Library love

by Emma in we are all in the gutter

I love libraries. I’m a member of four, not including University ones. Without libraries and the ability to borrow whatever I fancy, I think I’d be broke and living in a book-cave! So, I was sad this morning to hear that the number of adults visiting libraries in the UK has been decreasing steadily over [...]... Read more »

Neuroimaging of language: Why hasn't a clearer picture emerged?

by Greg Hickok in Talking Brains

This is the question raised in a paper by Evelina Fedorenko and Nancy Kanwisher published last year in Language and Linguistics Compass. The main point that they want to make is that language neuroimagers need to stop doing group studies and start doing functional localization in individual subjects, like the vision folks do. I don't disagree at all; e.g., see this post. In fact, we have used individual subject analyses in several of our papers (e.g., Okada & Hickok, 2006; Okada et al., in pr........ Read more »

Drug Shortages Affect Those Still in the Dark Ages – Lidocaine

EMS may be forced to do without drugs that cause more harm than benefit.

Maybe we will be smart enough to realize that we are not helping our patients with these drugs.

Neuroscience of Murder and Aggression: Epidemiology

by William Yates, M.D. in Brain Posts

This is the second in a five part series on the neuroscience of murder and aggression.  This post will address some key issues in the epidemiology of murder and antisocial personality disorder.  The number of murders in the U.S. has been stable at between 16,000 and 17,000 per year over the 2000 to 2008 time period..  The number peaked at around 24,700 in 1991.  The number has decreased since the early 1990s despite a steadily increasing total U.S. population.The reason for t........

Every patient is an experiment

Mrs. Charbin’s blood pressure just kept going up.  She felt fine—no chest pain, no shortness of breath, no headaches—but the numbers put her at risk.  At 55, her risk of developing heart disease at some point in her life is high, and is made even higher by her hypertension.  For each 20 mm Hg rise [...]...

Differentiating Skill and Luck in Financial Markets with Streaks

Speaking of luck, we just released a paper onto SSRN about luck and skill entitled Differentiating Skill and Luck in Financial Markets with Streaks. This paper, which I worked on with Andrew Mauboussin (a brilliant high school student who worked in our lab this summer), examines the relationship between skill and luck using mutual fund [...]...

Bunches and Antibunches of Atoms: Hanbury Brown and Twiss Effects in Ultracold Atoms

by Chad Orzel in Uncertain Principles

Two papers in one post this time out. One of these was brought to my attention by Joerg Heber, the other I was reminded of when checking some information for last week's mathematical post on photons. They fit extremely well together though, and both relate to the photon correlation stuff I was talking about last week.

OK, what's the deal with these? These are two papers, one recent Optics Express paper from a week or so ago, the other a Nature article from a few years back. The Nature paper inc........ Read more »

Going Nuclear: Closing the Gap Between Radiation and Reason

by Matthew C. Nisbet in Age of Engagement

In a series of posts over at Scientific American's blog CrossCheck, John Horgan describes how several recent articles and books have prompted him to re-evaluate his views on nuclear energy. He specifically recommends Gynweth Craven's Power to Save the World, discusses John Mueller's Atomic Obsession, and describes how Wade Allison's Between Radiation and Reason has challenged his views about the risks of radiation exposure. Horgan's seminal End of Science partly inspired my research focus in gra........ Read more »

Coping Strategies for Men Sexually Abused as Children

by Ultimo167 in Strong Silent Types

O'Leary and Gould (2010) tell us that in an area woefully short of research evidence, what they found in their study was that the adult male survivors of child sexual abuse can learn to cope well with that abuse history. Here, active, practical support from trusted others plays an essential role.... Read more »

Are mutualists monogamists, while antagonists play the field?

by Jeremy Yoder in Denim and Tweed

Two of the most diverse groups of living things on Earth are flowering plants and the insects that make their living from flowering plants. Biologists have long thought that the almost incessant, intimate interactions between plants and plant-eating insects might be the evolutionary cause of each group's spectacular diversity. On a smaller scale, this means that we're interested in the reasons that specific insects and plants interact in the first place—what evolutionary trails leads one insec........ Read more »

Flying Blind

by Journal Watch Online in Journal Watch Online

What you can’t see can kill you. Researchers investigating why some birds are especially prone to hitting power lines have discovered that they literally can’t see where they are flying. That means typical anti-collision efforts, such as hanging warning markers on transmission lines, won’t help fowl that fly blind.
The world’s 65 million kilometers of […] Read More »... Read more »

Will Surgery Cut Diabetes Costs?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

For patients with obesity and type 2 diabetes, bariatric surgery is by far the most effective treatment - it is, indeed, the only form of treatment that can put patients into full long-term remission.
But is surgery really a cost-effective option for health systems looking to contain the immense economic and health burden of diabetes?
