The threat to insects and other small creatures from rainforest clearance and the consequences for the environment in tropical regions are recognised. What has not been studied so far is whether, and how, the oil palm plantations are able to sustain the populations of tiny below-ground animals that work to keep the soil healthy. In a new study led by the University of Göttingen, scientists have discovered high levels of biological activity in regions above ground level that may serve as oases for soil organisms.
Innovative, Indigenous-led health care partnerships and cultural healing practices have shown improved health outcomes and access to care, and have become important features of the medical landscape in Canada, according to a new analysis in CMAJ (Canadian Medical Association Journal).
Indigenous-led heath care partnerships incorporate traditional Indigenous knowledge as key in their approach to treatment and healing for Indigenous patients.
A practice article provides 5 things to know on how drugs can interact with cannabinoids in CMAJ (Canadian Medical Association Journal).
1. The antifungal drug ketoconazole was shown to nearly double cannabinoid levels. Similar effects might be seen with commonly used drugs, such as macrolide antibiotics, increasing the chance of cannabinoid-related adverse effects.
2. Cannabinoids can affect levels of other drugs, increasing levels and the risk of adverse effects.
Cases of potentially deadly brain damage as a result of stroke could be reduced after new research identified a pathway in the brain that causes swelling, and which responds to an innovative treatment.
Research led by the University of Exeter, and published in Nature Communications, has discovered how a malfunction in the way key proteins are transported within the brain after a stroke can lead to swelling, which can cause severe damage.
Researchers from Chalmers University of Technology, Sweden, have made a new contribution to the ongoing search into the possibility of life on Titan, Saturn's largest moon. Using quantum mechanical calculations, they have shown that azotosomes, a proposed alternative to cell membranes, could not form under the conditions there. Their research is published in the journal Science Advances.
MINNEAPOLIS - Older people who experience daytime sleepiness may be at risk of developing new medical conditions, including diabetes, cancer and high blood pressure, according to a preliminary study released today that will be presented at the American Academy of Neurology's 72nd Annual Meeting in Toronto, Canada, April 25 to May 1, 2020.
The condition called hypersomnolence is defined as excessive daytime sleepiness even after having seven or more hours of sleep. It can be debilitating for some people, affecting the way that they perform at work and in other daily activities.
A study out of Mississippi State University evaluated the impact insect pest management strategies have on the economic return of small-scale tomato production. The results of this evaluation are published in the article "Economic Effect of Insect Pest Management Strategies on Small-scale Tomato Production in Mississippi" in the open access online journal HortTechnology.
Humans began developing a complex culture as early as the Stone Age. This development was brought about by social interactions between various groups of hunters and gatherers, a UZH study has now confirmed. The researchers mapped the social networks of present-day hunter-gatherers in the Philippines and simulated the discovery of a medicinal plant product.
Ultrafast, multidimensional spectroscopy unlocks macroscopic-scale effects of quantum electronic correlations.
Researchers found that low-energy and high energy states are correlated in a layered, superconducting material LSCO (lanthanum, strontium, copper, oxygen).
Exciting the material with an ultrafast (
The strong correlation between the energy of this coherence and the optical energy of the emitted signal indicates a coherent interaction between the states at low and high energy.
It is a spectacular butterfly breed with an intriguing back story ... now scientists have revealed how male-killing bacteria are helping to create a dazzling hybrid of the African monarch.
Researchers have shed new light on the complex reproductive process which dictates that only female offspring of the Danaus chrysippus survive - all in close proximity to Kenya's capital, Nairobi.
The balance between weight gain and weight gain loss is predominantly determined by what you eat, how much you eat, and by how much exercise you get. But another important factor is often neglected... Published February 27 in the open-access journal PLOS Biology, research conducted by Kevin Kelly, Owen McGuinness, Carl Johnson and colleagues of Vanderbilt University, USA shows that it's not just how many calories you eat, but WHEN you eat them that will determine how well you burn those calories.
Like many poisonous animals, the African monarch butterfly's orange, white and black pattern warns predators that it is toxic. Warning patterns like this are usually consistent across individuals to help predators learn to avoid them. However, a recent study, published February 27 in the open-access journal PLOS Biology, shows how a population of African monarch butterflies (Danaus chrysippus) breaks this rule and has highly variable warning patterns.
New research suggests that companies looking to promote their latest environmentally friendly product should downplay its green credentials if they want consumers to buy it.
By highlighting green attributes through advertising, in some situations firms risk generating associations with weak product performance, say researchers from the University of East Anglia (UEA) and University of Leeds. This is because of the performance ability sometimes associated with green products, whereby consumers perceive them as being less effective.
Leesburg, VA, February 28, 2020--Although the imaging features of novel coronavirus disease 2019 (COVID-19) are variable and nonspecific, the findings reported thus far do show "significant overlap" with those of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), according to an ahead-of-print article in the American Journal of Roentgenology (AJR).
WHAT:
The emergence and rapid increase in cases of coronavirus disease 2019 (COVID-19), a respiratory illness caused by a novel coronavirus, pose complex challenges to the global public health, research and medical communities, write federal scientists from NIH's National Institute of Allergy and Infectious Diseases (NIAID) and from the Centers for Disease Control and Prevention (CDC). Their commentary appears in The New England Journal of Medicine.
