Adaptable decision making in the brain

A team of researchers has discovered that a part of the brain, known as the frontopolar cortex, plays a critical role in making short-term predictions about what will happen next. This region helps individuals make decisions in rapidly changing environments by learning from past experiences and anticipating future events.

The role of dopamine in sleep regulation

Researchers discovered that dopamine inhibits melatonin production by forming 'heteromers' with norepinephrine receptors, regulating the body's circadian rhythm. This discovery could lead to new treatments for circadian rhythm disturbances and sleep disorders affecting 40% of the world's population.

'Color blind' policies could make diversity harder to achieve

A recent study published in Current Directions in Psychological Science found that color-blind policies can backfire, leading to increased racial bias and tension. The authors propose a multicultural approach as an alternative, which has been shown to improve understanding and spotting of discrimination., Minority applicants perceive d...

Long-term cancer survivors struggle to keep regular work hours

A study by Steffen Torp and colleagues found that long-term cancer survivors take significantly more sick leave than their non-cancer counterparts. Socio-demographic factors, such as education level and family status, were key predictors of sick leave, rather than the type or severity of cancer.

NIH study finds HIV-positive young men at risk of low bone mass

A recent NIH study found that HIV-positive young men are more likely to experience low bone mass than their peers. Regular monitoring, exercise, and sufficient vitamin D intake can help prevent future fracture risk. The study's findings highlight the importance of addressing bone health in this vulnerable population.

Blogging relieves stress on new mothers

Research found that blogging positively impacts new mothers' well-being by increasing feelings of social support, marital satisfaction, and reducing parenting stress. Blogging provides an outlet for stay-at-home moms to connect with family and friends, showcasing their hobbies and accomplishments.

Study: Willingness to be screened for dementia varies by age but not by sex, race or income

A recent study found that almost 90% of older adults aged 65-96 were willing to undergo dementia screening, with refusal rates higher among those between 70-79 years old. The study's results suggest that age is the primary factor affecting willingness, with no significant impact from sex, race, or income level.
