A Tiny Hair-Like Filaments Takes Up New Shape In Inner Ear

Researchers examined a inner ear, ears are exquisite detection instruments, capable of discerning a whisper or distinct notes of music within a symphony. To pick up these sounds, tiny hair-like filaments in the inner ear must be packed into precisely arranged bundles, all facing the same direction. Images of the normal, tidy architecture of these bundles on cells within the cochlea, the inner ear structure responsible for hearing. The study was published in the Proceedings of the National Academy of Sciences.

Antioxidant Targets Old Blood Vessels And Convert To Them Young Again

Accoridng to a new stduy, researchers estimated that older adults who take a novel antioxidant that specifically targets cellular powerhouses, or mitochondria, see age-related vascular changes reverse by the equivalent of 15 to 20 years within six weeks. They adds to a growing body of evidence suggesting pharmaceutical-grade nutritional supplements, or nutraceuticals, could play an important role in preventing heart disease. The study was published in the American Heart Association journal Hypertension.

Music Is The Greatest Efficiency At reducing Arterial Pressure

Research shows anti-hypertensive drugs improve heart rate more in patients who listen to music after taking medication. Among musical genres, classical music is the one with greatest efficiency at reducing arterial pressure; authors of the study speculate whether music acts on the patients' parasympathetic system, increasing their capability of absorbing medication. The study was published in Scientific Reports.

Autistic Children May Inherit DNA Mutations From Their Parents

Over the past decade, researchers have firmly established that gene mutations appearing for the first time, called de novo mutations, contribute to approximately one-third of cases of autism spectrum disorder (ASD). Now, a new study, published in Science, probing so-called noncoding DNA has found that alterations in regions that regulate gene activity may also contribute to autism. And surprisingly, these variations tended to be inherited from fathers who aren’t autistic.
