Everyone knows that placebo is capable of effectively reducing pain, but people respond differently to placebo treatment. A new study from the University of Luxembourg revealed that it depends heavily on person‘s ability to reinterpret negative events and to control feelings. Interestingly, this was figured out using fMRI technology. Placebo […]

For Myrna Caroline Jacques, digital storytelling is her way of fighting Alzheimer’s. “I thought maybe if I do this and use my brain, the disease won’t take over as soon. “That’s my goal,” the 77-year-old grandma of five said. She may be onto something. A recent UAlberta study on digital […]

A pair of English bulldog puppies are the first patients to be successfully treated with a unique therapy — a combination of surgery and stem cells — developed at the University of California, Davis, to help preserve lower-limb function in children with spina bifida. Because dogs with the birth defect […]

Drawing on available data on people with mild cognitive impairment (MCI) from the Alzheimer’s Disease Neuroimaging Initiative (ADNI), researchers at McGill University in Canada had trained a machine-learning algorithm to identify which patients will go on to develop dementia within a 24 month period with 84% accuracy. The data used […]

A mutation that helps make cells immortal is critical to the development of a tumor, but new research at UC Berkeley suggests that becoming immortal is a more complicated process than originally thought. The key to immortalization is an enzyme called telomerase, which keeps chromosomes healthy in cells that divide […]

Gastric carcinoma is one of the most common causes of cancer-related deaths, primarily because most patients present at an advanced stage of the disease. The main cause of this cancer is the bacterium Helicobacter pylori, which chronically infects around half of all humans. However, unlike tumour viruses, bacteria do not deposit […]

Scientists have identified a large group of biological ‘labels’ that guide nerves to ensure they make the correct connections and control different parts of the body. Although their research was conducted with fruit flies, the findings offer hope that we could one day reestablish nervous connections in people living with […]

A University of Queensland discovery may lead to new treatments for anxiety, depression and post-traumatic stress disorder (PTSD). UQ Queensland Brain Institute scientists have discovered that new brain cells are produced in the adult amygdala, a region of the brain important for processing emotional memories. Disrupted connections in the amygdala, […]

Our modern lives are extremely stressful. We have to rush pretty much everywhere and are always haunted by a huge fear of getting late and being replaced. However, you may want to consider this – a new study showed that stress may be a major contributor to the development of […]

UCLA researchers have discovered a new way to activate the stem cells in the hair follicle to make hair grow. The research, led by scientists Heather Christofk and William Lowry, may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss […]

Scientists studying how aging affects the biological clock’s control of metabolism have discovered that a low-calorie diet helps keep these energy-regulating processes humming and the body younger.
