Dopamine increases willingness to wait for rewards

Researchers found that L-DOPA increased participants' willingness to wait for larger delayed rewards by 20%, decreasing impulsivity. The study also suggests that dopamine's effect on waiting may not stem from changes in basic decision processes, but rather from future reward valuation.

Opt-out organ donation policies are reducing the amount of living donors, which is affecting the overall supply of organs, according to a new study

A new study found that opt-out organ donation policies reduce living donors by 29% but don't increase the total supply of organs. The transition to an opt-out system alters people's perception of organ availability, leading them to believe it solves the shortage, resulting in fewer altruistic donations.

Study reveals clinical frailty scale as a quick predictor of patient risk after heart failure administration

A study found that the Clinical Frailty Scale (CFS) is a quick predictor of patient risk after heart failure administration. The researchers used anonymized patient information from Japan and found that CFS scores were strongly correlated with physical and cognitive impairment, as well as increased mortality risk.

Johns Hopkins-led study finds drugs approved for treating pain also reduce bone cancer growth

A Johns Hopkins-led study has found that two analgesic drugs, bupivacaine and rimegepant, can slow the growth of osteosarcoma tumors by inhibiting nerve signaling. The researchers tested these medications in mice with osteosarcoma-like tumors and observed a significant reduction in tumor growth and spread.

Cul-de-sac effect: Why Mediterranean regions are becoming more prone to extreme floods in a changing climate

New research reveals that prolonged accumulation of rain over several days, fueled by mountains blocking moisture from the Adriatic Sea, causes extremely rare floods. The study identifies a 'cul-de-sac' effect, where stationary cyclones channel humid air toward vulnerable regions, increasing flood risk.

Missing nutrient in breast milk may explain health challenges in children of women with HIV
