Mental disorders do not predict violence, so please stop

by Dr. Jekyll in Lunatic Laboratories

When Sandy Hook happened, it was so shocking that to this day, some don’t actually believe it happened. Shortly after, something frustrating happened, the shooter was labeled with aspergers. This helped drive the mental health and violence connection to the point that Time came out with an article dispelling that myth. Even now according to new longitudinal study of delinquent youth, most psychiatric disorders – including depression — do not predict future violent behavior. The only except........ Read more »

Kids with autism: a highly [psychotropic] medicated group?

by Paul Whiteley in Questioning Answers

"In keeping with international studies this sample of children with ASD [autism spectrum disorder] was a highly medicated group."So said the results of the study reported by Kerry-Ann Louw and colleagues [1] back in 2013 who noted that approximately one quarter of their cohort were currently in receipt of "psychotropic medications". I don't want to linger too much on this topic given that such findings tally with other peer-reviewed reports including those with much larger partici........ Read more »

Diabetes drug found in freshwater potential cause of intersex fish

by Dr. Jekyll in Lunatic Laboratories

A medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish –or male fish that produce eggs. The study determined exposure to the diabetes medicine metformin causes physical changes in male fish exposed to doses similar to the amount in wastewater effluent.... Read more »

Marmoset Parents Teach Their Kids Not to Interrupt

by Elizabeth Preston in Inkfish



No one expects a human infant to slide into the world with a good grasp of grammar. Marmosets, another kind of chatty primate, are also poor conversationalists when they're young. But their parents seem to teach them how it's done. Young marmosets learn the cardinal rule of having a conversation: don't interrupt. And if they mess up, their parents give them the silent treatment.

Common marmosets (Callithrix jacchus) live in large family groups in the forests of Brazil. "Because marmosets ... Read more »

DSM-5 impacting on autism numbers

by Paul Whiteley in Questioning Answers

"Consistent with previous reviews, the majority of included studies indicated between 50 and 75 % of individuals will maintain diagnoses."That was one of the conclusions reached by Isaac Smith and colleagues [1] following their systematic review of studies comparing DSM-IV and DSM-5 criteria for autism spectrum disorder (ASD) and what the changes mean for eligibility for the label.Authors further reported that: "the greatest decreases [were] among high-functioning populations with IQs over ........

Scientists create worlds first genetically modified human embryos

by Dr. Jekyll in Lunatic Laboratories

A funny thing happened on the way to the publisher. In a world first, China has successfully created genetically modified human embryos. It was certainly an amazing piece of science, but the paper was rejected by both Nature and Science. Not because the study was flawed, or because the data was falsified, the paper was rejected for ethical reasons.... Read more »

Whooping cough: A small drop in vaccine protection can lead to a case upsurge

by Dr. Jekyll in Lunatic Laboratories

In 2012 the USA saw the highest number of pertussis (whooping cough) cases since 1955. New research finds that a likely explanation for this rise in disease is a drop in the degree of vaccine protection for each vaccinated individual. The team worked with 60 years of pertussis disease data to determine what best explained the recent increase in the disease.... Read more »

Does maternal asthma 'prime' for offspring neurodevelopmental disorder?

by Paul Whiteley in Questioning Answers

The paper from Jared Schwartzer and colleagues [1] (open-access) including a couple of familiar names on the authorship list (Charity Onore and Paul Ashwood) caught my attention recently. Based on mouse studies and the artificial induction of maternal allergy/asthma in pregnant mice, researchers reported that: "Activation of the maternal immune system with an allergy/asthma insult significantly perturbed developmental growth and species-typical behaviors in offspring." Further that the........ Read more »

Three tons of thyroid glands and a girl named Margaret Tracy: The odd origins of medications

by Rosin Cerate in Rosin Cerate

Drug discovery is a weird beast. These days, it's all about rational design, which means establishing a useful target in the body (e.g. an enzyme that does something that you'd like to stop or at least slow down) and then screening a truckload of chemicals for the best fit. A more traditional approach to drug discovery is to isolate and characterize chemicals present in plants of known medicinal value (e.g. morphine from the opium poppy). Then there is your classic scientific curiosity coupled w........ Read more »

Researchers find genetic link between overactive and underactive immune systems

by Dr. Jekyll in Lunatic Laboratories

In the largest genetic study to date of a challenging immunodeficiency disorder, scientists have identified a gene that may be a “missing link” between overactive and underactive immune activity. The gene candidate also plays a key role in autoimmune diseases such as type 1 diabetes, rheumatoid arthritis and even allergies.... Read more »

Video Tip of the Week: TargetMine, Data Warehouse for Drug Discovery

by Mary in OpenHelix

Browsing around genomic regions, layering on lots of associated data, and beginning to explore new data types I might come across are things that really fire up my brain. For me, visualization is key to forming new ideas about the relationships between genomic features and patterns of data. But frequently I want to take this […]... Read more »
