UC Santa Barbara scientists have revealed what they call a potential new drug delivery system - a biological mechanism for delivery of nanoparticles into tissue.

They developed a peptide, a small piece of protein that can carry "cargo" for delivery into the cell, whose cargo could be a nanoparticle, or even a cell.

Riding on the peptide, the cargo gets out of the blood vessel and penetrates the tissue.

The so-called SHOX gene (short stature homeobox gene) is responsible for the normal growth of bones and is often mutated in short-stature patients. Short stature is considered when final height of an individual is no more than 160 cm (men) or 150 cm (women).

Researchers in Heidelberg have now discovered that sequences of genetic material on the X and Y chromosome that regulate this gene are also crucial for growth in children.

Is music more than the sum of its parts?   We're going to find out if the right words and musical notes can lead to Frankenstein-ish success.

The North Sea was once isolated from surrounding oceans and its change to a more fresh water state led to a significant reduction in the diversity of life, say a team of German and British scientists who have used fossilized shark teeth to reconstruct the climate of the North Sea during the Palaeogene period, between 40 and 60 million years ago. 

The Palaeogene was a time when greenhouse conditions prevailed and mammals began to diversify in the wake of the mass extinction event that saw the demise of the dinosaurs, along with 65% of all species.

Men, you aren't right a lot, as women will tell you, but here's one thing you got correct - women are complicated.

Even more complex than you think.   Women don't just have one standard for attractiveness, they have a few, and sometimes they even compete.   And it's equal to fertility and health on the 'women choose based on reproduction potential' mythology restated by the psychologists in the article.

If you have a Facebook page (we do) or any social media account, you may post varying amounts of personal information you want to share online with family, friends and colleagues - but a new study presented recently in Barcelona at the Workshop on Online Social Networks, part of the annual conference of the Association for Computing Machinery's Special Interest Group on Data Communications, has found that the practices of many popular social networking sites typically make that personal information available to companies that track Web users' browsing habits and allow them to link anonymous browsing habits to specific people.
