A new study in the journal Auk finds evidence that mercury contamination can modify the singing behavior of birds.
Kelly Hallinger and fellow researchers from William and Mary's Cristol Lab recorded and analyzed bird songs from four species at sites along the mercury-contaminated South River in Virginia. They also studied birds of the same species at nearby uncontaminated sites.... Read more »

An outline of the upper jaw of Ptychodus mortoni showing the position of the new fragment, and a comparison of the size of the shark next to an adult human. (From Shimada et al., 2010)
The study of prehistoric sharks is no easy task. Specialists in other branches of vertebrate paleontology at least have the reasonable hope of discovering complete skeletons of their subjects; except in instances of exceptional preservation the scientists who study sharks typically only have teeth and a few ........

Man chasing rabbit
(From “Fliegende Blätter”, Munich, 1889)
Everyone knows about rabbits in Australia. Introduced in the mid-1800s, they multiplied ridiculously and are their way across the country, leaving barren devastation behind them.
Myxomavirus, a poxvirus that originated in South America, was introduced in the early 1950s and temporarily controlled the rabbit population, cutting their numbers [...]... Read more »

Uri Alon, a PI in the Weizmann Institute in Rehovot, Israel, recently published an article in Molecular Cell where he discusses how to build a motivated research group.
Motivation in a research group is very important as that is the way that work actually gets done. Its not enough to go uninspired through the motions and conduct experiments because if it doesn’t work out – what is going to push you to keep trying? I personally have spoken to many involved in research asking what i........ Read more »
People hold strong feelings about the meanings of irony and sarcasm. Just look at the reaction to Alanis Morissette's global hit 'ironic' - despite commercial success, the apparent misunderstanding of irony conveyed by the song provoked a chorus of derision (at least everyone agreed that this state of affairs was ironic). So I'd say it's with some courage that Melanie Glenwright and Penny Pexman have chosen to investigate the tricky issue of when exactly children learn the distinction between sa........ Read more »

Cosmology has, for a decade, had its "standard model", which largely explains most of the cosmological phenomena that astronomers are able to observe. Except for a relatively small number of things that don't seem to make sense in the model. Prominent among the latter are dwarf galaxies – by one definition, galaxies having less than 10% of the total mass of the Milky Way.The standard model of cosmology is known officially as the Λ-cold-dark-matter model – ΛCDM.

This article discussed in this post, isn’t recent but the conclusion is very nuanced which isn’t always the case with publications especially in news media about social networking and kids or adolescents. Seems that politicians are advocating measures to restrict social networking for children in order to prevent assumed online sexual exploitation and Internet harassment.

A few analyses from the Coping With Cancer Study have been published recently, all in the Journal of Clinical Oncology. We've published extensively about the CWCS (see here for more). Briefly, it was a prospective, US multi-institutional study of several hundred advanced cancer patients (& their family caregivers) which measured at baseline, among many things, characteristics of patient coping, communication with clinicians, and care preferences. Patients were followed through death, and ........ Read more »

NEJM has an editorial discussing withholding information from patients. It's a practical, casual discussion of 1) the fact that in real life we withhold information from patients all the time (e.g. don't go into all the details as they can be confusing, overwhelming, or superfluous), and 2) the fact that we decide all the time to withhold certain major pieces information out of a desire to protect the patient emotionally. It's the latter that is the real issue (e.g. not talking with a leuke........ Read more »

Last year, I wrote about a scientific controversy over the structure of the influenza M2 proton channel, particularly over the protein's binding site for adamantane type anti-flu drugs. The Schnell/Chou model, based on solution NMR, had the drug binding to the outside of the channel, within the membrane (at a 4:1 drug:protein ratio). On the other hand, the Stouffer/DeGrado model had the drug binding inside the channel (1:1 ratio), based on X-ray crystallography studies.
A new study was recently........ Read more »

Yet what is often overlooked in our view of these two, clearly connected phenomena is the thread that weaves them together: the ability to coordinate [...]... Read more »

Diabetes drug being tested for addiction.
It’s a mouthful: peroxisome proliferator activated receptor gamma (PPAR-gamma).
Peroxisomes are specialized subunits inside cells that help metabolize various substances, including fatty acids and certain toxins. A blockbuster member of this drug family—Avandia—is a much disputed but immensely lucrative diabetes medicine that may cause heart failure.

Just about every article I read on women’s preferences for sexual dimorphism in men points out that the data are consistent with the good genes hypothesis. There are a couple of technical variations of this hypothesis, but they all are based on the reasonably well-established connection between testosterone and impeded immune system functioning. The idea [...]... Read more »

I just came back up from our cellar, where I was looking through a couple of cardboard boxes that I hadn’t opened since we moved from Colorado. The boxes are full of research papers on benthic foraminifera, left over from my days of doing science. I ventured down there because a researcher from Sweden wants to have a reprint of one of my papers, and I don’t have an electronic file of it (I will after this).
Turns out the paper wasn’t in either of the two boxes, but in ........ Read more »

Many neuroscientists think of the thalamus – a compact structure lying right in the centre of the brain – simply as a relay station, where sensory information from the periphery converges and is then passed on to the cortex. The cortex is thought to be the site of perception and cognition, with different cortical areas specialized to subserve different functions. Communication between cortical areas can be mediated by axonal tracts running in the white matter of the cortex. This leads ........ Read more »

For a couple of years now, the focus of researchers on factors that identify ‘high risk’ of ongoing disability has turned from patients and onto providers. I’ve written before that health provider’s own beliefs about pain, particularly pain-related anxiety and avoidance, can change the advice they give. This can lead to less ‘reassurance’ about [...]...

There's more evidence that many children have a mental health disorder and not enough get help. The first representative survey of children in the United States found that 13% of children ages 8 to 15 had at least one psychiatric disorders during one year.
