12:20 AM | Does Botox affect emotion perception?
We all know that Botox makes us look at people a little differently (why isn’t her forehead moving??). Turns out Botox may make those injected look at little differently at us, too. Botox works by temporarily paralyzing facial muscles. Concern … Continue reading →

6:09 PM | Round trip ticket to the science of psychedelics
The latest edition of The Psychologist is a special open-access issue on the science and social impact of hallucinogenic drugs. There’s an article by me on culture and hallucinogens that discusses the role of hallucinogenic drugs in diverse cultures and which also covers how cultural expectations shape the hallucinogenic experience – from traditional Kitanemuk society […]

The flamboyant cuttlefish lives up to its name with its complex passing cloud display, in which bands of color travel across its body. New research characterizes details of this display and suggests how the cuttlefish might accomplish it. Read about it in my latest Zoologic post, Secrets of the Flamboyant Cuttlefish’s Display .

3:26 PM | What fraction of our brain do we use?
There is a long-standing “science myth” claiming that “we only use ten percent of our brain”.  The myth dates back many years, and rises and falls in popularity, but has recently been reinvigorated by the movie Lucy, where it is asserted by the authoritative voice of Morgan Freeman.  It has been debunked so many times … Continue reading »

2:58 PM | Diagnostic Profile in Pathological Gamblers
Behavioral disorders like pathological gambling (PG) rarely occur alone as a single uncomplicated disorder.In a previous post, I noted the overlap of PG with personality disorder, anxiety disorder, depression, bipolar disorder and substance abuse.A recent study from Germany adds to our knowledge of the general diagnostic profile in the PG population.Erbas and Buchner reviewed German national data sources and other German studies to come up with a series of findings:Twelve month prevalence rates […]

It appears form the article cited here (1) that diagnosis is often flawed in many studies and that the so-called diagnosis of co-morbidity is […]

9:06 AM | 10 Surprising Things Babies Can Do
Human infants are helpless. At first they can't even support the weight of their own heads. Crawling and walking take months to master. Compare this with the sprightly newborns of other mammals, such as kittens and foals, up and about within an hour of their birth. There are several theories as to why human development is so protracted - among them that this extra time is required for the human brain to develop. This post side-steps such debates and focuses on 10 studies hinting at the […]

11:30 PM | Married Couples Who Smoke Pot Have Fewer Domestic Violence Incidents
A look at 634 couples found that the more often they smoked marijuana, the less likely they were to engage in domestic violence.   The scholars attempted to clarify inconsistent findings about domestic violence among pot-smoking couples that primarily has been based on cross-sectional data (i.e., data from one point in time). Looking at couples over the first nine years of marriage, the study found: More frequent marijuana use by husbands and wives (two-to-three times per month or […]

11:06 PM | Holographic Noise Speculation: Maybe You Are A 2-D Hologram
The Holometer, an experiment at Fermi National Accelerator Laboratory, has started collecting data but researchers are not going to wait to start their media blitz; they are throwing out  mind-bending speculation, like that perhaps we live in a hologram. Much like characters on a television show would not know that their seemingly 3-D world exists only on a 2-D screen, we could be clueless that our 3-D space is just an illusion. The information about everything in our universe […]

10:17 PM | Ionic Liquids: Busting Through Biofilm Shatters Defenses Of Serious Skin Infections
Biofilms are the first line of defense for harmful bacteria and make the treatment of skin infections especially difficult because microorganisms protected in a biofilm have antibiotic resistance and recalcitrance to treatment. Biofilm-protected bacteria account for some 80 percent of total bacterial infections in humans and are 50 to 1,000 times more resistant to antibiotics than simpler bacterial infections.  Biofilms often persist in the periphery of an actual wound, beneath an […]

9:01 PM | Sorting Cells With Sound
Researchers have devised a new way to separate cells by exposing them to sound waves as they flow through a tiny channel. Separating cells with sound offers a gentler alternative to existing cell-sorting technologies, which require tagging the cells with chemicals or exposing them to stronger mechanical forces that may damage them. Their device, about the size of a dime, could be used to detect the extremely rare tumor cells that circulate in cancer patients' blood, helping doctors predict […]

8:38 PM | Resilience Management: What The Bubonic Plague Can Teach Us About Ebola
In the 14th century, Venice was in many ways still a world power in its own right. The days when it could topple kingdoms using commerce were behind it, but it was still an important trade destination. In that period, trade meant ports and ports meant the Bubonic Plague in 1347. When it hit, some tried prayer, some tried hunting vampires, but then officials quickly began to utilize what we would now call resilience management: rather than trying to target a poorly understood […]

Opened in 1981, Japans first driverless, fully automated train pulls out of Sannomiya station, guided smoothly along elevated tracks that stand precariously over the bustling city streets below, across the bay to the Port Island.The island, and much of the city, was razed to the ground in the Great Hanshin […]

6:31 PM | Disillusioned Churchgoers Undergo A Moral Identity Crisis
Dsillusioned churchgoers may find it increasingly difficult to remain associated with their church, yet many also find it difficult to leave.  They have not only a moral identity crisis but deep identity crises as their most important relationships and beliefs are put at risk.  The authors of a paper in the Journal of Consumer Research conducted interviews with people who identify as former churchgoers and asked them to reflect on their experiences in leaving the church and the […]
