Is there an "Air Supply" in the bat world?  Not really, though they seem to have love songs, say  researchers at Texas A&M University and the University of Texas at Austin

So let's look at the mysterious love sounds made by the winged creatures.

Women hedge and issue disclaimers and ask questions when they communicate, all traits that can suggest uncertainty and lack of confidence, but men do the same on gender-specific topics, according to new research from the University of California - Davis.

In his study, Nicholas Palomares, assistant professor of communication at UC Davis, asked nearly 300 UC Davis undergraduates, about half female and half male, to write e-mails explaining how to change a flat tire or buy make-up, among other gender-stereotyped and gender-neutral topics. Students were given the name and gender of the person they were e-mailing.

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.
