Determining proper subsidies for walking rewards

2025-11-13

(Press-News.org) The unforeseen consequences of modern lifestyles are coming to the forefront as healthcare costs spike in developed countries worldwide. One method to mitigate this is to encourage walking to promote good health. Therefore, initiatives to increase daily steps have been taking shape and becoming subjects for in-depth study.

Dr. Haruka Kato, a junior associate professor at Osaka Metropolitan University, with policy planners from the Sakai City Government investigated the effect of a train fare subsidy program on daily walking steps. A 7-week randomized controlled trial of 900 participants who used the HealthSmart-Senboku smartphone application was designed to investigate the steps of the following subgroups: prime-aged adults (20–49 years old), middle-aged adults (50–64 years old), and older adults (≥65 years old). This study subsidized the intervention group with either 2000 or 1000 points, which could be exchanged for digital train tickets worth 2000 JPY or 1000 JPY on the Senboku Rapid Railway.

The team found that the intervention group subsidized with 1000 points significantly increased daily walking steps by 711.43 steps/day for prime-aged adults. However, middle-aged and older adults in this group did not have significantly more steps than the control group. Similarly, the intervention group subsidized with 2000 points did not significantly change their daily walking steps across all age subgroups.

“These findings suggest that fare subsidy programs that encourage active travel require appropriate pricing,” said Dr. Kato, “Further, this provides important insights into the effectiveness of train fare subsidy programs for prime-aged adults.”

The findings were published in Research in Transportation Economics.

Two Keck Medicine of USC hospitals earn ‘A’ Leapfrog hospital safety grade

2025-11-13

LOS ANGELES — Keck Hospital of USC and USC Verdugo Hills Hospital (USC-VHH) each earned a Fall 2025 “A” Hospital Safety Grade from The Leapfrog Group, an independent national nonprofit focused on patient safety. The hospitals are part of Keck Medicine of USC, the University of Southern California’s health system. “This is the first time the health system has received two ‘A’s simultaneously, which is a huge accomplishment,” said Rod Hanners, CEO of Keck Medicine. “The Leapfrog Group grades hospitals ...

Systematic review of multimodal physiological signals from wearable sensors for affective computing

2025-11-13

Affective computing, proposed by Picard in 1997, aims to endow computational systems with the ability to recognize, interpret, and respond to human emotions. Early studies relied primarily on behavioral cues such as facial expressions and voice tone for modelling affective states. Affective computing has entered a new phase—wearable devices are capable of continuously acquiring multimodal physiological signals from multiple sensor channels that differ in terms of sampling frequency, physiological origin, and signal characteristics. In ...

Newly discovered predatory “warrior” was a precursor of the crocodile – and although it lived before the early dinosaurs, it looked just like one

2025-11-13

A newly discovered, carnivorous lizard ostensibly represents what most casual onlookers would perhaps perceive to be a dinosaur; however, it is in fact a precursor of the modern crocodile. Named Tainrakuasuchus bellator, partially derived from Latin meaning for “warrior” or “fighter”, this armour-plated reptile lived 240 million years ago just before the dinosaurs. And, as a Pseudosuchia (the precursors of modern crocodiles and alligators), it was among a group of the top, most dominant predators of its time in the Triassic Period. This particular new species – detailed, today, in the peer-reviewed Journal of Systematic Palaeontology – was approximately ...

Ultrathin gallium nitride quantum‑disk‑in‑nanowire‑enabled reconfigurable bioinspired sensor for high‑accuracy human action recognition

2025-11-13

As artificial vision systems evolve, bridging the gap between sensing and processing remains a key challenge. Now, researchers from the University of Science and Technology of China, led by Prof. Yong Yan and Prof. Haiding Sun, have developed a reconfigurable bioinspired vision sensor using GaN/AlN quantum-disk-in-nanowires (QD-NWs) that emulates the human retina’s dual-cell system—delivering in-sensor computing for high-accuracy human action recognition (HAR). Why This Bioinspired Sensor Matters Dual-Mode ...

First high-precision measurement of potential dynamics inside reactor-grade fusion plasma

2025-11-13

Nuclear fusion, which operates on the same principle that powers the Sun, is expected to become a sustainable energy source for the future. To achieve fusion power generation, it is essential to confine plasma at temperatures exceeding one hundred million degrees using a magnetic field and to maintain this high-energy state stably. A key factor in accomplishing this is the electric potential inside the plasma. This potential governs the transport of particles and energy within the plasma and plays a crucial role in establishing a state in which energy is effectively confined and prevented ...

Study: A cellular protein, FGD3, boosts breast cancer chemotherapy, immunotherapy

2025-11-13

CHAMPAIGN, Ill. — A naturally occurring protein that tends to be expressed at higher levels in breast cancer cells boosts the effectiveness of some anticancer agents, including doxorubicin, one of the most widely used chemotherapies, and a preclinical drug known as ErSO, researchers report. The protein, FGD3, contributes to the rupture of cancer cells disrupted by these drugs, boosting their effectiveness and enhancing anticancer immunotherapies. The discovery is described in the Journal of Experimental & Clinical Cancer Research. The new findings were the happy result of experiments involving ErSO, an experimental drug that killed 95-100% of estrogen-receptor-positive ...

Common gout drug may reduce risk of heart attack and stroke

2025-11-13

A widely-used, inexpensive gout drug could reduce heart attacks and strokes in people with cardiovascular disease, according to a new Cochrane review. The review examined the effects of low doses of colchicine, a drug used to treat gout, and found no increase in serious side effects. Cardiovascular disease is often driven by chronic low-grade inflammation, which contributes to recurrent cardiovascular events such as heart attacks and strokes. Colchicine has anti-inflammatory properties that make it a promising option for people with heart disease. A promising effect on cardiovascular risk The review included 12 randomized controlled trials involving nearly 23,000 ...

Headache disorders affect 3 billion people worldwide—nearly one in every three people, ranking sixth for health loss in 2023

EMBARGOED: Hold for release until Wednesday, Nov. 12 at 18:30 ET / 23:30 UK time Headache disorders affect 3 billion people worldwide—nearly one in every three people, ranking sixth for health loss in 2023 Women experienced more than twice the headache-related health loss of men and spent a greater share of their lives with headache symptoms. Migraine caused nearly 90% of all disability linked to headache disorders, even though tension-type headache was more common. More than one-fifth of the global headache burden ...

Mayo Clinic scientists create tool to predict Alzheimer's risk years before symptoms begin

2025-11-13

ROCHESTER, Minn. — Mayo Clinic researchers have developed a new tool that can estimate a person's risk of developing memory and thinking problems associated with Alzheimer's disease years before symptoms appear. The research, published in The Lancet Neurology, builds on decades of data from the Mayo Clinic Study of Aging — one of the world's most comprehensive population-based studies of brain health. The study found that women have a higher lifetime risk than men of developing dementia and mild cognitive impairment (MCI), a transitional stage between healthy aging and dementia ...

Extending anti-clotting treatment linked to lower rates of new clots

2025-11-13

Extending anti-clotting drugs beyond the initial treatment period of at least 90 days after a first blood clot is linked to lower rates of new clots developing compared with stopping treatment, finds a US study published by The BMJ today. Extended treatment was also linked to higher rates of major bleeding (a common side effect of anti-clotting drugs) but the authors say continued use results in an overall “net clinical benefit.” Guidelines recommend anti-clotting treatment for at least 3-6 months for patients with venous thromboembolism ...
