More Canadian cities will experience damage from the emerald ash borer than previously thought. As a result of climate change and fewer days of extreme cold, the beetle may eat its way further north than originally estimated.
Kim Cuddington, a professor of biology at the University of Waterloo, led the team that produced a probability map for North America showing where the emerald ash borer is likely to kill trees.
Whether you learn to play a musical instrument or speak another language, you're training your brain to be more efficient, suggests a Baycrest study.
Researchers found that musicians and people who are bilingual utilized fewer brain resources when completing a working memory task, according to recently published findings in the journal, Annals of the New York Academy of Sciences.
Repeating seismic events--events that have the same frequency content and waveform shapes--may offer a glimpse at the movement of magma and volcanic gases underneath Turrialba and Poas, two well-known active volcanoes in Costa Rica.
At the 2018 SSA Annual Meeting, Rebecca Salvage of the Observatorio Vulcanologico y Sismologico de Costa Rica presented an analysis of these repeating signals from the volcanoes since July 2016.
Current global warming has far-reaching ecological consequences, also for the Earth's oceans. Many marine organisms are reacting by migrating towards the poles. Researchers at Geozentrum Nordbayern at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now discovered that marine animals have been migrating for millions of years when the temperature on Earth increases or decreases.
Marine animals follow changed temperature zones to the poles or equator
ROCKVILLE, MD - A trio of papers co-authored by four National Foundation for Cancer Research (NFCR) scientists has been published this week in highly-cited and respected journals. Each acknowledges NFCR support as having helped make the works possible.
Hamilton, ON (May 16, 2018) - A large international study led by a Hamilton researcher has found a patient-centric treatment that works for people with mild asthma.
People with mild asthma are often prescribed a daily treatment regimen, but up to 80 per cent do not follow the routine, using inhalers only when they have an asthma attack. Now the researchers have found an as-needed combined-drug inhaler is a viable treatment option.
PHILADELPHIA - Given the complex and rapidly evolving health care system in the United States, medical schools must focus their efforts on training more physician leaders to master the diverse skills needed to navigate emerging challenges in the field, urge leaders from the Perelman School of Medicine at the University of Pennsylvania in a new Perspective piece published today in the New England Journal of Medicine.
Before cell division, the long strings of the cell's DNA are wrapped tightly into the structures we know as chromosomes. This protects the cell's genetic material from physical and chemical damage.
The ends of chromosomes are called telomeres. These are specialized structures that have to be replicated with each cell division cycle. But the complete replication of telomeres up to the very ends of chromosomes also requires specialized mechanisms, and these are limited. Telomeres are also very sensitive to oxidative damage, which affects their ability to replicate.
About 22 million Americans are substance dependent (illicit drugs and alcohol), which interferes with routine life and requires treatment. Yet, only 2.5 million of these Americans participate in treatment services. The severe gap between the number of people who need treatment and the number of people who seek it poses a serious public health concern.
Bochum-based philosopher Dr Beate Krickel has used psychoanalysis to investigate why people are often not aware of their prejudices. In her accounts, she has been elaborating how prejudices can become unconscious. As researcher at the Institute of Philosophy II at Ruhr-Universität Bochum, she outlines her theory in the journal Philosophical Psychology from May 15, 2018.
Tolerant and yet full of bias
Data about marriages in Iran points to the declining number of formal (arranged) marriages in recent decades despite strong cultural and religious traditions favoring such marriages. Some social researchers have linked these declining trends to the economic constraints caused by a lack of well-paid jobs and a high cost of housing for the younger population.
A global expert on infrastructure says that China's plan to crisscross half of the Earth with massive transportation and energy projects is environmentally the riskiest venture ever undertaken.
"China has enormous ambitions," said Distinguished Professor William Laurance from James Cook University in Australia. "But with that comes enormous responsibilities."
Largest study to date shows that disrupted body clock rhythms are associated with increased susceptibility to depression, bipolar disorder, and adverse wellbeing
Disruption to normal daily circadian rhythms is associated with a greater susceptibility to mood disorders such as severe depression and bipolar disorder over the life course, according to the largest observational study of its kind involving over 91,000 people, published in The Lancet Psychiatry.
The first European-wide genomic survey of gonorrhoea has mapped antibiotic resistance in this sexually transmitted disease throughout the continent. Researchers at The Centre for Genomic Pathogen Surveillance (CGPS), the Wellcome Sanger Institute, European Centre for Disease Control, and their collaborators also showed that using DNA sequencing data they could accurately determine antibiotic resistance and identify incorrect laboratory test results. This genomic approach could one day help doctors prescribe the most effective antibiotics for each region.
Chimpanzees (Pan troglodytes) appear to keep tidier sleeping arrangements than humans do. That's one finding of a recent study that evaluated the microbes and arthropods found in the treetop beds that chimpanzees make each night.
