Hawksbill Hope

by Journal Watch Online in Journal Watch Online

Things may not be as bleak as they once seemed for one endangered sea turtle. A new survey finds that hawksbill turtles are more widespread in the eastern Pacific than earlier studies had suggested. Still, the “comparatively optimistic” findings still show that the turtle continues to be highly endangered and will need help to survive. […] Read More »... Read more »

Concavenator: an incredible allosauroid with a weird sail (or hump)... and proto-feathers?

by Darren Naish in Tetrapod Zoology

The last few weeks have been pretty exciting for people interested in theropod dinosaurs.... but then, you could say this about most weeks: new theropods are constantly being published.

Last week saw the publication of the weird, functionally two-fingered, short-footed maniraptoran Balaur bondoc from the latest Cretaceous of the Haţeg Basin in Romania (Csiki et al. 2010) [left foot of Balaur shown here, from BBC News]. When Balaur was alive, the Hateg region was an island, so this was ano........ Read more »

Vitamin B and Brain Atrophy in Alzheimer's Disease

by William Yates, M.D. in Brain Posts

Disclosure:  I am not a big supporter of vitamin therapy for clinical neuroscience disorders.  Of my previous 131posts, I have only referenced on study related to vitamin therapy---that was a study that found no improvement in treating dementia with vitamin E.  Nevertheless, today's post focusses on a new study of B vitamins in mild cognitive impairment. I ran across a randomized controlled trial using B vitamins in a controlled study of brain atrophy (Hat tip to BBC news).  ........ Read more »

Selective cell death mediated by small conditional RNAs

The Doctor Is… Online

by Shaheen Lakhan in Brain Blogger

Medical professionalism is becoming hard to define in a digital age that blurs the line between public and private information. A majority of college students, health professional students, and young health care practitioners have social networking accounts and an active online presence. However, these accounts and profiles may be detrimental to individual and collective professionalism. [...]... Read more »

Eating your own brain: Ocean of Pseudoscience repost

by Zen Faulkes in NeuroDojo

Southern Fried Scientist decided to feature a week of surreal science related to the oceans. I take this opportunity to be a lazy blogger and repost this piece (slightly rewritten) from May 2008.

Adult sea squirts (also known as tunicates or ascidians) are sessile animals. As adults, they really don't move. But if anyone has heard about sea squirts, they’ve probably hear that little sea squirts start life as smart little tadpoles, searching this way and that for a place to land. Once they’v........

The naked years

When I talk about sexual selection I usually make sure to have an accompanying visual of a peacock to go with the post. But really I could have used a dandy as an illustration, or perhaps in our day & age “The Situation”. Unlike the peacock much of what passes for human “plumage” is not [...]... Read more »

As we approach the ninth anniversary of 9/11, researchers writing in Psychological Science this week analyzed 85,000 text pages sent through pagers during the 2 hours before and 18 hours after 9/11 took place. (You do remember what a pager is, don’t you?) WikiLeaks, the website in the news lately for other reasons, has made the 573,000 lines consisting of 6.4 million words freely available on its website for the past year.
What would these 85,000 pages tell us about the human emotion tha........ Read more »

The link between transcription, mutation, and evolution Part I

by Levi Simonson in Learnest Scribbler

Proposed and described non-adaptive mechanisms for evolution have been gaining favor among the Biology community.  Of course, as is always the case in an interesting debate, neither side is without its flaws, and recently I was given an article by Kele that is a prime example of this.  The article in question is- Evolutionary Chance Mutation: A Defense Of The Modern Synthesis’ Consensus View, by Francesca Merlin.  In this article, Merlin formulates a rebuttal to Jablonka and Lam........

Lamme model - less emphasis on introspection

by Janet Kwasniak in Thoughts on thoughts

According to Victor Lamme, the reason that the study of consciousness is so difficult is that it gives priority to introspection and behaviour so, as a result, we are fooled into thinking that we know what we are conscious of. By adding evidence from neuroscience into the mix, he hopes to [...]... Read more »
