"A healthy community requires healthy soil." This idea spurred a consortium of researchers, farmers, and community garden practitioners to dive into the challenges--and opportunities--of urban agriculture. Their efforts, now in a second year, may highlight how urban soil can be a resource for human and environmental health.
The respiratory systems of Atlantic salmon function normally even when carrying large loads of piscine orthoreovirus (PRV), new UBC research has found.
"We didn't find significant harm to the fish's respiratory physiology despite the virus replicating to a load equal to, if not higher, than those seen naturally in wild or farmed fish" said Yangfan Zhang, a PhD student in UBC's faculty of land and food systems and lead author of the study published today in Frontiers in Physiology.
WASHINGTON -- In late 2018, the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft arrived at Bennu, the asteroid it will be studying and sampling over the next several years.
MISSOULA - New University of Montana research suggests climate change makes it increasingly difficult for tree seedlings to regenerate following wildfires in low-elevation forests, which could contribute to abrupt forest loss.
The study, "Wildfires and Climate Change Push Low-elevation Forests Across a Critical Climate Threshold for Tree Regeneration," was published March 11 in the Proceedings of the National Academy of Sciences and is available online at http://bit.ly/2HeZc8t.
ANN ARBOR--By slingshotting themselves forward, human cells can travel more than five times faster than previously documented.
University of Michigan researchers observed the movement in bioengineered 3D scaffolds that model stromal tissue--the connective tissue that surrounds organs.
The researchers say this method of cell movement, observed for the first time, could be involved in the spread of cancer. And in the future it could potentially be harnessed to direct the movement of healthy cells for tissue repair therapies.
Concussion researchers have long suggested that damage to the corpus callosum, a thick bundle of nerves that connects the brain's two halves, could result in some common side effects of concussion, like dizziness or vision problems. The assumption is straightforward - that damage to the corpus callosum could affect coordination between the two halves - but difficult to prove.
AMHERST, Mass. - A persistent question among urban ecology researchers has been the long-term impact of urbanization on bird species biodiversity. Specifically, they wonder whether the portions of cities with higher diversity are simply exhibiting an "extinction debt" - populations doomed to extinction but not yet disappeared - or if other factors such as range shifts or local environmental changes play a role in changes in diversity.
EAST LANSING, Mich. - When it comes to advancing social status, it's not what you know, it's who you know - for humans and spotted hyenas alike.
In a new study published in the current issue of Proceedings of the National Academy of Sciences, Michigan State University scientists show that hyenas that form strong coalitions can gain social status, which can have lasting benefits over many generations.
ITHACA, N.Y. - It's not whether you win or lose; it's how hard the robot is working.
A Cornell University-led team has found that when robots are beating humans in contests for cash prizes, people consider themselves less competent and expend slightly less effort - and they tend to dislike the robots.
A new study has found that frequent visits to the bathroom at night could cost the US economy $44.4 billion a year. According to researchers at the not-for-profit research organisation RAND Europe, waking up more than twice a night due to nocturia, a health condition that affects the lower urinary tract, can have a detrimental effect on a person's wellbeing and productivity at work, which in turn has an impact on a country's GDP.
Science is known for being objective and apolitical, but is it? Historically speaking, the voices of underrepresented groups have been missing from science, resulting in an often incomplete and fragmented perspective of the world. Without these voices, we are left with skewed ideas about race, ethnicity, class, sex, gender, and sexuality, how these concepts get made, and how they affect people's lives.
A new study in the Review of Economic Studies finds that U.S. counties with more historical immigration have higher incomes, less poverty, and lower unemployment today.
An important issue in current American political discourse is the effect that immigrants have on the communities in which they settle. While this topic has received significant attention, the focus has generally been on the short-term effects of immigrants. We know much less about the long-run consequences of immigration.
Modern coal-fired power stations produce more ultrafine dust particles than road traffic and can even modify and redistribute rainfall patterns, a new 15-year international study shows.
The study indicates filtration systems on modern coal-fired power stations are the biggest source of ultrafine particles and can have considerable impacts on climate in several ways.
In urban areas, road traffic has long been considered the main source of small particle emissions which have the potential to adversely affect health and the environment.
WEST LAFAYETTE, Ind. - A fascination with movie technology that showed robots perform self-repair through a liquid formula inspired a Purdue University professor to make his own discoveries - which are now helping to lead the way for advancements in self-powering devices such as consumer electronics and defense innovations.
When men and women contract a disease, it is very different when this is discovered by the healthcare system. On average, women are diagnosed later in life than men. This issue has been studied and analysed by researchers from the Novo Nordisk Foundation's Center for Protein Research, the Faculty of Health and Medical Sciences, UCPH, in a comprehensive study where data from the entire Danish population have been in use. The new research results have been published in the scientific journal Nature Communications.
