A group of over 20 biodiversity experts from a slew of international conservation agencies have a paper out in Science bemoaning the state of the biodiversity indicators agreed in 2006. These indicators are important because they are supposed to be used to track progress towards fulfillment of the promise made by Parties under the Convention [...]... Read more »

ome posts take quite a while to write. This is a response to Candy Minx and Martin Rundkvist who were discussing the Antikythera Mechanism in 2006. Candy Minx thought the Antikythera Mechanism was an expression of what was already known and embedded in a society through things like myth and ritual. Martin thought that the mechanism was far more complex. Originally I planned to write a fence-sitting compromise. Here it is. This is science turned up to 11.... Read more »

In most of software and database development the changes that are coming along all the time seem to be tweaks and polishes on the existing strategies. Every so often, though, there’s a big shift in the strategy or mechanism. This week the JBrowse paper I read made me realize that is now firmly underway. Today’s tip of the week will introduce JBrowse, and here I’ll describe some of the reasons this is a game changer.... Read more »

Good news for sun-loving Germans. By 2071-2080 parts of their country are going to have the climate that parts of Greece have now. That’s according to a paper in Plant Ecology which ran a bunch of climate change models for Europe. Have a look at the money map.

Seasonal Affective Disorder (SAD) or Winter Depression can be succesfully treated with bright light therapy. Across studies, 53% of cases of SAD remit with bright light therapy. This involves sitting in front of full-spectrum lights that mimic sunlight on a regular basis — typically for about 30 minutes to 60 minutes each morning. Sometimes one [...]

Sci is still tracking her caloric intake every day for the goddess (well, mostly for herself, but also for the goddess). It's very long, slow haul. Sci still considers days when she eats no more than 2000 calories (preferably a little less) as good days. That may not seem like much of a diet, but compared to my previous intake, it's quite a big cut. And many days I just don't make it.
But obviously, this has stayed on my mind. I can't help thinking about how we register food in the brain........ Read more »

Physiognomy - inferring personality traits from facial features - was outlawed by King George II in 1743, and has for many years been dismissed as a pseudoscience. However, modern research is showing not only that observers readily make inferences about other people's traits based on their facial appearance, but that these inferences are often highly accurate. For example, people can use facial appearance to judge a man or woman's sexual orientation and to predict the success of chief executives........ Read more »

Some time back Deepak Singh wrote an interesting post The curse of BLAST describing how BLAST has become synonymous to the bioinformatics. Although his article highlights a general perception about bioinformatics especially within bench scientists it does not account for the reason which lead us to generalize bioinformatics with BLAST or any other protocol.

A lovely new paper reports in fascinating detail on a man who lost a uniquely large portion of his brain: Bilateral limbic system destruction in man.The authors, Feinstein et al from Iowa City, have studied the patient, "Roger", for 14 years. Roger was born in 1952, and lived a fairly uneventful life until he contracted herpes simplex encephalitis (HSE) at the age of 28.HSE is an extremely rare condition in which the herpes virus infects the central nervous system. Untreated, it is fatal in 70% ........ Read more »

Imagine your neighbor has a dog that regularly escapes her yard. One day you see the dog escape and return it to her. She thanks you by giving you a piece of delicious home-made apple pie. This happens several days in a row. Then one day when you return the dog, there's no pie, no thanks, and no explanation. Would you return the dog the next time it escapes?
You might be disinclined. But what if there had never been any reward? Wouldn't returning her dog be the right thing to do?

In regards to sexual reproduction, the selection of potential mates can generally be thought of as functioning along one of four lines; through identifying Good Genes, receiving Direct Benefit, via Sensory Bias and by Fisherian Runaway. However, even though most species have adapted to one of the core strategies listed above, the methods of selection themselves are far from being restrictive. In fact, these strategies of mate choice may operate independently, collectively or in conjunction wit........ Read more »

Surgery is supposed to hurt. Well maybe not ’supposed’ to, but most people expect some pain after surgery – as one doctor said to me, it’s really ‘planned trauma’.

A man accused of a crime is brought into a police interrogation room and sits down at an empty table. There’s no polygraph equipment in sight, and the typical two-cop questioning team isn’t in the room either. Instead, one officer enters the room with a piece of paper and a pencil in his hands. He sets them in front of the suspect, steps back, and calmly says, “draw.”
That’s a greatly oversimplified description of what could happen in more actual interrogation ........ Read more »
