X-rays show how periods of stress changed an ice age hyena to the bone
A few hundred thousand years ago during Earth's most recent ice age, a beefy subspecies of spotted hyena that was more than double the weight of its modern relative roamed Eurasia's snow-glazed terrain. Until their extinction about 11,000 years ago, these animals, now known as cave hyenas, would drag their prey into dens and devour them with bone-crushing jaws.

Resonant mechanism discovery could inspire ultra-thin acoustic absorbers
Resonant mechanism discovery could inspire ultra-thin acoustic absorbers
New research led by academics at the University of Bristol has discovered that the scales on moth wings vibrate and can absorb the sound frequencies used by bats for echolocation (biological sonar). The finding could help researchers develop bioinspired thin and lightweight resonant sound absorbers.

Oceanographers produce first-ever images of entire cod shoals
Oceanographers produce first-ever images of entire cod shoals
Wide-ranging acoustic images could help researchers identify populations on the brink of collapse. For the most part, the mature Atlantic cod is a solitary creature that spends most of its time far below the ocean's surface, grazing on bony fish, squid, crab, shrimp, and lobster - unless it's spawning season, when the fish flock to each other by the millions, forming enormous shoals that resemble frenzied, teeming islands in the sea.

Music improves social communication in autistic children
Improved communication skills may be linked to increased connectivity between auditory and motor regions of the brain, researchers at Université de Montreal and McGill University find Engaging in musical activities such as singing and playing instruments in one-on-one therapy can improve autistic children's social communication skills, improve their family's quality of life, as well as increased brain connectivity in key networks, according to researchers at Université de Montréal and McGill University.

Lift off for world-first ultrasound levitation that bends around barriers
Lift off for world-first ultrasound levitation that bends around barriers
Researchers at the University of Sussex have become the first in the world to develop technology which can bend sound waves around an obstacle and levitate an object above it. SoundBender, developed by Professor Sriram Subramanian, Dr Gianluca Memoli and Dr Diego Martinez Plasencia at the University of Sussex, is an interface capable of producing dynamic self-bending beams that enable both levitation of small objects and tactile feedback around an obstacle.

Researchers make big strides in noise cancellation
Researchers make big strides in noise cancellation
Researchers at The Australian National University (ANU) have found a way to cancel out the noise produced by things like motors and air conditioning units, providing some much-needed relief to anyone working or living in a noisy environment. Professor Thushara Abhayapala from the Research School of Engineering says it's a similar concept to the technology used in noise cancellation headphones - but on a much bigger scale.

Beatboxers' and guitarists' brains react differently to hearing music
Beatboxers’ and guitarists’ brains react differently to hearing music
The brains of professional beatboxers and guitarists respond to music differently when compared to each other and non-musicians, finds a new UCL-led study. The study, published in Cerebral Cortex and funded by Wellcome, sheds light on how learning and making music can affect mental processes. The researchers found that the area of the brain that controls mouth movements was particularly active when beatboxers listened to a previously unheard beatboxing track, while the 'hand area' of the guitarists' brains showed heightened activity when they listened to guitar playing.

Printing with sound
Highlights: > Harvard University researchers have developed a new printing technology that uses sound waves to control the size of liquid droplets independent of fluid viscosity > This approach could greatly broaden the types of liquids, including biopharmaceuticals, that can be printed drop-on-demand > The researchers used sound waves to generate a highly confined force at the tip of the printer nozzle, which pulls the droplet.

Making opaque materials totally transparent
Making opaque materials totally transparent
EPFL researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound waves can propagate at a constant amplitude - regardless of what may lie in their path. This method could eventually be used to make it possible to hide objects like submarines.

Sinfonia ai funghi
Sinfonia ai funghi
Do violins made of wood that had been treated with fungi sound the same as a fine, antique instrument? Acoustics experts at Empa are currently studying the body and soul of instruments made of "mycowood". Precision structure-borne sound measurements and psycho-acoustic tests with volunteers should reveal whether a fungal treatment can really improve an instrument.
