Am I lactose intolerant?

by Aaron Berdanier in Biological Posteriors

Lactose intolerance is a common condition; 70% of humans experience lactose intolerance worldwide, with abdominal discomfort, bloating, gas, and diarrhea coming from the consumption of dairy products. I have a hunch that I might be lactose intolerant, but I do not know, so I'm going to learn a little bit about lactose intolerance and do a study to assess the correlation between my eating habits and abdominal issues....

New place, new view, slow reactions and the origins of life

by The Curious Wavefunction in The Curious Wavefunction

I have been unable to blog for the past few days because I was busy moving to Chapel Hill for a postdoc at UNC Chapel Hill. I am very excited about this move and my upcoming research which is going to involve protein design and folding. Regular blogging will resume soon. Until then, happy holidays, and I will leave you with the following interesting paper published by a group from my new institution.One of the abiding puzzles in the origin of life is to explain how life arose in the relatively s........

Eugene Goldwasser & The Unforeseen Legacy of Epo

by Rob Mitchum in ScienceLife

When Eugene Goldwasser launched the project that would become his life’s work, he thought it would only take a matter of months. Since the early 20th century, biologists had predicted that a hormone they named erythropoietin must exist to promote the production of red blood cells when the body was running low. But in 1955, [...]... Read more »

Happy Christmas Lectures 2010

by Duncan Hull in O'Really?

As Tom Lehrer once sang on his winterval carol: “Christmas time is here, by golly, Disapproval would be folly, Deck the halls with hunks of holly, Fill the cup and don’t say ‘when.’ Kill the turkeys, ducks and chickens, Mix the punch, drag out the Dickens, Even though the prospect sickens, Brother, here we go [...]...

Reindeer in Britain: ecology, conservation and welfare outside their native range

by davesbrain in Dave Hubble's ecology spot

Known as caribou in North America, reindeer (Rangifer tarandus) were once widespread in Europe reaching as far south as Spain, but are now mainly found in Norway and parts of Russia, in some cases being found wild alongside domesticated herds. Whilst their bones occur frequently in prehistoric middens, the last reliable record in Britain was approximately 8,300 years ago after which they disappeared (later records are uncertain), probably due to climate change, although hunting pressure may have........

New study shows that cancer survival is improving, but there’s more work to be done

by Cancer Research UK in Cancer Research UK - Science Update

In 2007 the UK government published its landmark Cancer Reform Strategy.  As with previous government strategies, such as the 2000 NHS Cancer Plan, the report aimed to tackle the fact that the country’s cancer survival lagged behind other similar countries. But unlike previous cancer strategies, which focused on improving patients’ access to the latest cancer [...]... Read more »

Diamonds are forever – suppliers not

by Jan Husdal in

Today I am taking a closer look at how buyer-supplier relationships evolve over time. This is the buyer-supplier relationship life cycle, where supply chains are dynamic and  where supply chain partners are constantly changing: New suppliers are added, others are  contractually terminated, cease to exist or become obsolete. Needless to say, nurturing and honing these relationships also improves supply chain performance. However, as Stephan Wagner points out in his recently published article on........ Read more »

Illuminations, class identities and the contested landscapes of Christmas From Sociology In the last two decades, illuminating the outside of a house with multi-colored lights has become a popular British Christmas practice.

How Strong Are Your Relationships? Drop a Few Mails Into This Analyzer, and Get an Estimate

by David Berreby in Mind Matters

"Most people are other people," Oscar Wilde wrote. "Their thoughts are someone else's opinions, their lives a mimicry, their passions a quotation." You get the feeling, somehow, that he thought this was a bad thing. Seems likelier that it's just an inevitable fact about a species whose members ...Read More

Ergot in the Rye

by Matthew DiLeo in The Scientist Gardener

Stopping at the charity field on the way back from pollinating, I noticed a ripening rye cover crop the next field over - and decided to look for my friend, ergot.*

I couldn't believe my luck! There were little black pods sprouting from rye spikes all over the edge of the field. This is a very exciting creature to a plant pathologist - and one that's had quite an impact on European history...

Ergot is a plant disease caused by Claviceps purpurea, a member of one of my favorite fungal families........ Read more »

There are two species of African elephant

by Greg Laden in Greg Laden's Blog

Everyone knows that there are two kinds of elephants in this world: Asian and African. The Asian is the only one that can be trained and the African ones live in harmony with their environment until hunters come by and shoot them. Scratch a little deeper, and the African bush elephant lives by destroying its environment and moving on to new areas, where it destroys that environment, cycling back to the original region over generational time; Both African and Asian elephants can be trained; and........

Neuroradiology as Art

Bacon duly incorporated the x-ray directly into The Crucifixion (1933).A paper by an interdisciplinary team of S........ Read more »
