A Ph.D. thesis at the University of the Basque Country has analyzed the role played by a number of emotional variables, such as the way in which negative emotions are controlled or attitudes to emotional expression, and to use these variables as tools to predict the possibility of suffering an eating disorder.

A baffling report says health workers fail to understand the importance of sex for Tanzanian children.   Yes, children.

Community health organizations working on AIDS prevention projects in Tanzania, frequently fail to understand how children in Tanzania deal with sex, says Miranda van Reeuwijk, who followed groups of children in Tanzania between 2004 and 2008.  

van Reeuwijk followed the children in order to help change this situation and says the children mainly view sex as something from which they can personally benefit, but frequently hide their relationships from parents and health workers. They are more scared of their strict parents than of HIV. 

Melatonin can slow down the effects of aging, according to a team at laboratoire Arago in Banyuls sur Mer (CNRS / Université Pierre et Marie Curie) who say that a treatment based on melatonin can delay the first signs of aging in a small mammal.

Better known as the ‘time-keeping' hormone, melatonin is naturally secreted by the body during the night. It is therefore a kind of biological signal for nightfall, allowing an organism to synchronize itself with the day/night rhythm.

The largest artificial underground cav in Israel has been exposed in the Jordan Valley in the course of a survey carried out by the University of Haifa's Department of Archaeology. Prof. Adam Zertal, who headed the excavating team, reckons that this cave was originally a large quarry during the Roman and Byzantine era and was one of its kind. Various engravings were uncovered in the cave, including cross markings, and it is assumed that this could have been an early monastery.

"It is probably the site of "Galgala" from the historical Madaba Map," Prof. Zertal says.

A toxic molecule implicated in cell damage and disease  may also be essential for bird migration, according to the University of Illinois. They propose the molecule superoxide as a key player in the mysterious process that allows birds to 'see' Earth's magnetic field.

Where we are born not only determines how we speak apparently how we taste food and drink, according to Andy Taylor, a researcher in flavor technology at The University of Nottingham and Greg Tucker, a food psychologist.

The taste preferences of the UK's major regions have been analyzed by the pair and Taylor of the Flavour Research Group said, "Taste is determined by our genetic make-up and influenced by our upbringing and experience with flavours. Just as with spoken dialects, where accent is placed on different syllables and vowel formations, people from different regions have developed enhanced sensitivities to certain taste sensation and seek foods that trigger these."
