Asian Strokes Are Not Same as Western

by Steve Parker, M.D. in Advanced Mediterranean Diet

The higher the consumption of saturated fat, the lower the risk of death from stroke, according to Japanese researchers in a recent American Journal of Clinical Nutrition. 
Most physicians in the West would have predicted the opposite: saturated fats increase your risk of stroke.  Western physicians tend to think most strokes and heart attacks are caused [...]... Read more »

Resilience, catastrophising and positive emotions

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Catastrophising, or thinking the worst, is one of those psychological factors that we know influences distress and disability in people with chronic pain. It’s quite a common phenomenon, and sometimes can stand us in good stead – after all, if we can think of the worst things that can happen, then plan to avert those … Read more... Read more »

Morningness versus Eveningness

by Dr Shock in Dr Shock MD PhD


Interesting topic: morningness versus eveningness. My self I am a morningness person. Early to rise, get most of the work done in the morning.
In colloquial terms, individuals oriented towards morning types were often labelled ‘‘Larks”,
and individuals oriented towards eveningness were labelled ‘‘Owls”
Morningness and eveningness is part of our chronotype. Besides heritable factors our chronotype [...]

Write for your brain

by NeuroKüz in NeuroKüz

Remember the days when writing by hand was more common than typing?While those days may be gone, the ability to write by hand is indisputably still useful. This is why getting writer's cramp -- an often-painful condition that inhibits one's ability to write -- can be quite an annoyance.Luckily, there are several forms of intervention that can be effective in alleviating writer's cramp. In a new study published in NeuroImage, Oliver Granert and colleagues examined how a couple of treatments for w........ Read more »

5 ways to gain a lover

by aimee in misc.ience

Yes, it is a shameful, shameful misappropriation of a great song, but I couldn’t help myself.

Not even a little bit.
And seriously, there are, apparently, five different styles of flirting.  An ‘inventory’*, if you will.  And what, pray (or, possibly, prey) are they?  Read on, dear reader!
Traditional
This is based very much in traditional gender roles.  You [...]

The diversity of values held by conservation scientists and why this matters

by Phil Camill in Global Change: Intersection of Nature and Culture


Right up there with climate change, biodiversity conservation is one of the most challenging issues at the intersection of nature and culture.  Part of this challenge arises because of genuine differences in how people value other species.
In an interesting forthcoming article in Conservation Biology, Chris Sandbrook and colleagues at Cambridge University argue that these value [...]... Read more »

Evolution: A Game Of Chance?

by Christie Wilcox in Observations of a Nerd

One of the toughest concepts to grasp about evolution is its lack of direction. Take the classic image of the evolution of man, from knuckle-walking ape to strong, smart hunter:

We view this as the natural progression of life. Truth is, there was no guarantee that some big brained apes in Africa would end up like we are now. It wasn't inevitable that we grew taller, less hairy, and smarter than our relatives. And it certainly wasn't guaranteed that single celled bacteria-like critters ended up ........ Read more »

Copulatory Plugs: Was it As Good for You As It Was For Me?

by Allie Wilkinson in OH, FOR THE LOVE OF SCIENCE!

Just who exactly benefits from copulatory plugs, anyway?  Mating plugs have been documented in a broad range of animal groups, including insects, arachnids, reptiles and rodents and range from a gelatinous substance in bees and nematodes, to a more solid, coagulated protein mixture in primates, or even the whole appendage breaking off in the vagina.

The BIG picture: Ecological effectiveness

by DeLene Beeland in Wild Muse

In an age when endangered species are often recovered just as much by force of legislation, á la the Endangered Species Act, as they are by scientific principles, I often find myself weighing the Big Picture of ecological effectiveness against the minutae of things like genes and mere numbers.

Tales of Death

by Merry Youle in Small Things Considered

by Merry

Bacteriophages are expert killers, having been delivering death to bacteria for several billion years. We are not the first organisms to recognize their skill. Bacteria themselves have borrowed the tail of a phage and fashioned from it a targeted bacterial killer for their own use.

We first became aware of this in 1925 when André Gratia observed that E. coli produced a proteinaceous agent that efficiently killed other E. coli, but not unrelated bacteria. Being proteinaceous and s........ Read more »

Medicine from the deep

by Noam Ross in Noam Ross

Normally I'm fairly skeptical of studies that attempt to put one big number around the value of a global ecosystem service.  In general, studies at such coarse spatial scales have more uncertainty and are not useful at the regional and local levels where decisions are generally made.  Nevertheless, I'm intrigued by this study in the latest Ecological Economics that attempts to put a value marine genetic diveristy on the development of future pharmaceutical products:

Lots of back and forth in molecular motors

by Joerg Heber in All That Matters

Designing organic molecules that perform repeated mechanical motions is not easy. The molecule needs to be robust on the one hand, and on the other hand have different stable states between which it can alternate. Achieving such complex functionality requires careful design considerations. Nature has solved this problem, and molecular motors perform important functions in living organisms, [...]...
