Their results suggest that adherence to the MD could reduce the high risk of RA among ever‐smoking women.

Levodopa may improve vision in patients with macular degeneration - داروی پارکینسون ممکن است برای بینایی سالمند مفید باشد

The widely used and well-tolerated drug commonly used to treat Parkinson’s disease may help significantly reduce the need for more costly, more invasive treatments, report investigators in The American Journal of Medicine.

Investigators have determined that treating patients with an advanced form of age-related macular degeneration (AMD) with levodopa, a safe and readily available drug commonly used to treat Parkinson’s disease, stabilized and improved their vision. It reduced the number of treatments necessary to maintain vision, and as such, will potentially reduce the burden of treating the disease, financially and otherwise.

A pain reliever that alters perceptions of risk - مسکنی که خطرپذیری افراد را افزایش می دهد

People who took acetaminophen rated activities like “bungee jumping off a tall bridge” and “speaking your mind about an unpopular issue in a meeting at work” as less risky than people who took a placebo, researchers found.

Use of the drug also led people to take more risks in an experiment where they could earn rewards by inflating a virtual balloon on a computer: Sometimes they went too far and the balloon popped.

The study was published online in the journal Social Cognitive and Affective Neuroscience.

Unconscious Learning Underlies Belief in God - انسان ها به صورت ناخودآگاه خداباوری را یاد می گیرند

Individuals who can unconsciously predict complex patterns, an ability called implicit pattern learning, are likely to hold stronger beliefs that there is a god who creates patterns of events in the universe.

Their research, reported in the journal Nature Communications, is the first to use implicit pattern learning to investigate religious belief. The study spanned two very different cultural and religious groups, one in the U.S. and one in Afghanistan.

Children Use Both Brain Hemispheres to Understand Language, Unlike Adults - کودکان از هر دو نیمکره مغزی برای درک زبان استفاده می کنند

Infants and young children have brains with a superpower, of sorts, say Georgetown University Medical Center neuroscientists. Whereas adults process most discrete neural tasks in specific areas in one or the other of their brain’s two hemispheres, youngsters use both the right and left hemispheres to do the same task. The finding suggests a possible reason why children appear to recover from neural injury much easier than adults.

Exposure to light-emitting media devices at night linked with poor sperm quality - نور وسایل الکترونیکی در شب می تواند باعث کاهش کیفیت اسپرم ها شود

Men might want to think twice before reaching for their smartphone at night. A new study found correlations between electronic media use at night and poor sperm quality.

Preliminary results show that greater self-reported exposure to light-emitting media devices in the evening and after bedtime is associated with a decline in sperm quality. Sperm concentration, motility and progressive motility — the ability of sperm to “swim” properly — were all lower, and the percentage of immotile sperm that are unable to swim was higher, in men who reported more smartphone and tablet usage at night.

sleep restriction amplifies anger - محرومیت از خواب باعث تشدید خشونت میشود

 Feeling angry these days? New research suggests that a good night of sleep may be just what you need.

This program of research comprised an analysis of diaries and lab experiments. The researchers analyzed daily diary entries from 202 college students, who tracked their sleep, daily stressors, and anger over one month. Preliminary results show that individuals reported experiencing more anger on days following less sleep than usual for them.

The research team also conducted a lab experiment involving 147 community residents. Participants were randomly assigned either to maintain their regular sleep schedule or to restrict their sleep at home by about five hours across two nights. Following this manipulation, anger was assessed during exposure to irritating noise.
