A species of frog endemic to the Pacific Northwest faces a 50 per cent increase in the probability of extinction by the 2080s due to climate change, according to a new study published by SFU researchers in the Ecological Society of America.
The mountain-dwelling Cascades frog thrives in extreme climatic conditions, ranging from dozens of feet of snow in winter to temperatures in excess of 90°F in summer. Cascades frogs are explosive breeders and their role as predators of flying insects is critical to aquatic and terrestrial ecosystems.
New Orleans, LA - Dr. Paul Harch, Clinical Professor and Director of Hyperbaric Medicine at LSU Health New Orleans School of Medicine, and Dr. Edward Fogarty, Chairman of Radiology at the University of North Dakota School of Medicine, report the first PET scan-documented case of improvement in brain metabolism in Alzheimer's disease in a patient treated with hyperbaric oxygen therapy (HBOT).
In a Pharmacology Research & Perspectives study of individuals living in Olmsted County, Minnesota from 2005-2012, potential overprescribing of antidepressant medications occurred in nearly one-quarter of elderly residents.
In a Developmental Science study of preschool-aged children, implicit and explicit evaluations of Black boys were less positive than evaluations of Black girls, White boys, or White girls.
This "gendered racial bias" was exhibited by both White and non-White children and was not correlated with their exposure to diversity. It also mirrors social bias observed in adults.
Augusta, Ga. (Jan. 24, 2019) - A free, simple screening for lung cancer can save a patient money, while building a healthy relationship for any medical needs they may have in the future. The research, published in the Annals of Thoracic Surgery, shows the partnership can be beneficial for patients looking for cardiology specialists, family medical care and other health-related issues, as well as for medical facilities that offer the free screening.
People are more likely to recover from shoulder pain if they have the confidence to carry on doing most things, despite their pain - according to new research from the University of East Anglia and University of Hertfordshire.
Researchers studied more than 1,000 people undergoing physiotherapy for shoulder pain.
They found that those who expected physiotherapy would help them were likely to recover more than those who expected minimal or no benefit.
CHAMPAIGN, Ill. -- Land conservation programs that have converted tens of thousands of acres of agricultural land in Illinois back to a more natural state appear to have helped some rare birds increase their populations to historic levels, a new study finds. Other bird species with wider geographic ranges have not fared as well, however.
Our microbiome, the complex community of bacteria, fungi, parasites, and other microorganisms in and on our bodies, reflects the way we live. If we own a pet, we likely share microbes with them. If we eat meat, the microbiome in our intestines may look different from that of a vegan.
After major global successes in the battle against malaria, the positive trend stalled around 2015 - apart from in Zanzibar in East Africa, where only a fraction of the disease remains. In a new study published in BMC Medicine, researchers at Karolinska Institutet in Sweden explain why this was and show that new strategies are needed to eradicate the disease. One of the problems is a change in mosquito behaviour and selection in the parasites.
The two seabird species unique to Hawaii, Newell's Shearwaters and Hawaiian Petrels, are the focus of major conservation efforts--at risk from habitat degradation, invasive predators, and other threats, their populations plummeted 94% and 78% respectively between 1993 and 2013. However, a new study in The Condor: Ornithological Applications offers hope of previously undetected colonies of these birds on the island of Oahu, from which they were believed to have vanished by the late 1700s.
New research has found that a novel Artificial Intelligence (AI) system can dramatically reduce the time needed to ensure that abnormal chest X-rays with critical findings will receive an expert radiologist opinion sooner, cutting the average delay from 11 days to less than 3 days. Chest X-rays are routinely performed to diagnose and monitor a wide range of conditions affecting the lungs, heart, bones, and soft tissues.
Researchers have developed a simple blood test that can detect when a newly transplanted lung is being rejected by a patient, even when no outward signs of the rejection are evident. The test could make it possible for doctors to intervene faster to prevent or slow down so-called chronic rejection--which is severe, irreversible, and often deadly--in those first critical months after lung transplantation. Researchers believe this same test might also be useful for monitoring rejection in other types of organ transplants.
Unlike animals, plants cannot move freely to escape from life-threatening conditions. This constraint means that they require strategies to protect themselves against the diverse stresses they encounter in their natural environments. These environmental stresses can be of a physical (abiotic) nature, such as drought and high salinity, or are biotic, such as attack from microbial pathogens and insect pests. The underlying protective mechanisms of plants involve inducible stress responses that are specialized to the respective stress.
The strange orbits of some objects in the farthest reaches of our solar system, hypothesised by some astronomers to be shaped by an unknown ninth planet, can instead be explained by the combined gravitational force of small objects orbiting the Sun beyond Neptune, say researchers.
ANN ARBOR, Mich. -- Vitamin C to keep the germs away. Never go outside with wet hair. Stay inside.
Despite little or no evidence suggesting these types of methods actually help people avoid catching or preventing a cold, more than half of parents have tried them with their kids, according to the C.S. Mott Children's Hospital National Poll on Children's Health at the University of Michigan.
