(Press-News.org) WASHINGTON, April 15, 2025 – With millions of dollars at stake across tournaments and more than 45 million regular annual participants, bowling continues to reign as a top sport in the U.S. A unified model that predicts how a bowling ball behaves down the lane, however, remains elusive.
In AIP Advances, by AIP Publishing, researchers from Princeton, MIT, the University of New Mexico, Loughborough University, and Swarthmore College share a model that identifies the optimal location for bowling ball placement. Employing a system of six differential equations derived from Euler’s equations for a rotating rigid body, their model creates a plot that shows the best conditions for a strike.
“The simulation model we created could become a useful tool for players, coaches, equipment companies and tournament designers,” said author Curtis Hooper. “The ability to accurately predict ball trajectories could lead to the discoveries of new strategies and equipment designs.”
To date, most methods for predicting the outcome of bowling shots have relied on statistics describing real-life bowlers, rather than analyzing the dynamics of the ball and shot itself. Such approaches have often come short when players introduce slight variability in how they bowl.
Instead, the group’s model accounts for a variety factors. One example is the thin layer of oil applied to bowling lanes; the oil layer can vary widely in volume and shape between competitive tournaments, requiring specific styles and targeting strategies for each. The oil is seldom applied uniformly, which creates an uneven friction surface.
The issue is that bowlers and coaches can currently only rely on their own experience and instinct, which Hooper said is often imprecise and suboptimal.
“Our model provides a solution to both of these problems by constructing a bowling model that accurately computes bowling trajectories when given inputs for all significant factors that may affect ball motion,” Hooper said. “A ‘miss-room’ is also calculated to account for human inaccuracies which allows bowlers to find their own optimal targeting strategy.”
Making the model posed several challenges, including how to describe the motion of the subtly asymmetric bowling ball. More challenging still was distilling the inputs required for predicting the trajectory into terms that a bowler or coach could understand and that could be measured with accessories bowlers already use.
In the future, the group aims to improve the model’s accuracy by incorporating even more factors, including uneven bowling lanes, as well as connect with professionals in the industry to better understand how the model may be tailored to fit their applications.

WASHINGTON, April 15, 2025 – Surround-sound speakers can immerse you in a multimedia experience, but what if there was a speaker that could completely re-create a three-dimensional soundscape?
The AudioDome is more than just a loudspeaker arrangement — it’s a dome of speakers that can create an immersive sound experience that reproduces sound sources at any location when the listener is placed in the middle.

Screening history, stage at diagnosis, and mortality in screen-detected breast cancer
2025-04-15
About The Study: In this cohort study of older women with screen-detected estrogen receptor–positive or human epidermal growth factor receptor 2–negative breast cancer, prior screening mammography was associated with earlier stage at breast cancer diagnosis and lower breast cancer mortality. These findings support the potential for routine screening to improve breast cancer outcomes. As with all observational studies, this study is limited by the potential effects of other differences between the screening and nonscreening groups.

Pitt researchers release Phage images with unprecedented detail
2025-04-15
Researchers at Pitt have produced the most detailed image to date of a bacteriophage–phage for short–that has allowed them to see for the first time the structural makeup of the part of the phage that directly attaches to its target Mycobacterium cell.
“Now you've got like a spec sheet for going in and designing phages so that they’ll bind to different kinds of cells,” said Graham Hatfull, the Eberly Family Professor of Biotechnology in the Kenneth P. Dietrich School of Arts and Sciences.
That’s important because of what a phage, which is a kind of virus, does after it binds to a bacterial cell: it pierces a hole in the cell membrane and injects ...

University of Virginia researcher Natasha D. Sheybani, PhD, has received $5.5 million from the federal Department of Defense to support her cutting-edge efforts to use focused sound waves to improve our immune system’s ability to battle breast cancer.
Sheybani, the research director of UVA’s Focused Ultrasound Cancer Immunotherapy Center, was the only scientist in the nation selected to receive a Breast Cancer Research Program Era of Hope Scholar Award in the latest funding round; she is UVA’s first recipient of the award. She will use the grant to advance her research into the potential of focused ultrasound to improve the safety, ...

Study identifies U.S. hotspots for drinking water quality violations and lack of access to safe, clean water
2025-04-15
Herndon, VA, March 25, 2025 -- About two million people in the United States lack access to running water or indoor plumbing in their homes. Another 30 million people live where drinking water systems violate safety rules. Water privatization -- the transfer of public water systems ownership and/or management to private companies -- has been proposed as a potential solution to provide more Americans with safe, clean drinking water. But opponents argue that private companies may prioritize profits over public needs.

Busted! Researchers revolutionize fraud detection with machine learning
2025-04-15
Fraud is widespread in the United States and increasingly driven by technology. For example, 93% of credit card fraud now involves remote account access, not physical theft. In 2023, fraud losses surpassed $10 billion for the first time. The financial toll is staggering: credit card fraud costs $5 billion annually, affecting 60% of U.S. cardholders, while identity theft resulted in $16.4 billion in losses in 2021. Medicare fraud costs $60 billion each year, and government losses range from $233 billion to $521 billion annually, with improper payments totaling $2.7 trillion since 2003.

Coastal heritage threatened by climate change
2025-04-15
Humans have always lived by coasts and waterways, and thus these locations are rich with archeological sites. Natural and cultural resource management are conducted separately, despite the fact that climate change, sea level rise, and extreme weather threaten them both. Jayur Mehta and colleagues argue a synergy of both approaches is required to protect coastal archaeological landscapes. The authors used LiDAR digital elevation models, site location data, and NOAA sea level rise models to define ...
