It might be less visible than dwindling lion populations or vanishing pandas, but the quiet crisis of small mammal extinction is arguably worse for biodiversity. These species are crucial indicators of environmental health, but they can be very hard to monitor, and many species with very different ecological niches look almost identical. But now scientists have developed a new way of identifying and monitoring these tiny mammals using their footprints, ...

From subarctic to subtropical, Japan’s varied climates present a challenge for energy-saving housing design. Adding the projected effects of climate change, with temperatures estimated to rise from 1.5 to 3.5°C by the close of the century, there currently is not a standard, one-size-fits-all solution. Therefore, climate-based building design solutions that consider regional differences, thermal comfort, and net-zero carbon goals are urgently needed. In ...

Gifu University scientists have uncovered how a brain-specific enzyme reshapes protein-linked sugar chains to facilitate the formation of complex glycans essential for normal brain function. These insights could inform future research into glycan-related brain disorders and open new avenues for therapeutic investigation. The study was published in the Journal of Biological Chemistry on Jan. 7. Proteins in the brain are modified by O-mannose glycans, specialized sugar chains that play key roles in neural structure ...

“Why can’t plasmons achieve quality factors as high as dielectrics?” “Because metals heat up easily—they’re inherently lossy.” This exchange is almost inevitable whenever plasmonic nanostructures come up in a discussion. Now, researchers from the Singapore University of Technology and Design (SUTD) and international collaborators have shown that this long-held limitation is not as fundamental as once believed. The research team has demonstrated a powerful new ...

A new review including over 100 clinical trials has found that no induction method was clearly effective than low-dose vaginal misoprostol, although some methods were less effective and safety profiles varied. Induction of labour involves initiating labour using pharmaceutical or mechanical methods. It’s common in obstetrics, particularly when there are health risks for the mother and baby or when pregnancies go beyond 42 weeks. Many induction methods exist, but the evidence behind them has previously been fragmented and unclear. The review compared 13 different methods of induction using a statistical technique called ...

The adverse health impacts associated with emissions across the full life cycle of plastics could double by 2040 unless immediate action is taken, new research suggests. The research identified health harms at every stage of the life-cycle of the plastics we use: from the extraction of fossil fuels, the feedstocks for more than 90% of plastics, and material production to their eventual disposal or release to the environment. The study team, led by researchers at the London School of Hygiene & Tropical Medicine (LSHTM) with colleagues from the University of Toulouse and the University of Exeter, used modelling ...

Prompt, individual-based dose assessment is essential to protect people from the negative consequences of radiation exposure after large-scale nuclear or radiological incidents. However, traditional dosimetry methods often require expensive equipment or complex laboratory analysis. Now, researchers at Hiroshima University have developed a cost-effective, portable dosimetry system that can provide immediate on-site readings using radiochromic film and a smartphone.

Menopause is linked to reductions in grey matter volume in key brain regions as well as increased levels of anxiety and depression and difficulties with sleep, according to new research from the University of Cambridge. The study, published today in Psychological Medicine, found that hormone replacement therapy (HRT) does not appear to mitigate these effects, though it can slow the decline in reaction times. Menopause is a key period in a woman’s life when her periods stop, due to lower hormone levels. It typically affects women between the ages of 45 and 55, during which time they ...

An international group of experts has developed new guidelines to help veterinarians better recognize and diagnose canine cognitive dysfunction syndrome (CCDS), commonly known as canine dementia. The condition affects many older dogs and can cause changes in behavior, sleep, learning, and daily routines, yet it is often overlooked despite its significant impact on animal welfare. The guidelines also highlight that research on canine dementia has the potential to contribute to our understanding of human dementia, particularly Alzheimer’s disease. Many dogs older than eight years show signs of cognitive dysfunction, which are ...

Salt is usually something people are warned to limit in food, not drinking water. But a global analysis suggests sodium in tap water may be an overlooked contributor to high blood pressure, particularly in coastal regions.  The study, published in BMJ Global Health, found that higher salinity in drinking water was associated with higher blood pressure and an increased risk of hypertension.  The research was led by Florida International University scientists, including Rajiv Chowdhury, chair of the Department of Global Health at FIU’s Robert Stempel ...

MSU has a satellite uplink/LTN TV studio and Comrex line for radio interviews upon request. People experience psychosis when they lose touch with reality.
