Cultivating a Music Studio to Sound Like an Indoor Forest #ASA183

At the 183rd ASA Meeting, researchers will describe “The evolution of Blackbird Studio C,” a space designed to provide an accurate and immersive mixing and production environment. They wanted to create a unique, ambient anechoic space that would allow ambient sound to decay equally across different frequencies and be free from interfering reflections, making it sound like an indoor forest. So they covered the walls and ceiling with primitive root diffusers. This technology causes sound energy to diffuse and radiate in many directions.

Warming climate spurs harmful oxygen loss in lakes

New research from Cornell University and Rensselaer Polytechnic Institute shows a continually warming world is leading to extended, late-summer weeks of water stratification in lakes, which prompts oxygen deprivation in the water – provoking conditions called hypoxia (low oxygen) and anoxia (no oxygen) – and negative consequences for fish and other species.

Itchy Eyes and a Runny Nose? It Could Be Climate Change

Researchers with the Rutgers Environmental and Occupational Health Sciences Institute have simulated how climate change will affect the distribution of two leading allergens – oak and ragweed pollens – across the contiguous United States. The results, published in the journal Frontiers in Allergy, may make your eyes water.

Parkinson’s medication improved blood pressure in teens with Type 1 diabetes

Teens with Type 1 diabetes (T1D) who took bromocriptine, a medication used to treat Parkinson’s disease and Type 2 diabetes, had lower blood pressure and less stiff arteries after one month of treatment compared to those who did not take the medicine, according to a small study published today in Hypertension, an American Heart Association journal.

Why Those Sounds From Your Upstairs Neighbor Are So Annoying #ASA183

At the 183rd ASA Meeting, Markus Mueller-Trapet will describe experiments designed to simulate and measure the perceived annoyance experienced from noisy neighbors in multi-unit residential buildings. He and his team provided a living room-like situation and recorded impact sounds of objects dropping and people walking. They then presented the recordings to study participants, using different playback techniques and virtual reality, and created an online survey. The team hopes to provide guidance to architects and building code developers.

Tiny Underwater Sand Dunes May Shed Light on Larger Terrestrial and Martian Formations

In Physics of Fluids, researchers have been studying the dynamics of how crescent-shaped sand dunes are formed. Known as barchans, these formations are commonly found in various sizes and circumstances, on Earth and on Mars. Using a computational fluid dynamics approach, the team carried out simulations by applying the equations of motion to each grain in a pile being deformed by a fluid flow, showing the ranges of values for the proper computation of barchan dunes down to the grain scale.

How Metastatic Cancer Causes Leaky Blood Vessels

In APL Bioengineering, researchers examine the local communication between endothelial cells and tumors cells and its effects on endothelial cell orientation. The approach uses co-cultured human umbilical vein endothelial cells and breast epithelial tumor cell lines to simulate the tumor-endothelial interaction. The group found the clockwise chirality of the hUVECs was less affected by local hormone signaling and more so by direct physical contact with tumor cells. Specific proteins on the tumor cell binding to others on endothelial cells appeared to play a role in changing the clockwise chirality of hUVECs.

Redesigning diabetes technology to detect low blood sugar in older adults with diabetes and Alzheimer’s disease

Regenstrief Institute Research Scientist April Savoy, PhD, a human factors engineer and health services researcher, is developing and testing user-friendly health information tools and technology designed to enhance accessibility and value to older adults with both diabetes and Alzheimer’s disease, and their caregivers.

Supersonic Travel, Without the Sonic Boom #ASA183

At the 183rd ASA Meeting, Gautam Shah will discuss plans to test a supersonic aircraft with technology to alter how supersonic shock waves behave and reduce sonic booms. NASA will conduct a series of flights over various communities across the U.S., and Shah and his team will measure the sound of the aircraft and conduct public surveys to understand the public response to different noise levels. By providing this information to regulatory agencies, the group hopes to inform an overland supersonic sound standard.

3D-Printed Violins Bring Music into More Hands #ASA183

Creating 3D-printed, low-cost, durable violins for music students, researchers have explored the factors that result in the best violin sounds and performed a concerto composed specifically for 3D-printed instruments. The violin was created in two sections. The body is made of a plastic polymer material and designed to produce a resonant tone, while the neck and fingerboard are printed in smooth ABS plastic to be comfortable in the musician’s hands. The result is a violin that produces a darker, more mellow sound than traditionally made instruments.

