9:47 AM | Why we need to be more accurate in diagnosing co-morbidity.
In this blog we have repeatedly queried whether the co-occurrence of so-called co-morbidities with substance use disorders (SUDs) is as high as reported in many studies (1). In a blog from yesterday Are most co-morbidities really substance-induced disorders?  that diagnosis is often flawed in many studies and that the so-called diagnosis of co-morbidity is not borne […]

8:15 AM | Managers, conservatives, Europeans and the non-religious show higher levels of psychopathic traits
Christian Bale played the archetypalpsychopath in American Psycho (2000).Mention psychopathic personality traits and the mind turns to criminals. The archetype is a callous killer who entraps his victims with a smile and easy charm. However, recent years have seen an increasing recognition that psychopathic traits are on a continuous spectrum in all of us (akin to other personality factors like extraversion), that they don't always manifest in criminality, and that in certain contexts, they may […]

5:18 AM | Dense Galactic Core Shows Early Construction Of Giant Galaxy
Astronomers have caught a glimpse of the earliest stages of massive galaxy construction - a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate. A fully developed elliptical galaxy is a gas-deficient gathering of ancient stars theorized to develop from the inside out, with a compact core marking its beginnings. Because the galactic core is so far away, the light of the forming galaxy that is observable from Earth was actually created 11 […]

My colleague Maria Pereyra died today.I was on the search committee that helped hire her, and I was happy to have her in the department.

8:28 PM | Xenon Gas Can Erase Traumatic Memories
Xenon gas is commonly used for diagnostic inhalation because of its anesthetic properties but more recently it has been used by the Russians to cheat in the Olympics, and the cycling community has followed suit, because of its EPO - Erythropoietin - hormone producton ability. It may also be a treatment for post-traumatic stress disorder (PTSD) and other memory-related disorders, according to a new paper in PLOS One.read more

8:01 PM | Brain Networks Hyper-Connected In Depressed Young Adults
Functional magnetic resonance imaging (fMRI) has led University of Illinois at Chicago scholars to conclude that young adults who previously experienced the mental illness have hyper-connected emotional and cognitive networks in the brain. The college students were ages 18 to 23 while they were in a resting state. 30 un-medicated young adults who claimed to have experienced depression and 23 healthy controls were used in the study, which has published in PLOS ONE. "We wanted to see if the […]

4:21 PM | Where To Search On Mars For Droplets, & Shallow Flows Of Liquid Water - Where Microbial Life May Flourish
Where should we go, on Mars, to look for droplets and streaks of present day liquid water? You may have heard of the "warm seasonal flows", and the recent "swimming pools of bacteria". However,  there are several other promising ideas for habitats such as the "Flow like features", the advancing sand dunes bioreactor, and possibilities for life using the humidity of the night time air on Mars. It's an exciting field with many new discoveries and ideas every year, and it is hard to keep […]
