Earwigs have wings that fold in ways that should be mathematically impossible, according to origami theory. The common pests have a rubbery polymer that lets them fold up their wings into tiny packages.
Medical expansion has improved health – with one exception: Increased spending on health care and increases in specialized care were both associated with longer life expectancy and less mortality, but growing drug industry linked to worse health in 30 countries.
A single intravenous infusion of ketamine led to a rapid decrease in suicidal ideations. Within a day, about 55% of individuals who received ketamine no longer had suicidal ideations compared to 20% who received placebo. This reduction in suicidal ideations lasted for at least 7 days.
Being in the hospital leads to a 20% drop in future earnings on average for adults 50-59, even if they have medical insurance
Toddlers learn nothing from YouTube videos. New study finds that two-year-olds enjoy the commercials more than the videos (and seem engaged with musical clips) but do not learn anything from YouTube.
Squids have a tougher time hunting these days, and it's because of climate change. High carbon dioxide levels affect how they go after prey, researchers found. It "could have far?reaching consequences in marine ecosystems due to the ecological importance of cephalopods in the marine food web."
Breast Implants Could Cause An Unusual Cancer
EPFL scientists have identified a mechanism that confers resistance against a common therapy for lymphoma. They propose an alternative treatment that targets lymphoma signaling at its root, and show that it can be effective in a broader group of patients. The study is published in the journal Blood.
Living abroad can clarify your sense of self. They found living abroad increases "self-concept clarity," the extent to which individuals' beliefs about themselves are clearly and confidently defined and consistent and stable over time.
Finding food is a necessary survival skill, but so is avoiding pain. Research using mice showed that being hungry activates a neural pathway that inhibits the perception of and response to chronic pain. The findings offer up new targets for treating pain.

The Effort Paradox: Prominent models indicate that effort is costly, and that we avoid it. A new series of studies show that this is only half the story. Humans and non-human animals alike tend to associate effort with reward and will sometimes select activities because they require effort

The first known interstellar asteroid, 'Oumuamua (Hawaiian for "scout"), was likely ejected from a binary star system. By modeling how efficient various systems are at ejecting comets and asteroids, researchers showed 36% of binaries (the most common type of star system) eject primarily asteroids.

Older adults may be more prone to false memories - Researchers have discovered that as people age, they may be more likely to rely on a type of memory, called schematic memory, that helps them remember the gist of an event, but not necessarily the details.
Wounds in the fetus can heal without scarring, a fact that has prompted scientists to design new biomaterials based on the properties of fetal skin. Now, a new type of nanofiber has been shown to heal wounds in mice faster and with less scarring than untreated wounds.

21 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.
54 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.

31 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.
