Imagine a world where damaged organs in your body—kidneys, liver, heart—can be stimulated to heal themselves. Envision people tragically paralyzed whose injured spinal cords can be repaired. Think about individuals suffering from the debilitating effects of Parkinson’s or Alzheimer’s relieved of their symptoms – completely and permanently.

Want to keep kids thin? Clore Laboratory at the University of Buckingham is supplementing infant formula and other baby foods with leptin,the hunger hormone. Researchers say it could provide permanent protection from obesity and diabetes into adulthood and could be on shop shelves soon.

Those who take the foods early in life should remain permanently slim. 'Like those people who are lean by nature even though they overeat ? like we all do – they will tend to be inefficient in terms of using energy,' says Mike Cawthorne, who heads the Metabolic Research group at Clore.

EU legislation to promote the uptake of biodiesel will not make any difference to global warming, and could potentially result in greater emissions of greenhouse gases than from conventional petroleum derived diesel. This is the conclusion of a new study reported today in Chemistry & Industry.

Analysts at SRI Consulting compared the emissions of greenhouse gases by the two fuels across their overall life cycles from production to combustion in cars.

A spectacular fossilised forest has transformed our understanding of the ecology of the Earth’s first rainforests. It is 300 million years old.

The forest is composed of a bizarre mixture of extinct plants: abundant club mosses, more than 40 metres high, towering over a sub-canopy of tree ferns, intermixed with shrubs and tree-sized horsetails. Nowhere elsewhere on the planet is it possible to (literally) walk through such an extensive swathe of Carboniferous rainforest.

Medical professionals conducting clinical trials should provide more information about financial conflicts of interest before they talk to patients about participating in the trials.

That is one of the main conclusions of a new survey by researchers from Duke University Medical Center and Johns Hopkins University. Their study found that 41 percent of the clinical trial coordinators surveyed had experience disclosing financial aspects of the trial to potential participants, and 28 percent of the coordinators had been asked by participants about potential financial conflicts.

New research from Columbia's Primate Cognition Laboratory has demonstrated for the first time that monkeys could acquire meta-cognitive skills: the ability to reflect about their thoughts and to assess their performance.

The study was a collaborative effort between Herbert Terrace, Columbia professor of psychology & psychiatry, and director of its Primate Cognition Laboratory, and two graduate students, Lisa Son — now professor of psychology at Barnard College — and UCLA postdoctoral researcher Nate Kornell.
