Life is about stories, events and even coming back full circle sometimes. I experienced that moment of déjà vu this morning on opening a link to an article that a colleague kindly sent from Avrum Spira's lab that was published...... Read more »

Foraminifera are wonderful organisms. For a glimpse of their phylogeny, see this diagram, but keep in mind that the majority of forams are actually allogromiids, forams which build their walls of protein as opposed to scavenged material or depositing mineral substances. From the allogromiids there have been several independent origins of non-proteinaceous forams, many building their tests out of sand grains, remnants of prey or their own waste. Test-building is a complicated and highly regulated........ Read more »

Vacation homes may be harming some birds through increased nest predation, according to the findings in a new study in the journal of European Wildlife Research.
While suburban sprawl receives close scrutiny for its negative environmental impacts, vacation homes and other low density housing in more pristine areas are often overlooked.
However, as Ole-Gunnar Støen and fellow researchers in Norway show, these homes can negatively impact birds by attracting generalist predators that feed on........ Read more »

As the race to discover a new obesity drug continues, it’s important to consider what makes a good obesity drug target. Before you bother putting a team of medicinal chemists on the job of making a small molecule that could be the next big diet pill, what do you need to know about the target [...]... Read more »

The joke around some beach communities is that you can never be too thin, too rich, or too blonde. I don’t know about the first two, but a new paper suggests being blonde on a beach may be good, but you can be too blonde – if you’re a mouse.
Animal colours provide some classic cases of adaptation and natural selection. For instance, most people with even a passing familiarity with biology know about peppered moths and industrial melanism. Fur colour in mice isn’t quite as famous as moth........ Read more »

We went looking for a small black hole in our neighborhood, maybe a few hundred light-years away, and instead we found a supermassive black hole nearly 7 billion light-years away. Sometimes astronomy can be that way...

The Institute of Medicine has re-sparked discussions about limiting and further reducing resident duty hours in the United States (IOM's Duty Hours Report from Dec 2008). In response to this, the Brigham and Women's Internal Medicine residency program created an innovative inpatient team model, which was published in this month's New England Journal of Medicine.Study DesignSetting:Faulkner Hospital, an affiliated community hospital with 72 inpatient medicine bedsControl team = General Medical Se........

A new study looks at 52 conservation easements created by The Nature Conservancy (TNC) in California rangelands from 1973 - 2006 to see how the approach of this land protection strategy has evolved over time. Specifically, the study focuses on the challenge of incorporating adaptive management into a legal document that sets restrictions on land use in perpetuity...... Read more »

Non-English speakers’ access to emergency services in Australia is in the news again as a Melbourne man has been convicted of the murder of his wife.

Brain injuries caused by strokes, tumors or head trauma can, on occasion, result in Unusual Changes in Sexuality, as discussed in an earlier blog post. A new case report by Bianchi-Demicheli et al. (2010) describes a unique paraphilia1 in a married 34 year old man. The authors called it Sleeping Beauty paraphilia:This [man] felt sexually aroused from seeing sleeping women as well as from taking care of their hands and nails while they were asleep.The patient came to the attention of the authors ........

Most early e-readers are designed as dedicated device for personal reading. However, due to their high cost, limited set of functionalities, poor quality screen and short battery life, most early e-readers were deemed to be ill suited for academia (Gorissen, 2009). As a result of these deficiencies with early e-readers, most universities have never seriously considered replacing printed books with e-books. ... Read more »

Since evolution is an inherently aimless process, it often seems fickle and prone to “changing its mind”. Vertebrates came out of the oceans only to return as icthyosaurs, mosasaurs, whales, and seals. Birds took wing only to get grounded as ostriches and auks. And snakes, whose long-ago ancestor (who was also the common ancestor of [...]... Read more »
