Genetic counselling and schizophrenia tests

by Wellcome Trust in Wellcome Trust Blog

Genetic testing has many ethical implications. These can be particularly sensitive when it comes to psychiatric conditions such as schizophrenia that are open to misconception and stigmatisation. Although knowledge of one’s risk of developing a disorder can lead to positive changes in behaviour, and allow for early intervention, these come mixed with disadvantages, including feelings [...]...

When a client confesses to murder

by BPS Research Digest in BPS Research Digest

Dr. Jennifer Melfi: What line of work are you in?
Tony Soprano: Waste management consultant.Client confidentiality in psychotherapy only goes so far. If a client threatens the therapist, another person, or themselves, and the threat is perceived as serious, then most jurisdictions (including the BPS ethics code) recognise this as a valid reason to breach the client's privacy and go to the authorities. But what about the situation in which the client confesses to a past violent act for which........ Read more »

How to read a genome

by Becky in It Takes 30

What makes you the unique human being you are?  Partly it’s nurture — what your mother ate while she was pregnant with you, whether she smoked, how much you exercise, which drugs you take — and partly it’s nature.  The part that’s nature is sometimes clearcut — if your biological father and mother both had [...]...

Kayenta Warfare

by teofilo in Gambler's House

I’ve written quite a bit here about warfare in the prehistoric Southwest, but I’ve only said a little about one of the areas where it has been most carefully documented and studied: the Kayenta area of northeastern Arizona.  This is partly because this area seems to have had very little contact with or influence from [...]...

Do Doctors Really Have Bad Handwriting?

by Maria P. in noustuff

Trying to kill time and not my neighbour who enjoys listening to loud music after midnight, I found myself wondering why do most GPs have bad handwriting! Or is it a myth?

When Crossing or Responding to Your Opposing Expert Witness, Look for the L.I.E. (Large Internal Error)

by Persuasion Strategies in Persuasive Litigator

By: Dr. Ken Broda-Bahm - When the case comes down to 'expert versus expert,' one important question is, what makes jurors believe one expert witness over another? Applying the rational model of law, we would like to think that jurors would evaluate the credentials, the methodology, and the strength of the conclusions offered, and compare the competing experts based upon the appropriate standards of the field. That would be rational, but alas, not really typical in the courtroom. Instead, jurors ........ Read more »

Brain Stimulation for Parkinson Disease: Expert Opinion

by William Yates, M.D. in Brain Posts

Parkinson disease is a chronic progressive disease with significant impairment and distress.  A host of pharmacological options are available. Unfortunately, drug treatment often is only partially successful in reducing symptoms and can produce problematic adverse events.  Deep brain stimulation (DBS) has emerged as a potential therapeutic option for those with severe Parkinson disease.  DBS involves a neurosurgical procedure that places an electrode or electrodes into the brain w........

Are cows magnetic sensors? Re-examining northern alignment

by Zen Faulkes in NeuroDojo

A couple of years ago, a paper by Begall and colleagues made a big splash by claiming that cows could detect, and align to, earth’s magnetic field. This report took on a life of its own. I heard it within the last week on one of the science podcasts I listen (though I can’t remember which one).

This paper got attention not only because this was an unusual claim, but for the way that they determined this. Instead of generating their own data, they looked at pictures of cows in Google Earth.

Can we feed the world and save its forests?

by Tim De Chant in Per Square Mile

Nine billion is the number that will define the 21st century. That’s the number of people expected to live on this planet by 2045. But 9 billion mouths are a lot to feed, and each of them will hopefully have more than enough to eat. Achieving both goals—feeding 9 billion and feeding them properly—will be a [...]... Read more »

Abort! Abort!

by Vasili Hauryliuk in stringent response

Sometimes things go so wrong that it is just easier to start all over again. Bacteria have these situations too - it's not just us, humans! - and the central dogma of molecular biology (DNA replication, transcription and translation) is no exception.In essence all the three steps of the central dogma share the very same basic topology: there is a message that gets read, there is a tool that reads it and there is a product. It looks like so:Say, in the case of translation mRNA (the mess........ Read more »

Light bending to the extreme

by Joerg Heber in All That Matters

How does a lens work? Well, as the light arrives at the lens it gets bent towards the focal point of the lens. The denser the lens material is in comparison to the surrounding air, the more it is deflected. The materials property that quantifies this effect is the refractive index. For lenses, the general [...]... Read more »

The most powerful substance known to rat.
