Cities may not look like they once looked, but those of ancient times and today had a lot in common when it came to intangibles.

Despite notable differences in appearance and governance, ancient human settlements function in much the same way as modern cities, according to new findings by researchers at the Santa Fe Institute and the University of Colorado Boulder.

City planning says that as modern cities grow in population, so do their efficiencies and productivity. A city's population outpaces its development of urban infrastructure, for example, and its production of goods and services outpaces its population. What's more, these patterns exhibit mathematical regularity and predictability, a phenomenon called "urban scaling."

Researchers have quantified how the Greenland Ice Sheet reacted to a warm period 8,000-5,000 years ago, when temperatures were 2-4 degrees C warmer than present and so could inform us what might happen if the same occurred now. 

Dr. Nicolaj Krog Larsen, Aarhus University in Denmark and Professor Kurt Kjær, Natural History Museum of Denmark, ventured off to Greenland to investigate how fast the Greenland Ice Sheet reacted to past warming. Over six summers, they cored lakes in the ice-free land surrounding the ice sheet. The lakes act as a valuable archive as they store glacial meltwater sediments in periods where the ice is advanced. That way it is possible to study and precisely date periods in time when the ice was smaller than present.

So, is justice really blind? Who knows? 

But, with the right recipe it can become deaf and dumb rather quickly.Here is the recipe. Mix the following in equal quantities: Junk science and medicine, a misguided and politically-driven regulatory agency, a flawed legal system, predatory trial lawyers, a self-anointed know-nothing consumer "advocate," greed, and a company with deep pockets, and voila: the perfect mix. 

Norwegian women who choose to have children often say goodbye to their careers. Men, on the other hand, tarry on. Norway has, since the 1800s, come a long way towards a more egalitarian society, but when a child enters the relationship between a woman and a man the consequences for the woman are different to those for the man, according to the thesis of Eirin Pedersen at the Department of Sociology and Human Geography at University of Oslo.

The connections between technology, urban trading, and international economics which have come to define modern living are nothing new.

Back in the first millennium AD, the Vikings were expert at exploring these very issues.

Why did the first human populations migrate out of Africa? It is the biggest debate in anthropology but no one can be sure of the answer. When it happened can at least be an informed debate and two hypotheses dominate the cultural landscape - but they both involve a common denominator that might shed light on why.

One popular belief is that human populations expanded rapidly from Africa to southern Asia via the coastlines of Arabia 50,000 or 60,000 years ago while another is that dispersal into the Arabian interior began 75,000 or even up to 130,000 years ago, but during multiple smaller phases as increased rainfall provided sufficient freshwater to support expanding populations.

Both involve climate change. 

Governments and taxpayers deserve to know that their money is being spent on something worthwhile to society. Individuals and groups who are making the greatest contribution to science and to the community deserve to be recognized.

For these reasons, all research has to be assessed. Judging the importance of research is often done by looking at the number of citations a piece of research receives after it has been published.

Patients who increased doses of opioid medicines to manage chronic pain were more likely to experience an increase in depression, according a new paper in Pain which expands findings in a previous study of Veterans Administration (VA) patients.

Jeffrey Scherrer, Ph.D., associate professor for family and community medicine at Saint Louis University, and his colleagues studied questionnaires from 355 patients from nine practices in the Residency Research Network of Texas who reported chronic low back pain initially and at one-year and two-year follow ups. The respondents to the survey were 72.4 percent female, older than 46 (75.2 percent) and mostly of Hispanic or African-American descent (57.5 percent).
