The British Medical Journal has been busy overturning medical myths, according to BBC News.  
"Both physicians and non-physicians sometimes believe things about our bodies that just are not true,"
wrote Dr Rachel Vreeman and Dr Aaron Carroll in this august publication.  But the BBC continues:
We've all been told to put a hat on in winter because most heat is lost through the head.

The researchers even found that the US Army Field manual for survival recommends covering your head in cold weather because around 40-45% of body heat is lost through the head.
All the cells in our body have the same set of genes.  The reason that we have arms, legs, heads, etc. is because transcription factors turn genes on and off in the right places at the right time.  This report out of Colorado Springs shows what happens when genes get turned on in the wrong place.  It appears that the poor child in this report was suffering from a teratoma:  an inappropriately placed but otherwise normal-looking  growth of a body structure in the form of a tumor.  Fortunately, the child is alive and hopefully will recover fully.
Two articles addressing blogging and science have appeared recently in Trends in Ecology and Evolution and in PLoS Biology.
The astronomy/physics sector of the internets is all abuzz about Dark Energy.

It was originally thought that gravity would slow the expansion of the universe as huge astronomical bodies become attracted to each other and pull together like Sumo wrestlers trying to share a waterbed.  That has not happened.  Instead, the universe is expanding, and doing so at an increasing rate.  Dark Energy is the general repulsive force that is kicking gravity's butt and driving the expansion of the universe.
Can science journalism get any more embarrassingly bad?

"Real-time gene monitoring developed" says a headline over at The piece starts off with an insane hook that makes no sense whatsoever:
With GeneVision, military commanders could compare gene expression in victorious and defeated troops. Retailers could track genes related to craving as shoppers moved about a store. "The Bachelor" would enjoy yet one more secret advantage over his love-struck dates.
Bluetooth Laser Virtual Keyboard

This device projects a laser keyboard onto any flat surface.  It even makes clicking sounds when you type.  Apparently it works with most Bluetooth enabled devices.  Practical?  Eh, who knows.  Cool? Oh yeah.
I can relate to Olivia Judson's experience with the digitization of science journals:

On the good side, instead of hauling dusty volumes off shelves and standing over the photocopier, I sit comfortably in my office, downloading papers from journal Web sites.

On the bad side, this has produced informational bedlam.

The journal articles arrive with file names like 456330a.pdf or sd-article121.pdf. Keeping track of what these are, what I have, where I’ve put them, which other papers are related to them — hopeless...

Ben Casnocha asks what I mean by appreciative thinking.

A good question, since I invented the phrase. To learn appreciative thinking is to learn to appreciate, to learn to see the value of things. More or less the opposite of critical thinking.

That I had to make up a phrase shows the problem. I have complained many times about an overemphasis on critical thinking at universities.   Sometimes I’d say, “Have you ever heard the term appreciative thinking?  No?   How many times have you heard the term critical thinking?”

When it comes to scientific papers, to teach appreciative thinking means to help students see such aspects of a paper as:

Ivory towers are replacing smoke stacks in Alabama and all over the US.

This can be a good thing, but there is a core problem:

Until relatively recently, most universities and the cities surrounding them went about their business without taking full stock of what each meant to the other. Many local and state government leaders, notes Temple University political scientist Carolyn Adams, "don't see these institutions as having an economic development function much beyond employment and land development." For their part, hospitals and academic institutions aren't accustomed to thinking of themselves as de facto economic bigwigs or pondering the responsibilities that go along with that status; for many, the prevailing attitude toward the communities that host them has essentially been, "You should just thank your lucky stars we're here."
If you're comfortably entrenched at the University of Maryland and not worried about a mortgage like Michigan autoworkers, you can understand why it's important that there will be debate about the actual numbers of jobs at risk.    A new projection by the University of Maryland's Inforum economic research unit says peak job losses from automobile bankruptcies would be half of the 3 million commonly stated in the media. 

And if the University of Maryland is wrong, oh well, no one will lose their job.  

The three million job-loss figure comes from two separate studies, which are technically correct  but based on implausible assumptions, says University of Maryland economist Jeffrey Werling, Inforum executive director.
