The first large-scale study of the risks that countries face from dependence on water, energy and land resources has found that globalisation may be decreasing, rather than increasing, the security of global supply chains.
Countries meet their needs for goods and services through domestic production and international trade. As a result, countries place pressures on natural resources both within and beyond their borders.
ANN ARBOR, Mich. -- A growing number of demonstrators taking to the streets to protest police brutality and racial injustice may include teenagers, a new national poll suggests.
One in 12 parents say their teen has attended an event about racism or police reform this year, according to the C.S. Mott Children's Hospital National Poll on Children's Health at Michigan Medicine.
And while many parents are addressing the national issue with their children at home, the Mott Poll report indicates racial differences between families when it comes to these interactions.
EUGENE, Ore. - Oct. 23, 2020 - University of Oregon biologists have used the model organism Caenorhabditis elegans to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat.
Orono, Maine -- The Falkland Islands are a South Atlantic refuge for some of the world's most important seabird species, including five species of penguins, Great Shearwaters, and White-chinned Petrels. In recent years, their breeding grounds in the coastal tussac (Poa flabellata) grasslands have come under increasing pressure from sheep grazing and erosion. And unlike other regions of the globe, there has been no long-term monitoring of the responses of these burrowing and ground nesting seabirds to climate change.
PHILADELPHIA - Multiple sclerosis (MS) is an autoimmune disorder that develops as immune cells attack the nervous system. T cells are a critical part of our immune system, with a complex array of subtypes - some drive the autoimmune response, while others try to suppress it.
Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have discovered that neutrophils, the most abundant cells of the innate immune system, have many more functions in the body than previously thought. This finding suggests possible new treatments for many diseases, including cancer.
In a study published in the journal Cell, the research team demonstrate that neutrophils acquire new characteristics when they arrive in a tissue and that these specialized functions help to maintain organ health.
A strategy for giving intermittent, high doses of the anti-cancer drug sunitinib is well-tolerated by patients with advanced cancer and increases concentrations of the drug in tumours, which is associated with improved survival, according to research to be presented at the 32nd EORTC-NCI-AACR [1] Symposium on Molecular Targets and Cancer Therapeutics, which is taking place online.
Secondary forests play an important part in carbon capture because they tend to absorb a larger amount of carbon than they lose to the atmosphere. However, the size and average age of these often abandoned areas where vegetation grows back were unknown until now.
There is much debate surrounding the age of the Clovis -- a prehistoric culture named for stone tools found near Clovis, New Mexico in the early 1930s -- who once occupied North America during the end of the last Ice Age. New testing of bones and artifacts show that Clovis tools were made only during a brief, 300-year period from 13,050 to 12,750 years ago.
If you flew from the sea towards the land in the north slope of Alaska, you would cross from the water, over a narrow beach, and then to the tundra. From the air, that tundra would look like a landscape of room-sized polygonal shapes. Those shapes are the surface manifestations of the ice in the frozen ground below, a solidified earth known as permafrost.
Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a USC-led research team.
The researchers believe these metals could change the ocean ecosystem, though it's unclear whether it would be for better or worse.
The presence of insecticides in streams is increasingly a global concern, yet information on safe concentrations for aquatic ecosystems is sometimes sparse. In a new study led by Colorado State University's Janet Miller and researchers at the United States Geological Survey, the team found a common insecticide, fipronil, and related compounds were more toxic to stream communities than previous research has found.
A first-of-its-kind global survey shows the initial phase of the COVID-19 lockdown dramatically altered our personal habits, largely for the worse.
New research from Edith Cowan University (ECU) has revealed that training one arm can improve strength and decrease muscle loss in the other arm - without even moving it.
The findings could help to address the muscle wastage and loss of strength often experienced in an immobilised arm, such as after injury, by using eccentric exercise on the opposing arm.
Our hunger for energy is insatiable, it even continues to rise with the increasing supply of new electronic gadgets. What's more, we are almost always on the move and thus permanently dependent on a power supply to recharge our smartphones, tablets and laptops. In the future, power sockets (at least for this purpose) could possibly become obsolete. The electricity would then come from our own clothes. By means of a new polymer that is applied on textile fibers, jackets, T-shirts and the like could soon function as solar collectors and thus as a mobile energy supply.
