All-solid-state batteries (ASSBs) using silicon (Si) anodes are among the most promising candidates for high-energy and long-lasting power sources, particularly for electric vehicles. Si can store more lithium than conventional graphite, but its volume expands by roughly 410% during charging. This swelling generates mechanical stress that cracks particles and weakens their contact with the solid electrolyte, disrupting the flow of ions and reducing efficiency. To address this, a research group led by Professor Yuki Orikasa from the College of Life Sciences, Ritsumeikan University, ...

A researcher from the University of Tokyo and a U.S.-based structural engineer developed a new computational form-finding method that could change how architects and engineers design lightweight and free-form structures covering large spaces. The technique specifically helps create gridshells, thin, curved surfaces whose members form a networked grid. The method makes use of NURBS surfaces, a widely used surface representation format in computer-aided design (CAD). It also drastically reduces computation cost — a task that previously took 90 hours on a high-end GPU completes in about 90 minutes on a standard CPU. Architects pay particular attention to surfaces capable of supporting ...

Macrolactones—large ring lactones—are core components of many natural products and pharmaceutical agents. Traditional synthetic routes rely on seco acids activated with condensing reagents, often requiring harsh conditions or multi-step procedures. An alternative approach using hydroxyaldehydes has remained limited, and radical-based macrolactonization of these substrates had never been reported.   Now, a research team led by Dr. Kenta Tanaka, Assistant Professor at the Research Institute for Interdisciplinary ...

Iron (Fe) is an essential micronutrient for the healthy growth of plants, including many staple crops like rice. Its deficiency remains a common agricultural problem that slashes crop yields, as it leads to impaired photosynthesis, respiration, and nitrogen metabolism. Thus, establishing mechanisms to ensure crops can efficiently take up and utilize Fe, especially in alkaline soils, is a high-stakes challenge for global food security.   Getting Fe into the roots is only the first step; the mineral must then be properly distributed throughout the plant, especially to its young leaves, developing grains, and other active growth tissues. This process ...

During a baby’s early months, the brain is developing rapidly. Billions of neural connections form, expand, and are pruned back, shaped by genetics, the environment, and timing. Though brain development continues throughout life, the early months are critical, particularly when it comes to interactions between a parent and child. What could scientists learn from high-quality brain function data during infancy? With a new $2.3 million, four-year grant from the National Institute of Biomedical Imaging and Bioengineering, part of the National ...

PULLMAN, Wash. — College students who binge drink may be acting on influences they brought from home, a new Washington State University-led study suggests. A recent survey shows that students who binge drink more than other students tend to have grown up in a home with more permissive attitudes toward drinking. Those students are also more likely to join Greek-affiliated organizations like fraternities or sororities. In a study published in the journal Behavioral Sciences, researchers surveyed parents and students about drinking attitudes ...

In hydrogen production catalysts, water droplets must detach easily from the surface to prevent blockage by bubbles, allowing for faster hydrogen generation. In semiconductor manufacturing, the quality of the process is determined by how evenly water or liquid spreads on the surface, or how quickly it dries. However, directly observing how such water or liquid spreads and moves on a surface ('wettability') at the nanoscale has been technically almost impossible until now, forcing researchers to rely mostly on conjecture. KAIST announced on ...

For many of us, any kind of shopping is stressful enough. The anxiety, however, really kicks in when you must purchase something you’re going to share with another person. Such are the findings of a UC Riverside School of Business study published in the Journal of Marketing Research that compared consumer anxiety levels stemming from different shopping circumstances. Shopping for goods or services that you will share is significantly more stressful than shopping for yourself or for something to be given to another person, explained study co-author Margaret Campbell, an associate dean, professor, and chair of the school’s ...

HONOLULU, Dec. 2, 2025 — Some music is for grooving: It evokes spontaneous dancing, like head bopping, jumping, or arm swinging. Other music is for swaying, or for crying, or for slow dancing. Music makes people move, but whether musicians intentionally induce specific movements with their compositions, such as vertical bouncing or horizontal swaying, or what musical features would contribute to these distinctions, is more complex. Shimpei Ikegami, an associate professor at Showa Women’s University, sought to understand how musicians express intended bodily movement ...

HONOLULU, Dec. 2, 2025 — Wildlife poaching remains a major conservation concern. Technological advancements have enabled webs of acoustic sensors to be deployed throughout rainforests, creating the possibility of real-time alerts to the sounds of gun-based poaching. But the belly of the rainforest is loud, and sorting through a constant influx of sound data is computationally demanding. Detectors can distinguish a loud bang from the whistles, chirps, and rasps of birds and bugs. However, they often conflate the sounds of branches cracking, trees falling, or water dripping ...

An updated Cochrane review has found that calcium supplementation has no effect on pre-eclampsia, challenging long-held assumptions about the role of calcium in preventing hypertensive disorders in pregnancy. Researchers from Stellenbosch University have found strong evidence from large trials that calcium supplementation during pregnancy does not reduce the risk of pre-eclampsia. Pre-eclampsia is a life-threatening condition that can affect women in the second half of their pregnancy. It can be fatal or cause lifelong complications for both mother and baby. Pre-eclampsia is characterised by new onset high blood pressure with end-organ injury. The only ...

HOUSTON – (Dec. 2, 2025) – Tracking how genes switch on and off in the brain is essential for understanding many neurological diseases, yet the tools to monitor this activity are often invasive or unable to capture subtler changes over time. One emerging alternative is to use engineered serum markers ⎯ small proteins produced by targeted brain cells that can travel into the bloodstream, where they can be measured with a simple blood test. Referred to as released markers of activity, or RMAs, ...
