A new book, The Climate Pandemic: How Climate Disruption Threatens Human Survival, concludes that humans will not survive the unrelenting onslaught of climate disruption. The e-book is available free on Amazon March 1-5. “As horrific as the COVID-19 pandemic has been, its effects pale in comparison to the coming catastrophe from climate disruption,” wrote author and veteran science writer Dennis Meredith. “In fact, the climate pandemic will steadily worsen, even bringing our species to extinction, unless we launch a global revolution to abandon our carbon-dependent energy system. “Given the evidence in this book, I see only a vanishingly small possibility of ...

CHAMPAIGN, Ill. — A new book from University of Illinois Urbana-Champaign anthropology professor Kathryn Clancy takes an unflinching look at the many ways humans have struggled – and often failed – to understand one of the greatest mysteries of human biology: menstruation. In “Period: The Real Story of Menstruation,” Clancy first focuses on the myriad ways human societies, their leaders, scientists and health practitioners have gotten it wrong – from myths and taboos about the purpose and health effects ...

Researchers have discovered how a gene that increases the risk of developing genetic heart disease functions, paving the way for new treatments. The study, led by Murdoch Children’s Research Institute and published in Nature Cardiovascular Research, has  revealed a new pathway for how children and adults develop cardiomyopathy, a group of diseases that affect the heart’s ability to pump blood around the body.  Heart disease is the leading cause of death worldwide. Patients with cardiomyopathy, a form of heart disease ...

Taking vitamin D supplements may help ward off dementia, according to a new, large-scale study. Researchers at the University of Calgary’s Hotchkiss Brain Institute in Canada and the University of Exeter in the UK explored the relationship between vitamin D supplementation and dementia in more than 12,388 participants of the US National Alzheimer's Coordinating Center, who had a mean age of 71 and were dementia-free when they signed up. Of the group, 37 per cent (4,637) took vitamin D supplements. In the study, ...

Rounding checklists can help hospital care teams improve patient outcomes, and new research points to the potential for patient-specific checklists as a valid way to effectively translate the latest evidence into clinical practice. These checklists can be helpful tools during daily rounds when multidisciplinary members of the patient care team convene to discuss each patient’s status and care plan. If too complex or generic, the checklists may instead become a burden, taking up valuable time with minimal impact. One way to customize rounding checklists is to have an individual serve as a checklist prompter, listening to the conversation, eliminating ...

Research Highlights: In a study of U.S. military veterans, researchers noted that participating in home-based cardiac rehabilitation was associated with a 36% lower risk of death compared to veterans who chose not to participate in cardiac rehabilitation. Less than half of the study participants enrolled in rehabilitation, which focused on improving heart-healthy behaviors. The research may be the first U.S. study to provide evidence of living longer with home-based cardiac rehabilitation in people with heart disease.

Flamingos form cliques of like-minded individuals within their flocks, new research shows. Scientists analysed the personalities and social behaviour of Caribbean and Chilean flamingos. Birds of both species tended to spend time with others whose personality was similar to their own.   The study, by the University of Exeter and the Wildfowl & Wetlands Trust (WWT), reveals the complex nature of flamingo societies and could help in the management of captive flocks. “Our previous research has shown that individual flamingos have particular ‘friends’ within the flock,” said Dr Paul Rose, from WWT and Exeter’s Centre for Research in Animal Behaviour. “In ...

Toronto, ON — A new study published in the journal International Social Work has uncovered concerning rates of depression, post-traumatic stress disorder (PTSD) and anxiety among social workers. Stressors related to COVID-19 were the strongest factors associated with the negative mental health outcomes. Those who experienced a higher number of pandemic-related stressors — such as health concerns, increased caregiving responsibilities, violence in the home, family stress due to confinement, and stress associated with work-life balance — experienced mental health problems ...

The mainly brown woodcock uses its bright white tail feathers to communicate in semi-darkness, reflecting 30% more light than any other known bird. These surprise findings, by a team led by an Imperial College London scientist, suggest there is much to learn about how birds that are most active at night or at dawn and dusk communicate. Birds that are most active during the day often have colourful plumages, which they use to communicate information with each other. Birds that are most active at dawn and dusk or at night (‘crepuscular’), such as nightjars and woodcocks, tend to have less showy plumage, as while sleeping during ...

Cells that form cutaneous squamous cell carcinoma tumours prepare themselves to migrate to the lymph nodes to metastasise other organs, and they make changes so that they can survive this process. According to a study led by researchers from the Inflammatory and Neoplastic Dermatological Diseases Research Group at the Hospital del Mar Medical Research Institute, published in the journal Life Science Alliance, these cells stop consuming glucose so that they can survive by using LDL cholesterol molecules, the ...

