Gene Therapy Shows Potential To Reverse Alzheimer's Memory Loss

A world-first new treatment that reverses the effects of memory loss associated with Alzheimer’s disease has been discovered by Macquarie University researchers in a study of mice with advanced dementia. The research, co-led by two brothers, Dr. Arne Ittner and Professor Lars Ittner, from Macquarie University Dementia Research Center, builds on their work begun in 2016 involving a ground-breaking gene therapy which uses an enzyme that is naturally present in the brain, known as p38gamma.

Antioxidant-rich Foods Like Black Tea, Chocolate, And Berries May Increase Risk For Certain Cancers

One fact that has long baffled doctors is that cancer in the small intestine is quite rare, whereas colorectal cancer, taking place in the neighboring though much smaller organ, is one of the leading causes of cancer death for men and women. What is it about the colon that seems to attract cancer? To answer this question, Professor Yinon Ben-Neriah at Hebrew University of Jerusalem (HU)’s Lautenberg Center for Immunology and Cancer Research and his team led by Dr.

Bacteria In The Gut Have A Direct Line To The Brain

With its 100 million neurons, the gut has earned a reputation as the body’s “second brain” — corresponding with the real brain to manage things like intestinal muscle activity and enzyme secretions. A growing community of scientists are now seeking to understand how gut neurons interact with their brain counterparts, and how failures in this process may lead to disease. Now, new research shows that gut bacteria play a direct role in these neuronal communications, determining the pace of intestinal motility.

Brain Cartilage Changes May Explain Why Sleep Helps You Learn

The morphing structure of the brain’s “cartilage cells” may regulate how memories change while you snooze, according to new research. Sleep lets the body rest, but not the brain. During sleep, the brain accounts for a day of learning by making strong memories stronger and weak memories weaker, a process known as memory consolidation. But changing memories requires changing synapses, the connections between neurons. Sleep-induced changes need to overcome perineuronal nets, cartilage-like sheaths that not only surround and protect neurons, but also prevent changes in synapses.

Traumatic Brain Injury Damage May Come From Microbubbles

Microbubbles measured in microns — millionths of a meter — can form in cerebral spinal fluid inside the skull during traumatic brain injuries, according to new research. The “formation and dramatic collapse” of these microbubbles could be responsible for some of the damage in a brain injury, the researchers report. Bubble damage may sound trivial. But bubble collapse — a process known as cavitation — and the resulting shock waves can damage the steel foundations of boat propellers.

What Anxiety Does To Our Breathing

Stressful situations can cause anxiety, our body’s natural response to stress. But feelings of apprehension can also be accompanied by physical effects such as rapid breathing, increased heart rate and nausea. How our brain perceives these physical changes – in particular, breathing – could be key to better understanding anxiety disorders and treating them. Anxiety disorders are the most common mental health problem in Europe, affecting about 25 million people across the region.

Let’s Scrap The Neuromyths: No, You Aren’t A ‘Visual’ Or ‘Auditory’ Person

Who hasn’t heard the statement that we only use 10 per cent of our brain? That listening to Mozart’s music makes you smarter or that most learning happens in the first three years of life? Or that a person who is “right-brained” is more creative? Another widespread idea is that we are either visual, auditory or kinesthetic (more sensitive to touch) and that we learn better according to these “styles.”

Non-REM Sleep And REM Sleep Are Both Important For Visual Learning

Which sleep stage is most important for learning: REM or non-REM? Does sleep improve learning by enhancing skills while people snooze, or by cementing those skills in the brain so that they’re less likely to forget them? Do these processes occur every time someone sleeps, or only after they have learned something new? The answer to these questions, according to a new study on visual learning, is all of the above.
