Ann Grand started her working life in the late 1970s as biology teacher. She retired after ten years but continued to be passionate about the excitement and exhilaration of science. Later, she took a degree with the Open University, studying topics from geology to systems theory. In 2003, she founded the Bristol Science Café and, in her spare time, sustains the work of the national and international network of science cafés, running the website and supporting and mentoring new café organizers. In January 2009, she started work on an interdisciplinary PhD research project, based at the University of the West of England, Bristol, seeking ways to bring Open Science and public engagement together in a fruitful and symbiotic way. The research project is funded by the Engineering and Physical Sciences Research Council (EPSRC).

Until now, medical opinion about the impact of vegetarian diets on bone health has been based on anecdotal evidence and a range of contradictory findings that sometimes rely on studies too small to be biologically relevant.

The salamander is a superhero of regeneration, able to replace lost limbs, damaged lungs, sliced spinal cord -- even bits of lopped-off brain. But it turns out that remarkable ability isn't so mysterious after all -- suggesting that researchers could learn how to replicate it in people.

Do friends wear the same style of shoe or see the same movies because they have similar tastes, which is why they became friends in the first place? Or once a friendship is established, do individuals influence each other to adopt like behaviors?

NASA's Lunar Reconnaissance Orbiter Camera (LROC) has taken and received its first images of the Moon, kicking off the year-long mapping mission of Earth's nearest celestial neighbor.

Women who get less than the recommended eight hours sleep a night are at higher risk of heart disease and heart-related problems than men with the same sleeping patterns.

Apologists for 'moderate' religion always start by saying that they accept science, and begin with arguments for god that seem to be superficially compatible with science, but ultimately end up saying they believe in absurdities that violate almost every major scientific principle, such as virgin births or that people can actually come back from the dead.

A molecule called telomerase, best known for enabling unlimited cell division of stem cells and cancer cells, has a surprising additional role in the expression of genes in an important stem cell regulatory pathway, say researchers at the Stanford University School of Medicine. The unexpected finding may lead to new anticancer therapies and a greater understanding of how adult and embryonic stem cells divide and specialize.

Researchers from across Europe have united to build the largest quantum key distribution network ever built. The efforts of 41 research and industrial organisations were realised as secure, quantum encrypted information was sent over an eight node, mesh network.

Scientists have performed the first DNA-based reconstruction of the giant extinct moa bird, using prehistoric feathers recovered from caves and rock shelters in New Zealand.
