Public Release: 28-Aug-2014
Ancient metal workers were not slaves but highly regarded craftsmen
In the course of ongoing excavations at Timna Valley, Tel Aviv University archaeologists analyzed remnants of food eaten by copper smelters 3,000 years ago. This analysis indicates that the laborers operating the furnaces were in fact skilled craftsmen who enjoyed high social status and adulation. They believe their discovery may have ramifications for similar sites across the region.

Walking fish reveal how our ancestors evolved onto land
About 400 million years ago a group of fish began exploring land and evolved into tetrapods -- today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries.

Stone-tipped spears lethal, may indicate early cognitive and social skills
Attaching a stone tip on to a wooden spear shaft was a significant innovation for early modern humans living around 500,000 years ago. However, it was also a costly behavior in terms of time and effort to collect, prepare and assemble the spear. Arizona State University and University of Cape Town researchers conducted controlled experiments to learn if there was a 'wounding' advantage between using a wooden spear or a stone-tipped spear.

Stone-tipped spears more damaging than sharpened wooden spears
Experimental comparison may show that stone-tipped spears do not penetrate as deep, but may still cause more damage, than sharpened wooden spears.

SA's Taung Child's skull and brain not human-like in expansion
By subjecting the skull of the first australopith discovered to the latest technologies in the Wits University Microfocus X-ray Computed Tomography facility, researchers are now casting doubt on theories that Australopithecus africanus shows the same cranial adaptations found in modern human infants and toddlers.

New research shows seals and sea lions likely spread tuberculosis to humans
Scientists who study tuberculosis have long debated its origins. New research shows that tuberculosis likely spread from humans in Africa to seals and sea lions that brought the disease to South America and transmitted it to Native people there before Europeans landed on the continent.

Bone chemistry reveals royal lifestyle of Richard III
A recent study by the British Geological Survey, in association with researchers at the University of Leicester, has delved into the bone and tooth chemistry of King Richard III and uncovered fascinating new details about the life and diet of Britain's last Plantagenet king. This forensic study will feature in a documentary, 'Richard III: The New Evidence,' airing on Channel 4 on Sunday, Aug. 17, at 9 p.m.

Western Wall weathering: Extreme erosion explained
Hebrew University researchers investigating erosion at Jerusalem's Western Wall found that limestone with very small crystals eroded up to 100 times faster and had sometimes receded by tens of centimeters, potentially weakening the wall's structure. The researchers described an accelerated erosion process causing some rocks to become more weathered than others, and showed that chemo-mechanical erosion extends down to the tiny micron scale. The findings could help guide preservation techniques at cultural heritage sites worldwide.

Excavation of ancient well yields insight into Etruscan, Roman and medieval times
During a four-year excavation of an Etruscan well at the ancient Italian settlement of Cetamura del Chianti, a team led by a Florida State University archaeologist and art historian unearthed artifacts spanning more than 15 centuries of Etruscan, Roman and medieval civilization in Tuscany.

In October 2004, excavation of fragmentary skeletal remains from the island of Flores in Indonesia yielded what was called 'the most important find in human evolution for 100 years.' Its discoverers dubbed the find Homo floresiensis, a name suggesting a previously unknown species of human.

WSU researchers see violent era in ancient Southwest
In numbers terms, the 20th Century was the most violent in history, with civil war, purges and two World Wars killing as many as 200 million people. But on a per-capita basis, Tim Kohler has documented a particularly bloody period more than eight centuries ago. Between 1140 and 1180, in the central Mesa Verde of southwest Colorado, four relatively peaceful centuries of pueblo living devolved into several decades of violence.

Society bloomed with gentler personalities and more feminine faces
A Duke University study finds that human skulls changed in ways that indicate a lowering of testosterone levels at around the same time that culture was blossoming. Heavy brows were out, rounder heads were in. Technological innovation, making art and rapid cultural exchange probably came at the same time that we developed a more cooperative temperament by dialing back aggression with lower testosterone levels.

Scientists solve 2,000-year-old mystery of the binding media in China's polychrome Terracotta Army
The sculpted Terracotta Warriors positioned to protect the afterlife palaces of China's First Emperor Qin Shihuang (259-210 B.C.) were originally painted to resemble their real-life counterparts: Qin's imperial guards. Since this army was unearthed, scientists have been puzzled over what type of binding medium was used in painting these polychromatic soldiers. Now researchers in Xi'an have identified the binding material using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Violent aftermath for the warriors at Alken Enge
Denmark attracted international attention in 2012 when archaeological excavations revealed the bones of an entire army, whose warriors had been thrown into the bogs near the Alken Enge wetlands in East Jutland after losing a major engagement in the era around the birth of Christ. Work has continued in the area since then and archaeologists and experts from Aarhus University, Skanderborg Museum and Moesgaard Museum have now made sensational new findings.

Fire ecology manipulation by California native cultures
Before the colonial era, 100,000s of people lived on the land now called California, and many of their cultures manipulated fire to control the availability of plants they used for food, fuel, tools, and ritual. Contemporary tribes continue to use fire to maintain desired habitat and natural resources.
