What’s News in Science?

Hello students!

Yes you come to my site to check out your assignments and notes, but you can also keep on top of what’s going on in the world of science by clicking on the links below as you have time.  I spend as much time as I can trying to keep current with what’s happening, and WIRED SCIENCE is a great place to do that.  I will post at least one new link per week, so if anything piques your interest, read away and be informed!

Northern Lights visible this week in our area!

Hi Everyone!   Jump in the car and drive out of the city where there are as few lights as possible, Try to find some high ground where you can view the northern horizon, and in the hours just before midnight, you may be able to see some awesome display of lights in the night sky.  Recent solar flare activity on the sun brings hope for some viewing even as low as our latitudes.  Happy hunting!  Here’s the link to Accuweather’s  post.


Taste “map” of your tongue is a myth!

tngeFor years I have been teaching that there are various areas of your tongue that are sensitive to specific tastes: sweet, salty, bitter, sour ( and most recently umami which senses MSG).  As I was researching to once again teach the unit, I stumbled across numerous articles that basically said that everyone for years has accepted this theory of a “tongue map” without questioning the science behind it.  It turns out that research from as long ago as 1974  debunked the myth, but it continues to be taught and displayed in textbooks!

So, to those of you who could never quite understand why your taste buds didn’t fit the “test” with different solutions, you are vindicated!  Everyone IS ABLE to taste all types of tastes everywhere on the tongue, though some areas may have more receptors for specific types of tastes.  Then there is the whole issue of taste buds and whether or not you are a “super taster,” but that we will save for another time.

Here is an article from LiveScience magazine that cites some research, and is an easy read.

Keep on tasting!



A Heart Surgeon Speaks Out

Despite decades of telling people that eating a low fat diet and substituting polyunsaturated oils (such as corn or safflower oil) for saturated fats (like butter) so that their risk of heart disease will be less, doctors have seen a rise in heart disease instead of a drop.  “Statistics from the American Heart Association show that 75 million Americans currently suffer from heart disease, 20 million have diabetes and 57 million have pre-diabetes. These disorders are affecting younger and younger people in greater numbers every year. ” (see article link)

Dr. Dwight Lundell has left his surgery practice to focus on nutrition treatment for heart disease based on  “The discovery a few years ago that inflammation in the artery wall is the real cause of heart disease is slowly leading to a paradigm shift in how heart disease and other chronic ailments will be treated.”  The inflammation is actually being caused by the low fat diet that we have been encouraged to embrace over the last 50 years.

This very interesting (and easily understood) article can be found here.  Food for thought.
