In a study of nearly 200 clinically obese, non-diabetic adults, professor Daniela Jakubowicz of Tel Aviv University found that a 600-calorie breakfast that includes dessert as well as proteins and carbohydrates can help dieters lose weight and keep it off over the long term. Her research indicates that such a morning meal staves off cravings and defuses psychological addictions to sweet foods.

Each part of the body has its own nerve cell area in the brain -- we therefore have a map of our bodies in our heads. The functional significance of these maps is largely unclear. What effects they can have is now shown by RUB neuroscientists through reaction time measurements combined with learning experiments and "computational modeling." They have been able to demonstrate that inhibitory influences of neighboring "finger nerve cells" affect the reaction time of a finger.

Brown fat burns calories to generate body heat in rodents and newborn humans. Researchers seeking to combat the obesity epidemic are trying to develop ways to increase the amount of brown fat an adult human has in the hope that this will make them lose weight. New research indicates that hormones produced by the heart can cause regular fat cells from mice and humans to take on characteristics of brown fat cells.

Australian researchers have found evidence that heart failure is associated with a decline in people's mental processes and a loss of grey matter in the brain. These changes can make it more difficult for heart failure patients to remember and carry out instructions such as taking the correct medication at the right times. The study is published in the European Heart Journal.

Whether enlisting the help of a grandmother or a friend or the magic of Cupid, singles long have understood that assistance may be required to meet someone special. Today such help is likely to come from online methods of matchmaking. But online dating, according to new Northwestern University research, depends largely on ineffective algorithms and profiles for finding potential love interests. Mobile dating, the latest iteration in digital dating, however, may hold the most promise.

The first study to check the effects of eating potatoes on blood pressure in humans has concluded that two small helpings of purple potatoes a day decreases blood pressure by about four percent without causing weight gain. In a report in the ACS' Journal of Agricultural and Food Chemistry, the researchers say that decrease, although seemingly small, is sufficient to potentially reduce the risk of several forms of heart disease.

What would happen if an astronaut developed kidney stones during a mission? Space researchers are developing ultrasound technology that uses enhanced imaging capabilities to detect stones and then give a "push" to help the stones pass naturally. This technology could also change the way kidney stones are treated on Earth. The researchers hope to begin clinical trials this summer.

The ideal male contraceptive would be inexpensive, reliable, and reversible. It would need to be long acting but have few side effects. New research published in BioMed Central's open-access journal Reproductive Biology and Endocrinology used commercially available therapeutic ultrasound equipment to reduce sperm counts of male rats to levels which would result in infertility in humans.

Pouring at least one glass of milk each day could not only boost your intake of much-needed key nutrients, but it could also positively impact your brain and mental performance, according to a recent study in the International Dairy Journal. Researchers found that adults with higher intakes of milk and milk products scored significantly higher on memory and other brain function tests than those who drank little to no milk...
