Abnormal neural activity linked to schizophreniaNeuroscientists have discovered abnormal neural activity in the brain that may cause people with schizophrenia to experience unorganized thought processes, according to a study published in the journal Neuron. Researchers from the Massachusetts Institute of Technology (MIT), led by Susumu Tonegawa, conducted a mouse study in which they found that mice lacking a brain protein called calcineurin experienced hyperactive brain-wave oscillations in the hippocampus when resting...
How healthy is housework?We are constantly reminded that regular physical activity can lead to long-term health benefits and that any activity is better than none, but when it comes to housework, it seems we all need to work harder to make it count as a workout. Both the US Department of Health and Human Services and the UK's NHS guidelines recommend adults take at least 150 minutes of moderate intensity physical exercise each week. They also advise that everyone should include muscle strengthening exercises involving all the major muscle groups...
The NICU environment: Not all silence is goldenMedical technology has improved the survival rates of premature infants, but adverse developmental outcomes are a continuing problem. Researchers have turned their attention to the neonatal intensive care unit (NICU), where premature infants spend their first few weeks or months, for potential answers. In a new study scheduled for publication in The Journal of Pediatrics, researchers studied the relationship between different room types in the NICU and the developmental outcomes of the children at 2 years of age...
What is anorexia nervosa?Anorexia nervosa is a potentially life-threatening eating disorder. It is a serious psychological disorder characterized by either a significantly reduced appetite or complete aversion to eating. A patient with anorexia nervosa, often just called "anorexia" (although the meaning is different), has a distorted body image and an exaggerated fear of becoming overweight or obese - so a deliberate effort is made to lose weight...
Healthier diets possible in low-income, rural communities in AmericaIn the United States, children don't eat enough fruits, vegetables and whole grains. Instead, their diets typically include excessive amounts of sugars and solid fats, counter to the 2010 Dietary Guidelines for Americans recommendations, increasing the risk of obesity and diabetes. A team of investigators implemented a two-year intervention study in low-income, rural areas where a disproportionately higher risk of overweight and obesity habits among children persists, leading to increased risk of diabetes and heart disease in adulthood...
