Mccarthy AM, Wills JA, Fain AC, Nindl BC, Beach AJ +1 more

Plain English
This study looked at how well a new system called HumanTrak can measure shoulder movement angles when soldiers wear body armor. They tested 17 people doing specific shoulder movements, comparing HumanTrak to traditional methods, and found that HumanTrak worked well for movements like shoulder flexion, extension, and abduction, with accuracy scores between 56% and 93%. However, it did not accurately measure shoulder adduction, which is more complex, showing less reliability.

Sports biomechanics

Doyle EW, Doyle TLA, Bonacci J, Beach AJ, Fuller JT

Plain English
This study looked at how running speed affects the forces and stress on the kneecap in recreational runners. Researchers found that while running faster (at speeds of 3.1-4.2 meters per second) increases the immediate force on the kneecap by about 9% to 36%, it actually reduces the overall stress accumulated over a distance of 1 kilometer by 9% to 34% compared to slower speeds. This is important because it suggests that running at moderate speeds may help prevent knee pain more effectively than running slowly. Who this helps: This benefits recreational runners who want to avoid knee pain.

Homology Requirements and Competition between Gene Conversion and Break-Induced Replication during Double-Strand Break Repair.

2017

Molecular cell

Mehta A, Beach A, Haber JE

Plain English
This study looked at how yeast cells repair their DNA when it gets damaged. The researchers found that when one end of the DNA break has a similar stretch of DNA (up to 150 base pairs), repair favors gene conversion, a process that uses a similar sequence as a template. However, if the second end has less similarity, the cells switch to a different repair method called break-induced replication. Interestingly, they discovered that blocking certain genes can significantly increase the repair efficiency by gene conversion, suggesting that the process is flexible and can change based on the conditions. Who this helps: This research benefits scientists and researchers studying DNA repair mechanisms, which could enhance understanding in both health and disease contexts.

Testing the efficacy of a brief sexual risk reduction intervention among high-risk American Indian adults: study protocol for a randomized controlled trial.

2016

BMC public health

Chambers R, Tingey L, Beach A, Barlow A, Rompalo A

Plain English
This study examined a program designed to help American Indian adults reduce risky sexual behaviors and substance use. Researchers tested an intervention focusing on increasing condom use and found that it significantly helped participants, especially those dealing with mental health and substance use issues. If successful, this program could lead to better sexual health and reduced rates of infections like chlamydia and gonorrhea in this community. Who this helps: This benefits American Indian adults at risk for sexually transmitted infections and substance use problems.

Introducing the Postsecondary Instructional Practices Survey (PIPS): A Concise, Interdisciplinary, and Easy-to-Score Survey.

2016

CBE life sciences education

Walter EM, Henderson CR, Beach AL, Williams CT

Plain English
This study introduced a new survey called the Postsecondary Instructional Practices Survey (PIPS) to evaluate how college instructors teach across various subjects. The survey includes 24 statements about teaching methods and was tested with nearly 900 responses from different departments, showing it effectively captures both instructor-centered and student-centered teaching practices. Understanding these teaching methods is important because it helps improve the quality of education and informs policy decisions in higher education. Who this helps: This helps educators and administrators in colleges and universities.

Mechanisms by which different functional states of mitochondria define yeast longevity.

2015

International journal of molecular sciences

Beach A, Leonov A, Arlia-Ciommo A, Svistkova V, Lutchman V +1 more

Plain English
This study looked at how different conditions of mitochondria, the energy-producing parts of cells, affect the lifespan of yeast. Researchers found that as yeast age, their mitochondria don’t work as well, which is a key factor in how cells and organisms age overall. Understanding these processes can help scientists identify ways to improve health and longevity in various organisms. Who this helps: This helps researchers studying aging and potential therapies for age-related diseases.

Lithocholic bile acid accumulated in yeast mitochondria orchestrates a development of an anti-aging cellular pattern by causing age-related changes in cellular proteome.

Cell cycle (Georgetown, Tex.)

Beach A, Richard VR, Bourque S, Boukh-Viner T, Kyryakov P +7 more

Plain English
This study looked at how lithocholic bile acid (LCA) affects yeast cells, specifically how it changes the proteins in their mitochondria, the energy-producing parts of the cells. Researchers found that LCA helps extend the lifespan of yeast by influencing the levels of many mitochondrial and other proteins, leading to three distinct patterns that respond to aging. This matters because it reveals new ways to potentially promote longevity by understanding how cellular changes can be triggered at different stages of life. Who this helps: This helps researchers and scientists studying aging and potential anti-aging therapies.

Exosomes: an overview of biogenesis, composition and role in ovarian cancer.

2014

Journal of ovarian research

Beach A, Zhang HG, Ratajczak MZ, Kakar SS

Plain English
This study looked at exosomes, which are tiny particles released by cells, to understand their role in ovarian cancer. Researchers found that exosomes from ovarian cancer patients contain unique proteins and RNA that are different from those found in healthy individuals. This difference could help create a new diagnostic tool for detecting ovarian cancer early, which is important because early detection can lead to better treatment outcomes. Who this helps: This helps patients by providing a potential early detection method for ovarian cancer.

Mechanism of liponecrosis, a distinct mode of programmed cell death.

2014

Cell cycle (Georgetown, Tex.)

Richard VR, Beach A, Piano A, Leonov A, Feldman R +13 more

Plain English
This study looked at how a specific type of cell death, called liponecrosis, happens in yeast when exposed to a fatty acid known as palmitoleic acid (POA). The researchers found that when yeast cells take in POA, it causes a buildup of certain lipids in their membranes, leading to increased cell permeability and damage that ultimately leads to cell death. They discovered that if the cells activate certain protective mechanisms, such as breaking down dysfunctional mitochondria or incorporating POA into harmless lipids, they can avoid this cell death process. Who this helps: This research could help scientists understand cell death processes that may be relevant to diseases in humans, potentially guiding treatment approaches.
