In a study published online in the journal Neuropsychopharmacology, scientists from the Indiana University School of Medicine say the taste of beer alone triggers a release of dopamine, the brain’s chemical reward signal.
Women better off without bras, claims professor Jean-Denis Rouillon, from the University of Besançon in eastern France. Wearing a bra does nothing to reduce back pain, and the chest supports actually cause increased breast sagging.
Through history, some have concluded that a pessimistic attitude, although justified, must be avoided. Worrying takes years off your life, right? Well, maybe not. Pessimists rejoice: happy-go-lucky, care-free peers of yours probably won’t live as long as you. New research suggests that the pessimists wind up outlasting the optimists.
Some musicians and composers have a brain disorder that allows them to “see” music as colors or shapes. This sensory disorder is called synesthesia. Mozart is said to have had this condition. He said that the key of D major had a warm “orangey” sound to it, while B-flat minor was blackish. A major was a rainbow of colors to him. This may explain why he wrote some of his music using different colors for different music notes, and why much of his music is in major keys.
Grapefruit juice can cause severe side effects (including sudden death) when taken with certain common medications. Many of the drugs are common, such as some cholesterol-lowering statins, antibiotics and calcium channel blockers used to treat high blood pressure. Others include agents used to fight cancer or suppress the immune system in people who have received an organ transplant.
Researchers in Finland have found that having a boy, historically speaking, shortens a mother’s life expectancy by a statistically significant amount. Their study, which looked at Finnish villagers in pre-industrial Scandinavia, showed that a woman’s risk of death increased by seven percent per year for each son born. By investigating parish records for individuals in eight parishes who lived during the seventeenth to mid-twentieth centuries, “they found that if a woman in these communities was 37 years old at the time of having her last child, her life expectancy would vary depending on the sex of her children.”
Now there’s another reason to love horror flicks — scientists say we can burn calories as we watch. A new study has revealed that watching scary movies can burn up to 200 calories a sitting. The adrenaline rushes that viewers experience during a 90-minute horror film are believed to use up the same amount of energy as is contained within a bar of chocolate.
A study at Swinburne University in Melbourne gave 40 participants the Defined Intensity Stressor Simulation — a battery of concurrent tests that appear on a screen, all at once, designed both to induce stress and to measure subject performance.
New research has determined that a judgmental attitude may just go hand in hand with exposure to organic foods. In fact, a new study published in the journal of Social Psychological and Personality Science, has found that organic food may just make people act a bit like jerks.
