Tackling a hearty appetite early in life could help prevent obesity in the future…and why football helmets may not be as effective against serious brain injuries as first thought.
Babies with hearty appetites may be more prone to obesity later in life. Researchers in London watched a group of twins for fifteen months. The babies were measured according to how much they ate after they already felt full and how much they ate after seeing or smelling good food. In each case, the twin who had the better appetite ate more, grew faster and weighed more, putting them at greater risk for obesity.

Wearing a football helmet may not protect a child from hits to the side of the head, an often dangerous source of brain injury. Researchers at Florida State University tested ten popular helmets. The study found on average, wearing a helmet reduces the risk of traumatic brain injury by only 20-percent, compared to not wearing a helmet.

Doctors who suspect their patients have lung disease may want to use a high resolution cat scan before resorting to a more invasive biopsy. A University of Washington Medical Center study shows use of the high resolution scan can be effective at detecting a specific pattern on diseased lungs. Surgical biopsy is a riskier procedure and many patients are too sick or old to tolerate it.
