This (Long) Week in the Universe: September 16th – September 27th

by S.C. Kavassalis in The Language of Bad Physics

I know, I know, I switched back to writing these on Mondays again without telling anyone.  It turns out, Wednesdays were a terrible choice of day for me. I swear I asked someone to fill in for me last week…
...but I guess she wasn't all that interested in the job.

Innate Immune Memory in Mosquitoes: The Latest Buzz in the Fight against Malaria

by Kelly Grooms in Promega Connections

For many of us mosquitoes are an itchy aggravation. They come in the evenings in the warmer months. They disrupt hikes, camping trips and picnics, leaving behind itching reminders that have us reaching for antihistamines and no-itch creams. For people in some areas of the world however, mosquitoes are more than just a pest with [...]... Read more »

How to put the quantum into silicon computers

by Joerg Heber in All That Matters

Quantum computers are so highly sought after because they can solve complex mathematical problems and parallel computer operations such as code breaking really fast. Attempts to build quantum computers come in many flavours and use different kinds of quantum states, ranging from trapped atoms, superconductors to semiconductors such as gallium arsenide or diamond. The approach [...]... Read more »

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.

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 »

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

by Olexandr Isayev in

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)
