Neolithic Agricultural Revolution is one of the most thoroughly-studied episodes in prehistory. But a new article shows that most explanations for it don't agree with the evidence, and offers a new interpretation.
Read moreArchaeogenetic analyses provide new insights into social inequality 4,000 years ago: nuclear families lived together with foreign women and individuals from lower social classes in the same household.