Although cable locks – commonly distributed to prevent firearm injury and death – are included in many legal firearm purchases, research shows firearm owners rarely prefer or use these devices. But a Rutgers study published in Injury Epidemiology found that gun owners who were told about cable locks at the time they purchased the firearm were more than twice as likely to use locking devices than those who weren’t told about cable locks when they made these purchases. “Simply placing a cable lock in a bag when somebody purchases a firearm likely has minimal impact, but a simple discussion mentioning that a lock was included may make enough of an ...

One in ten early deaths could be prevented if everyone managed at least half the recommended level of physical activity, say a team led by researchers at the University of Cambridge. In a study published today in the British Journal of Sports Medicine, the researchers say that 11 minutes a day (75 minutes a week) of moderate-intensity physical activity – such as a brisk walk – would be sufficient to lower the risk of diseases such as heart disease, stroke and a number of cancers. Cardiovascular diseases – such as heart disease and stroke – are the leading cause of death globally, ...

The Pink-throated Brilliant hummingbird, Heliodoxa gularis, has, unsurprisingly, a brilliant pink throat. So does its cousin, the Rufous-webbed Brilliant hummingbird, Heliodoxa branickii. When scientists found a Heliodoxa hummingbird with a glittering gold throat, they thought they might have found a new species. DNA revealed a different story: the gold-throated bird was a never-before-documented hybrid of the two pink-throated species. John Bates, the senior author of a new study in the journal Royal Society Open Science reporting on the hybrid, first encountered the unusual bird while doing fieldwork in Peru’s Cordillera ...

Dementia with Lewy bodies (DLB), one of the most common forms of dementia, has no cure. Previous studies suggested that gut bacteria, the microorganisms that live in the human digestive tract, play a role in Parkinson’s disease, another neurodegenerative disorder, but the bacteria involved in DLB had not been identified. Now, a group led by researchers at the Nagoya University Graduate School of Medicine in Japan has identified three bacteria involved in DLB: Collinsella, Ruminococcus, and Bifidobacterium. Their findings, reported in npj Parkinson's ...

Greater numbers of Bison in Yellowstone National Park may come at a cost to the biological diversity of the important streamside habitats of the Park according to a new report in the journal Ecosphere Bison influences on composition and diversity of riparian plant communities in Yellowstone National Park.  Riparian areas (streamside zones) form the interface between terrestrial and aquatic ecosystems and are hotspots of biodiversity and productivity in the public lands of the Western USA.  The study findings are that ...

For those on keto or paleo diets, this may be tough to swallow. A new study from Tulane University which compared popular diets on both nutritional quality and environmental impact found that the keto and paleo diets, as eaten by American adults, scored among the lowest on overall nutrition quality and were among the highest on carbon emissions. The keto diet, which prioritizes high amounts of fat and low amounts of carbs, was estimated to generate almost 3 kg of carbon dioxide for every ...

Southern right whales adjusted their foraging grounds over the past 30 years as climate change altered where prey could be found, according to a University of Auckland, Waipapa Taumata Rau scientist. Dr Emma Carroll, of the School of Biological Sciences, was senior author of a paper which used data gleaned from contemporary whale skin samples along with whaling records stretching back to 1792. Over the past three decades, the whales increased their use of mid-latitude foraging grounds in the south Atlantic and southwest Indian oceans in the late summer and autumn, according to Carroll and dozens of collaborators including lead author Solène Derville, of Oregon State University. The ...

Long COVID is associated with reduced brain oxygen levels, worse performance on cognitive tests and increased psychiatric symptoms such as depression and anxiety, according to new research studying the impacts of the disease.   Researchers from the University of Waterloo combined the results of two new parallel studies: a laboratory study involving cognitive testing and imaging of oxygen levels in the brain, and a national population survey of Canadians in 2021 and 2022.  The laboratory study found that individuals who had experienced symptomatic COVID-19 illness performed worse on two computer tasks. One is measuring inhibition and another impulsive decision-making. ...

Stars are formed by molecular gas and dust coalescing in space. These molecular gases are so dilute and cold that they are invisible to the human eye, but they do emit faint radio waves that can be observed by radio telescopes. Observing from Earth, a lot of matter lies ahead and behind these molecular clouds and these overlapping features make it difficult to determine their distance and physical properties such as size and mass. So, even though our Galaxy, the Milky Way, is the only galaxy close ...

Conventional mechanics of materials books treat elastic deformations of solids through one-dimensional models for extension of rods, torsion of shafts and bending of beams. In functional materials, elastic, thermal, electric and magnetic fields interact. A systematic treatment of these fields and their interactions for one-dimensional models of extension, torsion and bending of beams in addition to the underlying three-dimensional theory is presented in new book, Mechanics of Functional Materials, by Professor of Mechanical and Materials ...
