Exercise – It Works For Depression

by Shaheen Lakhan in Brain Blogger

I’m currently reading with great pleasure Tony Schwartz’s new book, The Way We’re Working Isn’t Working – The Four Forgotten Needs That Energize Great Performance. Schwartz’s main premise is that we need balance — between activity and rest on the physical level, between performance and renewal on the emotional level, between left and right brain [...]...

The Obesity Myth Myth

by Arya M. Sharma in Dr. Sharma's Obesity Notes

From time to time the media loves to write stories on the Obesity Myth.
These stories come in two flavours - the first one denies the very existence of an obesity epidemic, attributing the rise in obesity statistics to moving definitions that “suddenly” make everyone obese simply by shifting the goal post.
The second flavor of obesity [...]... Read more »

On coupling

by Richard Grant in Confessions of a (former) Lab Rat

No, not that sort of coupling. I was writing up today's Faculty Dailies, catching up on (yet) another paper about how ribosomes control the rate of transcription. As has been known for decades, bacterial transcription and translation are tightly coupled....... Read more »

Narcotic treatment contracts and the state of the evidence

by Peter Lipson in Science-Based Medicine

Opium derivatives—and later, synthetic opioids—have probably been used for millennia for the relief of pain. Given human biology, they’ve probably been abused for just as long. Opiate use disorders are a daily fact for primary care physicians; the use of these drugs has become more and more common for chronic non-cancer pain. [...]... Read more »

Is Junk Food Addictive?

by Walter Jessen in Highlight HEALTH

In a recent paper in Nature Neuroscience, two researchers at the Scripps Research Institute in Florida report that obese rats with extended access to what they deemed "palatable food" – bacon, sausage, cheesecake, pound cake, frosting and chocolate – exhibited compulsive like eating behavior, much like rats with extended access to cocaine or heroin....

An egregious act of methodological imperialism

by David Poeppel in Talking Brains

In an 'Update' in a recent issue of TICS (Weak quantitative standards in linguistics research. 10.1016/j.tics.2010.03.005), Gibson & Fedorenko (GF) commit an egregious act of methodological imperialism, and an unwarranted one, at that.GF complain that one key source of data for theoretical linguistics (and particularly for syntax and semantics research), acceptability or grammaticality judgments, are not "quantitative." They advocate for some intuitive standard of what it means to do the 'ri........ Read more »

Narcotic treatment contracts and the state of the evidence

by PalMD in White Coat Underground

Not an opium poppy
I took this picture a couple of days ago. This poppy popped up as a volunteer in my front bed. It's about four feet tall and the flower is about 5 cm in diameter. It's not an opium poppy, but it could pass, and I've been looking for an excuse to use the picture.

Opium derivatives---and later, synthetic opioids---have probably been used for millennia for the relief of pain. Given human biology, they've probably been abused for just as long. Opiate use disorders are a da........ Read more »

Acupuncture, Adenosine and Cycling Fish

by Lorimer Moseley in BodyInMind

You may have heard this story as it is all over the popular press right now. We are told that scientists have discovered some of the mechanisms underlying acupuncture analgesia. As always with alternative therapy reports the media have enthusiastically bitten off the hand of the press release (see this great account from the blog [...]... Read more »

Biodiversity is a delicate recipe

by Katie Kline in EcoTone

Unless you enjoy cooking regularly, you probably would not have known the sequence for preparing corn chowder just by the taste. According to a study recently published in Science Express, biodiversity is a similar process. Some scientists go about recreating an ecosystem by adding all of the elements at once into an experiment. The results, however, usually do not replicate the original ecosystem that the researchers were trying to reproduce.

The assessment of emotional expression in dogs

by The Dog Zombie in The Dog Zombie

“The assessment of emotional expression in dogs using a Free Choice Profiling methodology” (Walker et. al., Animal Welfare).Do different people tend to have overlapping or at least complementary ways of describing dog behaviors? And if they do, can a computer put together a behavior scale out of those descriptions, even without any understanding of what’s actually being described? Put a different way: Can we describe a group of observations of dog behavior using a fancy statistical techniq........ Read more »

Another overhyped acupuncture study misinterpreted

by David Gorski in Science-Based Medicine

Perhaps the most heavily studied of “alternative medicine” modalities is acupuncture. Although it’s hard to be sure as to the reason, I tend to speculate that part of the appeal to trying to do research in this area is because acupuncture is among the most popular of actual “alt-med” modalities, as opposed to science-based medical [...]...

Experiments in cultural transmission and human cultural evolution

by Wintz in A Replicated Typo

For those of you familiar with the formal mathematical models of cultural evolution (Cavalli-Sforza & Feldman, 1981; Boyd & Richerson, 1985), you’ll know there is a substantive body of literature behind the process of cultural transmission. It comes as a surprise, then, that experiments in this area are generally lacking. For instance, if we look [...]... Read more »

A vaccine to prevent breast cancer? Not just yet

by Cancer Research UK in Cancer Research UK - Science Update

Last week it was viruses, this week it’s vaccines. So, are we really on the verge of a ‘revolutionary vaccine’ that could ‘end breast cancer’ – as some of the media have stated? No. Not yet, anyway. The headlines in question originated from a paper in Nature Medicine, in which US-based researchers described a series [...]... Read more »

Island-Hopping Ceratopsians Made it to Europe

by Brian Switek in Dinosaur Tracking

Ceratopsians, or the “horned dinosaurs” such as Triceratops and Centrosaurus, were among the most distinctive members of dinosaur communities in North America and eastern Asia during the Cretaceous. Even so, bits and pieces of fossil bone collected by paleontologists over the years have hinted that this famous group of dinosaurs had a much wider range [...]... Read more »

Why is running good for you?

by Aaron Berdanier in Biological Posteriors

This weekend I am running in the Kettle Moraine 100, in a 31 mile leg of the 100 mile relay. Given that event, this is my first running science blog post - a slight tangent from ecology...

Where do the health benefits of running come from? Physiologically, people's metabolism changes. Or, more specifically, certain metabolites increase in the body, which trigger cellular responses (for example, fat burning).

Mutation and Selection in a Lung Cancer Genome

by Daniel Koboldt in Massgenomics

A letter to Nature this week presents the whole-genome sequencing of a non-small-cell-lung cancer tumor. Over 500 validated mutations (530 SNVs and 43 structural variants) offer an unprecedented view of genetic variation and selection in solid tumors.

Using arrays of self-assembling DNA nanoballs (DNBs, i.e., the Complete Genomics platform), Lee et al sequenced a primary lung [...]... Read more »
