Tormented water masses with distant horizons in flames. Multicoloured reflexions over living oceans. Moving images with an astounding visual impact. These are the first words that come to my mind if I try to describe Paola Nicoletti's paintings. Needless to say, I like them a lot - but judge for yourself from the three images below, or by visiting her web site. And if you do, please drop her a line!Paola is a friend, who has recently taken her painting quite seriously. I believe these pictures give ample justification for it. Here is what Paola herself writes to describe some of her works:

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…
San Diego, CA, March 17, 2009 – The benefits of moderate physical activity to general health and well-being are well known. It is recommended that people engage in 150 minutes per week of moderate intensity physical activity, equivalent to 30 minutes each day 5 times a week. Although pedometers are widely used as a physical activity monitoring tool, they are unable to measure activity intensity. Researchers have determined that a rate of at least 100 steps per minute achieves moderate intensity activity. Therefore a simple pedometer-based recommendation of 3000 steps in 30 minutes can get…
DURHAM, N.C. -- A Duke University professor and his graduate student have discovered a universal principle that unites the curious interplay of light and shadow on the surface of your morning coffee with the way gravity magnifies and distorts light from distant galaxies.
They think scientists will be able to use violations of this principle to map unseen clumps of dark matter in the universe.
Light rays naturally reflect off a curve like the inside surface of a coffee cup in a curving, ivy leaf pattern that comes to a point in the center and is brightest along its edge.
Mathematicians and…
We've heard it before: "Imagine yourself passing the exam or scoring a goal and it will happen." We may roll our eyes and think that's easier said than done, but in a new study in Psychological Science, a journal of the Association for Psychological Science, psychologists Christopher Davoli and Richard Abrams from Washington University suggest that the imagination may be more effective than we think in helping us reach our goals.
A group of students searched visual displays for specific letters (which were scattered among other letters serving as distractors) and identified them as quickly as…
WEST LAFAYETTE, Ind. - Roundup Ready crops have made weed control much easier for farmers, but a new study shows their reliance on the technology may be weakening the herbicide's ability to control weeds.
Bill Johnson, a Purdue University associate professor of weed science, said farmers who plant Roundup Ready crops and spray Roundup or glyphosate-based herbicides almost exclusively are finding that weeds have developed resistance. It is only a matter of time, Johnson said, before there are so many resistant weeds that the use of glyphosate products would become much less effective in some…
Researchers at the Oregon Health & Science University School of Dentistry (www.ohsu.edu/sod) have found the majority of patients with self-ligating orthodontic brackets retain fewer bacteria in plaque than patients with elastomeric orthodontic brackets. The OHSU team also found that a biochemical technique measuring ATP- (adenosine triphosphate-) driven bioluminescence could be a useful chair-side tool in the rapid quantification of oral bacteria and in the assessment of oral hygiene during orthodontic treatment.
The findings are published in the April 2009 issue of the American Journal…
Scientists have long been interested in the interplay of emotions and identity, and some have recently focused on cultural identity. One's heritage would seem to be especially stable and impervious to change, simply because it's been passed down generation after generation and is deeply ingrained in the collective psyche. But how deeply, exactly? Psychologists Claire Ashton-James of the University of British Columbia, William W. Maddux from INSEAD, Adam Galinsky of Northwestern University, and Tanya Chartrand from Duke University decided to explore this intriguing question in the laboratory,…
NEW BRUNSWICK, N.J. – Rutgers' Food Policy Institute (FPI) released a study today showing that many Americans fail to check their homes for recalled food products. Only about 60 percent of the studied sample reported ever having looked for recalled food in their homes, and only 10 percent said they had ever found a recalled food product.
The study was based on a survey of 1,101 Americans interviewed by telephone from Aug. 4 to Sept. 24, 2008. The study can be downloaded at www.foodpolicy.rutgers.edu.
Most respondents said they pay a great deal of attention to food recalls and, when they learn…
For the first time, scientists have isolated the parasite Nosema ceranae (Microsporidia) from professional apiaries suffering from honey bee colony depopulation syndrome. They then went on to treat the infection with complete success.
In a study published in the new journal from the Society for Applied Microbiology: Environmental Microbiology Reports, scientists from Spain analysed two apiaries and found evidence of honey bee colony depopulation syndrome (also known as colony collapse disorder in the USA). They found no evidence of any other cause of the disease (such as the Varroa destructor…
