Can Magnetism Bend Heat And Sound? Study Reveals A New Dimension to Magnetic Fields

Source: The Science Times

Heat and sound waves can be manipulated with magnetic fields, according to a study by Ohio State University scientists. They were able to control acoustic phonons, a cousin to photons, with a magnetic field as big as an MRI machine. "This adds a new dimension to our understanding of acoustic waves. We've shown that we can steer heat magnetically. With strong enough magnetic fields, we should be able to steer sound waves, too," said Joseph Heremans, who led the study published in Nature Materials.

Swiss Scientists Bioprint Cartilage

Scientists at ETH Zurich have developed a technique that would use patients' own cartilage to 3D-print nose and ear implants, which could require less surgery than current methods of creating cartilage implants. The bioprinting technique mixes cartilage cells with biopolymers to create the implant; the biopolymers will eventually break down and only cartilage will be left. Animal trials will occur later this year.

Cochlear Implantation Improved Speech Perception, Cognitive Function in Older Adults

Cochlear implantation was associated with improved speech perception and cognitive function in adults 65 years or older with profound hearing loss, according to a report. Hearing impairment is associated with cognitive decline, the researcher say.

Voices in People’s Heads More Complex than Previously Thought

Voices in people's heads are far more varied and complex than previously thought. One of the largest and most detailed studies to date on the experience of auditory hallucinations, commonly referred to as voice hearing, found that the majority of voice-hearers hear multiple voices with distinct character-like qualities, with many also experiencing physical effects on their bodies. The study also confirmed that both people with and without psychiatric diagnoses hear voices.

Adult Musicians with Hearing Loss Find Opportunities through AAMHL

Adult musicians with hearing loss may be interested in some of the opportunities provided by the Association of Adult Musicians with Hearing Loss (AAMHL). A nonprofit organization based in Rockville, MD, the Association was founded as a resource for musicians with hearing loss to discuss the challenges they face in making and listening to music.

Myelin-Maker: How an FDA-Approved Drug Boosts Myelin Synthesis

A researcher has discovered a way to keep remyelination going, using a drug that's already on the market. Damage to myelin, the fatty insulator that enables communication between nerve cells, characterizes multiple sclerosis (MS) and other devastating neurological diseases.

Unusual Disease that Causes Acute Confusion May Be Underdiagnosed

An unusual disease called Susac syndrome, which can cause acute confusion and problems with hearing and eyesight, is rare but probably under reported, physicians report.

Detecting Cancer By Sound [Audio]

The ear is quicker than the eye. People can detect changes in sound in a few thousandths of a second while their eyes need about a fiftieth of second to spot a change. This audio ability has prompted researchers to take information normally shown visually and turn it into sounds, a process called sonification. It allows researchers to pick up on differences at faster rates.

Mystery of your Fridge’s Strange Noises Solved

Source: Daily Mail

Anyone who has walked into their kitchen at night will have heard it - a series of strange pops and cracks emanating from the refrigerator. The source of these loud knocks and groans has baffled manufacturers, who have sought fruitlessly to solve the problem. But now scientists claim to have identified the source of the mysterious noises. Using specialised sensors they found that the noises occur due to the contraction and expansion of the fridge components and panels as they change temperature.
