 Exercise Meaningful in Having Good Mental Health

In this cross-sectional study, we analysed data from 1?237?194 people aged 18 years or older in the USA from the 2011, 2013, and 2015 Centers for Disease Control and Prevention Behavioral Risk Factors Surveillance System survey. We compared the number of days of bad self-reported mental health between individuals who exercised and those who did not, using an exact non-parametric matching procedure to balance the two groups in terms of age, race, gender, marital status, income, education level...

 Greek Philosophical Science of Categorization was Aesthetic

It is not meant that the Greeks had more respect for the function of perception through the senses than has modern science, but that, judged from present practice, they had altogether too mucfy respect for the material of direct, unanalyzed sense-perception. They were aware of its defects from the standpoint of knowledge. But they supposed that they could correct these defects and supplement their lack by purely logical or "rational" means. They supposed that thought could take the material...

 China to Rate Online Behaviour in Social Credit System

Chinese internet firms are definitely interested, as Ant Financial, a subsidiary of ecommercegiant Alibaba, recently showed. To its popular app Alipay it added a new service which rated a person's credit worthiness on a scale of 350 to 950 points. This score is not only determined by one's lending behavior, but also by hobbies and friends. If friends have a poor lending reputation, this reflects badly on the person, just as prolonged playing of video games. Buying diapers indicates responsibi...

 Healthy Lifestyle Changes Increase Telomerase Length by 10%

Methods This follow-up study compared ten men and 25 external controls who had biopsy-proven low-risk prostate cancer and had chosen to undergo active surveillance. Eligible participants were enrolled between 2003 and 2007 from previous studies and selected according to the same criteria. Men in the intervention group followed a programme of comprehensive lifestyle changes (diet, activity, stress management, and social support), and the men in the control group underwent active surveillance ...

 Why Do Journals Get It Wrong?

Why do studies end up with wrong findings? In fact, there are so many distorting forces baked into the process of testing the accuracy of a medical theory, that it’s harder to explain how researchers manage to produce valid findings, aside from sheer luck. To cite just a few of these problems: Mismeasurement To test the safety and efficacy of a drug, for example, what researchers really want to know is how thousands of people will fare long-term when taking the drug. But it would be unethical...

 Society Needs People Who Are Concerned With Ideas, Not Th...

Humanity certainly needs practical men, who get the most out of their work, and, without forgetting the general good, safeguard their own interests. But humanity also needs dreamers, for whom the disinterested development of an enterprise is so captivating that it becomes impossible for them to devote their care to their own material profit. Without the slightest doubt, these dreamers do not deserve wealth, because they do not desire it. Even so, a well-organised society should assure to such...

 We Have Finite Time to Spend in Life

At IndieCade in October 2011, Adam Saltsman, Canabalt's creator, discussed the notion of "time until death." All of us have a finite amount of time on earth, and any time we spend on a particular activity is time that we can't spend doing something else. This means that the time we spend gaming represents most of a game's cost of ownership, far more than any money that we spend. If that time is enjoyable (or rather, if its benefits outweigh its costs), then the game was worth our time. Value...

When we play games, we should play games that are fun, but also creative and challenging. Easy games are a complete waste of time, like watching TV. Hard games challenge us and make us grow.

 Alexander Graham Bell's Hypothesis

I have read somewhere that the resistance offered by a wire ... is affected by the tension of the wire. If this is so, a continuous current of electricity passed through a vibrating wire should meet with a varying resistance, and hence a pulsatory action should be induced in the current ... [corresponding] in amplitude, as well as in rate of movement, to the vibrations of the string ... [Thus] the timbre of a sound [a quality essential to intelligible speech] could be transmitted ... [and] th...

 The Science on the Path

A weed plucked at the side of the path might have found its way to the New World in a seventeenth century sailing ship. Scratches on a rocky ledge evoke colossal mountain-building events on the other side of the world millions of years ago that modified the planet's climate and caused glaciers to creep across New England. The oxygen atoms I suck into my lungs were forged in stars that lived and died long before the Earth was born. It is something of a cliche to say that everything is connecte...

 The Consumer is Not King

Marketers glibly say that the consumer is king, but in practice he's not. In the real world, experienced marketing and consumer-affairs hands will tell you, consumers aren't very good at protecting their own interests. They're too busy consuming, or working, or just living regular lives. The groups that claim to protect their interests often end up with their own agendas, which may have more to do with Washington power battles and fund-raising than with genuine consumer interests.
