New cost-effective instrument measures molecular dynamics on a picosecond timescale‎

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.

High vinculin levels help keep aging fruit fly hearts young‎

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 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.

Exploding waves from colliding dissipative pulses‎

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.

Close-ups of grain boundaries reveal how sulfur impurities make nickel brittle‎

Engineers have shed new light on a scientific mystery regarding the atomic-level mechanism of the sulfur embrittlement of nickel, a classic problem that has puzzled the scientific community for nearly a century. The discovery also enriches fundamental understanding of general grain boundaries that often control the mechanical and physical properties of polycrystalline materials.

Social isolation: Animals that break away from the pack can influence evolution‎

For some animals -- such as beetles, ants, toads, and primates -- short-term social isolation can be just as vital as social interaction to development and long-term evolution. Evolutionary biologists describe approaches for testing how an animal's isolation might impact natural selection and evolution. This framework can help design more effective breeding, reintroduction, and conservation strategies.

Transmission of specific colors of light over long distances‎

Researchers have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. They explored a new way to select and send light of a specific color using long silicon wires that are several hundred nanometers in diameter and their work enabled a new type of nanoscale ''light switch'' that can turn on and off the transmission of one color of light over very long distances.

How does the sun's rotational cycle influence lightning activity on earth?‎

A collaborative research team has taken the first steps to understanding how the sun's rotational cycle influences lightning activity. They found answers in an unusual source -- diaries dating back to the 1700s.
