Spanking in the USA: A sad state of affairs and why spanking is never ok.

by Nestor Lopez-Duran PhD in Child-Psych

MONDAY BRIEFS: Quick mussing on child related research. Editor’s note: Monday’s briefs are usually brief posts, but the topic today resulted in a longer than usual philosophical discussion of corporal punishment. The most recent issue of the journal of the American Academy of Pediatrics included a report on the use of physical violence as a form of discipline [...]... Read more »

News about the Integrated Microbial Genomes (IMG) resource

by Jennifer in OpenHelix

I’ve got a few news items regarding IMG, or Integrated Microbial Genomes, from the DOE Joint Genome Institute. The first item is that their Sept 2010 release occurred this week. IMG is now on version 3.2, has updated features and a bunch of new/revised genomes. I’ve begun updating our tutorial & will let you know when that is released. It’s not the craziest level of tool changes that I’ve seen from this group, but dang, they SURE don’t rest on their laurels! The........ Read more »

can language affect blood flow?

by Chris in The Lousy Linguist

Do languages affect blood flow in the brain differently? Apparently, yes! In a recent fMRI study, researchers showed that Cantonese verbs and nouns are processed in (slightly) different parts of the brain than English nouns and verbs in bilinguals. The researchers used a lexical decision task to contrast the processing of English and Cantonese verbs and nouns in the brains of bilingual speakers.Chinese nouns and verbs showed a largely overlapping pattern of cortical activity. In contrast, Englis........ Read more »

Dizziness, Dix-Hallpike and the Epley manoeuvre

by Euan in Dr Euan Lawson| Doctor Writer

This article is a brief review of the evidence surrounding the diagnosis of benign paroxysmal positional vertigo (BPPV) and the use of the Epley manoeuvre to treat BPPV. The process couldn’t be more straightforward – do a Dix-Hallpike test and if this is positive move on to the Epley manoeuvre. Yet, it doesn’t get done. [...]... Read more »

How do miRNAs affect protein production?

by Becky in It Takes 30

A recent paper from the Bartel and Weissman groups (Guo et al. Mammalian microRNAs predominantly act to decrease target mRNA levels, Nature 466 835-40, PMID: 20703300) provides an interesting snapshot of the journey of a field from consensus to controversy to (one day?) consensus again. At issue is the question of how microRNAs — small [...]... Read more »

Correcting Hubble images

by Emma in we are all in the gutter

I’m going to be upfront here: this post is about CCDs and readout electronics. Wait, come back, it’s going to be interesting I promise*. It involves the Hubble Space Telescope. Everyone likes that, don’t they? Many astronomical instruments, including the ones on Hubble, use Charge Coupled Devices or CCDs. These detectors are like containers for [...]... Read more »

Power leads us to dehumanise others

by BPS Research Digest in BPS Research Digest

'How can you not feel sorry about people who have died? I mean you would be inhuman if you didn't think that,' former UK Prime Minister Tony Blair speaking to Andrew Marr on the BBC.Think how terrible you'd feel if a decision you made led to the death of another person. How then does a political leader cope with the burden of making decisions which lead to the deaths of hundreds of thousands? According to a new journal article, they cope through dehumanising those over whom they have power. By t........ Read more »

Memory as a resource

by Janet Kwasniak in Thoughts on thoughts

p { margin-bottom: 0.08in; }
Some people are surprised, even disturbed, by the idea that our vision does not give us an accurate picture of what we look at. For example, the colours we experience are not a measure of the wavelength of the light entering our eyes. But accuracy is not the point of vision; [...]... Read more »

Story of X

by Razib Khan in Gene Expression

A month ago I pointed to a short communication in Nature Genetics which highlighted differences in the patterns of variation between the X chromosome and the autosome. I thought it would be of interest to revisit this, because it’s a relatively short piece with precise and crisp results which we can ruminate upon.
Sometimes there is [...]... Read more »

Fear/Anxiety/Avoidance – and some treatments!

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

I’ve been pondering the post by Neil O’Connell on Body in Mind in which he comments on a paper by Foster, Thomas, Bishop, Dunne and Main (2010) in which he makes the point that “There is a huge emphasis on psychological variables in research and current care for low back pain.

While travelling to our Supercharge Your Science workshop in Cairns and Townsville last week (which, by the way, went off really well and the punters gave us the thumbs up – stay tuned for more Supercharge activities at a university near you…), I stumbled across an article in the Sydney Morning Herald about the state [...]...

Cold start of Life: Ice as a protocellular medium for RNA replication

by Olexandr Isayev in olexandrisayev.com

The hot spot for life on early Earth may have been a very cold place. Tiny pockets and channels that form inside ice can contain and protect replicating molecules, researchers report September 21 in Nature Communications. The paper suggests that life could have sprung from icy slush covering a freshwater lake, rather than a broiling [...]... Read more »

Psycasm - We should be music testing athletes!

I'm a purist, and I don't know why. I see people jogging on the street with their Ipods and it feels like their cheating. I honestly can't explain this irrationality. It might stem from the days when I used to go to the gym and I would be hill-climbing on an ; (read more)

Guest Post - Survival of the fittest?

by Lab Rat in Lab Rat

I'm very excited about this post, which is a guest post from my sister! She's an undergrad doing biochemistry at Bristol University, and she's currently taking a year working in a research laboratory as part of her degree. She's working with Plasmodium at the moment (which is the little protist that causes malaria) but has sent me a bacteria-related post because she knows me, and she knows my blog and who doesn't love bacteria?Post - survival of the fittest?Bacteria have always been very adapta........

FDA: there to protect us

by Science Exploiter in Science Exploits

Yesterday while walking home from the store, I bumped into a neighbor who seemed out of sorts.  Pulling me aside, he told me of numerous health problems which have developed recently, most of which he blames on a new medicine.  I don't doubt his sincerity, but it did raise some questions. For instance: has he imagined the symptoms?  It sounds terrible to suggest such a thing, but when starting a new treatment how many of us have suddenly noticed something which perhaps we never took notice of........

Let's Talk about Sex

by Brian McMichael, M.D. in Pallimed: a Hospice & Palliative Medicine Blog

I thought I would post on what I hope will turn out to be an occasional series on sexuality here on Pallimed. We've covered sexuality some before. A post that leaps to mind is one by Christian in 2007 about the controversy that arose over a case where the staff at the world's first hospice designed specifically for young adults openly deliberated and decided to facilitate a 22-year-old patient's request to have sex before he died.



So, my foray is on an article that came ........ Read more »

Evo-devo of digital reduction in amphibians

by Kele in Kele's Science Blog

Synopsis: Alberch and Gale: “A Developmental Analysis of an Evolutionary Trend: Digital Reduction in Amphibians” (1985). In this paper, the authors looked at different foot morphologies in extant amphibians and performed some experimental embryology with a few of the species. The induced developmental change followed the natural variation found by the authors! Details below! This [...]... Read more »
