Men and boys with older sisters are less competitive

by BPS Research Digest in BPS Research Digest

One of the longest-debated and most studied issues in psychology is whether and how our personalities are affected by our birth order and the sex of our siblings. A problem with much previous research is that it's depended on people self-reporting their own personality, or on siblings or parents providing the personality ratings. These ratings are prone to subjectivity and skewed by people's expectations about how, say, a younger sibling ought to behave.A new study focused on one particular find........ 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 »

Earth Day Turns 45

by Whitney Campbell in Green Screen

Ever since Earth Day was first celebrated in 1970, the event has adapted to the environmental issues of the times. During its inaugural year, 20 million people across the U.S. attended teach-ins and learned about the quality of the nation's water. Months earlier, coastal Santa Barbara had experienced an oil spill, while Time photographs had brought the fires of Ohio's Cuyahoga River to the country's attention. The teach-ins prompted widespread awareness of the pollution, and withi........ Read more »

Psychologists study burglars' expertise

by BPS Research Digest in BPS Research Digest

Their actions are criminal and they cause untold misery, but repeat burglars are skilled at what they do and in that sense they are experts. By studying this expertise we can learn to better secure our properties against the threat of theft, and detectives can learn to spot the signature trail of an experienced robber.Most previous research in this area has relied on interviews with burglars about their strategies: a limited approach. A new study is more compelling. Claire Nee and her team recru........ Read more »

why the great void didn’t cause the cold spot

by Greg Fish in weird things

Remember the anomalous Cold Spot, the bizarre, low temperature area spotted in the maps of the Cosmic Microwave Background Radiation, or CMBR for short, the echo the Big Bang which gives us a very high level overview of the structure of our universe?

Recently we blogged about an emerging demographic subgroup: the lumbersexual. After reading the flurry of mainstream media articles about this group, here is how we described them: “As far as we can tell, the lumbersexual is an urban male (typically White and heterosexual) who dresses like a lumberjack even though he is far from a […]

MMR vaccine was not associated with increased risk of autism

by Paul Whiteley in Questioning Answers

"In this large sample of privately insured children with older siblings, receipt of the MMR [measles-mumps-rubella] vaccine was not associated with increased risk of ASD [autism spectrum disorder], regardless of whether older siblings had ASD. These findings indicate no harmful association between MMR vaccine receipt and ASD even among children already at higher risk for ASD."That was the conclusion reached in the study by Anjali Jain and colleagues [1] (open-access) based on........
