The misuse of terms ‘homology’ in bioinformatics community

by Abhishek Tiwari in Fisheye Perspective

In a recent letter to the editor of journal Bioinformatics Marabotti and Facchiano have raised the concern over the misuse of term ‘homology’ in peer-reviwed bioinformatics papers. This issues is not new for the scientific community at all, in fact severity of the issue was first recognized in 1987 when a letter to the Editor [...]

trouble with biomarkers and press releases

by Tal Yarkoni in citation needed

The latest issue of the Journal of Neuroscience contains an interesting article by Ecker et al in which the authors attempted to classify people with autism spectrum disorder (ASD) and health controls based on their brain anatomy, and report achieving “a sensitivity and specificity of up to 90% and 80%, respectively.” Before unpacking what that [...]...

by Rift in Psycasm

As I’m getting on in my study I’ve found that people (outside of uni) treat me as something of an expert on all things ‘brain’. I don’t push this image because, frankly, I’m not an expert in anything. Though most of the time I can find some element of their question I can answer, however [...]... Read more »

How well do we really communicate?

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

I’m pretty sure most clinicians want to believe that they treat people with equal respect, that they listen carefully and respond with empathy when a person has concerns about their health. At the same time I’ve listened to many people with chronic pain describe how they’ve had trouble feeling heard, how they can feel like … Read more... Read more »

Explaining temporal resolution with water-works of the visual system

by Alex Holcombe in ceptional

Most people are confused about temporal resolution. That includes my students, and even BBC science programmes. So I created this diagram to communicate the basic concept, with the example of human visual processing, using a water-works metaphor. Why water-works? I’m trying to explain an unfamiliar concept in terms that everyone can understand intuitively. By using [...]... Read more »

Airplane Headache

by The Neurocritic in The Neurocritic

Cartoon Reenactment of JetBlue Flight Attendant’s Dramatic ExitNo, the term "airplane headache" does not refer to disgruntled JetBlue flight attendant Steven Slater (or to being a passenger on that flight). Instead, it refers to a recently characterized type of headache that occurs during take-off and landing (Atkonson & Lee, 2004). The pain appears to be unique to plane travel and not associated with other conditions. Neurological exam and brain imaging results in all published cases (n=........ Read more »

Is Your Brain Autistic?

by Neuroskeptic in Neuroskeptic

There's been a lot of buzz and some scepticism about theNew brain scan to diagnose autismHere's a quick overview. Autism is believed to be a disorder of brain development. If so, it should be possible to diagnose it based on a brain scan. Unfortunately, it's not. You can't tell, from a scan, whether someone has autism or not. Not even if you're a world expert.There are reports of various differences between autistic and non-autistic brains - a bit smaller here, a bit bigger there - but there's a........ Read more »

The complexity of sinuous channel deposits in three dimensions

by Zoltan Sylvester in Hindered Settling

The beauty of the shapes and patterns created by meandering rivers has long attracted the attention of many geomorphologists, civil engineers, and sedimentologists. Unless they are fairly steep or have highly stable and unerodible banks, rivers do not like to follow a straight course and tend to develop a sinuous plan-view pattern. The description and mathematical modeling of these curves is a fascinating subject, but that is not what I want to talk about here and now. It is hard enough to under........ Read more »

Predicting catastrophic health events - noninvasively and short term

by Aurametrix team in Health Technologies

"I've just picked up a fault in the AE35 unit. It's going to go 100% failure in 72 hours". These were famous words of the almighty computer HAL in "2001: A Space Odyssey". Few of us believe too much in software forecasts - be it weather, earthquakes or computer hard disk failures. Yet, we all know that sometimes it works. And such systems are very valuable, assuming they continuously improve. ... Read more »

Wolf Spider Leg Regeneration Impairs Foraging

Wrinn & Uetz studied how leg loss and regeneration affected the condition, growth and development time of the wolf spider, Schizocosa ocreata (Lycosidae, photo at left). Spiders may amputate their legs as a defense strategy, but it’s not clear what trade-offs exist. For instance, if a spider [...]... Read more »

Mercury Rising

Although Ethiopia has shown an impressive economic growth over the last seven years, one-third of its population remains poor. To achieve the MDG, an annual economic growth of 7 % is needed, and in the last years the growth has exceeded this critical figure.
