Wikipedia is crowdsourced knowledge and therefore discourages people from writing about themselves. As a result, 60 percent of Wikipedia articles about companies contain factual errors, according to research published in Public Relations Journal.

Marcia W. DiStaso, Ph.D., assistant professor of public relations at Penn State University, surveyed 1,284 public relations people from the Public Relations Society of America's (PRSA). Results of the survey indicate a gap exists between public relations companies and Wikipedia concerning the proper protocol for editing entries.

Whether you are concerned about Mayans, a worldwide infrastructure collapse or an exploding supervolcano, science has some good news for your doomsday preparation - sunlight and a twist of lime are an inexpensive and effective way to quickly improve the quality of your drinking water.

Researchers have found that adding lime juice to water while using a solar disinfection method removed detectable levels of harmful bacteria such as Escherichia coli (E. coli) significantly faster than solar disinfection alone. 

Proteins are large, organic - in the science sense of organic, not the food marketing sense -  molecules that help us to convert food into energy, supply oxygen to our blood and muscles and drive our immune systems. 

Proteins consist of one or more polypeptides, chains of amino acids held together by peptide bonds. If a protein in water is heated to temperatures approaching the boiling point of water, these chains will lose their structure and the protein will denature (unfold). 

We created clocks and calendars to give people a common way to communicate about the future and the past and about when to have dinner.  But time is, as they say, relative.  A clock on top of a mountain moves differently than one at sea level - that's gravitational time dilation. NIST researchers have even been able to show that tall people age differently than short ones. And if you lived your life in a car traveling 20 miles per hour, you would age slower than people who just walk around. Time is not only relative in physics, it is relative in culture.  We feel like time moves faster the older we get.

People with Body Dysmorphic Disorder (BDD) have an obsession relating to their body image, where they believe that they have a defect in their appearance.

BDD is estimated to affect one to two per cent of the population. Individuals with BDD engage with time-consuming compulsive behaviors such as mirror-checking, applying make-up to camouflage and seeking reassurance about their appearance.

Noise levels, fine particulate matter that leads to smog and traffic volumes are a big concern to  urban planners and residents now but they will be even bigger issues in the 'city of tomorrow'.

Three-dimensional tools will soon make it easier to simulate those issues: as the user virtually moves through his city, the corresponding data are displayed as green, yellow or red dots.
