TORONTO, June 21, 2018--A preference for male children persists among second-generation mothers of South Asian descent, according to new study that found a skewed ratio of male-to-female babies born to these women in Ontario.
The findings, published today in the Journal of Epidemiology and Community Health, came from the same group of researchers who reported in 2016 that more male babies than expected were being born to Indian-born women living in Canada.
CHAPEL HILL, NC - When cells grow and divide to ensure a biological function - such as a properly working organ - DNA must be unwound from its typical tightly packed form and copied into RNA to create proteins. When this process goes awry - if too little or too much RNA is produced - then the result could be diseases such as cancers.
New Rochelle, NY, June 20, 2018--Tissue-engineered articular cartilage (AC) for repairing cartilage damaged by trauma or disease can be made to more closely mimic natural AC if mechanical stimulation of particular magnitude and duration is applied during the development process.
The UK's first energy-positive classroom, designed with research expertise from Swansea University, generated more than one and a half times the energy it consumed, according to data from its first year of operation, the team has revealed.
The findings were announced as the researchers launched the next phase of their research, gathering data and evidence on an office building, constructed using similar methods.
DURHAM, N.C. - Exposure to fracking chemicals and wastewater promotes fat cell development, or adipogenesis, in living cells in a laboratory, according to a new Duke University-led study.
A new study from the University of Waterloo has found that Ontario could save millions by implementing simple measures to help prevent vehicle accidents involving wildlife.
The Waterloo study focused on Ontario. It concluded that many of the thousands of wildlife-vehicle collisions -- some fatal -- occurring each year could be prevented if authorities implemented a few, cost-effective strategies to minimize the occurrences.
As a chameleon shifts its color from turquoise to pink to orange to green, nature's design principles are at play. Complex nano-mechanics are quietly and effortlessly working to camouflage the lizard's skin to match its environment.
Inspired by nature, a Northwestern University team has developed a novel nanolaser that changes colors using the same mechanism as chameleons. The work could open the door for advances in flexible optical displays in smartphones and televisions, wearable photonic devices and ultra-sensitive sensors that measure strain.
According to the United Nations, 2.1 billion people lack access to safely managed drinking water services, the majority of whom live in developing nations.
The percentage of multiracial congregations in the United States has nearly doubled, with about one in five American congregants attending a place of worship that is racially mixed, according to a Baylor University study.
While Catholic churches remain more likely to be multiracial -- about one in four -- a growing number of Protestant churches are multiracial, the study found. The percentage of Protestant churches that are multiracial tripled, from 4 percent in 1998 to 12 percent in 2012, the most recent year for which data are available.
Researchers funded by the National Institutes of Health have shown that a therapy-based treatment for disruptive behavioral disorders can be adapted and used as an effective treatment option for early childhood depression. Children as young as 3-years-old can be diagnosed with clinical depression, and although preschool-aged children are sometimes prescribed antidepressants, a psychotherapeutic intervention is greatly needed. The study, funded by the National Institute of Mental Health (NIMH), part of NIH, appears online June 20 in the American Journal of Psychiatry.
Researchers more than doubled the ability of a material to convert heat into electricity, which could help reduce the amount of wasted heat, and thus wasted fossil fuel, in daily activities and industries.
Researchers from Hokkaido University and their colleagues in Japan and Taiwan have improved the ability to transform wasted heat into usable electricity by significantly narrowing the space through which spread electrons move, according to a new study published in the journal Nature Communications.
New York, NY--June 19, 2018--A major challenge in current climate prediction models is how to accurately represent clouds and their atmospheric heating and moistening. This challenge is behind the wide spread in climate prediction. Yet accurate predictions of global warming in response to increased greenhouse gas concentrations are essential for policy-makers (e.g. the Paris climate agreement).
Researchers at MIT, who last year designed a tiny computer chip tailored to help honeybee-sized drones navigate, have now shrunk their chip design even further, in both size and power consumption.
The team, co-led by Vivienne Sze, associate professor in MIT's Department of Electrical Engineering and Computer Science (EECS), and Sertac Karaman, the Class of 1948 Career Development Associate Professor of Aeronautics and Astronautics, built a fully customized chip from the ground up, with a focus on reducing power consumption and size while also increasing processing speed.
Keyhole surgery for heart valve repair may trump robotic surgery, because it is associated with lower rates of subsequent heart flutter and blood transfusions, and a shorter hospital stay, reveals research looking at the pros and cons of different surgical approaches, published online in the journal Heart.
But as keyhole, robotic, and conventional surgery are all very safe and effective, the choice of which to perform should be governed by patient preference and the experience of the operating surgeon, suggest the researchers.
A quarter of the seafood tested from Metro Vancouver grocery stores, restaurants and sushi bars is not what you think it is.
A new UBC study used DNA barcoding to determine that 70 of 281 seafood samples collected in Metro Vancouver between September 2017 and February 2018 were mislabelled.
Researchers from UBC's Lu Food Safety & Health Engineering Lab conducted the study in partnership with independent charity Oceana Canada and the Hanner Lab at the University of Guelph.
