A new angle on diving in whale sharks

by Alistair Dove in Deep Type Flow


Recently I featured a piece about how turtle hatchlings change their movement strategy several times in just the first few hours of life in order to suit their changing needs as they move across different types of sand.  Well, to go from the sublime to the ridiculous (or rather, just from the really small to the truly gargantuan) there’s a new paper out that shows that whale sharks, too, adjust the way they move according to their needs.  This new work follow........

Which is worse: your partner having a heterosexual or homosexual affair?

by BPS Research Digest in BPS Research Digest

Assuming you're in a heterosexual relationship, which is worse: for your partner to be unfaithful with a person of the opposite or the same sex? According to a pair of US psychologists, the answer depends on whether you're a man or woman. Men, they've found, are less likely to continue a relationship with an unfaithful partner who's had a heterosexual affair, as opposed to a homosexual affair. For women, it's the other way around - they're more troubled by their male partner going off with anoth........ Read more »

Alan Turing’s Reaction-Diffusion Model – Simplification of the Complex

by Kele in Kele's Science Blog

The following post is what I wrote for the first 2-day essay in my developmental biology course. It covers the potential limitations of mathematical modeling in developmental biology – specfically, the reaction-diffusion systems of the computer scientist, Alan Turing. Perhaps the larger point I try to make is that ideas that are initially and blatantly [...]... Read more »

Bufotoxin Tolerance in Keelback Snakes: recent adaptation to a new threat, or preadaptation from an ancient foe?

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

The cane toad (Bufo marinus) was introduced to Australia in what was another failed attempt at biological control.  The Bureau of Sugar Experiment Stations brought over the first cane toads from Hawaii in June of 1935 in an effort to control the cane beetle, which was destroying the sugar cane crops of northern Queensland.  About  100 [...]...

Two recent papers used very different appraoches to shed light on the genetic alterations underlying tumor growth and progression in human cancers.

Using Cadaver Legs to Study ACL Injuries

My latest post at Wired Playbook profiles Mark Drakos, an orthopedic surgeon who uses cadaver legs to test the biomechanics of ACL injuries: At times, Drakos seems like a typical orthopedist: seeing patients, prescribing meds, performing surgery.

Contagious Cooperation

by Shaheen Lakhan in Brain Blogger

Humans, and other animals, tend to cooperate with each other in a variety of social situations. Without working together toward a common goal, species as a whole would suffer and evolution may have been short-lived. In general, humans tend to be most cooperative and apt to help others when the costs are small to the [...]... Read more »

Evidence into practice: but wait, there’s more!

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

I pondered a bit about writing this post today.

Voytek Journal of Cognitive Neuroscience paper: "Hemicraniectomy: A new model for human electrophysiology with high spatio-temporal resolution"

by Bradley Voytek in Oscillatory Thoughts

(Note: this is a repost of my original post from 2009 Dec. I'm reposting some old posts to work within the ResearchBlogging.org framework.)This paper grew out of an interesting collaboration with some physicians at the University of California, San Francisco and San Francisco General Hospital, initially through a meeting between Dr. Geoffrey Manley, Dr. Robert Knight, and I. Dr. Manley has recently published several papers on the clinical benefits of performing a decompressive hemicraniectomy on........ Read more »

Fresh Recruits at the Immunological Frontlines

by Sanford- Burnham in Beaker

The immune system is always standing by, ready to fight infection. Immune cells called lymphocytes and dendritic cells hang out in lymph nodes, surveying the environment for signs of invaders and attacking infected cells when necessary.

Exercise and Depression: It's Complicated

by Neuroskeptic in Neuroskeptic

Some ideas seem so nice, so inoffensive and so harmless, that it seems a shame to criticize them.Take the idea that exercise is a useful treatment for depression. It's got something for everyone.For doctors, it's attractive because it means they can recommend exercise - which is free, quick, and easy, at least for them - instead of spending the time and money on drugs or therapy. Governments like it for the same reason, and because it's another way of improving the nation's fitness. For people w........ Read more »

Using the immune system to fight cancer

by Kevin Bonham in Food Matters

Cancer sucks. I'm sure I don't have to tell you that - it's one of the leading causes of death in developed countries, and our treatment options are pretty thin. Basically, it amounts to cutting out the tumors that can be seen, and then giving a controlled administration of poison in the hopes that the cancer cells die before you do. Don't get me wrong - advances in oncology have saved many lives, but it's no surprise that there's a lot of research happening to find better options.

Are You Glad Darvocet Got Pulled by the FDA? Are You Sure?

by Christian Sinclair, MD in Pallimed: a Hospice & Palliative Medicine Blog

I know many palliative care practitioners were cheering the news that the world's least effective opioid propoxyphene (Darvocet (w/ APAP) /Darvon)  (similar efficacy to acetaminophen) is being pulled off the market by the FDA.  Along with meperdine (Demerol) I am not sure if a medicine exists that produces as much disdain as propoxyphene amongst palliative care clinicians.

But let's look a little closer as to why this happened.  The FDA cites the increasing cardiotoxicity ........ Read more »
