| Internet communities can teach amateurs to build personalized governments Posted: 12 Jul 2019 09:02 AM PDT Self-governing internet communities, in the form of games, social networks or informational websites, create their own rule systems that help groups of anonymous users work together. |
| Insects feel persistent pain after injury, evidence suggests Posted: 12 Jul 2019 09:02 AM PDT Scientists have known insects experience something like pain, but new research provides compelling evidence suggesting that insects also experience chronic pain that lasts long after an initial injury has healed. |
| New gene linked to healthy aging in worms Posted: 12 Jul 2019 09:02 AM PDT Damage to gene causes impaired movement in adult worms. |
| Dentistry: Root canal work not so bad after all Posted: 12 Jul 2019 09:02 AM PDT Root canal work is not as bad as people think when compared to other dental procedures. Self-reporting of their dental health suggests that patients find the procedure no worse than other dental work which overturns the popular belief that root canal work is the most unpleasant dental treatment. |
| Early arrival of spring disrupts the mutualism between plants and pollinators Posted: 12 Jul 2019 09:02 AM PDT Early snowmelt increases the risk of phenological mismatch, in which the flowering of periodic plants and pollinators fall out of sync, compromising seed production. |
| 'The way you move': Body structure brings coordinated movement Posted: 12 Jul 2019 09:02 AM PDT A computer model shows that a starfish-like animal can coordinate rhythmic motion based on body structure without the brain telling them to do so. This provides insights useful for physiology and robotics. |
| Which is the perfect quantum theory? Posted: 12 Jul 2019 09:02 AM PDT For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? Researchers have now successfully deployed artificial neural networks for image analysis of quantum systems. |
| Better policies around toxic chemicals urged Posted: 12 Jul 2019 09:02 AM PDT Researchers contend that failures to protect human and environmental health from toxic chemicals result from flawed governance, and lay out a plan for improved policies. |
| Preterm babies are less likely to form romantic relationships in adulthood Posted: 12 Jul 2019 09:02 AM PDT Adults who were born preterm (under 37 weeks gestation) are less likely to have a romantic relationship, a sexual partner and experience parenthood than those born full term. The meta-analysis with data from up to 4.4 million adult participants showed that those born preterm are 28% less likely to ever be in a romantic relationship. |
| HIV: Reprogramming cells to control infection Posted: 12 Jul 2019 09:02 AM PDT Following research on cohorts, scientists have described the characteristics of CD8 immune cells in these 'HIV controller' subjects. The unique antiviral power of these immune cells can be attributed to an optimal metabolic program that confers persistence and the ability to react effectively against infected cells. Working ex vivo, the scientists successfully reprogrammed cells from infected non-controller individuals to give them the same antiviral potency as controllers' cells. |
| Fewer than half of US adults exposed to court-ordered anti-smoking advertisements Posted: 12 Jul 2019 09:02 AM PDT The tobacco industry's court-ordered anti-smoking advertisements reached just 40.6 percent of US adults and 50.5 percent of current smokers in 2018, according to new research. Exposure to the advertisements was even lower among certain ethnic and socioeconomic subgroups historically targeted by tobacco industry marketing. |
