The grass isn’t always greener…

by Jim Caryl in mental indigestion

THERE you are, stood in a green grocers; you’re poring over your favourite variety of apple, but suddenly you catch the scent of something heavenly, a smell not unlike the apple you have in your hand, only better somehow. You abandon your apple and follow the scent to the next aisle where you find more [...]... Read more »

Absinthe Fact and Fiction

by Neuroskeptic in Neuroskeptic

Absinthe is a spirit. It's very strong, and very green. But is it something more?I used to think so, until I came across this paper taking a skeptical look at the history and science of the drink, Padosch et al's Absinthism a fictitious 19th century syndrome with present impactAbsinthe is prepared by crushing and dissolving the herb wormwood in unflavoured neutral alcohol and then distilling the result; other herbs and spices are added later for taste and colour.It became extremely popular in th........

Wolf recovery vs. ecosystem health

by DeLene Beeland in Wild Muse

The idea may be exotic to many wolf conservation advocates, but a group of researchers are floating a proposal to introduce very small groups of wolves to small pieces of habitat as a management tool. The goal has little, if nothing, to do with wolf recovery and everything to do with managing ecosystem health and [...]... Read more »

putting the processing pedal to the metal

by Greg Fish in weird things

Since the dawn of computers, the processing power of just about every computing device out there has been pushed ever upwards. Today’s mediocre laptops are faster than ten year old supercomputers and a modern supercomputer can carry out more than a quadrillion floating point operations per second, enough to take on complex problems in astrophysics, [...]...

Neury Thursday: Additive Teratogenic Effects of Alcohol and Metamphetamines in Utero and Neurodegeneration

by Allison in Dormivigilia

Researchers at UCLA have identified extensive neurodegeneration, particularly in the limbic and striatal areas, of infants whose mothers had used/abused alcohol and/or metamphetamines during pregnancy. The magnitude of reduced cortical volume was additive in that it was greatest for abuse of both alcohol and metamphetamines, which is common in drug abusers. ... Read more »

Does Child Sexual Abuse Cause Homosexuality?

by Ultimo167 in Strong Silent Types

Wilson and Widom (2009) add to the literature on links between having been a child abuse survivor and sexual orientation in adulthood. For a variety of possible reasons, they demonstrate that a 'tentative' link does exist between childhood sexual abuse and homosexuality, but only for men.... Read more »

Neural correlates of conscious access: implications for autism/psychosis

by sandygautam in The Mouse Trap

Image via Wikipedia

There is a recent article in New Scientist about consciousness and its neural correlates and the article focuses on work of Stanislas Deheane and his colleagues and how they are trying to get evidence and proof for the Global workspace theory of consciousness as proposed by Beranrd Baars.

Men Suffer for Too Much Small Talk

by Ultimo167 in Strong Silent Types

Mehl et al. (2010) have started to tease out the possibility that deeper, more thoughtful conversations lead to greater happiness. I can't help thinking what this might mean for men, since most of us were raised on the masculine ideal that bland small-talk is the only way to go.... Read more »

Mirror Neurons - The unfalsifiable theory

by Greg Hickok in Talking Brains

I recently had the pleasure of giving a lecture on mirror neurons at UC San Diego which is a very active locale for folks working on the human mirror system. I expected a lot of push-back on my critical views of mirror neurons, and I wasn't disappointed. One of my major points of emphasis is and has been that if the mirror neuron system is really important for action understanding, then damage to action execution should result in action understanding deficits. I have pointed out that this predi........ Read more »

Calorie Restriction Reduces Lipofuscin Buildup, is Good for Nerves

by Reason in Fight Aging!

The long-term practice of calorie restriction has been demonstrated to slow almost every aspect of age-related change and degeneration in those mammals most exhaustively tested (i.e. mice and rats). So far the primate and human studies are producing the same sorts of result, but it will be another decade or more before the present research community has covered all the bases in humans. Still, the evidence to date is very compelling: regular exercise and calorie restriction kept up over the years........ Read more »

Voracious damsels, helpless midges, facilitative shredders…life in a Costa Rican bromeliad:

Carin’s paper pick o’ the week, March 19, 2010:
Much of what we know about food web structure comes from work that focuses on negative interactions between trophic levels (e.g. predation and competition).  However, facilitative (positive) interactions should not be ignored when it comes to elucidating the importance of food-web interactions.  The work outlined in this [...]...

Your Friday Dose of Weird: Male pipefish show the dark side of male pregnancy

by Laelaps in Laelaps

At almost every aquarium I have ever visited with a seahorse exhibit, the plaque in front of the tank says the same thing: in seahorses and their relatives, males, not females, carry the babies. It is always interesting to watch the reactions of visitors to this curious fact. Adult men, for instance, sometimes seem unsettled by the thought of male pregnancy, but the reproductive reversal among the fish is often seen as kinda cute ("How sweet. A fishy dad taking care of his kids!"). As shown........ Read more »

Linking Footballers, Fingers and Sexual Selection

by Isabelle Winder in Going Ape

Footballers, particularly those who play at national or international levels, sometimes seem to have it all: celebrity, fitness, money and success. But rather than just supposing that this is the result of football's cultural status and importance, researchers have also suggested that it is the result of natural selection - not the survival of the fittest, as modern medicine and cultural systems ensure that in the Western world at least, most people have the chance to live, but perhaps the succe........

The plight of Hawaiian birds

Just last week, two Hawaiian bird species from the island of Kaua’i and their respective habitats were put on the endangered species list along with a Hawaiian fly and 45 types of Hawaiian plants. However, while the action signifies movement from the Obama Administration toward protecting at-risk species and their habitats, the listing does not come a second too soon: Recent research shows U.S. birds, especially in Hawaii, are in great peril....

New analysis of pesticides and bee colony collapse disorder

European bee populations are on the decline worldwide.   Who cares?  These bees are major pollinators of crops and therefore perform, for free, a vital ecological service worth about $U.S. 14 billion per year.  Not to mention the many other species of non-crop flowering plants that reproduce with the help of insects like this.
The recent kind [...]... Read more »