Hurricane’s effects killed sturgeon in Apalachicola River

As hurricane Michael churned through the Gulf of Mexico to make landfall near Florida’s Apalachicola River in 2018, it left a sea of destruction in its wake. The path was easy to follow on land, but debris and infrastructure failures also diminished the river’s water quality and led to the death of roughly half the gulf sturgeon population there.

Medical Students Lead Nationwide Movement to Excise Racism From Nephrology Curricula

As medical schools across the country grapple with the arduous process of revising their curricula to be anti-racist, students at the Icahn School of Medicine at Mount Sinai have turned a critical eye on the very textbooks that have trained medical students for years.

مدينة روتشستر، ولاية مينيسوتا. — يساعد البنك الحيوي الحي للثدي في مايو كلينك الباحثين في تحديد الطرق التي قد تزيد من احتمالية تعرض حاملي جينات معينة لخطر الإصابة بسرطان الثدي.

Immunotherapy eliminates disease-causing cells in mice with MS-like disease

Researchers at Washington University School of Medicine in St. Louis have shown that the cancer therapy known as CAR-T can be applied to multiple sclerosis (MS), an autoimmune disease of the nervous system. The findings extend the powerful tool of immunotherapy to autoimmune diseases, a class of diseases that are often debilitating and difficult to treat.

Listen to the Toilet — It Could Detect Disease #ASA183

Researchers describe how a noninvasive microphone sensor could identify bowel diseases without collecting any identifiable information. They tested the technique on audio data from online sources, transforming each audio sample of an excretion event into a spectrogram, which essentially captures the sound in an image. The images were fed to a machine learning algorithm that learned to classify each event based on its features. The algorithm’s performance was tested against data with and without background noises.

Machine Learning Diagnoses Pneumonia by Listening to Coughs #ASA183

Researchers have developed a machine learning algorithm to identify cough sounds and determine whether the subject is suffering from pneumonia. Because every room and recording device is different, they augmented their recordings with room impulse responses, which measure how the acoustics of a space react to different sound frequencies. By combining this data with the recorded cough sounds, the algorithm can work in any environment.

New blood test can detect ‘toxic’ protein years before Alzheimer’s symptoms emerge, study shows

Researchers can detect small “toxic” aggregates of a particular protein in the blood of individuals with Alzheimer’s disease and in individuals who showed no signs of cognitive impairment at the time the blood sample was taken, but who developed it at a later date.

Can a Playlist be Your Therapist? Balancing Emotions Through Music #ASA183

Researchers present an app that creates playlists to help listeners care for their emotions through music. The app could be used by people who may not want to receive counseling or treatment because of feelings of shame, inadequacy, or distrust and aims to leave them more positive and focused than they were when they began. Users take three self-led questionnaires to measure their emotional status and the app then creates a customized playlist of songs using one of three strategies: consoling, relaxing, or uplifting.

X-rays Reveal Elusive Chemistry for Better EV Batteries

A team of scientists led by chemists at the U.S. Department of Energy’s Brookhaven National Laboratory and Pacific Northwest National Laboratory has unraveled the complex chemical mechanisms of a battery component that is crucial for boosting energy density: the interphase.

Tailored approach makes inroads in rural firearm safe storage

A new study shows early promise for an approach that seeks to reduce the risk of firearm injury and death in rural areas, while respecting rural culture and firearm ownership. The effort tailors messages about safe firearm storage and teen firearm suicide to a rural audience, and shares specific tips for improving safety.

Shhhh … Speaking More Quietly in Restaurants Means Everyone Can Be Heard #ASA183

In a crowded restaurant, the sounds of conversations bounce off walls, creating background noise. Each individual wants to be heard, so they end up talking a little bit louder, which increases the overall din. Eventually – barring an interruption – the system gets loud enough to reach the limit of the human voice. Braxton Boren will discuss this cycle, called the Lombard effect, and how it can be disrupted in his presentation, “A game theory model of the Lombard effect in public spaces.”
