Organic Tomatoes Have More Vitamin C And Sugars Than Fruit That Is Grown Conventionally
2013-02-21 08:25:00

Public Library of Science Tomatoes grown on organic farms accumulate higher concentrations of sugars, vitamin C and compounds associated with oxidative stress compared to those grown on conventional farms, according to research published February 20 in the open access journal PLOS ONE by Maria Raquel Alcantara Miranda and colleagues from the Federal University of Ceara, Brazil. In their study, the researchers compared the weights and biochemical properties of tomatoes from organic and...

Study Suggests Carbon Nanotubes May Protect DNA From Oxidation
2012-11-15 14:01:10

National Institute of Standards and Technology (NIST) Researchers at the National Institute of Standards and Technology (NIST) have provided evidence in the laboratory that single-wall carbon nanotubes (SWCNTs) may help protect DNA molecules from damage by oxidation. In nature, oxidation is a common chemical process in which a reactive chemical removes electrons from DNA and may increase the chance for mutations in cells. More studies are needed to see if the in vitro protective effect of...

Promising Therapy For Huntington’s Disease Developed
2012-11-01 15:43:50

Lawrence Berkeley National Laboratory Initial results in mice could lead to new way to fight neurodegenerative diseases There´s new hope in the fight against Huntington´s disease. A group of researchers that includes scientists from the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice. The compound is a synthetic antioxidant that targets mitochondria, an...

The study of an oxygen-sensing bacterial regulatory protein by chemistry researchers at the University of Georgia has provided molecular insight into the oxygen sensing mechanism, which could ultimately lead to a better understanding of the ageing process and new treatments for human diseases such cancer, Parkinson's and Alzheimer's. Michael Johnson, a distinguished research professor of chemistry in the UGA Franklin College of Arts and Sciences, and Bo Zhang, a UGA chemistry doctoral...

Fruit Flies Enjoy Longer Life With Acai Berries
2012-08-22 14:42:11

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from Emory University recently discovered that acai has the ability to counteract oxidative stress and lengthen the lifespan of fruit flies. In the study, the scientists studied an acai berry product that could lengthen the lives of fruit flies. The health of the fruit flies was originally affected by oxidative stress, but certain conditions of a simple sugar diet and acai supplementation tripled the flies´...

A new and powerful class of antioxidants could one day be a potent treatment for Parkinson's disease, researchers report. A class of antioxidants called synthetic triterpenoids blocked development of Parkinson's in an animal model that develops the disease in a handful of days, said Dr. Bobby Thomas, neuroscientist at the Medical College of Georgia at Georgia Health Sciences University and corresponding author of the study in the journal Antioxidants & Redox Signaling. Thomas and...

Why do we age, and what makes some of us live longer than others? For decades, researchers have been trying to answer these questions by elucidating the molecular causes of aging. One of the most popular theories is that the accumulation of oxygen radicals over time might be the underlying culprit in aging. Oxygen radicals are chemically reactive molecules that can damage cellular components such as lipids, proteins and nucleic acids, resulting in "oxidative stress." The possible link...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
