I write about the process of scientific discovery, peer review, funding for research and highlight selected new scientific articles in biomedical research and the social sciences.
Does morality depend on the time of the day? The study "The Morning Morality Effect: The Influence of Time of Day on Unethical Behavior" published in October of 2013 by Maryam Kouchaki and Isaac Smith suggested that people are more honest in the mornings, and that their ability to resist the temptation of lying and cheating wears off as the day progresses. In a series of experiments, Kouchaki and Smith found that moral awareness and self-control in their study subjects decreased in the........ Read more »

To celebrate Valentine's Day (as a geeky scientist), I decided to search the "Web of Science" database for published articles with the phrase "Valentine's Day" in the title.The article with the most citations was "Market-resistance and Valentine's Day events" published in the Journal of Business Research in 2009, by the authors Angeline Close and George Zinkhan. The title sounded rather interesting so I decided to read it. The authors reported the res........ Read more »
Have you ever wondered how the content of your dreams differs from that of your friends? How about the dreams of people raised in different countries and cultures? It is not always easy to compare dreams of distinct individuals because the content of dreams depends on our personal experiences. This is why dream researchers have developed standardized dream questionnaires in which common thematic elements are grouped together. These questionnaires can be translated into various languages and used........ Read more »
The 2010 floods were among the worst that Pakistan has experienced in recent decades. Sadly, the country is prone to recurrent flooding which means that in any given year, Pakistani farmers hope and pray that the floods will not be as bad as those in 2010. It would be natural to assume that recurring flood disasters force Pakistani farmers to give up farming and migrate to the cities in order to make ends meet. But a recent study published in the journal Nature Climate Change by Valerie Mueller ........ Read more »

Paying bills, filling out forms, completing class assignments or submitting grant proposals – we all have the tendency to procrastinate. We may engage in trivial activities such as watching TV shows, playing video games or chatting for an hour and risk missing important deadlines by putting off tasks that are essential for our financial and professional security. Not all humans are equally prone to procrastination, and a recent study suggests that this may in part be due to the fact that t........ Read more »

Reading literary fiction can be highly pleasurable, but does it also make you a better person? Conventional wisdom and intuition lead us to believe that reading can indeed improve us. However, as the philosopher Emrys Westacott has recently pointed out in his essay for 3Quarksdaily, we may overestimate the capacity of literary fiction to foster moral improvement. A slew of scientific studies have taken on the task of studying the impact of literary fiction on our emotions and thoughts. Some of t........ Read more »

A study of the prevalence of mental illness published in the Archives of General Psychiatry in 2005 estimated that roughly half of all Americans will have been diagnosed with a mental illness by time they reach the age of 75. This estimate was based on the DSM-IV criteria for mental illness, but the newer DSM-V manual will be released in 2013 and is likely to further expand the diagnosis of mental illness. The DSM-IV criteria had made allowance for bereavement to avoid diagnosing people who were........ Read more »

Two scientific papers that were published in the journal Nature in the year 2000 marked the beginning of engineering biological circuits in cells. The paper "Construction of a genetic toggle switch in Escherichia coli" by Timothy Gardner, Charles Cantor and James Collins created a genetic toggle switch by simultaneously introducing an artificial DNA plasmid into a bacterial cell. This DNA plasmid contained two promoters (DNA sequences which regulate the expression of genes) and two rep........ Read more »
Geteiltes Leid ist halbes Leid ("Shared sorrow is half the sorrow") is a popular German proverb which refers to the importance of sharing bad news and troubling experiences with others. The therapeutic process of sharing takes on many different forms: we may take comfort in the fact that others have experienced similar forms of sorrow, we are often reassured by the empathy and encouragement we receive from friends, and even the mere process of narrating the details of what is troubling........

Beware of what you share. Employers now routinely utilize internet search engines or social network searches to obtain information about job applicants. A survey of 2,184 hiring managers and human resource professionals conducted by the online employment website CareerBuilder.com revealed that 39% use social networking sites to research job candidates. Of the group who used social networks to evaluate job applicants, 43% found content on a social networking site that caused them to not hire a ca........ Read more »

The recent study "The Impact of Sustained Engagement on Cognitive Function in Older Adults: The Synapse Project" published in the journal Psychological Science by the psychology researcher Denise Park and her colleagues at the University of Texas at Dallas is an example of an extremely well-designed study which attempts to tease out the benefits of participating in a structured activity versus receiving formal education and acquiring new skills. The researchers assigned subjects with a mean age ........ Read more »

Temporal order can be assessed in a rather straightforward experimental manner. Research subjects can be provided sequential auditory clicks, one to each ear. If the clicks are one second apart, nearly all participants can correctly identify whether or not the click in the right ear came before the one in the left ear. It turns out that this holds true even if the clicks are only 100 milliseconds (0.1 seconds) apart. The threshold for being able to correctly assign a temporal order to such brief........ Read more »

Land grabbing refers to the large-scale acquisition of comparatively inexpensive agricultural land in foreign countries by foreign governments or corporations. In most cases, the acquired land is located in under-developed countries in Africa, Asia or South America, while the grabbers are investment funds based in Europe, North America and the Middle East. The acquisition can take the form of an outright purchase or a long-term-lease, ranging from 25 to 99 years, that gives the grabbing entity e........ Read more »
Research projects evolve in a fortuitous manner, often guided by a convergence of novel observations, intuition, helpful colleagues and unique personal circumstances. It is precisely this constellation that prompted two cardiologists to study the mitochondrial networks in lung cancer cells.... Read more »

When we observe an interaction between two other human beings (Person A and Person B), we sometimes draw conclusions about the personality traits or character of these two individuals. For example, if we see that Person A is being rude to Person B, we may be less likely to trust Person A, even though we are merely "third-party" evaluators. i.e. not directly involved in the interaction. Multiple studies with humans have already documented such third-party social evaluation, which can ev........ Read more »

The concept “superiority illusion” refers to the fact that people tend to judge themselves as being superior to the average person when it comes to positive traits such as intelligence, desirability or other personality traits. This is mathematically not possible, because in a normally distributed population, most people cannot be above average. The “superiority illusion” belongs to a family of positive illusions, such as the “optimism bias”, which is characte........ Read more »

Whether we cruise the internet, turn on the TV or simply open up our email Inbox, we are bound to encounter advice regarding obesity and weight loss. The problem is that a lot of the circulated opinions about obesity and weight gain are only poorly supported by medical and scientific evidence. The recent paper “Myths, Presumptions, and Facts about Obesity” published in the New England Journal of Medicine on January 31, 2013 by Krista Casazza and colleagues investigates popular notion........

The researchers Jan-Emmanuel De Neve and Andrew Oswald decided to study the link between happiness and income from a very different angle. Instead of asking whether more money leads to more happiness, they reversed the question and asked whether more happiness leads to more money. In the paper “Estimating the influence of life satisfaction and positive affect on later income using sibling fixed effects” published in the Proceedings of the National Academy of Sciences, De Neve and Osw........

Maintaining regular face-to-face contact with family members can be rather challenging because nowadays families are often geographically dispersed. It takes time, money and effort to travel and visit family members. The famous British anthropologist and evolutionary psychologist Robin Dunbar at Oxford University and his colleagues investigated how far people were willing to travel to see their relatives. Their results were published in the open access journal PLOS One “Going That Extra Mi........ Read more »
