Researchers have discovered a three-protein signature in the urine of patients with pancreatic cancer, bringing us closer to a much-needed noninvasive test for the disease. (Medical News Today)

Researchers solve mystery of how Akt "moves" from cytosol to cell membrane
Jialing Xiang, professor of biology at Illinois Institute of Technology, and her collaborators have solved a longtime mystery: how protein kinase (Akt), a key player in cell signaling, "moves" from... (Medical News Today)

Silk and stem cells may help engineer salivary glands for dry mouth
Use of silk fiber scaffolds may solve the problem of how to get salivary gland stem cells to grow into salivary gland tissue, opening the door to new treatments for dry mouth. (Medical News Today)

New structural features of human hair discovered
A new discovery about the structure of human hair is likely to change the way scientists and researchers, as well as the cosmetics industry, view and explore it in the future. (Medical News Today)

Stressed out plants send animal-like signals
University of Adelaide research has shown for the first time that, despite not having a nervous system, plants use signals normally associated with animals when they encounter stress. (Medical News Today)

'Leaky vaccines' could spur more dangerous disease
A new study shows how an imperfect vaccine may protect vaccinated individuals but allow the pathogen to evolve and put unvaccinated individuals at risk of more severe illness. (Medical News Today)

Anxiety, depression may be triggered by stress-induced changes to gut bacteria
Researchers suggest early-life stress may induce changes in gut bacteria that lead to the development of anxiety and depression later in life. (Medical News Today)
