Ancient remains put teeth into Barker hypothesis

Thu, 04 Feb 2010 00:00:00 EST

(Emory University) Ancient human teeth are telling secrets that may relate to modern-day health: Some stressful events that occurred early in development are linked to shorter life spans."Prehistoric remains are providing strong, physical evidence that people who acquired tooth enamel defects while in the womb or early childhood tended to die earlier, even if they survived to adulthood," says Emory anthropologist George Armelagos, who recently published the first summary of prehistoric evidence for the Barker hypothesis.

Lost Roman law code discovered in London

Tue, 26 Jan 2010 00:00:00 EST

(University College London) Part of an ancient Roman law code previously thought to have been lost forever has been discovered by researchers at UCL's department of history. Simon Corcoran and Benet Salway made the breakthrough after piecing together 17 fragments of previously incomprehensible parchment. The fragments were being studied at UCL as part of the Arts & Humanities Research Council-funded "Projet Volterra" -- a 10-year study of Roman law in its full social, legal and political context.

The sea level has been rising and falling over the last 2,500 years

Tue, 26 Jan 2010 00:00:00 EST

(University of Haifa) The sea level in Israel has been rising and falling over the past 2,500 years, with a one-meter difference between the highest and lowest levels. This has been shown in a new study supervised by Dr. Dorit Sivan, head of the department of maritime civilizations at the University of Haifa. "Rises and falls in sea level over relatively short periods do not testify to a long-term trend," Dr. Sivan explains.

Stable climate and plant domestication linked

Tue, 12 Jan 2010 00:00:00 EST

(Springer) Sustainable farming and the introduction of new crops relies on a relatively stable climate, not dramatic conditions attributable to climate change. Basing their argument on evolutionary, ecological, genetic and agronomic considerations, Dr. Shahal Abbo, from the Hebrew University of Jerusalem, Israel, and colleagues, demonstrate why climate change is not the likely cause of plant domestication in the Near East. Their thesis is published online in Springer's journal Vegetation History and Archaeobotany.

Ancient Egyptian cosmetics: 'Magical' makeup may have been medicine for eye disease

Mon, 11 Jan 2010 00:00:00 EST

(American Chemical Society) There's more to the eye makeup that gave Queen Nefertiti and other ancient Egyptians royals those stupendous gazes and legendary beauty than meets the eye. Scientists in France are reporting that the alluring eye makeup also may have been used to help prevent or treat eye disease by doubling as an infection-fighter. Their findings are scheduled for the Jan. 15 issue of ACS' Analytical Chemistry, a semi-monthly journal.

Most ancient Hebrew biblical inscription deciphered

Thu, 07 Jan 2010 00:00:00 EST

(University of Haifa) Professor Gershon Galil of the department of biblical studies at the University of Haifa has deciphered an inscription dating from the 10th century BCE (the period of King David's reign), and has shown that this is a Hebrew inscription. The discovery makes this the earliest known Hebrew writing. The significance of this breakthrough relates to the fact that at least some of the biblical scriptures were composed hundreds of years before the dates presented today in research.

Discovery of 4.4 million-year-old 'Ardi' named 'Breakthrough of the Year'

Thu, 17 Dec 2009 00:00:00 EST

(University of California - Berkeley) The journal Science has named the discovery of "Ardi," the oldest hominid skeleton ever found, its "Breakthrough of the Year 2009." An international team co-led by UC Berkeley's Tim White took 17 years to assemble and analyze the skeleton and thousands of other fossils found with it. The analysis, published in the Oct. 2 Science, revolutionizes our understanding of the earliest human ancestors appearing not long after the human lineage diverged from that of chimps.
