Experimental device could help ease tinnitus symptoms by targeting unruly nerve activity in the brain

Millions of Americans hear ringing in their ears -- a condition called tinnitus -- but a new study shows an experimental device could help quiet the phantom sounds by targeting unruly nerve activity in the brain.

Study finds new brainstem changes in Parkinson’s disease

A pioneering study has found that patients with Parkinson's disease have more errors in the mitochondrial DNA within the brainstem, leading to increased cell death in that area.

Scientists discover mechanism that amplifies autoimmune reaction in early stage islet autoimmunity

Scientists at Helmholtz Zentrum München have discovered a mechanism that amplifies the autoimmune reaction in an early stage of pancreatic islet autoimmunity prior to the progression to clinical type 1 diabetes.

Regular skiing and running at low altitudes can delay aging

Most biologists and medical professionals would agree that skiing and running can delay aging. This is essentially because of the direct positive impact on the body due to good exercise and physical fitness.

Multifunctional protein also plays role in development of blood cells

Like an actor who excels at both comedy and drama, proteins also can play multiple roles. Uncovering these varied talents can teach researchers more about the inner workings of cells.

Stem cells remain healthy following low-dose X-ray exposure, say biophysicists

Biophysicists have shown that following low-dose exposure to X-rays (at 80 milligrays), stem cells remain healthy, proliferate, and do not accumulate DNA damage to be passed on to their progeny. The paper was published in the journal Aging.

Excessive copper in diabetes impedes ability to make new blood vessels

It's a metal we worry thieves will steal from our air conditioners or power lines, but inside our bodies too much copper can result in a much larger loss.

Researchers suggest role for MKL1 protein in development of inflammatory bowel disease

Inflammatory bowel disease (IBD), including the two conditions ulcerative colitis and Crohn's disease, results in long-term inflammation of the gut and is associated with dysregulation of the immune system.

Bipolar disorder may involve accelerated epigenetic aging, study finds

Bipolar disorder may involve accelerated epigenetic aging, which could explain why persons with the disorder are more likely to have - and die from - age-related diseases, according to researchers from The University of Texas Health Science Center at Houston.

Optogenetics research sheds new light on social-spatial learning

Ilana Witten didn't set out to study spatial learning. She thought she was investigating how mice socialize--but she discovered that in mouse brains, the social and the spatial are inextricably linked.

Specific protein negatively affects pancreatic cells and leads to cancer growth

Pancreatic cancer is one of the most aggressive forms of cancer and is currently very difficult to treat. However, the last few years have seen advances in the scientific understanding of how this cancer develops at a molecular level.

Deep brain stimulation at low frequencies improves cognitive performance of PD patients

A multidisciplinary neuroscience study using rare, intraoperative brain recordings suggests that low frequency stimulation of a deep brain region may be able to improve cognitive function in patients with Parkinson's disease.

Researchers reveal impact of RNA-binding protein on memory formation process

Learning requires the chemical adaptation of individual synapses. Researchers have now revealed the impact of an RNA-binding protein that is intimately involved in this process on learning and memory formation and learning processes.

Treatment with endogenous protein can heal scarring in the lungs

The endogenous protein RAGE, which has usually been negatively associated with chronic inflammation and diabetic complications, plays a major role in the repair of DNA damage - and also appears to heal tissue damaged as a result of accelerated cell senescence.

Researchers explore new method of destroying tumor cells

Researchers from Lomonosov MSU Faculty of Biology have studied the stages of entosis, a process of cell death when one cell invades the other and gets digested inside of it. Entosis could become a new method of destroying cancer cells.
