Nano-Watch Has Steady Hands

Nanorod.png

An international team from the Universities of Vienna, Duisburg-Essen and Tel Aviv have created a nanomechanical hand to show the time of an electronic clock, by spinning a tiny cylinder using light. A silicon nanorod, less than a thousandth of a millimetre long, can be trapped in thin air using focussed laser beams, and spun to follow the ticking of a clock, losing only one-millionth of a second over four days.

Snoring Sounds Provide Insight for Obstructive Airway Disorders

Often unnoticed by the patient, Obstructive Sleep Apnea results in fragmented sleep patterns causing daytime fatigue and cardiovascular problems. However, the question remains of how to differentiate normal snoring from sleep apnea. Researchers will present their results on the 3-D modeling of uvula vibrational patterns and sound frequencies during snoring at the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, 2017.

Bursting Citrus Peel Oil Glands Inspire New Approach for Microjetting Fluids

When was the last time you took a close look at an orange, lime or lemon peel? Outer citrus peels are covered with tiny oil glands or cavities that can explode in an outward direction, often spraying toward you, if bent in an attempt to gain access to the inner fruit. Researchers at the University of Central Florida set out to explore how the material properties during this phenomenon enable the production of these high-speed jets that often go unnoticed or unappreciated, even by avid citrus consumers. They’ll discuss their work at the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, 2017.

Imaging Technique Unlocks the Secrets of 17th Century Artists

The secrets of 17th century artists can now be revealed, thanks to 21st century signal processing. Using modern high-speed scanners and the advanced signal processing techniques, researchers at the Georgia Institute of Technology are peering through layers of pigment to see how painters prepared their canvasses, applied undercoats, and built up layer upon layer of paint to produce their masterpieces.

Ancient Barley Took High Road to China, Changed to Summer Crop in Tibet

XinyiLiu200.jpg

First domesticated 10,000 years ago in the Fertile Crescent of the Middle East, wheat and barley took vastly different routes to China, with barley switching from a winter to both a winter and summer crop during a thousand-year detour along the southern Tibetan Plateau, suggests new research from Washington University in St. Louis,

New Research Details Genetic Resistance to Sudden Death Syndrome in Soybeans

Incorporating a combination of genes from the model plant Arabidopsis may build high levels of resistance to sudden death syndrome in soybeans, according to research from an Iowa State University agronomist. A recently published study points to one gene in particular as a likely candidate to bolster resistance.

Study Pinpoints Arctic Shorebird Decline

Red-neckedphalarope_ZakPohlen.jpg

A new study co-authored by WCS (Wildlife Conservation Society) addresses concerns over the many Arctic shorebird populations in precipitous decline. Evident from the study is that monitoring and protection of habitat where the birds breed, winter, and stopover is critical to their survival and to that of a global migration spectacle.
