Feeling blue and seeing blue: Sadness may impair color perception

by Dr. Jekyll in Lunatic Laboratories

The world might seem a little grayer than usual when we’re down in the dumps and we often talk about “feeling blue” — new research suggests that the associations we make between emotion and color go beyond mere metaphor. The results of two studies indicate that feeling sadness may actually change how we perceive color. Specifically, researchers found that participants who were induced to feel sad were less accurate in identifying colors on the blue-yellow axis than those who were led to ........ Read more »

The alien within: Fetal cells influence maternal health during pregnancy (and long after)

by Dr. Jekyll in Lunatic Laboratories

Parents go to great lengths to ensure the health and well-being of their developing offspring. The favor, however, may not always be returned. Dramatic research has shown that during pregnancy, cells of the fetus often migrate through the placenta, taking up residence in many areas of the mother’s body, where their influence may benefit or undermine maternal health....

Confidence in parenting could help break cycle of abuse

by Dr. Jekyll in Lunatic Laboratories

To understand how confidence in parenting may predict parenting behaviors in women who were abused as children, psychologists have found that mothers who experienced more types of maltreatment as children are more critical of their ability to parent successfully. Intervention programs for moms at-risk, therefore, should focus on bolstering mothers’ self-confidence–not just teach parenting skills, the researchers said.... Read more »

HIV particles do not cause AIDS, our own immune cells do

by Dr. Jekyll in Lunatic Laboratories

Researchers have revealed that HIV does not cause AIDS by the virus’s direct effect on the host’s immune cells, but rather through the cells’ lethal influence on one another. HIV can either be spread through free-floating virus that directly infect the host immune cells or an infected cell can pass the virus to an uninfected cell.... Read more »

Don’t know what “jurisdictional error” means? Some people’s future depends on it

by Laura Smith-Khan in Language on the Move

When people arrive in countries like Australia, seeking to be recognised as refugees and offered protection, it is obviously important that they are able to communicate their experiences and respond to any doubts the authorities may have about their claims. … Continue reading →... Read more »

Men And Women: Similarities Or Differences?

by Alexis Delanoir in How to Paint Your Panda

It's a question that many people struggle with and has great implications for the study of our species: are men and women more alike than different or more different than alike, and what differences exist between the sexes?... Read more »

Want a better relationship and a better sex life?

by Dr. Jekyll in Lunatic Laboratories

If men take up more of the child-care duties, splitting them equally with their female partners, heterosexual couples have more satisfaction with their relationships and their sex lives, according to new research by sociologists. The group used data from more than 900 heterosexual couples’ responses in the 2006 Marital Relationship Study (MARS).... Read more »

Easter Eggs from Raymond Dart

by zacharoo in Lawn Chair Anthropology

Some of the more colorful ideas and text in the anthropological literature are courtesy of Raymond Dart. In 1925, Dart identified the Taung fossil as a close relative of humans, and coined the scientific name, Australopithecus africanus. This was a pretty good idea, as Taung was the first in what is now a large collection of fossils attributed to this […]... Read more »

How long have primates been infected with viruses related to HIV?

by Dr. Jekyll in Lunatic Laboratories

Disease-causing viruses engage their hosts in ongoing arms races: positive selection for antiviral genes increases host fitness and survival, and viruses in turn select for mutations that counteract the antiviral host factors. Studying such adaptive mutations can provide insights into the distant history of host-virus interactions. A study of antiviral gene sequences in African monkeys suggests that lentiviruses closely related to HIV have infected primates in Africa as far back as 16 million ye........ Read more »

The Myth of Beer Goggles?

by Neuroskeptic in Neuroskeptic_Discover

A new study casts doubt on the idea that alcohol causes people to seem more attractive - the famous "beer goggles" effect.



Psychologists Olivia Maynard and colleauges, of Bristol, UK, conducted an unusual "real world" experiment.  Rather than doing their testing in the laboratory, they went into three Bristol pubs in the evening (5-11 pm) and recruited volunteers on the spot. With a total sample size of 311, it was a very large sample.

Each participant was breathalyzed to estimate thei... Read more »

Happiness spreads, but depression isn’t contagious

by Dr. Jekyll in Lunatic Laboratories

Having friends who suffer from depression doesn’t affect the mental health of others, according to research. The team found that having friends can help teenagers recover from depression or even avoid becoming depressed in the first instance. The findings are the result of a study of the way teenagers in a group of US high schools influenced each others’ mood. The academics used a mathematical model to establish if depression spreads from friend to friend.... Read more »

How influential are peer reactions to posts on Facebook news channels?

by Dr. Jekyll in Lunatic Laboratories

An experiment to determine the effects of positive and negative user comments to items posted by media organizations on Facebook news channels showed, surprisingly, that the influence of user comments varied depending on the type and number of user comments. Negative comments influenced the persuasiveness of a news article, while positive comments did not, and a high number of likes did not have the expected bandwagon effect.... Read more »

Review of the pertinent literature showed that sleep may be the dominant factor in fatigue in MS. This was also the finding in Dr. Strober’s study of 107 employed individuals with MS of whom 61% reported poor sleep.... Read more »

The stomach is the way to a woman’s heart, too

by Dr. Jekyll in Lunatic Laboratories

You've heard that romance starts in the kitchen and not in the bedroom. Well, researchers at Drexel University finally have the science to support that saying - but not the way you might think. Researchers found that women's brains respond more to romantic cues on a full stomach than an empty one. The study explored brain circuitry in hungry versus satiated states among women who were past-dieters and those who had never dieted.... Read more »
