Researchers investigated the diet of people buried in the Ii Hamina, Northern Finland, cemetery from the 15th to the 17th centuries by analysing isotopes in the bones of the deceased. Isotopes preserve information on the various nutrient sources used by humans during their lifetime. A study published in the Environmental Archaeology journal reveals that the dominant protein source was small fish, such as roach or Baltic herring.
In a study that has implications for humans with inflammatory diseases, researchers have found that, given over a six-week period, the artificial sweetener sucralose, known by the brand name Splenda, worsens gut inflammation in mice with Crohn's disease, but had no substantive effect on those without the condition.
An international collaboration has discovered that early humans in eastern Africa had -- by about 320,000 years ago -- begun trading with distant groups, using color pigments and manufacturing more sophisticated tools than those of the Early Stone Age. These behavioral innovations may represent a response to the rapid environmental and climactic changes occurring at the time.
An anthropology professor from the George Washington University and a team of international collaborators, including scientists from the Smithsonian's National Museum of National History, have discovered that early humans in East Africa used coloring materials and obtained a range of raw materials from distant sources -- activities which imply the existence of social networks -- about 320,000 years ago, much earlier than previously thought.
Gun expenditure log from 1600 and 1601 prove St. Patrick's Day celebrations began in St. Augustine, Fla., and not in Boston or New York.
Izaro Goienetxea, a UPV/EHU researcher, has developed a method for automatically generating new tunes on the basis of a collection or corpus comprising tunes used in bertso [extempore, sung, Basque verse-making]. She has also presented a new way of representing pieces of music and a new method for automatically classifying music. The well-known scientific journal PLOS ONE has reported on the research conducted in the UPV/EHU's Robotics and Autonomous Systems research group.
An international team of researchers have sequenced DNA from individuals from Morocco dating to approximately 15,000 years ago. This is the oldest nuclear DNA from Africa ever successfully analyzed. The study, published in Science, shows that the individuals, dating to the Late Stone Age, had a genetic heritage that was in part similar to ancient Levantine Natufians and an uncharacterized sub-Saharan African lineage to which modern West Africans are genetically closest.
Three new studies highlight major environmental, ecological and technological changes that occurred in East Africa preceding the Middle Stone Age roughly 300,000 years ago, around the time that anatomically modern humans were evolving.
Scientists discovered that early humans in East Africa had -- by about 320,000 years ago -- begun trading with distant groups, using color pigments and manufacturing more sophisticated tools than those of the Early Stone Age, tens of thousands of years earlier than previous evidence has shown in eastern Africa. As earthquakes remodeled the landscape and climate fluctuated between wet and dry conditions, technological and social innovation would have helped early humans survive unpredictable conditions.
The emotional and sexual abuse that some children endure can lead them to commit crimes later in life.
