In August, the Ontario Superior Court of Justice dismissed a malpractice lawsuit filed against two physicians who refused to provide cardiopulmonary resuscitation (CPR) to an 88-year-old man with multiple comorbidities and multiorgan failure. This ruling may have important implications for physicians in Ontario and elsewhere, according to a commentary published in this week's CMAJ (Canadian Medical Association Journal).
What The Study Did: Ethnic and racial differences between educational attainment by parents and outcomes among young people related to behavior, academics and health were explored in this observational study. The study included 10,619 adolescents ages 12 to 17 who participated in a nationally representative survey.

US President Donald Trump is busy dismantling climate policies in the largest economy in the world. Europeans, while recognizing their climate obligations, still have among the highest carbon footprints on the planet.
So what's a concerned global citizen to do? Can people's actions -- outside of large-scale government interventions --make a difference?
A new study suggests the answer is yes.
Researchers at the Federal University of Rio de Janeiro (UFRJ), in Brazil, have identified that the interaction between prion proteins and DNA may be behind the formation of protein amyloid aggregates and of the emergence of neurodegenerative diseases such as Creutzfeldt-Jakob disease and other spongiform encephalopathies. The study appears today in the FASEB Journal.
A novel mental health program improves teenagers' ability to recognise and support friends who might be at risk of suicide, according to new research.
University of Melbourne researchers have evaluated the impact of teen Mental Health First Aid (tMHFA) - a universal mental health literacy program for high school students in Years 10-12 - as an intervention to improve peer support towards adolescents at risk of suicide.
The brain cortex, the outside layer of our brain often referred to as grey matter, is one of the most complex structures found in living organisms. It gives us the advanced cognitive abilities that distinguish us from other animals.
Neuroscientist Prof. Pierre Vanderhaeghen (VIB-KU Leuven, Université libre de Bruxelles) explains what makes the human brain so unique: "One remarkable feature of human neurons is their unusually long development. Neural circuits take years to reach full maturity in humans, but only a few weeks in mice or some months in monkeys."
Princeton University-led researchers have extracted 2 million-year-old ice cores from Antarctica that provide the first direct observations of Earth's climate at a time when the furred early ancestors of modern humans still roamed.
After a decade-long search, an international team of researchers including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) have for the first time detected a gamma-ray burst in very-high-energy gamma light. This discovery was made in July 2018 by the H.E.S.S. collaboration using the huge 28-m telescope of the H.E.S.S. array in Namibia. Surprisingly, this Gamma-ray burst, an extremely energetic flash following a cosmological cataclysm, was found to emit very-high-energy gamma-rays long after the initial explosion.
UPTON, NY--Scientists have developed a new approach for making metal-metal composites and porous metals with a 3-D interconnected "bicontinuous" structure in thin films at size scales ranging from tens of nanometers to microns. Metallic materials with this sponge-like morphology--characterized by two coexisting phases that form interpenetrating networks continuing over space--could be useful in catalysis, energy generation and storage, and biomedical sensing.
Hartford, Conn. -- Seventy percent of teens surveyed report engaging with food and beverage brands on social media and 35 percent engaged with at least five brands, according to a new study from the UConn Rudd Center for Food Policy & Obesity published in the journal Appetite. The study, funded by the Robert Wood Johnson Foundation, found that 93 percent of the brands that teens reported engaging with on social media were fast food, unhealthy snack foods, candy, and sugary drinks, which are primarily the brands that target them with traditional forms of advertising.
If you've ever woken up in the middle of the night to go to the bathroom and stumbled around in the dark, banging into walls or dressers in a room you've walked through countless times, you've experienced the effects of inadequately calibrated neurons.
In many animals, humans included, an accurate sense of direction is generated with the help of brain cells known as head direction neurons, which do so by incorporating two main streams of information--visual landmarks and positional estimates based on self-movement.
An international, multidisciplinary research team from more than 50 institutions, led by geneticist and psychiatrist Gholson Lyon, MD, PhD, of the New York State Office for People With Developmental Disabilities' (OPWDD) Institute for Basic Research in Developmental Disabilities (IBR), today announced publication of findings from its study of the rare disease TAF1 syndrome.
Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates.
Hand-dug trenches around Leigh Lake in Grand Teton National Park in Wyoming reveal evidence for a previously unknown surface-faulting earthquake in along the Teton Fault--one occurring about 10,000 years ago.
A standout essay, high grade point average and stellar standardized test scores are sometimes not enough for college admissions.
The ongoing college admission scandal underscores how influential a standardized test score has become. A test administrator is now cooperating with the investigation into other parents who paid to have their children's test scores fixed.
