A little bit of sensitivity training can help people form better first impressions of those with facial paralysis, reducing prejudices against people with a visible but often unrecognizable disability, new research from Oregon State University indicates.

There is a natural tendency to base first impressions on a person's face, but those impressions can be inaccurate and often negative when the person has facial paralysis, said Kathleen Bogart, an assistant professor of psychology in the College of Liberal Arts at Oregon State University.

Disparities in cancer screening, incidence, treatment, and survival are worsening globally. In a new study on colorectal cancer, researchers found that the mortality-to-incidence ratio (MIR) can help identify whether a country has a higher mortality than might be expected based on cancer incidence.

Countries with lower-than-expected MIRs have strong national health systems characterized by formal colorectal cancer screening programs. Conversely, countries with higher-than-expected MIRs are more likely to lack such screening programs.

The majority of young women and men today would prefer an egalitarian relationship in which work and family responsibilities are shared equally between partners if that possibility were available to them, according to a new study from the University of Texas at Austin and the University of California-Santa Barbara.

The paper in the American Sociological Review was co-authored by David S. Pedulla, an assistant professor of sociology at the University of Texas at Austin, and Sarah Thébaud, an assistant professor of sociology at the University of California-Santa Barbara.

Commonly accepted domestication hypotheses suggest: "Dogs have become tolerant and attentive as a result of humans actively selecting for these skills during the domestication process in order to make dogs cooperative partners."

People are more successful in taking up healthy habits if their partner makes positive changes too, according to research* published in JAMA Internal Medicine today (Monday).

Scientists at UCL funded by Cancer Research UK, the British Heart Foundation, and the National Institute on Aging looked at how likely people were to quit smoking, start being active, or lose weight in relation to what their partner did.**

They found that people were more successful in swapping bad habits for good ones if their partner made a change as well.
