Design Language Gushes Out of Article Describing Cell Quality Control

Here are the design words found in a press release from Michigan State describing the editing mechanisms of the cell DNA-to-RNA transcription process: high fidelity, quality control, inner workings, genetic coding, exquisite nanotechnology in living systems, genetic control, blueprint for life, industrial assembly line, conveyor belt, preloading, criteria, backs up to correct the error, sensed […]

Your Eyes Do Layered Image Processing

Computer users familiar with Photoshop and other image processing programs know that an image can be divided into “layers” for making color corrections, evening out contrast and enhancing details.  Your eyes do that, too, says Alan Gilchrist in Current Biology.1  He shows a stunning optical illusion to make the point: transparent chess pieces against differing […]

Do Neurologists Understand Brain Evolution?

Jane Bradbury wrote a feature piece for PLOS Biology recently,1 entitled, “Molecular Insights into Human Brain Evolution.”  Help us find the insights.  First, she marvels on how “humans sit on top of the pile when it comes to relative brain size.”  Then she marvels at how quickly the human brain apparently evolved compared to apes.  […]

If I Only Had a Brain…

The scarecrow didn’t know what he was asking for.  Look what Steven E. Hyman of Harvard says about the human brain and nervous system in the 8 March 2005 issue of Current Biology:1 The nervous system processes sensory information and controls behavior by performing an enormous number of computations.  These computations occur both within cells […]

Are Humans Still Evolving?

Science Now asks the question, “are humans still evolving?”  Comparisons of genes and chromosomes between different people groups from Asia, Europe and Africa are challenging the view that there is one human genome.  Some long stretches of DNA are inverted in some groups, and women so affected seem to have more children on average, even […]

Robots Don’t See as Well as You Do

Robot designers are still working on ways to emulate the human eye.  Just when you thought digital cameras were all the rage, we learn from EurekAlert they are miserable substitutes when put into the eye sockets of robots.  Robot-vision export Vladimir Brajovic explains: Often, when we take a picture with a digital or film camera, […]

Why You Breathe Deep to Sniff a Flower

It may sound like a 747 when your uncle blows his nose, but scientists at Imperial College found nose airflow to be more complicated than the aerodynamics of a jumbo jet’s wing, according to a press release by the reporting the Biotechnology and Biological Sciences Research Council .  They made a 3D model of the […]
