Improving scan results

by Janet Kwasniak in Thoughts on thoughts

p { margin-bottom: 0.08in; }
Yarkoni and others make a plea for collaboration and cumulative science in the mapping of brain functions, and in doing this they give much needed cautions to those of us that follow the images without any first-hand experience of a fMRI technology. I list here what they say are the short [...]... Read more »

A Fistful of Teeth – Do the Qesem Cave Fossils Really Change Our Understanding of Human Evolution?

by Laelaps in Laelaps

A handful of fossil teeth found in Israel’s Qesem Cave, described in the American Journal of Physical Anthropology and attributed to 400,000 year old members of our own species in multiple news reports, are said to rewrite the story of human evolution. This discovery doubles the antiquity of Homo sapiens, the articles say, and identify [...]... Read more »

Detecting facial emotions: Women vs Men

by Psychothalamus in Psychothalamus

Do women really recognize facial emotion better than men? Existing literature on the subject remains contradictory with some studies showing a female advantage (albeit with small effect sizes) and others failing to find any gender differences. Hoffman and colleagues (2010) suggest that expression intensity is an important factor mediating gender differences in recognizing emotions and that while women do recognize facial emotions better than men, this advantage only exists for subtle emotional f........

Tuesday Crustie: Terrible claw

by Zen Faulkes in NeuroDojo

Everyone knows “dinosaur” means “terrible lizard.”

Meet Dinochelus: “terrible claw.”

Although it’s described as a “lobster” in the paper’s title it’s more of a size that most people would describe as a prawn, or maybe even a shrimp, It’s maybe 10 centimeters long.

I’m pleased that this animal has a prehistoric type of name,* because its claw reminds me of nothing so much as the gaping maw of dozens of reconstructions of marine reptiles. It’s stunning. Click the ph........ Read more »

Denisova the Menace II: Nuclear story

by zacharoo in Lawn Chair Anthropology

Earlier this year, I discussed the publication of a mitochondrial DNA study from a 50,000 year old pinky bone from Denisova in Siberia. The big story there was that the mtDNA of this specimen was twice as divergent (different) from modern humans as Neandertal mtDNA. This suggested to researchers that there was this rogue human group (some [not I] might say 'species') running around Eurasia around the time of the Upper Paleolithic.
Well now they've sequenced the nuclear genome of one of a Denisov........ Read more »

Echinacea for Colds and the Flu

by Scott in Science-Based Pharmacy

Colds and the flu (influenza) are among the most frequent and universal illnesses we all experience. Yet we don’t have any truly effective treatments for them. Sure, there are plenty of products available to treat the symptoms. And there are vaccines and some prescription treatments for influenza, which have modest effects.  But it would be nice if there was something that reliably [...]... Read more »

When Is A Placebo Not A Placebo?

by Neuroskeptic in Neuroskeptic

Irving Kirsch, best known for that 2008 meta-analysis allegedly showing that "Prozac doesn't work", has hit the headlines again.This time it's a paper claiming that something does work. Actually Kirsch is only a minor author on the paper by Kaptchuck et al: Placebos without Deception.In essence, they asked whether a placebo treatment - a dummy pill with no active ingredients - works even if you know that it's a placebo. Conventional wisdom would say no, because the placebo effect is driven by th........ Read more »

Narwhal: Unicorns of the Sea

Also known as the "unicorn of the ocean," the narwhal (Monodon monoceros) is one of the rarest and strangest whales of the world.

Raw Oysters, especially ‘wild’, are excellent sources of several minerals, including iron, zinc and selenium, which are often low in the modern diet. They are also an excellent source of Vitamin B12. Oysters are considered the healthiest when eaten raw on the half shell.
A search on PubMed also reveals that eating these creatures can be [...]
