Housewives are more ecologically aware and recycle more than university students
Dec 27, 2007

Research carried out in the Department of Social Psychology and Methodology of Behaviour Sciences of the University of Granada has shown that the level of academic training is not related to the ecological awareness of people, despite the great proliferation of programs designed to educate and increase social awareness of the environment. Thus, according to research, housewives are more ecologically aware than university students, given they are more willing to recycle glass.

Subliminal messages can influence us in surprising ways - Exposure to national flag brings political moderation
Dec 27, 2007

Flag waving is a metaphor for stirring up the public towards adopting a more nationalistic, generally hard-line stance. Indeed, "rally 'round the flag" is a venerable expression of this phenomenon.

It comes as some surprise, then, that studies conducted by researchers at the Hebrew University of Jerusalem have shown that exposing people to a subliminal image of the national flag had just the opposite fact -- moderating their political attitudes.

Dec 27, 2007

Scientists have for the first time identified brain sites that fire up more when people make impulsive decisions. In a study comparing brain activity of sober alcoholics and non-addicted people making financial decisions, the group of sober alcoholics showed significantly more "impulsive" neural activity.

Poor Americans in the United States suffer hidden burden of parasitic and other neglected diseases
Dec 26, 2007

In an article entitled "Poverty and Neglected Diseases in the 'Other' America," Professor Peter Hotez (George Washington University and the Sabin Vaccine Institute) says that there is evidence that the parasitic diseases toxocariasis, cysticercosis and toxoplasmosis as well as other neglected infections are very common in the United States, especially among poor and underrepresented minority populations living in inner cities and poor rural areas.

Photo-monitoring whale sharks
Dec 26, 2007

Listed as a rare species, relatively little is known about whale sharks, which live in tropical and warm seas, including the western Atlantic and southern Pacific.

However, a new study combines computer-assisted photographic identification with ecotourism to study the rare species and suggests whale shark populations in Ningaloo, Western Australia are healthy.

1 person out of every 1,000 has synaesthesia, in which an individual can smell a sound
Dec 26, 2007

Surprising as it may seem, there are people who can smell sounds, see smells or hear colours. Actually, all of as, at some point in our lives, have had this skill (some authors affirm that it is common in newborns). This phenomenon, called "synaesthesia" - from the Greek "syn" (with) and "aisthesis" (sensation) - consists of the pairing of two bodily senses by which the perception of a determined stimulus activates a different subjective perception with no external stimulus (in science, the evoker stimulus is called inducer and the additional experience concurrent).

Can massage chairs or a vibrating mouse prevent computer-related injuries?
Dec 25, 2007

A chair that undulates, a mouse that vibrates, a monitor suspended over a desk on a movable arm. These are some of the kinds of newfangled ergonomic products that Alan Hedge, international authority on office ergonomics, studies to see if they can prevent repetitive motion injuries among the estimated 100 million people who now use computers in the United States.

Finding Makes TIME Magazine's Top 10 Scientific Discoveries of 2007
Dec 25, 2007

The December 24 issue of TIME Magazine selected to its list of "Top 10 Scientific Discoveries in 2007" the findings of a Stony Brook University-led team of international scientists that used a sophisticated method to accurately date a human skull found in South Africa in 1952. The discovery was first reported in the January 12, 2007 issue of Science by Principal investigator Frederick E. Grine, Ph.D., Professor of Anthropology and Anatomical Sciences at Stony Brook University, and colleagues, and provides critical evidence that supports the theory that modern man originated in sub-Saharan Africa.

Youngsters Prefer a Home Like Mom's
Dec 24, 2007

When young mice leave their mothers' homes, they choose to live in places much like the ones where they were raised, according to research done at UC Davis.

It may not sound surprising, but it is actually a revelation for biologists trying to save endangered wildlife, who have largely assumed that when it comes to habitat preferences, one size fits all for the individuals in a given species.

Where and why humans made skates out of animal bones
Dec 24, 2007

Archaeological evidence shows that bone skates (skates made of animal bones) are the oldest human powered means of transport, dating back to 3000 BC. Why people started skating on ice and where is not as clear, since ancient remains were found in several locations spread across Central and North Europe.
