High Vinculin Levels Help Keep Aging Fruit Fly Hearts Young

American Institute of Physics (AIP)

In the heart, aging can disrupt the protein network within muscle cells that move blood around the body. However, a new discovery in how heart muscles maintain their shape in fruit flies sheds light on the crucial relationship between cardiac function, metabolism, and longevity. Researchers have discovered that maintaining high levels of the protein vinculin confers health benefits to fruit flies. Their work, published in APL Bioengineering, shows that fruit flies bred to produce 50 percent more vinculin enjoyed better cardiovascular health and lived a third of their average life span longer.

New Cost-Effective Instrument Measures Molecular Dynamics on a Picosecond Timescale

American Institute of Physics (AIP)

Studying the photochemistry has shown that ultraviolet radiation can set off harmful chemical reactions in the human body and, alternatively, can provide “photo-protection” by dispersing extra energy. To better understand the dynamics of these photochemical processes, a group of scientists irradiated the RNA base uracil with ultraviolet light and documented its behavior on a picosecond timescale. They discuss their work this week in The Journal of Chemical Physics.

Exploding Waves from Colliding Dissipative Pulses

American Institute of Physics (AIP)

The interaction of traveling waves in dissipative systems, physical systems driven by energy dissipation, can yield unexpected and sometimes chaotic results. These waves, known as dissipative pulses are driving experimental studies in a variety of areas that involve matter and energy flows. In the journal Chaos, researchers discuss their work studying collisions between three types of DSs to determine what happens when these traveling waves interact.
