In Japan, many municipalities have suffered from population decline due to low birth rates and an aging population. In 2022, the Japanese population over the age of 65 was 36.21 million, accounting for 28.9% of the total population. In addition, approximately 1,300 shrinking cities are within the 1,700 municipalities in Japan. Moreover, the large number of shrinking cities in Japan is unprecedented on a global scale. As a response to the low birthrate, the Japanese government is discussing “unprecedented” measures to reverse the decline, such as ...

A new Cochrane Review led by an Upstate Medical University professor has found that, compared with standard antibiotic treatment, stool transplantation can increase the number of people recovering from Clostridioides difficile (C. diff) infection, a condition which causes potentially life-threatening diarrhea. 77 percent of people who received a stool transplant did not experience reinfection within eight weeks, compared to 40 percent of those who received antibiotics alone. C. diff is a bacterium that can cause life-threatening diarrheal illness in individuals ...

Without action, the negative impact on children’s long-term brain development could have consequences for life. Lead researcher Prof John Spencer, from UEA’s School of Psychology, said: “Prior work has shown that poor air quality is linked ...

During the peak of the Covid-19 pandemic, a constant public fear was the rise of a new variant of the disease. Among the countless possibilities of a SARS-CoV-2 viral mutation, some were really alarming, such as Omicron, Delta, and Gamma. The strains with greater virulence and ability to invade the immune system are defined as variants of concern (VOCs), since they also have the potential to overwhelm the health system, increasing the number of admissions to intensive care units (UTIs). Recently published in the Intensive ...

Genetic markers such as fragment length polymorphisms (RFLP), simple sequence repeat (SSR), and single-nucleotide polymorphisms (SNPs) provide unique identifiers for individual organisms. This aids the identification of significant genetic variations in plants, allowing modern plant breeding to select superior crop varieties. Next-generation sequencing (NGS) has enhanced marker-assisted selection or backcross breeding of crops, which is the transfer a desired trait such into the favored genetic background of another. However, due to its expensive nature and extensive data processing requirements, NGS is not practical for screening large populations ...

Organic peroxy radicals (RO2) are important intermediates in the degradation of atmospheric volatile organic compounds (VOCs). RO2 not only participates in the chain cycles of atmospheric radicals and influences oxidizing capacity of the atmosphere, but also controls the formation of secondary pollutants. Under low NOx conditions, peroxy radicals react mainly with HO2 radicals, as well as with themselves, and their products tend to have low volatility easily entering the particulate phase. However, the associated double radical ...

AUGUSTA, Ga. (April 25, 2023) – The first in-human-study of a new immunotherapy that blocks a natural enzyme tumors commandeer for their protection was well tolerated by children with relapsed brain tumors and enabled many to have unexpected months of a more normal life, researchers say. “Our kids were by and large out of the hospital and going about their daily activities. They were in school, we had young adults who were in college living in a dorm on their own, taking their medicine on their own and coming to see us once a month,” says Theodore S. Johnson, MD/PhD, pediatric hematologist/oncologist ...

In the United States, depression and anxiety are on the rise in African Americans and the evidence suggests that racism is a contributing factor, creating a ripple effect on mental health. Janeé M. Steele Ph.D. and Charmeka S. Newton, Ph.D. are licensed mental health professionals and scholars who specialize in culturally responsive therapy. They say: “In the Black community there can be a real resistance to our own trauma – for example, if I wasn’t exposed to physical abuse, is it really that bad? “But this kind of systemic, permeating racism that exists all ...

It’s a dangerous world out there. From bacteria and viruses to accidents and injuries, threats surround us all the time. And nothing protects us more steadfastly than our skin. The barrier between inside and out, the body’s largest organ is also its most seamless defense. And yet the skin is not invincible. It suffers daily the slings and arrows of outrageous fortune, and it tries to keep us safe by sensing and responding to these harms. A primary method is the detection of a pathogen, which kicks the immune system into action. But new research from the lab of Rockefeller’s Elaine Fuchs, published in Cell, reveals an alternative protective ...

The promise of superconductivity for electrical power transmission and transportation has long been held back by high costs. Now researchers from the University of Houston and Germany have demonstrated a way to cut the cost and upend both the transit and energy transport sectors by using superconductors to move people, cargo and energy along existing highway infrastructure. The combined system would not only lower the cost of operating each system but would also provide a way to store and transport liquified hydrogen, an important ...

Polycyclic aromatic hydrocarbons (PAHs) are typical organic compounds found in cigarette smoke and vehicle exhaust. In addition, PAHs are produced from incomplete combustion of organic material and cooking. The highest concentrations of PM-bound PAHs ranged from 550 ng/m3 to 39000 ng/m3, were observed in Chinese kitchens, fire stations, and ships. Polycyclic aromatic hydrocarbons may combine with ultrafine particles (UFPs) in the air to form particle-bound PAHs. PM0.1 may adsorb large amounts of toxic organic compounds, and long-term exposure to indoor UFPs from cooking resulted in ...

An interdisciplinary team of researchers has developed a suite of tools to estimate the total economic value of improving water quality in urban streams. The work can assist federal and state agencies charged with developing environmental regulations affecting urban ecosystems across the Piedmont Region of the United States, which stretches from Maryland to Alabama. “Urban streams are ubiquitous and face a number of stressors from rapid economic development,” says Roger von Haefen, professor of agricultural and resource economics at North Carolina State University and corresponding ...

UNIVERSITY PARK, Pa. — An unusual blinking fish, the mudskipper, spends much of the day out of the water and is providing clues as to how and why blinking might have evolved during the transition to life on land in our own ancestors. New research shows that these amphibious fish have evolved a blinking behavior that serves many of the same purposes of our blinking. The results suggest that blinking may be among the suite of traits that evolved to allow the transition to life on land in tetrapods — the group of animals that includes mammals, birds, reptiles and amphibians — some 375 million years ago. The study appears the week ...

A new machine-learning method could help us gauge the time of our internal body clock, helping us all make better health decisions, including when and how long to sleep.   The research, which has been conducted by the University of Surrey and the University of Groningen, used a machine learning programme to analyse metabolites in blood to predict the time of our internal circadian timing system.     To date the standard method to determine the timing of the circadian system is to measure the timing of our ...

ANN ARBOR—Health surveys and clinical studies have a data collection problem: Because of the way they record sex or gender, they often exclude transgender and gender-diverse people, according to University of Michigan research.   Most studies and surveys either ask participants for their sex, a biological construct, or their gender, a social construct. In this way, they only consider either sex or gender independently or use the two concepts interchangeably, says Kate Duchowny, a research assistant professor in the Survey Research Center at the U-M Institute for Social Research.   Participants either respond with their sex assigned at birth or the ...

Scientists observed seismic waves traveling through Mars’ core for the first time and confirmed model predictions of the core’s composition.
