Trade balances in microbial communities

by Becky in It Takes 30

So this week seems to be turning out to be cooperation week.  We talked about cooperative behavior of the proteins that make up the cytoskeleton on Monday, cooperation in breeding behavior in birds on Wednesday, and now it’s time to talk about cooperative behavior in bacteria.  If only I’d planned it in advance.  Ah well; [...]...

A Tale of Two Genes

by Neuroskeptic in Neuroskeptic

An unusually gripping genetics paper from Biological Psychiatry: Pagnamenta et al.The authors discuss a family where two out of the three children were diagnosed with autism. In 2009, they detected a previously unknown copy number variant mutation in the two affected brothers: a 594 kb deletion knocking out two genes, called DOCK4 and IMMP2L.Yet this mutation was also carried by their non-autistic mother and sister, suggesting that it wasn't responsible for the autism. The mother's side of the f........ Read more »

Paucis Verbis card: When murmurs need echo evaluation

by Michelle Lin in Academic Life In Emergency Medicine

Have you been in a situation where you are the first to detect a cardiac murmur in a patient? If you are hearing it in a busy, loud Emergency Department, I find that it's at least a grade III. Should you order an echocardiogram for further outpatient evaluation? It depends on the grade and characteristic of the murmur, in addition to the patient's symptoms. For instance, all diastolic murmurs require an echo. There is a useful ACC/AHA algorithm which helps you decide.Thanks to Amy Kinard, an Eme........ Read more »

Cattle’s great adventure

by Jeremy in Agricultural Biodiversity Weblog

Evolutionary Anthropology has a nice paper summarizing the history of domestic cattle, based on the latest molecular marker data. Unusually, the authors at least attempt a flowing account of the origin and spread of a domesticated species, and even more unusually actually achieve it in places. Alas, the details of haplogroups and mtDNA vs Y-chromosome [...]... Read more »

Tolkien’s The New Darwin? Gollum and Cavefish Tell All

by Michael Gutbrod in A Scientific Nature

Reading the following passage might lead you to exclaim: “What an incredible storyteller J.R.R. Tolkien was!” or more likely, “What a visionary evolutionary biologist J.R.R. Tolkien was!” depending on how you interpret it of course. “He was Gollum—as dark as darkness, except for two big round pale eyes in his thin face.  He had a [...]... Read more »

Too Good To Be True

by Journal Watch Online in Journal Watch Online

It was a rare bit of good news. India’s Forest Ministry recently announced that the nation’s forests had expanded by nearly 5% over the last decade – an impressive gain in a country that had lost 80% of its native trees. But three researchers are now challenging that survey, saying it masked continuing forest losses […] Read More »... Read more »

Mechanism of Fatty Acids Anti Inflammatory Effects – Explained?

by Michael Ash in Nutri-Link Ltd - Clinical Education

Most Nutritional Therapists are comfortable in the concept and application of concentrated essential fatty acids especially fish oils as a means of altering abnormal inflammatory pathways in the body. Some EFA’s are perceived to be anti-inflammatory and others pro-inflammatory. Whilst the simplistic dichotomy of interpretation (Omega 3 Anti/Omega 6 Pro) has kept many a student [...]...

A genetic cause of rapid degeneration in some Alzheimer's patients

by Greg Laden in Greg Laden's Blog

A new study identifies a likely cause of rapid degeneration in some Alzheimer's patients. The results of this study may lead to improved treatment.

But first, let's look at the method used in this study, because that may be almost as important as a development. And for this, we will use a sports analogy. Read the rest of this post... | Read the comments on this post...... Read more »

The tarnished golden rule

by Tom Rees in Epiphenom

Subliminal priming is a cool psychological trick that can change the way you think or the things you do without you even being aware of it. So, for example, you do a word puzzle that includes religious words, and chances are you'll behave more honestly later.

Which brings us to the Golden Rule. This is one of those basic components of human morality that pops up in pretty much every culture - the British Humanist Society even produces a poster with 20 different versions from around the world. T........ Read more »

Why Are Cell Phone Conversations So Distracting?

by John M Grohol PsyD in World of Psychology - Psych Central


We’ve all been there — sitting in a public place, and feeling like that person over there, talking on their cell phone, is so annoying. Why are they so annoying? What makes a cell phone conversation that you overhear so distracting?
Four researchers, led by Lauren Emberson (2010) from Cornell University, set to find out.
Previous research has shown that we don’t seem to be as distracted when listening to a full dialogue between two people as when we are listening to a “h........ Read more »

Drugging the cell's best friend

by The Curious Wavefunction in The Curious Wavefunction

The tumor suppressor p53 is one of the cell’s very best friends. Just how good a friend it is becomes apparent when, just like in other relationships, this particular relationship turns sour. p53 is the “master guardian angel” of the genome and constitutes the most frequent genetic alteration in cancer. More than 50% of human tumors contain a mutation in the p53 gene. With this kind of glowing track record, p53 would be a prime target for drugs.It turns out that discovering drugs for p53 i........

A Blue Shirt and AA Batteries: Sorting Through The Mess

Storage room, garage, attic, boxes, under the bed, dorm room... Whatever we choose to call it it, we all have our secret stashes of mess. Imagine the last time you were forced to confront your secret mess pile (if you are anything like me, this is still in short-term memory) to find your blue shirt amongst the heaps of cell phone chargers, clothes, and other notebooks. A few days later, you have to re-confront the mass to find a few AA batteries. Do you have any chance?... Read more »

by Ultimo167 in Strong Silent Types

Anderson (2010) discovers that cheating men crave ‘emotional monogamy’ with their partners and to have their physical desires fulfilled through multiple, additional sexual contacts. Many such men claim to love their partners even more because they cheat on them.
