Whenever I think of old-growth forests, I envision the redwoods of Northern California or the Amazon region of South America - not the continent of Europe where forest destruction and intensive management have been widespread for millennia. However, in parts of Europe, areas of virgin forest still exist - mostly in Russia, but also in other countries, as well.
A new study in the journal Biodiversity and Conservation reflects a growing effort to identify and protect these remnant old-growth fo........ Read more »

Throughout the natural world species have discovered the benefits of cooperating to achieve common goals. Wolves hunt together in packs, many birds seasonally migrate in flocks and no bee will hesitate to work or give its life for the colony. But when cooperation becomes the norm, cheating can become a fruitful strategy on [...]... Read more »

Both the hidden and informal curriculum take place after or next to the theoretical teaching, the formal teaching and has an important part in the shaping of the medical students’ professionalism and professional values. Moreover, these forms of the curriculum have a major impact on the learning potential of med students. Yet little is known [...]

I’ve written a lot here recently about the Athapaskan migration(s) into the Southwest. It’s a very interesting topic in a lot of ways. I find it especially fascinating because although the evidence that it happened is very strong, nothing else about it can be easily determined. We know that at least one migration of Athapaskan-speakers [...]... Read more »

People are slower at responding to tactile stimuli than to input from the other senses. It's not immediately obvious why this should be. It's unlikely to be for mechanical reasons: the retina in the eye is slower at converting input into a neural signal than is the skin. Psychologists think the answer may have to with attention. Perhaps we're not so good at keeping our attention focused on the tactile modality compared with the others. Now Louise Connell and Dermot Lynott have added to the pictu........ Read more »

One of the great things about this site is that people often bring products or research to our attention that we otherwise might have missed. This occurred yesterday in the comments section of Peter's recent post on Acai berry scams, when one of our readers brought up the use of Human Chorionic Gonadotropin (HCG) in the treatment of obesity. The website that we were provided smacks of weight loss gimmickry - notably the promise of an obesity "cure" and "near 100% ........ Read more »

Regardless of your shape or size, physical activity has been shown to add years to your life, and life to your years. But believe it or not, the benefits of physical activity are not restricted to exercise performed in the gym. In fact, one of the easiest ways to improve your health may be through increasing the amount of low intensity physical activity you perform throughout the day. For example, simply increasing the number of steps that you take each day is ........ Read more »

Originally, Popeye the Sailor gained strength from rubbing the head of a rare chicken.

Prion protein (PrP) is the focus of some neurodegenerative diseases. It is believed that misfolded prion protein (PrPsc, or “scrapie”) is the infectious agent responsible for bovine spongiform encephalopathy (BSE), and Creutzfeldt-Jacob disease (CJD), among others. PrPsc propagates by conversion of normal (healthy) prion protein (PrPc).
Several questions arise in the research community. Two of [...]... Read more »

As spring approaches, cocaine users might take note of further evidence of a connection between high ambient air temperatures and accidental overdoses.
A study published recently in the journal Addiction used mortality data from the Office of the Chief Medical Examiner in New York City from 1990 to 2006 to determine the frequency of cocaine-related overdoses (itself an enterprise fraught with uncertainty and argument over listed causes of death).........

Can contingency planning increase flexibility and minimize risk exposure to supply chain disruptions? Obviously yes, but what is it about the contingency planning process that relates to flexibility?

Sex might be fun but it's not without risks. As your partner exposes themselves to you, they also expose you to whatever bacteria, viruses or parasites they might be carrying. But some animals have a way around that. Ekaterina Litvinova has found that when male mice get a whiff of female odours, their immune systems prepare their airways for attack, increasing their resistance to flu viruses.
Litvinova worked with a group of mice that were exposed to bedding that had previously been soiled by ........ Read more »

Of the many mysteries surrounding human evolution, the question of why humans, alone out of all the apes, display a strong tendency towards being right-handed is perhaps less well known than uncertainties about our locomotion, brain size and cultural capacity. Yet the fact remains, over 90% of humans are right handed, and strongly so - there are proportionally few left-handed individuals and very few ambidextrous ones. Handedness is a manifestation of laterality - having a behaviourally dominant........ Read more »

Often, the cutest things come in small packages. Not so with Ralph - at 42 lbs, he's a record-breaking rabbit.
Ralph comes from a huge family - both his mother and father previously held the world records for largest rabbit in length and weight. And though he's already the biggest bunny in the world, Ralph is still growing! No one knows how immense this ball off fluff will get, but however big he ends up being, he's sure to still be 100% adorable.

We discussed supernovae a bit in this recent post on gamma-ray bursts. There is now interesting new information on the connection between supernovae and gamma-ray bursts from two recently-described supernovae with atypical properties.Let's first review a little. Gamma-ray bursts (GRBs) are identified by detection of relatively brief (usually less than a few minutes) but highly energetic emissions of gamma rays. Although there's a great deal of diversity, most events fall into one of two categori........ Read more »

I thought i would post the Scottish Physical Activity strategy to demonstrate that a good strategy requires effective implementation. The document Preventing Overweight and Obesity in Scotlandidentified that Scotland was the third most obese country in the world after the USA and Mexico.
