(Press-News.org) New research published in International Studies of Economics sheds light on an important but often overlooked driver of racial segregation in housing: minimum lot size zoning policies, or local regulations requiring a minimum amount of land for a property.
The study focused on the impact of minimum lot size regulations in Connecticut towns on the likelihood of ethnic minorities integrating into a community. Investigators found that households with higher incomes are more willing to pay for larger residential lots, reinforcing economic divides, and that Black households (after controlling for income) show a significantly lower willingness to pay for larger lots compared with white households, highlighting a racial preference effect.
The results indicate that minimum lot size regulations can cause racial segregation not only through income effects but also through voluntary choices by different racial groups.
“Together, these dynamics mean that minimum lot size regulations don’t just shape neighborhoods—they entrench segregation. By quantifying this impact at the household level, the research provides robust, data-driven evidence that these common land use policies have far-reaching social consequences,” said corresponding author Ling Huang, PhD, of the University of Connecticut. “This work is vital for policymakers, urban planners, and housing advocates. It offers a compelling case for reforming zoning laws to promote more equitable and inclusive communities.” Specifically, relaxing minimum lot size regulations and allowing smaller lots could help communities to reduce the extent of racial segregation from housing policies.

New method noninvasively measures Achilles tendon structure and function in professional dancers
2025-10-22
A study in the Journal of Orthopaedic Research uses a noninvasive, nonradioactive imaging-based method to measure the structure and function of the Achilles tendon in professional ballet dancers. The method could potentially be developed to help prevent injuries and improve rehabilitation efforts in athletes, as well as in the general public.
The study involved what is called multi-echo ultrashort echo time (UTE) magnetic resonance imaging (MRI) to assess collagen and other components of the Achilles tendon. These ...
Does floral scent affect insect visitors and bacterial strains on flowers?
2025-10-22
Using information on alpine plant species, researchers investigated how the chemistry of flowers’ scent affects not only the diversity of insect pollinators but also the communities of bacteria living on the flowers.
The study, which is published in New Phytologist, reveals that high floral scent chemodiversity—or the presence of a range of different chemical compounds—is associated with increased pollinator richness but reduced bacterial richness on flowers. The findings led the scientists ...
How is radiation therapy portrayed in art?
2025-10-22
Because patient perceptions of radiation can influence their willingness to receive it as treatment, researchers recently examined how radiation therapy is represented in different forms of art.
The analysis in the Journal of Medical Radiation Sciences found that overall, novels, poems, music, film, and paintings tend to depict radiation therapy as associated with fear, mystery, and fascination.
The authors note that radiation therapy is widely perceived as having both lifesaving and life-threatening potential. As such, exploring how radiation therapy ...
Emotional strain of fitness and calorie counting apps revealed
2025-10-22
Some users of popular fitness and calorie counting apps experience shame, disappointment and demotivation, potentially undermining their health and wellbeing, according to a new study led by researchers at UCL (University College London) and Loughborough University.
The study, published in the British Journal of Health Psychology, looked at 58,881 posts on Twitter (i.e., posted prior to the platform becoming X) relating to five popular fitness apps*.
The research team used AI models to filter out 13,799 posts judged to contain negative sentiment and then to group these posts into broad themes or topics.
They found users expressing ...
Uncovering the biology of growing old
2025-10-22
Scientists have long sought measurable signs in the body, called biomarkers, that reliably reveal our biological age or predict future health issues. Now, a new study in dogs—an ideal model for this research because they share our genetic diversity, diseases, and home environments—has uncovered molecular clues that could shed light on how aging unfolds in pets and people alike.
For the study published October 22 in Aging Cell, scientists from the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University, University of Washington, and other institutions analyzed blood samples from a group of nearly 800 dogs enrolled ...
Why do so many pro soccer players develop osteoarthritis?
2025-10-22
A new paper in Rheumatology, published by Oxford University Press, finds that retired UK male professional football players who reported foot or ankle injuries during their careers were more likely to develop osteoarthritis in retirement. Retired players treated routinely with cortisone injections for their injuries were even more likely to report osteoarthritis.
Professional football is a high-speed contact sport with high risk of injury. Foot and ankle injuries are particularly common, with ankle sprains being the most regular ankle injury and metatarsal fractures the most frequent foot injury. These injuries occur more often during football matches than ...
Successful ground-to-satellite laser communications applying next-generation error correction codes, mitigating atmospheric turbulence
2025-10-22
Abstract
The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.) and the Nagoya Institute of Technology (NITech, President: OBATA Makoto), collaborated with the Japan Aerospace Exploration Agency (JAXA), have achieved the world’s first successful demonstration of next-generation error correction codes, mitigating the impact of atmospheric turbulence on ground-to-satellite laser communications.
Atmospheric turbulence in ground-to-satellite laser links is known to cause fading, resulting in burst data errors. Error correction codes are one of the key technologies to mitigate such effects. In this experiment, ...
Photosynthesis without the burn
2025-10-22
Too much sun can ruin a day at the beach. It can also ruin photosynthesis, scorching plants and other organisms that depend on capturing sunlight for energy. Beneath the waves, though, algae have found a clever shield. Osaka Metropolitan University researchers and their colleagues discovered that a pigment called siphonein helps marine green algae keep photosynthesis humming, without the burn.
Photosynthetic organisms rely on delicate light-harvesting complexes (LHCs) to capture sunlight for energy. During photosynthesis, chlorophyll absorbs light and enters an excited ...
Not hunters but collectors: the bone that challenges the ‘humans wiped out Australian megafauna’ theory
2025-10-22
New research led by UNSW Sydney palaeontologists challenges the idea that indigenous Australians hunted Australia’s megafauna to extinction, suggesting instead they were fossil collectors.
The research published today in the journal Royal Society Open Science, opens in a new window focuses on the fossilised tibia (lower leg bone) of a now-extinct, giant ‘sthenurine’ kangaroo. Found in Mammoth Cave in southwestern Australia around the time of the First World War, the bone was later determined to be hard evidence, opens in a new window showing that Indigenous Australians hunted megafauna.
Renowned palaeontologist and expert on Australia’s ...
Discovery of new mechanism concerning plasma confinement performance
2025-10-22
Around the world, research is advancing to efficiently confine fusion plasma and harness its immense energy for power generation. However, it is known that turbulence occurring at various scales within the plasma causes the release of plasma energy and constituent particles, degrading the confinement performance. Elucidating this physical phenomenon and suppressing performance degradation is critically important. Particularly in the high-temperature plasma experiments currently conducted worldwide, micro-scale (just a few centimeters) turbulent eddies forming at various locations within the plasma significantly impact this confinement ...
