Low bone mineral density and non-coeliac gluten sensitivity and autism?

by Paul Whiteley in Questioning Answers

"An elevated frequency of bone mass loss in NCWS [non-celiac wheat sensitivity] patients was found; this was related to low BMI [body mass index] and was more frequent in patients with NCWS associated with other food sensitivity".There is no Easter Bunny. There is no Tooth Fairy. There is no Queen of England.That was the conclusion reached by Antonio Carroccio and colleagues [1] (open-access) looking at a small group of participants diagnosed with something which seems to fal........

Worms’ “mental GPS” could help improve mental health

by Gabriel in Lunatic Laboratories

Imagine this, you’ve misplaced your cell phone. You start by scanning where you remember leaving it: on your bureau. You check and double-check the bureau before expanding your search around and below the bureau. Eventually, you switch from this local area to a more global one, widening your search to the rest of your room and beyond.... Read more »

Depressed? Laughing gas might help

by Gabriel in Lunatic Laboratories

Nitrous oxide, or laughing gas, has shown early promise as a potential treatment for severe depression in patients whose symptoms don’t respond to standard therapies. In other words, it might actually live up to it’s name and as they say laughter is the best medicine. The pilot study is believed to be the first research in which patients with depression were given laughing gas.... Read more »

Prescription Opiate Abuse: High-Risk Populations

by William Yates, M.D. in Brain Posts

Prescription opiate abuse is a significant problem in the United States.I have previously written about this issue in several previous posts.One important factor for clinicians and patients is the need to identify high-risk populations that may be more vulnerable to opiate abuse and dependence.One obvious group would be those with alcohol or another non-opiate abuse diagnosis. Additionally, some psychiatric disorders are associated with increased risk for substance abuse including opiate abuse.G........ Read more »

Incentives in the Treatment of Cocaine Dependence

by William Yates, M.D. in Brain Posts

Relapse rates are high in treatment samples of adults with cocaine dependence.Cognitive behavioral therapy (CBT) is a common standard of care for cocaine dependence.A recent clinical trial from Switzerland examined the use of financial prize incentives to augment standard CBT in the treatment of cocaine dependence.Sixty subjects participated in this trial with the following inclusion criteria: least 18 years of age, had a DSM-IV diagnosis of cocaine dependence with at least one po........

The Companion Animal Science Story of the Year?

by CAPB in Companion Animal Psychology Blog

Dogs love learning. Eureka!Photo: Anna Tyurina / ShutterstockScience Borealis challenged Canadian science bloggers to write about the most important science news of the year in their field. It’s incredibly tough to choose one single study. Every week we cover fascinating research about people’s relationships with their pets, and every one of those studies deserves to be chosen. But there was one paper that really captured our readers’ imagination. It’s one of our most shared storie........ Read more »

Christmas Trees Have Trouble Seeing The Light

by Mark Lasbury in As Many Exceptions As Rules

Evergreens maintain chlorophyll all year round so that they can carryout photosynthesis in the winter and be symbols of enduring life for Christmas. No… not really. Sunlight in the winter can actually kill evergreens. You won’t believe the lengths to which they must go in order to avoid photodamage caused by light harvesting by chlorophyll in the winter. So why do they stay green?... Read more »

Seeds of change?

by Isabel Torres in Science in the clouds

Plant science is probably one of the least appreciated fields of life sciences, and yet, perhaps no other research area has produced as many technological advances beneficial for society. In an open letterreleased last month, 21 out of the 27 most cited plant scientists in Europe pledged decision makers to back plant research, which they feel is currently threatened by lack of funding and global public and political opposition to genetically modified organisms (GMOs). “In comparison for i........

Reuse, recycle, repurpose …. how evolution makes do

by Humeandroid in The Art of World-Making

One well-known metaphor for the process of biological evolution is ‘tinkering.’ First proposed by François Jacob in 1977 in a now-famous paper in the journal Science, the idea captures two facets of evolution: the fact that new things must be developed from pre-existing things, and the apparent fact that evolution does not proceed with guidance. The […]... Read more »

The Bat with the Identity Crisis

by Andrew Harrington in Denise O'Meara

There is a misfortunate bat species that is going through a bit of an identity crisis at the moment. This poor creature is Natterer’s bat, or Myotis nattereri to give it its formal name (named after the distinguished 19th Century Austrian naturalist Johann Natterer, not because it makes a lot of noise, as I have sometimes been asked). Natterer’s bat is distributed across Europe and north-west Africa, and is mainly considered to be a woodland species- in other words, it has specialised in hun........ Read more »

How to Look for Squirrels

by Denise O'Meara in Denise O'Meara

The Eurasian red squirrel is, in my opinion at least, one of the cutest additions to the Irish countryside. The little ear tufts of the red squirrel help differentiate it from the invasive grey squirrel, the North American competitor of the red squirrel introduced here about 100 years ago. Other features include the size difference, as the grey squirrel is quite a bit larger. You might think that it should be relatively easy to differentiate the species by colour, but colourations can vary consi........ Read more »
