It's not a secret that organic farms trade modern science for inefficiency in production and higher profit margins - but that does not count the 'intangibles' that go into organic farming, argue Terry Anderson and Henry Miller, and those higher margins should be accounted for in a revenue-neutral way.

A  psychological analysis of novice assassins has delved into how hitmen bury their feelings after a successful attack.

Hired killers don't deal with people, they are businessmen and they are doing a job, no different than a soldier in the military.

What makes us happy? Philosophers, psychologists and scientists have long pondered that question.

Psychologists believe they may have a solution that satisfies everyone in flow theory, a model that better preserves the approach to individual distinctiveness by considering the mental experience as a process that might foster the evolution or the involution of an individual through his daily experiences.

Some flavorings used in electronic cigarette liquid may alter important cellular functions in lung tissue, according to a presentation at the 2015 American Thoracic Society International Conference.

The changes in cell viability, cell proliferation, and calcium signaling are flavor-dependent so coupling these results with chemicals identified in each flavor could prove useful in identifying flavors or chemical constituents that might produce adverse effects in users.

Do we hear sounds as they are, or do our expectations about what we are going to hear shape the way sound is processed? 

Through the use of computational neuroscience models, Bournemouth University’s Dr. Emili Balaguer-Ballester and colleagues are trying to map the way that the brain processes sound.

This is a question that is frequently asked on Quora, with a different date each time. We get a fair number of quite worried people asking this question, in all seriousness, concerned that Earth is about to be hit by a giant impactor. Sometimes they have read sensational stories by online papers that should know later.

It is easy to keep up to date with potential impact dates by visiting this page, automatically updated for the Sentinel program: Current Impact Risks. Just look and see if there are any entries coloured orange or red. Then look for the predicted date of impact. So far this has never happened.

Light-emitting diodes are the future, and will quickly bypass government-mandated and subsidized compact fluorescent bulbs and the prospect of wearing a Haz-Mat suit if you break one. Why be limited to bulbs, though?

Why not a light-emitting fork? 

Physicist Amir Asadpoordarvish of Umeå University in Sweden did just that, using new light-emitting electrochemical cells (LECs) sprayed onto a substrate that emit light using the current from an ordinary battery. A LEC is a solid-state thin-film device, which comprises an active material sandwiched between a cathode and an anode as its key constituent parts. To-date they have been fabricated on heavy, rigid parts.

In 1989 Ellen Stohl, who had become a wheelchair user after a car accident, appeared in an eight-page spread in Playboy magazine. She had pushed to do so, she explained later, because it was important for her to express her right to sexuality. “Sexuality is the hardest thing for a disabled person to hold on to,” she said in a TV interview. “I am a woman more than a wheelchair.”

Regarding Playboy owner Hugh Hefner, she added: “He believed that I could have the same sexual voice as women without disabilities.”

The United States remains mired in an economic downturn, with over 90 million unemployed and many of the employed making less than they made before 2009. The knock-on effects of the economic downturn have been explored in economy and psychology. Now researchers are examining the effects of unemployment on an even darker subject - cancer mortality.

One would think that dealing with unemployment was challenge enough. But according to the latest research published in ecancermedicalscience, rises in unemployment are associated with significant increases in prostate cancer mortality.
