Diminishing dinosaur steps saved by laser and laptop

.... Only one other department in the UK can boast such equipment. The equipment is generally used in oil exploration, but this project is the first time The University has used it to create images of dinosaur tracks.

Survival of the rarest: Fruit flies shed light on the evolution of behavior

...hese results may help explain why genetic variants such as these are common in nature. "In the case of fruit flies, one variant encourages the survival of the other. In essence, there is not one best type of fly," he says. If this process is common in nature, it may offer one explanation for why individua...

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

...an Retroviruses, could pave the way for the use of such peptides in gene therapy using HIV-based vectors as the delivery method. "Although it may seem counterintuitive to value or even study a peptide that increases the ability of HIV-1 to enter a broad range of human cells, retroviral vectors are curr...

In addition, minichromosomes could be used for the inexpensive production of multiple foreign proteins and metabolites useful for medical purposes. Because of their protein-ric...

Parasites' impact goes beyond host to affect ecosystem

...Cornell University, provided the ideal setting for such an experiment. While C. lingua infects approximately 10 percent of L. littorea living on the mainland, approximately half the snails on Appledore Island are infected. That’s because L. littorea is just one of three hosts in the life cycle of C. lingu...
