Recipe for antibacterial plastic: Plastic plus egg whites
Bioplastics made from protein sources such as albumin and whey have shown significant antibacterial properties, findings that could eventually lead to their use in plastics used in medical applications such as wound healing dressings, sutures, catheter tubes and drug delivery, according to a recent study. The bioplastic materials could also be used for food packaging.

Study provides evidence against the fetal origins of cancer, cardiovascular disease
A study evaluated the relationship between nutritional conditions in early life and adult health, and found that famine exposure during the first pregnancy trimester was associated with increases in mortality from causes other than cancer or cardiovascular disease. This is the first study to quantify the possible long-term effects of nutrition deprivation at different stages of pregnancy and long-term mortality.

Long-standing mystery in membrane traffic solved
In 2013, James E. Rothman, Randy W. Schekman, and Thomas C. Südhof won the Nobel Prize in Physiology or Medicine for their discoveries of molecular machineries for vesicle trafficking, a major transport system in cells for maintaining cellular processes. SNARE proteins are known as the minimal machinery for membrane fusion. Scientists now report that NSF/?-SNAP disassemble a single SNARE complex using various single-molecule biophysical methods that allow them to monitor and manipulate individual protein complexes.

Color of lettuce determines the speed of its antioxidant effect
Lettuce, one of the indispensable vegetables in the Mediterranean diet, is a food that greatly benefits health, mainly because it is rich in antioxidants. But not all lettuce varieties have the same antioxidant effect. The color of the leaves of these vegetables determines the speed at which their compounds act. So lettuces with green leaves have antioxidants that react more slowly while red-leaf ones have a faster effect.

How body's good fat tissue communicates with brain
Brown fat tissue, the body’s “good fat,” communicates with the brain through sensory nerves, possibly sharing information that is important for fighting human obesity, such as how much fat we have and how much fat we’ve lost, according to researchers.

Smaller plates, smaller portions? Not always
It may have become conventional wisdom that you can trick yourself into eating less if you use a smaller plate. But a new study finds that trick doesn't work for everyone, particularly overweight teens.
