A recent study finds that older adults feel younger when they feel that they have more control over their daily lives, regardless of stress or health concerns. However, stress and health – not a sense of control – play a significant role in how old younger adults feel. “We recently found that there are things …
National Institutes of Health director Francis Collins and top science and ethics experts in the U.S. and 6 other countries today called for an international 5-year moratorium on editing human germlines, or the type of genes that are heritable. Why it matters: Spurred by the recent discovery of twin babies born after being edited as …
The environment can have a major effect on the human cardiovascular system. It has long been assumed that severe spikes in temperature increase the risk of heart attack. “In the case of very high and very low temperatures in particular, this has been clearly demonstrated. In this latest study, we wanted to see to what …
The concept of equilibrium, one of the most central ideas in economics and one of the core assumptions in the vast majority of economic models, may have serious problems, concludes a study from the Institute for New Economic Thinking at the Oxford Martin School. The concept of equilibrium is the basis of many economic models, …
It may never be too late for adults to become physically active and enjoy some health benefits. This observational study looked at how patterns of leisure-time physical activity from adolescence (15 to 18) to later adulthood (40-61) were associated with risk of dying using data for 315,000 U.S. adults. The results suggest maintaining physical activity …
It seems that napping may do more than just reboot our energy level and improve our mood. New research being presented at the American College of Cardiology’s 68th Annual Scientific Session found that people who took advantage of a midday snooze were more likely to have a noticeable drop in blood pressure compared with those …
A new CAMH study shows for the first time that people experiencing clinical depression have higher levels of a brain protein called MAO-B. The finding – published online today in JAMA Psychiatry – opens the door to a new area of exploration for developing depression treatments. Depression affects an estimated 15 per cent of people …
An international team has developed newly refined techniques for obtaining past climate data from mollusc shells. Mollusc shells are abundant in archaeological sites spanning the last 160,000 years. Using laser imaging, researchers have now found new ways of reconstructing how climate changed during a mollusc’s lifetime, down to the seasonal level. Their technique makes it …
Earlier today, the FDA approved esketamine (brand name Spravato), a relative of the dissociative psychedelic/anaesthetic ketamine (Special K), as a treatment for depression. Spravato comes in nasal spray form meant to be administered weekly or every other week depending on the severity of the patient’s depression. “There has been a longstanding need for additional effective …
Incorporating the arts–rapping, dancing, drawing–into science lessons can help low-achieving students retain more knowledge and possibly help students of all ability levels be more creative in their learning, finds a new study by Johns Hopkins University. The findings were published on Feb. 7 in Trends in Neuroscience and Education and support broader arts integration in …
