New research is hoping to understand how the human brain hears sound to help develop improved hearing aids and automatic speech recognition systems.

Cell’s ‘battery’ found to play central role in neurodegenerative disease
A devastating neurodegenerative disease that first appears in toddlers just as they are beginning to walk has been traced to defects in mitochondria, the ‘batteries’ or energy-producing power plants of cells.
Your appetite might be linked to risk of Alzheimer’s disease

Alzheimer’s disease – Appetite might be linked to risk of Alzheimer’s
The hormone leptin controls your appetite
Leptin is a potent and important appetite-regulating hormone – if you’ve just polished off a couple plates of food at a buffet, your blood leptin levels will rise and signal to your brain that you’re full.
The picture to the right shows an obese mouse that is missing the leptin gene and thus doesn’t produce leptin in its body. When it starts eating, it doesn’t stop and becomes obese.
The same thing happens in a small population of humans who are missing the leptin gene. They can’t control their appetite and get fat. But as always in biology, the story is more complicated. Some obese people have exactly the opposite effect – higher leptin levels than normal.
This might be because they have a genetic defect that makes them resistant to the effects of the hormone – when their bodies detect that the existing leptin in the bloodstream isn’t working, more leptin is pumped out, leading to higher levels.
Higher leptin = less risk of Alzheimer’s disease
A group of researchers based in Boston University have just finished an epic 12-year study of over 750 elderly people, where they tracked leptin levels and brain function (with brain scans). In short, they found that people with overall higher leptin levels at the start of the study ended up with less Alzheimer’s disease and healthier brains.
This is exciting because it would be extremely powerful to find a way to predict whether somebody is going to get Alzheimer’s disease later in their life, allowing early intervention and treatment – this study shows that leptin might be a useful predictive biomarker.
Now you might be thinking, if people with lower leptin levels get more Alzheimer’s disease, why don’t we give them some more leptin? Great minds think alike, because that’s exactly what Dr. J. Wesson Ashford and the Stanford/VA Alzheimer’s Center received $3M from the NIH (National Institute of Health) to look into.
Of course, any clinical application of this leptin / Alzheimer’s disease work is still many years away, but it’s good to see progress being made in understanding risk factors for Alzheimer’s disease.
How To Maximize The Potential Of Your Memory
Having a great memory can help you succeed in life, in school, and in your job. Memory can help you be more profitable, gain more knowledge and improve your interpersonal relationships. Your memory can be easily sharpened by practicing memory techniques, and making some lifestyle changes.

Find ways to incorporate fish oil into your regular diet. If you find your memory is not what it used to be, you may not be getting enough Omega-3 fatty acids in your diet. You can choose to take it as a daily dietary supplement.
Get up and walk away from your study or work routine for a minimum of five minutes per hour. Your brain requires a rest and relaxation period to better handle what you have provided. This makes it easier for you to retain important matters more effectively.
Get adequate rest. Make sure you’re getting good sleep, too--eight hours a night isn’t enough if you’re waking every few minutes or sleep on an uncomfortable bed. In fact, sleep plays a vital role in both your short-term and long-term memory. When brain cells are weary, they will not help you with memory retention. Get enough restful sleep during the night to aid your memory.
Ever experienced the feeling of something on the tip of your tongue? If you find yourself doing this often, you are not alone. Just take a step back and breathe deeply, and thing about the word and how you can remember it. Your mind can remember, it just takes patience. When you do this, you can just let the word you’re trying to think of come to mind.
There is a ton of information you should learn and keep in mind, and it will help you study at a lot of different places. If you’re stuck in the same location learning material, then you will associate material with only specific location.
