Students given extra points if they met "The 8-hour Challenge" -- averaging eight hours of sleep for five nights during final exams week -- did better than those who snubbed (or flubbed) the incentive, according to Baylor University research.

A team of scientists from Arizona State University's School of Molecular Sciences and Germany have published in Science Advances online today an explanation of how a particular phase-change memory (PCM) material can work one thousand times faster than current flash computer memory, while being significantly more durable with respect to the number of daily read-writes.

The scene: a bitter divorce, and a custody battle over the couple's 7-year-old son. Awarded full custody, the mother - perhaps seeking revenge? - sets out to destroy the son's relationship with his father. The mother tells the son lies about the father's behavior, plants seeds of doubt about his fitness as a parent, and sabotages the father's efforts to see his son. The son begins to believe the lies; as he grows up, his relationship with his father becomes strained.

The more often adolescents say they have seen adverts for e-cigarettes, the more often they use both e-cigarettes and smoke tobacco cigarettes, according to a study published in ERJ Open Research [1].

The study took place in Germany, where regulations around tobacco and e-cigarettes advertising are more permissive than in other parts of Europe. Elsewhere there are firm bans on advertising tobacco but certain types of adverts and promotions for e-cigarettes are permitted.

ANN ARBOR--An extremely messy personal space seems to lead people to believe the owner of that space is more neurotic and less agreeable, say University of Michigan researchers.

Psychologists from U-M's Flint and Ann Arbor campuses explored the degree of messiness in one's workspace and how it affects perceptions of the owner's personality.

In three experiments, about 160 participants were randomly assigned to sit in a researcher's office that was clean and uncluttered, or in another office that was either "somewhat" or "very" messy.

Stressful events in the evening release less of the body's stress hormones than those that happen in the morning, suggesting possible vulnerability to stress in the evening.

The body's central system reacts less strongly to acute psychological stress in the evening than it does in the morning, according to research conducted at Japan's Hokkaido University.

Cognitive behavioural therapy (CBT) delivered by respiratory nurses is cost-effective and reduces anxiety symptoms in chronic obstructive pulmonary disease (COPD) patients, according to research published in ERJ Open Research [1].

A woman lies in her hospital bed. Her heart rate is elevated, she has a slight fever and an elevated white blood cell count.

Could this be the beginnings of sepsis, a life-threatening reaction to an infection? Or could these simply be signs of a normal pregnancy?

Maternal sepsis, which occurs during pregnancy or postpartum, is a rare but possibly preventable complication that accounts for 12.7 percent of pregnancy-related deaths in the United States each year.

WASHINGTON -- A comprehensive analysis examining the relationship between vaping and smoking among youth and young adults finds that cigarette smoking dramatically decreased between 2013 and 2017 just as e-cigarette use became more popular.

The study, published in the journal Tobacco Control, looked at five different U.S. population-level surveys that covered the four year time frame -- the time during which vaping became increasingly popular.

ANN ARBOR, Mich. - A significant proportion of suicidal teens treated in a psychiatric emergency department said that watching the Netflix series "13 Reasons Why" had increased their suicide risk, a University of Michigan study finds.

The hit drama, widely popular among teens, has generated controversy for its depiction of suicide. Its story centers around a 17-year-old student, who, before her death, recorded cassettes that detail 13 reasons why she took her own life.
