Calyx of Held: The largest synapse could shed light on neuropsychiatric disorders

Humans and most mammals can determine the spatial origin of sounds with remarkable acuity. We use this ability all the time -- crossing the street; locating an invisible ringing cell phone in a cluttered bedroom.

Humans: The primary cause of global climate change

Do most scientists agree that human activity is causing global climate change? Yes, they do, according to an extensive analysis of the abstracts or summaries of scientific papers published over the past 20 years, even though public perception tends to be that climate scientists disagree over the fundamental cause of climate change.

New research reveals how endothelium maintains highly efficient barrier function

The endothelium, the cellular layer lining the body's blood vessels, is extremely resilient. Measuring just a few hundred nanometers in thickness, this super-tenuous structure routinely withstands blood flow, hydrostatic pressure, stretch and tissue compression to create a unique and highly dynamic barrier that maintains the organization necessary to partition tissues from the body's circulatory system.

Protein tumor necrosis factor-alpha is a powerful weapon to control cancer

The protein tumor necrosis factor-alpha (TNF-alpha) is a powerful weapon in the arsenal to control cancer. Unfortunately, as is the case with many potent cancer therapies, the use of TNF-alpha as an anti-cancer therapy has been severely limited.

Metallurgists use microwave oven to produce nanocrystal semiconductors

University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity.

Scientists develop new technique for imaging nanoparticle dynamics with atomic resolution

The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects.

Cell fusion studies at Johns Hopkins could lead to improved treatments for muscular dystrophy

Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some assumed, but, rather, is initiated and driven by one of the fusion partners. The discovery, they say, could lead to improved treatments for muscular dystrophy, since muscle regeneration relies on cell fusion to make muscle fibers that contain hundreds or even thousands of nuclei.
