Transparent mouse embryos and hematopoietic cell clusters

by Erin Campbell in the Node

I was lucky in graduate school and my postdoctoral research—I was a microscopist working on a transparent organism (C. elegans).  Some microscopists don’t have that luxury, but have developed amazing techniques in order to visualize development in organisms such as mice.  In the November 1 issue of Development, Yokomizo and Dzierzak use a technique that [...]...

Antibiotics and gut bacteria

by Lab Rat in Lab Rat

All microbiologists end up writing about gut bacteria at some point. It is the way of things. Disease of the Week is currently doing a whole series on it, and a few weeks ago I covered the interaction of the immune system with gut bacteria (here). However a recent paper came out in Microbiology Today concerning the affect of antibiotics on gut bacteria, which is a topic that I both find interesting and have had some actual experience with.I've taken antibiotics a few times, and each time I've fo........

Fattening Up Microbial Geological Biomarkers

by Paula Welander in Small Things Considered

by Paula Welander

First Evolved! Last Extinct! This prokaryotic pride motto was coined by my undergraduate advisor (and good friend) Prof. Mark Martin. As a microbiologist, I love this motto for many reasons, but especially because it alludes to one of the underlying principles of my current research. Microbes were indeed the first to evolve and the metabolic inventions of ancient microbes greatly influenced the ancient Earth’s environment and the evolution of life. The interaction between ........ Read more »

The Reality of Health Care Rationing

by Rob Mitchum in ScienceLife

Tuesday’s midterm election results appeared to deliver a strong message of discontent to the young Obama administration. With Republicans gaining control of the House of Representatives and closing the gap in the Senate, many analysts saw the election as a rebuke of the Democratic agenda of the last two years. Perhaps the highest-profile of those [...]... Read more »

A Good Cup of Tea

by Isobel in Promega Connections

If man has no tea in him, he is incapable of understanding truth and beauty. ~Japanese Proverb There is nothing like a good cup of tea. On that there is little dispute.

Humor in Scientific Publications

by Samuel Arbesman in

A couple of years ago, two researchers at the Technion tested whether or not funnier scientific article titles yielded higher citations. Their article, Amusing titles in scientific journals and article citation, takes the titles of over 1000 articles and has them rated on two scales, pleasantness and how amusing they are. They then checked to [...]... Read more »

Improvement of Memory in Alzheimer’s Patients Through Music

by Psychology 379 bloggers in Cognition & the Arts

According to the United States Alzheimer’s Association, over 5.3 million people in the US are currently suffering from Alzheimer’s disease. Alzheimer’s is a chronic and progressive form of dementia in which symptoms begin as mild memory impairment and progress into loss of conversational ability, motor function, speech, and the ability to eat. As shown in the illustration below, the disease “eats” neurons in the brain, causing the symptoms discussed above.... Read more »

In 20051, the Liu lab described a new central element in the Neurospora circadian clock. They found that an RNA helicase with similarity to the yeast exosome cofactor Dob1p/Mtr4p, associated with FRQ, a core clock component essential for circadian clock function in this fungus (it was termed FRH, for "FRQ-interacting RNA helicase"). Their evidence suggested that FRH played an important role in ... Read more »

Fan Identity and Team Choice

by Krystal D'Costa in Anthropology in Practice

How does one become a fan? Choose an allegiance? Decide that you’re going to wear bright green, or purple and gold, or paint your face orange and black? In many cases, these allegiances are decided for us—handed down via familial loyalties or decided by geographic boundaries. I raised this question on Twitter a few weeks ago, and the results all indicated that team alliance is linked to one’s point-of-entry into fandom: if you begin watching Team A and learning about the sport via Team A,........

Gold nanoparticles make plants glow in the dark

by Captain Skellett in A Schooner of Science

Imagine if instead of having sensor lights to illuminate a garden path, you could line it with light-emitting plants. You could stroll along bio-luminescent flower beds, dancing in dappled moonlight and delighting in eerily lit peace, free from the shackles of electricity. It could be possible with sea urchin shaped gold nanoparticles. Seriously, every time [...]... Read more »

For group creativity, two narcissists are better than one

by BPS Research Digest in BPS Research Digest

"God is really an artist, like me ... I am God, I am God, I am God." Pablo PicassoSome experts have suggested there's a link between narcissism and creativity. They've wondered if the self-obsession and self-belief create the necessary time and space for originality to flourish. On the contrary, Jack Goncalo at Cornell University has just published results from three experiments which show that narcissists on their own aren't any more creative than usual, even though they think they are.

The Secret Loves of Trees

by Torah Kachur in Science in Seconds

Falling in love is so romantic, so blissful, so cherished in our lives.  Most people will fall in love more than once, first with the 'wait until we're married' sterilizer, then with the 'jealous defender' and finally you hit an age where want to settle down and find the 'practical answer'.  And then, after imminent divorce you find yourself with some gold digger who just can't wait for you to die and leave him or her everything.


That darling of a fairy tale also applies to trees. ........ Read more »

Bruno Bettelheim: A Life of Care & Controversy

by John Wayland in The Darwin Tribune

Bruno Bettelheim is both a controversial and fascinating individual. Below is a Horizon documentary about Bettelheim from 1986. It gives an excellent overview of his life and work. Bettelheim is well-known for his work at the The Orthogenic School. However, Bettelheim is also known as a controversial character. Some suggest his treatment of children in his care was questionable, others maintain he lied about aspects of his past. As well as this, his death by suicide, although sad, seems to ........

Are beached whales and dolphins deaf?

by Grant Jacobs in Code for life

In New Zealand reports of whales stranding on the beaches make headlines, such as the recent stranding of pilot whales at Spirits Bay.[1] They’re mammals like us and New Zealanders have grown up with news stories of whales and their inquisitive cousins, dolphins. It’s pitiful to see these creatures sprawled helpless on the sand.
