(Press-News.org) WASHINGTON, Nov. 12, 2024 – Indoor badminton courts are often used for high-stakes tournaments, but even an enclosed court can affect the path of a birdie.
The airflow from a court’s heating, ventilation, and air conditioning (HVAC) system and cross ventilation plays a significant role in badminton. The lightweight feathered birdie passed between the players can be affected by low wind speed in the stadium. This is known as wind drift and has been at the center of multiple tournament controversies. While shutting off the ventilation may seem like the solution, this can lead to player discomfort and negatively affect performance.
Research published in Physics of Fluids, published by AIP Publishing, proposed that different roof configurations could help mitigate wind drift. Author Karthik Jayanarasimhan recommends that important badminton games be played on courts with a barrel roof and a ventilation opening.
“This research can be recommended for the new upcoming badminton stadium construction, where the roof types and opening selection can be made based on our suggestions,” said Jayanarasimhan.
To determine the optimal roof shape for the least wind drift, the team modeled the airflow in a barrel roof stadium with different ventilation opening directions. They tested this against a simulation of a flat roof to understand the roof effects.
The authors acknowledge that it’s not possible to rebuild every badminton stadium based on the recommendations provided in this paper. Instead, their research emphasizes the importance of selecting the areas within the court with the lowest wind drift for playing badminton games.
“For an existing barrel roof stadium, renovating the opening will be a good solution. Reworking the roof will be much costlier,” Jayanarasimhan explained.
Jayanarasimhan hopes these findings will help the sports community realize that there are better solutions for mitigating wind drift beyond just turning off the ventilation.
“We expect that with this pace of research down the road, wind drift complaints will be negligible from badminton tournaments,” said Jayanarasimhan. “We are preparing to study other roof configurations [and] the deviation of the shuttlecock trajectory in different wind directions and conduct a case study of the existing indoor badminton stadiums.”

Ouch! Commonalties found in pain vocalizations and interjections across cultures
2024-11-12
WASHINGTON, Nov. 12, 2024 – There are an estimated 7,000 languages spoken worldwide, each offering unique ways to express human emotion. But do certain emotions show regularities in their vocal expression across languages?
In JASA, published on behalf of the Acoustical Society of America by AIP Publishing, an interdisciplinary team of linguists and bioacousticians led by Maïa Ponsonnet, Katarzyna Pisanski, and Christophe Coupé explored this by comparing expressive interjections (like “wow!”) ...
Income-related disparities in mortality among young adults with type 2 diabetes
2024-11-12
About The Study: In this cohort study of 1.2 million individuals ages 20 to 79 in South Korea, the risk of mortality with low income was most prominent among individuals with type 2 diabetes ages 20 to 39. These findings highlight the need for socioeconomic support to reduce income-related health disparities in younger individuals.

Medical board discipline of physicians for spreading medical misinformation
2024-11-12
About The Study: The frequency of discipline for physician-spread misinformation observed in this cross-sectional study was quite low despite increased salience and medical board warnings since the start of the COVID-19 pandemic about the dangers of physicians spreading falsehoods. These findings suggest a serious disconnect between regulatory guidance and enforcement and call into question the suitability of licensure regulation for combatting physician-spread misinformation.

First-ever randomized clinical trial uses telehealth for suicide prevention
2024-11-12
COLUMBUS, Ohio – Suicide remains a pressing public health concern. An estimated 703,000 people die by suicide each year worldwide, according to The World Health Organization. In 2022, there were 49,449 suicides in the United States.
A new study found that brief cognitive behavioral therapy for suicide prevention – when delivered remotely via video telehealth – reduces suicide attempts and suicidal ideation.
Researchers at The Ohio State University Wexner Medical Center and College of Medicine led the study that is published online in the journal JAMA Network Open.

DNA packaging directly affects how fast DNA is copied in cells
2024-11-12
Researchers from the Mattiroli group have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual pathway, affecting the cell’s ability to divide and grow. This opens up new doors to study how the copying of the DNA and its packaging are linked. These findings, published in Molecular Cell, may help scientists to find therapies and medicines for diseases such as cancer in the future.
Chromatin as a guide
Every day, our cells divide. Each time they need to copy both their DNA and the structure in which the DNA is packed. This packaging, ...
Scientists develop advanced catalyst for self-driven seawater splitting with enhanced chloride resistance

Early treatment for nerve tumors prevents serious problems, study finds
2024-11-12
Patients with a small cranial nerve tumor that can cause hearing loss, vertigo, imbalance and ringing in the ears have typically been watched rather than proactively treated, as the risks of early intervention were thought to outweigh the benefits. However, even those patients benefit significantly from non-invasive stereotactic radiosurgery, a multicenter, international study led by UVA Health physicians has found.
Doctors typically treat larger forms of the tumors, called vestibular schwannomas, while taking a “watch and wait” approach ...
