World’s First Publicly Funded Spinal Cord Stimulation Pilot Study Supports Feasibility of a Full Clinical Trial in Refractory Angina Pectoris

Researchers funded by the National Institute for Health Research to conduct a multi-center pilot study of spinal cord stimulation (SCS) in refractory chronic angina pectoris will advise NICE that a fully powered nationwide study is feasible, with SCS therapy and trial outcome measures shown to be acceptable and appropriate for future randomized controlled trials.

Eating Less During Late Night Hours May Stave off Some Effects of Sleep Deprivation

Eating less late at night may help curb the concentration and alertness deficits that accompany sleep deprivation, according to results of a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania that will be presented at SLEEP 2015, the 29th annual meeting of the Associated Professional Sleep Societies LLC.

Integrating Locally Produced Energy Using Microgrids

Strategic use of locally produced, renewable energy through smart microgrids can reduce power costs and help prevent outages. Assistant professors Wei Sun and Reinaldo Tonkoski of the South Dakota State University Electrical Engineering and Computer Science Department are developing the smart power management technologies that will make it possible for communities and businesses to use locally produced wind and solar energy yet maintain a consistent, reliable power system. The automated system will also facilitate development of a self-healing smart grid that can help prevent power outages.

Research Shows Wastewater Treatment May Be Creating New Antibiotics

For years scientists have been aware of the potential problems of antibiotics being present in wastewater, and the research of engineering professor Olya Keen is showing that treatments to clean wastewater may actually be creating new antibiotics and further contributing to the development of antibiotic resistance in the environment.

New Computational Technique Advances Color 3D Printing Process

Columbia Engineering professor Changxi Zheng has developed a technique that enables hydrographic printing, a widely used industrial method for transferring color inks on a thin film to the surface of 3D objects, to color these surfaces with the most precise alignment ever attained. His new computational method, which simulates the printing process and predicts color film distortion during hydrographic immersion, generates a colored film that guarantees exact alignment of the surface textures to the object.

From Reverberating Chaos to Concert Halls, Good Acoustics is Culturally Subjective

Play a flute in Carnegie Hall, and the tone will resonate and fill the space. Play that same flute in the Grand Canyon, and the sound waves will crash against the rock walls, folding back in sonic chaos. The disparity is clear – to the modern listener, the instrument belongs in an auditorium. "Distinct echoes would be totally unforgivable in today's performance spaces," says Steven J. Waller, an archaeo-acoustician. “But, in the past, people sought echoes."

All Sounds Made Equal in Melancholy

Psychoacoustics identifies five basic types of emotional speech: angry, fearful, happy, sad and neutral. In order to fully understand what’s happening with speech perception, a research team at the University of Texas at Austin studied how depressed individuals perceive these different kinds of emotional speech in multi-tonal environments. They will present their findings at the 169th ASA meeting, held this week in Pittsburgh.
