Echoes of the Past

by teofilo in Gambler's House

There’s a spot near the west end of the Pueblo Bonito parking lot, close to the spot where guided tours begin, where you can yell something in the direction of the canyon wall and hear a very clear echo back.  Some of the tour guides at Chaco regularly demonstrate this impressive effect when beginning their [...]...

Is the Clinical Significance Criterion Significant?

by Neuropsych15 in The MacGuffin

The draft version of DSM-V: Revenge of the Fallen has been online for a few weeks (1) and much has already been written about it (1, 2, 3, 4). Much focus has been on what is "new" and what is "gone." One feature that is shared by the majority of DSM diagnoses, the "clinical significance" criterion, might be on its way out. Typically this criterion reads "The symptoms cause clinically significant distress or impairment in social, occupational, or other........

A personal god boosts the placebo effect

by Tom Rees in Epiphenom

The placebo effect is that spooky phenomenon that can cure people simply by convincing them they're getting real medicine (whereas they in fact are just taking a sugar pill). Although it's been reported in all sorts of areas of medicine, it's particularly potent for treating things like irritable bowel syndrome, pain, and depression.In fact, a recent analysis found that most of the effect of antidepressant medicine in people with depression was in fact due to the placebo effect (but the effect........

Social Cognition in Dogs, or How did Fido get so smart?

by Jason Goldman in The Thoughtful Animal


Figure 1: Dogs are pretty intelligent.
Domesticated dogs seem to have an uncanny ability to understand human communicative gestures. If you point to something the dog zeroes in on the object or location you’re pointing to (whether it’s a toy, or food, or to get his in-need-of-a-bath butt off your damn bed and back onto his [...]...

The power of prediction reduces activation in the primary visual cortex

by William Lu in The Quantum Lobe Chronicles

Prediction is an invaluable skill for navigating through complex environments. Somehow the brain generates predictions about perceptual inputs it's likely to receive using contextual information from recent memory. Statistical regularities are learned (e.g. movement and attack patterns of Mega Man bosses) and lead to less activation in corresponding brain areas. The brain is truly a miserly organ. "Why put in more work than I have to when I know what's gonna happen next", says the brain. Alink a........ Read more »

Research demonstrates that marine protected areas aid coral reefs

by Katie Kline in EcoTone

Research has shown that marine protected areas (MPAs)—areas where fishing and other potentially destructive activities are regulated—are benefitting, not just the fish habitats they are known to aid, but nearby coral reefs as well. MPAs may benefit corals by restoring reef-based food webs and protecting damage from anchors and nutrient runoff.... Read more »

It's What You Learn, Not What You Think

by Cole Bitting in Fable


Some symptoms of OCD might be describable as pathological doubt, for instance, that one’s hands are clean or that the doors are locked. A review of OCD treatments states, “pathological doubt is one of the central manifestations of this illness. The person goes to the door, shuts it, locks it, feels that it is locked, knows that it is locked, turns around, and walks away. All of a sudden, he or she feels that it is absolutely necessary to go back and check. It appears clinically that the m........ Read more »

Invasive species runs out of evolutionary "steam" as it invades

by Jeremy Yoder in Denim and Tweed

For invasive plants, flowering time is a trait that may often be under selection during colonization—when a plant flowers determines its climatic tolerances, its vulnerability to herbivores, and its compatibility with the local pollinator community. In a study just released online at Proceedings of the Royal Society B, Colautti and coauthors examined the evolution of this trait in a plant that has swept across eastern North America since its introduction from Europe: purple loosestrife, and fo........

Can biomanipulation of the sea rescue a collapsed fishery?

by Rob Goldstein in Conservation Maven

The cod stock in the Baltic Sea collapsed in the 1990s because of overfishing and climate change, and this once-valuable fishery has not yet recovered. Could intensified harvesting of sprat—a small fish that eats cod eggs and competes with young cod for planktonic food—be the solution to restore cod, as some people suggest?  ... Read more »

How Your Brain Groups Words

by Shaheen Lakhan in Brain Blogger

When you say or hear a concrete noun, such as “apple”, what happens in your mind? Even without seeing a physical apple in front of you, your brain is drawing up an image of an apple, maybe the last one you ate or saw in the stores or on TV. A team of researchers at [...]... Read more »

How Soon Should You Have Surgery After a Multiple Ligament Knee Injury?

Today’s post is another research update by Dan Lorenz on the effect of surgical timing in multiple ligament knee injuries.  There are pros and cons to both acute and chronic reconstruction.  My experience has always been to be about the middle of the road, get them early but let them settle down a bit first, then get rehab going...

Did spirochetes kill off the Indians in Massachusetts before the Mayflower landed?

by Microbe Fan in Spirochetes Unwound

The coast of present-day Massachusetts was inhabited by several Native American tribes in the early 17th century.  Fishermen, traders, and explorers from the Old World encountered the Indians during their occasional travel through the area.  However by the time the Mayflower landed in Plymouth in 1620 to establish a colony, a mysterious epidemic had ravaged coastal New England, killing up to 90% of the indigenous population during the years 1616 through 1619.  Experts have yet to ........

One of the many tools we use in our team to manage the development of ChEBI software is an automated build tool called Apache Maven.

Getting up to speed with sound localisation

by kubke in Building Blogs of Science

Funny how we are really good, for the most part, at knowing where sounds are coming from. And it is funny since the ear provides the brain with no direct information about the actual relationship in space of different sound sources. Instead, the brain makes use of what happens to the sound as it reaches [...]... Read more »
