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. In a study appearing today in the journal Cell, Paolo Sassone-Corsi, director of the Center for Epigenetics & Metabolism at the University of […]

An international team of scientists, led by University of California San Diego School of Medicine researchers, has created a human stem cell-based model of a rare, but devastating, inherited neurological autoimmune condition called Aicardi-Goutieres Syndrome (AGS). In doing so, the team was able to identify unusual and surprising underlying genetic […]

The first few weeks after sperm meets egg still hold many mysteries. Among them: what causes the process to fail, leading to many cases of infertility. Despite the importance of this critical stage, scientists haven't had a good way to explore what can go wrong, or even what must go […]

Like much of the rest of the body, the brain loses flexibility with age, impacting the ability to learn, remember and adapt. Now, scientists at University of Utah Health report they can rejuvenate the plasticity of the mouse brain, specifically in the visual cortex, increasing its ability to change in […]

In the brains of Alzheimer’s patients, many of the genes required to form new memories are shut down by a genetic blockade, contributing to the cognitive decline seen in those patients. MIT researchers have now shown that they can reverse that memory loss in mice by interfering with the enzyme […]
