Using small explosions produced by a mix of methane and oxygen, researchers have designed a soft robot that can leap as much as a foot in the air. That ability to jump could one day prove critical in allowing the robots to avoid obstacles during search and rescue operations following a disaster....

"Good" bacteria that live in our intestines have been linked with a variety of health benefits, from fighting disease to preventing obesity. In a new study medical researchers have discovered another advantage to these friendly microscopic tenants: Chemicals secreted by good bacteria that typically...

A much neglected part of the obesity epidemic is that it has resulted in more overweight/obese women before and during pregnancy. Their offspring also tend to have higher birth weights and more body fat, and carry an increased risk of obesity and chronic diseases later in life. However, the nutritional factors and mechanisms...
