"Anxiety, depression and fatigue are common complaints in patients with untreated celiac disease and contribute to lower quality of life."That was one of the conclusions reached in the paper by Fabiana Zingone and colleagues  (open-access available here) following their review of the research literature "on psychological morbidity of celiac disease." Celiac (coeliac) disease (CD), by the way, is the autoimmune condition classically treated via the use of a gluten-free diet (GFD). Readers........ Read more »

Aitana Lertxundi has conducted her research work within the framework of the INma (Childhood and Environment) programme led by Jesús Ibarluzea of the Department of Health of the Government of the Basque Autonomous Community (region). The aim is to assess how exposure to environmental pollution during pregnancy affects health and also to examine the role of diet in physical and neurobehavioural development in infancy. The study focusses on the repercussions on motor and mental development during........ Read more »

New research shows that infections can impair your cognitive ability measured on an IQ scale. The study is the largest of its kind to date, and it shows a clear correlation between infection levels and impaired cognition. Anyone can suffer from an infection, for example in their stomach, urinary tract or skin. However, a new Danish study shows that a patient’s distress does not necessarily end once the infection has been treated.... Read more »

Spatial Ecosystem models can be useful but need to be validated with data. Our study validates for the first time the spatial version of the commonly used Ecopath with Ecosim ecosystem modelling suite. We find that spatial distribution of fish species is well predicted by the model, but fishing effort distribution is not.

International Clinical Trial day (May 20th) celebrates the medical advances as a result of clinical trials. Clinical trials are essential to ensure drug safety and efficacy, and the recent increase in the development of orphan drugs has led to an increase in rare disease clinical trials. The nature of rare diseases creates specific challenges for clinical trial design and patient recruitment.... Read more »

"These results provide evidence that gains from early intensive intervention are maintained 2 years later.

Many years ago, a guy called Michael Persinger achieved a certain amount of fame with a claim that stimulating the right part of the brain with a magnetic field could give people a religious experience.

While fusion might still be a far off dream, a new discovery may help bring that dream closer to reality. Scientists have discovered a phenomenon that helps them to improve fusion plasmas, a finding that could quicken the development of large scale fusion energy. The scientists found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically....

We’re using far too many antibiotics. That has been the cry from the FDA and the WHO for the last several years as more and more antibiotic-resistant strains have been found after they had colonized or killed patients. Of course these bacteria aren’t completely immune to our arsenals of drugs, they’re just harder to kill with certain antibiotics or require different ones, but a rather small, yet unsettling number, have required doctors to use every last antibacterial weapon [...] ......

The squash bug mating orgies that biologist Christine Miller began noticing in gardens around Gainesville were nothing unusual. Dozens of insects were crowded together, the petite males along with the bulkier females, to search for partners. The unusual thing was that some males were copulating with females of the wrong species—apparently, they found them irresistible.

The helpful folks at NCBI have been ramping up their outreach. I’ve been watching a lot of their webinars, and they are trying different styles.

Even indoor pets help us get to know other people, according to new research in four cities in the US and Australia.It’s easy to see how people who regularly walk their dog can get to know others. They might strike up friendly conversations about dogs, or learn to avoid certain people because of the way their off-leash dog charges up with unwanted “friendly” advances. It’s less obvious for people who don’t walk their dogs, or who have pets that are always indoors. But a new study by re........ Read more »

A provocative paper says that neuroscientists who research mental health problems ought to listen to the views of people who have experienced those conditions.

A current theory is that humans (and other animals) perceive symmetry as beauty and is desirable in a mate. Symmetric bodies and faces are correlated with strength, overall health, facial beauty, and dancing ability, but also with extramarital affairs. On the other hand, on butterfly thrives on ugliness. Asymmetric wings actually help males fly better during sexual competitions and gives them a reproductive advantage.... Read more »
