Artificial light influences the behaviour of many nocturnal animals such as bats, which are very sensitive to all types of lighting. Particularly critical is the illumination of natural caves in which bats roost. Cave illumination is widespread in tourist areas worldwide and disturbs the animals in their resting places.
With the launch of wearable devices and smartphones that require high capacity of electricity such as foldable phones and 5G phones, the interest in batteries are increasing and various battery types are developed. For example, flexible batteries embedded in the mobile watch band or wireless power sharing batteries that have developed from wireless charging. However, there is no manufacturing of a battery that produces a battery with thousands milliamp Hour (mAh) capacity to be foldable.
WASHINGTON, D.C., December 10, 2019 -- Scientists at the University of Illinois have created sugar cube-sized blocks of an electromagnetic material with potential to transform communication networks.
Sharing preferences for end of life care, known as advance care planning, may be linked to longer survival in terminally ill patients, suggests the first study of its kind, published online in the journal BMJ Supportive & Palliative Care.
Advance care planning enables adults to discuss wishes and priorities for their care, including stopping treatment to prolong life, when they are no longer able to do so.
But it's not known what impact this might have on survival in patients who are terminally ill.
WASHINGTON, D.C., December 10, 2019 - Thrips are tiny insects 2 millimeters long, about as long as four human hairs are thick. Thrips are known for their unwelcome ability to devour garden plants and, lately, to inform the design of microrobotics.
Researchers have found that transfusions using fresh red blood cells--cells that have spent seven days or less in storage--are no more beneficial than older red blood cells in reducing the risk of organ failure or death in critically ill children. The findings, the researchers said, should reassure doctors that the standard practice of using older red cells is just as safe and effective in these children, who are among the sickest and most fragile of patients.
New research strongly suggests that the distinct 'oxygenation events' that created Earth's breathable atmosphere happened spontaneously, rather than being a consequence of biological or tectonic revolutions.
The University of Leeds study, published in the journal Science, not only shines a light on the history of oxygen on our planet, it gives new insight into the prevalence of oxygenated worlds other than our own.
As the cut flower industry hits one of its busiest periods, new research has shown that the water-absorbing green floral foam used by florists is contributing to the world's microplastic problem.
A study by RMIT University published in Science of the Total Environment found the plastic foam, which breaks into tiny pieces, can be ingested by a range of freshwater and marine animals and affect their health.
The picture of sea otters frolicking among kelp beds and rocky shoals has become an iconic image of the California coastline. But it may be drawing attention away from the value of other habitat that could truly help the endangered species in its recovery - estuaries.
In fact, a new study released today concludes that California could more than triple its population of southern sea otters, from an estimated 3,000 to nearly 10,000, by repopulating the largest estuary on the coast - the San Francisco Bay.
Snowstorms can wreak havoc across the United States, but especially on the East Coast. Snow is the least-understood form of precipitation, with major snowstorms among the most difficult weather events to forecast. Yet people rely on these forecasts to stay safe, plan travel routes and decide whether to close schools or businesses.
Barcelona, 10 December 2019. A team led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by "la Caixa", has carried out a study to identify lifestyle habits that influence the risk of overweight and obesity in children. Of the behaviours analysed in the study, television watching had the strongest association with overweight and obesity.
The identification of natural carbon sinks and understanding how they work is critical if humans are to mitigate global climate change. Tropical coastal wetlands are considered important but, so far, there is little data to show the benefits. This study, led by the University of Göttingen with the Leibniz Centre for Tropical Marine Research in Bremen, and the University of Bremen showed that mangrove ecosystems need to be conserved and restored as part of the battle against rising carbon levels in the atmosphere. The research was published in Global Change Biology.
Magazine adverts continue to tell mothers to put caring for their families front and centre - and encourage them to devote all their knowledge to protecting and caring for them rather than for their own benefit or professional advancement.
A study of adverts in women's magazines since the 1950s found they present mothers with an idealised image of the 'knowing mother', where they are exhorted to put all their expertise to use in service to the family.
A previously unknown mechanism that suppresses satiety signals from the small intestine is the main finding of a new study. This may explain, first, satiety disorders in obesity and diabetes and, second, the prompt health effects of gastric bypass, a form of bariatric surgery.
Depending on the shape and orientation of their edges, graphene nanostructures (also known as nanographenes) can have very different properties - for example, they may ex-hibit conducting, semiconducting or insulating behavior. However, one property has so far been elusive: magnetism.
