Protests couldn't happen without college students, who have plenty of time on their hands, but research carried out at the University of Granada reveals that busy housewives raising future college students are still more willing to separate glass from other garbage than the students themselves.
Awareness of the environment does not translate into ecologically responsible behavior, according to the research carried out in the Department of Social Psychology and Methodology of Behaviour Sciences of the University of Granada.
This research was carried out by doctor María del Carmen Aguilar Luzón under the direction of professor J. Miguel Ángel García Martínez. The environmental behaviour chosen for the study was the separating of glass from other garbage.

An international team of astronomers, led by Professor Svetlana Berdyugina of ETH Zurich’s Institute of Astronomy, has for the first time ever been able to detect and monitor the visible light that is scattered in the atmosphere of an exoplanet.
Employing techniques similar to how Polaroid sunglasses filter away reflected sunlight to reduce glare, the team of scientists were able to extract polarized light to enhance the faint reflected starlight ‘glare’ from an exoplanet. As a result, the scientists could infer the size of its swollen atmosphere. They also directly traced the orbit of the planet, a feat of visualization not possible using indirect methods.

A genetic mutation already known to be more common in Ashkenazi Jewish breast cancer patients is also prevalent in Hispanic and young African-American women with breast cancer, according to one of the largest, multiracial studies of the mutation to date.
Researchers at the Stanford University School of Medicine and the Northern California Cancer Center reported the finding from a study of 3,181 breast cancer patients in Northern California. It revealed that although Ashkenazi Jewish women with breast cancer had the highest rate of the BRCA1 mutation at 8.3 percent, Hispanic women with breast cancer were next most likely, with a rate of 3.5 percent.

People with clinical addictions know first-hand the ravages the disease can take on almost every aspect of their lives. So why do they continue addictive behaviors, even after a period of peaceable abstinence?
Some answers appear rooted in regions of the brain active during decision making.
"It's perhaps not just that people are slaves to pleasure, but that they have trouble thinking through a decision," said Charlotte Boettiger, an assistant professor of psychology at the University of North Carolina at Chapel Hill, and lead author of a study in the December issue of the Journal of Neuroscience that took a novel tack in addiction imaging research.

It's good news that we are living longer, but bad news that the longer we live, the better our odds of developing late-onset Alzheimer's disease.
Alzheimer's is a debilitating neurodegenerative disease that causes memory loss, dementia, personality change and ultimately death. The national Alzheimer's Association estimates that 5.1 million Americans are currently afflicted with the disease and predicts that the number may increase to between 11 million and 16 million people by the year 2050.
Many Alzheimer's researchers have long touted fish oil, by pill or diet, as an accessible and inexpensive "weapon" that may delay or prevent this debilitating disease.

One person out of every thousand has synaesthesia, a psychological phenomenon in which they can smell a sound or hear a color. Most of these people are not aware they are synaesthetes and feel certain about the way they perceive things: they think the way they experience the world is normal. But, when they realize that something is not quite right, they become disappointed.
The research field has grown from grapheme-color synaesthesia to include other forms of synaesthesia in which flavors are evoked by music or words (lexical-gustatory synaesthesia), space structures by time units, colors by music, etc.
Surprising as it may seem, there are people who can smell sounds, see smells or hear colors.

In a late-year flurry, Congress passed many bills last week. Among others, Congress passed an all-in-one spending bill. It combined eleven spending bills and additional spending for the Iraq war into one. H.R. 2764, now called the Consolidated Appropriations Act, 2008, is the bill. Its cost per U.S. family is a little over $9,400, about $720 of which is for the additional military spending.
Most relevant to readers here is P.L. 110-140, The CLEAN Energy Act of 2007.

A unique electron microscope that can help create four-dimensional “movies” of molecules may hold the answers to research questions in a number of fields including chemistry, biology, and physics, according to an article in Chemical & Engineering News.
In the article, C&EN Associate Editor Rachel Petkewich notes that the microscope, located at the California Institute of Technology, is a modified transmission electron microscope interfaced with an ultrafast laser. The ultrafast microscope is the only one capable of capturing four-dimensional pictures of molecules — 3-D structural changes over time — as they form and break apart, the writer states.

Researchers in New Jersey report development of a new type of non-stick material whose ability to shed liquids like water from a duck’s back can be turned on or off simply by flipping an electrical switch.
The material, called “nanonails,” offers a wide-range of potential applications including contamination-resistant and self-cleaning surfaces, reduced-drag ships, and advanced electrical batteries, they say. Their study is scheduled for the Jan. 1 issue of Langmuir.
For years, researchers sought to develop surfaces that repel virtually any liquid. They’ve created non-stick surfaces that repel water and certain other liquids, but have had little success with repelling common organic liquids such as oils, solvents and detergents.

In a finding that defies conventional culinary wisdom, researchers in Italy report that cooking vegetables can preserve or even boost their nutritional value in comparison to their raw counterparts, depending on the cooking method used. Their study is scheduled for the Dec. 26 issue of Journal of Agricultural and Food Chemistry.
Nicoletta Pellegrini and colleagues note that although many people maintain that eating raw vegetables is more nutritious than eating cooked ones, a small but growing number of studies suggest that cooking may actually increase the release of some nutrients.

Scientists have genetically engineered a mosquito to release a sea-cucumber protein into its gut which impairs the development of malaria parasites, according to research in PLoS Pathogens. Researchers say this development is a step towards developing future methods of preventing the transmission of malaria.
Malaria is caused by parasites whose lives begin in the bodies of mosquitoes. When mosquitoes feed on the blood of an infected human, the malaria parasites undergo complex development in the insect’s gut. The new study has focused on disrupting this growth and development with a lethal protein, CEL-III, found in sea cucumbers, to prevent the mosquito from passing on the parasite.

A brain chemical that makes us sleepy also appears to play a central role in the success of deep brain stimulation to ease symptoms in patients with Parkinson’s disease and other brain disorders. The surprising finding is outlined in a paper published in Nature Medicine.
The work shows that adenosine, a brain chemical most widely known as the cause of drowsiness, is central to the effect of deep brain stimulation, or DBS. The technique is used to treat people affected by Parkinson’s disease and who have severe tremor, and it’s also being tested in people who have severe depression or obsessive-compulsive disorder.
