Rice University scientists have produced a detailed analysis of water produced by hydraulic fracturing of three gas reservoirs and suggest environmentally friendly remedies - advanced recycling rather than disposal of "produced" water pumped back out of wells - could calm fears of accidental spillage and save millions of gallons of fresh water a year.
Politicians often say one thing in public and other things in private. That is no surprise, people in all jobs do the same thing.
Saddam Hussein, the genocidal former dictator of Iraq, has left a legacy most despots do not; he recorded so many of his private conversations that political scientists can analyze what he said in private and compare those to his public statements. Their conclusion; he believed what he said.
Very bad man, but he believed in his badness.

It is not a "All your base are belong to us" world in video games any more.
Today, if you want to make a mark in the world of computer games you had better have a good English vocabulary, according to a study by the University of Gothenburg and Karlstad University, Sweden. And games do.
The study confirms what many parents and teachers already suspected: young people who play a lot of interactive English computer games gain an advantage in terms of their English vocabulary compared with those who do not play or only play a little.
Why do so many people in Ontario have inflammatory bowel disease? One in every 200 Ontarians has been diagnosed with IBD, an increase by 64 percent between 1999 and 2008, according to a study by researchers at the Institute for Clinical Evaluative Sciences (ICES), the Children's Hospital of Eastern Ontario (CHEO), and the Ottawa Hospital Research Institute.
That puts Ontario in the 90th percentile for IBD prevalence in the world.
The study in Inflammatory Bowel Diseases is the first and largest Canadian study of IBD – including Crohn's disease and ulcerative colitis ─ to demonstrate trends in incidence over time, and the first to review the rate of IBD in different age groups.

We’re getting more stupid. That’s one point made in a recent article in the New Scientist, reporting on a gradual decline in IQs in developed countries such as the UK, Australia and the Netherlands. Such research feeds into a long-held fascination with testing human intelligence. Yet such debates are too focused on IQ as a life-long trait that can’t be changed. Other research is beginning to show the opposite.-->
Here is something counter-intuitive: researchers have developed a new quantum imaging technique in which the image has been obtained without ever detecting the light that was used to illuminate the imaged object, while the light revealing the image never touches the imaged object.
As everyone knows, outside the world of quantum mechanics, to obtain an image of an object one has to illuminate it with a light beam and use a camera to sense the light that is either scattered or transmitted through that object. The type of light used to shine onto the object depends on the properties that one would like to image. Unfortunately, in many practical situations the ideal type of light for the illumination of the object is one for which cameras do not exist.
People aged 70 and over who identify themselves as 'old' feel worse about their own health in societies where they perceive they have lower value than younger age groups.
New research from psychologists at the University of Kent, titled 'Being old and ill' across different countries: social status, age identification and older people's subjective health, used data from the European Social Survey. Respondents, who were all aged 70 and over, were asked to self-rate their health.
Researchers at Rice University have synthesized a recently discovered natural fungus-derived antibiotic, viridicatumtoxin B, which may shelp bolster the fight against bacteria that evolve resistance to treatments in hospitals and clinics around the world.
The work reported this month in the Journal of the American Chemical Society (JACS) focused on a tetracycline discovered in 2008 by scientists who isolated small amounts from penicillium fungi. The yield wasn't nearly enough for extensive testing, but it provided a basis for the discoverers to analyze its structure through magnetic resonance imaging.
In 1934, American archaeologist Nelson Glueck named one of the largest known copper production sites of the Levant, located deep in Israel's Arava Valley, "Slaves' Hill."
This hilltop station seemed to bear all the marks of an Iron Age slave camp – fiery furnaces, harsh desert conditions, and a massive barrier preventing escape, but new evidence uncovered by Tel Aviv University archaeologists overturns that narrative and says the people there were instead highly regarded craftsmen rather than slaves.
It has been almost 400 years since the publication of Exercitatio anatomica de motu cordis et sanguinis in animalibus ("On The Motion Of The Heart And Blood In Animals") by the British physician William Harvey, which accurately described the circulation of the blood around the body, and we are still discovering the secrets of the circulatory system and its contents.
This is especially relevant when leveraging the circulatory system’s contents for clinical applications, such as prenatal testing.
Human articular cartilage defects can be treated with nasal septum cells because they are able to adapt to the environment of the knee joint and can thus repair articular cartilage defects.
The nasal cartilage cells' ability to self-renew and adapt to the joint environment is associated with the expression of so-called HOX genes. The scientific journal Science Translational Medicine has published the research results together with the report of the first treated patients.

A piece of the galaxy formation puzzle may have fallen into place, thanks to a team of European and American astronomers peering into the depths of our early universe.-->
Astronomers have caught a glimpse of the earliest stages of massive galaxy construction - a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate.
A fully developed elliptical galaxy is a gas-deficient gathering of ancient stars theorized to develop from the inside out, with a compact core marking its beginnings. Because the galactic core is so far away, the light of the forming galaxy that is observable from Earth was actually created 11 billion years ago, just 3 billion years after the Big Bang.

“The best thing you could do for the Amazon is to blow up all the roads.” These might sound like the words of an eco-terrorist, but it’s actually a direct quote from Professor Eneas Salati, a forest climatologist and one of Brazil’s most respected scientists.-->
Xenon gas is commonly used for diagnostic inhalation because of its anesthetic properties but more recently it has been used by the Russians to cheat in the Olympics, and the cycling community has followed suit, because of its EPO - Erythropoietin - hormone producton ability.
It may also be a treatment for post-traumatic stress disorder (PTSD) and other memory-related disorders, according to a new paper in PLOS One.
A Middle Bronze Age Canaanite palace at the Tel Kabri excavation in Israel has revealed an ancient wine cellar.
Functional magnetic resonance imaging (fMRI) has led University of Illinois at Chicago scholars to conclude that young adults who previously experienced the mental illness have hyper-connected emotional and cognitive networks in the brain.
The college students were ages 18 to 23 while they were in a resting state. 30 un-medicated young adults who claimed to have experienced depression and 23 healthy controls were used in the study, which has published in PLOS ONE.
"We wanted to see if the individuals who have had depression during their adolescence were different from their healthy peers," said Rachel Jacobs, assistant professor in psychiatry and lead author of the study.
Not all students returning to school this month will be up to date on their vaccinations and a new paper in Gender&Society by Jennifer Reich,a professor of Sociology from the University of Colorado Denver, correlates it to the class privilege of their mothers.
Where should we go, on Mars, to look for droplets and streaks of present day liquid water? You may have heard of the "warm seasonal flows", and the recent "swimming pools of bacteria".
However, there are several other promising ideas for habitats such as the "Flow like features", the advancing sand dunes bioreactor, and possibilities for life using the humidity of the night time air on Mars. It's an exciting field with many new discoveries and ideas every year, and it is hard to keep up with the developments.-->
