Groundbreaking international legal principles on sexual orientation, gender identity, and international law have been released by 29 international human rights experts, led by University of Nottingham academic, Professor Michael O'Flaherty.

The "Yogyakarta Principles" call for worldwide action against violence, discrimination and abuse, by governments, the UN human rights system, national human rights institutions, non-governmental organisations, and others.

A new technology developed at the University of Toronto is revealing biochemical processes responsible for diseases such as cystic fibrosis and could one day pave the way for pharmaceutical applications.

A remarkable eclipse of a supermassive black hole and the hot gas disk around it has been observed with NASA's Chandra X-ray Observatory. This eclipse has allowed two key predictions about the effects of supermassive black holes to be tested.

Just as eclipses of the Sun and moon give astronomers rare opportunities to learn about those objects, an alignment in a nearby galaxy has provided a rare opportunity to investigate a supermassive black hole.

ESA's Darwin mission aims to discover extrasolar planets and examine their atmospheres for signs of life, particularly for the presence of certain life-related chemicals such as oxygen and carbon dioxide. The major technical challenge lies in distinguishing, or resolving, the light from an extrasolar planet from the hugely overwhelming radiation emitted by the planet's nearby star.

Cluster is providing new insights into the working of a ‘space tsunami’ that plays a role in disrupting the calm and beautiful aurora, or northern lights, creating patterns of auroral dances in the sky.

Stretching a carbon nanotube composite like taffy, researchers at the National Institute of Standards and Technology (NIST) and the Rochester Institute of Technology (RIT) have made some of the first measurements* of how single-walled carbon nanotubes (SWNTs) both scatter and absorb polarized light, a key optical and electronic property.
