Sugary drinks linked to earlier onset of menstrual periods
Girls who frequently consume sugary drinks tend to start their menstrual periods earlier than girls who do not, according to new research. The findings are important not only because of the growing problem of childhood obesity in a number of developed countries, but also because starting periods earlier is linked to an increased risk of breast cancer later in life.

Infant failure to thrive linked to lysosome dysfunction
Neonatal intestinal disorders that prevent infants from getting the nutrients they need may be caused by defects in the lysosomal system -- or cell recycling center -- that occur before weaning. Scientists provide a new target for research and future therapies to help infants unable to absorb milk nutrients and gain weight.

That's using your head: Brain regulates fat metabolism, potentially stopping disease
Atherosclerosis -- hardening and narrowing of the arteries -- can be caused by fat build up that causes plaque deposits, and is one of the main causes of cardiovascular disease. Now a researcher has shown a link between how the brain can regulate fat metabolism, potentially stopping the development of this disease risk factor in obesity and diabetes.

Targeted MRI/ultrasound beats standard biopsy to detect high-risk prostate cancer
Targeted biopsy using new fusion technology that combines magnetic resonance imaging (MRI) with ultrasound is more effective than standard biopsy in detecting high-risk prostate cancer, according to a large-scale study.

Brain region vulnerable to aging is larger in those with longevity gene variant
People who carry a variant of a gene that is associated with longevity also have larger volumes in a front part of the brain involved in planning and decision-making, according to researchers.

Inherited gene variation helps explain drug toxicity in patients of East Asian ancestry
About 10 percent of young leukemia patients of East Asian ancestry inherit a gene variation that is associated with reduced tolerance of a drug that is indispensable for curing acute lymphoblastic leukemia, the most common childhood cancer, scientists report.

Unlocking the kidney riddle in newborns
Researchers are closer to understanding why babies born with smaller kidneys have a high risk of developing cardiovascular disease. Currently, renal disorders at birth affect about one in 500 babies. Many of these babies go on to lead healthy normal lives, however 20-40 per cent will develop chronic kidney disease and high blood pressure. Unfortunately, these conditions are the main cause of end-stage kidney disease and the need for dialysis in children.

Negative patient-doctor communication could worsen symptoms
A type of 'nocebo' response -- where patients perceive a lack of understanding or acceptance from their doctor -- could create anger and distress, physiological conditions that could worsen illness, a new research shows.

Salivary biomarkers predict oral feeding readiness in preterm newborns
Results from a new study hold the potential to substantially improve clinical decision-making to determine when a premature newborn is ready for oral feeding. The study describes developmental salivary biomarkers associated with feeding success in newborns, markers that could lead to development of objective assessment tools for caregivers.

Neuroscience researchers believe in quitting smoking gradually
The immediate reaction in the brain after quitting smoking has been the focus of a recent study. At just 12 hours after kicking the habit, the oxygen uptake and blood flow in the brain decrease significantly compared to never-smokers. This could explain why it is so difficult to say goodbye to nicotine once and for all, the researchers say.
