The term placebo effect describes an improvement in the condition of a patient after being given a placebo--an inert substance (e.g. sugar pill) the patient expects may hold some benefit for him. The placebo effect has long been recognized as an unavoidable aspect of medical treatment. Physicians before the 1950s often took advantage of this knowledge by giving patients treatments like bread pills or injections of water with the understanding that patients had a tendency to feel better when they........

Most parents don’t want to think about their children as depressed, but that can be a deadly mistake. Short of clinical diagnosis through cost prohibitive therapy, there is no real way to tell if a child is at risk for depression. However, according to new research from Binghamton University , how much a child’s pupil dilates in response to seeing an emotional image can predict his or her risk of depression over the next two years....

While filleting a bass I found a dead snake inside, when the fish was caught it was a healthy fighting fish. My question is: Is it safe to eat the fish? Thanks,
You better believe that this e-mail caught my attention. It reminded me of this letter about whether it was safe to eat a fish that had been bitten by a Cottonmouth. In that case, I probably would not eat the fish. But, I did... Read more »

If you already think everything at the bottom of the ocean is slightly terrifying, Iosactis vagabunda won't change your mind. It's transparent, can tunnel underground, and hunts animals 15 times its size. And scientists are now realizing that there might be way, way more of these roaming killers than they'd previously thought.
Iosactis vagabunda lives on the Porcupine Abyssal Plain, a seabed southwest of Ireland that ranges from 4,000 to nearly 5,000 meters deep. The species was alread........ Read more »

One the early things I was taught in my neuroscience training was that new-onset visual hallucinations need to be assessed for medical or "organic causes".Auditory hallucinations were felt to be more characteristic of schizophrenia.One medical disorder linked to visual hallucinations is dementia with Lewy bodies (DLB). DLB is second to Alzheimer's disease in producing neurodegenerative dementia. Visual hallucinations is a hallmark of DLB and is found in up to 70% of clinical samples with th........ Read more »

Human error is now the leading cause of plane crashes, and one of the principal factors that provokes pilots to make mistakes is stress. Some pilots cope heroically in the face of stress, such as Chesley Sullenberger who steered his plane and passengers to safety, landing on the Hudson river after a double engine failure. Others fare less well, with sometimes fatal results. Knowing in advance how pilots will respond to stressful situations is therefore of paramount of importance to flight safety........ Read more »

"Parents of children with ASD [autism spectrum disorder] living in Stockholm, Sweden in 2006 were more likely to be on sick leave, not in the labor force, or earning low income when compared to parents who did not have a child with ASD and these results remained after adjusting for familial socioeconomic factors and parental psychiatric care."That was the rather grim conclusion reached by Miranda McEvilly and colleagues  (open-access) following their analysis of families taking........

Providers of mental-health services still rely on intervention techniques such as physical restraint and confinement to control some psychiatric hospital patients, a practice which can cause harm to both patients and care facilities, according to a new study from the University of Waterloo. The study found that almost one in four psychiatric patients in Ontario hospitals are restrained using control interventions, such as chairs that prevent rising, wrist restraints, seclusion rooms or acute con........

Flu vaccines can be something of a shot in the dark. Not only must they be given yearly, there’s no guarantee the strains against which they protect will be the ones circulating once the season arrives.
