Controlled drug release using novel excipients: an interview with Dr Laura Waters, University of Huddersfield

When you take a medicine you may want the drug to all be released immediately or perhaps more slowly over a longer period of time. If we can make a medicine where we control the release then we can tailor our medicines to release at the exact rate we choose that is best for the patient.

Researchers hope voice therapy in aging humans may help improve quality of life

A new study shows that the vocal training of older rats reduces some of the voice problems related to their aging, such as the loss of vocal intensity that accompanies changes in the muscles of the larynx. This is an animal model of a vocal pathology that many humans face as they age.

Non-invasive odor analysis: A valuable technique for early diagnosis of melanoma

According to new research from the Monell Center and collaborating institutions, odors from human skin cells can be used to identify melanoma, the deadliest form of skin cancer. In addition to detecting a unique odor signature associated with melanoma cells, the researchers also demonstrated that a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells.
