John Hauptman stood before an international gathering of particle physicists and announced he had another idea.

One that was different. One that was simpler. And best of all, one that he was sure would work.

For the growing number of people with diminished immune systems - cancer patients, transplant recipients, those with HIV/AIDS - infection by a ubiquitous mold known as Aspergillus fumigatus can be a death sentence.

The fungus, which is found in the soil, on plant debris and indoor air, is easily managed by the healthy immune system. But as medical advances contribute to a growing population of people whose immune systems are weakened by disease or treatment, the opportunistic fungus poses a serious risk.

Last week I had the great good fortune to attend a three day energy conference attended by some of the world’s greatest energy experts.  Thanks to the good graces of the Foundation for the Future I was invited to attend the conference as an observer.  The Foundation invited 15 of the foremost physicists and energy experts in the world to come together for three days of presentations and discussions on the future of energy.  An additional 15 or so people were invited to attend as observers. 

Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. Speed is the key - the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat. How photosynthesis achieves this near instantaneous energy transfer is a long-standing mystery that may have finally been solved.

Researchers from Harvard Medical School and Beth Israel Deaconess Medical Center have captured and sequenced tiny pieces of collagen protein from a 68 million-year-old Tyrannosaurus rex. The protein fragments—seven in all—appear to most closely match amino acid sequences found in collagen of present day chickens.

Are birds and dinosaurs are evolutionarily related?

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.
