A University of Texas Health Science Center at Houston study suggests that ancient Chinese herbal formulas used primarily for cardiovascular indications including heart disease may produce large amounts of artery-widening nitric oxide.

Nitric oxide is crucial to the cardiovascular system because it signals the inner walls of blood vessels to relax, which facilitates the flow of blood through the heart and circulatory system. The messenger molecule also eliminates dangerous clots, lowers high blood pressure and reduces artery-clogging plaque formation.

There's great news for movie lovers.   That popcorn slathered in butter at the movie theater may be only mostly bad for you.

Snack foods like popcorn and many popular breakfast cereals contain "surprisingly large" amounts of healthful antioxidant substances called polyphenols, said chemist Joe Vinson, Ph.D., who headed a new study and presented the results at the ACS meeting today.

Polyphenols are one reason why fruits, vegetables and foods like chocolate, wine, coffee, and tea have become renowned for their potential role in reducing the risk of heart disease, cancer, and other diseases. 

Last week we revealed the Top 10 Schools for Science based on the results of a 3-year study performed by US News&World Report. The study ranked the nation’s best science graduate programs, based upon the results of surveys sent to academics in Biological Sciences, Chemistry, Computer Science, Earth Science, Mathematics, and Physics.

So who came out on top? Several universities had a strong showing in one particular science specialty, but the top schools demonstrated high performance in multiple disciplines. Which schools scored the highest across all specialties? Here are the Top 10:

1.    Stanford University

After taking a new approach to developing an effective "electronic tongue" that mimics human taste, scientists in Illinois are reporting development of a small, inexpensive, lab-on-a-chip sensor that quickly and accurately identifies sweetness — one of the five primary tastes. It can identify with 100 percent accuracy the full sweep of natural and artificial sweet substances, including 14 common sweeteners, using easy-to-read color markers.

A large number of hydrocarbon yielding plants like Calotropis procera, Euphorbia antisyphilitica have been reported to yield bio-fuel products. Attempts have been made to increase their growth and hydrocarbon yield potential.

Studies were conducted to improve growth and productivity of these plants under field conditions In Rajasthan, Calotropis procera grows wild while Euphorbia antisyphilitica has been introduced from Mexico. Jatropha grows wild in south east Rajasthan which lies on south east side of Aravalli hill range which roughly divides the state in semi-arid and arid regions.

"Devil's claw" is a plant that may hold a natural for arthritis, tendonitis and other illnesses that affect millions each year.

Years of drought in Africa's Kalahari Desert have pushed the Devil's claw toward extinction but scientists are making headway in efforts to produce the valuable medicinal chemicals of the Devil's claw and one group reported an advance at the American Chemical Society (ACS) meeting. The researchers described the first successful method of producing the active ingredients in Devil's claw — what made it a sensation to natural medicine proponents in Europe.

They say their technique could lead to the development of "biofactories" that produce huge quantities of rare plant extracts quickly and at little cost.

One of the biggest mistakes environmentally conscious people make is thinking that an 'organic' pesticide is somehow superior to an inorganic one.   The word 'organic' may be the most misunderstood word in western Civilization because there is no structural difference in complex, carbon-based molecules whether they were created in a lab or on a tree.

Nature understands exactly what organic means, including what pesticides are designed to do.  Whether or not a small group of people consider them organic is irrelevant - you won't want to eat food treated with Pyrethrin even though it is considered completely 'organic', for example.   

But marketing wins big battles so people want foods produced in more natural ways - enter rosemary, thyme, clove, and mint.

In discussing individualism and collectivism it needs to be clear that this represents overall philosophical perspectives that aren't confined to simple economic or political interpretations.  Rather these ideas permeate human society, its interactions, and the subgroups within it.

Google “E=mc2 is wrong” and you get 1,060 hits. Google “E=mc2 is correct” and you get a mere 138 hits. There you have it. It took us a more than a century, but finally this crazy inconsistent theory of relativity got outvoted. Common sense cries victory!

Fortunately, science does not work that way. Science is no democracy, and we do not render a theory invalid by popular vote. Einstein's theory of relativity has stood the test of time and its correctness is beyond any doubt. But... there is an issue with what is arguably the most famous equation in the history of natural sciences.
