After a long day of work and carefully watching what you eat, you might expect your self-control to slip a little by kicking back and cracking open a bag of potato chips.

But according to new U of T Scarborough research, self-control may be less limited than we often believe. In fact, there may be no noticeable dip in our motivation and ability to do something as long as we switch up tasks throughout the day.

Based on data from 10 long-term forest monitoring plots, including seven from the Smithsonian's ForestGEO network, a team led by Jacob Usinowicz during his doctoral dissertation at the University of Wisconsin-Madison, provides the first evidence that the 'storage effect' enables tree species to coexist and is stronger in the tropics. The team's results, published in the Sept. 20 edition of the journal Nature, address a question that has long challenged biologists: Why are there so many more species in the tropics?

The mental and physical stress on individuals caring for elderly loved ones with chronic and terminal disease is well-documented and known as caregiver burden. It is linked to depression, anxiety and poor quality of life. There are ways to prevent and treat it. But what about caregivers of pets with chronic and terminal diseases? Do they carry the same level of stress and burden?

Until recently, very little scientific research has been published on what these caregivers go through and how they handle the stress.

The author of a new study showing slow but consistent progress in the experiences of LGBTQ students on college campuses over the past 70 years is concerned that for the first time since 1944, that trend may be reversing.

In the United States, therapeutic horseback riding offers equine-assisted therapy to diverse populations, including children and adults who have anxiety disorders. Veterans diagnosed with post-traumatic stress disorder often are prescribed this type of therapy in order to cope with anxiety, but little is known about how these programs affect the stress levels in horses.

The PhD degree was established in Berlin 200 years ago and has spread across the world. Today there is a global tendency to follow the programs currently used either in the United States or in Continental Europe. A new study in FEBS Open Bio examines how US and European PhD programs are both similar and different.

The analysis, based on what is called the ORPHEUS self-assessment questionnaire, concerned research environment, outcomes, admission criteria, content of programs, mentoring, PhD theses, assessment of theses, and PhD school structure.

ANN ARBOR, Mich. -- If your child had an asthma attack during the school day, would school personnel know how to respond?

Which staff at your child's school would recognize and assist an elementary student with prolonged sadness over his parents' divorce? Or a teen who was struggling with anxiety about academic pressure?

AUSTIN, Texas -- Every couple has conflict, and new research finds that having good friends and family members to turn to alleviates the stress of everyday conflict between partners. In fact, according to the study led by The University of Texas at Austin's Lisa Neff, social networks may help provide protection against health problems brought about by ordinary tension between spouses.

Only seven states in the United States have mandatory paid sick leave laws; yet, 15 states have passed preemptive legislation prohibiting localities from passing sick leave. Despite this resistance, paid sick leave is starting to gain momentum as a social justice issue with important implications for health and wellness. But what are the implications for the mental well-being of Americans without paid sick leave? Little was known about their relationship until now.
