Québec produces more strawberries than any other Canadian province. Strawberries are delicate and difficult to keep fresh. In response to this challenge, Monique Lacroix, a professor at at the Institut national de la recherche scientifique (INRS), and her team have developed a packaging film that can keep strawberries fresh for up to 12 days.
Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is the earliest-yet-observed example of such a wind to date and is a telltale sign that huge black holes have a profound effect on the growth of galaxies from the very early history of the Universe.
Persisting symptoms thought to be complex interplay between effects of new injury and underlying conditions
Strict rest after a sports related concussion slows recovery and may prolong symptoms, says a consensus statement drawn up by a US expert panel on how best to treat and manage the condition, and published in the British Journal of Sports Medicine.
Most of these concussions get better within a month and can be effectively treated, it says.
The number of people dying from cardiovascular disease (CVD) in Asia is increasing rapidly, with over half of all CVD deaths globally in 2019 occurring in Asian countries, according to a state-of-the-art review paper published in the inaugural issue of JACC: Asia. The data demonstrates an urgent need to understand the burdens and epidemiological features of CVD in Asian countries to develop localized CVD prevention strategies to combat the epidemic.
There is increasing scrutiny around how science is communicated to the public, but what is the relationship between how scientists report their findings and how media reports it to the public? A study published in PLOS Biology by Marcia Triunfol at Humane Society International, in Washington, DC and Fabio Gouveia at Oswaldo Cruz Foundation in Rio de Janeiro, Brazil suggests that when authors of scientific papers omit the basic fact that a study was conducted in mice (and not in humans) from the article title, journalists reporting on the paper tend to do the same.
Killer whales have complex social structures including close "friendships", according to a new study that used drones to film the animals.
The findings show that killer whales spend more time interacting with certain individuals in their pod, and tend to favour those of the same sex and similar age.
The study, led by the University of Exeter and the Center for Whale Research (CWR), also found that the whales become less socially connected as they get older.
The omega-3 polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are found in oily fish. Researchers from the National Institute of Health Research (NIHR) Maudsley Biomedical Research Centre assessed the effects of high doses of EPA and DHA in lab-grown neurones and then in patients to help clarify how they reduce inflammation and depression.
The period preceding the emergence of behaviourally modern humans was characterised by dramatic climatic and environmental variability - it is these pressures, occurring over hundreds of thousands of years that shaped human evolution.
New research published today in the Cambridge Archaeological Journal proposes a new theory of human cognitive evolution entitled 'Complementary Cognition' which suggests that in adapting to dramatic environmental and climactic variabilities our ancestors evolved to specialise in different, but complementary, ways of thinking.
Federal agencies that regulate drug pricing and healthcare insurance are concerned that an industry practice of using rebates to lower drug costs for insurers has led to increases in list prices and out-of-pockets costs for patients.
In 1943, two scientists named Max Delbrück and Salvador Luria conducted an experiment to show that bacteria can mutate randomly, independent of external stimulus, such as an antibiotic that threatens a bacterial cells' survival. Today the Luria-Delbrück experiment is widely used in laboratories for a different purpose--scientists use this classic experiment to determine microbial mutation rates.
Instead of looking at the reasons child welfare caseworkers leave their jobs, Oregon State University researchers examined the common factors among workers who stay in the field, and what makes them feel most satisfied in their work.
In their recent study, researchers found that quality supervisory support and strong relationships with coworkers helped caseworkers feel appreciated and understood, while having adequate technology and equipment helped them manage their workload effectively
"So, no one told you life was going to be this way.
Your job's a joke, you're broke, you're love life's DOA.
It's like you're always stuck in second gear,
When it hasn't been your day, your week, your month, or even your year..."
When a fictional female journalist appears on screen, chances are she's about to sleep with one of her sources. It's a trope that infuriates actual women in news media -- and it can have real-life consequences, says University of Florida researcher Frank Waddell, Ph.D.
New research from Syracuse University Newhouse School of Public Communications reveals a relationship between political biases and attitudes about sexual assault.
Authored by assistant professor Rebecca Ortiz and PhD student Andrea Smith, the article "A social identity threat perspective on why partisans may engage in greater victim blaming and sexual assault myth acceptance in the #MeToo era," was published in the peer-reviewed journal Violence Against Women.
Teachers play a key role in supporting children's development in early childhood education classrooms such as Head Start. Research shows significant associations between teachers' depressive symptoms and their students' social and emotional development. However, little research has focused on the associations between teachers' depressive symptoms and academic outcomes of preschoolers from low-income families. Specifically, one important pathway that has not been examined is whether teacher depressive symptoms have implications for the quality of family-teacher relationships.
