Plants are among many eukaryotes that can “turn off” one or more of their genes by using a process called RNA interference to block protein translation. Researchers are now weaponizing this by engineering crops to produce specific RNA fragments that, upon ingestion by insects, initiate RNA interference to shut down a target gene essential for […]
Healing Power Of Aloe Vera Proves Beneficial For Teeth And Gums
The aloe vera plant has a long history of healing power. Its ability to heal burns and cuts and soothe pain has been documented as far back as the 10th century. Legend has it that Cleopatra used aloe vera to keep her skin soft. The modern use of aloe vera was first recognized the 1930s […]
Engineers Create Plants That Glow
Imagine that instead of switching on a lamp when it gets dark, you could read by the light of a glowing plant on your desk. MIT engineers have taken a critical first step toward making that vision a reality. By embedding specialized nanoparticles into the leaves of a watercress plant, they induced the plants to […]
Science Confirms You Should Stop And Smell The Roses
Short nature intervention can bring out the best in people. Is it any wonder that most happiness idioms are associated with nature? Happy as a pig in muck, happy as a clam, happy camper. A UBC researcher says there’s truth to the idea that spending time outdoors is a direct line to happiness. In fact, […]
Patients With Drug-Resistant Malaria Cured By Plant Therapy
When the standard malaria medications failed to help 18 critically ill patients, the attending physician in a Congo clinic acted under the “compassionate use” doctrine and prescribed a not-yet-approved malaria therapy made only from the dried leaves of the Artemisia annua plant. In just five days, all 18 people fully recovered. This small but stunningly […]
Risks from Lawn Care Pesticides
Pesticides are intentionally toxic substances. Some chemicals commonly used on lawns and gardens have been associated with birth defects, mutations, adverse reproductive effects, and cancer in laboratory animals. EPA permits over 200 different pesticides to be used for lawn care, and these are often mixed together and sold as chemical combinations. Approximately 35 pesticides are […]
Genetically Modified Golden Rice Falls Short On Lifesaving Promises
Heralded on the cover of Time magazine in 2000 as a genetically modified (GMO) crop with the potential to save millions of lives in the Third World, Golden Rice is still years away from field introduction and even then, may fall short of lofty health benefits still cited regularly by GMO advocates, suggests a new […]
Indoor Plants Can Reduce Formaldehyde Levels
Researchers are studying the ability of plants to reduce formaldehyde levels in the air. A study led by Kwang Jin Kim of Korea’s National Horticultural Research Institute compared the absorption rate of two types of houseplants. The results of the experiment on Weeping Fig (Ficus benjamina) and Fatsia japonica, an evergreen shrub, were published in the […]
FDA concludes GMO Arctic Apples and Innate Potatoes are safe for consumption
The U.S. Food and Drug Administration completed its evaluation for two varieties of apples genetically engineered by Okanagan Specialty Fruits, Inc., and for six varieties of potatoes genetically engineered by J. R. Simplot Company and concluded that these foods are as safe and nutritious as their conventional counterparts. Okanagan’s Granny Smith and Golden Delicious varieties […]
X-rays reveal uptake of nanoparticles by soybean crops
Metals contained in nanoparticles can enter into the food chain. Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analysed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout the plants, whereas the element cerium did not dissolve into plant […]
