Fat, the bane of many an adult, is precisely what babies born prematurely need to gain weight and grow strong and healthy. Some students at Rice University have invented a device to ensure preemies get enough fat, which has been a challenge.

Babies born more than five or six weeks before their due dates are unable to feed from a bottle or breast because they cannot coordinate sucking, breathing and swallowing. They must be tube-fed milk, but that too presents problems: Some 20 to 50 percent of the fat content in mothers milk clings to the tubing and never reaches the child. Also lost are essential nutrients, including calcium, phosphorus and magnesium, that bind to the fat.

Fat is essential for preemies, but its always been a problem getting it to them, said Mika Tabata, a senior bioengineering student and a member of the design team Nutriflow at Rice. Our task was to figure out a way to increase the amount of fat they receive, which has been difficult.

Other team members are Alexa Juarez, Denizen Kocak and Nathan Liu, also senior bioengineering students, and Jane Jarjour, a senior majoring in biochemistry and cell biology.

Tabata first encountered the problem in 2013 while serving as a summer medical and research training intern at Baylor College of Medicine. There she worked with Steven Abrams, who researches the absorption and metabolism of dietary minerals in infants and children.

We started out just using a stir-bar to mix the fat into the milk, Liu said. That showed a little improvement but not enough. We tried a sort of blender arrangement, but that stirred the milk too much. It was like churning butter.
