Decameter type III bursts with changing frequency drift-rate signs by V. Melnik et al.*

by CESRA in Solar Radio Science

We discuss properties of type III bursts that change the sign of their drift rate from negative to positive and vice versa. Moreover, these bursts may change the sign of their drift rates more than once. These particular type III bursts were observed simultaneously by the radio telescopes UTR-2, URAN-2, [...]...

Chronic fatigue syndrome and the detrimental application of the 'biopsychosocial model'

by Paul Whiteley in Questioning Answers

'The times they are a changin'' said a Nobel prize winner and that's also a sentiment that seems true when it comes to chronic fatigue syndrome / myalgic encephalomyeltis (CFS/ME) too (see here for example).Anyone who has followed the tos-and-fros of the PACE trial - the one that suggested that CBT (cognitive behavioural therapy) and GET (graded exercise therapy) might provide some significant relief of symptoms associated with CFS/ME - will probably have heard the ........

Cold medicine could stop cancer spread

by Dr. Jekyll in Lunatic Laboratories

Bladder cancer is the seventh most common cancer in males worldwide. Every year, about 20,000 people in Japan are diagnosed with bladder cancer, of whom around 8,000--mostly men--succumb to the disease. Bladder cancers can be grouped into two types: non-muscle-invasive cancers, which have a five-year survival rate of 90 percent, and muscle-invasive cancers, which have poor prognoses.

Maternal obesity and offspring autism meta-analysed (again)

by Paul Whiteley in Questioning Answers

Meta-analyses eh? You spend ages waiting for one and two come along in quick succession. Well today I'm posting about yet another meta-analysis of the peer-reviewed scientific literature suggesting that "excessive maternal BMI [body mass index] is associated with an increased ASD [autism spectrum disorder] risk in offspring." [1]The review by Ying Wang et al follows hot on the heels of the meta-analysis by Li and colleagues [2] (see here for my take) but further looked a........ Read more »

Call me: female zebra finches prefer their mate’s call

by Emily Makowski in Sextraordinary!

Social interactions are highly sought-after and rewarding in many animals... Even when social interactions involve only one of our senses, they are still rewarding. For example, we like looking at photos of our friends on Facebook, or hearing the voice of a faraway relative via telephone. It’s the same with other animals; not only is socialization rewarding and can be used as an incentive for learning, but just the sights, sounds, and even smells of others are also rewarding. Hernandez et ........ Read more »

Female brains change in sync with hormones

by Dr. Jekyll in Lunatic Laboratories

Although it has already been known for some time that the brain does not remain rigid in its structure even in adulthood, scientists have recently made a surprising discovery. The brain is not only able to adapt to changing conditions in long-term processes, but it can do this every month.

Untangling a cause of memory loss in neurodegenerative diseases

by Dr. Jekyll in Lunatic Laboratories

Tauopathies are a group of neurodegenerative disorders, including Alzheimer's disease that are characterized by the deposition of aggregates of the tau protein inside brain cells. A new study reveals that the cutting of tau by an enzyme called caspase-2 may play a critical role in the disordered brain circuit function that occurs in these diseases.

Know your brain: Suprachiasmatic nucleus

by neurosci in Neuroscientifically Challenged

Where is the suprachiasmatic nucleus?











the suprachiasmatic nucleus is represented by a small green area within the hypothalamus (indicated by red arrow).







The suprachiasmatic nuclei are two small, paired nuclei that are found in the hypothalamus. Each suprachiasmatic nucleus only contains approximately 10,000 neurons. The nuclei rest on each side of the third ventricle, just above the optic chiasm. The location provides the rationale for........ Read more »

Atopic dermatitis and the "increased risk of developing ADHD and ASD later in life"

by Paul Whiteley in Questioning Answers

I'm not gonna dwell too much on the findings reported by Lee and colleagues [1] talking about how "toddlers who suffer from AD [atopic dermatitis] at the age younger than 3 years are at a higher risk of developing ADHD [attention-deficit hyperactivity disorder] and ASD [autism spectrum disorder] during later childhood" because science already seems to understand that there may be an important connection between early allergic disease and later offspring behavioural/........

High cholesterol triggers mitochondrial oxidative stress leading to osteoarthritis

High cholesterol might harm more than our cardiovascular systems. New research using animal models suggests that high cholesterol levels trigger mitochondrial oxidative stress on cartilage cells, causing them to die, and ultimately leading to the development of osteoarthritis.

Is it possible to normalize citation metrics?

by SciELO in SciELO in Perspective

Bibliometric indicators represent much more than an indication of the visibility, relevance and impact of an article. A researcher’s entire career profile can be summarized in one or more numerical productivity and impact indicators of his research. However, citation metrics vary considerably according to the area of knowledge, the publication age, the type of document and the coverage of the database where citations were accrued. Is it possible to normalize them? Here we discuss the challenge........ Read more »

Pathways to Substance Use and Abuse

by William Yates, M.D. in Brain Posts

Neuroscience medicine clinicians encounter patients every day who have both a mental and substance use disorder.This co-occurrence, or comorbidity, complicates diagnosis, treatment and outcome.The exact mechanism for this comorbidity issue is unclear.A recent study out of Washington University in St. Louis and King's College London provides some insight into this comorbidity issue.They examined participants in the Study of Addiction: Genetics and Environment (SAGE). These subjects provided genet........ Read more »

Forgetting Earth, forgetting Mars: Dementia, pollution, and space travel

by gdw in FictionalFieldwork

Forgetting Earth Dementia. Few words inspire greater fear in those of us who value (quasi-?) independent thought. The term ‘dementia’ encompasses various brain disorders that all share some scary traits: general decline in cognitive function, decreased ability to speak, and in later stages, being unable to take care of oneself. Unfortunately, as human lifespan increases […]... Read more »

Yet more on potential biomarkers and chronic fatigue syndrome

by Paul Whiteley in Questioning Answers

'Thick and fast' is probably the best way that I can describe the flurry of peer-reviewed scientific papers recently appearing (see here and see here for examples) talking about how chronic fatigue syndrome (CFS) (also linked to the diagnosis of myalgic encephalomyelitis, ME) might have some important biological processes attached to it.Now we can add the findings reported by Federica Ciregia and colleagues [1] (open-access) to the list and their observations that "the identification of bio........
