Mathematical equation to predict happiness: Doesn't depend on how well things go, but on whether things are better than expected Posted: 04 Aug 2014 12:14 PM PDT The happiness of over 18,000 people worldwide has been predicted by a mathematical equation, with results showing that moment-to-moment happiness reflects not just how well things are going, but whether things are going better than expected.

Eating baked, broiled fish weekly boosts brain health, study says Posted: 04 Aug 2014 09:33 AM PDT Eating baked or broiled fish once a week is good for the brain, regardless of how much omega-3 fatty acid it contains, according to researchers. The findings add to growing evidence that lifestyle factors contribute to brain health later in life. Scientists estimate that more than 80 million people will have dementia by 2040, which could become a substantial burden to families and drive up health care costs.

Scientists name new species of cetacean: The Australian humpback dolphin Posted: 01 Aug 2014 09:50 AM PDT Scientists examining a taxonomically confused group of marine mammals have officially named a species new to science: the Australian humpback dolphin, Sousa sahulensis.

Nanostructured metal-oxide catalyst efficiently converts carbon dioxide to methanol, a key commodity for chemicals and fuels Posted: 31 Jul 2014 11:54 AM PDT Scientists have discovered a new catalytic system for converting carbon dioxide (CO2) to methanol-a key commodity used to create a wide range of industrial chemicals and fuels. With significantly higher activity than other catalysts now in use, the new system could make it easier to get normally unreactive CO2 to participate in these reactions.

Scientists reproduce evolutionary changes by manipulating embryonic development of mice Posted: 30 Jul 2014 10:32 AM PDT By modifying the embryonic development of mice, scientists have reproduced in the laboratory the changes in teeth shape which, in mammals, took millions of years of evolution to take place.

Birthweight and breastfeeding have implications for children's health decades later Posted: 30 Jul 2014 10:24 AM PDT Young adults who were breastfed for three months or more as babies have a significantly lower risk of chronic inflammation associated with cardiovascular and metabolic diseases, according to new research.

Do women perceive other women in red as more sexually receptive? Posted: 11 Jul 2014 06:21 AM PDT Women are more likely to wear a red shirt when they are expecting to meet an attractive man, relative to an unattractive man or a woman. But do women view other women in red as being more sexually receptive? And would that result in a woman guarding her mate against a woman in red? A study has sought to answer these questions.
