New research shows the connection between adverse childhood experiences (ACEs), such as physical or emotional abuse, and an increased risk of people growing up to be abusive against older generations. While generational trauma is known to be passed down from parent to child, the study showed that it can also reverberate upwards from parent to older generations. A survey of over 13,000 people in Japan found that about half had one or more ACEs. Of these, 8.5% self-reported committing some form of physical or verbal abuse against people aged over 65. An important contributing factor was the person’s mental and physical health, both of which are known to be affected by ...

Tsukuba, Japan—Acute kidney injury (AKI) is associated with a poor prognosis, and no effective treatment has been established to date. Understanding the mechanisms that prevent the progression of AKI is crucial. In AKI, immune cells known as macrophages produce lipid mediators (LMs), which are lipids with significant physiological activity and play a pivotal role in promoting and suppressing inflammation. Thus, elucidating their function is of paramount importance. In this study, researchers focused ...

Tsukuba, Japan—Hot springs frequently contain water that originates from rocks within the Earth's crust. This can be confirmed through isotopic analysis. Arima Hot Springs, located in Kobe, Hyogo Prefecture, Japan, exhibit unique characteristics, including salinity that is more than twice that of seawater, indicating that their water likely originates from the Philippine Sea Plate. However, a direct evidence supporting this connection is lacking. In this study, researchers confirmed that the isotopic ratios of plate-derived water beneath Arima Hot Springs, as predicted by a numerical model, agreed with those of nonmeteoric water components found ...

Tsukuba, Japan—Online communication tools are intended to bring people closer together. However, they often fail to sufficiently meet the human need for fulfilling social interactions. What is missing is a sense of social presence, that is, a "sense of being present with another person." This sense of social presence can be felt during mediated interactions, such as when using web conferencing tools or playing video games. Researchers at the University of Tsukuba have identified a method for augmenting the sense of social presence in online interactions through the sharing of biosignals. Biosignals such as heart rate can ...

Tsukuba, Japan—Sexual reproduction, a common mode of reproduction among numerous species, involves gametogenesis in which offspring are produced through fertilization, conjugation, or mating. In plants and animals, eggs and sperm differentiate from germ cells to form gametes. However, in budding yeast, spores are produced within diploid cells. During this process, de novo membrane structures form within the cytosol, encapsulating the meiotic haploid nuclei to produce spores. Despite this knowledge, the precise mechanism underlying the formation of these nascent membrane structures remains poorly understood. To ...

Kombucha is a fizzy, tangy drink made by fermenting tea. But brewers are now fermenting other plant-based drinks to explore nutritional properties and flavors. Researchers in ACS Agricultural Science & Technology compared the biochemistry and flavor of kombucha with brews made from apple and passion fruit juices. They found that the apple beverage contained high levels of bioactive compounds called flavonoids and ranked highly among taste testers, signaling its promise as a kombucha alternative. To make kombucha, brewers ferment sweetened tea with a spongy disk of microbes known as a SCOBY, or symbiotic culture of bacteria and yeast. The ...

A new PeerJ Life & Environment study has revealed that sloths, the famously slow-moving creatures of Central and South America, may face existential threats due to climate change. The research, conducted by scientists studying the metabolic response of sloths to rising temperatures, suggests that the energy limitations of these animals could make survival untenable by the end of the century, particularly for high-altitude populations. The study, titled "Sloth Metabolism May Make Survival Untenable Under Climate Change Scenarios," investigates how two-fingered sloths (Choloepus hoffmanni), living in both highland and lowland regions, ...

A new study has mapped out the gravitational “basins of attraction” in the local Universe, offering fresh insights into the large-scale cosmic structures that shape the movement of galaxies. Using advanced data from the Cosmicflows-4 compilation of distances and velocities of roughly 56,000 galaxies, the international research team applied cutting-edge algorithms to identify regions where gravity dominates, such as the Sloan Great Wall and the Shapley Supercluster. This research suggests that our Milky Way most probably resides within the larger Shapley basin, shifting ...

New Stanford-led research reveals how water systems, from desalination plants to wastewater treatment facilities, could help make renewable energy more affordable and dependable. The study, published Sept. 27 in Nature Water, presents a framework to measure how water systems can adjust their energy use to help balance power grid supply and demand. “If we’re going to reach net zero, we need demand-side energy solutions, and water systems represent a largely untapped resource,” said study lead author Akshay Rao, an environmental engineering PhD student in the Stanford School of Engineering. ...

It is widely recognized that finance is one of the critical enablers of accelerating climate action. However, renewable energy deployment (particularly in developing countries) requires more financing than fossil fuel-based alternatives due to a combination of factors, such as higher upfront investment costs. This means that finance itself can become a barrier to mitigation investment, which is particularly problematic in the context of energy justice—making renewable energy more widely accessible in low-income countries and communities.  A new international research effort led by CMCC scientists tackles this issue ...
