    Boa Constrictors Kill by Constricting Blood Flow: Study WEDNESDAY, July 22, 2015 (HealthDay News) -- Boa constrictors kill their prey by constricting their blood flow, not by suffocation, a new study shows. The study, published July 22 in the Journal of Experimental Biology , challenges the long-held belief that constrictors kill their prey through suffocation. As the snakes squeeze their victim, blood supply to the heart, brain and other vital organs is cut off. The victims become unconscious in a few ...

This causes the heart to beat erratically or to stop beating. As a result, blood isn't pumped throughout ...

    Posted: 07/26/2015

    Better Sleep May Mean Less Chronic Pain FRIDAY, July 17, 2015 (HealthDay News) -- Improving sleep quality might help ease pain among those with osteoarthritis, a new study suggests.

More than half of all people with osteoarthritis have pain during the night. This may lead to broken sleep and frequent shifts between sleep stages. Previous studies have suggested that disrupted sl...

    Beach Sand, Not Water, More Likely to Make You Sick FRIDAY, July 17, 2015 (HealthDay News) -- Heading to the beach this weekend? A new study finds that when it comes to germs, beachgoers may have more to fear from the sand they sit on than the water they swim in. Studies done with water and sand from Hawaiian beaches found a "higher abundance" of bacteria indicating fecal contamination -- bugs such a E. coli, for example -- in the sand than in the water. In fact, "wastewater-contaminated marine beach sa...

  • Banning Soccer 'Headers' Won't Solve Concussion Problem: Study

    Posted: 07/20/2015

    Banning Soccer 'Headers' Won't Solve Concussion Problem: Study MONDAY, July 13, 2015 (HealthDay News) -- While many experts have called for a ban on "heading" the ball in youth soccer because they believe it is a leading cause of concussions, a new study suggests the body contact that often occurs during such play is to blame for most brain injuries. So banning headers among high school players would not reduce concussion rates as much as enforcing existing rules on rough play would, the researchers add...

It has long been reported that breast-feeding is the healthiest option for babies. The study, published in the August issue of Obstetrics & Gynecology , hints at another potential health benefit from breast-feeding. But researchers also stressed that the fin...
