Cancer and Diabetes: Any Connection?

by Steve Parker, M.D. in Diabetic Mediterranean Diet Blog

Type 2 diabetes is associated with higher incidence of several cancers: liver, pancreas, uterus, colo-rectal, breast, and bladder.  On a brighter note, diabetics have lower risk of prostate cancer. That’s about all we know for sure, according to a report from an expert panel convened by the American Diabetes Association and the American Cancer Society [...]... Read more »

…the Science of Dragon slaying and Cop killing

by Rift in Psycasm

At the end of semester I always experience a kind of slump. I try to put it off as long as possible but it generally wins. I can broadly categorize it as a period of really high productivity during exams, then a lull where I have no external drive to be productive. I start my [...]... Read more »

Are we conscious or unconscious consumers?

by NeuroKüz in NeuroKüz

What if I put you in a brain scanner for a few minutes and told you to stare at a black square, then I looked at your neural activity, and then I told you: “You might as well stop fighting those hidden urges. Go out and splurge on that 77’ Pinto station wagon you’ve wanted all these years.”Would you glare at me as if I were some kind of mad scientist turned psychic-wannabe? Or would you nod in embarrassment because you read about a study that was recently published in the Journal of Neur........ Read more »

Effectiveness of Antidepressants

by moodrhythms in Mood Rhythms

A while ago I came across an article by a researcher named Joanna Moncrieff who has written a number of reviews of antidepressant meta-analyses. I believe what she said at that time is still relevant today. In an article titled, “Are antidepressants as effective as Claimed? No, They Are Not Effective at All”, she pointed out in the article what I had also noticed about some of the more commonly used depression tests. Rating scales of tests often contained items like sleeping difficulties, an........ Read more »

#evol2010 day 4: In which the race is not always to the swift, and giving up on sex isn't a dead end

by Jeremy Yoder in Denim and Tweed

The final day of Evolution 2010 featured a fantastic series of talks in the ASN Young Investigators Symposium, and marked the premiere of the iEvoBio sister conference, which ran concurrently today. Perhaps not surprisingly, the #ievobio tag quickly outran the #evol2010 tag on Twitter.

I'm ending the conference with a final wrap-up audiocast with the crew from Evolution, Development, and Genomics, and then hopefully a quick run before the closing banquet.

NEWS: Texas canyon carved in just three days

by Casey Rentz in Natural Selections

Normally, geologic events happen over hundreds of thousands of years. In January, I was surprised to read that the Mediterranean sea may have filled with ocean water in a mere two years. (Check out that post at the Lay Scientist.)

Again--I am surprised to find that in a mere three days, floodwaters carved this impressive 2.2-kilometer-long and 7-meter-deep canyon in solid Texas bedrock. In 2002, a particularly menacing rainstorm sent water gushing over Canyon Dam in central Texas, carving thi........ Read more »

Social Networks Help World Cup Spectators Cope With Chance

by Krystal D'Costa in Anthropology in Practice

Given the reduced volume of World Cup related posts in my Twitter and Facebook streams, it appears that soccer fever is abating the in US. The reach of the World Cup has been far this year, thanks in part to the role of social media outlets in encouraging discussion and raising awareness about the sport. For a few weeks, Twitter and Facebook were inundated with World Cup related posts, with

A bull in a bear market: Social media and the scientist “shortage”

by Zen Faulkes in NeuroDojo

Joshua Ward thinks scientists have to embrace social media.

Okay. As a blogger, someone on Twitter, and so on, I guess I can’t disagree with that.

But almost didn’t get to that point, because I just about did a spit-take when I read:

In the face of basic scientist shortages in many of the leading fields(...)
Shortage? What shortage? I rarely read about institutions unable to find good people. I read a lot about institutions with bona fide research positions that are swamped by application........ Read more »

North Sea Genomes

by Lucas in thoughtomics

If coral reefs are the rain forests of the tropical oceans, kelp forests are the woodlands of the Northern seas. Kelp is one of the algal species that can survive the harsh conditions of the North Sea that I know and love, together with other hardy seaweeds like bladder wrack. All these seaweeds [...]...

A Heavy Load

by Journal Watch Online in Journal Watch Online

To stave off global warming, some people have proposed sequestering huge amounts of carbon dioxide in the ocean or geological formations. But society could be paying the price for that strategy for thousands of years, a scientist argues in Nature Geoscience.
Gary Shaffer of the University of Copenhagen in Denmark ran the numbers on several […] Read More »... Read more »

It’s a small (RNA) world after all

by Iddo Friedberg in Byte Size Biology

The central dogma of molecular biology as formulated 57 years ago was simple: DNA is transcribed to mRNA,and  mRNA is translated to proteins. Proteins are the business end of this process. mRNA is only the messenger: its sole function is to deliver information from the template (DNA) to the business end (Protein). It was thought [...]...

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

#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

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 »
