Is it possible to scientifically measure someone’s sense of humor? Are there universally good or bad jokes that make people laugh no matter their gender, profession or cultural background? These are some of the questions answered by the doctoral thesis Sentido del humor: construcción de la escala de apreciación del humor (Sense of humor: building of the appreciation of humor scale), carried out by Hugo Carretero Dios, researcher in the department of Social Psychology and Methodology of Behavioural Science at the University of Granada. A whole generation of Americans thought Red Skelton was…

Yes, you secretly like giving your money to the government. University of Oregon scientists have found that doing things like donating money to charity or even paying your taxes can give you the same sort of satisfaction you derive from feeding your own hunger pangs. A cognitive psychologist and two economists gave 19 female participants $100 and then scanned their brains with functional magnetic resonance imaging (fMRI) as they watched their money go to the food bank through mandatory taxation, and as they made choices about whether to give more money voluntarily or keep it for themselves…

"Innovative" science classes - new ways of teaching that are interactive, non-boring and therefore in defiance of every method that made America the home of great scientists for 150 years, are all the rage. The goal is to get more women in science, more minorities in science, more everyone in science. It may not be working, and it may even make things worse, says a study the University of Colorado at Boulder. The researchers looked at interactive teaching methods, which can include online homework systems, help-room sessions, student discussions, and other methods that were not part of…

A major study of the organization and regulation of the human genome published today changes our concept of how our genome works. The integrated study is an exhaustive analysis of 1% of the genome that, for the first time, gives an extensive view of genetic activity alongside the cellular machinery that allows DNA to be read and replicated. The lead report from the ENCyclopedia Of DNA Elements (ENCODE) Consortium, published in Nature, together with 28 companion papers published in Genome Research, defined in detail which regions of the genome are actively copied in the cell, revealed the…

Why do some online communities succeed, like Second Life, Facebook and, well, this one, and some fail? The answer may be in what their communities think about 'giving' and it can tell us a lot about people in general. Everyone does something on social sites for a reason. People like to 'get paid' even if that doesn't mean money. It is why people submit articles to Digg - submitters get the satisfaction of knowing they brought an interesting article to people that they may not have found themselves. Or, in the case of Newsvine, they may literally be getting paid to write interesting…

Human interaction and stimulation enhance chimpanzees’ cognitive abilities, according to new research from the Chimpanzee Cognition Center at The Ohio State University. The study (1) is the first to demonstrate that raising chimpanzees in a human cultural environment enhances their cognitive abilities, as measured by their ability to understand how tools work. The scientists compared three groups of chimpanzees: one with a history of long-term stable, social interaction with humans (‘enculturated’); a group raised in a sanctuary setting, with only caretaker contact with humans (‘semi-…

While solar power and hybrid cars have become popular symbols of green technology, Stanford researchers are exploring another path for cutting emissions of carbon dioxide, the leading greenhouse gas that causes global warming. Carbon capture and storage, also called carbon sequestration, traps carbon dioxide after it is produced and injects it underground. The gas never enters the atmosphere. The practice could transform heavy carbon spewers, such as coal power plants, into relatively clean machines with regard to global warming. ''The notion is that the sooner we wean ourselves off fossil…

Rome's Mayor Walter Veltroni will officiate at the first public viewing of "Rome Reborn 1.0," a 10-year project based at the University of Virginia and begun at UCLA to use advanced technology to digitally rebuild ancient Rome. “Rome Reborn 1.0" shows almost the entire city within the 13-mile-long Aurelian Walls as it appeared in A.D. 320. At that time Rome was the multicultural capital of the western world and had reached the peak of its development with an estimated population of one million. Digital video of the Colosseum. Copyright University of Virgina 2007 "Rome Reborn 1.0" is a true…

The potential for gun shows to serve as places where criminals obtain firearms can be curbed through increased regulation without adversely affecting attendance or business, according to a new study. The study, based on field observations made by Garen J. Wintemute, director of UC Davis’ Violence Prevention Research Program, also found that undocumented gun sales between private parties and illegal “straw purchases” in which a person with a clean record buys a weapon for someone with a criminal record were much more common at gun shows in states with little regulation. The take-home message…

The same genetic defect that causes a rare respiratory disease may also lead to some types of congenital heart disease, according to a new study from the University of North Carolina at Chapel Hill School of Medicine. The link between the two diseases starts with cilia, the tiny, hair-like extensions that help the lungs clear of mucus and remove contaminants such as dust. The researchers first noticed the connection in children with a respiratory disease that affects cilia, primary ciliary dyskinesia (PCD). A genetic mutation that impairs cilia movement causes the disease. A few children…
