In recent years, high-profile claims in the academic literature and popular press have alleged that the sugar industry paid scientists in the 1960s to play down the link between sugar and heart disease and emphasize instead the dangers of dietary fat. In a new article in the journal Science, historians at Columbia University's Mailman School of Public Health and the City University of New York challenge those claims through a careful examination of the evidence.
It turns out that nobody knows when rabbits were domesticated. Despite a well-cited story of the domestic bunny's origins, a review published on Feb. 14 in Trends in Ecology and Evolution finds that historical and archaeological records and genetic methods all suggest different timeframes for its domestication. But the researchers involved in the study don't think this puzzle is a dead end. Instead, they believe it's an indication that domestication happens on a continuum.
The evolution of human biology should be considered part and parcel with the evolution of humanity itself, proposes Nicole Creanza, assistant professor of biological sciences. She is the guest editor of a new themed issue of the Philosophical Transactions of the Royal Society B that takes an interdisciplinary approach to human evolution.
New research provides the strongest evidence to date that the race of a political officeholder can have a significant effect on policy -- at least historically.
University of Washington researchers reconstructed prehistoric projectiles and points from ancient sites in what is now Alaska and studied the qualities that would make for a lethal hunting weapon. By examining and testing different projectile points, the team has come to a new understanding about the technological choices people made in ancient times.
A new study investigating US and territorial government energy policies and industrial contracts in Puerto Rico argues that energy colonialism has played a central role in the country's current humanitarian crisis.
A jawbone complete with teeth recently discovered at Israel's Misliya cave by Tel Aviv University and University of Haifa researchers has now been dated to 177,000-194,000 years ago. The finding indicates that modern humans were present in the Levant at least 50,000 years earlier than previously thought.
While it is largely believed that horses simply evolved with fewer digits, researchers at New York Institute of Technology College of Osteopathic Medicine (NYITCOM) pose a new theory that suggests remnants of all five toes are still present within the hooves of the horse.
A genome-wide study of the people of Ireland reveals a previously hidden genetic landscape, shaped through geography and historical migrations. Ross Byrne and Russell McLaughlin of Trinity College Dublin in Ireland report their findings Jan. 25, 2018, in PLOS Genetics.
Until recently, very little was known about the genetic relationship between modern humans of the Upper Paleolithic age (the period of time between 50,000 and 10,000 years ago, also called the Late Stone age) and today's populations. But with direct DNA sequencing, researchers are discovering unexpected genetic connections between individuals on opposing sides of Eurasia. These suggest a complex history that may represent an early population structure that eventually led to Europeans and Asians.
