Roman Civilisation Travelled Further than History Books Tell Us

A University of Exeter archaeologist’s research has uncovered the largest Roman settlement ever found in Devon. The discovery could force us to rewrite the history of the Romans in Britain.

The discovery of a large Roman Settlement in Devon was the result of a chance metal detecting coin find.  Danielle Wootton, the Finds Liaison Officer for the Portable Antiquities Scheme (PAS) and archaeologist at the University of Exeter was called on to investigate further. (more…)

The Pew Research Center recently reported that the wealth gap between American whites and blacks is the widest since the United States began tracking the statistic in 1984 — with whites, on average, having 20 times the net worth of blacks. However, another recent study contends traditional measures of prosperity that only look at economic factors, while important, are not the best gauges of overall well-being. (more…)

Open, grassy environments accompanied human evolution

Scientists using chemical isotopes in ancient soil to measure prehistoric tree cover–in effect, shade–have found that grassy, tree-dotted savannas prevailed at most East African sites where human ancestors and their ape relatives evolved during the past six million years. (more…)

Roadblocking Cancer: How Combo Therapies Can Overcome Drug Resistance in Melanoma

About 50 to 60 percent of patients with melanoma have a mutation in the BRAF gene that drives the growth of their cancer. In clinical trials, most of these patients have responded remarkably well to two novel agents that inhibit the gene, but unfortunately, the response is almost always limited in duration, as the cancer develops a resistance to the drugs.

WHOI Study Reports Microbes Consumed Oil in Gulf Slick at Unexpected Rates

More than a year after the largest oil spill in history, perhaps the dominant lingering question about the Deepwater Horizon spill is, “What happened to the oil?” Now, in the first published study to explain the role of microbes in breaking down the oil slick on the surface of the Gulf of Mexico, Woods Hole Oceanographic Institution (WHOI) researchers have come up with answers that represent both surprisingly good news and a head-scratching mystery.

In research scheduled to be published in the Aug. 2 online edition of Environmental Research Letters, the WHOI team studied samples from the surface oil slick and surrounding Gulf waters. They found that bacterial microbes inside the slick degraded the oil at a rate five times faster than microbes outside the slick—accounting in large part for the disappearance of the slick some three weeks after Deepwater Horizon’s Macondo well was shut off.
