This insightful article examines children’s understandings of comic books over time using a Western comic A Gunman in Town!. The study looked at ten children in each of 3rd, 5th, and 8th grade, balanced for gender and race with diverse socio-economic status. They were shown each frame individually and asked its contents following each panel. This might not have hugely hampered the sequential understanding though, since the panels seem largely dominated by text.All the children recognized broad........ Read more »
The many benefits of growing a mixture of crop varieties together have now been demonstrated for many crops under many conditions. Latest entry is in a kind of specialised niche — organic tomatoes for processing — and the results are a little underwhelming. Three scientists at the University of California, Davis, grew one, three or [...]... Read more »

The future of medicine, we are told time and time again, is genetic and personalized. Someday, physicians will call up the genetic code of a patient and determine their genetic risks and which treatments will work most effectively with the fewest side effects. That information can be organized into individual, unique medical plans for each [...]... Read more »

an exploration into connections between the sensory modalities of a marine predator.
Cephalopods are known as the ‘charismatic megafauna’ of the invertebrate world. We humans are generally fascinated by their stealth, their ability to camouflage, and their massive brains. The physical form of cephalopods is so different from our own that we find them [...]... Read more »

By: Dr. Ken Broda-Bahm - In his recent State of the Union address, President Obama followed the common pattern of giving attention and applause lines to nearly every issue on the national agenda. But there was one issue that received no mention at all: climate change. The absence, noted by many commentators, extended even to areas where it would have been natural to mention the environment. The President's "clean energy" initiative, for example, was touted based on its ability to create jobs and........ Read more »

Masiakasaurus was a weird-looking dinosaur. The paper that first described it was titled “A bizarre predatory dinosaur from the Late Cretaceous of Madagascar.” What made it so strange were its teeth. At the front of its lower jaw, this six-foot theropod had forward-tilted teeth much different from those of its larger cousin Majungasaurus, which lived [...]... Read more »

Stress tests are an acknowledged method to test systems under extreme conditions. The method is not only used in engineering (eg. Great picture of a Boing wing stress test (Guardian Eyewitness)), but also in business, most notably and in the banking industry. But can this method also be used to test supply chain designs?

There is limited literature on using simulation to evaluate supply chains under stress. The authors took the following approach: Determining the scope ........ Read more »

The arms race of sequencing has always been about throughput. The big players (Illumina and Life Tech technologies) have engaged in a continual game of one-upmanship over the last few years. As a result, we’ve seen yields skyrocket to from 10 gigabases per run to the current and outrageous 180-200 gb on the HiSeq. Good [...]... Read more »

If your client is African American, jurors will demonstrate to you that the answer is much more likely to be yes. And the more stereotypically black (with darker skin and wider nose)—the more likely the death penalty will be assigned. Hard to stomach? Yes. Hard to believe? We didn’t think so. But it is pretty [...]

It's been more than 10 years since it was noticed that certain enzymes – the sirtuins – had life-extending properties in organisms like yeast, and later nematodes, fruit flies, and mice. The excitement spread to other compounds, such as resveratrol, that seemed to activate or assist sirtuins. Hopes were high that such things might offer the known longevity benefits of calorie restriction in a pill form. Ever since then the gold rush has been on to figure out how these things work &nd........ Read more »

The scientific community often discusses the misrepresentation of health news by the media. A less discussed subject is misrepresentation of data in the scientific literature.
