At least 40% of pharmaceuticals are derived from plants, according to the USDA’s website.  Many of these have been used to treat common ailments for hundreds, sometimes thousands, of years.  Examples include willow bark which contains aspirin’s active ingredient and emetine from ipecacuanha which is used to induce vomiting when someone accidentally ingests a poison.  You may more readily recognize it as Ipecac syrup.  These and similar ailments have bothered humans for as long as we’ve existed.  But can plants defeat illnesses associated with modern lifestyles?

The answer is probably yes.  A research team from the University of South Florida Health found preliminary evidence that Basil (Ocimum) may help protect the brain against Alzheimer’s disease.

Basil plants have an abundant natural compound called fenchol.  You may already be familiar with this compound even if you don’t know its name.  Fenchol contributes to basil’s delicious smell.  Additionally, in preclinical studies conducted in non-human disease models, fenchol affects two critical brain chemistry processes.  As a result, the fenchol reduces neurotoxicity in the brain that is associated with Alzheimer’s.

Once again, possible answers to our most perplexing problems lie within our environment.  This time, it may be an ingredient in your dinner!

Can you guess how far a dragonfly that weighs 1/100th of an ounce will migrate?  How about 1250 miles, including flying over open seas.

A team lead by researchers from Lund University in Sweden discovered that the Globe Skimmer Dragonflies (Pantala flavescens) migrate from India to East Africa each spring.  Approximately 15% of them survive the lengthy journey.  About 40% manage to make the return trip in the autumn.  

These dragonflies cannot travel this distance solely based on the fuel from their fat stores.   They are simply too small.  Instead, they must gauge the wind currents to push them along the way.  We’ve seen this in birds as well. 

This type of research is often derided as wasteful.  Who cares how far this dragonfly travels?  In response, the team notes that this type of research increases knowledge of how migratory animals, including insects, may inadvertently spread disease.  As wind patterns shift due to climate change, this information will be invaluable to predicting illness breakouts in new locations.
