Over-Hyping Genomic Research

by aviwener in Canadian Biotechnologist 2.0

Don’t “over-hype” the promise of genomic medicine. This is the message of a report titled “Deflating the Genomic Bubble” recently published in Science by a team of four internationally prominent genetic medicine and bioethics experts including Timothy Caulfield, Canada Research Chair in Health Law & Policy, University of Alberta, Edmonton, Alberta. According to lead author [...]... Read more »

Early Pregnancy Weight Gain Predicts Gestational Diabetes

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Gestational diabetes and excessive gestational weight gain have significant implications for the health of both mother and child.
Anne-Sophie Morisset and colleagues from Laval University, Quebec City, Canada, now examined the relationship between weight gain early in pregnancy and the risk for gestational diabetes, in a paper just published in the Journal of Womens Health.
The researchers examined [...]... Read more »

Spikes without sodium

by Zen Faulkes in NeuroDojo

Neuroscience is concerned with human, mammals, and vertebrates, in that order. The one example of an invertebrate that appears in many narratives for students learning the field is the squid giant axon, which was used to work out the mechanism underlying action potentials.

From the squid axon, we learned that the action potential, in a nutshell, was:

Sodium in, potassium out.

The electrical signal of a neuron was made possible because charged atoms passed into and out of the cell through chan........ Read more »

Too Much Information? – Labeling Restaurant Menus

by Shaheen Lakhan in Brain Blogger

Information can be a source of learning; but, when there is too much information, or it is not available in a form that can be easily understood and analyzed by the person for whom it is intended, information can be a burden. Or, too much information can simply be ignored in an over-stimulated society. Such [...]... Read more »

Precision tools for DNA editing

by Becky in It Takes 30

Do you long for an easier way to manipulate genomes?  Better methods may be on their way.  In some organisms, such as yeast, it’s relatively easy to introduce or remove specific genes.  In others, it’s tedious and difficult.  Recently, new methods of “genome editing” have been emerging that promise to broaden our ability to manipulate [...]...

Brontomerus mcintoshi – the dinosaur with thunder thighs

by Captain Skellett in A Schooner of Science

Across my twitter feed today we welcomed a new dinosaur. Brontomerus mcintoshi was named for it’s “thunder-thighs” and as honour to retired physicist and avocational paleontologist “Jack” McIntosh. I hope Jack has no hang-ups about his thighs, as I can assure you if someone called a dinosaur “Thunder-thighs skelletti” I would whap them with my [...]... Read more »

Supply Chain Risk Sources, Consequences, Drivers and Mitigation

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

I just stumbled upon one of the articles I already read about a year ago, shortly after I started my research. Beside indication of a future research agenda (see as well here), Jüttner et al. (2003) also explain some fundamental concepts of supply chain risk management.

How to get there?
Jüttner et al. decided to conduct a exploratory study with practitioner interviews and compare these results with a literature review. Four basic concepts for Supply Chain Risk Management evolved from th........ Read more »

Of Stuttering Mice and Stammering Kings

Psycasm - For the Benefit of Other Patrons, Please Refrain from using your Mobile Phone. You Dick.

 In 1994 Monk and friends investigated why people on mobile phones are annoying. You know what I'm talking about. When you're sitting on a train just minding your own business and you heard the dingle-dingle of someone's phone and you just know you're going to hear all about someone's baby / Saturday night / shopping list / job.

Why non-religious Americans die younger

by Tom Rees in Epiphenom

If you're 55 right now and living in the USA, this graphic shows you how much longer you have left to live!

The data come from the Health and
Retirement Study, which was started back in 1992 and has been following a group of 18,000 Americans ever since. Over that time, just over 4,000 have died.

In a new analysis, Allison Sullivan of the Population Studies Center at the
University of Pennsylvania has looked how religiosity in 1992 was linked to early deaths later on. The top-line results are i........ Read more »

A team of Japanese scientists have found the most sarcastic part of the brain known to date. They also found the metaphor centre of the brain and, well, it's kind of like a pair of glasses.The paper is Distinction between the literal and intended meanings of sentences and it's brought to you by Uchiyama et al.

Naps Boost Cognitive Performance in Seniors

by William Yates, M.D. in Brain Posts

Insomnia is a common complaint among elderly individuals. With aging, there is a pattern of decreased number of total sleep time and reduced time in deep sleep. Deep sleep is considered restorative sleep, an important component of feeling rested and alert the following day.Sleep hygiene recommendations commonly warn against napping during the day time as it is felt to reduce the quantity and quality of sleep at night. However, many individuals report that napping during the day is helpful for........ Read more »

Plants rockin’ the suburbs, animals not so much

Where there are more people, there’s less nature. It’s a fairly well established fact. Manhattan may have the odd hawk or falcon, but the paved island’s diversity of plants and animals just can’t compare to that of 23 square miles of pristine wilderness. What’s less known is how well biodiversity fares in human landscapes that [...]... Read more »
