But you started out so well!

by TwoYaks in Gene Flow

What colour is the colour for little girls? Well, if you were raised in a "Western" context, the answer is really simple. It's pink, duh. But if you think about it, there's no reason why pink should be for little girls per se, or why boys have blue. Why can't girls have brown, and boys have tangerine? It's just as logical as pink for girls, blue for boys. And I like the colour tangerine. And the ... Read more »

A mushroom on the cover

by stajich in The Hyphal Tip

I’ll indulge a bit here to happily to point to the cover of this week’s PNAS with an image of Coprinopsis cinerea mushrooms fruiting referring to our article on the genome sequence of this important model fungus.  You should also enjoy the commentary article from John Taylor and Chris Ellison that provides a summary of some [...]...

#evol2010 day 3: In which butterflies self-medicate and Orr conjectures

by Jeremy Yoder in Denim and Tweed

How do you know it's getting to be the end of the Evolution 2010 meetings? Because I didn't get to this until this morning, in the back rows of the SSE symposium on evolutionary prediction. But the third day of the meetings were great, with cool natural history and a great address by SSE president H. Allen Orr.

And don't forget to check out the daily wrap-up audiocast over at Evolution, Development, and Genomics, which was just endorsed by none other than Carl Zimmer.

Cultured Stem Cells Used to Restore Vision Loss Caused by Corneal Burns

by avi_wener in American Biotechnologist

A recent study published in the New England Journal of Medicine reported that autologous limbal stem cells can be used to permanently reverse the loss of vision caused by ocular burn induced limbal stem-cell deficiency (limbal stem cells function to replace dead corneal cells).
It is important to note that in the cases reported, eyesight [...]... Read more »

Design of Agile Supply Chains

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management


I already reviewed two other articles about agile supply chains. One on the role of distribution centers in supply chains and one on the migration from lean to agile supply chains.

But the question comes to mind if lean and agile supply chains have to be mutually exclusive or if it is possible to combine them. Christopher and Towill (2001) had a look at this question regarding the supply chain design. Continue reading "Design of Agile Supply Chains"

Red-green colour blindness and advanced bladder cancer

by Euan in Dr Euan Lawson| Doctor Writer

I am red-green colour blind and I’m well aware of my general inability to distinguish red particularly well. In particular, I often miss subtler shades of pink. Apart from a tendency to wear inappropriate shirt and tie combinations it’s hardly life threatening. However, it is perhaps rather more than an inconvenience that blood is red. [...]... Read more »

Switching TNF to the ‘dark side’ – how a cancer killer becomes a cancer promoter

by Cancer Research UK in Cancer Research UK - Science Update

Our immune systems are highly trained to recognise and destroy foreign invaders such as bacteria and viruses. But cancer starts from our own cells, so it’s difficult for the immune system to recognise and fight tumours. However, our immune defences do have some powerful weapons at their disposal, including a molecule called tumour necrosis factor, [...]... Read more »

The chemistry of an iPhone

Apple’s Steve Jobs has a reputation for responding personally to some of the presumably millions of emails he receives.

One from “Derick” published on Wired and elsewhere purportedly asked about the chemistry of the iPhone 4. Derick [...]... Read more »

A glimmer of hope for childhood obesity prevention!

Good gravy! In an early release from the New England Journal of Medicine, researchers documented the effects of a 3 year, 21 school, 4,600 student, multi-pronged, intervention that spanned Grades 6 through 8 covering nutrition, physical activity, behavioural knowledge, communications and social marketing on the children's body mass indices, waist circumferences, fasting glucoses and fasting insulins.The nutritional component targeted quantity, quality and energy of foods.

Interface Systems Evaluation & Innovation

"A state of institutional denialism"

by PalMD in White Coat Underground

Over a quarter century ago, a young woman was admitted to a New York hospital with fever and agitation. She never walked out. Libby Zion died while under the care of he primary care doctor and two medical residents. The exact cause of death was never identified, but the case led to a forced examination of medical residents' work hours. This was driven largely by Zion's father who felt that his daughter had been killed by inexperienced, poorly supervised, and overworked resident physicians.

Postpartum Depression and Mass Media

by Dr Shock in Dr Shock MD PhD


About 13 to 19% of new mothers experience depression in the first year after birth. Most of them are never identified nor diagnosed. New mothers often read about pregnancy, giving birth and raising their children in popular magazines. It’s eminent that adequate information in these magazines about postpartum depression is of importance. A recent study [...]

Regeneration of Tooth Enamel: Cavities Healed in Mice

by Reason in Fight Aging!

Dental researchers are forging ahead with their branch of tissue engineering and regenerative medicine. It hasn't been long since engineered growth in situ of replacement teeth was demonstrated in rats, and now a research group has shown they can regenerate tooth enamel in mice, thereby healing cavities: A new peptide, embedded in a soft gel or a thin, flexible film and placed next to a cavity, encourages cells inside teeth to regenerate in about a month ... The gel or thin film contains a pepti........ Read more »

Can oil and water mix?

by Michael Clarkson in Conformational Flux

We all know that linear polymers of amino acids (proteins) adopt complex three-dimensional structures when they are dissolved in water. The process of forming these structures is called folding, and it is understood to occur because proteins are amphiphilic. Some parts of a protein chain like to interact with water (hydrophilic), while others are oily and want to get out of water (hydrophobic). Folding of the chain sticks all the oily parts together on the inside of the structure while the parts........ Read more »

The Extinction of the Hundsheim Rhino - Being a Generalist Isn't All It's Cracked Up to Be

by Laelaps in Laelaps



The skeleton of the Hundsheim rhinoceros, Stephanorhinus hundsheimensis. From Kahlke and Kaiser, 2010.


In any given environment, it might be expected that a generalized or unspecialized species might be less prone to extinction than one which depends upon a narrow temperature range, a peculiar kind of food, or other aspect of natural history which is key to its survival. An herbivorous mammal which can subsist on a variety of grasses, leaves, and other plant foods, for example, may be more l........ Read more »

Photons: Still Bosons

by Chad Orzel in Uncertain Principles

Last week, Dmitry Budker's group at Berkeley published a paper in Physical Review Letters (also free on the arxiv) with the somewhat drab title "Spectroscopic Test of Bose-Einsten Statistics for Photons." Honestly, I probably wouldn't've noticed it, even though this is the sort of precision AMO test of physics that I love, had it not been for the awesome press release Berkeley put together, and this image in particular (grabbed with its caption):
