Have you ever been at a party with lots of people chatting away, when for some unexplainable reason you felt compelled to turn and look at the front door of your friend's house...and just as you were looking, someone was just coming in from outside and closing the door? You couldn't have heard the door open since there was so much noise already inside - more likely you noticed that other people were looking at the front door. All of this probably happened without any explicit intention or focu........ Read more »

Everyone knows someone who likes to listen to some music while they work. Maybe it’s one of your kids, listening to the radio while they try to slog through their homework. Maybe it’s an uncle, playing his favorite record as he reads a book. Or maybe, god forbid, it’s a college senior browsing his iTunes as he desperately writes a last-minute blog post for his psychology seminar. Either way, they’re not alone – it’s a widely held popular belief that listening ........ Read more »

Who’d have thought we’d have gotten all this way in science and never studied whether money can buy happiness? Well, in fact, this HAS been studied, but the results have almost always been inconclusive. This probably has a lot to do with how it’s being studied, what ranges of monetary income you’re talking about, and [...]... Read more »

The alarming case of the cross-billed chickadees – and crows, nuthatches and woodpeckers — began at two birdfeeders. In 1998, Alaskan biologists got reports of chickadees with grossly elongated beaks snacking at feeders in two widely separated parts of the state. Soon, birds with similar deformities began showing up across Alaska and nearby regions. Now, […] Read More »... Read more »

Earlier this year, the state of Wisconsin considered adding Lactococcus lactis as the state microbe. Wisconsin is known as America’s Dairyland, and L. lactis is part of the cheese-making process. While its run to become the state microbe was ultimately unsuccessful, I wanted to learn more about the L. lactis bacterium. A quick search through PubMed yielded an intriguing paper by Lei et al., and it had nothing to do with converting milk to cheese. ... Read more »

The dissemination of science follows the conventional route of rigorous peer-review followed by publication in an accredited scientific journal.

Scientific papers of questionable authority, [...]... Read more »

Losing weight and keeping it off, for most people, means reducing their caloric intake and maintaing a calorie-reduced diet for as long as they plan to keep the weight off (a rare few can depend exclusively on exercise alone to lose and keep weight off - most of us can’t).
This means, they will either have [...]... Read more »

If you want to get a Siamese fighting fish (Betta splendans) like this, show it another fish...
...or its own reflection.
Famously, very few animals understand reflections as representing themselves. There are veritable reams of papers written about the “mirror test” and how much it suggests about animal self-awareness, and therefore, animal consciousness.
Whether you agree with great apes or dolphins showing self-recognition in the mirror test, pretty much everyone agrees that fishes do........ Read more »

Just a quick post here about a paper that came out about a month or so ago: PLoS Biology: Genomic Fossils Calibrate the Long-Term Evolution of Hepadnaviruses
This paper, by Clément Gilbert, Cédric Feschotte is quite cool. In it they describe their work on "Paleovirology" where they look for viruses than have "endogenized" by inserting into the genome of some host species. This endogenization is important in particular when the endogenous form becomes inactive and thus, i........ Read more »

Loneliness is a complex set of emotions that encompasses feelings of social isolation, unfilled intimate needs, and heightened feelings of vulnerability. Though transient for some people, chronic loneliness can take a physical and psychological toll on individuals, leading to increased morbidity and mortality. Specifically, new research indicates that loneliness raises blood pressure – a silent [...]... Read more »

Cell biologists make amazing discoveries using cells grown flat on culture dishes, yet the cells in an organism grow and function in three dimensions. Some cell biologists use clever tricks to understand how cells function in three dimensions by using cells cultured in gels, and they find out very valuable information. Throughout biology there are many cases of oriented cell division, during which a cell orients the mitotic spindle on a specific axis. These cell divisions can occur throughout........ Read more »

Humans have been aware of optical illusions for a very long time. Indeed, recently, the study of illusions has provided psychology with many, many illusions. Colman (2006) states that broadly speaking, illusions fall into the following categories:Ambiguous figures, associative illusions, illusory contours, impossible figures, movement illusions, perspective illusions, space-time illusions, stereoscopic illusions, and visual aftereffects.Baldwin IllusionMany illusions actually were developed befo........

Plagiarism: The adoption or reproduction of original creations of another author (person, collective, organization, community or other type of author, including anonymous authors) without due acknowledgment.
Fabrication: The falsification of data, information, or citations in any formal academic exercise.

How far does corporate social responsibility go? While corporate social responsibility looks good on paper, how far are companies willing to not just talk the talk, but also walk the walk?

Each year, we hear that people are gaining weight and that chronic health problems like obesity, heart problems, and diabetes are on the rise. It's commonplace to ascribe these trends to personal lifestyle choices, such as the lack of exercise and diet, as well as the increasingly pervasive nature of fast food and processed, high-sugar foods.
However, there may [...]... Read more »
