Building a dinosaur from a chicken: Jack Horner on TED

Paleontologist Jack Horner has spent his career trying to reconstruct a dinosaur. He's found fossils with extraordinarily well-preserved blood vessels and soft tissues, but never intact DNA. So, in a new approach, he's taking living descendants of the dinosaur (chickens) and genetically engineering them to reactivate ancestral traits — including teeth, tails, and even hands — to make a "Chickenosaurus".

Stem cells: between science and ethics

The Italian Constitution guarantees scientific freedom. Based on this affirmation, seemingly simple and obvious, the Document issued by the Commission on ethical problems, posed by the science of the Waldensian Church, reiterates what should be considered a fundamental point in the debate, today more fervent than ever, regarding scientific research on human embryonic stem cells.

Edith Widder: The weird, wonderful world of bioluminescence

In the deep, dark ocean, many sea creatures make their own light for hunting, mating and self-defense. Bioluminescence expert Edith Widder was one of the first to film this glimmering world. At TED2011, she brings some of her glowing friends onstage, and shows more astonishing footage of glowing undersea life.

Submitted by Luca Carra on 24 May, 2011 - 15:13

How climate change will affect public health, socioeconomic and ecological trends in the Mediterranean Region? Researchers from all over Europe, North Africa and Middle East are gathering in Rome and discussing these issues in the Final Conference (23-25 May 2011) of CIRCE (Climate Change and Impact Research: the Mediterranean Environment), the research project funded under the Sixth Framework Programme of European Union (EU). The aim of the meeting is  to summarise 4-years project major outcomes  and achievements on the effects of climate change in the Mediterranean Basin.

Will anticoagulants be the new blockbuster?

di Pier Mannuccio Mannucci
Pubblicato il 13/05/2011
Medicine

In 2010, the European Medicines Agency (EMA) has approved the lowest number of new drugs in the last decade. This is not surprising, considering that it takes at least 10 years to register a drug, the total cost is about one billion dollars, and that at least 9 out of 10 of those for which clinical development is initiated, fall by the wayside. Some striking example? Rimonabant for obesity and metabolic syndrome, the monoclonal antibody ocrelizumab for rheumatoid arthritis and systemic lupus erythematosus.

Copper kills bacteria: end of hospital-acquired infections?

Prof. Hans Bärlocher left the hospital after a long working day. Outside the building, he took a deep breath of fresh Spring air; then, he smelled his right hand. Yes, it had the faint, but typical copper smell. This reassured him that he had not pick up any germs when going through the series of doors to leave the clinic. All the doors in his hospital had recently been refitted with door handles and push plates of antimicrobial copper. Also, many other items of stainless steel, like trays, bed rails, bathroom fixtures or toilet seats had been replaced by corresponding

Year of chemistry: some reflections

Science history

Chemical and physical sciences have profoundly modified the living conditions of mankind, in particular chemistry has played a central role. Its creative power has made available a range of new materials and processes for the transformation of matter. Somehow, however, these have often been perceived as unnatural and opposed to the natural ones. As a result the question of a control by society has become more and more actual. This requires that information be available to the public and to decision-makers for
