People with more wealth tend to report being happier with life, according to a new psychological study of more than 4,000 millionaires. The study also found evidence that millionaires who earned their wealth were happier than those who inherited it.
Infection outbreaks at hospitals could be reduced by copper-coated uniforms - Doctors, nurses and healthcare professionals could soon be wearing uniforms brushed with tiny copper nanoparticles to reduce the spread of bacterial infections and viruses at hospitals.
New blood test can detect autism in children. Researchers at the University of Warwick discover link between autism and damage to proteins in blood plasma.
A new study finds that farming crops with crushed rocks could help to improve global food security and reduce the amount of CO2 entering the atmosphere. The fast-reacting silicate rocks capture CO2 and give increased protection from pests and diseases while restoring soil structure and fertility.
Whistleblowers often suffer from severe psychological problems. About 80% report very negative effects on work and wages, and almost 50% very negative effects on family life. About 45% suffer from clinical levels of mental health problems such as anxiety and/or depressive symptoms.
Archeologists find mutilated 8,000-year-old skulls, some possibly mounted on stakes. While plenty of cultures throughout the world have placed skulls on stakes, either as trophies or a “back off” signal to enemies, this would be the earliest known example found in Europe.

Teens work very hard to create a favorable online image through careful selection of which photos, activities and links to post on Facebook and Instagram, according to a recent study. Content that makes them appear interesting, well-liked and attractive to their friends and peers is a primary goal.
Scientists have discovered evidence of the beginning of the Anthropocene, the newest geological epoch. The evidence came in the form of a "golden spike" found in the heartwood of the "loneliest tree in the world."
CRISPR hack transform?s cells into data recorders
Our knowledge of dinosaur evolution has completely changed in the last 10 years, and likely will in the next 10 again too.
Did humans domesticate themselves? Human ‘self-domestication’ is a hypothesis that states that among the driving forces of human evolution, humans selected their companions depending on who had a more pro-social behavior. Researchers found out new genetic evidence for this evolutionary process.
Study dispels notion that social media displaces human contact - A new study shows no evidence for the proposition that social media crowds out face-to-face communication with those who ought to matter most, our close friends and family members, debunking the social displacement hypothesis.
DNA secrets of how vampire bats became bloodthirsty
Franzmeier et al. show that greater left frontal hub connectivity within the fronto-parietal control network is associated with greater resilience of cognitive performance during early stages of autosomal dominant & sporadic Alzheimer’s disease.
Unconventional superconductor may be used to create quantum computers of the future
DNA analysis is giving clues to how the vampire bat can survive on blood alone. Vampire bats have key differences in genes involved in immunity and food metabolism compared with other bats.

Air Pollution from New and Shutdown Industries, a Big Danger to Public Health
Humans will actually react pretty well to news of alien life. Across multiple studies, researchers found that reactions were significantly more positive than negative, and more reward vs. risk oriented.
AAAS AMA: Hi, we're scientists from NOAA and research universities who analyze the sources of pollution and recently published a study in Science Magazine. Ask us anything!

Like the horse of Troy, scientists have developed a way to sneak synthetic cells right into tumor tissue, where they then begin producing cancer-fighting proteins from the inside. The technique was tested in both cell cultures and in mice, and found to be an effective treatment in both cases.
Researchers have developed a printing technique using cells and molecules normally found in natural tissues to create constructs that resemble biological structures, embedded in an ink similar to their native environment, that mimic body parts for tissue engineering or regenerative medicine.
A strip of paper can now indicate presence of pathogens, tumor DNA or any genetic signature of interest. 100-fold greater sensitivity, the ability to detect multiple targets at once, and other new features further enhance SHERLOCK's power for detecting genetic signatures- Broad institute, Harvard
"Our models indicate that between 1999 and 2015, half of the orangutan population (~100,000) was affected by logging, deforestation, or industrialized plantations. Although land clearance caused the most dramatic rates of decline, it accounted for only a small proportion of the total loss."
Women who work as cleaners or regularly use cleaning sprays or other cleaning products at home appear to experience a greater decline in lung function over time than women who do not clean, according to new research published in the American Journal of Respiratory and Critical Care Medicine.
Scientists Create a New Form of Light by Linking Photons. Photons typically don’t interact, but physicists bound three together in the lab. This new form of light could someday be used to build light crystals that could lead to intriguing new ways of communicating and computing
4725 Campmasta ELI5? I'm still working on my half sleeve tattoo and wondering if I now have cancer..... Thanks!

348 kungfoojesus As someone who reads lymphoscintigraphy and sees all manner of foreign objects, especially breast implants, leak and end up in lumpy nodes, this is completely unsurprising. That's where shit goes, I'm not sure what was expected. Edit: I think finding deposition in distant organs, the brain especially, would be interesting.
498 gnomes616 I have quite a few tattoos, and one of the pathologists I worked with said there was a correlation between tattoos and getting lymphoma later on. Many searches proved this untrue, but a different pathologist said it can make it more difficult to detect metastatic melanoma in lymph nodes (especially with dark ink).

16 Disco_Drew My wife had tattoo ink travel from her back to her tailbone and become a recurring cyst that had to be removed. Not cancer, but super uncomfortable.
55 BayChaCha More reading here... "Tattoo ink nanoparticles in skin tissue and fibroblasts". Starting points for the above article are: 1. Tattoo inks contain nanoparticles, which have higher levels of chemical activity than larger particles. 2. Not much research has been done into the toxicity of tattoo inks, so we know very little about the biochemical reactivity of ink particles with skin cells and tissues (plus constituent components, like fibroblasts and associated collagen fibrillar networks). 3. Ink manufactures are not obliged to disclose the contents of their ink. Interesting read. But it could be argued that mass tattoo uptake is peaking as cultural & fashion saturation points are reached. So any significant effects of chemicals being pumped into the dermis might only affect one or 2 generations (the recent upsurge in large-scale / populist tattoo usage) and then be forgotten as fashions move on.
