Newly discovered notes show for the first time the Venetian doctor who invented the thermometer and helped lay the foundations for modern medical treatment also played a key role in shaping our understanding of chemistry.
In human history, the transition from hunting and gathering to farming is a significant one. As such, hunter-gatherers and farmers are usually thought about as two entirely different sets of people. But researchers reporting new ancient DNA evidence in Current Biology on May 25 show that in the area we now recognize as Romania, at least, hunter-gatherers and farmers were living side by side, intermixing with each other, and having children.
A-tisket, a-tasket. You can tell a lot from a basket. Especially if it's from ancient ruins of a civilization inhabited by humans 15,000 years ago. An archaeologist is among the team who made a groundbreaking discovery in coastal Peru -- home to one of the earliest pyramids in South America. Thousands of artifacts, including elaborate hand-woven baskets, show that early humans in that region were a lot more advanced than originally thought and had very complex social networks.
Researchers have developed a new method to read imperfections in teeth caused by a lack of sunlight, creating a powerful tool to trace events ranging from human evolution and migration out of Africa to the silent damage of vitamin D deficiency that continues to affect 1 billion worldwide.
The Mediterranean shores stretching between Sicily, Southern Italy and the Southern Balkans witnessed a long series of migration processes and cultural exchanges. Despite this complex history there is a shared genetic continuity, extending from Sicily to Cyprus, where the populations of certain Greek-speaking islands appear genetically closer to Southern Italian populations than to populations from continental Greece.
Around 66 million years ago, at the end of the Cretaceous period, a giant asteroid crashed into the present-day Gulf of Mexico, leading to the extinction of the non-avian dinosaurs. How plants were affected is less understood, but fossil records show that ferns were the first plants to recover many thousands of years afterward. Now, a team including Cornell researchers reports the discovery of the first fossilized flowers from South America, and perhaps the entire Southern Hemisphere, following the extinction event.
Which came first, overall bigger brains or larger brain regions that control specialized behaviors? Neuroscientists have debated this question for decades, but a new Cornell University study settles the score.
James Cook University scientists have discovered that primitive hominids lived in Africa at the same time as humans -- the first time this has been established.
Probing deeper into the South African cave system known as Rising Star, which last year yielded the largest cache of hominin fossils known to science, an international team of researchers has discovered another chamber with more remains of a newfound human relative, Homo naledi. The discovery of the new fossils representing the remains of at least 3 juvenile and adult specimens includes a 'wonderfully complete skull,' says University of Wisconsin-Madison anthropologist John Hawks.
PhD student Marina Silva identifies the origins of Indian populations comprising migrating humans from Africa, Iran and Central Asia over a period of 50,000 years.
