A new study indicates that clay minerals, formed when water is present for long periods of time, cover a larger portion of Mars than previously thought. Clays were in some of the rocks studied by Opportunity when it landed at Eagle crater in 2004. The rover only detected acidic sulfates and has since driven about 22 miles to Endeavour Crater and clay minerals have been detected using a spectroscopic analysis from the Mars Reconnaissance Orbiter. The clays also exist in the Meridiani plains that Opportunity rolled over as it trekked toward its current position. 

Trousers have to be tried on – the variation between size labeling and actual clothing size is huge. This is shown by the report "Large? Clothing sizes and size labeling", which looks at the relationship between clothing sizes and the actual clothing measurements as well as consumers' views on and experiences of this.

The study of epigenetics in psychiatry promises several key advances, as noted by Eric J. Nestler, M.D., Ph.D., a Deputy Editor for Biological Psychiatry and an expert in this field.

First, it enables, for the first time, direct study of mechanisms controlling transcription, the process of expressing the genetic information coded within DNA, in the brains of behaving animals as well as in brain tissue from humans studied at autopsy.

Second, some epigenetic changes in the brain are likely to be extremely long-lived, and thereby represent potential mechanisms by which life events, or psychotropic drugs or even psychotherapy, can produce stable, long-lasting changes in behavior.

It may not work with the ladies, but when it comes to leading a team tasked with developing new products and bringing them to market, new research from North Carolina State University shows that being nice and playing well with others gives you a very real competitive advantage. One new study shows that project managers can get much better performance from their team when they treat team members with honesty, kindness and respect.

A second study shows that product development teams can reap significant quality and cost benefits from socializing with people who work for their suppliers.

In the aftermath of the Newtown, CT shooting, people are searching for answers. The mental illness aspect is obvious, much like with the psychology graduate student in Colorado who opened fire on viewers at a theater, but this time the focus is on the anti-social tendencies of Adam Lanza and how they were exacerbated by video game and Hollywood violence.

In a discovery that may prove important for cognitive science, our understanding of nature and applications for robot vision, researchers at the University of Adelaide have found evidence that the dragonfly is capable of higher-level thought processes when hunting its prey.

Originating from Africa, India, and the Middle East, frankincense oil has been found to have many medicinal benefits. Now, an enriched extract of the Somalian Frankincense herb Boswellia carteri has been shown to kill off bladder cancer cells. Research presented in the open access journal, BMC Complementary and Alternative Medicine, demonstrates that this herb has the potential for an alternative therapy for bladder cancer.

Bladder cancer is twice as common in males as it is in females. In the US, bladder cancer is the fourth most common type of cancer in men, whilst in the UK it is the seventh most common cause of death amongst males.

CAMBRIDGE, Mass.--A rising tide is said to lift all boats. Rising global temperatures, however, may lead to increased disparities between rich and poor countries, according to a recent MIT economic analysis of the impact of climate change on growth.

After examining worldwide climate and economic data from 1950 to 2003, Benjamin A. Olken, associate professor in the Department of Economics, concludes that a 1 degree Celsius rise in temperature in a given year reduces economic growth by an average of 1.1 percentage points in the world's poor countries but has no measurable effect in rich countries.

Olken says his research suggests higher temperatures will be disproportionately bad for the economic growth of poor countries compared to rich countries.

(PHILADELPHIA) A novel signaling pathway plays a significant role in the production of aldosterone, a hormone that promotes heart failure after a myocardial infarction, according to a study conducted by Thomas Jefferson University researchers.

The findings, which will be published online this week in Proceedings of the National Academy of Sciences, show that aldosterone production is mediated by a protein called beta-arrestin-1. Beta-arrestin-1 binds to angiotensin II receptors when they are activated by angiotensin II.

Prehistoric farming communities in Europe constructed water wells out of oak timbers - it seems early farmers were skilled carpenters long before metal was discovered or used for tools. 

 These first Central European farmers migrated from the Great Hungarian Plain approximately 7,500 years ago, and left an archaeological trail of settlements, ceramics and stone tools across the fertile regions of the continent, a record named Linear Pottery Culture (Linearbandkeramik - LBK). However, much of the lifestyle of these early settlers is still a mystery, including the climate they lived in and technology or strategies they used to cope with their surroundings.
