Neury Thursday: Sleep and the Blood Brain Barrier, with some hesitation

by Allison in Dormivigilia

Researchers found that the permeability of the blood brain barrier is compromised with chronic sleep deprivation. However, the methods section brings these findings into question. Scientists, do your job and make those methods detailed. ... Read more »

Video Tip of the Week: Genome Browser in a Box

by Mary in OpenHelix

We’ve been doing UCSC Genome Browser training workshops for a decade now. We’ve seen all sorts of situations–from places that had terrific bioinformatics and IT support, to places where the attendees had no idea if anyone provided support at their institution. Ironically, sometimes the places with little support were big-name research places where all the […]... Read more »

How Many Dogs is Enough for Canine Science?

by CAPB in Companion Animal Psychology Blog

And does it matter which dogs they are?Photo: Julia Remezova / ShuterstockThe number of dogs that take part in each research study is variable. Often, the sample size is small, because of the difficulty of recruiting dogs and their owners. And while scientists know how many are needed for statistical analysis, there are other things to take into account too.For example, breed may or may not be relevant. If only ten dogs take part in a study and they are all Australian Shepherds, the result........ Read more »

Doing More With Less

by Mark Lasbury in As Many Exceptions As Rules

Animal-like protists are similar to animal cells, but they do many things in their single cell that we have a hard time competing with. New research shows that they may be useful in medicine, as well as lethal in some cases. N. fowleri is a brain eating amoeba, but calcium tests of foraminifera may be helpful in bone grafts and repairing skull fractures.... Read more »

Simple Jury Persuasion: The “not in my town!” effect

by Doug Keene in The Jury Room

A couple of years ago we were working for the Plaintiff on pretrial research for a case against a large national healthcare corporation. The Plaintiff had been injured quite dramatically due to what she alleged was the Defendant’s lack of care (i.e., negligence) in selling her what company executives knew to be a pharmaceutical product […]

You've heard of "Owls" and "Larks", now sleep scientists propose two more chronotypes

by BPS Research Digest in BPS Research Digest

For many years psychologists have divided people into two types based on their sleeping habits. There are Larks who rise early, feel sprightly in the morning, and retire to bed early; and Owls, who do the opposite, preferring to get up late and who come alive in the evening.Have you ever thought that you don't fit either pattern; that you're neither a morning nor evening person? Even in good health, maybe you feel sluggish most of the time, or conversely, perhaps you feel high energy in the morn........ Read more »

(Partly) explaining the increase in the prevalence of autism

Steak is bad for the Heart and now We Know why

by Gabriel in Lunatic Laboratories

“Red meat is bad for your heart”, that is typically the story we hear from people. While some might take this as meat is bad for us, or that it is wrong to eat red meat, science has been trying to find a better answer to that question. After all it wouldn’t do for science to say, it just does. Well as luck may have it, new research provides details on how gut bacteria turn a nutrient found in red meat into metabolites that increase the risk of developing heart disease. The findings may lea........ Read more »

Anorexia Nervosa: Fasting and Starvation Brain Effects

by William Yates, M.D. in Brain Posts

Brain research in anorexia nervosa presents several challenges.Current knowledge of cognitive function in anorexia supports impairment in set shifting and global brain processing or central coherence.However, there are two issues that complicate understanding the underlying brain effects in anorexia nervosa.First, individuals with anorexia nervosa often have additional anxiety and mood disorders. It can be difficult to tease out the specific effects of anorexia nervosa from the effects of these ........ Read more »

Where Do All Those Leaves Come From?!

Does dreaming of exam failure affect your real-life chances of success?

by BPS Research Digest in BPS Research Digest

Why do we dream? It's still a scientific mystery. The "Threat Simulation Theory" proposes that we dream as a way to simulate real-life threats and prepare ourselves for dealing with them. "This simulation in an almost-real experiential world would train the brain to perceive dangers and rapidly face them within the safe condition of sleeping," write the authors of a new paper that's put the theory to the test.Isabelle Arnulf and her colleagues reasoned that if dreams help simulate future threats........

Producers and consumers of autism research: never the twain shall meet?

I was interested to read the paper by Elizabeth Pellicano and colleagues [1] (open-access) investigating "the views of community involvement in autism research both from the perspectives of autism researchers and of community members, including autistic adults, family members and practitioners". Quite a few results are reported including the idea that researchers "were skeptical about the possibilities of dramatically increasing community engagement, while community members themselves spoke abou........

Babies can identify the angry person

Main Point:

Babies, even 15-months-old, can identify the anger of adults. Interestingly, they have the ability to change their behavior in response to anger.

Psychologists have found that babies not only learn from their own social experiences but also from looking at social interactions of other people. This shows that babies have a good level of emotional intelligence that could be more than we think. They start learning about s........ Read more »

Reshaping the Limits of Synthetic Biology

by Gabriel in Lunatic Laboratories

Ever think you could have built something better if you had a hand in the design? Sometimes people just have a desire to make, after all the maker movement is huge for a reason. Well geneticists have a new toy tool to play with —dubbed “the telomerator”—that could redefine the limits of synthetic biology and advance how successfully living things can be engineered or constructed in the laboratory based on an organism’s genetic, chemical base-pair structure. How cool is that?!... Read more »
