The final (?) word on those handaxes from Crete

by Julien Riel-Salvatore in A Very Remote Period Indeed

While everybody was busy talking about unexpectedly old cutmarks and other Pleistocene goings-on last week, the paper by Strasser et al. (2010) describing the discovery of quartz handaxe assemblages on Crete quietly came out in Hesperia. This is a topic that was discussed at length on this blog, in several posts that generated a large amount of comments a few months back. The sticking point of ... Read more »

What is being taught in the operating room?

by Dr Shock in Dr Shock MD PhD


You can think of a lot such as technical procedures or washing your hands. For residents it’s obvious. Mostly learning the technical procedure of an operation. During long operations I used to count the number of stitches. Once during a vascular operation the chief surgeon out of the blue asked what vessel it was they’re [...]

Ultracold atoms as model systems

by Joerg Heber in All That Matters

One of the fundamental concepts of quantum mechanics is that objects can be described as waves, whether they are electrons, atoms, light, anything really, even your cat (or that of Erwin Schrödinger). And of course, if the equations that describe their wavefunctions are identical, objects will behave in the same way. Even if they are fundamentally different physical entities.

Two papers published this week highlight just how far this analogy can go. In one study a gas of ultracold atoms beha........ Read more »

More poop Mommy; I'm hungry!

by The Science Pundit in The Science Pundit

A few years ago, a cousin of mine told me the story of the time she was at a public swimming pool (in Utah, I believe) when her infant son demanded to be fed. She did what came naturally: she began to breastfeed her son. This act didn't go over very well with at least one of the pool's patrons, who came over to my cousin and sneered "That's disgusting! I have young children and they don't need to see that!" My cousin mused on how curious it was that this lady wasn't bothered by her children ........ Read more »

Making autism research history: The Pre-school Autism Communication Trial

by Michelle Dawson in The Autism Crisis

Some months ago, Jonathan Green and his colleagues simultaneously published (in the Lancet) and presented (at IMFAR 2010) their multi-site RCT of an early autism intervention. In conducting and reporting the Pre-school Autism Communication Trial, they have made autism research history. They have done so simply by applying to autistics scientific standards that are well-established in non-autism non-ABA areas. The upshot is an autism early intervention trial whose results are worth serious consid........ Read more »

The ecosystems within us

by Aaron Berdanier in Biological Posteriors

In the guts of each of us there are trillions of microbes. They provide us with "enhanced metabolic capabilities, protection against pathogens, education of the immune system, and modulation of gastrointestinal development" (De Filippo et al. 2010). The diversity of these organisms can play a role in the future development of disease. But, what makes our guts so diverse? As De Filippo et al. (2010) report, one main factor appears to be diet....

Melatonin and Sleep Disorders in Children

I previously posted a study that found melatonin to be an effective treatment for insomnia among children with autism.  This post has been accessed via Google search more than any other Brain Posts.  It is apparent that many people are interested in the potential role of melatonin in treating sleep problems in children.There have been several research and clinical guideline manuscripts that address this issue.  A review of sleep disorders in children was published in Clinical Evid........

Snowball Earth no problem for sponges

Could The Planck Satellite Discover A New Species Of Neutrino?

by Joseph Smidt in The Eternal Universe

It has been known for some time that the WMAP data is more consistant with the existence of four neutrino species than three. Nevertheless, most cosmologists shrug this off as three is by no means ruled out. However, Hamann et al. 2010 demonstrate that such a dismissal may be a mistake.

It turns out, when WMAP 7 year data is combined with Sloan data, the three neutrino species model is ruled

Vitamin D

Vitamin D is a fascinating molecule with a fascinating story.  Historically, “vitamins” were defined as chemicals that humans required from their environment that were “vital” to human health.  These chemicals were needed only in very small amounts to prevent disease; an absence of a particular vitamin in the diet led to a specific deficiency disease: [...]...

Can Energy Sector Workers Serve as Influential Public Ambassadors?

by Matthew C. Nisbet in Age of Engagement

Earlier today, in response to Sheril Kirshenbaum’s query at Discover’s Intersection blog, I spotlighted the key influence of opinion-leaders on energy related behavior.  As a follow up, let’s take a look at a new study out this month, co-authored by John Besley, an assistant professor of Communication at the University of South Carolina (and a friend of mine from our doctoral studies together at Cornell.)
In the study appearing at the International Journal of Hydrogen Ener........ Read more »
