Humans negatively impact the health of grizzly bear populations through top-down influences like direct mortality associated with forestry roads (from conflict or illegal killings) and displacement from high quality habitats, and through bottom-up influences like reducing availability of food resources. Research published in Wildlife Monographs reveals the relationship between these forces, informing a strategic conservation program. Investigators radio-collared and followed numerous grizzly bears over multiple years in southeastern British Columbia. They found an interesting interplay between the most important bottom-up factor, ...

Patients living with fibromyalgia (FM) – a disease that predominantly affects women and is characterized by chronic pain, fatigue and brain fog – often find limited treatment options and a scarcity of explanations for their symptoms. Research led by Mass General Brigham investigators has found that cognitive behavioral therapy (CBT) can significantly reduce the burden of FM by, in part, reducing pain-catastrophizing, a negative cognitive and emotional response that can intensify pain through feelings of helplessness, rumination and intrusive thoughts. This finding is backed by neuroimaging ...

A new paper in Genome Biology and Evolution, published by Oxford University Press, shows that rapid evolution in bats may account for the animals’ extraordinary ability to both host and survive infections as well as avoid cancer.  Bats are exceptional among mammals for not only their ability to fly but also their long lives, low cancer rates, and robust immune systems. Bats are also thought to have played a role in the emergence of SARS-CoV-2. The ability of bats to tolerate viral infections may stem from unusual features ...

【Summary】 　A research group led by Professor Kazuki Kurimoto and Assistant Professor Hiroki Ikeda from the Department of Embryology at Nara Medical University has developed a highly sensitive method for quantitative single-cell transcriptome analysis, which enables the precise examination of cells extracted from tissue sections using laser capture microdissection (LCM), and named the method DRaqL (Direct RNA recovery and quenching for LCM). Moreover, this method allows quantification of exon-exon junctions of mRNA. In an application of DRaqL to mouse ovarian sections, the research group established a predictive model for oocyte transcriptomes based on their diameter. Remarkably, ...

As climate change accelerates, it is becoming increasingly important to study the impact of climate change on human health. A new thesis from the University of Gothenburg examines church records and historical weather data in the Nordic countries to show that the risk of dying from malaria was higher if the previous summer was a hot one. The growing impact of climate change on human health is an acute global threat in the 21st century. The rise in certain types of extreme weather events is not only affecting individuals, but also putting ecosystems that are closely linked to our health under pressure. “As the climate grows warmer, there is a risk of insect-borne ...

Over the past two decades, coral reefs have declined at unprecedented rates. This is in part because of extreme weather events, which cause wide-spread coral bleaching, a process during which corals lose their color because of stressors, including changes in water temperature, light, or nutrient availability. One of the worst mass bleaching events occurred in 2016 and 2017 on the Great Barrier Reef, causing bleaching on 91% of the system’s reefs. As frequency and severity of mass bleaching events are expected to increase in the future, researchers are looking for ways to protect corals from excessive radiation and temperatures. As part of the Cooling and Shading ...

The diagnostic evaluation tool was published online Sept. 15 with an accompanying letter by co-authors in the journal World Psychiatry. The tool is the first structured technique to evaluate people who suffer from a condition first recognized in young people in Japan, but believed to be widely shared in people of all ages across the globe. Known as the Hikikomori Diagnostic Evaluation, or HiDE, the tool provides practical guidance and specific ...

One explanation for why some species decline is that human modifications make existing habitat unsuitable for them. For other species, these modifications are advantageous and make the habitat available for them to expand into. Researchers from the Max Planck Institute of Evolutionary Anthropology in Germany, and the University of California Santa Barbara and the University of Rochester in the USA investigated the role that increased habitat availability might have played. They compared the rapidly expanding great-tailed grackle with their closest relative, the boat-tailed grackle, who are not ...

More than half of volunteer community health care workers in 19 countries experience labor exploitation, including sub-minimum-wage pay and excess work hours, Mount Sinai researchers report in the first systematic review of the subject. The researchers focused on two-tiered or dual-cadre programs, in which salaried community health workers work alongside a volunteer group of community health workers. The study, published in Lancet Global Health on September 19, provides a global estimate of the presence, prevalence, and magnitude of labor ...

Multi-storey buildings are assembled over cautiously to withstand wind strengths, researchers have found. This is because there are several difficulties in estimating damping – the method of removing energy in order to control vibratory motion like noise and mechanical oscillation, accurately in high-rise buildings The findings, published today in the journal Structures, addresses the draw back and were compiled by a team at the University of Bristol who studied the damping and natural frequency characteristics of a 150 m tall building in London (UK) obtained from the full-scale wind-induced responses using a minimal monitoring system. In general, the response ...

Barcelona, Spain: Two out of the four internationally-recommended screening tools used by emergency medical services are inadequate for recognising sepsis, according to new research presented at the European Emergency Medicine Congress today (Wednesday).   Mrs Silke Piedmont, a health scientist at the Department of Emergency Medicine Campus Benjamin Franklin Charité – Universitätsmedizin Berlin (Germany), and her colleagues from the University of Magdeburg and Jena (Germany), analysed data on 221,429 patients who were seen by emergency medical services (EMS) in Germany in 2016 outside of the hospital setting. They found that only one out of four ...

Is it an eagle? A birdie? No, it’s a gator.  The Rosenblatt Lab at the University of North Florida has recently published a study finding that living on a golf course dramatically changes alligator feeding habits.  The study suggests that land use changes can significantly alter the feeding habits of large predators. Changes in habitat and prey availability caused gators living on golf courses to have different dietary patterns and access to different prey communities compared to those living in natural habitats. As ...
