The United States spent approximately twice as much as other high-income countries on medical care, yet utilization rates were largely similar to those in other nations. Prices of labor and goods, including pharmaceuticals and devices, and administrative costs appeared to be main drivers - JAMA
A new study finds that listening to motivational music during sport activities increases risk-taking behavior but does not improve overall performance.
Teenagers are more likely to plead guilty to crimes they did not commit because they are less able to make mature decisions, new research shows. Other research has found adolescents are less able to perceive risk and resist the influence of peers because of developmental immaturity.
Astronomers nearly doubled the previous record for a distance measurement within our galaxy, which paves the way for a full galactic map. By using natural Masars, the team determined the distance to a star-forming region on the far side of the Milky Way, some 66,000 light-years away.
Asteroids and comets provide Mars with 30% of its organic material. Lead author: “Near other stars, there are also exo-asteroids and exo-comets that can shower the surfaces of exoplanets with carbon. If, on top of that, there is water, then you have the required ingredients for life."

Landmark Report Concludes Abortion In U.S. Is Safe -- "The report also says nurse practitioners and physician assistants can perform abortions just as safely as physicians. Also, abortions have no long-term consequences on women's physical and mental health"
Adults’ Political Leanings Linked With Early Personality Traits. Studies indicate that children who showed higher levels of conduct problems — that is, aggression, fighting, stealing from peers — were more likely to be economically left leaning and distrustful of the political system as adults
Changes in the sense of taste and smell are a common side-effect experienced by patients being treated for cancer. Changes in these senses can affect food preferences and food intake of the patient. Therefore, eating healthy and tasteful might become a problem for cancer patients.

A study has found that in order to build the Great Pyramids Egyptians created points-of-reference using the sun during the autumn equinox - a day halfway between the summer and winter solstices when day and night are of equal length.
Pain's Origins May Be Significantly Different in Males and Females - "New research from The University of Texas at Dallas supports the growing consensus that pain begins differently for men and women at the cellular level."

Solenodon: This bizarre venomous mammal that survived the asteroid that killed the dinosaurs has had its genome sequenced for the first time. Scientists found the genus most likely diverged from other living mammals around 73.6 million years ago, before the devastating asteroid impact.

American Psychopaths And Dutch Psychopaths Display Different Personality Traits. Whereas “callousness” and “lack of empathy” seem to be the defining characteristics of your typical American psychopath, Dutch psychopaths are better recognized for their “irresponsibility” and “parasitic lifestyle”.

Teens who are old for their grade appear to feel more confident about their academic abilities and are more likely to enroll in college than their younger peers, according to research published by the American Psychological Association.
Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications. The system, created by a team from Imperial College London, encapsulates biological cells within an artificial cell.

A Systematic Review Shows How to Maintain Sexual Desire in a Relationship. Studies show that partners must both feel attractive and be attracted to their significant others. This encompasses emotional and physical facets. Emotionally, confidence and attentiveness factor most into attraction.
Space Radiation is Increasingly More Hazardous - Radiation dose rates over last four years exceeded trends from previous solar cycles by at least 30%, showing that the radiation environment is getting far more intense, with implications for future missions to the moon, Mars, asteroids and beyond.
A new systematic review, now published in the Harvard Review of Psychiatry, found that people living in high-altitude areas of the United States, such as intermountain states, have higher-than-average rates of suicide and depression.

During the hours of sleep the memory performs a cleaning shift: a study reveals that when mice sleep, the neural connections that collect important information are strengthened and those created from irrelevant data are weakened until they get lost.
Cell therapy for Alzheimer's disease - Inhibitory interneurons are particularly important for managing brain rhythms. Researchers have uncovered the therapeutic benefits of genetically improving these interneurons and transplanting them into the brain of a mouse model of Alzheimer's disease.

22 mvea Journal reference: Durable and Washable Antibacterial Copper Nanoparticles Bridged by Surface Grafting Polymer Brushes on Cotton and Polymeric Materials, Xuqing Liu. Journal of Nanomaterials, vol. 2018, Article ID 6546193, 2018. doi:10.1155/2018/6546193. Link: Abstract > To increase the durability of antibacterial coating on cotton and polymeric substrates, surface initiated grafting polymer brushes are introduced onto the substrates surface to bridge copper nanoparticles coatings and substrate. The morphologies of the composites consisting of the copper nanoparticles and polymer brushes were characterized with scanning electron microscopy (SEM). It was found that copper nanoparticles were uniformly and firmly distributed on the surfaces of the substrates by the polymer brushes; meanwhile, the reinforced concrete-like structures were formed in the composite materials. The substrates coated by the copper nanoparticles showed the efficient antibacterial activity against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) even after washing by 30 cycles. The copper nanoparticles were tethered on the substrates by the strong chemical bonds, which led to the excellent washable fitness and durability. The change of the phase structure of the copper was analyzed to investigate the release mechanism of copper ions.
55 LabTech41 Infection outbreaks at hospitals could ALSO be reduced by doctors and nurses actually FOLLOWING infection control protocols. Yes, virtually all will follow the ones for special cases like TB aerosols and such, but go to any hospital and you'll find doctors and nurses walking around in the same white coats they've dragged through every room in the hospital with. You'll see them walking in the halls, brushing it against patients and visitors alike, they'll even bring them into the cafeteria. There's a significant portion of these people that won't do or follow a rule unless it's explicitly stated and meant to protect them and their paycheck. Copper nanoparticles are all well and good, but if the basics aren't adhered to, fancy coats won't do shit.

29 idioteques I am generally perplexed when I see someone wearing their scrubs in public... like boarding a plane... or the Subway. I assume they wear those things to prevent introducing potentially communicable things outside of the medical facility? (or maybe the people I see are pedicure technicians?)
10 chellis88 There are so many ways to reduce the spread of infection in hospitals. Most of them would involve less direct contact. The best idea I've seen of late was the far UV-C lights. Or just going back to solariums.
