Hiroshima flooding: A case study of well usage and adaptive governance
Groundwater and multilevel cooperation in recovery efforts mitigated water crisis after flooding

Society is often vulnerable to disasters, but how humans manage during and after can turn devastation into opportunities for improved resilience.
For instance, private wells are attracting attention as an alternative resource for securing water for daily use and consumption in the event the water supply is cut off after a disaster. However, there are few records on how wells are used in the confusion of disasters, so detailed research is needed to promote the use of emergency wells.
Professor Takahiro Endo of the Graduate School of Sustainable System Sciences at Osaka Metropolitan University conducted a survey on the use of groundwater in Kure, Hiroshima Prefecture, during water supply disruptions due to the 2018 west Japan floods. The study examined actual implementation of adaptive governance, where multiple levels of government, nonprofits, and local individuals cooperate in achieving a desired societal outcome.
It was discovered that Hiroshima Prefecture, in agreement with the water quality inspection organization Hiroshima Environment and Health Association, had provided a free water inspection service for well owners after the water outage. This promoted the initiative to have the inspected wells open to the public. These collaborative efforts made it possible for wells to become available in a short period of time and supplemented the emergency water supply activities of local governments.
“This is a case of emergency water supply policy that makes use of the economic incentive of free water quality testing, which could be a model policy for other local governments considering the introduction of disaster wells,” stated Professor Endo.
These findings were published in Water International.

St. Petersburg, Fla - Welcoming a newborn is something many couples dream of doing, but it can get complicated when conceiving becomes a roadblock. Infertility affects one in six people, but obesity can also be a problem. When diet and exercise aren’t enough to lose weight, bariatric surgery can become an option. Yet a new national survey by Orlando Health finds that 56% of Americans do not know that bariatric surgery is an effective way to improve fertility.

Optical microscopy has long been a fundamental tool for scientific discovery. Yet, traditional far-field techniques are limited by diffraction, restricting their resolution to hundreds of nanometers, which can be inadequate for capturing phenomena in quantum and solid-state materials. With the emergence of tip-based microscopy capable of achieving atomic-scale spatial resolution, near-field optical nano-spectroscopy and nano-imaging have evolved into versatile tools for characterizing the optical properties of materials at the nanoscale. When further combined with ultrafast pump-probe ...

Communities exposed to drinking water contaminated with manufactured chemicals known as per- and polyfluoroalkyl substances (PFAS) experience up to a 33% higher incidence of certain cancers, according to new research from the Keck School of Medicine of USC.
The study, funded by the National Institutes of Health and just published in the Journal of Exposure Science and Environmental Epidemiology, is the first to examine cancer and PFAS contamination of drinking water in the U.S.
PFAS, which are used in consumer products such as furniture and food packaging, have been found in about 45% of drinking water supplies across the United States. ...

Girolline, a compound extracted from the sea sponge Pseudaxinyssa cantharella, has been investigated for possible antitumor effects and also found to have anti-malarial effects. Now, thanks to work by scientists from the RIKEN Center for Sustainable Resource Science, researchers have a better idea of how it works. In addition to its possible medicinal properties, the current findings suggest that the compound could also be useful as a chemical probe for research in areas such as aging and mitochondrial health.
GIrolline is one of a number of compounds with biological functions that were isolated from Pseudaxinyssa ...

Older Australian women are challenging traditional views of aging, embarking on solo road trips and travelling the country in search of adventure, personal growth and new horizons.
Equipped with a caravan, campervan, or a sturdy 4WD and a tent, these women are navigating vast landscapes, from the dusty Oodnadatta Track to the spectacular Tasmanian wilderness.
Margaret Yates, a PhD candidate from the University of Technology Sydney (UTS) Faculty of Health and a retired nurse, interviewed 29 women travellers to explore their motivations and experiences. The majority were over sixty and considered themselves ...

There has been a shift away from the use of more reliable hormonal methods of contraception to less reliable fertility awareness methods among women requesting abortion in England and Wales over the past 5 years, reveals research published online in the journal BMJ Sexual & Reproductive Health.
Use of the Pill, mini Pill, implants, patches, and vaginal rings has given way to more ‘natural’ methods, such as period tracking apps that highlight monthly peak fertility/ovulation, the findings ...

Implementing bans on the advertising, promotion, and sponsorship of tobacco products is linked to 20% lower odds of smoking, and 37% lower risk of taking up the habit, reveals a pooled data analysis of the available research, published online in Tobacco Control.
The findings indicate that these bans do influence behaviour, lending further weight to calls for their wider international implementation and enforcement, conclude the researchers.
In 2019 alone, more than a billion people around the globe regularly smoked tobacco, and smoking caused nearly 8 million deaths, note the researchers.
To curb the toll ...

A vascular ‘fingerprint’ on the light sensitive tissue layer at the back of the eye—the retina—can predict a person’s risk of stroke as accurately as traditional risk factors alone, but without the need for multiple invasive lab tests, finds research published online in the journal Heart.
The fingerprint, comprising 29 indicators of vascular health, is a practical and readily implementable approach that is particularly well suited for primary healthcare and low-resource settings, conclude the researchers.
Stroke affects around 100 million people around the globe and ...
