Dandelion seeds use a novel form of flight to get around

Dandelion seeds use a novel form of flight to get around

Science
Oct. 17 (UPI) -- Dandelion seeds fly like no other seeds. In fact, the flight mechanism used by dandelions is one-of-a-kind. The white, fluffy parachutes that help dandelion seeds find new soil to colonize are mostly air. But their novel design allow seeds to float through the air for more than half-a-mile. Advanced 3D imaging helped scientists better characterize the bristles that form each parachute. Using micro-fabricated disks, scientists experimented with different levels of porosity to replicate the effects of the parachute's ball of bristles on air flow. Researchers determined a ring-shaped air bubble forms as air passes through the parachute bristles. The air bubble enhances drag, slowing the seeds descent and allowing more time to be carried away by the wind. The air bubble, whi...

"Syria is green," says Aveen Ismail. "But here it was like a desert until we started growing plants and trees." The 35-year-old fled Damascus with her family in 2012. She now lives in the Domiz Camp in Northern Iraq, where roses, lemon trees and marigolds have sprung up amid the concrete and dust."Creating a garden was a way for us to heal and remind us of home," she says.Alfonso Montiel of the Lemon Tree Trust has sat down in many of the tiny green spaces at the camp."You'll see in some cases it's full of roses," he says. "The first question you ask yourself is, why not food?"Flowers, says Montiel, give a sense of the passage of time. "It gives them a sense of hope. It gives a sense of control of their environment."

The vault storing the world's most precious seeds is taking delivery on Monday of donations that will take it to the one million mark.More than 70,000 crops will be added to frozen storage chambers buried deep within a mountain in the Arctic Circle.Cereal staples, unusual crops like the Estonian onion potato, and barley used to brew Irish beer are among the consignments.Monday marks the tenth anniversary of the Global Seed Vault in Svalbard.One of three chambers is now almost full of packets of seeds, each a variety of an important food crop.The number of donations amounts to 1,059,646. This number excludes one emergency withdrawal of about 90,000 seeds needed to make up for precious samples stranded in Syria due to the conflict there."Hitting the million mark is really significant," said ...

More than 70,000 of the world's most precious seeds have been sent from the UK's Millennium Seed Bank to the Middle East, in its largest export to date.The consignment contains more than 50 wild relatives of cultivated crops, such as wheat, barley and lentils.The seeds will be used for food security research at a seed bank in Lebanon, which is recreating collections destroyed in Syria.The Millennium Seed Bank at Kew is the world's largest wild plant seed bank.Seeds from the resilient, wild cousins of modern food crops are being collected and stored in an international effort.The aim is to breed new crop varieties capable of withstanding threats such as climate change, drought, pests and diseases.''The real importance of these crop wild relatives is that in order to survive in the world the...
