Physical exercise for ADHD meta-analysed

by Paul Whiteley in Questioning Answers

In today's short blog post I'd like to bring to your attention the findings reported by Cerrillo-Urbina and colleagues [1] who, upon gathering the available peer-reviewed evidence, suggested that: "short-term aerobic exercise, based on several aerobic intervention formats, seems to be effective for mitigating symptoms such as attention, hyperactivity, impulsivity, anxiety, executive function and social disorders in children with ADHD [attention deficit hyperactivity disorder]."Reviewing and........

Vampire Plants: Sucking Life into the Community

by Melissa Chernick in Science Storiented

I would like to introduce you to the yellow rattle (Rhinanthus minor). This little plant has pretty yellow flowers that belie a dark secret: it is a vampire plant. Okay, technically, it is a hemiparasite. The yellow rattle has green, photosynthetic leaves to make its own food, but its roots latch onto those of nearby plants to steal their water and nutrients. I guess you could say that it hasn’t gone full parasite. So what’s wrong with a little leaching of material from your neighbor? Must b........ Read more »

Churchgoing has been on the decline for decades in Western nations: here’s why

by Tom Rees in Epiphenom

It’s a fact that, in the West at least, fewer people are going to religious services than they used to a few decades ago. Countries do follow different trajectories – secularization happened first in the Protestant countries of Northern Europe and Australia, and more recently the Catholic countries of Europe. The Americas have fought the [Read More...]... Read more »

Cobalt speeds us up and slows us down

by Rosin Cerate in Rosin Cerate

Cobalt is a relatively hard and brittle metal that can be used to make fancy magnets and is typically found along with copper and nickel in the Earth's crust. It's silver-white in appearance, but when combined with aluminum and oxygen it forms pretty blue compounds such as cobalt blue. Owing to its various effects on the human body, our lives can intersect with cobalt in many ways. One of the things the metal or molecules that contain it tend to do is alter our mobility, speeding us up or s........ Read more »

Improving memory through deep brain stimulation: the very first steps

by Pierre Megevand in Neuroscience and Medicine

Deep brain stimulation (DBS) has been one of the biggest success stories of clinical neuroscience, thanks to its ability to reverse the symptoms of tremors, Parkinson’s disease, and a growing number of neurological and psychiatric conditions without any of the unwanted side effects of pharmacological therapies. Because DBS could in theory modulate any cerebral structure or network, researchers are starting to think about targeting cognitive functions such as memory. In a study published re........

The human sex ratio at conception and the conception of scientific “facts”

by steven orzack in the Node

Few things interest many people more than sex. For some, this means interest in practices and partners. For others, it means producing a son. There is an ocean of claims about how to do this. A quick Google search reveals claims that a woman can up the odds of a son by taking cough syrup, […]... Read more »

Largest-ever study of parental age and autism finds increased risk with teen moms

by Dr. Jekyll in Lunatic Laboratories

The largest-ever multinational study of parental age and autism risk, funded by Autism Speaks, found increased autism rates among the children of teen moms and among children whose parents have relatively large gaps between their ages. The study also confirmed that older parents are at higher risk of having children with autism. The analysis included more than 5.7 million children in five countries.... Read more »

What Happens When 28,000 Volunteers Are Set Loose in the Virtual Serengeti

by Elizabeth Preston in Inkfish



What's a scientist to do with 1.2 million photos, most of grass but some containing valuable data about endangered animals? Turn the whole thing over to the public, if you're the creators of Snapshot Serengeti. This project caught the attention of tens of thousands of volunteers. Now their work has produced a massive dataset that's already helping scientists in a range of fields.



Most online citizen science involves a degree of tedium—counting craters, tracing kelp mats. But Snapshot ... Read more »

Familial autoimmune disease and offspring autism risk

by Paul Whiteley in Questioning Answers

"An overall increased risk of autism in children with family history of ADs [autoimmune diseases] was identified."That was the bottom line of the "systematic review and meta-analysis" carried out by Shunquan Wu and colleagues [1] summarising the "current evidence on the relationship between family history of autoimmune diseases (ADs) and risk of autism in children." Autoimmune disorders by the way, are the various conditions that come about when the body fails to recognise self as........ Read more »

The health effects of homophobia

by Dr. Jekyll in Lunatic Laboratories

Homophobia, since people are (finally) stigmatizing racism, it’s just another excuse to be able to treat people who are slightly different like they are garbage. To that end, I have bad news for gay and bisexual men living in European countries with strong attitudes and policies against homosexuality are far less likely to use HIV-prevention services, test for HIV, and discuss their sexuality with health providers, according to research led by Yale School of Public Health (YSPH)....

Your Brain Is Bigger In The Morning

by Neuroskeptic in Neuroskeptic_Discover

The brain shrinks over the course of the day, ending up smaller in the evening - before returning to its full size the next morning. That's according to a neat new study based on an analysis of almost 10,000 MRI scans. It's published today in Neuroimage.



Kunio Nakamura and colleagues of the Montreal Neurological Institute examined 3,269 scans from multiple sclerosis trials and 6,114 from the ADNI Alzheimer's disease project. This makes it the biggest neuroscience study I can think of.

Stroke prevention with the Mediterranean diet

by William Lu in The Quantum Lobe Chronicles

Fad diets abound, but none appear to be as positively impactful to health as the Mediterranean diet. Even the likes of Jennifer Garner, Elizbath Hurley, and Catherine Zeta-Jones adhere it, and they are all very attractive. Although it won't help increase attractiveness, it may contribute to preventing strokes. The diet consists of eating primarily plant-based foods such as fruits, vegetables, whole grains, legumes, and nuts. The health benefits of eating such foods were confirmed in an epidemiol........
